ucexperiment.wordpress.com has published a series of tutorials on how to use assembly language on Arduino. This can be pretty helpful if you want to do some advantaged coding on Arduino. An inline assembly statement is a string which specifies assembler code. The string can contain...

Thomas Gonnot has published a RGB LED Strip Controller based  on STM32F0 microcontroller. The controller is able to power NeoPixel and DotStar protocol RGB LEDs. A simple controller for a RGB LED strip, with independent control of color and intensity. The design is based on a...

Dilshan Jayakody build a auto monitor brightness controller that adjusts your monitor brightness according to lighting conditions. He writes: The sensor unit of this system is build around PIC18F2550 8-bit microcontroller. To measure the light level we use LDR with MCU's inbuilt ADC....

Peter van der Walt @ OpenHardware.co.za has published his newest machine design – an open source pick and place machine. Open Source Pick and Place Machine -...

Near Field RF probes can be very helpful when tracking down sources of unwanted RF emissions or radiation. This video presents the basics of the E-Field and H-Field probes, how they work, and how to use them. Basics of Near Field RF Probes -...

Engineers at the University of California are focusing on measuring Sodium, Potassium, Glucose, Lactate in an attempt to measure an individual’s health. The team have developed a prototype that comprises a flexible printed circuit board holding five sensors. A new device is able...

Craig document his process of building a Better RTL-SDR TCXO with +-1ppm stability over 0C-55C range. Its hard to beat the cost and versatility of the ubiquitous RTL-SDR dongles, but the temperature stability of their reference oscillators isn’t sufficient for some applications....

Ken Boak discuss how to build a graphic user interface using cheap TFT toughscreen displays. This article is about using their lowcost graphics co-processor IC to provide a neat user interface for any low-end microcontroller. These days, when you can buy a 7" tablet for $50, there...
