Fresh hacks every day
Just a few weeks ago we were wondering if we’d try to build our own prosthesis if we were ever to lose a limb. This pair of hacks answers that query with a resounding “YES!”.
To the right is a replacement pointer finger. The missing digit took the first two knuckles with it, but there’s enough left to easily … Read the rest
Hackaday reader [JumperOne] was in need of a logic probe that he could use to reliably test some tiny .5mm pitch IC pins. The probe that came with his oscilloscope was a bit too big and not near sharp enough to do the job, but he figured that a syringe might do the trick nicely.
