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/

TeleSubmarine!

by sebastien_lec

Hi, I have a telemega who ditched into the only river in our launch area... Murphy law. We found the rocket only the following day. I am still waiting for it to dry completely before testing but I am wondering if other peoples ditched telemetrum/telemega into water. What repair did you do (if possible at all) to make it back to operational status. I expect the need to replace the barometer IC but anything else? Thank for any help/story/advice Sébastien Leclerc

DIY TeleMega

by Jared Szechy

I just sent off to have some TeleMega PCBs and masks made and was planning on building a few of these boards myself. I was curious if others have assembled these by hand and what their experience was like doing so. What reflow methods have you used (air, oven, hotplate, etc)? Thanks, Jared

Re: [altusmetrum] TeleSubmarine!

by danno

I have a TeleGPS that still appears to work OK after spending a night underwater. It doesn't have the barometric components, though. That same flight had a Featherweight Raven which got the same treatment, and still seems accurate as an altimeter. All I did with them was put them in tupperware containers with dry rice for a day or so, and give them new batteries.

Flight forensics?

by Chris Attebery

I made an L3 attempt today but it ended with an early deployment. I had a Telemetrum V2 and an RRC2+ onboard. I had a video camera with a shroud in the bay with the electronics. I'm pretty sure that it caused some sort of barametric disturbance and caused one of the altimeters to deploy its main charge. I don't really care which one, but I'd like to see if the data supports this. Can any of you take a look at my flight data file and tell me what you think? Thanks, Chris

[AD] Altus Metrum reduces MicroPeak to $30 and releases AltOS 1.6.3

by keithp＠keithp.com

Altus Metrum reduces MicroPeak to $30 and releases AltOS 1.6.3 Altus Metrum announces a new lower price for MicroPeak: $30 http://shop.gag.com/altimeters/micropeak.html MicroPeak is a tiny recording altimeter and is approved for use in NAR contests. http://altusmetrum.org/MicroPeak AltOS version 1.6.3 adds idle mode to AltosDroid and has bug fixes for our host software on desktops, laptops an android devices along with BlueTooth support for Windows. AltOS fixes: * Fix hardware flow control on TeleBT v3.0. RTS/CTS is wired backwards on this board, switch from using the hardware to driving these pins with software. AltosUI and TeleGPS Applications AltosUI and TeleGPS New Features: * Add BlueTooth support for Windows operating system. This supports connections to TeleBT over BlueTooth rather than just USB. AltosUI and TeleGPS Fixes: * Change Java detection and install on Windows. Detection is now done by looking for the 'javaw.exe' program, and installation by opening a browser on the java.com web site. * Delay polling while the Fire Igniters is visible to allow for TeleMega to report back complete status over the radio. * Disallow changing RF calibration numbers in the configuration UI. There's no good reason to change this from the field, and recovering is really hard if you haven't written down the right number. * Fix USB device discovery on Mac OS X El Capitan. This makes the connected Altus Metrum USB devices appear again. * Fix acceleration data presented in MonitorIdle mode for TeleMetrum v2.0 flight computers. AltosDroid AltosDroid new features: * Monitor Idle mode. Check state of flight computer while in idle mode over the radio link * Fire Igniters. Remotely fire igniters for recovery system ground tests. * Remote reboot. Cause the flight computer to reboot over the radio link. This provides a method for switching the flight computer from idle to flight mode without needing to reach the power switch. * Configurable frequency menu. Change the set of available frequencies and provide more descriptive names. AltosDroid bug fixes: * Don't set target location if GPS hasn't locked yet. * Fix saving target states so they can be reloaded when the application restarts. When the application is shut down and restarted, all previous target state information will be restored (including GPS position if available). * Fix crash on some Android devices for offline maps when changing the map scale or location. * Don't require USB OTG support. This kept the latest AltosDroid from being offered on devices without USB device support, although it can work without that just fine using BlueTooth. * Don't require bluetooth to be enabled. This allows the application to operate with USB devices or just show old data without turning on the bluetooth radio. * Recover old tracker positions when restarting application. This finally allows you to safely stop and restart the application without losing the last known location of any tracker.

TeleGPS version 1.6.3

by Tim Cubbedge

When my TeleGPS is connected to laptop, I am unable to connect to the device under "Monitor" menu. In other words, when it asks to select device, no devices show up in that window. On the other hand, when I use the "Device" menu and try to configure my device, it will list my TeleGPS and allow me to configure it. I am using WIN10. I have reloaded software. Any thoughts why device does not show up in Monitor when tying to connect device? Thanks! Tim

USB VID

by Jared Szechy

I noticed that all the devices use a USB VID of 0xfffe. I'm going to guess this has not been registered with USB-IF, since their highest issued VID is 0x2700. Have you thought about registering with USB-IF or using pid.codes <http://pid.codes/howto/> or openmoko <http://wiki.openmoko.org/wiki/USB_Product_IDs>? It also looks like ST unofficially sublicense's PIDs: https://my.st.com/public/STe2ecommunities/mcu/Lists/cortex_mx_stm32/Flat.as… https://github.com/micropython/micropython/issues/47
