Over at NerdKits, Humberto shows how to build a piezoelectric-based sound meter fed to an LED display, using their USB NerdKit. By using the piezoelectric buzzer that comes in the kit as a microphone, and adding a transistor and a few other components, you can create a sound meter and send its output to an […]
From the MAKE Flickr pool JoeLMutantE’s DIY step sequencer looks about as high-end as it gets. Dubbed the Project Stella, the rack-mountable monster was created as an antidote to standard linear interfaces – Stella is an analog step sequencer based on an old P3 sequencer kit. It has been made trying to make some different […]
From the MAKE Flickr pool Macetech built this dazzling RGB coffee table – IKEA Granas side table (over 2×2 feet, big enough for coffee table) with 9×9 array of 81 ShiftBrite RGB LED modules. Currently running a simple sine plasma into HSV/RGB conversion on an Arduino (Seeeduino). Wow – more than a conversation piece, I’m […]
For the next issue of MAKE, our second robot-themed issue, I’m doing a review of one of my favorite robot-related books, Valentino Braitenberg’s Vehicles: Experiments in Synthetic Psychology. It is a seminal work in robotics, especially with behavior-based robotics, BEAM, and other forms of simple, bottom-up robot architectures. Alex at Tinkerlog decided to build a […]
It’s the simplest semiconductor. It ushered in the age of radio. Say hello to the electronic valve that rectifies and regulates, the diode!
Here are some recent video clips from George Sanger and Jeri Ellsworth, aka The Fatman and Circuit Girl. In the first vid, Jeri attempts to build a Sprinthariscope, a tool for viewing radiation, using the radioactive Americium from a smoke detector. She also attempts to pronounce Sprinthariscope and Americium. All three attempts fail, but it […]
In this adafruit video, Limor demonstrates how to set up Xbee modules to wirelessly control both standard-type and latching relays. Using Xbees to control relays
