Recently Gesture controlled Laptops or computers are getting very famous. This technique is called Leap motion which enables us to control certain functions on our computer/Laptop by simply waving our hand in front of it. It is very cool and fun to do it, but these laptops are really priced very high. So in this […]

Hi all! After a couple of months with a lot of work, I come here again with the last board I develop before Christmas. It’s a dual USB serial and I2C converter based on two MCP2221 Microchip 2.0 USB-Serial bridges. I develop it as a need on my work with the last project I’m involved. I

We initially made HealthyPi as HAT add-on board for Raspberry Pi. Now you can run the application on any desktop PC with a USB port. Project We introduced the HealthyPi as a HAT add-on for the Raspberry Pi, turning it into a full-featured, medical-grade open patient monitor. However, we realized later that people also wanted

I had to delve deep into the code, but I finally got nodebots working on an Arduino Zero Story I recently received an Arduino Zero, arduino.cc’s latest offering. I’d been experimenting with nodebots, so I decided my first Arduino Zero project would be a nodebot. Anna Gerber has an excellent tutorial for doing nodebots using

Purpose and concept The “LayoutLights” concept was born when I wanted to remotely control (using a PC with a USB port) the lights on the train layout. I wanted to be able to switch on and off all the lights in buildings, structures and on platforms, streets and other locations.The basic principle is simple :

Among my recent electronics purchase spree was the amazing Teensy LC from PJRC. It has a nice ARM Cortex-M0+ processor, real hardware USB, and what’s the nicest part, an Arduino add-on called Teensyduino which enables easy programming with Arduino, but with support for many of the hardware features. Now I started playing piano a while

I stood in stunned silence at the smoke billowing up from the hardware on the workbench. Just moments before, it had been operating as expected, before self-destructing with a sound that can only be compared with a gunshot. The failure of the hardware under test had an unexpected consequence: the computer that had been using

Digilent recently released a new FPGA development board. The Arty board. The Arty is designed to be used exclusively with Xilinx Vivado, and designed specifically for use with microblaze. This tutorial covers how to use the out of he box design that ships loaded into Arty’s Quad-SPI Flash, with I/O and UART. To view the
