COMA+ is PIC32-based instrument that can be used as calculator, oscilloscope, multimeter, analyzer and more. Ganzziani, project designer, said that one important goal project is to make the instrument low cost, so the capabilities of the PIC32 are being maximized. Since the device is going to be handheld, the power consumption needs to be [...]

ESR (equivalent series resistance) is one of the characteristics that define the performance of an electrolytic capacitor. Low ESR is highly desirable in a capacitor as any ripple current through the capacitor causes the capacitor to heat up due to the resistive loses. Typical capacitor checker measures the capacity of the test capacitor. Some [...]

AS7010 STmeter is PIC16F877-based project which is designed to provide a handheld installation tool to assist in the set-up and configuration of wireless DSL subscriber terminals operating in a point to multi-point configuration. The device allows the majority of installations to be carried out without the need for a laptop computer. This easy to use [...]

This simple AVR ATtiny2313-based LAN tester allows you to check the type of LAN cables (straight or cross) and to test whether LAN cable is broken or not. The project has 8 outputs. Each one of them produces a pulse successively and only one output can be high at any time.
