Could handcrafting hi-fi put food on your table?

Thanks for all suggestions! BoomCase has some great stuff.

Those are battery-operated devices, no a/c required.

JCX: the case is made of heat shrink tube around copper rod frame. It's easy to apply and gives nice soft feel to end product. Problem is it's too thin and several layers are needed. I want to try some office supplies next for augmentation, maybe wood planks.

It's probably possible, but not entirely legally. If the product has anything digital, technically you'll need FCC testing. You probably can't afford UL (or CE if you want to sell overseas). You certainly can't afford liability insurance, so you better hope nobody sues you. You probably couldn't even afford to mount a defense. If you have no assets, go for it- people with no assets and no insurance don't get sued. IMO, if a product had moderate low volume, you might make a buck selling it, but the time required to hand build things on a one-off basis, given what they could possible sell for, will have you making about $1 per hour on a good day. I hate to be this pessimistic, but the day of making good in a garage shop (like HP, Apple and many others) is probably over. Keep an enjoyable hobby enjoyable and a hobby.
