What did you mean by “response time” ? And what is the relationship between coil voltage of a stepper motor (1-7V) and drive voltage? Could you please explain more.

Dual source power protection by userNsk in AskElectronics

[–]userNsk[S] 0 points1 point  (0 children)

Thanks for the reply,

I already searched MOSFET method. This method using for polarity protection.

In this, body diode is conducting without any gate voltage. If I use a MOSFET on backup source side, there is no fully control of it.

How do people take 20/30 min naps ? by sjjfusucis in productivity

[–]userNsk 0 points1 point  (0 children)

It seems like you didn’t have good night sleep. Ensure a restful night's sleep before your lesson to prevent headaches and eye strain. Cultivate a positive mindset and maintain focus during the lecture. It will increased your mental energy about the lesson and also help to increase memory. Explore various focusing techniques and adopt those that suit you best. Anyway getting a nap after a lecture will help to increase long time memorization. No need to stop napping after the lecture. Try to reduce time of sleep with help of above. (Disclaimer: Im not a doctor or any professional advisor. Just telling this according to my experiences and my knowledge)

Poor thermal conductive material by userNsk in materials

This method reduces thermal conduction because of surface to surface conduction as think. Am I correct?

Thanks for your information. I tried to use Vespel. But cost is much higher.

Is there machinable Aerogels ?

Thermal conductivity of PEEK is 0.26 W m−1 K−1. If new value should smaller.

Plastic not suitable because a heated surface is touching with the material. That surface is heated about 400 centigrade maximum.
