The phone application, InsaneRockets, records video, captures data, and helps with tracking down landing location when installed in a high powered (G and higher motor) hobby rocket. Warning: Launching rockets with a phone onboard is risky and a mishap could destroy the phone! When I started writing the phone application, it was not my intention to make a publicly available version. However, in the past year I have continued to enhance and add features for my personal use. Then, I noticed I could create a feature rich application for everyone to use and benefit from. I hope you enjoy using this application, quite a bit of late night hours have been put into its construction.
Prior to launching, if using your phone to assist in recovery with GPS, confirm your phone has a GPS - telemetry GPS derived by wifi will not operate in the field. Limitations may vary depending on the android device you have. These may include: Max Gs reported, inclusion of Barometer data, speed of instrument updates, and resolution of video/audio data.
Gs: The values of older phones typically are maxed on each axis at 2Gs. Known +/- Maxes: Nexus 5x:8Gs, Galaxy S:2Gs, Moto G:2Gs, Nexus 1:2Gs, Nexus S:2Gs, Nexus 4:4Gs, Nexus 5:2Gs, Nexus 6:2Gs, Nexus 6p:8Gs, Galaxy s7: >5.2Gs, Galaxy Grand Prime: 4Gs
High Battery Consumption & More: Some phones consume much more battery and run hotter than others such as the Nexus 4. It is recommended to at least review this section and then test to see how fast your phone battery drains over the span of an hour with Insane Rockets running. That way, on launch day, you are not in for any surprises. If you are worried your phone could overheat or your battery is draining fast, use these steps to reduce battery consumption:
Do not turn on battery saver: While it sounds great in theory, it disables the functionality of our App. Settings > Battery > Battery saver should be OFF, with Turn on automatically OFF as well. This option typically disables network traffic, it can disable gps type data as well.
Turn off BlueTooth: Searching for your devices at home and in your car wastes your battery and generates heat.
Turn off Auto-update Apps over cell network: Open Play Store > Settings > Auto-update apps and either turn off or set to Auto-update apps over Wi-Fi only.
Turn off Sync: Recommended for very power hungry phones like the Nexus 4: Open Settings > Accounts > Your Account Name > Then tap your account. Turning these off will stop unexpected transfers from occuring on launch day. You can turn them back on after recovery.
Turn off Wi-Fi: This is really only necessary if you have cell service. Important - Make sure you go into Settings > Wi-Fi > Advanced and turn off Scanning always available, Network Notification for public networks and THEN turn off Wi-Fi. If this is not done, Wi-Fi is not really off.
Reduce abrupt bumps on phone: Every time a bump occurs, a launch event could be triggered. While Insane Rockets will detect this as a false launch, CPU is consumed to capture video, audio, and data prior to realization of the false launch.
Endurance Tests: The Nexus 5 should last over 7 hours with these optimizations. The Nexus 4 should last 4 hours with these optimizations.
Follow guide for registration and recovery by tapping here:
Prepare you rocket for launch. As one of the last steps, start InsaneRockets and install the phone into your rocket's electronic's bay.
From another phone, login to https://www.insanerocketry.com tap the Data button and navigate to your live rocket's map page. It should look something like this:
Verify that the time is updating, that means the InsaneRockets is running. If the phone is horizontal, updates will occur once every few minutes. If the phone is vertical, updates will occur every few seconds.
Android: It is normal for the screen to turn off. This conserves the battery and makes it less likely for a mishap. You can immediately turn the screen off by tapping the power button quickly - Don't accidently tell your phone to power off!
Keep a close eye on battery life and record prelaunch by following instructions in Recovery Help.
Launch & recover your rocket!
Successful launch video footage will be in your photo album, where you take pictures and videos.
Telemetry data is available by clicking the Data button on the main page and then selecting a file prefixed with the word launch.
Testing: Simply shake the phone hard, while vertical and launch ready (portrait - this can be configured differently) to simulate a launch. You should see record: ON in the main screen. Once record turns back off, click the Data button and you will see two files prefixed with the word bogus. That means that the application figured out this was not an actual launch, but simply a knock of the phone. You can view both the video and the data file by tapping them.
Video Init Time: The amount of time it takes your phone hardware to start video recording. Shake your phone to test. If this time is greater than 1.5 seconds, make sure to use the REC from another phone just prior to launch. REC is explained in detail in Recovery Help.
Warning: Insure your phone has plenty of storage capacity to store launch video and data prior to each launch. Unexpected results will occur if storage runs out during a launch.
Upload on landing: In settings, you have the option to automatically upload the launch's data file to Insane Rocketry and the video to YouTube. For more information go to Settings.
