PW 1986 High Impedance MOSFET Voltmeter

[Mark Hennessy]

Looks really good Joe!!!

Given the very high impedances on that circuit, it might be worth spacing the Veroboard up from the bottom of the case - looks a bit close on the photo (sorry if that's stating the obvious). Old Bicc biros cut down make good spacers for the cash-poor, time-rich

I have a small collection of moving-coil meters, and keep thinking that I really must do something with them. One day...
