This is the Sanguino board. It is an Arduino compatible board based on the atmega644P. This page will tell you how to assemble one, probably from a kit that you bought somewhere. Once you are done, you'll have a sweet little board you can use for prototyping, hacking, or even for a permanent project.

The Sanguino has some awesome features like:

* 64K of flash space
* 4K of RAM
* 2K of EEPROM
* 2 hardware serial ports
* 32 GPIO pins
* 6 PWM pins
* 8 analog pins
* I2C, SPI, etc.

Personal 3D Printer rev.3 Beta

A powder-based 3D printer.
Build area: 15.25"L x 8.8"W x 6.6"D
Based on a Lexmark z715 inkjet printer.

This is a revision of a project started at University of Washington, under Prof. Mark Ganter, in the Solheim RP Lab.

Buttons
the 8 buttons per Arduinio gave us plenty of digital input pins. we no longer needed shift registers, and could use a simplified button circuit:
arduino.cc/en/Tutorial/Button

RGB LEDs
the lighting control came after much experimentation with very bright RGB LEDs. These were broken out to their own board with independent power supply. the Arduino could not drive the high powered LEDs and placement needed to be more flexible. The Arduino controls the RGB values via three PWM pins and a common ground. The values are reversed due to the odd relays we acquired. (ie {R=256,G=256,B=0} is BLUE)


Midi-out
midioutThe midi-out circuit is very straight forward with only two connected pins and a dangling ground. These wires are thin and continually come loose and cause trouble.




PCB
Fritzing.org has wonderful layout software that was used to generate the green image above. Soon they'll support eagle export, which will open up the design to any board shop. André Knörig has been an amazing resource by helping with the PCB routing and our submission into the Fritzmas contest.

The human powered internet cafe looks at the issues of renewable power generation and aims to educate users to the energy requirements of surfing the internet.

Users are asked to peddle the exercise bikes in order to turn a dynamo which would in turn power the computers. If users fail to peddle hard enough the computer monitors will begin to flicker encouraging them to peddle harder.

The thing would ideally be placed in public areas where all forms of society could view it and try it out for them selves, thus educating as many people as possible.

This is a base for a bicycle light

Addition of lights to my stage.

This is a derivative of Tinkering's thingiverse.com/thing:4526 with the endstop interface and the LED's removed (for now) using the robotshop.com/pololu-8v-35v-2a-single-bipolar-stepper-motor-driver-w-regulators.html . This board is designed to be easy to etch at home using the laser printer method so it can be made at home. I decided to make this guy because i fried one of my motor controllers by accident and the replacements have a 3 week lead time. Everything needed to make this can be picked up from radio shack in exception to some of the connectors.

If you want micro-stepping (1/16), and want to learn how to make your own PCB, this thing is for you.

* Will be finishing write up soon!

This is the new PRotos 3D-Printer designed on the base of Mendel/Prusa to build up a more versatile printer wich is expandable for different applications.
It is available as a complete kit at: shop.grrf.de/grrf-protos-3ddrucker-komplettbausatz-p-314.html?language=en
