When at home, I do not carry my phone with me everywhere… so sometimes phone rings or an SMS comes in and I do not hear that. With the volume of music played by the teenagers at home, that is not a surprise 🙂 so I decided to build a small accessory that will show […]

This article describes a simple spectrum analyser for the 2.4 to 2.5 GHz Wi-Fi band. It’s based on the Cypress CYWM6935 Wireless Radio Module. Although the manufacturer doesn’t recommend it for new commercial projects, it is still widely available from eBay suppliers and Farnell here in the UK. The module has 1 MHz channel spacing […]

La estructura de la SD Es este post voy a intentar explicar un poco el código de nuestra ‘Gramola’ con corazón de Arduino. El principal problema que encontré para realizar este proyecto, fue la limitación de la librería SD, con su FAT  reducida que sólo permitía la los nombres en formato 8.3. La solución fue […]

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 […]

This project uses an Arduino, a pair of speakers, and a laser pointer to create a laser projector able to trace out designs in a dark room. To power it, I’ve cannibalized a PC ATX power supply capable of delivering plenty of current for the speakers. Most of this project was directly adapted from the […]

My next door neighbors have recently been playing their music really loud so that I can hear it through the walls. I’ve gotten tired of having to bang on the walls each time to get them to quiet down, so I decided to automate some payback. The premise is that my device will listen for […]

Background I read about the ESP8266 first in March this year and I didn’t know what to do with. And now I’m really fascinated how easy the connection of an Arduino to the Internet can be. Like others I set up a weather station on a breadboard first and sent data to thingspeak.com. This ends […]

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 reality […]

A hideaway cat litter box is a great way to make your apartment look like a residence for adults instead of crazy cat ladies. A hidden litter box in a cabinet, under a sink, or built in to some other furniture does a lot for appearances, but what about the smell? Here’s how you can […]

I’ve built a number of projects that have interfaced the output of the Simple Bat Detector with a microprocessor. The most recent was the BatLogger II. But I hadn’t come up with an easy way for others to experiment with this idea … until now. My friend, Frank, in Germany, had wanted to make a […]
