Ugly Probe

When my active probe have burned I decided not to repair it because high cost of its OPA653 but made new one with cheap BF998 dual-gate MOSFET

I chose the design of David Jewsbury

I already had some of the parts, and I bought the rest. Everything cost about $1.

Since I am very lazy, I did not order boards in China or etching them, but simply scratched the foil with a knife.

Overall loss is approximately 20dB so you don’t need attenuator.
