It is with incredible pride (and about equal parts shock and bewilderment) that I report that Socialbomb is the winner of NYU Stern’s Business Plan Competition! Out of the initial 155 teams that entered, Adam Simon, Scott Varland, Mihir Dange and I took on the last three on April 25 at the competition finals [...]
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.

So this week has been the week of logger-fixing, with me trying to shrink the footprint of my previous logger while getting better data from the one I’ve been using. Most of the decision (actually, all) to move loggers has been based on the need to adjust what I’ve been doing to fit the [...]
Thanks in no small part to the excellent write-up from my friend and Socialbomb compatriot Adam Simon, I’ve shipped my first round of boards out to Advanced Circuits for printing. The thesis marches on!
The boards for the personal unit are both done — microphone circuit on top, Arduino on bottom — and should be [...]
I’m writing up all my thesis garbage right now, so I’ll have to explain my love of all this at a later date, but for now I wanted to post a bit about some of my favorite projects that really put data in the hands of anyone curious about it:
Cambridge Mobile Urban Sensing (CamMobSens)
and [...]
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 [...]
Mic experimenting has been interesting, and by interesting I mean a lot of me cursing at circuitry. I’ve been tinkering with a few options, trying to find a light-weight circuit suitable for use in a tiny portable device. Finally, I have a circuit that’s working well for me, and it’s more or less this:
(Thank you [...]
The past few days have been spent hunkered over a table in the pComp lab, trying to find a way to get the simple sound monitor prototype up and running — and I think I’m finally there. Or, at least, I’ve got a start. I’ve ordered some new parts, which I have to [...]

…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 [...]
