Re: [psas-avionics] Update
It may not come as a surprise that the network works after it was working just fine before. The big deal here is that we are now using the fancy Ethernet switch to create multiple VLANs to isolate critical data paths. With multiple networks, we need something to route data between them. Thanks to the magic of tagged VLANs (802.1Q), all of these VLANs are delivered over one physical interface to the Intel NUC. So now the NUC is functioning as the core router on top of telemetry and other duties. With this change we were able to switch to a dedicated link between ground and launch tower. Hopefully that will help with some of the tower communication issues we have seen in the past. A dedicated VLAN has been created for non-critical ground WiFi so that service can easily be disabled if communication problems pop up. Most importantly with all of these different VLANs, we will be able to quickly narrow down where network issues are occurring. This should put us in a good place to spend more time squashing bugs than hunting for them. Immediate concerns: - Most off-rocket hosts have new IP addressees. Any associated hard-coded addresses will need to be updated. - Live AIS data is not displaying at the FDT. Maybe a socat command on the tm3k needs a fresh IP? Future work: - setup Nagios - setup remote syslog everywhere - install Splunk - win!

[psas-avionics] Update
Glenn, Devin and I met today to talk communications. We'll be meeting each Friday after noon for those interested in chatting about comm for rockets, balloons and satellites. After some discussion, we decided that we're sticking with 2m for ground comms for the foreseeable future. We took the Jpole out of the giant plastic tube, and that makes it smaller and easier to mount to the antenna pole. Kenny got the entire FDT/LTC/FC network stack up and running. After some stupid configuration problems with the ubiquiti POE-to-wifi adapter, it now just all works. We even power cycled it and made sure it came up sanely. Go Kenny! Next: more work on Sunday. See you then!

Hi! Mostly good news. We have everything up to final countdown down cold, with all of the SOPs updated. There's plenty to do, but hopefully by Tuesday we'll finally get through an entire launch sequence. The GPS board is now reliably putting out raw data in serial format... although DATA_SYNC and TIME_SYNC are mysteriously not working. We'll work on that on Tuesday as well. Remember, big hack day this Friday (7/4) in the morning / early afternoon to put together the last bits of the avionics system.

[psas-avionics] Update!
Hey! Things Got Done today. - TrackMaster 3000 (TM3K) has been resurrected, and is now running with the new Atheros USB Wifi adapter, updated RasPi packages and network configuration, and is powered off of POE. - LTC setup procedures were worked on, and may even be right. - We have the FC command path working: Laptop -> OpenWRT -> LTC -> Ethernet over Umbilical cable -> FC - We have the telemetry path working: FC -> WiFi -> TM3K -> Raspi -> OpenWRT -> Laptop - And we even got the first serial ADC data bits out of the GPS board. There's still a lot to do here, but at least we know we're barking up the right tree.

[psas-avionics] Update from today's hack day, probably one on Sunday?
Hi everyone, Lots of cool stuff today: - Theo and John got the LTC to work!!11!! Using their awesomely touch-y Kivi UI, you can now log into the LTC and flick relays, see voltages, and even launch a rocket. Although it of course needs a LOT of testing, this means we're officially ready to go with the new LTC for flight. (PS Theo and John: I ordered the Phidget sensor). - Kenny got the BeagleBoard updated so it doesn't corrupt the file system if you turn it off. Yay, Kenny! Kenny also is attempting to get us a donated Atom board for the LTC, which would be awesome - cross compiling and building an image for the Beagle is a bit of a pain. - The Rocketnet Hub is 99% ready for fab. I'd send it today if I had to, but since it won't start fab until Monday morning, I'll take the weekend to get that pesky 1%. Despite the fact that it's Father's day, I think we'll do another hack day this Sunday from noon until evening at PSU in 84 Lab. If you can't get in the EB on the weekend, just call my cell, 503-708-7711 and we'll come up and let you in.

[psas-avionics] Update from today
Hey, let's try that again! Glenn, Jamey, K and I played around with the CPAs in the PSU emag lab: http://psas.pdx.edu/news/2011-08-19/ Conclusion: we're good to go on the WiFi antenna, and we're going to try to "Xacto-tune" the GPS and ATV antennas, probably next Friday. We also worked on the FC back at the PSBA afterwards, and the FC now talks to the new 7 port hub. We tried a USB flash drive and the WiFi adapter, and everything seemed very stable. We didn't manage to set up a WiFi network despite Josh's help, so we'll try that Tuesday. Next on the agenda: fix The GPS, and 5 GFEs, one of which will go on the rocket. Oh, and solder up the IMU PCBs - looks like we're not getting a sample of Analog Device's ADIS16407 IMU. :) Andrew -- --- Andrew Greenberg Portland State Aerospace Society (http://psas.pdx.edu/) and...@psas.pdx.edu P: 503.788.1343 C: 503.708.7711 --- ___ psas-avionics mailing list psas-avionics@lists.psas.pdx.edu http://lists.psas.pdx.edu/mailman/listinfo/psas-avionics

Re: [psas-avionics] Update
Yeah, I have also noticed those dummy loads don't seem to broadcast very well...

[psas-avionics] Update on CPAs
Hey everyone, Just talked with Dave at Parks PCB. They're willing to do another antenna run for us. Yay! And it looks like they may be able to accommodate our slightly larger antennas, too, although it'll be close. We're currently checking into 0.005" PCB material availability - we may need to do a minimum order, which might be expensive. In the mean time, we need a sanity check and design review on Tuesday, at which point we'll generate us some Gerbers.
