Howdy, all!
The challenges of maintaining a mailing list server as the rest of the
world evolves, made particularly complicated recently by changes Google
has made to how Gmail does and does not work with list servers, finally
crossed a threshold for me, and I just don't want to do this any more!
So, effective immediately, the altusmetrum(a)lists.gag.com mailing list
should be considered defunct.
To replace it, I've created an altusmetrum list at groups.io. If you
want to continue to keep up with what's going on in the land of Altus
Metrum rocket electronics via email, please subscribe yourself to the
new list!
The new list home page is: https://groups.io/g/altusmetrum
If you prefer, I believe you can also start the subscription process by
just sending an email to: altusmetrum+subscribe(a)groups.io
If Facebook makes you happier than email, note that you can also
join the Altus Metrum Facebook group, which has 568 members as of
today. We post "press releases" in both places, but conversations may
or may not overlap: https://www.facebook.com/groups/altusmetrum
Regardless of what you decide to do or not do, thank you for your
continuing interest in Altus Metrum products!

Hello,
My name is Nathaniel and I am part of the Oregon State University USLI NASA
competition team. We recently did a full scale test launch in Brothers
Oregon. The first seconds of the flight went well up until approximately
2.86 seconds after boost. At this point in flight the drogue chute deployed
then a few seconds after the main chute. After looking at the data from the
flight computers it was noted that the pressure sensor reading was
constant. I was wondering if anyone else has had this occur with the
Telemega V5 or what could have caused this to happen? An inspection of the
pressure sensor itself was done and the sensor did not have any
obstructions in the sensor holes or faulty soldering connections. I can
also send over the flight data from the computer itself if that would be
helpful. The team also had a redundant flight computer (EasyMega) which I
can provide data for as well.
Best,
Nathaniel P Hannan

Altus Metrum announces TeleMega v6.0, TeleMetrum v4.0 and AltOS 1.9.15
Announcing TeleMega v6.0
TeleMega is back in stock! We're pleased to announce the next version
of our top of the line flight computer, TeleMega. Version 6.0 is
feature and performance compatible with version 5.0, using a new
6-axis IMU but otherwise using similar components as version 5.0.
TeleMega is an advanced flight computer with 9-axis IMU, 6 pyro
channels, uBlox Max 8Q GPS and 40mW telemetry system. We designed
TeleMega to be the ideal flight computer for sustainers and other
complex projects. Read more about TeleMega here:

Announcing TeleMetrum v4.0
TeleMetrum is back in stock! We're pleased to announce the next
version of our TeleMetrum flight computer. Version 4.0 is feature
compatible with version 3.0, incorporating a new Atmel microcontroller
but otherwise using similar components as version 3.0.
TeleMetrum is a dual-deploy flight computer with built-in GPS tracking
and telemetry. Read more about TeleMetrum here:

Announcing Altos 1.9.15
This release contains support for TeleMega v6.0 and TeleMetrum v4.0.
AltOS changes:
* Add support for TeleMega v6.0
* Add support for TeleMetrum v4.0
Read more about AltOS here:
https://altusmetrum.org/AltOS/
Altus Metrum announces AltOS version 1.9.14
This release contains only a fix for TeleLCO; the previous version
(1.9.13) introduced a regression that broke the scanning process for
discovering available TeleFire devices. We're making this announcement
just to let people with TeleLCO boxes know not to use 1.9.13.
AltOS Changes:
* Fix 1.9.13 regression in TeleLCO startup sequence that
detects available TeleFire units.

Altus Metrum announces AltOS version 1.9.13
This release contains a couple of important firmware changes and users
with TeleMetrum, TeleMega and EasyMotor boards are strongly encouraged
to update.
AltOS Changes:
* Add option to beep max height in feet after landing
* Fix APRS reports to be sent at the correct time and spacing.
* Fix possible barometric sensor communication failure when
the CPU is busy talking to the radio at the same time. This
would cause loss of telemetry and failure to track the state
of the rocket during flight. This was aggravated by the APRS
reports getting sent more often than they should.
* Change EasyMotor v3 code to base logging on motor pressure
rather than the accelerometer. This allows use of EasyMotor
v3 in a static test stand, and allows EasyMotor to be
mounted in any orientation in an airframe.
AltosUI Changes:
* Add support for configuring the units used to report height
after landing on the beeper.

Altus Metrum announces EasyMini v3.0, EasyMotor v3, and AltOS 1.9.12
Announcing EasyMini v3.0
EasyMini is back in stock! We've managed to find parts for a slightly
redesigned EasyMini. This version works just like the older verisons
and it's still priced at only $80. EasyMini is a two-channel flight
computer with built-in data logging and USB data download. Like our
more advanced flight computers, EasyMini is loaded with sophisticated
electronics and firmware, designed to be simple to use yet capable
enough for high performance airframes. Perfect as a first flight
computer, EasyMini is also great as a backup deployment controller in
complex projects. Learn more about EasyMini at:
https://altusmetrum.org/EasyMini/
Announcing EasyMotor v3
Find out how well your latest research propellant actually works under
flight conditions! EasyMotor is the first motor characterization product
from Altus Metrum. A stand-alone board, EasyMotor logs data in flight
from a motor chamber pressure sensor and on-board accelerometer, enabling
motor performance analysis after flight. Learn more about EasyMotor at:
https://altusmetrum.org/EasyMotor/
Announcing AltOS 1.9.12
Altos 1.9.12
AltOS Changes:
* Support EasyMini v3.0 and EasyMotor v3.
* Fix TeleMetrum v2.0 config saving.
AltosUI Changes:
* Add EasyMotor log handling.
Windows Installer Changes:
* Sign Windows installer files to make Windows happy with them.

Hi Bdale/Altus mailing list folks,
I'm planning to do a two stage test on the weekend with an EasyTimer
handling the sustainer ignition with tilt inhibit enabled. My test logic
(at least how I understand it) is as follows.
Height Above Pad greater than 300m
Angle from vertical less than 20 degrees
Don't light until 5 seconds after launch
Do not fire after 6 seconds have elapsed in the flight.
Does this make sense to y'all? I'm going to be flying with an ematch in the
sustainer, not a motor, as this is a test. Hence me not being worried about
my relatively low Height Above Pad value.
Here's the config I've applied.

Any advice would be appreciated.
Kind regards,

just installed the new version on a brand new Macbook with the M1 chip. It appears to run and download data, but I have no way (or don’t know how) to say where it will be stored. The program made an Altus Metrum folder in my user account, not even in the Documents folder, which is not where I want the stuff to go. After I moved that folder and when I try to export or open and look at data I can’t navigate to where I put the files. Thoughts or suggestions?
I haven’t tried monitoring a flight yet, but is there a separate TeleGPS app? If there is, I can’t find it. I copied the one I had from the old computer and running it, the program says “No AltOS library in “/Applications/TeleGPS.app/Contents/Resources/Java”.” But then it starts but doesn’t look to do anything. On the hardware side, will I need to update the TeleGPS transmitters? It says it is running version 1.9.7.
thanks,
Charlie
