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
Laser Soldering is an interesting concept, instead of heat from an iron or hot air heat a laser with a specific pattern is used to heat the lead, pad and solder to create a perfect solder connection. I can imagine the next generation of soldering system where the pick and place machine will both place the part on the PCB but it will also immediately fuse it in place permanently.
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.
Dave from Plastibots had some fun with the brake lights of his Nissan Juke. He added some red LED lighting strips to the car and made a custom circuit to drive them. He is getting power from the parking lights and taking in a signal from the brake lights. When only the parking lights are on the lighting strip is PWM controlled to a level of 75%, when the brake
