==='''Brief Biography'''===
Every once in a while the city located in germany he lives in, had 1-2 days where people put their broken and unused household electronics on the streets to be picked up for disposal. He went there, picked up stuff, took it apart and tried to understand it. 
From taking stuff apart just to look how it works until actually fixing or reverse engineering it, years have passed by. He built himself a electronics workshop and gathered knowledge over the years from stuff he had on hand and/or access to. 
Learning by doing and from the broad spectrum of resources on the internet, he went into designing and manufacturing the things needed or wanted by himself and other people. A few projects that helped a handful of people are the result of this. 
He still lives in his hometown in germany as of today and is still tinkering, reparing, designing and trying to understand the rapid growth of technology. 
 
Full supporter of the right to repair movement by contributing work, knowledge and helping others as seen in the following Projects: 

====''Yamaha EBike Battery Dongle''====
Starting in 2016 gamerpaddy worked on a emulator module to be able to use third-party lithium-ion batteries on Yamaha powered e-bikes, his efforts and contributions can be found in the german e-bike and pedelec forums[https://www.pedelecforum.de/forum/index.php?threads/yamaha-reverse-engineering.39480/ ] 
This module allowed to use of third-party batteries or any power source within the voltage range of a 10-Cell Lithium-Ion Battery ( 27 - 42V ) to be used with the Yamaha PW series e-bike systems by emulating the datastream of a healthy Battery and sending it to the Engine. 
By this, most of the communication protocol was found out and people were able to extend their range by utilizing DIY batteries and repairing their failed batteries that made up 30 to 50% the cost of a new e-bike. 
This is just a brief summary, more information can be found on the Wiki page [https://wiki.recessim.com/view/Yamaha_EBike_Battery_Dongle Yamaha EBike Battery Dongle] 

====''Topping PA5 Module Fix''====
In 2023 he worked on a replacement module to help people repair their failed Topping PA5 Class-D Amplifiers as seen in the audiosciencereview forums [https://www.audiosciencereview.com/forum/index.php?threads/topping-pa5-fix-d01-module-replacement-for-everyone.44219/#post-1572910 ] 
The units in question had a fatal manufacturing flaw where they have used potting compound in their pre-amplifier module to protect it from being copied, 
but they overlooked the fact that it slightly expanded and contracted during thermal cycling and ended up cracking solder joins and rendering the module and with this the whole amplifiers faulty. 
The module has been depotted, reverse engineered, rebuilt with more efficient layout for cheaper manufacturing and successfully tested by a dozen of people. 
People all over the world have ordered, built and used this D01 Replacement Module for their Topping PA5 Amplifiers to get them back working and none of them have failed so far. 
Due to difficulties by the Product being sold and shipped from Overseas / Asia, in some countries warranty claims werent an viable option.

 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.
