I wanted to do something with OLEDs (organic LEDs) as I have never used any of them and I wanted to find out more. After some research it seems that they are tiny display that are quite bright. So, after a while thinking about how they could be used to make a test instrument I decided why do make small digital volt meter (TinyDVM). Existing DVM s are cheap and accurate but it seemed worth a go at making a smaller one. I want to use Arduino and I have a 3D printer so I will try to make a completed packaged up small DVM and I will see how small and how packaged I can make it.
