group project for Thunda in 2015?

by Bdale Garbee

Keith and I both hope to be able to attend "Thunda Down Under"[1] in 2015, and I've sent the organizers email requesting information on what it takes to be treated as an on-site vendor. Of course, it's always more fun to be at a launch when you have something interesting to fly! Thus, while Keith and I might each show up with a modest "travel rocket" of some sort... I've started pondering possible larger "Altus Metrum" group projects. Since transporting a large airframe to Australia would be a hassle, I wonder if a group project to build an airframe in-country makes more sense? To that end, I'd be pleased to know if any of our friends and customers in Australia want to sign up to help with such a project? My thoughts would be to engage in some group-think about project scope and goals, then hope friends in-country would take on the sourcing and preparation of suitable airframe materials. Depending on who wants to participate and how tasks get taken up, we might plan to arrive a bit early to help with any final assembly or other preparations, installation of suitably fresh Altus Metrum electronics, etc. So, to all our Aussie friends... does this sound like fun? If so, please chime in with a reply. I don't expect the email associated with such a project to be too heavy a load for this list to carry, but we can always spawn a dedicated lists.gag.com list if I'm wrong. Regards, Bdale [1] http://thunda.com.au/

a brief interruption in services

by Bdale Garbee

Some of you have noticed that I've been less responsive recently, in particular some orders have been slow to ship, and some repairs have sat longer on my bench than usual. My apologies for that, I hope that things will be back to normal in another week or two. That's because I'm immensely pleased to report that we slept in the new house for the first time last night! Yep, we're "home" for the first time in over 15 months. See http://gag.com/blackforestfire.html for details if you haven't heard the story somewhere yet. Altus Metrum World Headquarters is still in a leased garage unit at the apartment complex, and will be for a few more days. Thank you very much for your continued patience with me as we work through the remainder of this (happy!) transition! Bdale

Thanks Bdale, I'll definitely be twisting all the wire pairs per the manual - which I actually did read ;-) With he electronics on the one side I have room for both lipos on the other side with the switches and the bulk of the wiring. I'll post when I get it all together. - Scott On Sep 23, 2014, at 2:00 PM, altusmetrum-request(a)lists.gag.com wrote: > Send altusmetrum mailing list submissions to > altusmetrum(a)lists.gag.com > > To subscribe or unsubscribe via the World Wide Web, visit > http://lists.gag.com/mailman/listinfo/altusmetrum > or, via email, send a message with subject or body 'help' to > altusmetrum-request(a)lists.gag.com > > You can reach the person managing the list at > altusmetrum-owner(a)lists.gag.com > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of altusmetrum digest..." > > > Today's Topics: > > 1.

Any problems putting a TeleMega and an EasyMini close together?

by Scott Mcintosh

I am trying to get both on the same smallish sled. So I have two questions: 1) Do I need to worry about interference? I'm hoping I don't have to add any shielding. 2) Is there any actual alignment for the EasyMini? I want to mount it sideways to make room, and since it doesn't have an accelerometer I though it should be fine (I only as because the mounting hole template does indicate an "up", I put pictures of the layout here: https://www.flickr.com/photos/96008345@N03/sets/72157647912735571 Any advise would be greatly appreciates as I'm really excited about the products and hope to get something in the air for my L2 cert flight. Thanks, Scott

Telemetrum Issue

by Steven Saner

Hi guys: I have one of the v1.2 Telemetrums. It has flown a half dozen times and has always worked well. However, now when I apply power, instead of the 3 beeps (morse code for S), I am getting 4 beeps, a pause, and then one longer beep. After that I get the normal I or P morse code depending on mode. In idle mode it seems normal otherwise. I can communicate with it over the USB cable and change the configuration etc. Can you tell me what this means? I looked at the documentation but didn't see any listing of error codes or anything. Thanks Steve -- -------------------------------------------------------------------------- Steven Saner <steve(a)saner.net> KD0IJP Andover, Kansas USA

TeleDongal Receiver Issues

by compuvet＠aol.com

Over the weekend, I was testing RF attenuation due to metallic paint. In my testing, I found that my portable HTs were receiving the TeleGPS transmitter better than my TeleBT. Clearly the RF signal strength was great enough for the HT showing 6 s-units when the TeleBT was completely deaf. Keith, based on the previous thread, it seems like I may need to have my TeleBT calibrated too? Is there something else I should try? Thanks, Craig Sent from Windows Mail

Bdale Garbee, I have one of your older Altus, which I have not been able to get it to work with my laptop which has Windows Vista on it. Do I need to uninstall it to update it? Bill Wagner

[AD] Altus Metrum announces AltOS 1.5 with EasyMega

by keithp＠keithp.com

Altus Metrum announces AltOS 1.5 with EasyMega Our newest flight computer, EasyMega is a TeleMega without the radios: * 9 DoF IMU (3 axis accelerometer, 3 axis gyroscope, 3 axis compass). * Orientation tracking using the gyroscopes (and quaternions, which are lots of fun!) * Four fully-programmable pyro channels, in addition to the usual apogee and main channels. New features in the AltOS firmware: * The APRS secondary station identifier (SSID) is now configurable by the user. By default, it is set to the last digit of the serial number. * Continuity of the four programmable pyro channels on EasyMega and TeleMega is now indicated via the beeper. Four tones are sent out after the continuity indication for the apogee and main channels with high tones indicating continuity and low tones indicating an open circuit. * Configurable telemetry data rates. You can now select among 38400 (the previous value, and still the default), 9600 or 2400 bps. To take advantage of this, you'll need to reflash your TeleDongle or TeleBT. Bug fixes in the AltOS firmware: * TeleGPS had separate flight logs, one for each time the unit was turned on. Turning the unit on to test stuff and turning it back off would consume one of the flight log 'slots' on the board; once all of the slots were full, no further logging would take place. Now, TeleGPS appends new data to an existing single log. * Increase the maximum computed altitude from 32767m to 2147483647m. Back when TeleMetrum v1.0 was designed, we never dreamed we'd be flying to 100k' or more. Now that's surprisingly common, and so we've increased the size of the altitude data values to fit modern rocketry needs. * Continuously evaluate pyro firing condition during delay period. The previous firmware would evaluate the pyro firing requirements, and once met, would delay by the indicated amount and then fire the channel. If the conditions had changed state, the channel would still fire. Now, the conditions are continuously evaluated during the delay period and if they change state, the event is suppressed. * Allow negative values in the pyro configuration. Now you can select a negative speed to indicate a descent rate or a negative acceleration value to indicate acceleration towards the ground. New features in AltOS for Linux, Mac OSX and Windows: * Added icons for our file types, and hooked up the file manager so that AltosUI, TeleGPS and/or MicroPeak are used to view any of our data files. * Configuration support for APRS SSIDs, and telemetry data rates. You can read more about this release on the AltOS web page: http://altusmetrum.org/AltOS/ Altus Metrum products are available from our distributors Apogee Components, Bay Area Rocketry, and Chris' Rocket Supplies in the US; Australian Rocketry; Rebel Space in the Netherlands; Sierra Fox Hobbies in Italy; and Aerospace Education in New Zealand.

"* Increase the maximum computed altitude from 32767m to 2147483647m " ... Looks like the first step toward a "lunar mission qualified" product :). LunaMetrum perhaps? Too bad we need so darn much fuel to get there! Hats off to you gentlemen!
