Krow's TEC Controller - Build Log - Page 5

post #41 of 116
Thread Starter 
32A is the maximum design level. I don't think PCIe 6 pins can handle more than that safely. The current prototype gets really toasty in the MOSFETs but it's still within operating temperatures. Future redesigns will be using different MOSFETs that manage current and heat a lot better. Shouldn't even need cooling on them when done and I'll just be using less, but that's revision 2.

Sounds good man, can't wait to see some finished products.

Hopefully you take your time - I added another car to the stable so i'm on the Ramen Diet until I finish a few things it needs laughingsmiley.gif

Once I get my hands on that, I am going to etch my PCBs and do the final testing of the prototype. Once that is done, it's off to the guy who wanted it. After that, I refine the design, test a little more to make sure it still works, and then it's off to the online store with it biggrin.gif

I don't think I'll be making the physical portions of the project Open Source, only the code; and I'm still not 100% decided, but I'm getting closer and closer to thinking that's the way to go.

Price isn't decided yet, but it definitely shouldn't bankrupt you, unless yer trying to do TEC on a shoe string budget in which case, you might as well just insulate. And it will come with the ability to program it yourself if you decide that the default firmware isn't good enough.

Once this is all complete, it's on to producing my own TEC Blocks. biggrin.gif Might do chiller designs too but they take up alot of space, it's hard to keep it all inside the computer case.

dont bother with the dremel drill press. I got one thrown in when i bought my dremel and it was horrible, it kept twisting a bit when you pull it down so you couldnt even drill a straight hole...

Any chance these will be ready for the Holidays? biggrin.gif

It's possible, I just need to knock out the PCB and drive bay case for this prototype. I have pretty much all the parts, just finishing up PCB design and then etching commences. Also have to fix my laser printer up with a print server but that takes no time.

My prototype should be ready next week.

My plan is to modify the Cosmos 2 front panel so that I can control the peltiers. That cosmos 2 panel is useless.
