I'm building a custom NC manufacturing robot from scratch.

I was unhappy with availability, pricing, and business model (SaaS lock-in) of the existing hardware/software solutions. But to my delight, I noticed that you just need better amplifiers to use 3D printer mainboards for driving industrial stepper motors. Everything is controlled with Gcode, which is just text. And sensors can send back logging messages over the same USB connection.

That means the control software can be just a python script with a little state machine inside :)

https://www.inclusivecolors.com/ Iterating on an accessible color palette creator, for custom Tailwind-style palettes of multiple swatches, where you can check your colors have sufficient WCAG/ACPA color contrast on a live UI mockup. You can export the colors for use with Tailwind, CSS, Figma, and Adobe. I started working on this because for design projects I was almost always getting handed brand style guides that w…

I'm a big fan of HSLuv and I've been looking for a way to generate 12 distinct colors for data visualization, so that small points in those colors against a black or dark blue background will be visually distinct to everyone including my red-green colorblind coworker.

I like HSLuv too as its color picker looks familiar while having a Lightness slider that works the way you'd expect compared to HSL. I see color nerds promoting OKLCH but OKLCH color pickers can look intimidating.

Did you get anywhere with this? When there's multiple kinds of color blindness changing the perceived colors in different ways, I'm not sure 12 colors that are distinct to everyone is feasible. You could use different symbols though, or changes in size or pattern.

I'm building Pastmaps - striving to eventually be the world's largest online collection of old maps, aerials, and photos all packaged into a public historical research platform that's as easy to use as Google Maps. This has been a labor of love now for about a year, but I still have a huge mountain to climb to realize the full vision. Give it a try and give me your harsh criticisms - that's the greatest gift you could give me!

Even in it's current state, it's being used by geneologists, urban explorers, search & rescue teams, real estate developers, government agencies, etc. The number of exploding use-cases continues to astound me and keeps me motivated to continue.

Interesting! The use of 3D printer electronics is a great idea as they are cheap(ish) and get reasonable accuracy.

I'm curious what you mean by a custom NC manufacturing robot? A CNC mill?

https://lingostories.org (not a business, just a side-project, entirely free) I'm building a website with interactive stories (or story-based games), intended for language learners. The idea is to make stories with choices (using Ink script), including features you may expect from adventure games (e.g. inventory, choices that matter). The text is written in simple language, it is then translated in many languages, an…
