FLORA ExperimentI’m starting to experiment with FLORA from Adafruit and clothing.
The platform is easy to use so far, but for some reason I have to unplug it from my computer and plug it back in before a sketch will upload.

The idea here is to use a light sensor to turn on an LED in the suit jacket pocket when it is dark outside.  Potentially I might put more LEDs under the collar.

Some random thoughts or ideas in this vein. Can you use snaps as an on/off switch?  Can zippers conduct electricity and if so, can they be used as switches as well?  How about metal buttons? Assuming you can by waterproof LED strips, how about making a bicycle turn signal jacket with buttons / activators in the garment cuff?  Or a running jacket that lights up at dusk so drivers and other people can more easily see you? How do you make any of this removable so the garment can be washed?

Another vein would be to include GPS and Adafruit does make a GPS sensor for use with FLORA.  We especially like the No Place Like Home Shoes.  The GPS is activated by a heel click and indicates the way home through LEDs.


Rolling Bridge

October 13, 2012

A little off topic here, but recently I was in London and saw the amazing rolling bridge. This is a really neat feat of mechanical engineering.

The bridge uses hydraulics to roll up on itself so a boat can go into the waterway and turn around or stop and unload cargo.

Lucky PandaI finally finished this project. I had previously made a much smaller version with only a LCD screen, but no printer as they were not available at the time.

First I started out getting the thermal printer to work with an Arduino and a LCD screen.

Weather Station Project

August 3, 2011

My latest project is a weather station.  I have made a base station using a LCD screen, Prototino (an Arduino with holes for soldering), Xbee series 2 radio and an old cigar box.  Previously I had the LCD screen breadboarded to a regular Arduino and it constantly gave me problems.  Since I devised a way to solder it into the Prototino is is very stable.  I am using pre-crimped wires and crimp connectors to go from the LCD to the Prototino.  This makes the Prototino easily detachable from the LCD screen.  I am also heat shrink wrapping the wire end that get soldered into the Prototino as the metal ends are fairly long and may bump into each other.

The other half to this project is a Xbee series 2 radio inside a Stevenson shield that is outside my house.  Inside it is a temperature sensor, a light sensor and a humidity sensor.  As you can see in the picture,  I can’t seem to get the humidity sensor to work right with the other sensors.  More testing is needed.

Eventually I hope to add more sensors like an an anemometer, rain sensor and wind direction.
