"I decided to explore the more advanced features of XBee radios by building a remote temperature sensor. You can get quite a bit of control over an XBee radio without a microcontroller at all. You can configure the radio to send sensor readings at particular intervals when it detects changes on certain input pins."

The Beavis offers everything you need to wire up 25 sound-shaping circuits, from parts to multi-meter to integrated breadboard. The OpenStomp Coyote takes a different approach, with a programmable processor and Windows visual patching software.

Here is another twist on the POV clock idea, a POV globe. Although project details are sparse, the creater of this awesome POV glove has put up many detailed photos of his design along with videos of it in action to give you a feel for how it works. A very interesting project!

“Using an add-on card to the already existing avr ethernet board we build a weather station. That is: A weather station with a build-in webserver…The system is modular. You can either build a pure Ethenet weather station or an Ethenet weather station with an additional local LCD display.”

“I have always wanted to create a VGA generator. It has been a personal goal of mine for some time. Over the past couple of weeks I toyed with the idea and finally decided to implement one. I decided to implement it as a framebuffer to allow for general purpose display rather than application specific display. I implemented my own small colour gamut to be memory and CPU efficient.”

This week at PyroEDU we’re going to be adding another lesson to the Analog Electronics course, called Zener Diodes. Here’s a quick intro of what this PyroEDU lesson is all about:

The zener diode is a special type of diode that allows current to flow through it in either direction, however only at certain voltages. In this lesson we will learn how zener diodes affect AC and DC signals and perform some experiments to see those effects.

“Clappidoo sits quietly and will not bother anyone, unless somebody carelessly puts an object in front of him. Clappidoo will then wake-up and, depending on his ‘mood’ of the moment, will either be: Angry, Happy, Confused or Flirty. Clappidoo will go trough all these moods at random, and will go back to sleep if you remove the annoyance in front of him.”

“I’ve made plenty of LED Throwies in my day but I only recently discovered Karl Lunt’s low power LED firefly project. I was immediately inspired to make my own LEDfireflies. Unlike LED Throwies which will only last 4 or 5 days per battery, these LEDfireflies utilize ATTiny AVR microcontrollers and the LED as a light sensor (cool!) to get several weeks of flashing on a single battery.”

“This project started about 8 months ago in January 2010, when I saw that a surprising number of people were making ROVs at home. Though very few had footage of anything interesting, it certainly proved the concept was viable. I’ve always been fascinated and fearful of the ocean, so this seemed a great way to explore the depths without having to personally go where the sun doesn’t shine.”

“The clap sensor is a simple circuit that incorporates a PC microphone, a microcontroller, and an output.I chose the ATtiny84 microcontroller for this project because I’m familiar with the AVR architecture and I have access to the tools to use it. I bought the ATtiny84 in its SOIC-14 packaging. ”
