Lady Ada’s new DIY Singing Pencil Kit!
Lady Ada, crazy-lady-hacker I met at Maker Faire 2007, has made a new fun kit that consists of a pencil that will “sing” when you draw stuff.
Our friends at Adafruit have released a fun new kit called the “Drawdio” — adapted from the original Drawdio design by Jay Silver – which lets you create a pencil that makes noisy almost-music via the variations in the resistance of graphite pencil lead. It’s $20 plus shipping. I just ordered one so I can recreate my middle school notebook sketches to literally hear the music of the anime spheres.

DIY - How to Make a Self-Ventilating Cat Litterbox!

You know that cat’s litterbox can become potentially dangerous to your health with its deadly fumes, especially for pregnant women. Now, here’s a cool way to make a self-ventilating cat litterbox so you don’t have to worry about all that invisible bad-for-your-health fumes.
I recently saw a post on Apartment Therapy showing a homemade “Cat Jet” ventilation solution (http://www.apartmenttherapy.com/ny/at-email/tools-for-pet-living-the-cat-jet-and-the-roomba-email-from-9108-062199) using a bathroom fan to vent the noxious fumes of a litter box from the inside of the house to the outside. As a home automation geek I immediately was inspired to take it up a notch by combining similar hardware to a series of timers.
Behold: Alan’s Automated Cat Jet! Total Cost? $80.
Consisting of one bathroom fan, one bathroom vent kit, one Smarthome Appliance module, and my home automation system, Alan’s Automated Cat Jet shows once again that with technology, anything is possible.
