That feeling when you turn an LED on in a really complicated way
Are there people out there building custom game controllers (like people build mechanical keyboards)?
Is there something like QMK but for HID gamepads?
Oi, fellow leftists, he's got a a point. #vote
The weird thing is that I haven't really seen many people direct wire the halves together. It's really only UART, I2C, or an IO expander. It's only really viable for a 40-45% keyboard, but so far it's working great. I haven't had interference issues so far.
Overhear view of the keyboard with the white 3d printed tenting risers set apart.
I've been experimenting with tenting, but I'm not sure if I'm all in. For long extended typing I think I prefer flat, but for regular coding work where it's not constant, the tenting feels really good
I also wrote my own firmware because I'm insane apparently. It's got everything I would have used in QMK: layers, tap-hold, combos, macros, WS2812 control for the status LEDs.
I didn't even use the tinyusb stack that comes with the pico SDK, so I got some practice debugging low level USB issues 😅
A 40% split mechanical keyboard. Both halves are black, symmetrical, with all black keys, except the F, J, and the two space bar keys which are white. None of the keys have symbols. The left half has an exposed raspberry Pi pico, where a USB C cable plugs in. The right half has a decorative feature where the pico would be. The two halves are connected with a decorative cable sheaved in patterned black and white paracord. Both sides are raised up on a small white platform to create an approximate 15° tenting angle.
This is my 3rd mechanical keyboard design. I went for a full split this time. It's 3D printed, including the low profile key caps. The switches are gazzew silent black. The halves are wired direct, with 10 pin IDC connectors carrying the rows and columns. No PCB either, the matrix is hand-wired.
A view of the fully assembled keyboard on a wooden table. A coiled USB C cable plugs into an exposed raspberry pi pico board which is mounted to the top plate of the keyboard. On either side of the pico sits 24 keys - a distance of about 3cm apart. The keycap set is grayscale, with the bottom row of keys all being white, and the next 3 becoming progressively darker in value. Under the pico there are 4 WS2812 LEDs used for status.
An in-progress view of the keyboard being built. The plate is shown upside down with all 48 keys pressed in. The keys are connected together in a hand-wired matrix, with the main backbone of the matrix being made of solid 1mm copper wire. The rows and columns are connected to exposed pins of the raspberry pi pico module with somewhat questionable soldering. The left side is done, while the right side is not yet complete. The RGB LEDs are not connected at all, and the leftmost one is missing entirely.
I've fallen down the rabbit hole of building keyboards lately. This is my take on a planck, with a pseudo-split.
Hand-wired with 48 keys, 4 RGB LEDs, runs QMK + Vial on a raspberry pi pico.
It only took me about a day to get used to it, which was a surprise considering it's my first ortholinear!
Very nice 👌
These are gorgeous Tom 😍
why was the boolean operation questioned by the police?
it was looking shifty
After just under 300 days, I've finally released a new video:

I didn't get one bit of it. Maybe not a good sign...
At first this joke seems funny, but then you realise there's real depth to it. It's got exponential range.
Hexagonal fractal constructed by drawing a circle, with 6 circles inside, and each circle gets 6 more circles inside, etc
A serpinsky triangle, constructed by recursively drawing a circle, with 3 circles inside with half the radius, with each circle getting 3 more, and so on.
Extremely stoked to be speaking at @hackadayofficial.bsky.social Europe in Berlin in a few weeks!
I'll be talking about writing motion control software for CNC type devices.
I think there are still a *few* tickets available. I'd love to see you there!
Mountains of wiggle room in that 0.89%!

Whenever someone in my family asks me to fix some broken device, 99% of the time it turns out to be a power cable failure immediately after the strain relief.
I know it won't happen, but I wish that Peter Jackson, Fran Walsh, and Philipa Boyens would be given a huge budget and free reign to make a proper Silmarillion trilogy.
A custom built pen plotter, sitting on a (somewhat) messy wooden desk. There is a sharpie pen in the modular pen holder. It appears to be drawing an interrupted circle. To the left of the machine is an organised chaos of wiring harnesses, going off to a couple of hand soldered boards, with an STM32 nucleo devboard at the heart. To the right, tweezers, a crimp tool, and a partial laptop can be seen.
I've got some exciting news to share soon!
I wouldn't go that far!
Electronics is a hobby where, in the beginning, you never have the thing you need to hand.
But then eventually, after spending perhaps thousands of Euros, and acquiring all kinds of components and equipment, you still don't have the thing you need to hand.
Totally. The thing is, i still have a day job where I make production stuff. That takes a whole different kind of thinking and approach, and you're rarely down in the nuts and bolts (even when it's firmware!)
Hey @hackadayofficial.bsky.social
If this is indeed the official account, it would be worth setting up a custom domain handle for bluesky. Seeing @hackaday.com would leave zero question about officialness
I've come to the realisation that, in my personal projects, I basically never want them to be "production-ready". Because I really want to get into the root, fundamental stuff, there is always going to be a well established thing that people should use instead.
I just want to know how it works.

My dude are you fucking serious? Most of the people I know have some kind of ASD, and their certainly not going around throwing heil hitlers
I made the mistake of peering over at twitter to see if people were talking about the Nazi salute.
They are, but it's all flat out denial. 99% of it is probably bots. What a shit show.
Do not dunk. Do not quote-post. Do not screenshot and repost.
They wish to be visibly cruel because it makes them feel big and strong.
