This is my favorite place in Tokyo for electronic goods, ideas and products...
They hv this book with lots of ideas and electronics circuit diagrams.
Jap electronic students can designs circuit diagram ideas and put it in this book for free.
Companies will look at the book and if interested to use this idea will give % cut of profits to the designers, students or engineers.
If companies make 5 million products and the designers gets a cut in the profit...
Only in Japan, honor the trade deals is their key to success in their biz....
More better than open source started by US which dont make sense....
Angmoh hv a evil heart thats why lawyer economy do well and engineering industry fell over.
Japan no. 1....
