Its back, with new features in v2.0: Facebook integration – Facebook registration Page to track and graph drink consumption Touchscreen with gesture support RFID user login – sync with Facebook profile photo SQL drink database […]

PORTLAND, Ore. — A new world record has been set in wireless data transmission rates — 40 gigabits per second, which is over 40-times faster than the ceiling for Long Term Evolution (LTE) Advanced of 1 Gbit/s. The breakthrough was announced at the Compound Semiconductor Integrated Circuits Symposium conference in San Diego on Oct. 22, […]

This instructable (entered in the Arduino Challenge contest – you can vote for it above) shows how to make a stripboard Arduino shield for programming either ATtiny45 or ATtiny85 microcontrollers with an Arduino, as per these tutorials from the High-Low Tech group at MIT: Arduino board as ATtiny programmer Programming an ATtiny w/ Arduino 1.0 […]

In this lab you will be using a program to enter a schematic and lay out a printed circuit board (PCB) that will then be manufactured.  At this point of the semester you don’t know enough to design your own circuit, so I am giving you one that we will use again later in the […]

This Instructable will demonstrate how to make a remotely activated sound file player. It uses an Electric Imp, an Adafruit Wave shield and an Arduino Uno The Electric Imp enables you to quickly connect devices (including arduinos) to the internet through your Wifi network. The Adafruit Wave shield makes it simple to play audio files […]

Description After finishing my last project – “Simple LC meter“, there were some discussions in the forum I am a member of, that ability to measure electrolytic capacitors would be very useful in this type of device. I searched the Web and found a very cute project named LCM3 on this Hungarian site: hobbielektronika.hu . […]

Microkite is a DTX module built to utilise the great potential of the new PIC32MX1xx/2xx microcontrollers. It integrates a power supply able to provide power to the external user circuit as well, a microSD connector for data storage and a USB-UART bridge for easy communication with a PC terminal. The module is intended for inclusion […]

Bingo! My granddaughter enjoys playing Bingo, so I went out and bought her a cheap set at a local discount store. The cards and the markers are fine, but the spinner disk for selecting the numbers is a piece of garbage. It flew apart about ten minutes into the first game. True, I could have […]

The goal of the project is to come up with an affordable yet generic vibrotactile feedback device to be used for educational purposes. A chemistry learning environment is developed to demonstrate a specific application of our device, in which users can manipulate ions and feel the corresponding electromagnetic attraction and repulsion forces through the vibration […]
