Restore Multimeter Display with OLED

Recommended Posts

So I didn't know where to post this but I thought some might find this interesting.  Someone had a HP 34401 bench top multimeter that was working fine, but had a display that was fading and was hard to read.  So they probed around the display communication, saw that it was SPI, and then made a device that received the SPI data and put it on a new OLED display.  They then fitted all of this inside the old unit so it looks as good as new.

It makes me want to try to find some scrap hardware on ebay and see if I can repair it.  Of course I don't really need another random piece of half broken equipment in my office.
