- Balsa TARDIS with Pulsing LED Light
- 21 Aug 2012 11:02:00 pm
I got a Doctor Who-themed present for my girlfriend last month, as she is also a Whovian, and to make it extra-special, I decided to whip up a custom box. I used sheets of balsa wood for the sides, bottom, and top, and used 1/8"x1/4" sticks of balsa to join the sheets at edges and corners. For good measure, I put a jumbo 7mm white/clear LED on the top as a light, but I didn't have the time to make that LED do anything. Using what I had at hand, the wood is "painted" with blue and black Sharpie markers. This weekend, however, I decided to pull out a breadboard, a 555 timer IC, and my residual recollections from my junior-year analog electronics course, and whipped up a fading circuit for my LED, powered by a 9V battery. Enjoy!
