The commented device is a signal generator which delivers a waveform at a certain freq. Knowing the waveform used, and the frequency at which it is delivered, I think it could be done by Spooky for sure.
Regarding the resistors, I also think that using the right resistor, you can set the output current into the desired range. With the help of a multitester capable of reading microamps, you can try several resistors until the desired amperage is reached.
