Open Sound Control on mbed microcontroller

Posted November 26, 2014 by Chris

"For independent study in MAT this quarter I sought to implement the Open Sound Control protocol on the mbed. This involved getting UDP send and receive working on mbed and then setting up a parsing / callback system that can take an incoming message and delegate it to the proper subsystem. "

USB6 ABV Platform

Posted November 25, 2014 by Chris

"Like the Arduino, the USB6 allows you to control robots, make electronic instruments, talk to sensors and interface with the internet. The main difference is that you *buy* an Arduino. You make a USB6. This is good for people who are more interested in the hardware side of things. For example, would you like to learn what capacitors look like? Would you like to try out some board etching techniques, especially alternatives to Ferric Chloride, like Hydrogen Peroxide, etc?"

Robotic Arm with Kinect Interface

Posted November 24, 2014 by Chris

"To put it simply, it’s a robot arm that copies you. Think motion capture, but the results you see in real time on hardware…I did not build this thing in mind with any one specific application. What I wanted was an intuitive interface for controlling a robot. This robot could then be sent out into situations that humans can’t or shouldn’t go. "

Breadboarded 9 Volt Battery Charger

Posted November 23, 2014 by Chris

"9 Volt batteries extensively used in various electronics measurement equipment. Powering these devices with rechargeable batteries can be a cost effective solution. In this post a simple Lithium-ion 9 Volt Battery Charger design with overcharging protection will be presented. Charger is based on PIC16F876A microcontroller and uses its A/D module to monitor current flow into the battery."

Infrared IR Sensor Interface with PIC18F4550

Posted November 22, 2014 by Chris

"In this project, as promised before – we are going to demonstrate a PIC18F4550 microcontroller interface to IR sensor circuit….however you can do some more intelligent operations by adding some more logics to the microcontroller coding. Interfacing infrared Proximity sensors with Microcontroller is quiet easy."

Z80 Single Board Computer

Posted November 21, 2014 by Chris

"OK, it’s made on more one board, but you get the point. Based on Grant’s 7-chip Z80 computer, it uses his modified version of the NASCOM computer version of Microsoft BASIC running from an 8K ROM. The remainder of the Z80’s 64K address space is taken up with 56K of RAM."

The Open Steno Project

Posted November 20, 2014 by Chris

"Steno technology has existed for about a century, and has been compatible with computers for over 30 years, but until now the hardware and software necessary to write at 240 WPM has been restricted to professional stenographers. The Open Steno Project seeks to bring free software, low-cost hardware, and interactive learning tools to everyone who wants to use steno for their personal or professional pursuits."

Wireless BusCounter

Posted November 19, 2014 by Chris

"I’ve been working on creating a cheap, time-lapse camera that people could use to ‘sense’ the world around them. The cost of such a device would be around $10, when all is said and done, and having multiple of these devices would open up options for public computing that people have not considered – a world where people are willing to deploy “personal, public” electronics throughout their environment with the same ubiquity, recyclability and reusability as paper."

Prime-ary – Prime Number Generator

Posted November 18, 2014 by Chris

"For the last several weeks I’ve been hacking together a small prototype of a microcontroller (ATTiny2313)-powered prime number generator. I can finally say that it is complete, functional, and elegant. The name says what it does, so I won’t waste time describing it."

Infrared LED matrix

Posted November 17, 2014 by Chris

"We stripped out the insides of the device and mounted in our stackable led controller boards. These two boards are designed to convert random amount of LEDs to Arduino controlled matrix. There is high side controller – 8 P-channel mosfets per board. And low side controller uses TI TLC5940 16 channel led controller."
