Syringe logic probe, revision 2


[Travis Goodspeed] has updated his syringe based logic probe that we covered earlier. Instead of soldering to the outside, he’s using silver wire shoved into the core of the needle. A nice side benefit is the safety cap now fits. Inside the syringe are two LEDs that indicate current direction. The sharp needle makes it a lot easier to hit small traces.
