Hi Tommy,
Interesting device. Have moved this to "accessibility off the web" as not related to web accessibility. Hope you get some useful feedback.

love it.
any invention needs a business plan so even if it is the most exciting thing in the world it is no use unless a lot of people need one and are able to buy.
for instance a mouse trap costing $40 wont sell un less there is $39 costing to sell it.
i do a lot of inventing usefull to me but probably too expensive to make for some one else to afford.

It's really a wonderful machine. I'm really appreciate your filial. It must cost many energy and time for you. Is that machine expensive?
