Dremels, Hacksaws, and the occasional spade bit.

That's what I use. ABS is easy to work with!

My dremel broke, so I have been melting a hole somewhere inside the plastic that is to be cut, then using my hacksaw to cut out the piece i need. My only problem is that hacksawing turns really sloppy after a bit, and it's hard to keep it neat. I end up with rough edges and amateur looking cuts (fit for the amateur me I guess :P). I heard using a propane soldering iron with a hot knife bit is OK, but I doubt the knife bit would last very long.

You could see if heating a hot wire might work. ABS's melting point is pretty low.

I'm usually able to clean up any nasty edges with a knife, but I do know that some soldering irons come with a hot knife tip attachment..

any update on this? I've recently gotten a few TECs. 40x40mm and 30x30mm and I was looking for some info to make a project a lot like yours.

I've got the PCB planed out, somewhat.

I'm waiting on an arduino, then I can put everything together.

Default Re: TEC cooled Diode testing station, suggestions?

So I'm kinda resurrecting this thread from the dead because I actually have it all good to go now and ready to build by the end of may.

I'm taking an ECE class at the university for the arduino, so that's going to be in there for sure. I found some ME's that can machine some heatsinks for the TEC assembly, so a proof-of-concept will be ready soon.

Any help is still appreciated!

Regards,

Amk
