This project describes how to make a digital oscilloscope using an Atmega32 microcontroller and a graphics LCD. The GLCD used has 64*128 pixel dots (GDM12864A with KS0108 processor) and the AVR runs at 16 MHz using an external crystal oscillator. To enhance the speed further, it uses an external A/D converter chip, ADC0820. The sampling

This is an interesting voltmeter project that display the measured voltage on a TV screen, in giant digits as well as with analog bar. It also records the maximum and minimum values of measurements. The project was built by Alberto Ricci Bitti and was published in the May 1999 issue of Elektor Electonics. Read

LC Meter: Schematic Source code This is the project I am currently working on (2010-01-23). The LC meter is based on Elmcie or Elsie and other similar LC meters. This project is in a very early prototype stage and is at the moment only capable of measuring inductors. Even though I have build the first prototype on a breadboard the

Designing a professional digital oscilloscope is a pretty complex task wich makes them also pretty expensive. Therefore I concluded it’s nothing more than a daydream to design one of those. It’s far more realistic to limit the design of this instrument to something a bit more realistic. If you connect something like the JYE Tech Oscilloscopeto

The benefit using thermocouple sensor for measure temperature is it has wide range measurement (-200 °C to +1350 °C / -328 °F to +2462 °F range for Type K), inexpensive, interchangeable, and is supplied with standard connectors. To get temperature value from output of a thermocouple, you need high precision amplifier and proper compensation circuit due to
