    Using an ADC + Teensy or a DPM with BCD output + Teensy

    I started thinking more about an analogue solution: the original meter is a 2 365Ω load, and to make the numbers pretty I could take a differential measurement over a 1 024Ω 'resistor.' You might be thinking 'Ack! a 1.024kΩ resistor!? Where would you find such a thing?!' The trick here is to...

    Using an ADC + Teensy or a DPM with BCD output + Teensy

    Ok, the coil resistance on the original meter is 2365Ω, and at full scale reading of 200µA, 0.473V (473mV) would be across the coil. If I wanted 0.000 100 V (100µV) resolution, that would require a minimum of 4 730 'steps,' which is greater than a 12-bit ADC can provide (4096). The Teensy 3.0...

    Using an ADC + Teensy or a DPM with BCD output + Teensy

    Using just a Teensy, an ADC + Teensy, or a DPM with BCD output + Teensy Hi, all! I've got a personal project where I want to replace an analogue meter with a 'smart' display--the idea is a bit of a feature creep in and of itself, when I was looking at swapping in an Analog Devices AD2010 (3.5...
