We’re all going to wear slightly dusty looking 1980s motorcycling gear, and we’re going to drive really cool cars. Except of course Mad Max is fantasy, and the reality is likely to be unspeakbly grim. The future [Virgil Dupras] ...

Arduino Laser Harp

A couple of weeks ago I presented my culmination project, framed laser harp, at New York City College of Technology. Work on it was so interesting for me, that I decided to share it here. I am an Arduino amateur and don't have any professional experience in electrical engineering or programming. Neither am I a musician. Probably that's why I had so much fun: when you are moving blindly, you can't see the gr ...

30 Minutes HIV Detection Using USB Stick

In partnership with DNA Electronics,  Imperial College London researchers had developed a revolutionary USB stick that can detect HIV in the bloodstream. In order to detect the virus, it’s enough to use a drop of blood. Then the USB stick generates an electrical signal that can be read by a computer, laptop or handheld device. We have taken the job done by equipment the size of a large photocopier, and shru ...

PSU Burner – a power supply tester

Intro What does one do when designing a power supply? Well, build a power supply tester, of course. One of the simplest things to build is a constant current load. This will allow for testing of the endurance of the power supply, as most of the designs out there are using slow components. However, I wanted to make a better one: one that I could hook up to my Analog Discovery and generate a test waveform to ...

Web-Based Pool Controller W/ Raspberry Pi, Arduino, Xbee and Digital Thermometer

This simple system allows web based remote control of a swimming pool pump and heater, or any device that be switched with simple relays. It uses a Raspberry Pi as the main controller and web server. It also uses a remote thermometer run by an Arduino at the pool, powered by a battery and a solar panel. Two small XBee radio units supply the data link between the pool thermometer and the main controller. I h ...

STEAMPUNK RADIO LOOKS THE BUSINESS

Radios are, by and large, not powered by steam. One could make the argument that much of our municipal electricity supply does come via steam turbines, but that might be drawing a long bow. Regardless, steampunk remains a popular and attractive aesthetic, and it’s the one that [Christine] selected for her radio build. The build cribs from [Christine’s] earlier work on a VFD alarm clock, using similar tubes ...
