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 t
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 Jpol
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
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 comman
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
Hey, let's try that again!
Glenn, Jamey, K and I played around with the CPAs in the PSU emag lab:

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 F

Yeah, I have also noticed those dummy loads don't seem to broadcast very
well... They should fix that. :-)

Not bad progress tonight!
- All CPAs mounted and connectorized.
- GPS antenna seems to work (GPS locked using an LNA).
- ATV seems to broadcast beter through the antenna than a 50 ohm load :)
More testing, especially VSWR, tomorrow.

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
