@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

@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...

@drfootleg "XYZZY" RTABmap for now but somewhere deep in "twisty little passages all different" I hope to find:

This is a huge step forwards. Finally worked out how to over-ride the screen clearing to not-quite-black on the Tufty2350 Badge OS. Significant frame boost and the game now displays the same on the badge as in my hardware emulator. I may keep the blue background splat mode as a debug tool. #pimoroni #badgeware

@rpimag I wrote a hardware abstraction framework so that I could port #MicroPython games written for a specific device to run on any hardware. Here is an example game where the exact same code module is running in Pygame on a computer where I can debug in full Python, and on the https://badgewa.re Tufty2350 badge from #Pimoroni. The game module has no hardware dependencies. All hardware access is via a class passed in, providing the methods needed to interact with it. #MakerMonday

Finally nailed the bugs from my refactoring of this game code. They were mainly due to hard coded assumptions about screen resolution in the original which I had not spotted. I now have it running beautifully in Pygame in any window size I want. More rocks! #retrogaming #badgeware

Good progress tonight. I wrote a Pygame emulator for the #Pimoroni https://badgewa.re Tufty2350 badge app framework with MicroPython equivalents for various hardware classes, allowing me to start debugging and enhancing this asteroids style game which was written in MicroPython by GitHub user samneggs

One of my quicker projects. I made a wireless air quality sensor for Home Assistant using ESPHome. #HA #MakersHour

@rpimag I installed a Raspberry Pi media player below a Swift nest box on the side of my house. It plays recordings of Swifts nesting at dawn and dusk to try and attract first year nesters to the new site as part of a Swifts conservation project. #MakerMonday

@freecad Third iteration and we have a good fit and strength to squashiness ratio. Mainly through careful selection of options in the slicer. #3dprinting #TPU

Nice little @freecad project this morning. I designed an end plug for the greenhouse gutters. Now printing in TPU to test for fit.

Fully weather proofed! My #pimoroni Pirate Radio kit from around 2019 is now installed below the Swift nest boxes and programmed to play Swift colony sounds on a corn schedule in the mornings and evenings until hopefully some young birds looking for their first nesting site move in. #swifts #RaspberryPi #birds

Tonight I lost a couple of hours debugging a #MicroPython issue which was new to me. My code crashed when I added a simple function. It crashed before anything in the code appeared to run. I commented out the new code and it still crashed. I learned that triple-quoted comments consume RAM and I had hit some limit. I discovered this was the cause after 2 hours trying to find the error in my code which first caused the crash.

@MakersHour I already mentioned it. #Makespace is my place of inspiration. So many creative people from different #maker disciplines. From computing and electronics to glass working, jewellery, laser cutting crafts and #3dprinting, not to mention textiles and leatherwork, woodwork and metalwork. I mentioned the lino cut printing. There is also vinyl cut work and screen printing. All in one place. #MakersHour

@MakersHour Hi #MakersHour people. Footleg here. What has inspired me this week is the artistic people who ran the Lino printing meet up at #Makespace where I was taught the basics and made my first ever lino cut prints.

No crimp connector is out of my reach now! I just did my first JST 1.25mm connectors with the new ratchet crimping tool I bought since I’ve misplaced my other crimping tool. Really pleased with this tool purchase. #Maker #electronics #MakersHour #MakerMonday

Success! Hard won over 29 hours with my #ERCFv3 on my #Voron Trident AWD 350.
No false filament runouts triggered, so my redesign of the hot-end switch is working. Just a few clogs, the usual filament unload fails and a blocked nozzle which I dealt with by just putting a new nozzle on. Amazed I saved this after so long on the print bed. -

I think my new hot-end rebuild has passed the test. Really happy with this result. #3dprinting #voron #ERCFv3

New customised Hot-end reassembled and working. So far it is all behaving. #Voron #3dprinting
