===Biography===

I grew up in germany where every once in a while people would put their broken and unused household electronics on the streets for disposal. I picked up whatever I could, took it apart and tried to understand how it worked.

Line 13:

I am a full supporter of the right to repair movement and contribute through work, knowledge and helping others where I can.

==== Yamaha EBike Battery Dongle ====

====Yamaha EBike Battery Dongle====

Starting in 2016 I worked on an emulator module to use third-party lithium-ion batteries on Yamaha powered e-bikes. The module emulates the datastream of a healthy battery and sends it to the Yamaha PW series engine, allowing any power source in the 10-cell lithium-ion voltage range (27-42V) to be used in place of the original battery.

====Topping PA5 Amplifier D01 Replacement Module====

In 2023 I worked on a replacement module to help people repair their failed Topping PA5 Class-D Amplifiers, as documented in the audiosciencereview forums [https://www.audiosciencereview.com/forum/index.php?threads/topping-pa5-fix-d01-module-replacement-for-everyone.44219/#post-1572910].

==== GE Medical Flashpad Digital X-ray Detector ====

====GE Medical Flashpad Digital X-ray Detector====

I got hold of a GE Flashpad, a 2048x2048 digital radiography image sensor originally used in GE Optima 220AMX mobile X-ray units. These show up on the used market mostly in unknown or broken condition.

I tore it down, documented the hardware and spent time reverse engineering the URP/PDAP communication protocol it uses over ~~Gigabit~~ Ethernet. I got to the point where the detector can be fully identified over the network, scripts can be downloaded and executed, and a ~~complete dark~~ acquisition run can be driven from a custom host implementation without any GE software involved.
