You can get some nice little heatsinks from EUVL

Thanks! I didn't know I could buy these from EUVLs site... will be using this for my next builds.

I'm getting severe builditis waiting for chassis and power supply pcbs. Someone please send me something to solder.

If you'r getting antsy, and you have the materials. take a shot at DIYing your PS PCBs. I used some auto body repair leftovers to make fiberglass boards and just sprayed them with flat black paint. Could have used perfboard but didn't like the appearance. I covered the cloth/resin/bondo sandwitch with Saranwrap and clamped it between two pieces of plywood then trimmed the excess. I'm making another set (copy of Peter Danilels board) for a Burning Amp project this weekend. Beats waiting fro the mailman.

I've used plexiglass before. Obviously care is needed in soldering but it can look cool. Your board certainly IS cool Bob.

Hey U, good to hear from you. It's a good economical method particularly if you have the stuff around the house. If not, kits like these from local auto stores can make a lot of custom PCB/boards.

Fiberglass Kit.

You know what? I bet the fiberglass resin is all you need. Just put down some silicone (was just talking about this in another thread) in a box and then push maybe a board into the silicone. Then let the silicone harden, remove the board, pour resin into the mold and wait an hour. Voila! A nice flat board.

I'd put at least some thin webbing in the mix. Resin alone can crack like peanut brittle. If you make it thick enough that may not be necessary,

Thought I better show the bottom. I use thin (1/32") copper from the craft/hobby store for bus work. You can cut it with scissors to any shape/size you need.

I say bypass the messy part and just cut up a corvette or an old canoe.

Being a FORD man, I never could figure out a good use for a Vette. Thanks,

 

[billyk]

Wow Bob, that's some outstanding work. Nicely done!

Thanks Bill,

Might consider coating the bottoms with something to eliminate a shock hazard, but haven't needed to so far.

For those who might be interested in the PCB construction process, here is a link to a new thread on the subject.

My Aleph P1.7

Finally finished

An externally hosted image should be here but it was not working when we last tested it.

Goodness me! That does look good. So how about a shot of the internals?

 

[R-K Rønningstad]

Oh what a beauty!

 

[mat1976]

nice work Secan, very nice.
does the inside look just as good?
