I know the right wing media finds it all very difficult so, in an attempt to be helpful, this is what an actual interference with free speech looks like.

Been having lots of fun with @charlie.daft.games‘s Red Alert port for RP2350. I’ve got it working with my HSTX driver and just got PWM sound working as well!

Using both PSRAMs together we can get enough bandwidth for 720p. Can’t easily write to a back buffer while displaying though as the PSRAM is constantly busy, but can do an image slide show! The RP2350 decodes the next jpeg from flash during the time the monitor is blank.

Got the double buffer, one in each PSRAM, up and running. This is 800x600, RGB565, which is fairly close to maxing out the available bandwidth.

My Tiny Tapeout 9 project running on the FPGA board. Got to have some Bad Apple when testing new hardware!

Well this is right on the border line of working, but it does seem to be working! 1080p48 output, running the RP2350 at 1.5V

Got the new @gigspanner.bsky.social CD in the post! Hooray! Minor problem, I seem to have no working CD drive... I have an old removable one, but it doesn't want to work. And my old laptop I used last time I needed to rip a CD doesn't seem to want to boot any more.

Feels a good day for a thread. So I would like to introduce you to a mostly forgotten, but actually rather pivotal figure in PC history. Meet Dr Portia Isaacson Bass. If it wasn't for something she did in 1981, we'd all still be forced to use IBM (or IBM-licensed) PCs right now. /1

Finally put in an order for the PCBs I’ve been designing recently. First time trying JLC’s standard service, to get a BGA FPGA part and some 0201 capacitors on the boards. Had some fun with KiKit getting the two designs into one panel!

Anyone know what's up with www.lcsc.com/product-deta... showing "The part does not exist"? And I just tried to order some RP2350A through JLC for PCBA and the order was declined.

Finished V2 of the truncated icosahedron, and I'm very happy with how it turned out. The sides are 32 hexagonal and pentagonal PCBs, joined by 3D printed corner connectors and covered with 3D printed diffusers. The pixels are mapped and it's running 3D animation patterns on a Pixelblaze controller.

If you’re ever in Dublin, I would strongly recommend the Guinness Open Gate tasting room. Avoid the tourist trap priced paddles and just have several halves of the different beers they brew - they had some really interesting ones on today!

Fiona Fox’s recent article in Research Professional News cautions that expelling Elon Musk from the Royal Society could undermine public trust in science. I disagree... 🧵 1/25 www.researchprofessionalnews.com/rr-news-uk-v...

Nice to see Adafruit doing cool stuff with my DVHSTX library That coloured text mode was fun to put together, the font is antialiased which is why it looks so good!
