 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
Wow, making Ceramic Brake Discs is not an easy process. I didn’t think there would have been so many complicated steps involved in making them. I was just thinking it was a slurry of ceramic material that was cast and machined. “This high performance material, made from a special mixture of powders, resins and fibres in a complex manufacturing process, has been used since the 1970s in braking systems
Most people enjoy a nice cool Slurpee every now and again. Even though I live in the Slurpee capitol of the world I had no idea how the machines worked. The video above makes it sound like the process is a bit more complicated than it is. I was thinking there would have been a bit more going on under the hood. I had envisioned some type of automation
