I am a huge Tesla fan. Anytime I read anything about wireless power applications I get very excited. Coils and resonance frequency drives me nuts. Check out bea.st’s web site: On the main page is one such project that deals with Magnetic Levitation using Hall effect Sensor Feedback, and Matched resonant wireless power transfer Check out the video links right under the first image. Detailed information and schematics are listed
Here is a cool project that you can build from a few parts that will allow you to power fluorescent lights with a 12 volt battery. This low cost project even teaches you how to wind your own transformer from salvaged parts. This link is from a interactive electronics e-magazine stocked full of electronics projects and tutorials. There is also a basic electronics course and micro-computer programming course that can
By adding a microcontroller and some white LEDs this normal everyday clock is transformed into a very interesting and unique clock. “KapteinKUK have modified his wall clock by adding 12 LEDs controlled by ATtiny2313 microcontroller. LEDs are flashing randomly driven patterns with some variable intensity driven by PWM channel.”
I have been thinking about hacking my boring door bell for years. I want want mine to knock on the door when the door bell is pressed. The guys over at PopSci have come up with a cool way to make what they call a Ding Tone Door Bell, have a look it looks like fun. 🙂 “If you’ve got a spare MP3 player laying around your home, it’s time
George from AmateurLogic.TV puts together a surface mount software defined radio kit in this episode. “George builds the Softrock Software Defined Radio. Jim introduces us to the International Beacon Project. Tommy demonstrates and explains all about the amazing Ham Radio Deluxe. Peter is back with a mountain top review of the Degen DE-1103 shortwave receiver.”
Jordan Crittenden and Edwin Lai built this DIY Polygraph, their goal was to construct it for $50.00. “The basic design of the polygraph is shown in the diagram to the right. The four analog circuits: plethysmograph (pulse rate meter), GSR meter, breathing rate meter, and audio preamplifier, are attached to the first four pins of the Mega32 analog to digital converter (ADC). The polygraph can then be run in one
Tobias Hocke has built a cool binary clock that is based around the ATmega8515 microcontroller. Slap in a 9 volt battery and push a few buttons to set the time and you have a clock that very few people can read. Check out his site for a full schematic so you can build your own.
