Oh, at last a open 2D printer! I've been waiting for this. If it's successful, It'll be the last printer I buy.

Open Printer

Finally, an open hardware printer you can actually understand, repair, and upgrade

Took another photo, tweaked settings to get the colours closer to the display.
Ah ha!!! I ordered the display with a font chip, which has an 8x16 font on.
After much work that now works fine, giving me 37 lines per screen by 128 characters.
It does have a Yen/Yuan symbol instead of a dollar, but there is a variable width font with the dollar, so I can in theory swap the Yen/Yuan for a dollar on the fly later in assembly.
The viewing angle and contrast on this panel is also fa better than the previous one, image is a bit washed out still.

I got text running, but the font is 12x24, and there is no 8x16 sadly :(
So only 25 lines on this screen, but 85 characters wide.
Would be nice to get an 8x16 font on here :(

#LT6502b screen is now alive, just a solid block fill for now, but it’s working. 16bit colour and 1024x600.
Text will be the next thing to get working.
I will say, wow it’s a complex screen to setup.
Stressed cause the world's on fire, but I keep moving forward. So I gave N3RD some whimsy #maker #robot

Moved my projects out of gitslop into #Codeberg https://codeberg.org/TechPaula

I will delete the gitslop repos in a couple of weeks.

Adults Lose Skills to AI. Children Never Build Them.

Discussions of cognitive offloading often miss a critical distinction: What AI does to a 45-year-old's brain is categorically different from what it does to a 14-year-old's.

Psychology Today

More and more I think we need strong social norms against using LLMs in 'write mode'.

When they're used in read mode, the only person they're misinforming is you, the twit that decided to use one. In write mode? They've got the ability to disseminate false knowledge to others, an actively hostile and anti-social act. This should be seen as akin to littering or fly-tipping.

At the absolute minimum you have the social responsibility to admit that the artifact you brought into creation was done so with a language model to minimise the fallout to others. Ideally, don't publish it at all.
