Hi, my name is Billbo!

My wife is a wheelchair user, mainly using a Invacare storm 4. I am trying to find a forum or site for people that modify's chairs to make them more user friendly. My wife travels a lot and one big inconvenience is having to carry the big battery charger with her which also counts on her weight allowance on planes. So I built one onto her chair completely weather proof, silent and she can charge on the train at meetings etc easily. I am now working on a phone charger for her chair. I am looking for a forum where I can talk out ideas. any suggestions?
