We're building a repairable and more sustainable ebike battery at https://infinite-battery.com :)

Very nice, looking forward to a deal with Décath' ;) How hard is it to make it compatible with the various motors when there is communication involved? I've been wondering for a while if the display on ebikes could also be a more open and durable part of it.

Thanks! We're compatible with Bosch, Bafang, Brose, many others! It's just a matter of implementing a simple protocol each time :)

as an avid analog biker who enjoys seeing more folks get into cycling via their ebikes, I love this!

Thanks so much! Appreciated

Building https://check.supply : the easiest way to mail a real paper check from your iPhone. Link your bank, type the amount, and we print + mail it for you — with optional certified or express USPS tracking

I built this same thing about 15-20 years ago, there was no plaid so I just had them input their routing and account info, I could print anything I wanted on the MICR line so I don't see why you need access to a user's bank account (seems intrusive to me). Also, at that time, I had trouble getting people to pay me even enough to cover postage so bravo to you if you have people paying you $7/check.

I don't have links to share, because things aren't ready for primetime.

- A SAAS to help HomeSchool Coop and Collectives build an online presence where they set up member registration, show course offerings, and let parents enroll their students. Main competitor is HomeSchoolLife and this started because our own HS Collective used HSL and hated it; so I thought I'd try. The complexity has grown rapidly, trying to custom roll a CMS because I couldn't get Wagtail to integrate nicely with my site, and Django CMS leverages the Django Admin but I don't want my users to have to deal with that.

- Also playing around with a SAAS targeted at YouTube Car Flippers to be able keep tracking of their current flips and, eventually, research new potential flips.

- I've got plenty of other unfinished projects that I still tinker with; a real-time version of Words with Friends, because I hated the slow asynchronous gameplay. I started it 12 years ago and then life got in the way. I'm guessing WWF probably has this mechanic now; I don't play anymore.

I’m building SPARK (Signal Processing Algorithms, Routines, and Kernels), an open-source library of modular, efficient DSP components for low-power embedded audio systems. The goal is to make it straightforward to design and deploy small, composable audio graphs that fit on MCUs and similar hardware. The project is in its infancy, so there’s plenty of room for experimentation and contributions. https://github.com/Col…

Nice! Unrelated to the other open-source SPARK for designing and deploying small, composable data processing graphs with a Python API, I guess? Are you thinking about supporting deployment on FPGAs like the iCE40 line?

Currently FPGAs are out of scope. But, would love to implement that use case as well in future.

I've been working on Listening Facts[0] for a while now. Basically, it's a year in review of your listening facts presented in a "nutrition facts" label format. It works with Apple Music, Spotify (via waitlist due to recent API changes[1]), and LastFM.

I'm currently working on language detection to expand the "facts" with a language distribution on each generated label.

I tried getting Adsense on the website but I keep getting denied on "Low Content Value" grounds. I tried some alternatives but the quality of their ads was ridiculous (stuff like "your device has a virus, click here to clean it up") so I just gave up on that.

Here[2] you can find what one of the labels looks like and many more from some user submissions

I'm working on rustnet (https://github.com/domcyrus/rustnet) which is a cross-platform network monitoring TUI built with Rust that provides real-time visibility into network connections with deep packet inspection.

Currently I'm spending numerous hours trying to package for multiple Linux distributions. I have to say that building for Ubuntu using the Debian build system and Launchpad seems like a way to spend days for nothing except frustration :) Maybe the problem is also me / PEBKAC

I have been working on a simple SAST like AI code scanning tool. Currently it only uses OpenAI API to do the scanning but maybe if I get access to other APIs I can add them. There are still a lot of features I would like to add but I am building this in two parts, the CLI scanner and the web management UI. At the moment the UI and scanner run together but eventually I want to break this out so that the scanner can just report findings to the UI remotely. This would be nice if running from a CI/CD environment. I eventually also plan to add some sort of scoping to the scanner so it can be targeted to new branches.

Posting this as maybe it will help other orgs out there that are looking for SAST and want to do it cheaply. https://github.com/jdubansky/sassycode

A few weeks ago I participated in a Nano Banana hackathon and built a mobile app that takes photos in different decades. Its called Time Machine: https://apps.apple.com/us/app/time-machine-retro-camera/id67...
