my 1st scratch case made july 2008 (finding my feet)
Air Cube prototype (fin jan 2009) (still finding my feet)
Air Cube v2 now with added cpc stack (fin aug 2010) (getting better)
Project Stealthlow (fin sep 2011) (much improvement)
Lean and Green - modular dual PC scratch build - Paused
I got this candy mold from eBay for $2
I had some of this casting resin leftover from a different project
I mixed 1oz of resin and 1oz of hardener, and it was enough to fill all 8 cavities. I only needed 2, but I did all 8 in case I screwed one or two up during the removal process.
Two days later I removed them from the mold. It's a good thing I made all 8, as they were tough to remove and I only ended up with 4 usable pieces. Yes, even that broken one will do, you'll see why in a sec. These just need another day or two to harden, then I'll do the final trimming and filing and painting.
Next I had a pair of these green NGK spark plug boots. But they'll be of no use to me in the state that they're in. So off to the band saw!
Now this is why that broken one doesn't matter. These will sit at the back of the case (see the SketchUp models in the first post). I'll mill out the center of the plugs, and 3mm blue LEDs will be installed. The wiring will be run up the plug and cap and out the wire end of the caps, and over to my LED blinky kit from John at PCBoard.ca.
Now the LED blinky kit blinks much too slow for these to look like real plugs firing, so I did some swapping of capacitors and resistors until I got the blink rate just right.
Video if the standard configuration:
And soldered together:
It's kinda hard to tell because of the frame rate of the camera, but it looks sweet.
Next I disassembled the Cooler Master V6GT that I got from CJ. The LED effects that come with it are red, blue, purple, or off. This won't do now will it?
So I took out the control board and hot-glued in a 5mm green LED
I'm also going to add 4 5mm green LEDs to the front side fan on the cooler. I'm currently waiting on a shipment of 5mm and 3mm green LEDs
That's all for now!
send the plugs out to me and I can make them look real,...
Nice! Hmm, those spark plug candy moulds are tempting....if nothing else to confuse people at parties.
sounds good. I've got to go look at a guy's snowmobile after work, so I'm not sure when I'll be free. I'll probably end up going over there and pulling the carbs off and bringing them back to my hosue and cleaning them. want me to give you a call when I'm home?
sweet! That's the same epoxy stuff I used to cast a few parts on the sandcrawler. I found it hardens almost completely in about 24 hours. Did you use a mold release of some kind? They should have come out pretty cleanly if you did (although I used a latex mold rather than plastic, and was able to peel the mold off my casts). I also used a resin spray on the casts after they came out to ensure that their outer surfaces were nice and hard.
I didn't truly appreciate what a nice case this is until I happened to see one in Fry's this evening. Looks awesome, even without doing anything to it! Your mod should be some pretty awesome improvements.
