https://makerworld.com/en/models/1823464-3d-chrome-dino-with-stand — published my first figure design, it's an iteration of the design I did for laser-cutting last year, but it's much easier to manufacture as it doesn't require any supports and post-processing, and only takes ~0.75g of filament to print.

#KaitaiStruct, a cross-language binary format parser generator, released a new major version 0.11! Java and Python serialization, partial object tree in the Web IDE, import fixes, `valid/in-enum` to enforce defined enum values, null-terminated UTF-16 strings and much more!

Was scared to test whether my new level shifter board or the new card breakout will actually work, and today I finally got brave enough to connect everything and power on.

I can sniff the organizer-to-card communication now and should be able to implement a card dumper as well.

I'm trying to improve https://github.com/mblsha/binja-scumm6 to fuse instructions together, so that Binary Ninja won't struggle with decoding too many push/pop instructions by itself.

To make it work I need to generate unit-tests that try to disassemble the bytecode, and in order to write them I need to find the discrepancies between a reference implementation in descumm and what I currently have.

Bespoke UI to highlight the differences and make data-annotation easy sounded like a good idea, so here it is.

And it fits the new camera pretty well now!
@pmarheine helped me use a CNC router to precisely convert an #RRS D800 L-plate to fit on a D850, and the machine did an awesome job. All I needed to do is to manually file the remaining metal bit to make it fit flush.
Tried tracing all the connections of the IQ-7000 organizer (in Figma), and marked almost all of them in a few days: https://www.figma.com/design/6VscbLm1Nu1IrMICPUrrYi/IQ-7000

Also using a high-megapixel camera with a macro lens and flash makes PCB shots pretty easy. 100% crop, but not sure whether mastodon will downscale it.
Looking at Sharp IQ-7000 PCB trying to trace all the connections, and they did appear to break the traces using drill holes, they're not vias. There’s quite a lot of them.
https://github.com/bitbank2/FastEPD library manages to produce pretty fast animation times on some ESP32-S3 epaper displays. This is a demo of 100 rectangles with partial updates.
