Oops I haven't done an ! I am an electronics/firmware/open source nerd who lives on Djaara Country (Central Victoria, Australia).

Professionally I'm starting to spin up a one-person embedded systems business, redyak.com.au

Personally I'm trying to contribute in small ways in my community, and very slowly building an Electric Vehicle conversion in my shed.

Wild stories in this Oxide and Friends episode reminiscing about the first dot com bust share.transistor.fm/s/24fc5695

I knew it was frothy, but guess I was isolated from the details by being Australian and only just in university. By the time I graduated things had already moved on to the next nonsense...

Code isn’t readable if you need to use your eyebrows:
🤨 Confused!
😳 Surprised!
Keep working on it until it’s easy to read: 🥳 😍

Calculation of π, from rain falling on two wooden plate sensors, one circular and one square: the number of raindrops that landed on each plate during a storm was counted with an Arduino and π was calculated as the ratio [source & credits: buff.ly/2Dqy0gN]

> after he was elected President of the Institute of Radio Engineers. In his inaugural address, de Forest lashed out against what he called "the insistent ballyhoo of sales talk [on radio], which now viciously interrupts 70% of entertainment programs." He predicted this would soon lead to a large loss of listeners and huge decline in ad revenues. He urged the engineers to regain control of their creation from the "manufacturers and outside businessmen" who had taken it away from them.

@aparrish at this point I'm just not sure anything good comes from starting with the tech instead of starting with the human needs and relationships. reverse engineering is often seen as like a power move, something you can do to get control back. it's not a cheat code though, it's just obeying the same rules power always follows.

when the creator of octocat adventures* speaks, you listen. David Oreilly is dead on.

Someone on 🦞 wrote “The sooner we stop romanticizing open source development, the better for everyone” and it made me wanna uninstall my compiler, format my entire disk, get a library card or something. Or go grab the copy of Ecclesiastes from my own shelf.

Last part of my series on reverse engineering BMW electronic gear selectors is up: projectgus.com/2022/07/bmw-f-s

Watch me mess about with the bespoke transmission emulator software "Bavariatron 5000"!

I'm generally all for this Kate Bush revival we're having, apart from getting Running Up That Hill stuck in my head for 24-48 hours every time I see her name mentioned

The mind-blowing reason CDs use a 44.1kHz sample rate 

It's because early digital audio was recorded on videotape at 3 samples per line. 245 lines per field in NTSC, 294 in PAL. 245x60x3 = 245x60x3 = 44100.

Part two of my BMW gear selector reverse engineering odyssey is up - watch me figure out how to turn on an expensive German LED! projectgus.com/2022/06/bmw-f-s

Electronics folks, if the conformal coating flakes off the top of a chip like this then could it be a sign the chip has gotten hot, or more likely just an assembly/curing issue? Rest of the board has A+ coating

Plus now I have conductive Blu-Tac residue to clean out of my breadboard

Me, debugging a module in a breadboard: "Why are breadboards always so flaky... fed up with this, I should know better... time to get the module out and wire it up without the breadboard." ... "Oh."
