Bus Pirate week, day 5 – measure a capacitor and parts unboxing

This week is dedicated to Bus Pirate development. Today we hacked the Bus Pirate to do crude capacitor measurement. You could use any microcontroller to do this, but one nice thing about the PIC24FJ is that it has a 32bit timer to measure large value capacitors. In the video:

    It would be great make Inductance measurements, from a Microchip application note I read that it could be done using the CTMU, could be a great project.

    You beat me to it! I was going to do a bus pirate C tester this week-end!

    Little suggestion, you can put a fixed capacitor on the board, so you can make always a calibration, this way you can compensate errors on timers or voltage references, and you don’t need to put any constant inside the code.

    Hi Jan

    Looks like you already have gotten your xmas presents.
    What could be better than a big box full of electronic components and some pcbs,…
