I’ve been a bit quiet recently. My last post was about controlling some lights with a sonic screwdriver with a Raspberry Pi handling everything. I’ve been expanding on it (which I will go into great detail in a later post) and one of the greatest tools I’ve found has been transistors. I’ve used them in the past but I’ve never really known what they actually do. It’s kind of embarassing because it’s so simple. In layman’s terms (and possibly the wrong description), a transistor is a sort of switch.
One thing that really annoyed me about the lights in my room is when I went to bed I would always forget to turn the lights off and have to climb out of bed and turn them off. That sounds like a first world problem, and well it is. But I had a solution in mind. Back a few years ago I would control my lights with one of those cheap remote outlets you would find at places like Home Depot or Lowes around Christmas time. I took the only one I had a long time ago to see what made it tick. Before I ended up frying the remote, I discovered that it was nothing but a RF transmitting remote and receiver. The receiver would get the signal from the remote and flip a relay.
Recently I built myself a nice media center. I obtained a 16×3.5″ bay IBM server case. It’s 4U tall and really makes one hell of a system. This case is very, very big so I probably shouldn’t be using it as a media center case but what’s technology if you don’t over do it here and there.
So as promised in my MAME machine build log submitted the day before this post, I have a pretty big announcement. Today I picked up my first pinball machine, a Gottlieb Super Mario Bros.
