Coming soon, the Sprite hopper vehicle! Built to test GNC with longer flight times, using an EDF+Afterburner for propulsion. Should be about 70cm tall, several kg in mass, and fully autonomous! CAD is missing 8975632498723 components rnpic.twitter.com/3hPLXHDZ54

Sprite's TVC vanes at work! These vanes are 3D printed out of PLA for now, but
@split141x has generously machined the flight units out of aluminum, which will arrive soon.pic.twitter.com/OWMtdMF5yUHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -
Not as expensive as you'd think ¯\_(ツ)_/¯ https://www.mcmaster.com/76155a29 https://twitter.com/ayyitsjameslmao/status/1224433975470379011 …

Position and velocity looking good! Lifting off is hard from a sloped surface, which isn't that surprising. Lots of ways to fix that either in software, or with just a few shims :)pic.twitter.com/JsDD5L8iKX

Still really fighting for good altitude control, one of the hardest parts of the project for sure. That said, position and velocity are in the loop now! They still need their own round of tuning, hoping to dial that in today.

The most dangerous parts of flight are liftoff and landing. Dropping from 5-10cm on landing is safer for the control system than getting all the way to the ground. I'd also like to punch up harder at liftoff for the same reason.

Altitude control is much more smooth now. I added a tiny throttle punch function that helps dial in the nominal hover throttle at liftoff, hence the hops. I can explain in a video later :) Better video if you want to watch all the telemetry: https://youtu.be/GgvhNoL0v7U pic.twitter.com/N7BMUgEO6k

We've exceeded some sort of limit and doc has collapsed in on itself like a dying star. This was the last thing before it shut down. Thank you for participating in this experimentpic.twitter.com/hI9G7KMINP

10/10 chance of regret - I made a to do list for software tasks to complete tonight but anyone can contributehttps://docs.google.com/document/d/1ZiqIreXHO_UkjVSL_o6gJmkv5-pZs6pC2EWq-BIms-I/edit?usp=sharing …

I’ve been workin on my roasted veggies game for a little while and lemme tell you, I’ve got this DIALED. Go hard on the pepper, go easy on the garlic. 450F for 10 min, you wanna burn em just a smidge, then it’s down to 425F for another 10 and you’re golden.

Some of these things will come up in future videos of course, but priority goes to the folks who make BPS possible :)

Tomorrow at 4pm ET / 1pm PT, myself and the fantastic
@brianbdouglas will be giving a small live streamed presentation on control systems(TVC, GNC, Kalman filters, etc) for BPS Patrons.https://www.patreon.com/posts/control-systems-33563465 …Prikaži ovu nitHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -
Closing the loop on velocity control in the software for Sprite tonight, position control coming soon. In the meantime,
@Split141x has been machining the TVC vanes for flight! He's been filming a bunch and progress is moving right along, should be a few fun videos about it soon!pic.twitter.com/BvhuGX8m7V
