over the years i've seen some creative stuff done with pit boxes however at neko con spoon and i met up with a past friend that simply had some cool inspector gadet type stuff done to his box. this inspired me and spoon to modify out own pit boxes.

i wanted to share my plans and ask some questions.

i sequestered my sons pit box since he's down to one car and i can fit that in my box.

1. i plan on modifying the two top storage bins to be fan cooling stations.
2. i will mount my power supply inside the box and cut out vent hole for the fan and a hole for the power cord. i will then run the two 12v leads to plug mounted on the side of the box and maybe a few of the lesser voltage leads for maybe breaking in motors or whatever.
3. i would like to attach a surge protector to the rear of the box so that all i have to do is plug that in to an extension cord and plug all my stuff into that.
4. the goal is to have enough space left to store my battery charger, cell charger and soldering equipment

i found some cheap led cooling fans, 80mm however they are a little big for my needs/space. compusa had a crappy selection so i think i'm left ording online. does anyone have any reccomendations for 60mm or there abouts size pc cooling fans? possibly illuminated?

radioshack had crappy audio jacks to choose from. where can i find some decent spring type connectors that you find on real rc chargers?

question regarding a 3 pin fan... i already have a 2 pin fan hooked up to my power supply. for a 3 pin, can i just cut off the 3rd wire? i fans will be controlled by a switch so all i need are the + and - wires.

spoon, what fans did you use? i just tested the 80mm and they are less powerfull than the 60mm fan i have :mad:

how well will hot glue adhear to plastic tool boxes? i was just going to hot glue all the fans, etc. in place vs. using screws everywhere

Hot glue should work well, though as spoon pointed out it may be hard to work with in larger amounts (it cools quickly). It would definitely be preferable to epoxy if you ever want to disassemble/replace items. Not sure how well it will hold up over time though (it adheres well, but it doesn't stand up to torsion/flex).

As far as the wires for the fan go, there are typically more than one positive lead with PC power supplies...yellow is 12v positive, red is 5v positive (and of course black is negative). What is the voltage rating for the fan? If it is rated 5v you should probably cut out the yellow wire. If it is rated 12v and you are using the red as positive it is probably going to run at half speed (you will want to cut out the red if it is rated 12v). You could also wire up a 3 way switch if it is 12v, allowing you variable speed. ;)

He is using PC fans, I believe he was referring to hot glue as an alternative to drilling/screwing. Screws are a more modular choice, hot glue is quick and dirty. :D

instead of hot glue, and epoxy, you can use silicon caulking, it is easy like hot glue, but cures slower.

my power supply only has 2 12v leads. i have to use one for hte dc charger. how much of a decline in performance do you expect 4 of these mad dog fans will have all being wired from one 12v lead?

i can crack open the ps to see if there are any more 12v leads but i don't think there are., ok, just checked... there are 4 so thats good news.

I dont think that you will lose much performance at all with a few of the 80mm fans coonected to one PC Power supply lead... what is the PSU rated at on the 12v rail? The fans you are using have very little amperage... Most of the time in my PC's I hook up all of the system fans to one lead... I normally use much more powerful fans in my PCs.

For cheap fans and fan controllers, you can look at www.SVC.com or www.jab-tech.com The fan controllers work as a fanbus, plus you get to control the speed of the fans (some controllers you have the ability to turn the fans off entirely). I have had the best results using the 4 port Sunbeam controller with the higher power fans, however, if you are using a less powerful fans, almost any controller should do the trick. You only need the 2 red/black wires. The third yellow or white wire on the fan only gives a readout of the fans speed, it will not control it.

so this is a bit overkill but would be cool none the less,

4 tornado fans in total

it seems this setup would be the most plug and play route vs. cutting wires and doing alot of soldering.

http://www.svc.com/80torfan.html

I use those fans in all of my PC's... mainly for CPU and exhaust :p
They are quite loud... the fans have fins on the exhaust side to control the airflow towards the center of the fan...

Looks like a little overkill... but thats the beauty of it...

Make sure that the PSU you are using, has enough amps on the 12v rail to power both the fans and the chargers all at once... if it is an old PSU, it may not... the fans will draw around 1.5A or more at startup... and try to keep the amp draw below 75% of the PSU's rated capacity.

The PSU should have a label on the side with the ratings for each rail. Older PCs used mainly the 3.3v and 5v rails, with little use of the 12v rails... modern PCs use mainly the 12v rail or rails (most new PSUs have more than one 12v rail mainly due to the power that is required for modern video cards). An older PSU may only have 5-10A on the 12v rail, while modern PSUs will have at least 30A on the combination of the 12V rails... for any new system, I allways look for at least 30A on the PSU that I am going to use...

If you have the model number for the PSU, I may be able to dig up some info... Is the PSU an ATX or an AT PSU? Most ATX PSUs would have at least 10A on the 12v rail...

spoon, what fans did you use? i just tested the 80mm and they are less powerfull than the 60mm fan i have :mad:

Sorry I am coming into this thread so late...When I update my blog post on my box I'll post here...

Anyway, onto the answers.

1. Yes you can just not connect the third wire.

2. I have a bunch of fans from some old sun computers. They are 92mm fans and they rock. I have several smaller fans(60mm) and you can usually determine how much air they will move by the current ratings. Typically the higher the current the more air they move...and I have also seen some smaller fans move more air. I think it may be worthwile to setup a testing station before you install the fans.

Spoon
2006.11.21, 11:00 AM
Also, you should be able to power a bunch of fans off of the one PS. I would suggest dedicating at least one fan to intake.

Even with a 92mm hole I can't run the 92mm fan and 60mm fan at full speed with the box closed. I will soon be installing another 92mm fan as an intake as soon as I get a grate to cover the fan blades.

And I would definitely use scres to mount the fans. It takes a little more time but it makes for a pretty clean installation. I think I am using 1.5" nylon screws that I got from Lowes.

Unfortuanately, I spent more on switches, wire and nylon hardware than I did on the box...and that's with getting the fans for free.

arch2b
2006.11.21, 11:57 AM
yeah, it's going to be some money to get the box done but it's fun none the less. thats most of hte reason why i want to do it.

i'll use the 2 80mm lighted fans i have for intake and get the high output 80x38mm fans for car cooling. i also bought 80mm fan guards as i do not want to loose any fingers or plastic parts falling into the fans. i will even have a wire mesh screen covering them as well.

so, looks like the box will have a total of maybe 6 fans, fan controller, psu and storage space for chargers adn soldering tools.

i still need to find appropriate jacks for hte 12v power to the dc charger. rs only had flimsy audio spring jacks. i was hoping to find something that is a bit more robust.

i would except that i don't know how to mount the deans plug to the box so that it's durable enough to push and pull on. anything might hold for a while but with the constant push and pull to connect/disconnect, it would wiggle loose and pull out/push thru.

Here is what I used. I think I have M-size. The panel mounts fits really cleanly in a drilled hole in the bottom of the box.

I am using this to power my box externally, I am guessing you could use a similar setup to power your charger...

or you could use banana jacks (http://www.radioshack.com/product/index.jsp?productId=2102840&cp=&kw=banana+jack&parentPage=search)
I think the banana jacks might be better for what you want to do. You can just solder banana plugs to your charger and plug them into the side of the box when you need the power.

This almost sounds like the model rocket box idea I had years ago. I had a cheap little plastic tackle box that I kept my engines and fight supplies in. I went to RS to get switches, speaker wire, clips, and AA battery holders. I basicly built my launch controler into the box. I wanted it reliable, so I keep the connections simple. I thought about using plugs, but that was alot more connections you had to make. I figure the more connections, the more problems would show up later. I had it fixed so I can roll up my cord and tuck it inside the box. Just keep it insulated so it didn't short out. This is almost the same thing, but the power source is outside the box.

i took some pictures today.
i installed two lighted switches, they are jsut installed, not wired yet.

i did all the cutting for 2 led fans for 1 cooling station, drilled mounting holes but have not wired anything up

have the power supply all situated properly with cutouts and mounting screws. i still need to go back into the psu and clean up some left over wiring, etc.

i installed 1 set of banana plug jacks and hard wired to deans plug. i will do this for all accessories wored to the psu so that i can just as easily take the psu out for repairs as needed. i also hard wired my charging lead to my half eight cell pack to banana plugs. now i jsut have the epoch leads, my crt leads...

i hope to get the one cooling station all wired up this weekend depending if i cna find some more deans plugs.

i also need to buy some more fan guards for venting holes i will need to cut out to ensure proper air flow for hte cooling stations. the other 2 led fans will have to waiting until dec 1st for payday.

i still want to get the vantec equipment but i also wnat to have this box ready for the pa/ny/dc regional gtg too so i'm getting everything i can done by then and will go back and replace as needed later.

Arch, you inspired me to do one of these for myself. I will be using it for 1/10 scale though. I bought 4 80mm LED fans and Bio-Hazard fan grills. I am mounting 2 fans in the top of the box blowing air out, one to charge my batteries over to keep them cool, and one to sit my car on in between races to let the motor cool off. The other 2 fans aremounted in one end of the box to pull air in. the PC Power Supply is mounted in the opposite end of the box. I am making this to run 2 chargers, and both the chargers have large alligator clamps on the leads, so here is what I did for the connections on those. I crimped ring terminals to the ends of the +12V wires, drilled large holes in the back of the box, and put some large bolts through the box and the ring terminals, and bolted them down. Now the chargers can be clamped on to the head of the bolt just as if we were clamping onto a car battery. There will also be a fan speed controller so I can quieten it down when needed. Also there will be a power inverter inside to run the soldering station from.

My friend mentioned one day last week that we needed to run our battery chargers from a DC voltage source instead of the 110v AC plug, and suggested using a computer power supply. The reason for this is that our chargers (Duratrax Piranha Digital Peak) limit themselves to 3A rate when using 110vAC but will charge at 5A when using a 12vDC 7A supply. We need the faster charge to peak our race packs between heats.

I'll do my best with words...I can also draw a picture and post that in a few minutes.

The Power Supply + lead should go to Pin 1
The Fan + Lead should go to Pin 2
The Fan - Lead and the PS - lead should go to pin 3...

Now...you can connect All of the negative leads to the same place if you want so you only have one connection to the switch. For example, you could wire everything to the same row on a small RS circuit board (like I did) or you can wire everything to same negative banana plug. As long as the fan - terminal is connected to the PS - terminal somewhere you are golden.

Is your switch a momentary switch? I dont think that a momentary switch would work to turn on and keep the PSU on... If you wire a non momentary switch between the green ATX wire and ground, as long as you have enough load on the PSU it will turn on and stay on when the circuit is closed and there is enough load on the PSU...

thanks for your blog. i really enjoy reading it.

those mad dog fans were $10 each. as soon as i get paid i'm going back to get 2 more for hte other side.

looks like i bought the wrong lighted switches though. you have the kind i was looking for but the rs by me only had the ones i installed which apparently i guess only work with ac, not dc. that is light up anyway.

i still need to buy a fan guard for the intake on the opposite side from teh psu. i don't think i'll use an intake fan but cut some more strategic holes where i can to allow more direct airflow. with the lid closed exhaust fans did not put out alo tof air, not as much as yours does. i think 1 80 or 120mm opening will suffice. i have to be careful though as i don't want to take up anymore storage space than i already have. afterall, this has to haul stuff too.

I made the same mistake with the switches. I bought three of them and I wired the first one before I realized my mistake. I was able to return two of them. That's why there are three quarter-sized holes in teh front of my box. The AC swithes were bigger than the DC switches, so I have some spare intake hoels now. :D

I also relate with putting too much stuff in the box. For me it's sort of an overflow box, but I guess if you designate it for certain things (sounds like you have) I guess you'll know exactly what kind of space you are going to need.

If you run into problems with not enough airflow you could always just flip one of tehose fans on the top of the box. It's amazing how much air those fans need to blow at full speed.

Again, nice work, I am looking forward to seeing it in person.

I bought a 4 pack of fans on ebay for a great deal. around $17 shipped, and they look just like the ones Arch used but with red LEDs instead of blue.

crap, went back to buy the other two fans and compusa doesn't carry them anymore. now i have to go back to ebay and hope i can pick them up and install them before the pa trip.
fyi, on antibiotics this weekend, so no work on the box this weekend.... i should be up and kicking again next week.

i did get some more fan guards so i can make the intake hole on the side. i bought 2 120mm guards so i can hopefully place one on the outside and one on the inside. this will prevent items from pushing thru from either side.

i bought some insulated quick disconnects to attach everything to the psu. after thinking about it, using deans plugs is overkill and expensive. much easier to just use cheap insulated connectors. this should allow me to get it all done much faster.

anyone else get any further in thier modifications?

just thought i would share this bit of info, am has 'pit fans' as well as a combo that has a fan wired to a 12v wall adapter. needless to say the price is high for something you can make yourself with a short trip to any pc parts store and or radioshack. the fans are generic as far as i can tell as well. why someone would pay $10 for a generic fan is beyond me when you could get a cool led fan for the same price. i could understand if the output was higher than average but it's not listed in the description so i would assume it's not.

it is intersting that you could easly pickup a 12v wall apadter from rs and make this a simple plug and play item. with a little ingenuity, you could make a cool cooling station that simply plugs into the wall vs. doing the modified pitbox cooling stations.

since i have to carry around most of this stuff anyway, it's jsut as easy for me to incorporate it all into one box vs. carting around plug in cooling stations. atleast this offers everyone options.

is anyone willing to make a plug in cooling station to share with the rest of us?

@ Arch, I am not using the stackable toolbox anymore. The day after the con I took everything out of it and returned it to sears. After seeing Nate's box and deciding what I wanted to do, I realized it wouldn't work. It's too difficult to separate and I don't think it's meant to be taken apart regularly.

That's when I went hunting for the current box.

I agree with you on the separate cooler. I started out that way and it was good for a while but it does take up precious space. I don't think I have seen the AM car cooler. So far all of my fans have been free. If I can find some really cheap 92mm LED fans I may pick some up. I am also still keeping my eyes open for some cheap cold cathode lights too. :cool: But right now it's ready for race day so it may sit that way for a while.

Iam glad that you mentioned this...I was running my AWD the other day (Nelly EVO turbo) and it always heats up the Atomic Standard (AKA DC Spec) motor. I swapped to the Atomic AWD (maybe BB) and it didn't get nearly as hot. I still have some more testing to do, but I figure it would be worth passing along.

I got the fans put into my box today. I put 2 pulling in, and 2 blowing out. I figured since this was the standard with todays Gaming PC's that it made alot of sence. Arch, I got 4 LED 80mm fans off of ebay for around $16 shipping included. I need to look around for a couple more nice 80mm fan grilles. I found a PC power supply on newegg.com that has a 12v current of 20A for only $20 shipping included. I will be using this to power 2 DC battery chargers and the fans in the box.

in respect to adequate enough, I was told by the local computer shop that if your psu has at least 2A higher rating than the charge rate+all the ratings on the fan, then you should be fine.

2006.12.03, 04:54 PM
ok, i managed to get about 10 minutes to work on the box. found out i don't have wire crimps to use the quick diconnects :mad: more time wasted.

i cut out the 120mm venting hole and installed guard grills on either side using scrap plastic home made nuts to screw into and they are in perfect and rock solid. this will offer the chance to install a 120mm fan at a later time if need be. i'll try to get some pictures later.

still left to do is get wire crimp tool, pick up the remaining 2 fans, wire ties to clean up the wiring and just do the actual work.

Nice work guys!!! I knew you were constructing somthing but I only saw the beginning. I'm really impressed as well as inspired. I'm already drawing it up in my head.

For mine though I don't think I'll run everything off the top of the box. I'm going to start with a flat surface inside the box. My plan is to use 2 fans for the car, 2 fans for colling the 15min chargers after the chargers are done charging and a battery discharging tray. I'll have to find some kind of LED voltage indicator for the discharge tray.

I really like the idea behind the computer supply. Out here I have been carrying a heavy 30lb transformer to run my two chargers. With a modified pit box it's all in one and I just need to switch the voltage on the ps and get a UK plug.

Great job guys and keep us posted.

eager to see what you can come up with byebye ;) i personally know you have a nack for creative construction :)

to the dc guys, the auciton i won was a set of 4 fans. at most i can only use 3. anyone intersted in whatever i have left, free ofcourse? i got a great deal on them so in whole, they were VERY cheap compared to the 2 i bought at compusa.

i was thinking about seeing if i could put one of the blue fans in teh psu just for kicks? not even sure they are the same size. it would look better or cool if i could but it's purely for geek factor.

I can charge my 7.2v packs for 1/10 scale at 2.5amps with a simple 1000mA power supply, so any amp rating on the PC power supply should power a couple of 15min chargers for AAA/AA batteries just fine, as they only run at about 1.2-2.5 amps each.

That's a really clean looking install. Nice work! I really like the clean cut for the PSU vent and the banana jacks are well spaced.

One thing you could do for intake would be two flip two of the blue fans. You could either flip one on each cooling bay or just flip to ina single bay. I did some quick testing with one of those temp guns that guys use for nitro engines and the cooler gets the motor back down to normal temperature in well under three minutes. It does most of the cooling in the first minuet so the cars don't need to sit up there very long. So you may not actually need two bays.

But...I don't have a 120mm fan. I think the largest I have is a 92mm. I may have one left that puts out some pretty good air. I'll have to check, let me know if you want it.

I have a few 120mm fans, however I dont think that they are LED fans (I may have one)... I will dig through some of my PC gear, and see what I can find, it may take a few days though...

If you want to order a high powered fan, I would suggest http://www.svc.com/a1926-14.html or http://www.svc.com/120smartcasefanblueled.html These are the only med/high powered 120mm fans you will find with LEDs. Without LEDs you can find higher powered fans http://www.svc.com/kd1212pmb1-86.html

You could use a fan adapter (http://www.svc.com/fa80120-blue.html) to fit a smaller fan... I may have an extra 80mm Tornado or Tt Smart Fan II that I could bring with me to PA this weekend...

In general, ball bearing fans will be more noisy but last longer than sleeve bearing fans...

If you want bright lights.. you could allways look into CCFL fan grills... http://www.svc.com/ccf120bl.html however, you will have to mount the inverter as well as the fan...

To keep the inside of your box fairly dust free, I would suggest having more intake than exhaust. This will force the dust out of small crevices. When you have more exhaust than intake, there will be more dust inside. You may want to use a filter on the main intake http://www.svc.com/120mesh-blu-24.html http://www.svc.com/12mga-blu-11.html or http://www.svc.com/12filguar.html
When I work on a PC, I allways try to keep the intake CFM equal to the exhaust... although this is somewhat different...

Okay here's an update

I went out and picked up 4 80mm fans and one 120mm fan.

2x5.5mm dc plug and cable and grabbed 12v from the power supply.

I hooked up all the fans and used some fork connectors as jumpers and fired it up. First I just fired it up with the fans to make sure I jumpered the right wires. I then wired up the battery chargers and viola' it fired up. At first I charged up a single aaa battery. I did the full test with both chargers charging 15min energizer AA's. I monitored the voltage on a spare plug and was getting anywhere from 11.6v-11.9v with everything on. The chargers charged the batts to 11.8v according to the volt reading on the helios. So I'd have to say SUCCESS!!! With this setup I no longer need to carry a super heavy transformer.

I'm off on a trip for work next week and will work on it more next weekend. I started up a new gallery.

what are you going to use as grill guards for the cars to rest on, if anything? you could find some welded wire mesh or something like that. the typ grill guards are raised up and would likley make the cars rest akwardly?

i was fortunate enough that the ribs on the lids were placed nearly perfect for acting as curbs to keep the car placed perfectly on the lids. i also made the slots a bit more narrow where wheels might rest so that the car is never bottoming out on the lid.

Glad you asked ;) I'm going to some how mount some mesh about 1/4" from the bottom like a screen. For now though it cools quite well even with just 2 fans and the two chargers. I need to get a unibit or hole saw and cut holes just below the chargers. If I can score some good mesh I'll mount fans under each charger. In the end all you'll see is the cars and chargers sitting on the mesh.

I'm also going to mount the power switch, power LED, and 120mm fan on the front flip down door. When I need to gain access to the power strip it will be within easy access. This will put less holes in the box keeping its integrity.

the surround sound is quite small, and runs off of a 12V power supply, so it could be used. I have been thinking of taking it to the track to play some tunes on. Besides that, it would make the box more multi-purpose. Like I could take it anywhere, and just plug into wall or car battery and have tunes without the higher drain of the car stereo.

But like arch said, its just fun talk, I would need a much bigger pitbox for all that, wouldnt want anything to overheat :D

Well that depends on how much you think you'll need to bring for 1-2 cars. The cooling fans don't take any room so you can easily set two mini-z's in there. The open area on the right where the tools are is dedicated to tools. The small area next to the power supply is for the cord. And the open bay on the right will fit 4 small boxes snuggly. The transmitter will not fit and will need to go in a seperate bag. I'm going to get my hands on some foam rubber and line the top with it so the tools and cars don't move when transporting. The top of the box also has small bays for anything else small you may wish to carry.

For the sake of air travel the box will not exceed the maxium dimensions. The tx will just have to be put in a bag and layed in the suitcase. Everything will be packed in a locked suitcase anyway so it doesn't grow legs and walk away.

If I was say traveling to arch2b's house by car I wouldn't really need much more what I have today which is the tub for the cars and tx's and the cooling, charging, tool box.

I found that I've not used everything in my kit so this has forced me to focus more on what I need for repairs and short term fixes. When we raced in Stafford I brought quite a bit and only really used the chargers. I did make some changes here and there but I was always well prepared and inspected the car thoroughly before transporting. You should always go to the track ready to race.


Sorry for the long post. Lastly It's 220v here in the UK and having 120v chargers I needed to bring a transformer and a 110v power strip. That alone was a pita to lug around so this has made it 100 times better. It's plug and play. :p

ok, i talked to spoon about this but i need to wire the 120mm intake fan to turn on when either of the two cooling fan stations are turned on. these have 3 pin switches.

how can i wire the 120mm intake fan to do this? spoon mentioned using diodes to keep the positive power from feeding back to another station when one is turned on.

excuse the poor diagram attached.

basically, i need the intake fan to turn on when one or both of the cooling fans is turned on. this means i need to draw power from both cooling fans so that when one is turned on, it will turn on the intake fan. what i need to prevent is when that happens, the power can not go back to the other cooling fan on the line which is turned off.

These should work. Just solder then inline with the positive supply. I think you want the end with the line on it facing the 120mm fan.

after talking to byebye i will be making some adapter cords for my chargers so that i can plug them into my 12v jacks in my pitbox so that i don't have to carry around the bulky wall plugs.

can someone tell me which ends of the dc jack is positive and negative? i bought some from rs but it did not have any diagrams or anything

I think typically the longer terminal on the hidden side is negative. You can check if you have a multimeter. Just take a jack that is already connected to the wall and check the voltage. I believe if you put the red lead in the center of the plug and the black probe on the outside you should get a positive voltage, if it's backwards you'll get a negative voltage. Once you figure out the correct polarity set your multimeter on Ohms to check continuity between the side that will be exposed (plugged in) and the side that the wires will be soldered to.

If you need a better description, let me know, I can work something up for you.

By the way, I made some slight modifications to my box and I think I am finally done. I could do more but I am pretty happy with the whole thing. The only bit of flare I might go for is some LED fans if I can find them cheap...

My fans and grills are 92mm but I might be able to fit an 80 mm on my car cooler. If you don't find a use for it by then, I'll pick it up at the next GTG.

You can buy a multimeter pretty cheap at RS but I am sure I have some plugs and jacks that I can check for you when I get back into town. I am in Jersey now but if you remind me, it will only take me a minute or two. I'll be back in town Thursday or Friday, shoot me an email and I'll set you up.

The negative is the outside and the positive is the inside of the plug on the adapter. The color scheme on the wiring is black/white stripe is positive and solid black is negative.

I'm guessing you don't have a multi meter :confused: ? I just bought one here for my pitbox. I think it was in the last updates pics of my box. Anyway you can tone it with ohms. Let us know if you got it;)

i just finished installing the 120mm intake fan.
http://mini-zracer.com/mini-zgallery/data/966/medium/IMG_0883.JPG

i have insulated quick disconnects attached and have already run the wire to both the switches and general ground wire.

i had to run some more holes thru the ribs for the intake fan
http://mini-zracer.com/mini-zgallery/data/966/medium/IMG_0882.JPG

i got around to removing all the deans plugs and installed the insulated quick disconnects to the rest of the wire sets as well.
http://mini-zracer.com/mini-zgallery/data/966/medium/IMG_0884.JPG

so, both 12v jacks are live, both cooling stations work, intake fan is installed and prewired. dummy me ran out of diconnects though so completeing the work will have to wait till a quick run to rs tomorrow. oh, i need to pick up those diodes as well to get the power flow right for the intake fan.

next will be to install some cheap and small speakers similar to what byebye did for his so i can plug in my zune and listen to some music or watch some initial d :)

oh, since i ditch the charger adpaters, the spake soaked up by the intake fan is taken care of. all i have to do is solder on the dc plugs to the wire sets i made for the chargers. i made 2 sets. this should be enough to run one of the chargers and whatever else i need like the large scale stuff via the peak charger or the Lit or epoch after i install dc jacks into the base chargers for them.

Yeah search Ebay for cold heat. I looked just briefly(I got one for Christmas) and there is some that are DC, 4aa's with interchangable tips.

Now what are the chances your gonna need a DC soldering iron? I mean the pit box needs a plug. you're best best is to purchase a cheapo soldering iron and a fine tip and carry that.

I like the coldheat. It's perfect for me with automotive work since I park on the street and there is no plugs around. Can you do a FET upgrade? NO WAY! But it's good for tinning and some fine work where wires may have come loose.

The speakers do have their own headphones jack you just plug in and turn the speakers on.

@Ninja-Yeah I though about maybe wiring up a single receptacle. Definately doable but may not be the safest setup if not done by a trained electrician.

since my local rs is on the crappy side re: inventory for anything, i ordered the diodes, dc jacks, and stuff to complete the modified pitbox project.

i'm not certain what will happen with the speakers yet. i may end up providing a jack to plug them in for power via byebye's usb 5v conversion. as is, i don't see much space left for adding them in a manner to keep the lid closed and not impeed on storage space. as it is, i had to cut out the chargers power adapters. any more restrictions limit effectivness of its ability to be the storage bin it is intended to be. as much fun as it is, i still need it to be functional.

i must say, this project has been some of the funnest stuff i've done in a long time. :) it's cool to take a bunch of found objects and make something unique out of them. i realize that many will see this project as trivial and pointless but to me it's abotu rekindeling the love to mod things that i've not had the chance to do in a long time. my days of spending hours on making cutoms parts for cars/trucks are just about gone for good so getting the short breaks to do this has been a real treat.

i will end up with something that is unique and fun. turns out it will be very functional as well.

Multicar cooling station perhaps?

If you need some small 12V power supplies let me know. I have one that I pulled out of a small standalone disk drive that I think will deliver 2 amps. May be enough if you are just running fans. It's a little bigger than a candybar.

The fans draw a total of 1.6 amps, and we're not quite done connecting stuff to it :D

The front two fans draw air in, and the back six fans blow out. They're mounted to a steel mesh. I built three paper prototypes to make sure I got the measurements and angles right before I cut the steel panel. After cutting we folded, and after folding we drilled and sawed holes. Painted. Mounted fans and hardware, soldered the bread board and the molex connector and then dressed it all up in the wire loom.

No, not particularly. Certainly not for one car, but three cars fit on the rack quite nicely, and it moves a lot of air. It's not an exercise in practicality or efficiency though.

I had to lengthen the wires on the green light to reach the power supply near the blue light. They're powered by the same unit and can be sound modulated once there's a sound source (stage 3!).

The great thing about this box is the split hinges. The lid has just about as much space as the bottom section.

I make it sound like I did a lot, but really the whole rig is Soundwave's project. I just helped with some of the technical aspects.

I needed a new pit box as my old one just wasn't up to the task any more. I was going to build a gig box similar to Soundwaves, but from scratch. I found all the needed materials, but it was going to be expensive. Then I found Vaultz (http://www.ideastreamproducts.com/vaultz/Vhome.html). It wasn't a perfect solution. I couldn't customize my dimensions, but it had the things I wanted. Combination lock, solid construction, felt interior, good price. So I got the Letter/Legal File Chest (http://www.ideastreamproducts.com/vaultz/LtrChest.html). The only thing missing is a top handle, which I will add soon.

I wanted to keep the contents organized and secure. I wanted to condense all my electronics to a single plug. And I wanted to keep the mods as flexible as possible. To that end, with the exception of the plug, everything in the box is attached by velcro (and very secure!) and can be undone or moved any time I need to. The partitions are 3/16" plywood covered in foam and felt. All the plugs, wall warts, etc are hidden under the fan rack. Still to come will be a double-decker box for cars and bodies on the right. Dry erase board for jotting down notes/times, etc.

Total cost of the box is less than $100, not including the chargers (yeah, they're cheap chargers anyway, I'll replace them soon).

the power strip was a bit more expensive because i wanted to stick with stanley, the manufacturer of the toolbox. i bolted this to the back of the box. the idea is to unravel the cord where ever i am with the 10' cord and plug my chargers, etc. all into my power strip right on my box.
