“When I gave a workshop at the School of Art and Design in Offenbach about building digital devices out of cardboard, the students asked me to build a machine as well. I always wanted to own a plotter – so I didn’t have to think too long about what exactly I’d build.”

“This report provides technical documentation for a prototype mobile environmental sensor that integrates with the Urban Tapestries public authoring system — the Feral Robot, version 2. Descriptions of the main requirements, as well as the steps in the hardware/software platform development are presented.”

“The robot starts moving automatically each time when the reset switch is pressed, the robot itsself finds an obstacle free path using the IR SENSORS. Whenever an obstacle appears, the robot changes its direction to avoid the obstacle and continue on its path.”

“When I first saw Crispin Jones Tengu, I was sure, I must have one. If you don’t know tengu and don’t want to follow the link, it’s a small face, made of LEDs, that reacts to music and sound.
It did not take long until I decided to clone this funny little device. All it needs is a microcontroller, an LED matrix and a sound sensor.”

“I noticed that most LED Matrix drivers on the market use shift registers to give a microcontroller the ability to control more LEDs than would be possible. Last year I came across the MAX7219 from Maxim Integrated. This cool little IC does all the work for you to drive a LED Matrix or LED Segment display.”

“The idea is to design and construct an electronic musical keyboard with some functions, effects etc,. This is my old school project and I remade and modified it. There are many hobbyist’s musical keyboard circuits around the net. Most design are based on 555 or some oscillator circuits. The limitation of these design are that this circuit generates only one tone at a time.”

Following last week’s release of the first lesson of PyroEDU’s new course, An Introduction To Digital Electronics, we are now ready to release Lesson 2: Number Systems. Again, this course is here thanks in large to our Kickstarter Backers, thanks to everyone who helped!

“How many times have you bought a Nixie tube at a garage sale or swap meet, only to discover once you got home that the tube was outgassed?…With a very high voltage, low current supply, one can build a portable ion source that can ionize the gas inside a tube, without even touching the tube. In effect the user ends up with a magic wand that will cause any cold cathode tube in its presence to light up.”

“We were inspired to build an ultrasonic security system for our final project by our housing situation this summer. Security is an important part of home, especially if we are going to share a house with prior strangers without a lock on our room door…..In case of intruders, it sends off a sound alarm and alerts the owner via email..”

“This years theme in "Sketching with Hardware" was Bionics. Consequently, the task was to rebuild or reuse a natural and biological method. Our team decided to imitate the behavior of Tetraodontidae – that’s the family of fish with the ability to inflate their body to a ball-like shape in order to defend itself. In an outburst of pure creativity, we named our prototype Blowfish!”

This might remind you of our Simple Motor Optical Encoder.
