JanaI love discovering personal blogs and websites.
No algorithm.
No competing anything.
Just a person, putting out what they want.
It's beautiful.
After hours of debugging I figured out that I accidentally ordered GD32F350R8T6 instead of GD32F350RBT6, with the latter having twice as much flash memory. Explains why the firmware doesn't fit.
Baklava MonsterReview of a failed vulnerability disclosure process:
"The whole point of VDP, security.txt, bug bounty, etc., is to make the process of reporting vulnerabilities as smooth as possible and the main focus should remain on removing roadblocks for legitimate reports."

Atc1441DOOM on the ANKER Prime Charging station😅
The internal SWM34S MCU is just way too nice!
8MB RAM + 16MB Flash directly mapped to memory goes brrrr

Custom firmware on an Heat cost Allocator...
No use but funny to look into it and its WMBUS RF Packets
Next step is to dump the stock firmware via the ages old Timing attack from @travisgoodspeed (MSP430F417)
Some people have asked and I saw some demand in my logs, so I added an RSS feed to my blog (https://stefan-gloor.ch)

Let me know if there are any problems!
