It worked decently well on the breadboard, had some issues with connections.
we etched a prototype board, which works fantastically, except for some odd bugs we have not yet worked out.
Something is latching and causing the temperature control to stop working and heat to the maximum possible temperature. not sure if its software bug or the mosfet or opamp giving us issues.
I have been on the lookout for something similar for a while now, here is one I attempted to build:
very similar to the one you have posted on the early pages here, but I got stuck, there is only a hex file avail, and so I could not do any debugging.. anyways
what has become of this? can you share?
Absolutely. this project was always intended to be freely available, we thought about building completed units and selling those or partially assembled or kits or something, but I firmly believe that Open source is how everything should be.
If you have the ambition to put it together yourself, you should always be able to do so. Thats why I run Linux.
I'll find the arduino files and kicad schematics/board designs.
Also, er0ck, I apoligize greatly for not noticing your post earlier. I have removed the approval restrictions on your account.
EDIT: I have attached the Kicad schematics, board designs, and arduino source. I'm not sure what kind of license I'd say its under. If you make money off my designs then I'd like a share, I would prefer you share any improvement with myself and everyone else though.
there is 3 designs enclosed.
solder - 2.brd is my first design, had some minor issues that caused problems.
solder.brd is my brothers updated design that we have a *mostly* working etch of.
soldermk2.brd is my brothers double sided design that would be used if we panelized and ordered a batch of pcbs professionally.
