Introduction: Sonic ScrewDriver TVBG
I'm a big DW fan. Probably not big enough to build a tardis in my room, but close. Big enough to buy a toy sonic screwdriver off amazon in 2007. Sadly it's cool noises and UV light only kept me amused for 3 to 4 weeks. So, I set about figuring out how I could make it more fun. Around the same time I ran into the inventor of the TVBG in San Francisco, and the result you can see. Took me freak'en forever though. Because I didn't know anything about electronics, AT ALL. I had heard of electricity and knew that made the lights go in the house.
The one draw back with this Sonic Screwdriver is there is no sonic. The original board in the toy has been rolling around my project box for a while and was subjected to two transatlantic flights, a winter in Boston (understandably, I barely survied that trip), travel to the Bay area and then to Oregon. It stopped working. Otherwise I would have wired it in parallel. But at some point this heavy addiction starts taking a toll on your loved ones and you decide it's time to finish it. I know there are at least two others out there who had the same idea as me (there is no such thing as a original idea). You know who you are. So, there is room for improvement, like a super bright blue LED instead of the green one and the wide angle IR. Smaller IR LED's is a good idea as well, less effort to squeeze it into the head.
I did use a pre-programmed chip and components from Cornfield electronics just because red hair dye doesn't come cheap and Mitch needs to stay on the cutting edge o'fashion .
I also used the $3.50 mini tvBG intructable as a guild. Which helped a lot. And there is little reason to try and re-write an excellent instrutable.
here is a video for it working. I added all the sound effects post production http://youtu.be/AhgCIdJ8kPQ
