For Christmas this year, I got a little "Sound and Light Machine" kit, some assembly required. In fact, some soldering required - too fun!
I hadn't soldered anything since college, and fortunately my little brother got a soldering iron for Christmas (interestingly, that was from me - little did I know when I bought it that I'd have a chance to use it myself!).
Anyway, I've started putting the circuit board together - some photos below. Since I don't have a soldering iron, I haven't figured out yet how I'm going to finish it. I'm sure some of my geeky friends can hook me up.
When it's all done, it'll be a set of goggles and headphones that is supposed to "hack my brain," make me see pretty images and even help me meditate. We'll see...
I love Christmas presents that you get to put together, particularly if there's heat and electricity involved. I'll keep you posted on the progress, and once it's done, I'll let you know how the SLM brain hacking goes!
