This article describes a simple continuity tester based on an ATtiny85. The tester features a buzzer that sounds to help you determinate the trace continuity. It is designed for checking circuit wiring, or tracing out the tracks on a PCB. According to it's author David Johnson-Davies it...

Pi/104 is a Pi Compute carrier board in PC/104 format with industrial durability. The Pi Compute Module is a powerful tool for custom electronics projects. But if your project requires industrial grade specifications, you’re currently out-of-luck. This is where Pi/104 comes in - with...

This project is the ideal solution for high output, high performance high fidelity stereo head phone amplifier. The project consists of Op-Amp LME498720 and LME49600 as output driver. The LME49600 is able to drive 32Ω headphones to a dissipation of greater than 500mW at 0.00003% THD+N...

Inspired by the biology of a bee, researchers at the Wyss Institute developed RoboBees, man-made microbots that could perform endless roles in agriculture or disaster relief. A RoboBee is about half the size of a paper clip, weighs less than one-tenth of a gram, and flies using...

Ossia has created the world's first wirelessly-powered alternative to disposable AA batteries. The "Forever Battery" puts a long distance wireless power receiver into an AA battery format. The technology can receive up to 4W from a nearby RF transmitter (Cota transmitter), and includes...

Read about epitaxial ultrafast diodes in thia app note from IXYS. (PDF) During the last 10 years, power supply topology has undergone a basic change. Power supplies of all kinds are now constructed so that heavy and bulky 50/60 Hz mains transformers are no longer necessary. These...

SYZYGY Brain-1 is an open source, modular ARM + FPGA development platform featuring the new SYZYGY standard for high-performance peripherals. This new development board bridges the gap between Pmods and FMCs allowing high performance peripherals to be used with ease. The author claims...

The Universal Op-Amp Development board is a general purpose blank circuit board that simplify prototyping circuits for a variety of Op-Amp circuits. The evaluation module board design allows many different circuits to be constructed easily and quickly. This board supports single SOT23-5...
