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

This is our TinyG Stepper Controller Board. I tossed some code up on the xmega to test inputs from these "encoder ports" All I am doing is putting 3v onto each pin and it turns off the led that corresponds to the port.

Dorkbot Bristol, December 2008: Drew operating the dropper on his high-speed photography rig. It's based on an Arduino and triggers the camera shutter and flash at precisely the right moment to capture the splash.

Stuff from Adafruit.

It's an alphanumeric persistence of vision display. This photo was taken by setting the camera on self-timer with a 2.5 s exposure. When the picture started going, I just walked through the frame at normal speed. Ha! I'm invisible.

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.

Microchip and Digilent's chipKIT(tm) Development Platform is the first 32-bit-microcontroller-based, open-source development platform that is compatible with Arduino™ hardware and software. More information is available at: www.digilentinc.com/chipkit.

The Rainbow Lighter V2.2 completed, it took several evenings to get it all put together. I grabbed an Altoids tin from my bits'n'pieces supply bag for the 9-volt battery holder.

 

There is a piece of 1mm black foam (neoprene) attached to the back of the circuit board. The Altoids tin attaches to the foam with a piece of velcro to hold it in place.

 

Thanks to El Endemoniau for inspiring me to create my own Cr@p Lighter.

 

My version is using tri-color (manually controlled) LEDs so each individual LED is three LEDs combined. Each one can be lit up to be red, green, or blue...the cool part being that you can then generate different colors using combinations of these three colors. For example, red & green = yellow, green & blue = cyan.

 

The next step is to develop software for the AVR microcontroller so I can display patterns and text. ;-)

The four-member PIC24FJ256GB210 microcontroller family integrates USB for Embedded Host/Peripheral/On-the-Go and 96 Kbytes of RAM. This large RAM enables the buffering of sizeable amounts of data and better overall throughput, for applications such as Ethernet connectivity, remote sensing, data logging and audio streaming. It can also be used to store generated images or data for dynamic content, such as real-time, remote sensor data graphs. In combination with Microchip’s free USB software library and TCP/IP stack, these MCUs lower system costs and footprints in a broad range of industrial, instrumentation/measurement, medical and consumer applications.

Microchip's PIC12LF1840T48A is the first in a family of single-chip devices that integrate an eXtreme Low Power (XLP), 8-bit PIC® microcontroller with a sub-GHz RF transmitter. The PIC12LF1840T48A’s combination of features in a single, 14-pin TSSOP package makes it ideal for space-, power- and cost-constrained applications, such as remote keyless entry fobs for automobiles, garage doors and home security systems, as well as a broad range of other home and building automation systems. Additionally, the device is optimized to run Microchip’s royalty-free KEELOQ® advanced code-hopping technology, a proven security technology used worldwide by leading manufacturers.

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
