Manual intervention to a PCB is usually always visible. With modern „No-clean“ fluxes it´s not that obvious as in the past. But still it doesn´t make resulting look of a PCB better. However, probably more important is the fact, that soldering residues are a potential risk, especially in humid environment – as they may cause […]

In this tutorial we make an Arduino-compatible board that holds the microcontroller in a ZIF socket. Updated 18/03/2013 Today we are going to make a different type of Arduino-compatible board, one that has a ZIF (“zero insertion force”) socket. Our reason for making this is simple – now and again you may need to program […]

Since you lacked the USB interface in your own Arduino board, it becomes necessary to use a homemade/ready-made USB to Serial Converter Module as an efficient and economical solution. Inexpensive and easy-to-use USB to Serial Converter modules are now widely available, such as one shown here. With the help of this little module you can […]

This is something we have really been meaning to write up. A few weeks ago we ripped out an RGB LED from an old Canon Scanner that was laying around and going to waste. Since then we’ve been playing around with the RGB LED element and decided to put it to good use. We have […]

PORTLAND, Ore. — The world’s first microelectromechanical system (MEMS) spectrometer on-a-chip was shown today at at Photonics West (San Francisco, February 10-12) by Si-Ware Systems (SWS, Cairo, Egypt with offices in La Canada, Calif.) Instead of transporting materials across sometimes great distances to be analyzed with a normal bench-top spectrometer, Si-Ware’s MEMS-powered spectrometer fits in […]

Simple Remote Data Plotting using Android / Arduino / pfodApp This Instructable shows you how to plot Arduino sensor data on your Android mobile and capture it for later downloading to your computer.  These instructions are also avaliable at www.pfod.com.au No Android programming is required and very little the Arduino programming is needed. It is […]

A frequency generator is a very handy device in electronic design, development, testing and trouble shooting. It is such a kind of device which can generate the required frequencies which can be then applied directly to the target device for testing it. There are frequency generators which can generate the required waveform like sine wave, […]

A do-it-yourself Delta Robot kit that’s fun to build, sharp to look at, and a great point of departure for your own project! Want to make your own delta robot? Do you support the global onslaught of adorable little yellow machines? If you answered yes to either of these questions… then we have the best […]

Key Features: High power handling 30 dBm @ DC 36 dBm @ 8 GHz Maximum voltage (DC or AC peak): ±10V on the RF ports Total harmonic distortion (THD): –84 dBc Configurable 50Ω absorptive or open reflective switch via a single pin (LZ) Packaging – 20-lead 4 × 4 mm QFN Description: The PE42020 is a HaRP™ […]

This is a fun speaker timer I made for some upcoming conferences.  It uses a 4-digit charlieplexed LED (pseudo 7-segment) display and is driven by a AVR ATMega328 or an Arduino.  It allows a default time to be set, can be paused, and will put out 5 Volts on several IO lines when 10, 5, […]
