This is a cool 3D UV Laser Printer, you can see lots of other details over at the Rob Hopeless site. It uses a UV laser to print items in a container of liquid UV-curable photopolymer. There is a platform that moves the item being printed down as the laser beam traces to solidify each layer in the polymer. The printed items look a bit gooey but this is an
Frank Zhao, an electrical engineering student at the University of Waterloo just made this cool Toaster Oven Hacked into a Reflow Soldering Oven project. If you are working on a project that has SMD components in it you will need to select a way to reflow the solder paste, there are lots of DIY methods out there and one popular method includes modifying a toaster oven into a reflow oven.
Martin Landwehrmann from Germany sent in a ton of great build pictures of this BIG DIY LED Matrix and an English description on what André Zibell, Tobias Mc Fadden and Martin have been working on. By the pictures you can see that this creation wasn’t a simple task to put together but the results are great! Link More Video Links: Video 1 Video 2 Video 3 Video 4 Video 5
Thanks to Pabloxid for sending in his dancing robot (translated into English). His movements reminds me a bit of Keepon. “Its output devices are: the 2 DC motors at the base, the 3 servos that move the “head”, clusters of LEDs in the “eyes” and an audio system that plays both the internally generated beeps like sounds stored in a small flash drive, using a car MP3 player. His only
If you have a LEGO Mindstorms NXT system you now have a new way for it to communicate. Using the Dexter Industries Wifi Sensor you can now connect the system to your WiFi network for a new range of project ideas. Dexter Industries has spent the entire week cooking up interesting ideas and documenting them on their site for all to enjoy. “The sensor can be used to communicate via
The Open 7400 Competition is over and the winner is…. Capacitive Sensing, the Hard Way! This is a project that is somewhat simple when done with a microcontroller but takes quite a bit of effort to pull off with 7400 chips. I think the winners are still trying to determine who wants what since I haven’t heard who is going to be awarded the three IR Jammer kits yet. “The
This thing looks like a ton of fun to fly. I am not sure if a simple helmet would be sufficient for me to take the e-volo for a spin though. It’s one thing to fly a small toy multicopter around using a remote but when it comes to strapping yourself into the center of one that weights in at 90 kg! I hope that the e-volo is what it
