Thank you for the interest, Gerald. <br>
I have uploaded a circuit diagram, and will be working on explaining
what's what there<br>
BTW, I did the drawing on an XO 1, using Inkscape in Gnome. Slower
than the quad core, but works!<br>

<br>
let's ask Jerry (no pun: his website is <a href="http://askjerry.info" target="_blank">http://askjerry.info</a>) for
the frame design - he has also a nifty tractor body design there.<br>
<br>
Hey Jerry! do you have handy the blueprint of the tricycle that we
may share it with the friends here?<br>
Thanks!<div><div class="h5"><br>

<div>This is really great. And thanks for updating the wiki (sorry
about the cold, though).</div>
<div>Can you provide specifics on the hardware/frame for the
robot?</div>
<div><br>
Thanks.<br>

So far mspdebug Linux tools "work" in OLPC's XO computer
using the directions in <br>
<a href="http://processors.wiki.ti.com/index.php/OLPC_XO-1" target="_blank">http://processors.wiki.ti.com/index.php/OLPC_XO-1</a>
(major overhaul today, courtesy of a cold/flu)<br>
<br>
1) I beg mspdebug people to vet excessive heresies this
noob might have introduced in the How-To in that page. <br>
So far I am managing without -mcu - or -gdb. <br>
I actually have no idea what those are for, or if their
unavailability explains my so far failure to UART, or if
we should care... (for many things, it ain't broken...)<br>
<br>
2) Fedora packaging people: any way to package <br>
mspdebug msp430-libc msp430-binutils msp430-gcc msp430mcu
msp430-gdb ? <br>
What gets downloaded through yum channels in the XO is
very, very outdated, and conflicts (cf. mcu and libc).<br>
Please feel free to forward, as I have no access to "real"
Fedora people - don't even know where to look for them
without making a nuisance of myself and undue noise, and
certainly do not know who could maybe make a "package"(?)
usable for the XO. Will this be fixable for the next OLPC
OS?<br>
Daniel?<br>
<br>
3) Robotics, Science, Sensors OLPC, IAEP people, please,
if you could test the GCC toolchain? <br>
You do not need to have a Launchpad on hand. I am trying
to catch bugs and usability issues. Are the instructions
clear? as much as possible figuring out snags so it's
easier for kids and normal people.<br>

The brains of this "bouncy" are an MSP430 microcontroller
(a lowly g2152) controlling a L293 dual H bridge, senses
two switches. Its brawn a couple geared DC motors on 9V
PWM in an askjerry tricycle frame. Not counting shipping,
less than USD $10 total. Coded in an XO-1 all the way.
Enormous thanks to the mspgcc folks that helped me figure
things like how to use more than one switch...<br>
