PULPino is an open-source microcontroller system, based on a small 32-bit RISC-V core developed at ETH Zurich. The core has an IPC close to 1, full support for the base integer instruction set (RV32I), compressed instructions (RV32C) and partial support for the multiplication...

conoroneill.net has coded an Espruino Pico to work like a HID device. Now that the Espruino Pico has (beta) HID support, it can pretend to be a keyboard or mouse (or other HID compatible device). This makes it possible to send characters to the active window on your...

davedarko created this Adafruit Trinket Pro shield for the HP QDSP-6064 bubble display. The design files and source code are hosted on GitHub. An additional temperature sensor in the form of the LM75 can be added to this bubble display shield. The atmega32p is capable of driving up...

Jhon_Control @ instructables.com has written a tutorial on how to monitor temperature using the ESP8266 and DS18B20 and display the data on Emoncms platform.  Emoncms is an open source web application that enable you to monitor and visualize different environmental data. ESP8266 +...

A group of researchers from the Cardiff University has demonstrated the first practical laser that has been grown directly on a silicon substrate. by Graham Prophet: The lasing structure was formed in indium arsenide/gallium arsenide layers grown directly on a silicon substrate; the...

Two low-power 6-axis inertial modules introduced from STMicroelectronics, the LSM6DSL and LSM6DSM. Both they pack a 3-D digital accelerometer and a 3-D digital gyroscope in a miniature package. These modules consume 0.4 mA in combo normal mode and 0.65 mA in combo high-performance...

educ8s.tv has published a new Arduino Video tutorial: High Power LEDs are very popular and low cost nowadays so I thought it would be a good idea to learn how control them with Arduino. So, I built a simple project that simply turns on a 4W Cob LED when the button is pressed. When...

Max Maxfield @ edn.com writes about the famous Gerber format and the history behind it. Gerber format is actually an ASCII vector format that defines copper layers, solder mask, legends on a PCB and it's used by manufacturing companies to produce the actual PCB. The incredible...
