what diameter do the magnets used have?
Would you perhaps have a link to where you bought them?

Thank you in advance and with kind regards,

Hi, nice design.

I'm just curious, is there a reason you made it belt driven instead of running directly off the motor?


yes, that makes a lot of sense :) experience - it will tell you ...

Шикарные разработки! Спасибо!

Благодарю за оценку :)

I love this design!! A few questions ...

Will a mason jar fit in this so it can be stirred without falling over? How long can you run this on full before the batteries die? How do you know the battery voltage and how long to charge it for?

Thank you! I can’t answer the first question, I don’t understand :) I’m not a native speaker of English :) The motor that I use consumes negligible, so it lasts for a long time. But I did not experiment. You can calculate by knowing the capacity of the batteries used and the motor consumption. I used the standard battery charge module. It has an indication of battery charging. And the body is slightly visible and everything is visible. The battery charge controller is designed for this function. it does not allow recharge and overdischarge of the battery. When charging is complete, the LED changes color.

Nice one! Can you tell me how slow it can go? I need sometring around 300 rpm. It can go that slow? Thanks!

You can twist very slowly. there is a motor controller pwm.
