+Over the weekend, I put two more
+[TeleMetrum](http://altusmetrum.org/TeleMetrum)
+boards together, serial numbers 7 and 8. The good news is that both boards
+turned on and worked right the first time, but only after working around what
+appears to be an icky bug in the kernel cdc_acm driver. We've seen various
+problems with this driver before, but for some reason my ability to talk to
+our programming dongle failed hard this weekend. In the process of digging
+around for helpful info online, we discovered that the usbserial driver can
+be made to work with our boards, and are pondering switching. More on that
+later.
+
+Building these two boards used up the last of my cache
+of the expensive parts, and we'd like a few more boards for upcoming launch
+events like [Chili Blaster](http://www.scronline.net/html/chili_blaster.html)
+and [NCR Oktoberfest](http://ncrocketry.org/modules.php?name=Oktoberfest), so
+I ordered more parts... and as of this morning they've started arriving. The
+plan is to build up another half-dozen full TeleMetrum boards, and two
+partially-loaded boards for use in our first
+[TeleTerra](http://altusmetrum.org/TeleTerra)
+prototypes.
+
+A special note for folks near Colorado. Weather permitting, on Sunday morning
+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
+Chamberlin's similarly-sized [Polecat Fat Man](http://stores.whatsuphobby.com/-strse-11/Polecat-Aerospace-10"-Fatman/Detail.bok) on long-burning
+[Aerotech](http://www.aerotech-rocketry.com/)
+[M650W](http://www.thrustcurve.org/motorsearch.jsp?id=471) motors
+at [Chili Blaster](http://www.scronline.net/html/chili_blaster.html). Even
+for those of us who fly high power model rockets every chance we get, a
+drag-race between 10-inch airframes on long-burning M motors is a special
+event. If you've never seen rockets like this fly, and/or would like to see
+a TeleMetrum board in action, that could be a great day to come hang out
+with us!
