If you have a spare SCARA Arm kicking around and need a new project this 3D Printer built using a SCARA Arm might spark some inspiration. Via: Make “This project documents the re-purposing of a ‘rescued’ 1980’s IBM 7575 SCARA Robot Arm, into a functional 3D ABS printer. The project features some motor upgrades,  documentation of encoder positioned motor control feedback theory, the interminglings of EMC2, heated workspace construction and
Inventor Izhar Gafni made a Cardboard Bike which is slated for mass production. The cost to produce one of these bikes is around $9 since the materials being used are inexpensive, the selling price is expected to start at $60. I was surprised to read that the weight that the bike can handle is 485 pounds, I am thinking that this is greater than the typical off the shelf
 North Street Labs built a cool looking light show project for the Hippodrome. It is made using a large number of smart RGB LED strips. The effect sure adds a huge amount of ambiance to the party! I can see this system becoming a system that bars and clubs would want to order as a permanent installation. Read the article for lots of tips on purchasing electronic parts
Got an Arduino and looking for a cool project? Have a look at this RGB Arduino LED Clock over at ElectronicProjects.blogspot.ie. It has some cool specs and looks great! “180 RGB LEDs driven by TLC5925 constant current LED drivers each LED addressed separately (12x TLC5925 with 16 outputs each). each colour adressed individually 4x 7 segment LED display Atmega328P as MCU DS1307 real time clock Photoresistor (for adjusting brightness)
Michael Chen from Panama wrote in about his troubleshooting and repair of his Corsair SP2200 Crackling Speakers. He has also entered this into the Instructable’s fix and improve contest so if you like it please vote for him. “Here is how I fixed a crackling SP2200 speaker However, the most interesting thing is how I troubleshooted the problem, which does not appear there since it is aimed to a
The Neurophone was invented by Patrick Flanagan and used radio transmitter that injected sound into the human nervous system. Antennas coupled a one-watt 40kHz transmitter to the body to inject the signals. Seems that Patrick was quite the brain since he developed and sold a guided missile detector to the U.S. military when he was 11 years old. Andreas Hahn has make a modern version of the Neurophone using
Chris from Pyroelectro shows us how to interface to an FPGA to allow precise control over a DC motor. “The goal of this project is to build a simple one input, one output system that will control a motor. The control input will come from a trimpot and the FPGA or CPLD’s job will be to use the input to create the proper duty cycle PWM output to the
