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.

A few more steps towards a usable system!
* Programmed FPGA to blink LEDs (the most important thing in any project)
* Wrote initial firmware for microcontroller, and it's now able to read/write the onboard flash chip, as well as program the FPGA all by itself :)
Next: some more work on the FPGA and probably initial motor control pretty soon. Well, that or smoke.
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.

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

This is the link to the schematic of the model R/C tank I am designing on a gearbox + Tracks & wheels from Tamiya. Full details with schematic at www.5volt.eu
Most of the holes are drilled to 0.8mm, but some are 1.0mm. In particular, the programming header, the I/O port connectors and the reset switch need the larger hole sizes.
Microchip Technology's MCP4706/16/26 non-volatile Digital-to Analog Converters feature buffered 8-,10- and 12-bit voltage output options and integrated EEPROM, and are offered in a miniature 2 mm x 2 mm DFN package, as well as a 6-pin SOT-23 package. The DACs are ideal for applications in the consumer and industrial markets, such as wireless microphones and mp3-player accessories; and applications such as motor control, flow measurement, temperature control and light control.
To give you an idea of the scale of these little blighters, the texture you see them "standing" on is not anything fancy, it's just standard copier paper. I was surprised how much texture you could see on a close up view like this

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.

Dit een gestripte versie van mijn DIY ArnoSync camera trigger. Deze versie is eveneens opgebouwd rond een PIC 12F675 microcontroller. Het is een versie met een lichtsterkere lens met een brandpunt afstand van 100 mm. Het apparaatje kan hierdoor een object in focus detecteren tot op 1 meter afstand van de camera.
Het is de bedoeling deze versie te gebruiken voor vogelfotografie. De gebruikte lasermodule is een IR (Infra Rood) versie welke ik nog beschikbaar had.
Alle onderdelen passen nog net op een mini breadboardje.
Het geheel is opgebouwd met een minimum aan onderdelen.
De aansluiting naar de Sony A6000 camera remote shutter input gebeurt nu via een robustere 3.5 mm chassis stereoplug. Voor de aansluiting naar de Sony A6000 synchro kabel is dus een extra 3.5mm naar 2.5 mm stereoadapter plugje nodig.
De voeding van het geheel gebeurt door een externe 5 Volt Mini Powerbank van 2600 mAh met schakelaar. Deze combinatie heeft een autonomie van ca. 100 uren. Door het gebruik van de on-off schakelaar enkel wanneer een detectie verwacht wordt kan er meerdere weken op een volgeladen Powerbank gewerkt worden.
-------------------------------------------
This is a striped-down version of my classic DIY ArnoSync camera trigger device.
This version is still build around a PIC 12F675 device. The mini system uses a better lens (100 mm focus) before the SFH309 phototransistor. The working distance to the object is now about 3 feet.
The used Lasermodule is an IR (Infra Red) type which I found in my junk-box.
All the electronics are mounted on a mini prototype breadboard. The connection to the Sony A6000 camera is done via a 3.5 mm stereo chassis plug. A 3.5 mm to 2.5 mm adapter is needed to mate the Sony A6000 external shutter release cable.
The used power supply is a small 2600 mAh Powerbank of 5 Volt with an ON/OFF push button switch. This allows power for more as 100 hours in continuous operation or several weeks when only switched on when an object is expected in the detection zone.
The LPC2119 board is mounted on a solderless breadboard, which is in turn mounted on some thin MDF. The chip is programmed via an RS-232 interface (cable on the left) from a PC running Linux. There's a bootloader on the chip that accepts new firmware according to a simple protocol over the serial link.

Microchip announced a new addition to its PIC12/16LF155X 8-bit microcontroller (MCU) family with the PIC16LF1554 and PIC16LF1559 (PIC16LF1554/9) devices. The PIC16LF1554/9 includes two independent 10-bit 100K samples per second Analog-to-Digital Converters (ADC) with hardware Capacitive Voltage Divider (CVD) support for capacitive-touch sensing. This unique ADC configuration enables more efficient sensor acquisition and assists with advanced touch-sensing techniques for extremely noisy environments, low-power applications, matrix keypads and water-resistant designs.

The MC13224 from Freescale is a ZigBee System-On-Package device. The three dies pictured are the microcontroller, radio, and flash memory.
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.
