Introducing Regenerator 2000, an interactive disassembler for for C64.

TUI based.
Extremely fast.

The RPi is running a custom program I wrote using @ricardoquesada.bsky.social's bluepad32 to handle the Bluetooth and game controller link, then feeds the button presses over the Photo! link protocol.

Updated the algorithm to trace the pixels. Easier to embroider 16bit sprites, but still a lot of room for improvement. #embroidery #retrogaming #outrun

Gun Fight (arcade, 1975) as embroidery in two t-shirts.

I like representing a video game in two t-shirts.

First time using linen: good. But don't use fusible stabilizer with it!

We've started development on Return of Fury 2 for the #c64 ! Milestone 1 is close, so I wrote up a little introduction on what's been going on.

Creating a machine-embroidery angler fish with a blinking LED Long story short, about 6 months ago I started a new hobby: machine-embroidery. Since then, Iโ€™ve been experimenting with machine-embroidery pixel-art. The Angler Fish is my 18th machine-embroidery pix...

This is how I created the machine-embroidery angler fish with the blinking LED.

Went to a coffee shop in Pescadero, CA (e.g: in the middle of nowhere), and the had a B.C comic book.
And guess what ? I was my B.C's T-Shirt (the one I embroidered a few days ago).
Coincidence ? I don't think so.
The Gods are telling me something ๐Ÿ˜‰

Another classic: Space Invaders.

Trying two new things:
- 8mm pixels for the logo
- 1.3mm pixels for the font

I like the end result. However, I should increase the pull compensation for bigger pixels. And perhaps try 1.5mm fonts.

A classic this time.

Forgot to add the topping, but I like the result very much (much better in person)

So happy that I created an editor that defines the path, pixel size and other variables. So easy/fast to create the file for the embroidery machine.

Used "pull compensation" of 0.25mm.
Needle: 90/14
Stabilizers: double. No-show mesh fusible

I liked the end result... except that it is not totally centered... perhaps one cm to the right.

I've been working on a "Pixel Embroidery" editor.
Has some nice features like the "Partition Editor" and "multiple layers". Impossible with my previous script.

Thanks to the "Partition Editor" I was able to reduce the "jump stitches" to a minimum.
