DIY Component Tester – Transistor, Capacitor, Inductor, Resistor Meter

at 8:05 pm. Filed under Cool Gadgets, DIY Hacks


If you are looking for a DIY meter project have a look at this DIY Component Tester (translated),  it tests Transistors, Capacitors, Inductors and Resistors. It is AVR based and is very flexible, in most cases you can just jam in a device and press the button to analyze the device.

“Automatic detection of NPN and PNP transistors, N-and P-channel MOSFETs, diodes, thyristors, inductors, triacs, resistors and capacitors.
Measure ESR with a resolution of about 0.01 ohms
Automatic calculation and display of the pins of the component under test
Detection and display of protection diodes for transistors and MOSFETs
Determination of the gain and the base-emitter forward voltage at transistors
Measuring the gate threshold voltage and gate capacitance of MOSFET
Self calibration process to improve accuracy”

    hi there,

    So i’ve seen it work and wow man, makes me greedy.
    Is there a schematic/ pcb design / component list??
