“Simulated Glowy Physics! These LEDs interact with motion and looks like they’re affect by gravity. An Adafruit LED matrix displays the LEDs as little grains of sand which are driven by sampling an accelerometer with an Adafruit Feather. The …
“Following on from looking at commercial products for sleep monitoring using EEG, I thought I’d take a look at more DIY based approaches using some open source sensor boards and a basic microcontroller. This is quite a classic module …
“This project describes the development of a multi-mode scanner platform, which can be described as a Scientific Tricorder. A few years ago, after taking my first contacts with embedded electronics, I decided it would be time to try building a …
“Small battery-operated board with low-power image sensor that captures images at regular intervals and saves them on a memory card. I recently posted some of the work I was doing on twitter and I got an e-mail from someone I …
“After playing around with Freetouch to make a knitted fabric switch, it was found that the sensor reading varied depending on the type of interactions. For example, prodding the fabric resulted in a much lower sensor reading than grabbing the …
““How is the weather?” In modern times, for a reliable answer to that question, you’re much better off asking a machine than a human. Wouldn’t it be fun to build such a device yourself? With that in mind …
“Use a couple of packet radio boards to mirror one robot’s movements in the other one from up to 500m away. Swarm Robots The idea of having a large number of robots doing tasks in unison is nothing new …
“Use a pair of packet radios to draw and then send pictures between the two devices without WiFi or Bluetooth. The Idea Reliance on certain wireless networks/protocols can add significant costs to a project, as well as limit how …
“This little device pulls your local UV index from EPA and display the UV level in 5 different colors and also displays details on the OLED. UV 1-2 is Green, 3-5 is Yellow, 6-7 is Orange, 8-10 is Red, 11 …
“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. There are a lot of hardware …
