@drfootleg @MakersHour Orphans with brooms can be very useful in a Makerspace, just saying. #Humbug ;)

@talktech I published C++ examples with drivers I ported to the Presto earlier in the year: https://fosstodon.org/deck/@drfootleg/114649717915312322

> ROS with real robotNot a trained ROSer, but figured out from first robot node and keyboard driving, joystick driving, adding LIDAR, and URDF for visualizing my bot in rviz2 on the desktop, up to running SLAM on the bot.
I created a custom "ROS 2 GoPiGo3 Robot Node", and then a set of guided "tests" with shell script commands to help remember how to do things.
Perhaps some useful stuff:
https://github.com/slowrunner/ROS2-GoPiGo3/blob/main/Docs/Test_ROS2_GoPiGo3.md
and the node is at https://github.com/slowrunner/ROS2-GoPiGo3/blob/main/ros2ws/src/ros2_gopigo3_node/ros2_gopigo3_node/gopigo3_node.py

@drfootleg Another tip that has been plaguing me for a month!
If you have processes inside a Docker container and other processes outside the Docker container that need mutex protection such as I2C bus or SPI bus accesses, you need to map the bus (obviously) **and** the mutex folder!
I had the sensor access working great but could not figure out why my inside and outside "mutex protected" accesses were colliding...

> ROS2 in Docker on PiOS Bookworm for Pi5
Tip: Break the build into two Dockerfiles - 1) the long base build, and 2) the experimental build steps that will fail a few times (quickly).

@drfootleg OK - ignoring that then this is the 1st error I'm getting
WLAN connection succeeded in 2 attempts!

Exception in checking message: type object 'bytearray' has no attribute 'fromhex'There is about 5 seconds between saying subscribed before anything else happens
Just going shopping :)

@concretedog @drfootleg On pondering some more, I had to go and find this clip. This should be the clip for our current technological age!

I made it onto the #Pimoroni blog!

Much improved collision detection code checked in. Plus larger asteroids on larger screens. Things quickly get out of hand now with a big game windows. It is a lot of fun!

Debugging the hit boxes in the game code, as they could do with some improvements.

My Pygame port of the space rocks game is now published for your rock shooting pleasure. Runs on the #Tufty2350 badge as well. https://github.com/Footleg/python-games

So it begins. Today I got my first email from a recruiter which was so clearly auto-generated using #AI, explaining in unnecessary detail how my skill set matches each of various coding jobs in London based on scraping my github repo.

This gravity simulation code is now available on my github. https://github.com/Footleg/python-games
The Asteroids game port still needs some work, but will follow soon.

I have now ported my gravity sim app to Python so I can provide a simple example application for my python games on any hardware project. Here seen running on the Tufty2350 badge, and on a computer screen behind. #MakerMonday
