The ProjectCam is a digital camera in the space which can be used for taking photos of projects and things going on at the space. The holder was designed by Jake Howe and is designed so it is easy to find and use but hard to lose.

If you see something interesting then pick it up and start snapping.

It lives on a hook near the big H in the studio.

It contains a SanDisk Eye-Fi, which is a wifi enabled SD card. This has 8GB of storage but also uploads photos to ****Where do these photos go?***** Details for setting up the Eye-Fi to upload direct to Flickr are here:

Its quite hard to take photos of a camera. Hence there are no photos yet.

-The joule thief is a very simple circuit designed to power an LED from a battery with a very low voltage. It is designed to squeeze out energy from a battery which might otherwise be thrown away. Most devices which use AA and AAA batteries stop working when the battery voltage is below 1V. There is still some energy in the battery, down to around 0.8V. The Joule Thief is designed to step up that voltage to a useful level, such as to supply an LED. LED's need around 2.2V or higher (3.2V for white and blue LEDs) but not so much current (around 10-30mA). Basically it is a DC to DC converter from 0.8V to around 3.5V.

-These can be built (check the first link) from an NPN transistor, ferrite ring, resistor and the LED and a bit of wire. Lots of these parts can be found on old circuit boards, especially computer mother boards, power supplies and broken compact fluorescent lights.

-We found that from 3 different ferrites taken from different devices, one did not work, although that could have been my wire winding skills going wrong, so this might take some experimentation.
