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.

Fishing line power transmission.
The first time I saw the Timescapes teasers I knew I would have to build a camera slider and explore the timelapse world for myself.
After a lot of research on this forum and a lot of late nights I have finally tested my motorised camera slider.
Lego gearset (don't laugh it works a treat) fishing line power transmission, aluminium door frame extrusion, Arduino micro controller and a 12v stepper motor. Note the termination of the fishing line with stainless steel thimbles and cotton covered hair bands, this takes up any harsh speed changes or direction changes.
All my demo timelapses have worked just fine.
The attached photos might explain the build better.

Microchip Technology's 8-bit PIC18F47J13 microcontroller (MCU) is the industry's first MCU to feature 128 KB Flash program memory in a 28-pin package. Also available in a 44-pin package, the PIC18F47J13 MCU features XLP technology for eXtreme Low Power consumption and mTouch™ capability for implementing capacitive touch sensing user interfaces.
Most of microcontrollers work within 5 volt environment and the I/O port can only handle current up to 20mA; therefore if we want to attach the microcontrollers I/O port to different voltage level circuit or to drive devices with more than 20mA; we need to use the interface circuit. One of the popular method is to use the Bipolar Junction Transistor (BJT) or we just called it transistor in this tutorial. For more information please visit www.ermicro.com/blog/?p=423

NYRR's NYE race values costumes, so I figured I'd throw a little light on my head. I bought a /relatively/ inexpensive headband and sewed the ends of the strip on the back, along with an Adafruit Gemma and a small alkaline battery box. Tomorrow I need only clip the threads and carefully disassemble the electronics to return it to a normal headband.

Microchip announced the expansion of its Low Power PIC® microcontroller (MCU) portfolio. Features of the new PIC24F “GB6” family include up to 1 MB of Flash memory with Error Correction Code (ECC) and 32 KB of RAM, making it the first 16-bit MCU in Microchip’s portfolio to offer such a large memory size. Also featuring dual-partition Flash with Live Update capability, these devices can hold two independent software applications, permitting the simultaneous programming of one partition while executing application code from the other. This powerful combination of features makes the PIC24F “GB6” family ideal for industrial, computer, medical/fitness and portable applications that require a long battery life, and data transfer and storage without the need of external memory, such as electricity metering, HVAC control, fingerprint scanners and gaming. For more information of the GB6 family, visit: www.microchip.com/PIC24FGB6-112315a
My friend wanted something he could install in his truck that would make it so his taillights would flash a couple times when he stepped on the brake, so they'd be more attention grabbing. Since that sounded like something I could make, I made one for his Christmas present.
This was taken using his present to me, a new lightbox. It seems there's perhaps a little more to using one of these than I previously thought.
Microchip Technology's mTouch™ Projected Capacitive Touch-Screen Sensing Technology and PIC16F707 8-bit microcontroller (MCU), featuring two 16-channel Capacitive Sensing Modules (CSMs) that can run in parallel for increased sampling speed. The MCU is available today for just $0.99 each in volume and, along with the mTouch projected-capacitive technology and development kit, enables designers to easily integrate projected capacitive touch-sensing functionality into their application with a single MCU, thus reducing total system costs and increasing design flexibility.
This is prototype tachometer i made for testing purposes. If it pass the test, it will be redesigned and integrated into final gauge with motogadget and gear shift indicator projects.
People have been asking me to actually talk about my feelings. There is a consensus that I don't talk about what I feel. Often you'll just hear me say "That's cool" and "Awesome" or "Sucks" and "Not Cool."
So let me say this, In the photo above, I feel poetry. I feel something like bpNicohols and Christian Bok. More than anything else I feel Jeff Knight's poem 'Peyote'. I don't feel Jeff's poem visually here, I feel it in what will become of this arduino board.
It will become the Living Day. And to quote Jeff's poem:
"Raindrops hit the windshield and sliver up the right.
Sometimes the raindrops spell words in languages that I have forgotten how to read.
It keeps running thru my mind that I should have brought my camera. I could capture all these drops all these words. I could take them home, I could study them later. I could learn to decode the complicated hieroglyphics of water on glass. But its not such a great idea.
There Isn't enough film in the world.
The hiss of the tires in the rainy dessert night smells like... coffee."
What inspires me to feel generally fits within two categories: Jazz or Poetry. Rarely both.
This microcontroller that I was working on, at this exact moment, was poetry.
To give you an idea of what my eyes see as Jazz: At a bus stop on 22nd and Walnut, Philadelphia, there is a row of residential buildings. From that bus stop, looking straight ahead at the sides of all these houses, jazz lives in the arrangement of the windows to rooftops places in the hands of time's mismatched architects and construction crew's need for conformity and price. It is, to me, the closest thing I have ever seen to John Coltrane's Ascension.
Some Dave Brubek's recording Impressions of Japan has most Center City's Spruce street in Philadelphia covered (when it is sunny and not too hot.)
On 13th and Walnut, sitting on the stoop and looking up to right at the skyline, The transitional period of Miles Davis's outward perception between "Kind of Blue" to "Live Evil" exist, depending on the time of day and cloud position. It is a feeling of the street and the feeling of it passing thru to the inside of me.
So, dear consensus, for the moment until I can better explain 'my feelings' you are just gonna have to live with Jazz and Poetry.

Russ connected an MCP4822 dual 12-bit digital-to-analog converter (DAC) to the fine Tektronix 2213A oscilloscope. A program (sketch) on the Arduino microcontroller drives the DAC and generates the image by steering the scope's CRT beam along the lines in the drawing (vector-scan). en.wikipedia.org/wiki/Vector_monitor
Russ has updated the software with some animation: www.youtube.com/watch?v=g0dRNZrtVjg

I finally got round to trying my hand at microcontroller programming. Following this instructable it was dead easy.
The main problem I ran up against was in the software. On Linux you need the ppdev module in order to have access to /dev/parports. In menuconfig it's Device drivers -> Character devices -> Support for user-space parallel port device drivers.
On Debian you need the following packages:
avr-libc binutils-avr gcc-avr avrdude
Your user also needs to be in the lp group for access to the parallel port.

I'm bringing up the gen2 circuit board.
This should be the sort of thing that a qualified electrical engineer would whip out in a matter of minutes.
But, I'm a programmer who likes to mess around with technology, so things sometimes take a little longer than they ought to.
Or I connect power to ground and ground to power. I do that sometimes, too.
But now, I can program this board to do stuff, once I get the LEDs all soldered up.
Soon, you will start seeing this board in my light art. :)
I have been working on it. First I got it to display simple pattern and then display text.
The people at MAKE blogged my little escapade. I clearly must make a gift for them. :)
Power adaptors to operate the microcontroller at 3.3V (top) or 5V (bottom). In both cases the 3.3V regulator and polyfuse on Calunium is omitted. By inserting one of the adaptors onto the auxillary power connector the voltage at which the microcontroller operates is easily selected. Power is supplied via the USB or FTDI connectors.
I built these so that I could power the board via USB for development and then fit a shield containing a boost regulator for battery powered operation. The combination of the right-angled connector on the stripboard and the polarized Molex connector on the PCB prevents the adaptor from being inserted in reverse (but not misaligned).
Arduino board designs use a variety of microprocessors and controllers. The boards are equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards or Breadboards (shields) and other circuits. The boards feature serial communications interfaces, including Universal Serial Bus (USB) on some models, which are also used for loading programs from personal computers. The microcontrollers are typically programmed using a dialect of features from the programming languages C and C++. In addition to using traditional compiler toolchains, the Arduino project provides an integrated development environment (IDE) based on the Processing language project.
From 1971. It used Nixie tubes for the display, Four digit with a key to shift the display to the other four. Unusual since it used a gold plated pad and stylus rather than keys. The price new was equivalent to $750 today.
