My name is Paul, aka MoJo. I started doing electronics as a hobby, with a focus on gaming. Now that I have several products available I thought it would be a good idea to create a brand for them, and thus Keiō Denshi Keikaku (京王電子計画) was born.
Why Keiō? I was finding it difficult to think of a good name, let alone one with an available domain name. I was browsing some Japanese sites when inspiration hit me. Keiō, pronounced 'kay-oh' as in 'Knock Out', is short and easy to remember in both English and Japanese. Even better, the domain ending .dk ('Denshi Keikaku' or 'Electronics Project' in English) was available.
