hello nul,
Now I did read all 118 pages,
and what I nowhere cant see is your replication,
I guess you spent not any cent, you bought even not sewing bobbins 
Are you just a supporter-talker
cheers,

PS:
Weekend again, what you doing in band, is it Bayan 
have nice jamboree

hi khabe

you read all 118 pages you say? and you haven't seen any evidence of my build?

it seems you've mislaid your glasses again, old friend!  would you like to borrow mine?

i guess when you read all 118 pages you didn't follow all the links which people provided, which point to additional information relevant to the thread

but amazingly, you are correct about ONE thing...

i didn't buy any sewing bobbins!


my band isn't playing now until June - i'm so old that i need at least a months rest between gigs

have a good weekend with your family

rock steady
np


[HINT: when you find the right link, my build details are on the page listed as "nul-point's corner"]

Hi Toranarod

thanks and happy  building

I hope this helps.

the MCP1407 MOSFET driver requires a stable Voltage. you could leave it out.   You could also use the Hall device recommended by Romerouk.

If you need any more help email or Post?

I know for a fact you do not need a very thick piece of Lexan to stop a flying object.  In the late 1960's probably about 68 or 69 a sales rep gave my company a few pieces to test.  We were going to use them as safety guards around machines so we could still see the machines and not worry about the guards getting broken.  The boss gave me a piece about 5" by 5" and about 1/4" inch thick and asked me if I had a good way to test it.  I took it home and sat it against the base of a large tree.  I then fired a shot at it from my 38 S&W pistol.  As I heard the slug whiz past my ear on the way back I realized I had done something very stupid.  There was a very tiny dimple in the Lexan where the slug had hit it and that was all the damage we could find.  Even 1/8" Lexan would probably be all we would need around our rotors as a precaution.
