Pardon my shitposting.

Thriving in the gap between software and hardware.

A fucking flower.

Ever heard of the game Shenzhen I/O? That WAS my day job.

gaudat··on I built an app to backup Live Photos from iPhone to external hard drives
>home NAS setups aren't realistic for most users

Citation needed. Get a Synology NAS and use their Photos app which backups Live photos on both iDevices and Androids. Buy it for life.

gaudat··on Watch Antimatter Fall: Scientists Capture Gravity's Pull with a 3840MP Camera
It's very likely that PCB is made in KiCAD seeing the fonts. I really really hope they make the project files available. That would be a sick example project.

Also, obligatory ꙮ

gaudat··on AEgIS turns phone sensors into antimatter camera of unprecedented resolution
I dig that PCB design. The panopticon (?) artwork and how the decoupling caps are lined up perfectly along the circumference.
gaudat··on This New Algorithm for Sorting Books or Files Is Close to Perfection
This post links to Quanta [https://www.quantamagazine.org/new-book-sorting-algorithm-al...], which links to the actual paper [https://arxiv.org/abs/2405.00807].

Tbh I was expecting a supercharged Dewey Decimals...

Imagine that thing painted neon green and hurling down the highway.
gaudat··on Hakko solder wick cutter [pdf]
For someone who has dabbled in electronics my first impression is "this is useless". Soldor wick is basically multi-stranded copper wires. You can already cut it with whatever snips you have on your bench.

But Hakko is Japanese i think? They like to release wild products. I remember Makita releasing a microwave oven and coffee maker that uses their battery and has their color scheme.

gaudat··on Sitina1 Open-Source Camera
The design is pretty modern. But what is with the choice of the Kodak CCD sensor? CCD cameras got a resurgence in Chinese communities with second-hand camera prices increased like tenfold.

Also see Apertus Axiom where they also used the Zynq but used one hell of a CMOS sensor that can do 4K 300FPS.

gaudat··on House committee approves bill requiring new cars to have AM radio
A part of me really wants to push this and see how far it would go. Why stop at AM? Add in shortwave radio and let us listen to stations on the other side of the earth.
gaudat··on Ask HN: Marketplaces for Embedded/FPGA Developers
Do you need latency measured in nanoseconds or multiplexing hundreds of sensors? Otherwise it makes a lot more sense to use a Cortex-M or Cortex-A.
gaudat··on What Is Rotoscope Animation? The Process Explained (2020)
For your second example it's impossible to find a YouTube video of Chika dance that is available in every country. Try this: https://streamable.com/0hrdh

It's remarkable how smooth the animation is. And how natural the character's movements are. This scene jumps over the uncanny valley straight into being enjoyable.

And I think there's an AI paper from a Chinese researcher using this video as a demo.

Wenext. I used it from single quantities up to a couple hundred pieces. They assign a human in the loop to check your model that you can email to.
gaudat··on The Rubik's Cube Turns 50
Hard to believe it's only 50 years old because of how mechanical and simple the cube is compared to other gadgets of that time.

I remember 15 years ago finding many variants of cube with different sizes and number of dimensions (yes, there is a video game of a 4D or 5D rubiks cube).

gaudat··on The unbearable sorrow of Apple Weather
Hate to say that but it works for me. I am using the largest regular* font size on an iPhone SE and there's no issue on the exact same page in the weather app.

Perhaps OP is using one of the extra-large font sizes hidden behind the "Larger Accessibility Sizes" toggle. It can be expected users at that font size value accessibility over aesthetics. As screen space is limited there is of course a point where things start to look broken.

The weather app could include a TV or clock-like layout for extra-large text sizes but that doesn't really fly with Apple's UI/UX consistency.

gaudat··on STM32 MCU family goes 64-bit with the STM32MP2x (Cortex-A35)
And the line between the two is blurred now with MCU running at hundreds of MHz. The STM32H7 is has more IPC than the original Raspberry Pi.
gaudat··on STM32 MCU family goes 64-bit with the STM32MP2x (Cortex-A35)
It all comes down to cost. These BGA chips have pins under the device unlike older packages like QFP or DIP. The pattern of missing pins is designed so it a fewer signal layers to bring out all the sigal connections in a typical PCB process. Devices with full grids would need more layers or tighter tolerances.

The appeal of STM32MP1 is you can put DDR momery with the chip on a 4 layer board. ST even provides the layout.

gaudat··on The C bounded model checker: criminally underused
I miss this kind of stuff in computer programming languages.

In hardware design, verification is done simultaneously with design, and semiconductor companies would be bankrupt if they did not verify the hell out of their designs before committing millions in manufacturing these chips.

Even among hobbyists this is getting traction with yosys.perhaps its time for programmers to adapt this kind of tooling so there will be less buggy software released...

gaudat··on NASA unlocks $1B canister of asteroid dust
Mildly interesting: I opened the titular image in a new tab hoping to find a higher resolution one, only to see that NASA.gov is using Wordpress, and the original image file is a whopping 102 megapixels, with all EXIF info intact, taken by a Fujifilm GFX100s. A suiting tool to take a photo of an object worth $1B.

FT2232H with libMPSSE. It is even advertised as a USB-to-JTAG chip.
gaudat··on Memory leak proof every C program
Next thing they do is to optimize the hell out of kernel process management things until it catches up with the overhead of calling a function in a GC language.
gaudat··on "432 Hz tuned music can decrease heart rate more than 440 Hz tuned music"
Nightcore lmao.

The other question will be, can music tuned to a higher A frequency increase heart rate and make a good pre-workout?

gaudat··on 10 Second Teleportation
Same thing happened with my work computer in the office network with a MITM HTTPS firewall. The IP address jumps between the coasts randomly confusing the Windows weather widget. Images failing to load on a lot of websites because the IP address change triggers something in their CDN. Everything is working fine when I'm WFHing so it has to be the office network.

Oh and this can also happen when a mobile user is jumping off their home wifi network to a internationally roaming data card. Why they would do that? Because data is cheaper this way, or they are actually tourists. So please do not block users just because they are doing this teleportation dance.

gaudat··on High-speed 10Gbps full-mesh network based on USB4 for just $47.98
USB4/thunderbolt is a magical protocol. Turns out the fastest way to move data between 2 modern PCs is to connect their thunderbolt ports with a USB-C cable. The connection shows up as a ethernet port on Windows and I can easily saturate a SSD with its 1GB/s+ transfer rate. And it just works (tm). Reminds me of firewire on these 20 yo Macs.

And What happen if you wire both ports together on the same PC?.. Do you get a broadcast (thunder) storm?

I thought these crystals are 3D printed at first judging by the layered look.
gaudat··on Deep-TEMPEST: Recovering images from unintentional EM radiation of HDMI
I imagine using HDCP or DPCP would defeat this since encrypted data should look pretty much the same as noise. There is finally a use of these technologies beyond DRM.
