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
Matthew Leone from LeoneLabs has just completed his Laser Ball project, it was built inside a tennis ball and uses an Arduino Teensy to power and control 14 red lasers. The ball modes can be changed using a simple mini remote control. The project looks great and apparently took only 5 hours to complete, I am thinking that documenting the project must have taken just as long as the build
Koen sent in this great looking Robot Arm that he put together in one day. It looks and works great for something that was put together so quickly. Koen is still working on acquiring some tools help him with his robot building but until then all of his projects including this one is hand built. “It’s really really simple i build this using two servo’s and two strips of aluminium.
