Microchip Technology's 8-bit, low-cost, Enhanced Mid-range Core PIC16F1516/7/8/9 and PIC16F1526/7 (PIC16F15XX) microcontrollers (MCUs) feature eXtreme Low Power (XLP) technology for sleep currents down to 20 nA, which lowers overall power consumption and extends battery life. An on-chip 10-bit Analog-to-Digital Converter (ADC) with up to 30 channels enables mTouch™ capacitive touch-sensing keys and sliders, and high-resolution touch-screen designs. Up to two each of EUSART, I2C™, and SPI ports enable communication with on-board peripherals. They are ideal for cost-sensitive applications in the consumer (e.g. DVD players, cell phones, MP3 players); automotive (e.g. dashboards, gauges, on-board sensors), home appliance (e.g. washing machines, refrigerators, TV remote controls), and other markets.
First draft of a circuit for connecting a CD-ROM motor to an Arduino so that it acts as a rotary sensor. I want to make it into a spinner control, rather like those which are used to control video playback. Normally, the Hall-effect sensors are connected to the motor driver chip and control the commutation. I've wired them to a comparator chip (TLC3704) and then to the Arduino.
Participants in the first of our two-part microcontroller basics class, presented by Dave O. of CreatorSpace, enjoyed the excitement of circuit building, making lights blink and sensors react by entering and changing only a few simple lines of computer code. Both the kits and the laptops were generously donated by United Space Alliance.
An Atmel ATtiny24 microcontroller drives an R/C servo wich in turn rotates a line LASER taken from a LASER level.
The microcontroller runs a software real time clock and turns the servo and the line LASER to mimic the shadow cast from the style of a sundial as the time goes.
Looking a little worse for wear, looks like it's been left outside! I love this little WiFi microcontroller, it's so versatile! This was the core of my breadboard Geiger counter project.

Microcontroller, thermal printer, stainless steel. 2016
This work is designed to undermine the vital but patronizing “Harz IV” agenda of the German government in which self-employed individuals must send in records of their expenses in order to verify the necessity of support. Made of stainless steel, this unobtrusive machine is suited for the harsh environments of the streets. It generates receipts for random items, quantities, and sale amounts. Each receipt is printed on thermal paper like an actual receipt and could be sent to the authorities.

Microchip's PIC32 “MX1” and “MX2” MCUs are the smallest and lowest-cost PIC32 microcontrollers, and are the first PIC32s to feature dedicated audio and capacitive-sensing peripherals. These latest PIC32 MX1 and MX2 MCUs also feature USB On-the-Go (OTG) capabilities, making them ideal for developing audio accessories and other applications in the consumer, industrial, medical and automotive markets.
The idea behind this project is to run a microcontroller and its accessories (LCD's, high speed ADC or DACs, any sort of ANYTHING really) from a single AAA battery. The devices can be tiny and compact, and the MSP430 will last a bazillion years on a single AAA cell anyway. Yes, it does work after only a good 5 hour lab session!
So this is a boost converter that can take anything between 0.7v and 3v and will output a 4.8v signal (for use in 5v logic, LCDs, and backlights) and a 2.5v output for powering the actual microcontroller. It can also output 3v with a resistor change and if I need to I'll add a pot to give a wide range of values.
The board is a lot bigger than it needs to be, but this was more of a proof of concept because I had never built a power converter before. If I was to put this on a PCB I would be able to make it VERY small (smaller than a second AAA cell, wich would validate the effort!)
The Serial Peripheral Interface (SPI) is one of the popular embedded serial communications widely supported by many of today’s chip manufacture and it considered as one of the fastest serial data transfer interface for the embedded system. Because of its special in/out register configuration, the SPI master device could transfer its data and at the same time it receive a data from the SPI slave device with the clock speed as high as 10 MHz. Beside its superior data transfer speed; SPI also use a very simple data transfer protocol compared to the other serial data transfer methods.

Microchip's dsPIC33FJ16 “GP,” dsPIC33FJ16 and PIC24FJ16 “MC” devices enable advanced control for cost-sensitive general-purpose and motor-control applications.
This is the replacement hardware. The core is a PIC18f4550 controlling everything with a 20Mhz oscillator to supply the PLL for the 48Mhz required to run USB should i ever get round to implementing that. The CPU runs at 8Mhz from the internal osc. There is a MAX232 to drive the serial port and some transistors to switch relays for the spindle and that is about it. the 9 pin plug floating there is just to allow me to debug the board when it is not in the machine. The screw terminals will be for the motor and the spindle encoder but the encoder is not implemented in code yet so I haven't connected it. Some fly back diodes for the relays, caps for the MAX232 charge pumps, transistor base resistors, LEDs for debugging, ICSP plug and some wire make up what is left. Not really all that much there. I will probably add another transistor and 2 resistors and a cap to this to amplify the PWM signal since the PIC gives out 5Vpk-pk and the PWM in the control box needs 0-10V in. (I know its a bit silly generating an analogue voltage from a PWM output only to use it to control another PWM drive but this way it is a direct board swap.)
Without a computer or a microcontroller, time machine: inner landscape is interactively controlled by five-fifty-five timer chips and photo resistors which advances slide show imagery and amplified sounds via analog and digital sound circuitry.

The Secret Project Circuit Bward She Works! Yhey!
Seen here resting upon The Development Environment of Kings.
This is the first time I've attempted to make a circuit with a surface-mount microcontroller. In this case, a SOIC version of the Atmel ATTiny861. How very encouraging that it works and did not splode!
I goofed and forgot to take a picture of the underside of the assembled board, which is where all the interesting bits are. But you know what? I made two of them, so I can take a picture of the guts after assembling the other one. Or I could just remove the high-tech protective backing on this one, which - like the one on the Ad-Hoc Power Supply - is a piece of cardboard held in place with electrical tape.

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.
