Very good 👍

Alternative shed cooling method....hydronic cooling.

Im trying to set up some water pumps to this relay. My question is I know the positive for the the pump will go into the center of that relay. The ground for my pump, do I ground it back to my DC power supply? If I want 2 of the relay to turn on 2 pumps at the same time, what is it that I need to watch out for? Will the DC power supply, supply enough power to both pumps?

hey and thank for th vedio I want to ask you where can I find (off delay timer 12v in the market) the counter start to count when I cut the power? I mean i want it delay off..12 volt with relay when i press power the light turn on and it countinus lighting until I cut power off then the light turn off after 5second

Great video. Cheers from the US.

On and off

I'm in a small cargo van that has two large fans (one inbound in the front and another the outbound in the back). Ventilation is great and it very small space (like <100 sqft).. In the middle of the Florida summer it's 80F+ at night . I don't sweat, but it's not entirely comfortable either. I've noticed there is huge difference when it's just 5F lower outside which it typically is October - May, but June-Sept can be tough. I tested swamp bucket coolers and they actually help but not so much with all my ventilation and just a pain to keep fetching ice. I'm only concerned with cooling the van just a little bit and at night, there is no lounging in a van in the day time in Florida. I was wondering if a few strategically placed Thermoelectric Peltier Modules where the van draws air might do the trick? Any way I could use the van's metal roof skin as the heat sink? Is a fan to dissipate even necessary? Think a modest 5 degree drop at night is possible (80F to 75F) in humid Florida? I've been thinking of even testing placing a bag of fresh ice on top of solar panel the inbound fan would be pulling air off but not sure how cold conductive the plastic structure of a solar panel would be. Some testing on my channel.

Hi. Great video! Can you tell me if you can change the frequency of two receivers to be controlled by one remote?

Could i use this for light of motorcycle? Or can i use 12v to on each relay? Thank you.

Sir can I used it to close car window for 4 seconds which requires 20 amps?

that's all good but showing full circuit diagram would help me out im making kayak live well can you Email me the full circuit diagram please …………..peternohlmans@bigpond.com ……………..

Very nice.but showing full circuit diagram sir.

With the red relay can you set it up where an led instantly comes on for ten seconds and then shut off instead of being delayed so many seconds

Hello,I'm looking for a compact device like this to power accessories on a motorcycle,could a module with say four relays do the job,I must add that I know nothing about electronics.many thanks
