I only tip when on vacation in countries like Vietnam. Since a few euros is a lot of money there.

Anywhere else not.

I think it doesn't matter too much. Suboptimal energy storage is still much better than none.

Tell me it's an Onion article.

Watch Lord of the Rings on a phone mounted on the steering wheel. I called the police immediately.

Thanks again for the advice. I made a working prototype and attached it to my pump. The PCB is also made at home which is something I'm trying to learn.

For now I've used just optocouplers to drive the mosfets, since pulling p-type gates down to above -24V seemed like a hassle. I've ordered some IR2210 gate drivers and intend to use those with PWM later to not have to use a buck converter.

Here's a video of the pump. https://drive.google.com/file/d/1qKDBLTbYi2Fbu3UOXpxqSoj00oueWK-K/view?usp=sharing

And the pump in action. https://drive.google.com/file/d/1--HyeJGtYS5dgsjgelE6CrOm2vbBmwXU/view?usp=sharing This version has a stepper motor instead of a DC motor. Stepper motors have low speed limit which is why I'm trying to change it to DC motors.

You work with Colin Robinson?

You can't get fooled again?

What's so bad about AMD? They seem a lot better than Intel imo.

Netherlands too. I've learned to avoid such places.

Really? Not more?

Edit. Oh I see, back then minimum wage was about $1.15. Lol. Yeah a 23x increase seems reasonable.

 

I'm interested in learning how to make a proper PCB rather than perf board with wires all over the place.
