Nice! I've got a decent pile to burn: 5 J's, 2 K's, and 1 L. Now I'm hoping for good weather....

I’ve got the gyro code you need posted to my page on GitHub. PM me if you are interested and I can help you make it work https://github.com/SparkyVT/HPR-Rocket-Flight-Computer

Boron? I'm curious if you are thinking of another way to make a green flame. My understanding is that you need a green-light producing compound since green is a primary color on the light wheel. This means that if you try to add Blue (Copper) and Yellow (Sodium) you'll get white instead of...

Thanks. I sent them an email but haven't heard back yet. I'm using low-current e-matches so hopefully brownout won't be an issue.

The manual says the recommended operational range of the RRC2+ is 40,000ft MSL, but it is 100,000ft capable. We are planning to fly to about 43,000ft MSL. Can anyone confirm that the RRC2+ will still operate apogee ejection charges above 40,000ft MSL? Or is it like the old MAWD that fired...

Snap-ring motors are different. I personally do not recommend leaving the snap-rings inserted for more than a few hours or a day. The rings will lose thier springiness and relax over time. I left some snap-rings in a 75mm motor for about 2-3 months and was shocked when I compared it later to...

No problem. It's all on the site. I'm constantly updating the code and will post some improvements in the next week or so. The latest version will make the tilt-inhibiting 2-stage ignition code much more portable. I'm also working on some LoRa libraries that will make telemetry at Spaceport...

This one basically is a TeleMega without the smartphone app. IMU, High-G Accelerometer, GPS, high-rate data recording, live telemetry, 4 pyro outputs, tilt-inhibiting 2-stage ignition, ability to directly drive 4 servos, audible beeper, magnetic arming switch. The smaller board is for the...

Can you send a screenshot of the voltage dropouts? I cant read that file. Was there another ejection charge on the apogee, or was the main parachute the only event the TM was supposed to do? If there was an apogee charge, did the voltage drop in a similar fashion for that event? You say...

What kind of battery were you using to power the TM?

Cruise missile. It turned horizontal and the rail let loose when the rail button broke off. Luckily, the motor finished burning before it hit apogee, but it was going really fast horizontally. The rocket came down safely but had a substantial zipper. Definitely heads-up.

That flight was a double-fault of sorts. Not only was the rail not locked in, but the bottom rail button slid past the end of the rail and came off. It butted up against the bottom of the rail at liftoff but didn't catch the groove, ensuring that it wasn't letting go. Individually, those two...

Always check the rail to ensure its locked into the launchpad. Full disclosure: this wasn't my rocket, but I helped a friend put it on the pad.

I saw this thread and ordered from them on 28 Jan. It shipped out within a week and arrived two days ago. I ordered tepanol and lecithin, and was a returning customer. It all arrived just fine and I have no complaints.

You’ll need another sensor to periodically correct the drift. However, our rocket flights are usually 1 minute or less. Within that timeframe drift is usually minimal. Drones typically will use the accelerometer to do this when in stable flight, but it won’t work for rockets.

I sent you a DM. I see a few things in the code that might need fixing. The fact that its giving you nearly stable values in 2 axes makes me think it may be a calibration issue, or a simple sign inversion. I'm also not a big fan of the MPU6050. If you look at the datasheet you'll see that it...

Oh, I missed that. Yes, a 1ms delay is fine. That will work. My bad

Looks about right. What is the output data rate you set the MPU6050 to? Since I dont see any delay statements in your code I suspect you are probably sampling the gyro faster than it is outputting data. This means that you think you might be getting 2000 samples, but in reality you are...

Other folks may tell you different, but I recommend you only use the gyro outputs with quaternions to determine the rotational attitude of the rocket. It will be important to calibrate the gyro so that the drift isn't too bad. You can determine the gyro offsets by sampling the gyro when its...
