Step 7The Blitzer
Now we come to a real beast!
To build this bot is rather dangerous! I REALLY mean that! It is because I used a photo flash light from a used one way photo camera. These devices use very high voltages and they can KILL you if you put your fingers onto the wrong parts.
I had to modify the flash to make it smaller so that it fits into the pumpkin. You can see on the images that I cut it in half and made a cube out of the two parts.
I wanted to make the pumpkin turn around and have some flashes then. I decided to use a small motor that I ripped out of an old CD-ROM drive. The gear was still there. That make the outer gearwheel turn rather slowly. I glued the casing of a presenter pen onto the wheel. Inside this casing I put some switches and the 3V lithium battery that powers the flash.
I wanted the flashes to appear automatically. I added a small slider switch that I ... once again ... got from an old CD-ROM drive. Those CD-ROM drives are really valuable crap ... ;-)
This switch slides along a screw and shortens, while doing so the flash happens.
I needed a power switch because the battery was meant to disappear into the casing.
All wires soldered, flash into the pumpkin, pumpkin onto the top, ignition switched on ... and ... motor started. Se the video to find out how it works ... ;-)
