You can make one! If you have a pair (or single) high impedance headphone set, you could use it, with a small signal diode and a capacitor for safety as a signal tracer. You will need to do some measurments in order for the assembly to fit inside the New pen probe. You can use the barrel of a BIC ink pen or other brand that has no metal. Its all plastic, which would insulate you from shock. If you have an old RS232 plug, there are a number of pins that ...
