dmainmon @ instructables.com has build an analog signal graphing project using Arduino Mega 2560 and a 2.8 TFT display. This project is used to display two analog signals as line and bar graphs. Touching the screen pauses the graph and opens a menu to adjust setting for the...

Chris Palmer has built this coolometer project to measure the cooling effectiveness of various fan: I was wondering about how I was going to calibrate the airflow reading but then realised that the flow rate is not actually what I am interested in. It is the cooling effect the...

Marko Pavlin has designed a Mini USB dongle with STM32F0xx that is connected to USB and controlled via command line interface. Mini USB dongle with STM32F0xx is suitable many for simple, mini projects. I attached speaker to Timer14 PWM output (Pin PA6) and LED (or optocoupler...

Milen @ instructables.com has designed a Function Generator based on the popular MAX038 and is controlled by ATMega328PU. Signal characteristics are displayed on a LCD screen. The digital features of the function generator were performed by one Atmega328 chip. Its functions are the...

Luca Dentella has build a Nixie thermometer to measure the temperature of the liquid cooling system, file are available on Github. I decided to log the design and the development of the project in ten blog posts. They show my “divide et impera” approach: I divided the whole...

circuitspecialists.com has published a new guide on how to build your own 8x8 LED Matrix on a prototyping board. In a later guide they will show how to program it using an Arduino Compatible board. Today we will be starting our adventure into the deeply complex, yet totally...
