<p>I'm working on a local desktop app for inventory and production management: <a href="https://kitted.site" rel="nofollow">https://kitted.site</a><p>It includes bill of materials, purchase/production orders, "can I make n?", stock takes, multiple stock locations, and barcode scanning. It's aimed mainly at small business and makers for the time-being, but still allows multiple users to connect over the the local network.</p>

<p>I started building this for my dad to help track stock for his small manufacturing business, including reorder levels and answering "can I make x of this?". It's grown to include bill of materials, stock takes, purchase orders, and production orders, and aims to compete with spreadsheets rather than existing tools.<p>It's a local desktop app (Electron and SQLite), so there are no ongoing subscriptions or data sovereignty concerns, though you do pay the Electron RAM tax.<p>There's a 30-day trial with no feature restrictions at <a href="https://kitted.site" rel="nofollow">https://kitted.site</a>.<p>I'd be delighted to answer any questions and take any feedback.</p>

<p>Mithril.js, for both work and personal projects. There hasn't been a major release since I started using it ~4 years ago, which is lovely in the otherwise churning sea of frontend development.</p>

<p>That sounds really interesting. I'm afraid we're not looking for interns immediately, but the next phase of the project will require more people and square-footage. My email's in my profile, let me know!</p>

<p>We did look at the idea of letting people arbitrarily arrange a string of LEDs then somehow map the sub-models to the new positions (which LEDs are "left eye open", which are "mouth shape E", etc.), but we couldn't find an LED string we liked that was both cheap and individually-addressable.<p>Also on the drawing board  was some sort of "tiles" of letters which would be be rearranged by the user and illuminated in a fixed grid, then have different messages light up like a wordsearch. It could also be used to make those "word clocks" that are out there, that spell out "it is half past four" for example.</p>

<p>We're working on "life support systems" for algae photobioreactors. This includes monitoring the health of the algae, monitoring and controlling the environment to optimise algae growth, providing feedback to users on growth and experiment progress, and uploading data to our own cloud.<p>We're more software than hardware, but without the hardware capability we wouldn't have been able to attempt it.<p>Previously we tried little "Singing Christmas Trees" as well [0], and while they were certainly nifty, we couldn't find the market for them at the price.<p>[0] <a href="https://www.youtube.com/@pixolighting">https://www.youtube.com/@pixolighting</a></p>

<p>I wanted a simple chat history and rudimentary web searches in the terminal, so I wrote my own [0] (bring your own OpenAI API key).<p>It was a very novel experience writing the API for the simple "tools" in plain English in the system prompt (e.g. to search the web, read a website), though I never managed to make GPT4 successfully use the "execute Javascript" one.<p>[0] <a href="https://github.com/neon-fish/cass">https://github.com/neon-fish/cass</a></p>

<p>We're not out to compete directly with WLED, we think it's great.<p>We wanted more control over the subsections of the connected LED string than WLED provides with its "segments" feature. For example, the outline of the Mini Tree is made up of four separate sections (it is interrupted by the eyes and the star), but is one single model from the point of view of the firmware and the API.<p>Also, the firmware will be written in MicroPython for easier customisation. We wanted to add some environmental sensors and a real-time clock to a standalone controller for another project in the works, and it also makes customising the controller much more approachable for beginners. Of course, you can still upload your own C/C++ instead.<p>Our lighting effect sequencer will also connect to our controllers automatically to orchestrate effects across a number of LED strings in time to arbitrary audio.<p>If you don't need to customise the on-board capabilities of controllers or orchestrate effects, then WLED is an excellent choice.</p>

<p>Thank you!<p>We are working on adding E1.31, using ethernet over USB (CDC NCM). We don't have it finished yet, but we hope it will just be a firmware update once it is. Dmxsun (<a href="https://github.com/OpenLightingProject/rp2040-dmxsun" rel="nofollow">https://github.com/OpenLightingProject/rp2040-dmxsun</a>) works like this and is RP2040 based, so it's certainly possible.</p>

<p>Hello HN, these Mini Trees have a custom circuit board with WS2812 addressable LEDs on one side and a controller using an RP2040 microcontroller on the other, all inside a CNC'd Foamex PVC case. They stand around 23cm (9") tall.<p>The firmware is written in MicroPython, which can be modified or replaced. Power is provided via USB-C, which is also used for programming.<p>There is also a web-based animation sequencer to create lighting sequences in time to arbitrary audio, examples of which are on the linked page. This is similar to xLights (<a href="https://xlights.org/" rel="nofollow">https://xlights.org/</a>), but much less powerful, and we hope to release firmware to interface directly with xLights soon.<p>My colleague and I started kicking the idea for these around after making some custom circuit boards for another project, and thought we'd have a go at making smaller versions of some much larger exhibits we had made using 12 volt WS1812 bullet pixels.<p>I hope you enjoy them, Merry Christmas!</p>
