I have some different boards and parts that are taking up space, most non-working and can be had for free plus shipping if you're looking to hone your soldering skills or scavenge parts; all prices not including shipping:
8-Driver PCB from STTNG (A-16100) - has been repaired twice (Q1 replaced both times), some traces lifted at Q1, currently not working - FREE
Eddy Sensor PCB from RS (A-18543-2) - started registering hits to the bulldozer all the time, the pot no longer works to adjust sensitivity - FREE
