So, quick status report before I sleep. I haven’t been getting enough sleep, so I’m kind of wiped out right now. My day went like this: school, talk to professor, eat, school, work on next iteration of coilgun, break an ott light, eat greasy food, go to a concert, made a smoothie, and tried to hack a quickie robot before realizing that I am an idiot and have no place on this earth. So.
School was fine: day on which nothing is due, which is good. Talking to a professor, I now have a smaller chance of being rejected outright by USC. Next iteration of the coilgun will have multiple stages, and we almost have it all set up, but the charging system we’re using seems to have broken over winter break. However, we got the arduino-controlled firing system working, and have a separate 328 chip on a breadboard acting as our arduino, since we fried our last one. Great fun. There were more than a few instances in which I had an LED plugged in the wrong way, so I had no idea it was working.
After we found out that we were hungry as heck and needed to eat, my fellow hacker left, and since I couldn’t figure out how the ott stand was screwing with wall power, I just plugged the bulb directly into the wall. Of course that was a bad idea, and now everyone should know that while the stand doesn’t screw with the voltage, it almost definitely tamps down the current available, probably through the inductor-looking thing. Fortunately, it did not blow up, which was my realistic worst-case scenario fear. It does have a crack in it, and who knows what’s in the lamp, so I might wake up tomorrow morning as some horribly mutated thing. If that happens, I recommend ceasing all attempts to hack such lamps; don’t worry about me, I’ll have done it FOR SCIENCE. Right.
Since that lamp is gone, I’ll probably have to mash up a system of LEDs to aleviate my current lighting situation. Maybe. LEDs can be not so great for lighting, so I guess I’ll try it and see how it turns out.
Friday cafeteria food has a theme of greasiness, which is unfortunate. I’m already pretty unhealthy, which I will have to rectify. Talked to fellow humans, and saw a pianist play some pieces I have not heard before. He was pretty good, but not quick kick-ass.
After the concert, I tried to stick together a very simple robot. It’s a differential drive, that derives obstacle avoidance through 2 dpst switches that switch the polarity of the motor when switched. It’s pretty simple in theory, and should’ve been simple in practice, but I have no working robot that can scuttle around and keep me happy. After 1.5 hours of working on that, I decided to switch to my pre-amp, but I looked at the schematics, the bottom of my perf-board, and now I’m here to tell you all that I need more solder. I’ll have to find if there’s a radioshack nearby.
Basically, nothing got done. Some groundwork got laid, but I have nothing to show. Yet. I’m not sure what I’m going to do next week. Yet.
