After the untimely death of my Mac Mini (the last thing Apple I never buy), I recycled her limping in a clock display LEDs. Technically, there is not rocket science: an Arduino reads the time from an external clock and displays a matrix of 8×6 colored LEDs for hours, minutes, seconds and a linear array […]

This instructable goes through how to design and print a variety of 3D models using a system called the ‘UCube’. Note:  I would love to eventually publish detailed instructions on how to make your own UCube, but since the design is still changing and improving, this post will gloss over a lot of those details […]

Activities of daily living (ADL) are self-care activities that are usually taken for granted, since as the name implies they are performed on a daily basis. If you have ever ended up in a cast, or on crutches you can empathize how menial daily activities can suddenly be very difficult to perform. Waking up in the morning and maintaining a schedule […]

*Check back for more updates on this build 🙂 So, have you heard of the Omnibot? Well! Any kid from the 80’s will remember how amazing this robot was. For you young kids, this robot was released in the early 80’s by Tomy. The robot was “programmable”, in the sense that the actions were recorded […]

How to: Speaking Clock Hello 🙂 Setup and Procedure The wave shield is interfaced with the Arduino Mega 2560 as normal. A couple of pins were remapped because the wave shield was initially made for a different device. The DAC pins were remapped to pins 22,23,24 and 25 on the Arduino board. The WaveHC library also […]

I’m still working on the LED calculator (original idea and most recent work) — I’ve finally got ’round to adding a rotary encoder to set the target system voltage. Now you can turn the potentiometer to set the LED brightness, turn the rotary encoder to set what voltage will be used in the ultimate LED circuit, and […]

I’m researching squeeze sensing as a mode of tactile interface. Here I will cover the process of developing a squeezeable sensor and the firmware/software concerns associated with interpreting the data from the sensor. This fulfills the “sensor project” for my class called Computational Principles in Media Arts taught in AME at ASU by Todd Ingalls […]

S.A.M. Spring Aided Machining (CNC with solvent) is a school project designed by three architecture students at CCA, San Francisco: Matt Boeddiker, Abelino Robles, and Tim Henshaw-Plath. (www.cca.edu) The machine is capable of rapidly prototyping and creating subtractive formwork that can be used to cast material. The machine was designed with the instruction of Jason […]

(This tutorial has gotten really popular recently, and I’m very pleased that so many people are interested. I learned all of this stuff while working on my first PCB. If you’re interested, I’ve started to sell the most recent version of my Arduino ProtoShield. If you’re making a shield, have fun and good luck!. If […]

Here we will be learning how to make a color sensor. my model consists of three cardboard compartments containing an LED – one red, one blue, and one green – and an OP550B phototransistor. The LED’s shine simultaneously on a solid colored card. The phototransistors are connected to an Arduino Uno, which converts the relative […]
