The GI SP0256 chip is an early 1980s bit of technology. It’s a 5V (to 7V) NMOS chip which is compatible enough with the 5V TTL circuity common in that era. 5V TTL disappeared for a while, then came back with the Atmel _28-based Arduino boards, many of which run at 5V. The SP0256 chip

many cases switches are just switches. They directly control the flow of electricity to an appliance, flashlight or mains-voltage lamp. An example of this is the switch on the wall in your living room. In many cases nowadays however, switches are digital sensors, meaning that instead of directly controlling a high-powered device, they are controlling

This shield allows to connect an Arduino with DMX equipment. It implements the RS485 interface to adapt the electrical levels needed for DMX connection. This shield has been designed with flexibility in mind and allows the user to choose between several Arduino pins for digital input and output of DMX data, it supports a microSD

You are building a cheap soil moisture sensor so the brain can read the amount of moisture in the soil. The version we are building is very low tech, but it is also very cheap and easy to build. It consists of a block of packing foam with a couple of wires shoved into it.

I was going to make a huge write-up on this, but I can’t be bothered right now. I’ll probably do something about it later. Until then, have an Arduino sketch. If you don’t know what you’re doing with it then chances are you don’t have an Arduino, in which case the file is useless to

One of the goals of Movable Party is to provide an interactive experience for audiences/participants. Since power will be generated from a hub motor attached to the rear wheel of each bike (see this post), the speed of the rear wheel directly translates to the amount of power generated. Detecting how fast the rear wheel
Rear Wheel Tachometer using arduino Continue Reading
This is my first arduino robot, and I am quite happy with the outcome. What I came up with is a robot that with modifications can do just about anything in the realm of small arduino robots. The electronics are very simple. You only need an H bridge, and a simple setup for the sensor

Introduction I created the StorageBot to help solve a problem experienced by most Makers. After many years of accumulating thousands of parts stored in storage bins, I began to go crazy looking for parts scattered between so many of these bins. The hardest parts to find were always those rare miscellaneous parts that were thrown
StorageBot – voice controlled robotic parts finder using arduino Continue Reading
I developed the camera trigger unit in order to synchronize various events and actions during free-flight experiments with hawkmoths in the wind tunnel described in a previous post. More specifically, the goal was to trigger multiple high-speed cameras and have LEDs that indicate the exact timing of electrical stimuli delivered via a miniature stimulus chip

Stage combat is the art of theatrical violence. Rather than resembling fencing, stage combat is choreographed like dance for aesthetic and theatrical effect as well as for safety. Over years of choreographing and teaching others stage combat choreography, I realized that one of the most difficult aspects of teaching someone choreography is the necessity of
