Hello. I am planing to build device for my hobby. Device is quite simple. I want to turn on/off light in 50-100 m range. I don't want to spend a lot of money for that. It will be used not very often. I was thinking to use these devices:

https://www.goodluckbuy.com/-button-wireless-rf-rolling-universal-on-off-remote-controller.html

Device mostly will be used in forests. Is it possible to do that with these items. I know that I will need power source, flashlight. What more I would need to buy? Maybe anyone can suggest better way to do that.
 
These look OK. YOu might also want to look at wireless doorbells too. These have a button that connects wirelessly to the sounder to save you drilling holes. But what you have pointed out might be cheaper. you will also need a JK flip flop to flip between the states (ON/OFF) with the press of the button
 
yes - although it is 20 years since I designed anything with discrete logic. I would normally put in a micro (PIC), but you should be able to find plenty of stuff on the net to do what you need
 

If you use one of the 74_ ttl series you will neeed a regulated 5V for the logic. If you use a CD series part, such as the CD4013B, you can use a voltage from about 4 up to 15volts.

And if i understand it right this thing has everything what i need

I couldn't find a link to a real datasheet, but the description looks good.
 
So, to sum up everything.

If i want to make this motor to turn on/off

n 50-100m range. I need these two items?

Also how to make remote and remote receiver to work together?
 

I am in the wrong business.

Look at the price comparison from one of the UKs largest suppliers. A simple Flip Flop. RS Components UK ship world wide.

9.1 UKPence is about 6c US. Compared to nearly $4.

RS will still be making a profit on these devices, so your goodluckbuy will be making a fortune in selling a few.

Utter rip off. Send the UK your business.
