Brett Dickins has uploaded a new video on the Mechanical Kinetic Art channel. We have featured some their moving sculptured before, this video features a number of sculptures, the first is 9 wooden gears that rotate around themselves. There is a motor driving the sculpture which looks like it must be connected to the center gear. I am assuming that the 8 outer gears are connected with a square frame
If you have ever been in a remote area and pulled out your laptop I bet you couldn’t find any open WiFi hotspots. Well with this Wind Turbine powers WiFi-Repeater that Dan Lampie and David Brenner from the Rochester Institute of Technology built that problem has been solved on a tiny budget. A highly directional antenna is used to send and receive the WiFi data from a location with internet
Spiral Brain (who was a recent contest winner) has made an interesting Spinning Mirror Laser Project. At first when I watched the video the beginning looked like someone was spinning a few bright LEDs in their hands on a dark night. The patterns that followed show off the capability of the system to make some nice looking complex pattens. “The main hardware setup consists of a Laser and two motors.
The prize this week is one of our new IR Jammer kits that was just released this week, this will let you jam the infrared receiver on any infrared remote controlled item such as a TV or stereo. If you are looking to solder together your first project this would be a great project to start with since everything is through hole (no surface mount components). This contest will run
Andrei Mehiläinen from the Tampere University of Applied Sciences has completed a number of interesting projects. Two of the most interesting ones are the Temperature Logger and the LCD Thermometer. The temperature logger uses a PIC18F4550 microcontroller and a Microchip MCP9701 for sensing the temperature. I used the LM35 in PWM Fan Controller project but based on what I see I think I will need to look at the MCP9701
Our friend Daniel Eindhoven from Megavolts found a great price on some huge used capacitors. These capacitors normally cost around $90 each, Daniel was able to pick them up for around $2 a piece! That is one hell of a huge capacitor bank on a nice budget. He also designed an interesting mechanism to tie the batteries together. Instead of using wire or busbars he designed a few laser cut
Remember the Tool Carying Robot that we featured here many months ago? Well there is now a new remote controller for that robot, the controller is universal so it can be adapted to control other robots as well. The design is based on a Parallax microcontroller and Xbee chips for communication. Thanks for the tip John
