Re: Trouble controlling brushless motor with ESC

Are those real panasonic cells? If so good buy, nice quality cells.. But not what you should use here, bldc motors are very power hungry under load, there are some special 18650 cells that are rated in double digit amperage but typically what you would use for a big bldc motor is a LiPo pack.

Re: Getting shock from micro hdmi port when connected to tv hdmi port

first thing that comes to mind is: do you walk much on carpets? can you replicate the shock by touching other things known to be earthed?

Re: How to Mask the IP address on my Pi for a webserver?

a VPN would hide your real IP, but for practical purposes your "fake" VPN IP isn't any less real than the normal one, only protects you from being geotracked. if you want people to be able to contact your website without having an IP to the pi that the website is stored on then I can only ...

Re: Best way to power a raspberry pi 3b+

that battery bank looks very suspect indeed, problem with most affordable USB powerbanks are only built to handle normal USB use which is nearly always under 2A. If your peak current surge won't be over 2A I think you can easily get away with a good quality 2A rated powerbank. For one of my battery ...
