I've finally made some 'real' hardware for QPID. I created a custom Arduino shield that includes all of the special hardware and connectors required by QPID. It includes connectors for the temperature probes, a connector and power transistor for the fan, and seven SMT LEDs on the foil side that will serve as indicator lights.
I used software provided by ExpressPCB.com to design the board and match the Arduino dimensions and header layout. It was then printed on a transparency and etched via a positive-resist process. Homemade PCBs aren't the best, but they're cheap and easy to make for prototypes like this. And it sure beats a breadboard.
Hi Mark....Any plans to release the design for the PCB?
ReplyDeleteSure, I can probably do that. :-) Please give me a few days since I'll also need to prepare a detailed components list, especially for the connectors that have a very specific footprint.
ReplyDeleteAwesome Thanks Mark.
ReplyDeleteThis design is perfect. I've been looking for a solution like this, but I would have never thought of this. Did you ever post the design of the PCB? I would love to see how you did it.
ReplyDeleteThanks for the ideas.
Big T., sorry for taking soooo long to post the PCB details, just not enough hours in a day. I'm working on it as we speak, and in a day or two I'll post a PDF with the foil pattern, component layouts, and parts list. :-)
ReplyDeleteDone (see the post for Feb 8)
ReplyDeleteHi! Can You post, the exspresspcb, pcb file, I want to create a custom shield, for camera remote, but I don't have the exact measurements for the pinouts, thanks rec
