Jon Wise demonstrates his Raspberry Pi 3D Printer, he is using a pen in the demo but it can use an extrude to print items. The mechanical movements leek very complex when compared to a standard XY table that is controlled using 2 stepper motors. The Pi has enough number crunching ability to get the job done though. I can’t wait to see this printing a complex shape, the
While watching the video I was wondering why there was so much complex electronics for the AZIZ – LED Microscope Illuminator Project. I was thinking that a simple dial to vary the intensity would be all you would need. If you are thinking the same thing have a look at the video starting around the 4 minute mark. By having modes that allow you to spin lighting patterns and
These Rave Shade – LED Glasses look like a ton of fun. They are Arduino based and use 74HC595 shift registers to light all the LEDs. At first I though it was a silly design since with a PCB sitting on your face you would not be able to see anything. But later I saw the small circles that are cut into the board which allows you to presumable see
Want to annoy IronJungle? Tweet a bunch of commands to his Twitter Robot Hand! His hand is monitoring the Twitter stream using a Raspberry PI and will act on your commands (seen below).  “A Raspberry PI monitors the tweets to @OurCatDoor. The PI’s GPIO acts as inputs to a PICAXE 18M2 which controls five servos on a robot hand. You can control the “The Hand of PI” by sending
 It sucks when you have a perfectly good piece of hardware that mechanically functions but the controller dies. This is exactly what happened to Davide Gironi from Milan Italia when his dehumidifier stop working. Instead of placing it next to the curb for garbage pickup he investigated what the issue was. Turns out the humidity switch was no longer working. He installed an AVR Atmega8 microcontroller system that
  If you have some items that you would like to make some vacuum formed molds of and have access to a 3D printer this Vacuum Former project might be for you. All you need to do is place your item in the form. The plastic form material is heated then dropped over the item to be molded and a high power vacuum cleaner is used to suck the
Ben Rothschild wrote in about an interesting project that he is working on. Watch the video above for more details, if you would like your own Chipper – ATtiny Programming and Prototyping Shield please support his Kickstarter. “As a high school senior and electronic enthusiast, I recently built a programming shield for 10 different types of ATtiny chips that can be used with either an AVR programmer or Arduino
