I built 3 electric cars from 2018 to 2023 and drove them 20k miles. My own firmware and controllers, with an https://openinverter.org motor controller Now I release my knowledge in bite-sized chunks on my new YouTube channel to help others: What's a battery management system? https://www.youtube.com/watch?v=_QsMoCrSTYc What is the C-Rate? https://www.youtube.com/watch?v=dDu1fRtKfsA What is battery balancing? https://…

You are the closest I have found to this, even though it is a digression: Do you know of any communities with self-built airplanes? (especially novel-esque designs for propulsion or wings?) I realise these have far more regulations, but experimental GA is something that really excites me.

I do not. I know people use https://openinverter.org for boats

Just yesterday I stumbled upon https://vesc-project.com/forum where they are doing something similar with a focus on ebikes and drones.

You are talking full-sized aeroplanes right? I think some of the sail-gliders can be homebuilt, there must be communities for those guys.

I'm working on a social network based around link sharing!

One of the core ideas is that rather than following a whole person, you can follow a subset of their tags so someone can post about obscure cheeses and ambient electronic, but lactose intolerant you can just follow the music. Or you can follow someone's tech posts but not follow news of their dysfunctional city.

Honestly a lot of it is resurrecting ideas from earlier days in the web like Digg and Delicious, and despite having the idea for ages and having worked on it for a decent while, it's only getting more relevant as the web gets more algorithmic and external links get demoted in sites like Twitter.

The aim is to bring more curation and humanity back to the web, and the next feature I'm really excited to get out is one to make in-person conversations even better!

It's already live @ lynkmi.com and if it's of interest to you, you can sign up to the waitlist (it's very short)

I'm working on a 3D infinite canvas of text, focusing on code. Runs on iPhone, iPad, macOS so they can all act as separate viewports into a space. You can point the app at a repository, download a copy locally, instantly render the entire repository into space in less than a second in most cases, and then fly around and search for text. I just got an optimization working for larger files and it's kinda fun how much e…

That looks incredible! How did you learn Metal? The documentation on it from Apple leaves a lot to be desired for learning it from scratch and all the books I’ve encountered look woefully out of date.

Well first and foremost, by doing exactly what you're doing now and asking a bunch of people for help too, haha. It's not been easy, and I'm truly still terrible at it.

However, honestly, most came from following this tutorial series on YouTube which broke down building a basic game engine, and I stopped about 20 or so videos in once I had the tools I needed. I highly recommend!

And hey feel free to DM me on something if you'd like - I'm happy to answer questions and help where I can!

I’ve been deep down the rabbit hole of custom mechanical keyboards for a few years now, and I’m now taking the plunge into designing my own PCB with KiCad. It’s been a very interesting project! It’s a split keyboard, inspired by the Sweep, but with 2 extra keys.

I'm on my fraternity's alumni board. The chapter has been using spread sheets for everything since I was an active member. Every year, information about recruitment gets lost in the shuffle between officers.

I've been working on a bespoke CRM for them to prevent the spreadsheet rot while providing some helpful visualization and making their data easier to use in the feature. The goal is to make the entire recruitment process self documenting.

Its slowly evolving into a way to keep track of actives and alumni, as well as ways for actives to interact with the recruitment process.

For me the most important issue that needs to be solved right now is the increasing urban sprawl and the car dependent neighborhoods. It causes social isolation. Maintaining infrastructure like roads and electricity, is causing a strain on the economy for local municipalities. Not to mention the disastrous effect car based transportation has on the environment. I am a fullstack developer living in Norway. Last year I…

That's the kind of projects I love to see. Actually socially useful :) Keep it up!

Thank's a lot! So far the project haven't paid off much. But that is not the most important goal. It is about making something really useful for people. In this case nice cities and neighbourhoods.

To get some experience launching webapps that can be put into the play store and play around with image generation models, prompting, I am building an app to generate application/corporate photos from a few non-professional selfies.

Tech stack is probably FastAPI (I mainly know python) and likely nuxt/ionic (none/not much experience). Not sure how the whole hosting, interaction with replicate/huggingface will work on phone apps, payments on stripe without having a company, how to make the webapp into a phone app, etc. It should be a great learning project with the first time scoring an actual sale! Happy to hear early guidance if people have done similar things with python backgrounds to get started.
