Making a servo tester using an Attiny85 micro chip, Attiny45 also works for this project. This diy servo tester is as good as ...

Check out this Arduino-based electronic component tester. The device is intended to give a simple way to test transistors, resistors, capacitors, diodes and MOSFETs, and such like. The Arduino tester ...

The tester only uses 24V, but for the projects he’s building, that’s close to the operation in the real circuits. He does have a traditional tube tester, but it uses 100s of volts which is a ...

The meter has a measurement range of 0.1 hertz to 30 hertz for capacitors having values ranging fom 0.47 to 2,200 µF.

For dual-polarity tests, two diodes should be used back to back in parallel. Figure 3. Alternative test circuit that incorporates a small-signal diode Test Hardware Considerations A variety of ...
