Reverse engineering my e-bike’s head unit and motor controller to build a custom head unit out of a Raspberry Pi with oled touch screen (head unit will also be used to control LED patterns on the bike).

Used a logic analyzer to work out the protocol between the head unit and the motor controller (uart at 9600) and used a ESP32 to man in the middle the protocol. Currently reverse engineering the meaning of the bytes in the packets sent between the units.

First attempt was taking apart the head unit and attaching a debugger to the exposed serial debug interface (Cortex M0) chip, but looks like the manufacturer had disabled flash reading by setting the flash security bit.

I just launched https://www.crowdwave.com a week ago, it spent 24 hours on the front page of HN.

Lots of people have visited but a launch on HN isn’t enough on its own. I’m trying to figure out how to get the word out to more people to kickstart it. The goal is for it to be a community that people return to as part of their daily online life. That’s not a programming problem so it’s hard (for me).

I've been working on https://wut.dev in my spare time. It's essentially a simpler, read-only, AWS dashboard where everything is a filterable, searchable, exportable-to-CSV table, with some extra features like multi-region mode, saved notes, and a debugger for access denied errors. It uses the AWS SDK for JavaScript, so everything is run client-side from your browser. I'm not 100% sure what direction I'm taking it yet…

are you designing the UI for every service by hand, or doing it programmatically somehow?

My primary project the past couple weeks has been applying the AI interpretability technique from Anthropic's famous paper this past summer (you know, the Golden Gate Claude one) to single-cell RNA-seq data. What works on one huge, inscrutible vector space ought to work on another, right? In either case, a fun way to keep in practice, both for comp bio and deep learning.

My side-project, in essence, the bash '&' operator for cases where the first process is already running. It took me months of searching before I could believe that this doesn't already exist, but there you go. I gave in to feature creep, of course, so it's a bit more than that now (I made a ncurses-based dashboard? Why??) but someday soon I'll make it public.

The few times I built TUIs with ncurses I wondered: why do I have to program so much by myself? ncurses is so basic, I didn't have too much fun building UIs with it (more than once). Is there a wrapper or a more modern alternative out there that provides containers and widgets like most GUI frameworks do?
