Code CAD for laser cutting · runs in the browser · free and open source I make a lot of things on my laser cutter, and for years the workflow has been Inkscape plus a Python plugin to generate the finger joints. It works, but it’s fiddly. Every design is a pile of shapes I …
VR games in the browser · Meta Quest 2 and 3 · nothing to install Put on a Quest, open a web page, and you’re standing on a stone plaza at dusk with three swirling portals in front of you. Walk into one and you’re somewhere else: loading a cannon on a hillside, shooting inside …
Free browser tool · nothing to install Type a word, draw a shape, or drop in a photo, and Stereogram Studio turns it into a hidden-picture stereogram: the kind of noisy poster that suddenly pops into 3D when you relax your eyes. It can also make red/cyan 3D-glasses images that look like plain static without …

Browser game · about 20 minutes The screen shows nothing but TV static. Put on red/cyan glasses, turn the dial, and a face rises out of the noise. She is trying to tell you something, but her voice comes through as whistles. Play Channel Thirteen GlassesRed/cyan or red/blue 3D glasses. Cheap paper ones are fine. …
Reverse-engineering a Hunter ceiling fan remote My ceiling fan came with a hand-held 433 MHz remote that — like most of them — was starting to die. Hunter sells replacements, but they won’t show up for a week, and the OEM remote isn’t smart-home friendly anyway. I wanted the fan in my LCARS smart-home dashboard, …
Recently the coding ability of free LLMs has increased a lot. I’ve been playing with generating javascript and came up with a simple game: http://www.bposhaughnessy.com/nestegg.
Testing UIO Interrupts Over the last few posts I’ve been building what I consider to be a general purpose project for zybo. I have two GPIOs, one connected to LEDs and switches, and the other connected to the RGB led and the buttons. I have an axi-dma as well. The axi-dma and the GPIOs are …
Making a bigger FFT In our last post we made an HLS project with the top function “fftTop”. In this article I’d like to change a few things around. First lets make the FFT much bigger. We are using an FPGA for this so it won’t bog down the processor at all, I want to …
UIO Drivers The UIO drivers are the ideal way to interface with your own FPGA blocks. Generally speaking FPGA blocks are going to be configured through a group of registers from software, and then data will be passed through them, either from an external interface, or through streams to/from an axi-dma block. We therefore …
Later on we are going to need to look at adding ubuntu so we can download packages and whatnot. Since there are kernel modules being built here I don’t think we can just drop in the ubuntu rootfs unchanged like in most tutorials. I wrote this largely as a log for myself to refer to …
