So for our first fabrication class we were asked to make a flashlight, whatever we considered that to be. And I had no idea how to do such a thing. The only things I remember from high school engineering are making technical drawings and a pretty nice roller coaster for marbles.
I at least knew I wanted to stay small and stick with a paper construction for housing – so that meant using some appropriately small lights and batteries (because actual flames would be a no go). Playing with an LED and some coin cells, I can admit that just getting it to light up was an incredibly satisfying moment.
Wanting to also be able to turn it off and on, I was tempted to macgyver a switch by sticking a tab between two batteries and hoping that would work out (it does!), but apparently battery holders are inexpensive and much more likely to reliably function. Solder is also more reliable than tape; that was also a good lesson. So Spot-light was built a tiny body measured to support his insides, and with an accessible back so that I can go in and fix him up later.
I’m sure there should probably be a resistor in there somewhere? And some of my corners aren’t quite exact. But for not knowing how to technically make a flashlight, I think Spot-light’s a pretty good dog.
