This is an instruct able for making your own PWM (Pulse Width Modulated) fly back driver! The design is relatively simple and easy to make if you have basic electronic skills. In fact, you don’t even have to know how a transistor or a MOSFET works to make this. You only have to follow the …
Recently, I purchased a power supply that claimed a max current of 2A and 0~15V. So I wanted to test it. I had a 36 watts bulb (used in motor cycles), but that was too much. Then, I thought of the dummy load that is explained by Dave in his video blog. My version is …
I am in the process of designing a function generator and I needed a frequency counter to check it against. This project uses a minimal number of components for a very economical and compact design. A bare-bones Arduino clone is at the heart of this project and the measured frequency is shown on an LCD …
I was in need of a function generator to produce audio signals for testing effects / amplifiers; as well as TTL clock signals for digital circuits. As function generators generally cost about £200 new, I decided that I would instead build one myself. This project uses the XR-2206 integrated circuit to generate the waveform. It …
Graphene can increase the sensitivity of micro-electro-mechanical system (MEMS) Sensors by up to 100 times, according to researchers at the Swedish KTH (Kungliga Tekniska Högskolan) Royal Institute of Technology in Stockholm. “The advantage of using graphene membranes for piezoresistve Sensors is their extreme thinness,” Frank Niklaus, a professor at KTH, told EE Times. “The sensitivity …
Wi-Fi is something we have wanted to do for a long time, but there are a lot of technical and regulatory challenges around it. If you’re running an OS on an embedded PC like the Raspberry PI, Wi-Fi is simple, you buy a cheap dongle and the intelligence is in the driver. For a low …

Introduction From project to project the number of hex files on our PC was increasing. Many people send us their virgin ATMegas to get them flashed. And last not least distributing PCB’s and pre-flahed chips via agile-hardware forced us to burn many, many AVRs. In principle this is a work an ape should do but …
A while back I picked up a Spark Fun 128×64 LCD and an Ada fruit 66-channel GPS module to have a go at making a GPS clock. The great thing about setting the time and date via GPS is that I won’t have to put any buttons on the clock. It’ll set itself, and appear …
TMPM470FDFG and TMPM475FDFG enable dual control of two brushless DC motors Toshiba Electronics Europe has announced two new products to join their range of ARM® Cortex®-M4F based TX04 series microcontrollers. Both the TMPM470FDFG and TMPM475FDFG are capable of operating two brushless DC motors simultaneously. The new microcontrollers aim to satisfy ever-increasing demand for more energy …

GPS Clock Assembly, Part III January 10, 2015 Filed in: GPS | Arduino | Electronics | Clocks | Laser Cutting Pinoco was hit with the holiday rush, so it took a few extra weeks to get my new batch of laser cut acrylic. I nailed it this time. Right away I could tell the engraving …
