We've extended the RP2350 side-channel hacking challenge to April 30 - and even better: To make attacks for the challenge easier, we decided to disable the random chaffing and some more mitigations!

Call for flash-chips at DEF CON!
If you have leftover or rare SPI flash-chips that I can have for testing some tooling I’m building I’d be very thankful.
Also if you have devices where you had trouble dumping in-system I’d love to give it a try. I’ll be at Embedded Systems Village :)

Does someone know whether it's possible to get recorded traces from a Rigol DHO800/900 using SCPI?

Wow modern cars suck.
A relay is not opening/closing reliably.
The relay is epoxied into a PCB assembly.
Replacement cost for the 5EUR (being generous here) relay is 400EUR because you can only buy the entire assembly.

Dared to call German customs, was starting to describe my situation (nicely) and immediately got interrupted and yelled at. Wow.
The German customs system is so hopelessly broken...
It's faster to send something from the UK to Finland, import it there, and then forward it to Germany than trying to import something from the UK to Germany directly.
