Great speed controller ! Do I have to change any component on the controller if I want to mount a 12V motor on my drill press ?
Thank you

Hi, thanks. The circuit can work well until 16V.

can you perhaps give me the individual part numbers of the DIY kit, as we are in South Africa and I cannot get the kit here unless I import it.
thank you,

Hi, I updated the summary with part list.

Thank you Naldin, much appreciated!

Bravo ! And the speed control is icing on the cake !

First, great use of the 555 and I always love to see the MultiSim, but onto my real question....

How s the runout of the spindle? I have purchased a few of these motor/chuck variants now and they always have horrible runout on the spindle. It seems that you have to step up to an er-11 to get something decent, but then its not small....

Yes! You alright. The runout of the spindle is very bad, but for my purpose it works well. Did you see the original project (link below)? Maybe that motor/drill fit for you.

is this motor better?

I think that the motor of the original project is better, I used this because I alread have it.
