In January Perlick challenged me to make my New Year's resolution doing something structured, as I'm generally very improvisational by nature. Now, I'm a pretty good musician, but I have a poor sense of rhythm, which I find frustrating, so I figured that would be a good thing to work at.

After failing to get Jess to buy Rock Band for the house, I decided to get a metronome and use that. Caitlin couldn't find hers, so I decided an excellent thing to do would be to build one. Naturally, in an Altoids box, as anything that could fit inside an Altoids box is always cooler when one has done so. So one 555 chip and a few hours in the basement later, I'm happy to announce success. A relaxing alternative to thesing.


I'm pretty pleased with it; I've been playing a lot of piano and guitar with it the last day or two and it works well. It's pleasantly simple to build: a pair of caps, a resistor, a pot, a speaker, a 555 and a battery are pretty much all you need, although another LED+resistor or two is nice. No need for an amp: a 9V battery gives sufficent volume through the 555.


Look, it looks like everything else built in an Altoids box! Note on/off switch and pot sticking out.




Ain't it cuddly in there? I really should put that LED someplace better. Maybe in my free time.

Thanks to Caitlin for her help in solderin' and buildin' and all.

I really should get around to writing this up on Instructables so that Christy doesn't tell me off here, but I always forget to document as I'm going along. Ah well, maybe I'll go and recreate at some point over spring break.

As you are trying to build structure, I'm trying to resist it and accept the fact that I need to do a presentation tomorrow in Teaching College Anth where I just improvise and deal with whatever the mock students (my peers) throw at me tomorrow. This is such a hard thing to do for a "type A" like myself.

Caitlin can sodder? You tellz her I iz impressed!

Put it up as a slideshow - they're specifically designed for people who were lame didn't manage to document along the way.

The finished product and layout diagrams will be sufficient for pictures, and you can do a couple of paragraphs of write-up about the why and wherefor.

I do appreciate that my predictability. It's like you read my mind.

Dave and I are thinking of building one (so we can be just like you guys, and also because there are not enough opportunities for building crap in my life). If we do, we'll take pics to better enable instructability.

<< I'm a pretty good musician, but I have a poor sense of rhythm >>

Until now, I had never heard of anyone like that, besides myself.

Cool!

And my second reaction was, "Why do Brits draw capacitors that way?" Hey, you get points for using squiggly-resistor instead of long-rectangle-resistor!
