HELLO, VERY GOOD JOB, ALL THE RESPECT FOR THIS

but u need understand something, u build this for fun and for u use or for possible sale ???? that u plan a productions of 9 oz weight machines, i reccomended to stop before loos e a lot of money, sorry
the idea of WIRELESS is great, absolutely, but become great when u can add to any machines already exist, cannot build a special machines wireless, don really have sense, like the WIRELESS COILS, at the end is not very good, heavy and people always love some other coils builders, hope u understand what i mean

the WIRELESS tecnology now still not suitable for TATTOO MACHINES, to heavy and complicate, maybe in 10 years gonna have a small battery and everything, for now still a good dream....

GREETS....
