of activity going on in the <st1:place w:st="on"><st1:City w:st="on">Portland</st1:City></st1:place>

enjoyed meeting everyone and seeing all the cool projects. I hope to make
it down there again the next Monday.<o:p></o:p></span></font></p>

font-family:Arial'>1) Anyone in the group have any dealings with the Roomba
vacuum robots? My charging circuit is um… not charging(???) I’ve
tried and cannot find any further technical docs on the unit. The “developer’s”
version has schematics for the controller board but says nothing about the 10
additional wires running from the power adapter board to the main controller
board. I am assuming that they don’t exist on the developer’s
version and only exist on my “much cheaper, yet totally hackable, refurbished,
purchased from amazon.com” version.<o:p></o:p></span></font></p>

font-family:Arial'>2) I really would love to find a cheap PC based oscilloscope
and/or 16 – 24 bit logic analyzer. Anyone in the group have experience
with the parallax version? <a

I’m looking for something that I can dump data in binary /
ascii / whatever and manipulate it on the PC.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>3) I really was fascinated by the demo this past Monday using
PureData. I’d never heard of it before and it sounded
fascinating. I installed it and played around for a good 2 hours and I felt
like an idiot. Is there a good guide on how to use it? I need the “PureData
for Idiots” guide. I made it through the on-line instruction manual
and following the short tutorials in the manual, couldn’t even get it to
add two numbers. Things like this make me wonder if senility isn’t
sneaking up a little early.<o:p></o:p></span></font></p>
