Microchip Technology's PIC18F47J53 8-bit USB microcontroller (MCU) features XLP technology for eXtreme Low Power Consumption, up to 128 KB Flash program memory and 4 KB RAM, offering plenty of code space for Microchip’s free USB stack, and for application code.
Connections on top side of board. Total - 8 wire jumpers.
7 wire jumpers are marked yellow.
Place of jumper #8 is determined by value of voltage, that should be applied to fans.
For 5V fans, green jumper (W1 on schematic) should be soldered,
for 12V fans - red (W2).
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.

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
Lovebytes 2012 - Digital Spring
A Festival of Art, Science and Technology
22-24 March

These are three of my electronic projects. The top one has been going for over two years recording the weather and my motion lights and gate. The bottom unit records the data on a SD flash chip in comma-separated format.

Testing out an ADXL330 accelerometer, and interfacing it to an AVR microcontroller. Read more here
Arduino UNO was one of the first ever circuit portraits, way back in 2013. This is a new edition with an extra layer and a bit more finesse.

ICSP 5-pin header. Pin #1 is on a right side.
2N7000 MOSFET transistors. To avoid solder bridges between leads of transistor , use plenty of flux during soldering. Check all neighboring leads for short circuit with continuity meter.
Here is the MSF Receiver test bed in 2022, in a conveniently-sized shoebox which helps keep all the bits together.
Here we see the receiver module in a litte cheese carton.
I have managed to damage the receiver module (due to some ham fisted fault finding) which means it will only now function with a much reduced supply voltage, which explains the LM317 in the container.
Then on the main board I have had to add a voltage shifting circuit to lift the reduced output voltage to one which will drive the Arduino which runs the latest version of the code which may eventually find its way into the "built" unit.
There are a few redundant left-over parts from earlier projects.
Definitely a bit "Heath Robinson"!
Have you ever thought that most of our perception about the robot is based on the Hollywood movie! The well-known 3CPO and R2D2 from Star Wars until the little cute garbage compacting robot named WALL-E; all of these machines are example of our dreams or should I say our quest to what we all think about the robot should be. Although the robot that we are going to build here is still far away from the technologies shown on those movies but at least it will give you an introductory to the robotics world. for more information please visit www.ermicro.com/blog/?p=983

Dropping the remote broke the trace from the left top button to the microcontroller TXM TX-2B ZYX16EA.
As the electronics hobbyist one of knowledge that we have to be familiar with is how to make our own printed circuit board (PCB). Making our own simple single side PCB actually is not require a sophisticated technique and technology as you might think, instead most of the required materials is already available at your home.

Pellet stove controller. Populated PCB.
I was constantly burning out my pellet stove ignitor. An external thermostat tends to minimize the temperature fluctuation and causes the stove to run short cycles. The ignitor runs for 20-minutes every cycle.
This controller add more hysteresis to the temperature control. It continues to run the stove for a period after the thermostat stops calling for heat. When the thermostat again calls for heat, it adds a delay before starting a new cycle.
