HOW TO – Make a pogo pin testing jig. For more complicated projects, you may need to have a longer testing procedure in which case we can make multi-step testers that also keep the PCB held down with little ears! The plastic pieces hold down the PCB against the pogo bed.
This tester, when used with a little batch script, performs the following test:
Reprograms the board’s fuses and flash with a bootloader (via the ISP port). For this part we’re using the Arduino as an ISP programmer (there’s a sketch that does this)
The computer then bootloads (via USB) a pin-by-pin testing program
Once the board indicates the test completed, the computer erases the testing program

Nice take on a bed-of-nails test fixture. Any plans for a flying probe (woodpecker) tester?
“They also fit snugly into ‘standard’ 0.35″ (0.9mm) drill holes so they are easy to insert and stand up straight. ”
Should read 0.035″, missing zero.
