"Piccolo is a low-cost kitset device that uses servos to create a mechanism for tinkering with or developing for basic 2D or 3D CNC output. Applications range from simple drawings, generative designs and data visualations, to small scale laser cutting or 3d printing, depending on the tool head used. Piccolo’s small size, low power and low cost makes it easy to use in almost any environment and in multiples."

"The term ‘mixed-signal’ is usually reserved for circuits and ICs that process both analog and digital signals. In that sense the title ‘A mixed-signal LED clock’ is perhaps misleading since this is a digital clock from beginning to end. However, the readout is analog and since the beast had to be given a name, I a called it my ‘mixed-signal’ clock. "

"This is a simple sound generator based on 8-pin SD Audio Player. It is built with an Atmel ATtiny861 microcontroller and an SD memory card. The tiny861 has fast PWM outpus like tiny85 so that it can generate clear sound compared to any other AVR chips. On 20-pin device, many GPIO pins are available. It enables to control the sound generator by external signals."

"The Wireless Power Meter is a simplistic ATmega88p and ZigBee/XBee based true V-I power meter. AC voltage measurement is made from the rectified signal of a step-down transformer, and current measurement is made with the pass-through Allegro ACS712 Hall-Effect sensor."

"EEG’s getting big! Since it’s been in my project stable for a while, many people have been asking for advice, so here’s a primer with pretty much everything I’ve written on the subject and some previously-unpublished FAQs."

"I always wanted a fast way to make PCB prototype before send the project to a fabhouse and wait 2 or more months to see the result. This is why I built this CNC, it’s made from cd-rom parts and was inspired viewing some similar projects on internet."

"An autonomous robot requires both: actuators and sensors. Actuators are responsible for moving and sensors help to measure a physical quantities. Without actuators a robot cannot perform any practical task. If your robot doesn’t have sensors, then it’s blind. In our case, actuators are two motors for moving of the spider. Proximity sensors help to perceive distance to obstacles."

"The mobile line follower robot is a type of mobile robot with only has one specific task which is to follow the line made with black tape over the white background or vise verse….What makes this LFR is so popular, I think because of its simplicity and yet it could be used as the teaching tools of how we could implement the industrial standard control system such as the PID control system on this robot."

"The objective was to provide a low cost gear position and ambient air temperature display for my 2009 Suzuki V-Strom (DL1000). Also, to (mostly) open source the project design with documentation so that anyone with basic electronic skills can duplicate the design for their motorcycle."

"This easy-to-build electronic device allows you to take a screenshot of your calculator display and show it on an NTSC or PAL television set. Unlike the TI-Presenter this does not require a special calculator or a USB adaptor; it uses the 2.5mm link port."
