" I used a 434MHz transmitter and receiver from Sparkfun, and had great success with these cheap devices. I also used a simple LM34 Fahrenheit temperature sensor, two Arduinos, and a two-digit LED display to show the temperature at the receiver end."

"LCD2USB is a open source/open hardware project. The goal of LCD2USB is to connect HD44780 based text LCD displays to various PCs via USB. LCD2USB was meant to be cheap and to be made of easily available parts. It is therefore based on the Atmel AVR Mega8 CPU and does not require any difficult to obtain parts like separate USB controllers and the like."

"Like the Arduino, the USB6 allows you to control robots, make electronic instruments, talk to sensors and interface with the internet. The main difference is that you *buy* an Arduino. You make a USB6. This is good for people who are more interested in the hardware side of things. For example, would you like to learn what capacitors look like? Would you like to try out some board etching techniques, especially alternatives to Ferric Chloride, like Hydrogen Peroxide, etc?"

"For the last several weeks I’ve been hacking together a small prototype of a microcontroller (ATTiny2313)-powered prime number generator. I can finally say that it is complete, functional, and elegant. The name says what it does, so I won’t waste time describing it."

"The basic idea is when making a purchase with a credit or ATM card, the transaction information is automatically packaged and sent to a webserver where it can be logged in a database. A web interface would then allow consumers to log into their accounts and view their transactions online all in one place."

"So I’ve done persistence of vision displays before; there’s really nothing new there. The challenge this time was to make it small enough to fit on a 72mm longboard wheel, and to make it cheap enough so that I could mass produce it and sell it to folks in the area."

"The ATTiny Candle is an LED candle. It uses a high brightness LED and some software to mimic the look of a traditional candle without the dangers associated with an open flame. I imagine they could be useful as movie props where you cannot afford to have a candle go out during a take or in your home in places not suitable for traditional candles such as in a wall niche or alcove."

"8-channel approach to IR detector sensor circuit is realized with ATmega8 microcontroller. I2C bus (TWI, SMBus) are measuring through the obstacle detection, designed for mobile robot. Approach reflects the beam of infrared light detector circuit based on monitoring works."

"In my new Dacia Duster is missing unfortunately an outside temperature indication. A finished thermometer with LCD did not separate from there while the contrast with sunlight usually particularly is. I had still alphanummeric LED display in red there for this project in the best way am suitable. As microcontroller i used a ATTINY 2313. The temperature sensor is a 1-Wire-digital sensor, thus the alignment of the sensor is void."
