  This project is a NiCad-NiMh Battery Monitor based on LM3914 IC Description The simple project can be used as test gear. Its easy way to monitor the battery voltages, especially dry cell, NICAD, NIMH, supply up to 1.5 Voltage. Battery Monitor range 0.15V to 1.5V. The...

  This project is an advanced LCR meter based on PIC16F690 microcontroller. Description After finishing my last project - "Simple LC meter", there were some discussions in the forum I am a member of, that ability to measure electrolytic capacitors would be very useful in...

  This project is a simple LC meter based on PIC16F682A mcu. Description Here is another piece of laboratory equipment - LC meter. This type of meter, especially L meter is hard to find in cheap commercial multimeters. Schematic of this one came from this web...

  This project is a simple Thermocouple K-type amplifier based on AD595 IC. This amplifier converts the thermocouple output voltage (uV) to 10mV/C. This voltage can be easily further converted by an ADC of any microcontroller. Description AD595 Thermocouple Type-K Amplifier...

  This project is a simple LED tester and LED polarity checker. It can be used to check 1206, 0805, 0603 and 5mm LEDs. All parts are readily available and they are very cheap. Description Usage is very simple. Just press the tack switch to first check the battery is good....

This project is an accelerometer data acquisition system for automotive suspension analysis. In other words it's a low frequency spectrum analyzer based on Lanchpad TIVA Series from Texas Semiconductors. Description It' s a spectrum analyzer for mechanical frequencies (max. 50...

  TraId is a simple transistor tester and pinout identifier. It is able to test bipolar transistors as well as N-mosfet and P-mosfet. Result are displayed using LEDs driven by a PIC16LF1503 microcontroller. Description The board is using a 14 pin PIC16LF1503 (less than a...

Introduction This project describes how to make a digital voltmeter using a PIC microcontroller. A HD44780 based character LCD is used to display the measured voltage. The PIC microcontroller used in this project is PIC16F688 that has 12 I/O pins out of which 8 can serve as analog...
