Advanced Circuits is absurdly fast. I placed the order halfway through Monday and the boards showed up on Wednesday morning. I haven’t tested them yet, though I see at least one obvious goof on my part, so we’ll see how they work.
Updates to follow.
I took the lil’ Soundbox around the floor with me for user testing this weekend, but prior to that I got a pretty good demo of it in use. The mic does a pretty good job of picking up different kinds ofsounds from all around the room, and the light responds accordingly.

The breadboarded monster has finally been turned into a functional prototype!
The lm386 circuit I’d mentioned a bit ago here did the trick, so I just transferred the whole thing to a breadboard and slapped an Atmega168 (bootloaded with Arduino) under it. The unit has the full mic circuit on top (with mic and warm white [...]
…and the prototyping continues. Given that I managed to scamper off to San Diego for a week and am woefully behind where my work plan says I should be, I’m spending this week in the lab —I really want to get a proper audio circuit set up.
Right now I’m working on getting some mic circuits [...]
It’s fun in my thesis that I get to assemble other people’s kits, evaluate them for usability, and then abuse the final product for my own methods.
(Note to self: find job in R&D in near future.)
I started by ordering a pile of kits from the folks at Anykits — they have outstanding prices and a [...]
I’ve been sorta-kinda testing my peak-finding code in Processing (in Eclipse), which serves as the basis of my thesis idea: that detecting the sounds that cross the pre-set threshold and causing a change in the color of an object will be useful in personal and public health and life monitoring.
(That’s the short, simplified, mostly garbage [...]
