Spaceblimp-4 made it up to 103k feet and
back down in one piece!
See https://wiki.hacdc.org/index.php/HacDC_Spaceblimp_4 for details. (Spoiler: it was cool!)
Join us on the spaceblimp mailing list if you’re interested (https://hacdc.org/cgi-bin/mailman/listinfo/spaceblimp).
As we work through the photos and data, expect to see more fun stuff emerge.
The Project Byzantium Sprint 3 Topic has been chosen! We will revisit Sprint 1 in order to gather metrics and “stress test” the mesh protocol(s) at the end of this month (29th-1st).
Hit up the wiki page and/or the mailing list (byzantium[at]hacdc.org) and add info and share your thoughts.
Same motivation as the last post I made, but this time I’ve done it on the official build of the XO-1’s Fedora respin.

Also i fleshed out a couple other howtos related to the stuff I’ve been doing with the XOs.

There was some interest in running soundmodem on the OLPC XO-1s in our lending library and even though we aren’t using soundmodem for the byzantium project anymore I thought I would get it running anyways.
1.5 weeks later I have successfully gotten soundmodem to run on an XO.
Here is the wiki write up https://wiki.hacdc.org/index.php/OLPCSoundmodem
The process is more convoluted then I would like to get to that point so I’m going to make an image of the flashdrive I’m using that has everything setup already so everyone else just has to write it to their flashdrive/sdcard and don’t have to fiddle too much with it.
Right now I have to use external flash memory to get a new enough kernel since I haven’t been able to flash the newer nand images to the internal flash (confounding factors abound atm). I expect that if I can get the newest version of the nand image onto the XOs i can get soundmodem running easily.
