ElectronicsNerd shows us how to reverse engineer an IR remote control signal. By understanding what type of signal is being transmitted out of the remote control allows a microcontroller to simulate the code to control the Hampton Bay Air Conditioner. "In the NEC protocol, the initial start pulse prepares the receiver IC for a data transmission at a particular rate, adjusting its AGC circuitry for the signal level excursions
This is a bed shaking alarm clock on steroids! This is even more jolting than my Fire Alarm Bell Alarm Clock! It uses two sources of air, a huge air compressor under the basement stairs and air from the car compressor. A computer controls a valve which starts bed shaking action. See the video below where it is tried out at a radio station. Thanks for the tip Stagueve.
Playing music using steppers is lots of fun, we have seen lots of stepper motor music in the past but this Super Mario tune sounds very nice. 🙂 Via: Adafruit "The sound you’re hearing is coming entirely from the motors. The motors are screwed into some pieces of aluminum from an old project to help them resonate. I’m taking requests for other songs to play. Currently, the information for
This Greenbox project is a beautiful way to save energy. Not only does it dress up the charging area but it also saves you money. When the phone is removed the wall wart charger is electrically disconnected. "As a design exercise, I have built a phone charging station that makes unplugging very easy and instinctive (with affordance playing a big role). So easy you don’t even notice it unplugs
This Arduino based Timelapse Photography Rig that Aonomus built is a great idea that will let you dig out your old digital camera and get a bit more use out of it. The Arduino microcontroller monitors a potentiometer and changes the time delay between pictures based on the dialed in value. There’s a LCD screen that shows the number of pictures taken and the delay between pictures. Finally to
With a few buttons, an LCD screen, an Arduino and a ioBridge, this project allows you to gather information locally and from the internet for instant display. In this example a local temperature sensor displays the local temperature while a internet based service used to get the temperature from another location. An online financial site is used to gather stock prices so that when you are in the kitchen
Justin Cole, Kris Williams, Chad Dickman, and Todd Sanderson of West Virginia University Institute of Technology just completed their Suzuki GT 750 Electric Motorcycle Conversion. Looks like it turned out real good. Even though the power of the motor that was removed would have been much more powerful the new 8 HP electric motor does get this thing moving at a nice speed. "Motor Briggs and Stratton Etek-R Model
