Self-Contained Talk 'n Action Percy

I love Cody Traverse (Aga Gai Nogai, アガ・ガイ・ノガイ) found a way to make this Talk 'n Action Percy run without the mail coach; including sound, the track sensor, everything. They did this by rearranging the speaker and PCB to make room for a small battery pack of an unspecified cell type. The first version (not pictured) somehow used bigger cell/s but ran slower, and another try used a coin cell that unfortunately exploded. The pack in these photos may have been made of N batteries. Demo of latest version

Sadly, he only lasted two months. The way it was done proved too much for the PCB, and it eventually overheated. However, they did buy a TnA Thomas and plan to do the same mod with him. Here's hoping they'll find a more harmless power method so it won't happen again.
