I had only a 5w bulb as with the 20w bulb the dc converter gets hot after some time.
I tried to add the bulb before the dc convertor but there is more than 12 volts and the bulb will not last.
This DC converter is max 3amp but I am very happy about it plus the price was very low. Nice device and I think that all people should have one, it helps a lot in any other builds where people are trying self looping.I has even load protection and thermal protection too.I have tried for a second a 50w bulb as load and it switched off imediately.

Got one just like that DC-DC conveter in a garage sale for 50 cents 
Hope all is well with the family and wife.  'Tis Saturday so you officially need to take the rest of the day off and get lots of rest.  We'll all still be here tomorrow
Thanks again for all you are contributing here!

@groundloop and our other EE wizzkids

I can't remember if this has been mentioned before

I have been searching around for the Hall effect sensors and have found the A3144uea has been discontinued.

One of the manufacturers suggests the A1120EUA-T as an alternative

would you agree this is what we need?

I was seeing some A3144 Hall sensors on eBay from Chinese sellers.  They usually ship world wide and good prices too.  Not sure on the quality.

7 X 0.125MM SOLDERABLE STRAND EN.Cu 500g

If the wire comes in 500g rolls anybody know how much we would need to make all the coils in the motor?
any ideas Please?

I believe I read somewhere Romerouk used 2 kg. of that wire so I guess 4 rolls of the 500 gram wire.
