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.

Simple prototyping boards for AVR microcontrollers. This one is designed for the Atmel ATtiny2313, and you can read more about it here. It's a complement to our earlier ATmegaxx8 board.
Having found that the ATtiny85 didn't have enough memory to hold my brainwave visualisations code, I put together a little Shrimp circuit to hook up the LED matrix and Bluetooth dongle. Attention data levels is visualised as red LEDs and meditation data levels as green LEDs.
Designers can integrate the MRF24J40MB transceiver module with the appropriate 16-bit PIC24 MCUs, dsPIC DSCs and 32-bit PIC32 MCUs, by purchasing the new MRF24J40MB PICtail™ Plus Daughter Board (part # AC163028-2), also announced today. This daughter board is designed to plug into the Explorer 16 Modular Development Board, which has available processor plug-in modules for all of Microchip’s 16- and 32-bit families. Additionally, the ZENA™ Wireless Network Analyzer is available to graphically display wireless network traffic, analyze the complete network traffic and graphically display decoded packets. All of these tools are available today at www.microchipdirect.com.
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.

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.

Version 1.1 of our open-source ATmegaXX8 AVR development target board. Read more about this project and download the design files here.
This is how I'm programming the AVR microcontrollers. I made a little carrier board to hold the standard 6 way socket which connects to the Adafruit USBtiny ISP. My breadboard power supply provides power for the micrcontroller and the whole lot is connected with breadboard wires. The LEDs on this board are for testing the software I'm currently working on. A short time ago the NRM had the Great Gathering and had six of Sir Nigel Gresley's A4 locomotives (including Mallard, which still has the steam locomotive speed record) all in one place. Two have now left but four still remain.
The mini-breadboard is just a handy way to connect the wires. It also holds a 100Ω resistor for the backlight LED.

The MC13224 from Freescale is a ZigBee System-On-Package device. The three dies pictured are the microcontroller, radio, and flash memory.
Working on a simple quad, it's been a project I've wanted to do for quite some time, and some random thoughts I had led me to try it now.
This is the main PCB, its roles are to distribute power, watch sensors (gyro, accelerometer, magnetometer) for stability, and provide control signals to the 4 rotors. Also has two central connectors for add-on boards; I am working on a board with an nRF radio and a flash chip for flight logging, the other could be used for other experimental features.
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.

This Sparkfun treat arrived late last week and I have been utterly consumed by my class until now. So I broke out the new Android IOIO board from Sparkfun, a convenient package all wrapped up and ready for easy access from the Dalvik platform. I have the board cabled to my Nook Color.
In this photo, the app on the left, "Hello IOIO" simply toggles the yellow LED next to the microcontroller. The RED LED signals power. This board requires external power and can power the attached Android device if there is enough current to power everything in the circuit.
It's a convenient platform. One can imagine using it as a versatile physical computing interface for common and inexpensive devices like the Nook or cast-off Android phones.
Microchip's 16-bit PIC24F microcontroller (MCU) family combines eXtreme low power (XLP) technology, low price and availability in low pin count packages for the most cost-sensitive consumer, medical, and industrial applications.
Lissajous figures are interesting curves that occur in systems where oscillation happens in more than one direction, for example when a pendulum hanging from a string moves in the plane.

Reflow = easy mode.
And this CNC board is significantly less painful to assemble than the previous one.
I got around to trying the circuit board I built yesterday and it works! Shown here is a PIC 12F675 microcontroller (mcu) running the mcu equivalent of Hello World, making an LED blink.
A microcontroller is a very small computer, here shown in the black package which is a little bit bigger than a quarter-inch on a side. They vary widely in physical size and capabilities and are typically used as the brains of control circuitry such as fuel injection systems, smart battery chargers, stuff like that, on up to fairly powerful devices like MP3 players. There's a hobbyist community centered around them and people come up with some pretty interesting stuff.
The idea behind a Hello World program is that it's the minimum necessary to show that you are able to develop a working program in whatever environment it is you're using. For most computer languages, you're able to assume some kind of device that can output text, whether an old-style terminal console or a web browser or whatever (and the traditional text, attributed to Brian Kernighan in the early 70s, is "hello, world.") With a microcontroller, though, the simplest setup doesn't have any text output. Instead, a light-emitting diode (LED) is connected to one of the chip's pins and a program written to make it blink. Blinking is the simplest way to show that the program is running - steady-on might happen by accident depending on how the circuit is wired. The blink shows both that the program is executing properly and that it's running at the speed you expect.
The way MCU development works is that you write the program for the little chip on a PC and send it (nowadays) through a USB cable to a device called a programmer. The programmer configures the MCU's memory to contain your program and off you go; newer programmers like the PICkit 3 pictured here are also able to let you run the program one instruction at a time and observe its behavior on the development PC. The circuit shown here doesn't support that, but I don't use that functionality much anyway - my projects tend to be more complex than Hello World but not hairy enough to need that kind of debugging power.
I built this little setup so that I could make MCU-based projects for my new year 2012 resolution of making some object every week. One problem I've had with my electronics hobby to date is that I never finish anything; it's enough for me to show that I can get something working, then I don't take the last step of putting it in some sort of durable form that can then be presented to someone and used. Mostly, that's not really a problem, since there isn't any obligation for a hobby to produce useful things. But I would like to actually put some stuff in peoples' hands.
