Twittering Toilet

May 5, 2009 by 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.

Weather Monitoring

weather

This weather monitor can track pressure, temperature, and humidity and last several months on a pack of AA batteries. It has a PIC18f452 to control all the bits, as well as some fancy power management to get the most out of the batteries as possible. The screen displays the highest and lowest temperatures of the last 42 hours as well as having options to display all other sensor input, updated every minute or so. You can get the full schematic and parts list on the project site.

APRS Tracking

We really wish we had a little more information on the construction of this, but [Jeff] made this APRS tracker several years ago. APRS, or Automatic Packet Reporting System is a system where shortwave radios put out small packets of data that are uploaded to a database available via the web. This specific one is relaying GPS data so his family can see where they are located. With current phones, you might think this is antiquated, but he notes that he took this through New Mexico and was able to transmit his position even when there was zero cell phone coverage.

Robotic Sheep Shearing

This contraption was made in the late 80’s, expressly for shearing sheep. For some reason, it never really took off. We’re guessing because it takes forever and still requires a person to wrangle the sheep on to the holding rack. Having that person just shear the sheep themselves might be much quicker. We think they need to refine it a bit. It should be fast, and not require a person to load it. Maybe something like a modified version of this.

LED Buttons

For their final project in ECE 4760 at Cornell, [Christina] and [Joe] made a small single octave keyboard using LEDs as the input. They used a total of 63 LEDs to make the keys. Each key consists of 9 LEDs, with the center one acting as a sensor. When you lay your finger on it, the light reflects off of your finger and is picked up by the center LED. An ATMega 664 runs custom code to play a sound. You can find out more details about the construction as well as download the source code on the site. You can also download an example movie of it in action ( 7MB .mp4)

WTPA Bendable Sampler

Where’s the Party At is an open source bendable 8-bit sampler kit created by [Todd Bailey]. The initial design started about a year ago when he was instructing circuit benders how to transition to circuit design. He designed the kit to show how simply you could build a sampler. It demonstrates both clear analog and digital design. It’s meant to be a unique instrument though and features a lot of glitchy/quirky characteristics while being fairly reliable. You can read more about the device on his site. It has comprehensive parts and assembly manuals available and the kit is $75.

Steampunk Vibrator

[Ani Niow] built this steam powered vibrator. It has a milled stainless steel shell with a brass motor structure. The motor is a Tesla turbine made from a stack of Dremel diamond cutoff wheels. This drives an off-center weight to create the vibration. She tested it using a pressure cooker as the steam source. It worked, but became so hot it had to be held using welding gloves. It works just as well with compressed air though. You can see the device at the Femina Potens Art Gallery in San Francisco or later this month at Maker Faire.
