key-ripper VS hacker-scripts

Nice - a friend and I worked on my keyboard's debouncer and call it "eager debouncing", not sure if there's an official term for it. I agree that it's much better for latency.

Awhile ago I made an remote infrared sending tool so a raspberry pi can control my A/C unit

Since then I made a much slimmer, cheaper, more efficient version based on the ESP32 but I haven't written up much about that.

I also created my own keyboard with firmware in Rust

I've done a bunch of other small one-off projects too.

Good luck! I have an open source keyboard project in KiCad as well, feel free to reference or use anything from it.

Not sure if the author of the post is around, but I guess this is a question for anyone who has designed keyboards: have you ever tried using shift registers for reading all the keyswitch inputs, and is it worth it? Does it mean you don't have to use a diode per switch?

I've designed my own as well but just went with the traditional key matrix with a diode per switch. Works well enough for the current size.

I made my own keyboard layout just the way I want so I would put these caps on that, or replace the stock caps that came with my Filco board.

Twist looks awesome, I'd put it on my key-ripper

You can absolutely run Rust on the pico - I designed a keyboard with Rust firmware which runs on an RP2040. That being said, wireless functionality might not be existent yet in the Rust world for the Pico W, but I'm sure it won't take long to get added.

I looked at the schematic and it seems reasonable. I just completed an RP2040 project with USB C and it works correctly. You can see the project files here

Reminded me of Hacker Scripts, specifically `fucking-coffee`:

> this one waits exactly 17 seconds (!), then opens a telnet session to our coffee-machine (we had no frikin idea the coffee machine is on the network, runs linux and has a TCP socket up and running) and sends something like `sys brew`. Turns out this thing starts brewing a mid-sized half-caf latte and waits another 24 (!) seconds before pouring it into a cup. The timing is exactly how long it takes to walk to the machine from the dudes desk.

India has hundreds of millions of English speakers, is it a stellar IT nation? It can only boast a dozen puppet top execs of Indian origins in US megacorps like Microsoft and Google. And a few hundred thousands of office drones on H-1B visas. Half of them probably already got used as ass wipes and fired during the post-pandemic mass layoffs. Are there so many reasonably known Indian programmers? If the ones working in IT companies may not be known due to NDAs and code being proprietary, they should have as many known contributors to free software. Where are they? Do you know many? I know ONLY ONE. All India is known for are mean memes like the one about Kumar the proverbial asshole. You can read more about it here if you're not familiar https://github.com/NARKOZ/hacker-scripts

This story comes to mind. It could very well be made up, but someone else made those scripts inspired by the story.

kumar-asshole.sh

This is the script used to talk to the coffee machine:

I wonder how many other devices talk telnet and have a weak password. Would be cool to have a database of such models.

This reminded me of this internet folklore: https://www.jitbit.com/alexblog/249-now-thats-what-i-call-a-...

There is also a recreation of the scripts at https://github.com/NARKOZ/hacker-scripts

This is it, not sure if it's the original
