i think for now it is in the spirit of DIYing something that is badminton related. as for whether this will end up being a blue print, it is hard to say. and if it does, it won't be for the faint hearted to work on. it will be quite involved. if it is something that end up functioning better than what is available and can be made at a reasonable price, it will be worth it for both the spirit of DIY and sharing. i guess we are just engineers at heart.
