I've lost my URL for an expanded scale voltmeter. The only parts used in the
circuit were two LM78LXX regulator ICs.
The sum of the regulator voltages is picked to equal the minimum scale
reading. Then, the minimum
plus the voltmeter were the maximum scale reading.
Example: An LM78L05 and a LM78L08 with a 6 volt meter would have 0 = 13V
and FS = 19V.
I thought it was EDN but searched the site and didn't find it.
Anybody have it?
Thanks, Mike
