3 Over the weekend, I put two more
4 [TeleMetrum](http://altusmetrum.org/TeleMetrum)
5 boards together, serial numbers 7 and 8. The good news is that both boards
6 turned on and worked right the first time, but only after working around what
7 appears to be an icky bug in the kernel cdc_acm driver. We've seen various
8 problems with this driver before, but for some reason my ability to talk to
9 our programming dongle failed hard this weekend. In the process of digging
10 around for helpful info online, we discovered that the usbserial driver can
11 be made to work with our boards, and are pondering switching. More on that
14 Building these two boards used up the last of my cache
15 of the expensive parts, and we'd like a few more boards for upcoming launch
16 events like [Chili Blaster](http://www.scronline.net/html/chili_blaster.html)
17 and [NCR Oktoberfest](http://ncrocketry.org/modules.php?name=Oktoberfest), so
18 I ordered more parts... and as of this morning they've started arriving. The
19 plan is to build up another half-dozen full TeleMetrum boards, and two
20 partially-loaded boards for use in our first

24 A special note for folks near Colorado. Weather permitting, on Sunday morning
25 the 23rd of August, I'm planning to "drag race" my [big Goblin](http://www.flickr.com/photos/bdale/3568189349/) airframe against my good friend Jason
26 Chamberlin's similarly-sized [Polecat Fat Man](http://stores.whatsuphobby.com/-strse-11/Polecat-Aerospace-10\"-Fatman/Detail.bok) on long-burning

28 [M650W](http://www.thrustcurve.org/motorsearch.jsp?id=471) motors
29 at [Chili Blaster](http://www.scronline.net/html/chili_blaster.html). Even
30 for those of us who fly high power model rockets every chance we get, a
31 drag-race between 10-inch airframes on long-burning M motors is a special
32 event. If you've never seen rockets like this fly, and/or would like to see
33 a TeleMetrum board in action, that could be a great day to come hang out
