"…Shortly after the handheld Open SciCal got picked up, I got an order for a few Open SciCal’s, hand-made, with the wi-fi attachment, and to be delivered to an address in downtown Manhattan. I did a little more research, and it turns out that they’re going to be used by an actual trading firm on Wallstreet…..I asked for an example in source code, and here it is – very simplified, and coded up for Yahoo finance…"

"…In order to solve a debate, the facility wants to track the released fawns to monitor their progress. If the fawns are alive three weeks after release then it is obvious that the herd is feeding them. The facility has a limited budget so I am building the tracking devices for them. The tracking collars will be GPS based so that the facility staff will not require advanced radio signal tracking skills."

"…I decided to give my Raspberry Pi something interesting and colourful to do – light painting. A happy day of geeking saw my brother and I pull together a wireless remote-controlled, battery-powered, Raspberry Pi light painting robot. It’s not perfect, but we think the initial results are pretty good for a day’s work and I thought I’d share some notes and photos in case anyone else is interested."

"To test whether this was feasable I decided to create small brakout boards for a multiplexer and an atmega. I managed to get a friend interested in this, so together with Marty I designed some simple 1 to 1 pin breakouts for the two ICs."

"Today I fabricated the PCB for GNUduino (Arduino made with gEDA). I used screen printing to transfer the PCB layout. Screen printing is another way to transfer the PCB layout to the copper clad instead of the conventional toner transfer method."
