Hi Ian.M,
there is physical space available to make a "thin" pcb that would fit in place of the original VFD.
I am looking for parts right now, but I have a few concerns:
- Thickness, probably do-able with SMD displays;
- The huge amount of extra indicators, like AC, DC, Hz, (m)A, V, dB, etc. (Thinking of using LED bars with a silk-screen in front)
My first test will be something like 2x a normal 5digit common cathode 0.36" display, with a separate digit in front of this for the minus-sign.
I had a look at how to do the secondary display: In the original VFD they use something like a (but not really) 14-segment display in three digit´s, but I could not find any application for these extra segments, so I just think of leaving them out. (I´ll use 7-segments, so, just numbers there, and simple characters like ´print´)
Keep you posted about any progress,
Un saludo,
