It is an interesting question, isn’t it? People not “inside” the maker world or not expert in programming think that Arduino and RaspberryPi are two flavours of the same object. Like if you ask “Mac or PC” rather than “Ubuntu or Debian” if you’re nerdish. Indeed, Arduino is a microcontroller, while RaspberryPi is a microcomputer…
OSOP, which found Kickstarter success with its Raspberry Shake seismograph add-on board for the Raspberry Pi, has now returned with a Raspberry Boom add-on board and infrasound sensor that detects inaudible sound. The same Kickstarter campaign is also selling a new Raspberry Shake and Boom product that combines the Boom with the seismograph capabilities of the Shake….
This is a fairly simple add-on for mobile phones to enable SMS-like messaging in a group when outside cell coverage, or in disaster scenarios. It utilises Semtech LoRa radios, for low-power/long-range communications. More info Build it yourself Boards, sensors and kits for projects like this one. Browse the shop
If you like electronic music, you must know Daft Punk’s glowing electronic helmets. Now, thanks to this Electronoobs tutorial, you can make a very good and affordable replica for around $20 and 30 hours of print time. This is a very simple project that uses the Adafruid library to control a RGB adressable LED strip that…
