It all has to start somewhere.

A project log for Fiber Optic Isolated Voltage Probe

Use cheap plastic fiber optics to make a useful Isolated Voltage probe for an oscilloscope or other instrument.

Well, I have a first cut at the probe schematic. Ideally, the probe will have 50-80MHz bandwidth, without horrible distortion and with less noise that an oscilloscope. First time I've built a circuit with a discrete input amplifier. Goal is to get a PCB laid out this week, and get it sent out with other work PCBs.
