Check out my latest YouTube video!
It’s about this 2m tall motorised launch pad I built:

Big thanks to @SGirl0311, @DPcbway66850 and @PCBWayOfficial for the amazing Christmas gifts! 🎄

@BooleanNotFalse A school bus would be a pretty cool dummy payload!

[Jacob Thornhill @JacbThornhill]

@will_whang @PCBWayOfficial Awesome! Are those chips from TDK Invensense? I can’t quite make out the part number

[Jacob Thornhill @JacbThornhill]

@RELIK_60 Sounds like an awesome project! I’m afraid I have no experience developing rocket motors, as it is illegal where I live… but best of luck!

[Jacob Thornhill @JacbThornhill]

I have a new video about my fin-controlled model rocket! 🚀

@Bob_Welton Sadly I still have a lot of code to write! My best guess is late this year / early 2025

[Jacob Thornhill @JacbThornhill]

New YouTube video coming later this week!
A deep dive into the workings of my latest rocket.

[Jacob Thornhill @JacbThornhill]

@rrkspace Thanks! 60m. Quite a bit lower than expected thanks to a bug in the control system.

[Jacob Thornhill @JacbThornhill]

Over 100,000 views on my YouTube channel 🎉

50,000+ for my first TVC rocket (when I was 15), 40,000+ for my flight computer PCB, and a new video recently posted…

[Jacob Thornhill @JacbThornhill]

@Bob_Welton Thanks! It’s because a third axis is needed to control roll/spin, as you said, and roll control is going to be the objective of the first flight of this rocket (before any fancy position control). This flight will be used to validate the aerodynamic characteristics of the fins.

[Jacob Thornhill @JacbThornhill]

I’m working on a fin mechanism that can fit within a 66mm airframe.

The servo motors are offset upwards to make room for a 29mm rocket motor at the centre (not pictured).

[Jacob Thornhill @JacbThornhill]

Big thanks to @PCBWayOfficial for the Christmas presents! I think the name badge has to be my favourite.

[Jacob Thornhill @JacbThornhill]

New video!

This one is about my general-purpose flight controller.

[Jacob Thornhill @JacbThornhill]

@da_lambda @PCBWayOfficial Yes!

[Jacob Thornhill @JacbThornhill]

My latest PCBs have just arrived!

Huge thanks to @PCBWayOfficial

[Jacob Thornhill @JacbThornhill]

My new multi-purpose flight controller is up and running!

It is connected to an ELRS receiver and is parsing the RC channels to control some servos and LEDs. Brushless coming soon!

It can use it’s sensors for closed-loop control of drones and RC planes.

@PCBWayOfficial

[Jacob Thornhill @JacbThornhill]

@Paul_4130 I enjoy programming these sorts of things myself :)

[Jacob Thornhill @JacbThornhill]

I have finally been able to parse data from my ELRS radio receiver!

This protocol is not open source, so I have been using Ardupilot firmware as a reference.

My software is written in C for STM32, and uses a 2-byte circular DMA buffer to parse each packet one byte at a time.

[Jacob Thornhill @JacbThornhill]

@YohanHadji Sorry yes ELRS is, but it uses CRSF to communicate between receiver and flight controller

[Jacob Thornhill @JacbThornhill]

@Siddhant__rao Yes! It’s a flight controller that is designed for use in rockets, drones and model planes

[Jacob Thornhill @JacbThornhill]

I’ve almost finished designing this new circuit board!

Any guesses on what it is?
