In June, the Friends of Freeman Library received a generous $1,000 donation from United Space Alliance. U.S.A.'s donation supported the purchase of at least a dozen Sparkfun Inventor's Kits, which will allow older kids and teens to learn in a series of special library programs the basics of microcontrollers and how they work. Our CreatorSpace partners have also pledged help with instruction in these programs. Many thanks to U.S.A. and CreatorSpace for their continued support of Freeman Branch Library!
Ring shaped magnet is scavenged from headphone and it is glued into this Styrofoam piece along with piece of plastic pipe to reduce the traction. Washers are added to increase the weight.
The 8 pins PIC12F683 microcontroller is one of the smallest members of the Microchip 8-bit microcontroller families but equipped with powerful peripherals such as ADC and PWM capabilities. This make this tiny microcontroller is suitable for controlling the DC motor speed. In order to demonstrate the PIC12F683 capabilities and to make this tutorial more attractive, I decided to use the PIC12F683 microcontroller to generate simple and yet fascinating laser light show from a cheap keychain laser pointer.

(This board doesn't actually have USB, but it uses a USB port for power. I'm using this board here so that I can power it from my laptop.)
to run it around in the real world and get a little experience at high framerates. Controller and camera in old VHS tape box. Cheat sheet on left cover shows framerates as indicated on LED bargraph on controller. One button control system scrolls through bargraph. Each position is a different framerate except the last one which lets camera pause. If button is not pressed for 30 sec, it starts the indicated program.

Building a simple and easy microcontroller based robot is always a fascinating topic to be discussed, especially for the robotics newbie enthusiast. On this tutorial I will show you how to build your own microcontroller based robot which known as a photovore or you could call it as the light chaser robot using the simplest possible circuit for the microcontroller based robot brain, locomotion motor and the sensor.

An impulse purchase, and the physical design means it isn't that convenient to use, but interesting nevertheless ...
I'm still exploring the basic behaviors of transistors and capacitors, since I've never seen them explained terribly well beyond "capacitors store charge!" and "transistors switch and amplify!"
I'd gotten the Parallax BASIC Stamp HomeWork board for Christmas, but never got around to programming it since, well, it's programmed in BASIC, and the BASIC tokenizer doesn't work under Linux (well, not without some trickery, anyway). Compare that with the Arduino, which can be up and running in a matter of minutes, and uses C/C++ and the GNU toolchain.
I picked up the voltmeter at Ax-Man Surplus. It looks nifty and chunky, but unfortunately the needle isn't damped at all, so it wobbles a lot when voltage goes on or off. It's an EMICO NF2C-2137. The company is "Electro-Mech. Inst. Co. Inc., Perkasie., PA., U.S.A." Ah, the goold old days, back when the period was the "e-" or "i-" prefix of its day (and yes, there was really a period after "Perkasie" on the label)..
A good power supply is an essential subject to the microcontroller's base project; it's like a heart that gives a life to our microcontroller. Sometimes we take it for granted the important of having an adequate power supply to our microcontroller project and this can lead to the unexpected result or behavior from the circuit.

Talks and performances by people doing strange things with electricity
Fri 23 March 2012, 6.30-10pm with interval at the Showroom Cinema, Sheffield.
Dorkbot is a meeting of people interested in electric/electronic art in the broadest sense; robotics, kinetic art, microcontrollers, interactive art, algorithmic music, net.art... The only real conditions are that it is a bit strange and involves electricity in some way. It is really defined by whoever turns up, be it engineers who want to be artists, artists who want to be engineers, or the otherwise confused.
This MEGADORK event features a cabaret of talks and performances from among the UK's dorkiest, to entertain and amaze:
Paul Granjon - A strange performance from the world renowned self-styled robot artist.
Patrick Tresset - Talks about his drawing robot Paul (on show as part of the Alan Turing: Intuition and Ingenuity exhibition).
Daniel Jones and James Bulley - talking about generating live music from patterns of weather.
www.variable4.org.uk/about/intro
Sarah and Jenny Angliss - playing robot music from past futures.
spacedog.biz
Sergi Jorda - talks about the Reactable tangible tabletop music playground (which you'll be able to try out at the Central Library Saturday 24 March)
Dan Stowell - Demonstrates his use of the Risset illusion in techno music.
Silicone Bake - Live coded pop songs about love, death and counterfeit watches, where all lyrics are taken from spam emails.
Megadork is curated by Alex McLean.
Dorkbot started in New York, spread to London, and now dozens of cities around the world, including several active UK chapters; Sheffield, Bristol, Anglia, Newcastle, Cardiff and Alba (Scotland). Find out more at: www.dorkbot.org
