A few weeks ago we posted about Philips ‘Wake Up The Town‘ Experiment. Philips, with acclaimed director Doug Pray began an experiment at the end of October where they took the Philips Wake-up Light to the northern most town on the planet to see what effects it would have on the residents of Longyearbyen. Here, the sun doesn’t rise for 4 months so if the light can work for those living in perpetual darkness it can work anywhere!

Up until now, the campaign website has been keeping us all up to date on each of the residents’ progress, but yesterday the documentary was released. You can view the documentary on the link below.

This project is a device that accurately measures temperature inside a Styrofoam enclosure and compare it to external temperature. To accomplish this it is utilizing the 8 ADC channels of the ATMega48 and used its in-chip USART capabilities to send this data to a PC for logging.

It’s basically a combination of several projects (microcontroller, temperature measurement with LM335, USART serial port communication, data visualization) for minimal cost. (It’s part of a larger project, but it turned out so nicely that I think it’s a good project in itself!) Many of the temperature sensor pages out there are complicated (using segmented displays or LCD screens), don’t log the data easily, or use expensive components. Also, this project was designed (though not yet tested) to allow 8 sensors to be read simultaneously. Check details on the link below.

Ponoko announces a new digital way for custom goods to be designed, made and delivered.  It’s all about Personal Factory 4.

Introducing Personal Factory 4 (now with 3D printing)

  • Ponoko has launched Personal Factory 4, making it even easier to buy, sell and make custom goods online, with or without design skills.
  • The new 3D printing materials are durable plastic, superfine plastic, rainbow ceramic, stainless steel and gold plate.
  • Personal Factory 4 is the world’s only system offering instant online pricing to make your projects using a combination of 2D and 3D digital making technologies and open-source electronics hardware.
  • With no setup fees and no minimum order sizes, you can now make custom electronic gadgets, homeware, fashion and furniture in the comfort of your home – and sell them to the world.

San Francisco, CA – The future of products is here. Ponoko launched Personal Factory 4 today – making it easier than ever to bring product ideas to life from the comfort of the home. Everyone can now make custom goods with a few mouse clicks using 2D and 3D digital making technologies, and a huge catalog of open-source electronics hardware.

“Sophisticated design and manufacturing are no longer reserved for an elite group with big budgets”, says Ponoko CEO David ten Have. “Everyone has had a product idea at some point, and Personal Factory 4 gives them a place to make it real.”

Joe Grand @ grandideastudio.com is working on “Laser Range Finder” and shares his experience building it on Parallax Forums. He shows how he used a CMUcam to detect the reflected laser beam and calculate range based on triangulation.  He writes: [via]

I decided to go with the method of optical triangulation whereas the distance to a targeted object is calculated using triangulation with simple trigonometry between the centroid of laser light, camera, and object. The most compelling example is the Webcam Based DIY Laser Rangefinder (http://sites.google.com/site/todddan…m_laser_ranger) and my design is based, in theory, on this implementation.

Arduino shield board outline in gEDA format @ Low Voltage Labs. Eric writes:

I have been working on a few different shield boards for the Arduino platform. In an attempt to make life easier for myself I created a couple starter files for my future projects. The zip file below includes a schematic and PCB file in gEDA format. The board has the four headers and mounting holes for an Arduino shield board. I’ve decided to release the files into the wild for anyone to use.
