Hi all! I wanted to thank you for the patience while updates and videos are more sparse than usual. Things are going quite well, there's just lots of boring work going on. Over the next month or two, I'd like to focus on higher quality edited videos for the BPS channel instead of live streams, and to do this I've been working hard to bring Thoomp and Sprite online.

Thoomp is the silo-ejected model rocket. I provided some details on it a while ago, you can find those here: https://youtu.be/OUbYZPGv7ho Right now, both the tube and launch vehicle are about ready to go! I've got a few flights planned for the system, and those should begin next week. Most of the boring work is just me running cables and pneumatic tubing up and down the launch tube. That, and a billion hours of cable harnessing CAD work :)

As for Sprite... oooof.... get ready for some super cool flights this fall. Sprite is the EDF/Butane powered hopper/lander vehicle I'm building. We're still a little ways away from flying Sprite, but just about all the parts needed to build it are here! We've got a fancy IMU, a CNC router for the high-precision TVC gearing, the massive flight batteries, the flight computers, the EDF, and lots of other fun things. 

There's so much more to come, and very soon, but I felt bad that I hadn't posted an update in a bit so this is just a quick one before I can get a proper sit-down Patreon update video next week! OH, and we should have a new landing test pretty soon too ;)

Blue skies,

Joe

It's always good to hear the updates! And good luck bringing up a brand new IMU... What kinds of specs are there on IMU quality?

Thanks! It's crazy, should drift a maximum of 5 deg per hour on gyros alone. Sprite flight times should be 3 min at maximum so with dual GPS and a secondary lower quality IMU on board we should be all set. It's a VectorNav VN300! They're a sponsor of the project, once I've got a bit more to show I'll produce a video about it.

Still busy to read all the books as you requested for the course! So I am glad to get some extra time.

Has any CAD of Sprite been released?

Do you have an idea when the next landing model rockets video will be?

Not yet - once we get a launch of Thoomp done I'll pivot to Sprite. Right now it looks like a big 3 dimensional X. CF 10mm rods sticking out from each "vertex" of the vehicle so they act as a roll cage for rough touchdowns. Charlie is helping with afterburner design and aluminum mill stock just showed up so I can get some experience with that. Might be able to make the thrust vanes out of graphite but machining them is tricky. Sorry, that's a lot of random info - I can put together a video about it soon!
