Hereby resolve

For the dojo we’re supposed to come up with a list of ten goals for 2009 — not exclusively martial arts goals, but goals of any and all kinds. I view these as not quite the same as resolutions, or rather as a particular type of resolution. These are not things we’re going to try [...]

How much can I blog on in one day?

On closer inspection I think the filter is working more or less OK, and part of the problem was just that it was filtering a lot of what I was listening for. I yanked the RC network to in essence filter at infinite frequency and the output level went up. Still not all that loud, [...]

More board

I’ve now breadboarded a full voice of the WSG (3 oscillators) as well as the filter. Not everything behaves quite the way I expected… but it’s all right, I guess, except that the output is very very quiet — nearly inaudible. It’s better if I increase the value of R10 (a lot). Odd. It’s [...]

Random link propagation

Some pretty serious boopage here. And it glows in the dark!

Breadboarding

Not all our furniture cost big bucks. Wednesday morning I stopped at Syracuse University Excess Property and picked up a 30″x45″ Steelcase work table for $5. Managed to get it home — it barely fit in the car — and left it in the yard under a tarp until today, when I cleared a space [...]

Bwoooopapapapapap

Some years ago I started to build an ASM-1 synth, but for some reason that project stalled.
The Gakken SX-150 has put the building bug back in me, at least for the moment. I’ve ordered components for something less ambitious this time, a Weird Sound Generator. No PC board yet, I’ll start by breadboarding it.
It’d be [...]

Booop

(Edit: Link added)
Kenny thinks the SX-150 is pretty fun. And he recently saw the first three Star Wars movies, so discovering he could make noises like R2D2 brought a pretty big grin to his face.
He’s right, it is fun. Way limited (considerably more so than the Gnome) but in some ways less so than a [...]

Need for knobs (edited)

There’s a Japanese magazine called “Otona no Kagaku” (meaning, so I understand, “Science for Adults”) which apparently comes, often or always, with some cool stuff.  Volume 17 came with a kit for a mini theremin, for instance; and a special issue came with an analog synthesizer kit. I noted the latter with interest when I [...]
