Peter Marchant is going to have a wonderful Christmas with this MIDI Christmas Tree. As you play notes on the MIDI keyboard the tree lights in a cool pattern. “Using an Arduino and a SparkFun MIDI Shield to control Christmas Lights with a MIDI keyboard. The lights cycle colour (green, red, blue, orange) for each note or chord. Improvisation based on the minor blues scale on D.”
This Reverse Geocache called the Captain Herrmano’s Mystery Box packs a ton of sensors into the box and some slick programming brings it to like with a full on treasure hunt. “The housing – that is, the box itself – came from a Nanu Nana store (which is a German chain of stores). Inside of the housing, an Arduino Mega controls and receives information from different sensors and boards
What a great job the team at Johns Hopkins University Applied Physics Laboratory did. They built this Double Prosthetic Arm with Mind Control to allow Les Baugh to once again have arms and hands. He lost them in an electrical accident over 0 years ago. I can’t imagine the feeling Les has after so many years living without arms and now finally have some high tech versions to work
JEELABS did a nice WS2812B LED Driver Project that uses an ARM LPC810 running at 30 MHz to get things done. “Sending 12 bits @ 2.4 MHz takes 5 microseconds. If we were to set the LPC810 to run at its maximum 30 MHz clock, we could probably drive the SPI hardware entirely via interrupts, but for a simple timed example this is not really necessary. Instead, we can
 These Internet Controlled Robots are not available to play with all the time but if you keep an eye on the Twitter channel you will have a chance to have a look and give them a try when they are online next. “I only put together one robot kit previously, then these two robots both started as Activity Bots. I hooked up a Raspberry Pi with an HD
 DickB1 built a very interesting clock called Numechron Digital Clock which is based around a very old clock. It uses an AC motor to keep time which keeps time based on the 60 Hz in the AC line. “I really liked the Art Deco style of the Model 1364 case and chose to emulate it, although my clock is considerably larger than the prototype. While mimicking the original
 DonEduardo built a Talking Autonomous Robot that has some personality. It wonders around looking around with his ultrasonic sensors, it can look to see if it is enclosed where it can take a nap. Every now and then he speaks. Very cute robot! The brains of the robot is Parallax based, the locomotion comes from a Roomba.
