Arduino key tapper keeps VPN login from timing out. Taps keyboard every 4 minutes. Uses small servo motor to actuate arm that hits shift key.
Acrylic case from Pokono. Other parts/servo from Sparkfun.
There might be better ways of doing this by faking computer that arduino was keyboard or mouse, but this was the easiest. :^)
Arduino bluetooth project gets a camera. One 4N25 opto-isolator to turn camera on/off and one to take pictures. Wrote an Android phone app to talk through bluetooth to Arduino to control camera.

FAST LIGHT • May 7 + 8, 2011, 7 pm - 10 pm
Contemporary pioneers in art, science, and technology have come together at MIT to create one of the most exhilarating and inventive spectacles metro Boston has ever seen.

We have a pretty perfect view of the foothills just north of Boulder where the weather tends to come in from.
I'll get another one when a huge storm brings some snow in; it's quite a sight!
also: I FUCKING HATE WORKING WITH VIDEO ON LINUX. ENJOY THE BLACK BORDER.
The Leiger is a geiger counter, GPS logger, and dosimeter all wrapped up in one. It was designed and built by Rob, host of the SparkFun weekly product videos. It's always a good idea to keep an eye on radiation levels when traveling to Chernobyl.
Never a dull moment at SparkFun on Friday afternoons.
Leftover pumpkins from Halloween being thrown off the SFE roof.
Kinda NSFW language?

(Inspired by the AWESOME Button.)
(Also note, that resistor inline is not needed! The Teensy has pullup resistors built-in!)
This was actually dead easy. I'm using a XBee Explorer (no USB).
Connect arduino pin 1 -> DIN on xbee, arduino pin 2 -> DOUT on xbee, 5v and GND. That's it!
Though this one is based on a arduino mega, it'll work on any board, and doesn't need any extra code.

3rd iteration of "Counter Intelligence" project. For best results with Maxbotic rangefinders I'd recommend the Lilypad. Parts from Sparkfun. Backlit 2x17 driven from serial interface of Lilypad.
3/4 view of soda / beer vending machine prototype. To be cut out of 3mm acrylic and actuated by an arduino.
The idea behind this is that most college students buy a mini-fridge freshman year and then sell it sophomore or junior year. This way they can turn their freshman mini-fridge into a senior beer vending machine!
With a rectangular hole cut in the front of the door and an acrylic tray for the delivery, this can convert any mini-fridge (or regular fridge!) into a party favorite. Two units would fit into the smallest of fridges, and a full size one might be able to support 8 or more!
UPDATE: study from Indiana University:
news.indiana.edu/releases/iu/2014/09/slow-walking-sitting...
Given the way science is not well vetted by the media, I'm concerned that this "sitting is killing you" movement is just another fad.
www.npr.org/2012/05/09/152336802/stand-up-walk-around-eve...
Never-the-less, I do believe it is probably a good idea for me to not sit at a computer for six hours at a stretch. But when I'm focused... I'm focused. So I've been thinking about a gadget that might help me.
And when Sparkfun showed off a new lilipad-buzzer thingy, it inspired me.
What you see above is the result of this order:
1 - $7.95 - SEN-09376 - Force Sensitive Resistor - Square
1 - $9.95 - DEV-11008 - LilyPad Vibe Board
1 - $24.95 - RTL-09876 - Lithium Polymer USB Charger and Battery
1 - $19.95 - DEV-10274 - LilyPad Arduino Simple Board
Plus some wire, a PN2222 transistor, a couple of resistors, and a bit of solder.
The stuff came yesterday and I whipped this up today, attached it between two pocket sized pieces of cardboard and sat on it.
After 20 minutes, the buzzer goes off until I stand up. If I sit down again before 2 minutes, the buzzer goes off and the count starts over. After standing for 2 minutes, the buzzer goes off briefly to let me know when its OK to sit again.
I should probably add a blink every few seconds (so you know the batter isn't dead) and explore the ATMega328p's sleep capabilities. I'm guessing that cell-phone class battery is over-kill for this application. Actually, the whole gadget could probably be made much more cheaply, but I know I couldn't have made one more quickly.
If this idea counts as intellectual property, then I'm releasing it under a Creative-Commons Share-Alike license. Code available upon request.
BTW, that battery went a week and a half on its first charge with no special power saving code, and only occasionally me remembering to turn it off once in a while.
My little Arduino-based balance bot resists as I try to knock it over.
Specs:
- Chassis: 1 x Sparkfun box
- Brains: 1 x Arduino Uno
- Motor driver: 1 x Sparkfun Ardumoto
- Motors: Sparkfun 2 x 24:1 gearmotor
- Wheels: 1 set Sparkfun 70mm
- Gyro: 1 x ADXRS613 (Sparkfun breakout) mounted at the axis of rotation
- Accelerometer: 1 x ADXL203CE (Sparkfun breakout) mounted at the axis of rotation
- Batteries: 2 x 3.7V Li-poly 850MAh (Sparkfun)
Pretty basic. Each temperature probe line has a 4.7k pull-up resistor connected between +5v and the data pin. Data pins are 4 through 10, and pin 1 is used for sending data to the LCD. The probes are capable of all operating on the same bus, but then I'd have to deal with addressing them individually, and making sure each probe was installed in the correct location. This way, as long as I know which pin it's connected to, I don't care what its serial number is.
this is my arduino powered physical progress bar prototype. This is connected to a computer via an arduino. It can be a countdown clock for your workday, it can mirror your desktop pc's progress bars, it can receive a signal from your computer indicating lag, server load, processor speed, or amount of unread emails! Lastly it can take sensor input (it is an arduino after all!) and display that. I could see that being useful to quickly show co2 levels in a greenhouse, temperature, or volume of ambient noise.
It has an arduino, a servo, and some custom laser cut acrylic gears under the hood to move the bar. It will be laser cut out of 3mm acrylic and utilize t-bolt joints to keep everything together.
It's built around an arduino: what do you want to hack it to do?
Arduino with DC Motor.
The Arduino is connected to my computer and is pre-programmed to listen to a variable sent from a Python script running in the background of my computer. The Python script connects via IMAP to my gmail account and scans for the keyword, ‘water’, in the Subject field of any new email. If it finds an email that meets the criteria, it tells the arduino to start pumping!
This project was accomplished with a micro-controller and help from NYU’s ITP website. Thanks Tom Igoe.
Also, for the email processing functions of this project, I switched from Ruby to Python. Accessing basic IMAP search functions of email accounts is easily done in Python.
