Useful cheap small tester...

I'll build it into a little box with ......

Perhaps you could make a batch while you're at it

Huh, not enough hours in the day Alan - we hardly ever seem to be at home!

The gestation period for things on my 'to do' list gets longer each year. Back in 1985 when I was still interested in amateur radio, I built a PW FET Dip Oscillator, and the same author designed a high impedance MOSFET Voltmeter in Dec 1986 PW which I thought would be useful to peak up tuned circuits without loading the circuit. So, I copied the article and made a PCB. I then looked out for a 100uA meter movement as the 2" square one used in the design was in my view far too small. The years went by, then eventually I saw an excellent Ernest Turner meter 5" x 4" at a rally for just £1.00.

So, the PCB and meter were put aside with the article, and I recently decided that I'd make up the PCB and make a little comb-jointed box in which to build the meter. That's as far as it's got - now the summer is here, other priorities will almost certainly take over, so it will most likely become a 'winter project'. I've utterly lost interest in amateur radio, so really I have little need for the meter - it's just another example of my urge to build little homebrew projects - a bug that bit me way back in the late 1940s as a schoolboy and has never really waned since.

Rather than take this thread off topic, I'll post a few pics on progress to date (such as it is), in a thread in the homebrew section.
