I'm considering cleaning up my RFID door lock electronics that reads my chip and opens the door. Right now the electronics is soldered together on a project board. It'd be nice to do a printed circuit board, use surface mount components, a better power supply, etc.
It'll take a bit of time and $$$, so it's really not worth it to make just a few (front & back doors, some spares). I'm wondering if anyone would be interested in purchasing at my cost. Since the volume is so low, even, "at cost" would be on the order of $50 or more.
