PCB design job
(1/1)
rhb:
I'd like to commission an OSHW PCB layout for Chris Trask's crystal tester:
https://www.moarlabs.com/moarlabs/resources/subjects/circuits/analog%20circuits/oscillators/oscillators%20-%20crystal/crystal%20test%20set%201.pdf
I want to make a few minor changes such as the use of a MOSFET switch and a GPIB interface based on the AR488 to flip the MOSFET switch. This will allow me to use my HP 5386A frequency counter to measure crystals and fill out a spreadsheet with me only numbering and inserting crystals on cue.
Pleased send me a PM if you're interested.

rhb:
have filled this.
Sniper1:
Interesting circuit.
If you dont have any offers i can try to slowly do it (not sure how much free time i will have but ill do it reasonably fast after i understand how it works , in order that i know how to properly chose the FETs
rhb:
I've completely abandoned this method in favor of an HP 8593A for ease of programming.
It is very interesting and I spent a good deal of time playing with Butler oscillator.
