That’s a NESty way to play games.
It’s a little bit more nuanced than that. Yes you’re denying ad revenue but it’s not a bad thing.

I save copies of the password database in several locations. I have to keep them synchronized manually but that’s preferable to using commercial ones that take turns in getting their data breached.
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 can’t get fooled again?
Really? Not more?
Edit. Oh I see, back then minimum wage was about $1.15. Lol. Yeah a 23x increase seems reasonable.

Good one. I haven´t considered that. The 7818 will only deliver current for very short bursts but perhaps that already is too much. I’ll look into the PWM solution.
That would require an H bridge with two Pmosfets on the high side indeed. And a way to prevent the gate voltage from going below -20V on those.
The PWM frequency on arduino nano is also a bit slow for controlling a motor so a 555 circuit needs to be added then. I have a large amount of XL4016 modules that work well though.
Thanks for the advice!
Well, the whole setup is a semi automatic greenhouse. It has a 12 channel peristaltic pump, grow lights, heater and a plant shaker for pollination. I’m attempting to grow indoor tomatoes and chili’s. Not weed although I have learned a lot from weed growers.
The system runs on a 24V power supply so that is easily accessible. The 18V comes from an LM7818 and the motor speed will be regulated with a buck converter module.
The off state is with both inputs at 0.
Between 4 and 8V. I’m driving a pump with a 12V rated 775 motor. Running it at full power makes the pump go too fast and with a lot of noise.
It’s kind of an overpowered motor for this project but I have a couple of spare ones.
