Forget about machines that can replicate themselves, what we want is a machine capable of making an 8 inch wide hollow torus out of sugar. The CandyFab project has been around for a while, but with the release of the new machine, the CandyFab 6000 they are reinventing the project. Built from the ground up to be a candy constructing beast, the CandyFab 6000 might be a little smaller than the previous version, but it’s much better designed. You can get more details on the new wiki site.
[Marc] submitted this project he’s been building. It’s a web enabled HVAC monitoring system. He’s using a pic-web development board with a custom I/O daughter board to control the HVAC system. The project allows for the system to be monitored and controlled via the web. It should be able to interface with most commercial and residential systems. As usual, schematics and source files are available on his site.
[Bryan] sent in this cool doorbell he made out of an antique phone. After seeing similar phones for $150 to $399, he picked one up on ebay for $10. After some cleaning and polishing, it was looking fantastic, but fairly useless. At this point, he broke it open and started hacking to turn it into a wireless doorbell. He picked up a cheap wireless doorbell and proceeded to gut it. The transmitter side got an aesthetic overhaul, a big fancy button and nice LED in a 50’s style were added. The receiver side got hacked up as well. It was incapable of pushing the required voltage to ring the phone’s bell, so he had to do some searching for a better circuit. Since his knowledge of electronics was limited, he was looking for something that could be plugged in and work without much modification. Eventually, he found the Silvercom AG1170-s5. At $7, he swiped it up quick. It may be a bit of overkill, but he’s using an arduino to trigger the whole thing when it receives the signal. You can download the Arduino sketch on the site.
When we ran the story about the office chair that twittered your flatulent activity, many people commented on the fact that it had no method of determining intensity. Well, here’s the solution to that problem(is this really a problem?). These students built a fart intensity detector for their final project in ece 476. It measures the sound and temperature, as well as the composition of each fart. They really added some bells and whistles on this project. Not only will it display your statistics on and LCD screen after a reading, it will beep and, if your fart was intense enough, blow it away with a little fan. You even have the option of playing back the audio recording of your most recent glory.
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.

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.

[William] sent in this project where he’s using his iPhone to control his TV lift. He’s made a custom PCB with a pic18f122 microprocessor to communicate with the lift. He says it connects to the lift controls via a serial port. You can see a video of it in action after the break. We really think the shadow turning into an arrow is cool. That was a lucky accident.
