@porkbun.com What the hell is this list of administrative divisions for Ukraine you got? Why is Donetsk and Luhansk oblasts are missing, despite being internationally recognized Ukrainian territories? Did putin and orban write these?

oscillators don't, but amplifiers always seem to 😖

Time to revive my SoM project. This is such an idiotic way to shoot yourself in the foot it's insane. Perfectly reasonable alternatives exist, but they decided to be HP...

Raspberry Pi is locking down RAM upgrades in firmware: www.youtube.com/watch?v=ltof...

anyone see the problem here?

Maker Faire Hannover Post 2: @dmytroengineering.com helped me unbrick an MSO-X 3034A! NAND flash corruption is a known issue and repairs are well-documented, but we came up with a method that uses ethernet to load the flash, plus this gives us an opportunity to bypass future NAND degradation!

They can if you think about the architecture of the underlying computer a bit harder 🧌

I love the RP2 but unfortunately even they can't do certain things

just like the render (jumped the gun on the inductances)

ThinkPad durability test

bodges are inevitable 😖

I had a vision

E-ink is so cool

Waiter! Waiter! There is an 8051 in my 10Gbit Ethernet SFP+ module!

Least over engineered pointing device

attoamperes?

today I'm testing the dielectric absorption test stand

Forgot to post the rack update www.printables.com/model/170182...

I just realized that my new signal generator has adjustable rise and fall times, so here's a demonstration of I/C = dV/dt using a 10 nF / 1 kΩ highpass filter

RIP Marvell 10Gbit NIC... At least you gave us the ball pinout in return for your sacrifice... Another sacrificial 10Gbit card (Realtek this time) has been ordered, why can't they just make the datasheet public smh...

the HMC8043 completes my all-LAN all-SCPI setup! to celebrate, I wrote a script that loads a few useful voltage/current configurations without having to fiddle with the front panel controls

I wonder how much current I can draw from the 3.3V standby supply on the power button of my laptop...

How does that even happen?

okay so now I have like a very expensive clock

JFETs are underrated

Just connecting a client with a 10Gbit NIC to my router's 10Gbit Ethernet interface causes the average power draw of the entire rack to jump up by 3-4W. Not even routing traffic, just having a 10Gbit link in general.

My secret to cooking? Even temperature control.

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)

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 💀
