CATaLOG: RFID Cat Tracking

May 27, 2009 by Caleb Kraft 21 Comments

Like many pet owners, [Pete] was curious about his little furry friend’s habits while he was gone. He decided to build an RFID tracking system to monitor their positions. This data would then be available on the web. An Arduino handles the communication of the data, both to twitter and his personal cat tracking site. We were a bit surprised to see that the only data transmitted on the final project was whether the cat was inside or out. We’d like to see a heat map of the cat’s activity in the house.

IFob: Keyless Entry

iFOB-11-M (Custom)

[Nate] hates keys. He’s gone through a lot of effort to remove them wherever possible. He has a keypad at home and a keypad at work, but he still has to carry car keys. His solution is to build a device he can carry in his pocket that will unlock the car via RF. To do this, he’s utilizing the guts of a Nike iPod puck along with an Arduino and an iPod serial board. He has managed to get this all working, but still has to carry his key to actually start the car. We know what his next project will be.

Laser Cut Drum Kit

drums

[Segwaymonkey] picked up an arduino based drumkit circuit and needed a kit to place it on. He worked up a pretty cool design and had it laser cut out of acrylic. The cool part of the design is how he delt with the head motion of the drum. Each head has 4 “springs” that were also cut from the acrylic. The Arduino based drum circuit sits on a little pedestal in the middle, as though it were on display. We really like the design, but we have to wonder if a little noise dampening on the heads might be a good idea. He hasn’t released the plans, but says he might once he gets it perfect.

Snoozy The Sloth

Snoozy the Sloth clings to you and sleeps. While this may sound easily done, the maker wanted the sloth to actually simulate breathing with exhaled breath to add to the realism. To do this, they had to build a “respiratory system” out of a rubber glove, a solenoid, and a couple pumps. This kind of toy can be very beneficial to special needs children. The lifelike and calm behavior helps the child connect to the toy. The pumps and solenoid are said to not be too distracting, but we are curious just how loud they are. This seems well executed, and much more sloth like than slothra, another sloth toy from last week. Were these guys in an Arduino powered sloth making class together?

Peggy 2 Super Pixels

[Windell] from Evil Mad Scientist Laboratories took one of their Peggy 2 kits and gave it a little upgrade. The Peggy 2 is a programmable 25×25 LED display. It’s Arduino compatible and can accommodate big 10mm LEDs. Most people assemble them using just one color, but [Windell] decided to create giant RGB pixels by placing discrete red, green, blue, and white LEDs next to each other in the board. This creates a 12.5×12.5 grid of full color pixels. It’s an interesting effect and you should definitely check out the video embedded below which shows how the transition can be smoothed using a diffuser. Continue reading “Peggy 2 Super Pixels” →

Twittering Toilet

May 5, 2009 by Caleb Kraft 38 Comments

We wouldn’t want to let a week slip by without something new being made to twitter would we? This time it is a toilet. Don’t worry, they are sparing us the graphic details, it pretty much tweets every time it is flushed. As you can see in the picture above, they’re using an Arduino for the toilet/PC connection. If you really want to make something twitter, this might be a good starting point. It’s basically twittering every time a button is pushed. You can download the source code on the site as well as find a tutorial on Arduino basics.

Guitar Hero Macro Board

Doesn’t look like the Guitar Hero hacks will be slowing up any time soon. In this recent installment, [Thunderhammer3000] built a board to record Guitar Hero “songs”. It is wired inline with with the fret buttons and strum bar and records each of the key presses. Songs can be recorded at slow speed in practice mode and replayed at full speed. The board is Arduino compatible and has two optoisolator chips for collecting the button presses plus a small EEPROM for storage. The board fits easily inside the guitar body.
