I have acquired a number of old Fluke 8050a bench meters, Curse you EEVblog and EBay. I wanted to upgrade the display from the original LCD display to something that would look cool sitting on my bench. Here is a project that showed how good the meter would look with an LED upgrade. http://lous.home.xs4all.nl/fluke/Fluke8050Asite.html
My project uses a microcontroller that reads the info from the Fluke 8050A and displays it on a cheap 2.2" 320x240 lcd display. The display is an SPI controlled ILI9341 display available on EBay for less than $7. A bigger display won't fit. I chose to use a PIC18F46K22 as the micro. It has enough pins, operates at 5V, runs fast (64 MHz), and available from Digikey.
All of the points that I wish to access are available directly on the main 40 pin DIP processor of the FLUKE 8050A. I simply piggy backed the PIC18F46K22 on to the 40 pin DIP, some pins had to be angled. The pins that weren't connecting to the Fluke were bent up to be soldered on to a proto board.
Stuff I'd like to add:
