I recently got an old variac and started looking for a modern volts/amps meter. There are cheap panel meters around but they are very limited. The $20 Zotek (ZOYI, Aneng, etc...) meters are so much better!
So I thought of basically making a panel meter from a cheap DMM.
The first issue seems to be detaching an LCD and making a "display cable". But I am sure somebody has already tried that.

Any hints?
I could not find any zebra adapters, it will probably require a custom PCB. Is it as easy as it sounds?
Did anybody try making a custom LCD zebra strip mount? Are there any tricks that I should better know before trying to design something myself?
(Like should the display PCB match the full size of the LCD or is it enough to cover only the contacts for mechanical rigidity? How much do I need to compress the zebra strip?)
