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 :)

Also kudos to the great jokesters at Yamaha who named the marine diagnostic stuff “YDS” and then went ahead and launched a series of saxophones *also* named Yamaha YDS🤡

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.

Business idea: Amazon but with original products instead of counterfeit ones.

Pretty sure there’s a market there.

Dared to call German customs, was starting to describe my situation (nicely) and immediately got interrupted and yelled at. Wow.

Tracking of package stuck in customs since over 2 weeks

Tracking of package stuck in customs since over 2 weeks

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.

Looks like Garmin released an update causing a boot loop, how nice of them to celebrate the return of Pebble like that 😊

Unfortunately this is where the experimentation for today ends: I don’t have a >1000nm IR source at hand, and as you can see the silicon isn’t transparent at 940nm (at which IR remotes etc operate).

So waiting for new LEDs now!

For initial experimentation I designed a small adapter for the Raspberry Pi Camera Module v2 to mount to my Olympus microscope eyepiece.

You can find my model here: makerworld.com/models/1013817
