Overview: This instructable will construct a series of custom sensor modules and an Arduino shield. Such modules are available from many different sources, but fans of the Instructables website would probably find satisfaction in making their own. Each module will be a set size of 1.5cm by 2.5cm and employ a three pin connector of […]

A four-channel PMBus digital power-system manager IC, the LTC2975 from Linear Technology, performs current, power, and energy monitoring of the intermediate-bus input to point-of-load (POL) converters. The device relieves the host of burdensome computation and poling by providing the energy consumed, reported in joules, and the elapsed time through a PMBus interface. When combined with […]

Okay so the Title is indeed a bit of a mouthful lol ! Ive been needing to mess around with a desire for MORE Input/Output pins than the Arduino UNO and nowadays the UNO uses an Atmega328 microcontroller, & its limited to only about 20 Input/Output pins 🙁 Well if you’ve been messing around with […]

The ADP2384 is a synchronous step-down, dc-to-dc regulator with an integrated 44 mΩ, high-side power MOSFET and an 11.6 mΩ, synchronous rectifier MOSFET to provide a high efficiency solution in a compact 4 mm × 4 mm LFCSP package. This device uses a peak current mode, constant frequency pulse-width-modulation (PWM) control scheme for excellent stability […]

My kids wanted to have a head controlled mouse for playing Minecraft – they wanted to move their heads and have the field of view move. I decided that was a challenge I couldn’t resist, so I decided to build a movement controlled mouse using an arduino and a gyroscope chip. Components A-Star 32U4 Micro […]

The Arduino Ethernet Shield is a sweet toy!!!  Everybody, from the beginner who got their Arduino yesterday and hasn’t slept since, to the hard core pro who learned c as a second language, can learn how to use the Ethernet Shield and have lots of fun with it.  Its that awesome! As soon as I […]

Introduction Electrodes on the skin can be used to measure muscle (electromyography, EMG) brain (electroencephalography, EEG) and heart (electrocardiogram, ECG/EKG) activity. These electrophysiological measures are popular for clinical, research and hobbyist applications (such as brain computer interfaces). Most commercial systems are “medical grade” – these expensive systems offer high precision (16-24 bits), participant electrical isolation […]

Welcome ladies and gents! As an entrepreneur, I’m always looking for great projects to share.  Myself and two other classmates recently put together a project for our Master’s of Engineering program in Technical Entrepreneurship, and we’re thrilled to share our vision with you.  Remember that old Connect 4 game sitting in your basement/closet/chest/Batcave?  You’ve always […]

Silicon Labs have introduced a tiny 3 mm square hybrid TV tuner chip which supports reception of all worldwide terrestrial and cable TV transmission standards. According to its preliminary data sheet its design eliminates the need for an external balun, LNAs, SAW filters, and inductive power supply filtering. Some competing TV tuner solutions also eliminate the […]

This is a project I worked on for my electronics class at Pomona College. Thanks to Professor Dwight Whitaker and Tony Grigsby for their help and guidance throughout this project, and credit to Jonathan Wong for the idea for this project! Also, here’s a list of Instructables I looked at for ideas/inspiration while working on […]
