My secret to cooking? Even temperature control.

I cooked, it works, write-up and video in half a year...

Turns out Google is quite weird if you want to get working key rotation on your DIY tags...

But I think I'm onto something and just need a bit more testing to confirm.

it's this circuit: www.radiolocman.com/shem/schemat...
but much faster! delay is adjustable between 0 and 1 μs and the output pulse is 10 ns (available in both polarities)
a 12-bit DAC controls the delay, so the delay should be adjustable in steps of 250 ps

yep... 4 gigasamples per second with "6.5 digit" resolution... it took 33 minutes to capture 1.2 μs worth of waveform
(timebase not calibrated yet)

Don't have any Samsung devices to test it, besides the Samsung implementation is not very good to begin with 🥴

I have now abused Apple Find My and Google Find My (Hub?) (why are they names the same?).

Now I have a low power Bluetooth MCU, a debugger and some free time.

About to make a horrible polyglot tracker abomination.

Reminder to configure earlyOOM and or watchdog on your servers... In case some fuckass service decides to leak memory at GBytes per minute and lock up a remote machine with no kvm 💀

Well fuck

How much network bandwidth can I use before my ISP does something? Can I just saturate my uplink 24/7?

Meme image about installing STMicroelectronics STM32 software, showing the STM32CubeMX download page with instructions like "make sure you have administrator rights" and "chmod 777 SetupSTM32CubeMX", alongside STMicroelectronics, STM32CubeIDE, and STM32CubeMX logos. A cartoon character reacts with speech bubbles saying "ok ST" and "no ST", criticizing that this should not be the proper way to install the software.

Thank you ST.

age verification?

I used IR ports to send java apps and ringtones around.

shoutout to Coilcraft Inc. for their insane generosity in this age of corporate stinginess

Wanted to disable my rack cooling fans when the HDDs are spun down but I forgot about the toasty PSU that also needs cooling in there.

the reason the current source looks so small and weird is because I want to cheap out on shipping when I send this out for characterization

Is hashing every single metric I have in home assistant a good source of entropy?

So, uuugh starting a project to write my own paramedic CAD out of spite was certainly A use of free will.

Global warming is out of hand.

Got like 10 mosquito bites in mid December 💀

What it feels like to program an RP series MCU.

Dear dumb Realtek crab spirit, why are you waking my laptop back up the moment I close the lid?

Learning BGA reballing… and yes, all my balls exploded. 💀

A two panel comic as follows: - Panel 1: Presenter at the stage asks the crowd: "who want to buy expensive devboard", everyone in the audience raises their hand. - Panel 2: Presenter at the stage asks the crowd: "who want to install obscure toolchain", everyone in the audience lowers their hand.

Every single time

Pretty nice that they found a way to recycle the sacrificial layer from their CNC drills.

Intrigued by the IKEA hat 🧐

The design is very human.

Alt text: A vintage-style black-and-white illustration from Popular Science magazine (January 1963) shows a hand pouring oil into a hole in the ground. The original text suggests disposing of oil by digging a hole with a posthole digger and covering it with soil. However, the image has been edited with colorful 18650 lithium-ion battery cells placed into the hole. The caption reads: "Disposing of used 18650 cells can be a problem. Solution: Dig a hole in the ground with a posthole digger. Then pour the 18650. It will be absorbed before your next change. Cover the spot with soil."

Texas Instruments has some much cheaper and also pretty good switching chips. I think they're all grouped under the TPS series.
