The 6th day of holiday...hmph...still haunted by the upcoming exam. Yes, Microbiology final exam. The exam is due on January 5th...but I haven't studied anything...just printed out some chapters (yet to be read). I need to make something in order to bring my energy back (thus bring the energy to study)!!!
At first I planned to make a customized music box. I started up by buying a cheap music box to understand the mechanism. I unscrewed the parts, and saw electrical circuit instead of mechanical movement (which I expected). Then I realized they don't sell any mechanical music box in this country. Great. But the mechanical ones are harder to customize than the electronic ones, anyway. So then new idea sparked on my little grey cells to make an electronic music box. I have the PCB image in my head. But the board is just for one note, not the full tune. With my limited mind on electronic matters (I'm an idiot on this) I'd end up with board after board connected by tentacle-like wires to produce 26-notes tune. Why? The mental circuit board is without any IC, so basically a circuit is just for one note. I thought, "I can change the frequency of a tune by adding a different resistor into each circuit. So a tune needs one resistor." Imagine the space needed. Then I came across a shortcut idea. I'd use a recording IC, so it can be connected to play and stop bottom and just done! Great was my joy when I discovered such IC actually exists. I wanted to buy it instantly, but unfortunately it's too pricey (also there's no guarantee that I'd succeed. Most likely I'd screw everything). Until now the project is still pending...
I need magic!
