AVA: Huh, that's odd. Hey Flash chip. Flash chip: What's up? AVA: This is gonna sound crazy, but I just spoke with IMU and she told me we've exceeded the G load limit of your solder joints...... AVA: .....Flash chip?
Sooo, uh, we DID get to the moon... 's sphere of influence... So the data did get transmitted, you can see the Doppler shift which is pretty cool, but the rocket didn't hit the moon so it's gonna fall back down now. Watch your head three months from now, I guess.
You can get CC that fluoresces in UV light. Wouldn't be too helpful in midday sun, but if you can get back in the evening with a black light it would help.
Or enclose it in a "black box". Perhaps test different black box builds to balance weight and resistance. Aluminum, ABS, with and without expandable foam inside, etc.
As somebody who who has been an avid rocketry fan for probably longer than you have been alive, and who has watched with awe and amazement all of the excellent work you have done, I would like to respectfully and humbly correct your terminology upon finding the remains of the rocket. In such sad circumstances, both my NAR section and TRA section say "rest in pieces" instead of "rest in peace". Seriously, you seem to achieve on a regular basis things that I only dreamed of going back to 1975. Wonderful work!
"We have had.... an anomaly" is what I heard in my mind when it hit the ground.... (I am referring to what the woman said in the recording of the Delta 2 rocket that exploded after launch in 1997)
As an electronic engineer I found it most interesting that the components came loose at impact. Was it the solder that gave up or was the copper pads ripped of the pcb?
I was wondering the same. Maybe a combination of both. I am surprised the IC itself survived - no broken pins on the outside and since he was able to read the contents no issues on the inside of the package :O
How viable would it be to coat the components in some kind of glow-in-the-dark paint, or something that stands out under UV light? That way you could find any lost components far quicker and more reliably.
A small holographic sticker, like the "WARRANTY VOID IF REMOVED" ones, would do the job quite nicely. They're really shiny so it's much easier to spot them in the grass, and they tend to glow under UV. My other thought was, weight permitting, you could add a small EMI shield over the board around the EEPROM. It'd offer significant additional physical strength and increase the likelihood that the chip would be captured in a catastrophic landing like that, even if the chip was still ripped off the board by the shock of a crash.
Even though you lost the rocket, it's always a great feeling that the fail safes you built in actually worked when it comes to the flight data recovery. It's bittersweet, but the data is recovered and you can actually learn from the failure now.
This felt much relaxed and calm even though the whole video was about the chaos that ensued. Just reading the graphs and drawing insightful inferences. Also that catch about 'the computer picking up its own death' - so deep and chilling!
A little advice you can make some case or covering for your flight computer like planes' flight recorder concept. On the other hand, bare AVA might more attractive:)
This is by far my favorite UA-cam channel. I can’t wait for future flights with AVA! Maybe you could try to figure out how to use AVA to make it correct itself and stay straight up on a high altitude test(kind of like past videos). I’m trying to work on that myself!
First time I’ve gotten to see AVA’s telemetry in depth, had no idea of the data being sent! This is so cool, can’t wait to see you scale up on your rocket power!!!!
Hey Joe, have you considered using another flash chip (or a separate memory address) to store the previous second of data at a rate faster than 1Hz cyclically until takeoff and only logging at 1Hz until a large change is detected? That way your first
Yes this was a amazing pre thought on how to protect your data.. even Daddy Elon wouldn't have taken the time to code the boards to check for old flash data! Bravo! Just inspiring!
I've lost expensive avionics on ballistic impacts and after 50+ years I finally had enough. I built myself a rocket 'Black Box' similar to what airliners carry. It was simply a thick aluminum housing with padding for the avionic boards. Fly my 4" rocket 6 times and it worked great every time but you can't really test to see if it works or not unless you crash the rocket. On the 7th flight, the day was hot, over 110F, and people were wanting to leave so I hastily loaded the rocket and off it went. As soon as it arced over at apogee I remember I forgot to arm the flight computers. Down it came about a half-mile out on the range and no luck finding it. A few months later while out searching for the rocket of one of the schools I mentor, one of the students started yelling and waving his arms in the air. He found my rocket (the nozzle was sticking out of the ground). We marked the location, found their rocket and then went back with a shovel to dig mine out. The nose cone and recovery bay were smashed with the chute shredded, the av-bay black powder wells and U-bolts were smashed into the bulkheads as was 8 inches of the motor case. When I got home, I ground off the smashed U-bolt and althread nuts so I could remove the bulkhead. I pulled out the electronic guts and connected a new battery. They beeped out the 8,000' altitude and lived to get launched on other flights. It does add some additional weight but saved some $$$ on replacing avionics.
Glad you’re back, Joe. You inspired me to get into electronics. I’m a cabinet maker by trade, but I’ve made a few simple robots now and am saving up for a computer so I can try my hand a coding. Keep doing what you love.
Woot woot he back 2 weeks in a row. Already saw this on the second channel. Also, 3:20, you mean deploy chutes and fire charges? You said it the other way around.
Your mention of the Jet Propulsion Lab, reminded this proud citizen of Aotearoa New Zealand, of Bill (William Hayward) Pickering, A Kiwi (New Zealander) who majored in telemetry and was director of the JPL from 1954 - 1976. His group was responsible for the launch of Explorer 1 and many important unmanned space exploration flights. And that Folks concludes today's lesson in history..
Suggestion on helping solve the accelerometer hand over. Add the rocket cog frame (or main imu frame) acceleration as states in the EKF (if they are not already states...) then setup a separate measurement model for each IMU, (a_m = a_cog + a_bias + R^G_B*G... add more stuff if you like, such as misalignment estimates, scale factor estimates and cog to imu frame offsets), then you can calculate a_m for each IMU, if this number exceeds ~80-90 % of max acceleration then exclude that measurement. This way you are using a "slower" thresholding, instead of maybe switching each time a clipping event happens. and also you leverage the advantage of using a multi imu INS system... there are more stuff to be added, but these are just my humble and maybe naive thoughts... I would love to have a look at your probably way sexy code
Wow I'm 11 year's old and u have inspired me to make model rockets i always loved space i do astronomy I'm gonna have my first rocket flight soon i just need to design it
Noticed you're using a regular (linear polarized) yagi. Is the telemetry antenna on the rocket using circular polarization? Given that the orientation of the rocket will be, umm, random (possibly tumbling) it might not be a bad idea for one or both of your antennas to use circular polarization (and it's probably easier to use CP on the ground antenna given the extra bulk). You could get CP either by crossing two yagis and feeding them 90 degrees out of phase (although your feedpoint impedance will change) or look into using something like a helical antenna. Probably won't matter until you start getting toward your really high-powered flights though, depending on the amount of RF power (I assume to save power on the rocket you're probably running really low power, probably less than 1 watt.
A flash chip!? That's great! I've been trying to use an SD card to write in real time, but there are sometimes huge delays as the card writer hits a memory boundary, now I want to give this a try! What flash chip do you use? Great video as always. I love a good unplanned disassembly!
They are cheap, easy to program, holds a lot of memory, are physically small, and write fast. It doesn’t really matter which one you chose, you can’t really go wrong. Writing is fast, clearing (erasing) a page/sector may not be fast. Make sure the chip is pre-cleared before the flight. Use two of them, mark them with a dot of orange nail polish, and maybe pack the PCB in something shock absorbing. Edit: autocorrect had turned "easy" into "use".
@@peterfireflylund Thanks for the suggestion. I've been looking at a lot of chips. I'll have to learn how to program them to begin with. I gotta ask, why the dot of nail polish?
@@stochasticsignal1951 So you can find them when the rocket lithobrakes :) They are NOT hard to program, unless you find a completely weirdo one. There is pseudocode + flowcharts in the datasheet. Many of them also have easily found source code in C and/or assembly somewhere on the net.
I find no difference between a micro SD card and a Flash chip for write speed. When I capture data at microsecond intervals, I write to FRAM's then transfer the data to a micro SD card. Using QSPI also helps.
@@Spacedog49 Thanks! Writing to the internal RAM as a buffer followed by a big write to an SD isn't a bad idea. I'll have to see if I can learn a good process for that.

It's when things go wrong that you learn the most... so thanks for sharing that learning experience with us, despite the pain. It's incredibly educational. Thanks for that.
I'm curious - why wouldn't you be sending the data to the ground station AND logging it onboard to the flash chip? I would also think that having multiple ground stations scattered around the launch site would significantly increase the probability of maintaining telemetry.
It must've been impressive seeing that HPR take off in person. Also I gotta mention how the AVA board was bent and not snapped, that's a high quality PCB right there!
Could it be that the parts did not separate due to temperature change causing a mechanical jam because of thermal expansion? Keep up your amazing work btw! I have really enjoyed your videos since I started following you a few months ago!
BNO055 has autocalibration features that mess a lot of data. The offset or scaling jumping at random times. Have it in your mind. Even if you upload you own calibration data on the power up, the auto calibration kicks in again. I have wasted a lot of time before moving back to MPU9250 and a proper UKF library.
Press 'F' in the chat for AVA... I can sympathize with your situation. I've been there many times. A couple of thoughts come to mind about your failed parachute. One thing I have experienced is that when you fly at an extreme angle to "compensate for wind" the rocket will always be moving with a high velocity because it flies in an arc and at apogee there's a large horizontal velocity component. Anyhow, the aero drag on the rocket can make it very hard to separate the sections. Perhaps this is what happened? Also, where's the onboard video? It looks like the cameras were intact. May your skies be blue... etc. :-)
Did you ever think about actuating/moving fins to keep the rockets stable or guide them? I just got my L1 cert and love you videos. I want to do stuff with electronics (learning duel deployment and soldering). Where did you learn to code and design PCBs and use them? Also any ideas for anyone wanting to do electronic outside of the box stuff with model rockets?

One thing I have experienced is that when you fly at an extreme angle to "compensate for wind" the rocket will always be moving with a high velocity because it flies in an arc and at apogee there's a large horizontal velocity component. Anyhow, the aero drag on the rocket can make it very hard to separate the sections. Perhaps this is what happened?
Also, where's the onboard video? It looks like the cameras were intact.
May your skies be blue... etc. :-)
Did you ever think about actuating/moving fins to keep the rockets stable or guide them? I just got my L1 cert and love you videos. I want to do stuff with electronics (learning duel deployment and soldering). Where did you learn to code and design PCBs and use them? Also any ideas for anyone wanting to do electronic outside of the box stuff with model rockets?
FINALLY A BPS VIDEO!!!!!! Thanks!
I’d put a bid on the destroyed AVA on eBay piece of history right there
Congrats on the sponsor! Great video, mate. It's good to see you back in my sub feed. Take care and godspeed!
You should get a van with all computers and antennas on board that can work as both a rocket transport and a mobile command center
I’ll volunteer my Estes Alpha! I’ve been flying it on and off for 30 years with periodic refurbs! 😂
Seriously though great job sir!
A long time ago I worked on impact resistant boards. Maybe you can try using one as a test.
Mom can we have elon
Mom: we have elon at home
Elon at home be lookong like we bought him off of wish
In the track of SpaceX Starship, RUD on landing. Well done!
Cool to see you taking on sponsors. It means bigger and better things to come, and hopefully means you won’t ever be living out of your car :)
