If you need to monitor a fan on a piece of equipment this PC Fan Failure Alarm from PCB Heaven should fit the bill. The RPM monitor line is used to determine what the RPM of the fan is and if it falls below an adjustable threshold the alarm is tripped. Heat buildup due to a faulty fan can do some serious damage in a short time, this simple circuit
Luis sent in this neat game that he built using an ATmega 328 microcontroller. He is from Honduran and this system was featured as the first video game system made in Honduras on several local newspapers and some local TV programs. “This is a monochrome game with monaural sound I created using an atmega328. The circuit has 3 MCUs (One for composite video, the IR receiver de-codifier, and the last
Our friend Edo who brought us the cool 64 RGB LED Table has just installed some stair lights into his stairwell. Edo has started a new Youtube account which will contain all of his interactive furniture creations. I spoke to Edo about his creation and he didn’t know about the stair lighting controller that we sell, all I can think is that creative minds think alike. 🙂 Our original prototype
Owen sent in his cool Touch Screen Hack for his TI 84 Plus Calculator. He is using an Arduino to read in the data from a Nintendo touch screen, the touch data is then sent to the calculator’s serial port so that it can then graph images based on where the screen is being touched. Did I mention that Owen is 16! I am trying to think what I was
Thanks to Senario (the makers of Zibits) for sponsoring the contest this week. They will be providing 4 lucky contest winner a Zibits robot. Have a look at the video below, the robots are IR controlled and I thing with a bit of hacking they could be sent random forward and turn commands which would make your cat or dog go crazy. “Product Details Mini Collectable Zibits come to life
The time will come when you need to have some distance between sections of your project, or you just need a remote way of interfacing to it. Peter Jakab has developed this Infrared or Radio Remote Control Project which should fit the bill. If you have line of sight you can use IR to create the link, if you don’t you can simply use RF. The existing design has a
Looks like the hardware on the Rigol DS1052E Oscilloscope is identical to the more expensive 100MHz DS1102E version. Nice thing about that is with a few commands you can make your 50MHz scope into a 100MHz scope!
