====''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/ ]<br>
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.<br>
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.<br>
====''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 ]<br>
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, <br>
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.<br>
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.<br>
Due to difficulties by the Product being sold and shipped from Overseas / Asia, in some countries warranty claims werent an viable option.<br>
