Announcing Regenerator 2000

I am excited to announce the release of Regenerator 2000, a modern take on the classic Regenerator tool for the Commodore 64 and other 6502-based computers. Regenerator 2000 is an interactive disassembler for the CPU 6502, focused mostly on Commodore 8-bit computers. It features a modern Terminal User Interface (TUI) with features like x-ref, undo/redo, arrows, keyboard-driven navigation, and more! Better yet, it is multiplatform and runs natively on Windows, macOS, and Linux. ...

Knitting Hello World

I’m learning knitting, not sure for how long I’ll keep it up, but this is my “Hello World” project, a kind-of scarf. I wanted to do a scarf, but I run out of wool, so I created a “small” scarf, which in spanish is called “cuello”, but I don’t know the english word. It uses mostly Jersey stitches, but every some rows I did a “knit-knit-purl-purl” stitch (I don’t know the name of that stitch). ...

Machine-Embroidering The Great Grossini

Haven’t you heard of Grossini? The one and only? The best ever magitian? Shame on you! :-) In 2006, with a group of friends (nubis, leito, lucio, tenuki, alecu, chaghi, pabloz, riq, facundobatista, yaco) we created a video game called Typus Pocus. And the main character of the video game was Grossini, a sort-of failed magitian. We had a lot of fun creating it, and created a few sequels were Grossini was, again, the main character. ...

Embroidering International Tennis

Who remembers the Commodore 64 video game “International Tennis” ? Although it was not one of my favorites games, I enjoyed playing it. In any case, a friend of mine and a very good tennis player is moving abroad so I decided to give him a little present: Even though this looks like an “easy” embroider, the tricky part was the different pixel sizes: I used the “layers” features from Pixem, where one layer had one pixel size, and the other a smaller one. But in order to export the layers correctly I had to use some GIMP editing. ...

Embroidering Outrun

The challenge with the Outrun sprite is that it has multiple colors, but many islands of only a few pixels, so it requires multiple jump-stitches, or so I thought so. To prevent the jump-stitches I decided to connect the different “islands” with a run-stitch. I modified my Pixem editor to do that, and I embroidered the t-shirt. The run-stitch path is “smart”, in the sense that it will take shortest-path, but the weight is measured by color difference. This will prevent a black stitch running over a white if there is an alternative path going over brown. ...

Your first embroidery machine

I’ve been asked a few times which embroidery machine. Here are the things to take into account: Budget and Hoop size The bigger the hoop size, the more expensive it gets. As en example, here are 3 Brother models: Hoop Size (in) Price Machines 4x4 ~$500 Brother Skitch, Brother SE700 5x7 ~$1000 Brother PE900 6x10 ~$2000 Brother NQ1700E It is worth noting that once you purchase a machine of a certain max hoop size, you are stuck with it. You cannot replace the hoop with a bigger one and have a bigger embroidery area. The limitation is in the mechanical arm. ...

This past Saturday (2025-07-19) I went to Open Sauce. And since this is a maker event, I went with my best t-shirt so far: the Angler Fish. But it had some issues that I wanted to fix before using it again. The two improvements that I made are: Added a pocket to place the battery and the microcontroller Improved how to attach the cables to the LED The pocket ...
