Nice to see YouTube showing adds that deliberately try and mislead users.

Introducing VectorSearch.js (star it & I'll continue to work on it)! A JS lib that allows you to perform semantic search over millions of vectors in ms, & can visualize embeddings too!

Pretty impressed this worked. Back when I was doing my PhD simply extracting the numbers from an image reliably would have been a good result.

Nothing like scratching your own itch. Wanted a nice easy way to convert from ZX Spectrum SCR files to PNGs. There are some nice command line tools for doing it, but here's my web version. www.esp32rainbow.com/tools/scr-to...

Started ordering components for my ESP32 Rainbow - we've got a lot of displays coming in the post! open.substack.com/pub/esp32zx/...

That's a lot of displays!

I've started locking down components - we need to get ready to kick off production!

Keyboard is a bit useless on the T-Deck. But this is running the same software as my ESP32 Rainbow.

It works - but unfortunately without reprogramming the keyboard controller it’s pretty useless.

Took a nostalgic trip back in time to play with some tape loading. The sounds really do bring back happy childhood memories (and the memories of "R Tape loading error"...) youtu.be/sTRcuNMziwQ

Trying to tidy my workbench. So far I’ve managed to redistribute the mess onto another table. I now have two workbenches to tidy… check back tomorrow to see how many additional workbenches I’ll be tidying over the week…
