smartknob VS WriteFreely

...it's a spring and a servo. Or a brushless motor.

...or any not-bottom-end-of-market steering wheel for driving video games.

I made a rotary input device that provides software-defined "virtual" detents and end-stops, implemented using a BLDC gimbal motor. It can dynamically switch from completely smooth unbounded rotation, to having detents with configurable spacing and strength and "end-stops" that spring back if you try to rotate past them.

It's got a round LCD on the front of the knob (wired and supported via the hollow shaft of the motor) and uses the flex of the PCB and strain gauge sensors (in the latest revision, simply SMD resistors whose resistance changes when stretched) to detect when the knob is pressed down.

It's open source hardware and software - https://github.com/scottbez1/smartknob

HN folks might appreciate that it communicates with host software on the computer via protobuf-encoded USB serial messages -- nanopb is awesome for embedded C protobuf support, and having the defined schema, autogenerated serialization code, and compile-time type safety is so much nicer than ArduinoJson or hand-written binary protocols!

I'd love to get it hooked up to some real software eventually (video editors or home-assistant control are my 2 main ideas), but it's really just been a fun project to tinker with and try out some new ideas and parts I've never used before.

I'm trying to design a smartknob based off Scottbez1's design (https://github.com/scottbez1/smartknob), but with a stripped down feature set. However I can't seem to get the magnetic sensor to work properly - it's an MT6701 connected to an ESP32 via SSI.

Thank you so, so much for finding it. Unfortunately on eBay its not cheaper and ali doesn't have it cheaper either. It looks like an out of production item, like when I wanted to make this https://github.com/scottbez1/smartknob and it was gone except when sparkfun got a few.

Mastodon is a microblogging service, so not meant for large bodies of text. This is why the text entry box is small, the columns are somewhat narrow (especially in deck mode) etc.

Platforms like https://writefreely.org/ , which are designed to be for blogging and long-form writing, are the place to write this. Write Freely federates so one can follow accounts and interact with posts via Mastodon etc.

It's all about federation, in these federated networks all these servers talk to eachother and exchange messages about stuff going on on the servers. So it's easy to set up a hidden service for the webui of one of them, but it's sometimes quite obscure to try and set up the federation for one of them. It depends on what settings they honor and what other types of encryption and authentication they require and stuff. But, if you put some effort in ahead of time, you can make it really simple: I don't know how to do it in rust(lemmy is written in rust), but here's a neat example of how to do it in Go: https://github.com/writefreely/writefreely/pull/710 which requires no complicated configuration.

An alternative to Plume is WriteFreely, which is a pretty clean & simple experience. Just don't expect to much regarding customization.

I also wish write.as were more popular. It's like old Medium, but less popular but with a more reader-friendly business model and self-host-able (AGPL v3)
