24 years ago, Winamp was released for Microsoft Windows OS and quickly becomes the most famous software for music reproduction. In 1998 Winamp's version 2.0 was released, allowed to create new skins and bring the community the oportunity to program PLUGINS. By the end of 1998, th … | Continue reading

Words are updated "in place" by quickly/strategically injecting backspace characters. * Runs on a … | Continue reading
Almost every electronics device uses some kind of a microcontroller nowadays. The thing is, that these chips can be very complicated, and even though you can buy them very inexpensively (like Arduino for example), I've still wanted to take a deeper look into them and un … | Continue reading
After a decade of dual-booting Linux, I got tired of waiting around to change the GRUB boot selection any time I wanted to boot Windows. With a little tinkering, here's a physical switch that determines the OS to boot each time the computer is turned on. | Continue reading
In 2020, I developed the PERSEUS-7, a minimum configuration version standalone computer with the 6502 CPU. On the PERSEUS-7, It can run software up to 1kB, but I need more memory space to implement simplified floating point interpreters and so on. Therefore, I started to develop … | Continue reading

Given that the CL-GD5429 on the Beckman motherboard only has 512KB of memory, yet supports 1280x1024 modes (and 1600x1200 interlaced), I began to look into ways to support higher resolution modes about a year ago, sometime in early 2016. 1280x1024x4bpp uses 640KB of video memory. … | Continue reading
My mother-in-law recently gifted me a bag of the family's retired iPods. I had forgotten how good it feels to hold and use one of these things. Naturally, I decided to modify one. I wanted to supply some modern features (streaming, search, Bluetooth audio, etc), while paying homa … | Continue reading

When Geoff's PIC32-based board got full VGA resolution overhaul there was a rather important consequence. The frame buffer became larger than the original and with that I had to reduce UART receive buffer. The latter change caused buffer overflows to happen much more often a … | Continue reading
Because a lot of people liked my previous gift card (Fully 3D-printable wind-up car gift card: https://www.thingiverse.com/thing:3308710 [https://www.thingiverse.com/thing:3308710]) and asked if I could create another version of it, I decided to make this Leonardo Davinci inspire … | Continue reading
Star Trek was known for dreaming up technology that was deemed nearly impossible given the limitations of the technology for the day. Having a small badge that could send audio across vast distances seemed out of the realm of possibility during the late 1980's. This project's aim … | Continue reading
I wasn’t always the world’s foremost authority on anything and everything to do with electronics (well, this is what my dear old mom believes and what she tells her friends, and I’d like to think I’m not the sort of chap who goes around disagreeing with his mother).When I first s … | Continue reading
I recently found WS2811 addressable LEDs on Amazon and I thought they were awesome. I had an idea to control relays using the addressable LEDs and as a bonus, that the outputs would be opto-isolated and they can link to multiple light strands. There are a few firework controllers … | Continue reading
