content: I have some extra unpopulated PCBs, some because I screwed up the design and some because I ordered more than I need (e.g. ITeadStudio sends you 10 PCBs cheap, even if you only need one).Is there anything fun or craft-y to do with these boards, or should I just throw them out?Thanks,Bob

content: I actually find that dead chips are better for keyrings. I'm using a motherboard main chipset and my girlfriend has PIC16F877 with 'accidentally exposed silicon' (mains short ;p )I use unneeded pcb's for making support structures for other devices, custom size washers, spray paint stencils to name a few ;p

content: Quote from: poorchava on December 08, 2012, 08:55:16 amHuh, I realized that my current keyring is about 25 years old!It's made with the ULA (a DIP 40 pins chip) of my first computer, a ZX81, after it did not survive an extensive tweaking of the board...
