This is an interesting SX48 micro-controller midi music maker. You can download the schematics and code on the website. Here is what the maker has to say about the project: This project uses an SX48 microcontroller at 75 MHz as an 8-channel frequency-synthesis music player with three instruments (selectable per channel): square wave, triangle wave, […]
This project uses a Boarduino (breadboardable arduino) + Parallax ping (ultrasonic sensor) to achieve the near-ninja sword-catching grabbiness seen above. Hearing that *crank* noise sure brings me back – those toy claws were always much simple fun! – boarduino robot claw[via] Related: The chimney claw Boarduino – Breadboard-compatible Arduino clone
Ladyada posted a thorough tutorial regarding Arduino to LCD wiring – For a soon-to-be-released project I needed to have a character LCD display. I’ve got a box with a few of those $10 parallel LCDs that are so popular. There’s even a few libraries at the Arduino playground for easy use. Dave Fowler from uCHobby […]
Some of my Dorkbot DC cohort put on this wonderful robot célèbre each year. This year, Make: DC, another org I’m involved in, will be doing workshops too (using Solarbotics parts and kits). Robot Fest 2008 will be April 26 at the Historical Electronics Museum, Linthicum, Maryland. Hope to see you there. Robot Fest
Reminder MAKE will be @ Robo Business for the next two days, we’ll have some “live” coverage and fun from the event up as we hit the floor. Pittsburgh area makers hit me up on email if you’re going to be there, oh – here’s a bit about the conference. Now in its fifth year, […]
Everyone who works with large data sets in Google Maps has come across the problem of displaying a bunch of markers in a small area. Not just an eyesore, displaying anything more than a hundred marker icons at a time can bog the browser down on a lot of platforms, Safari on PPC Macs delivering […]
This AVR-controlled autonomous robot is programmed to follow the brightest light in the room. It uses two wheels and a ping pong ball as a third wheel. Really simple components here and it runs on three AA batteries to sweeten the deal. Building an autonomous light finder robot
