Repurposing an LED RF Remote to control anything! Nevell: After attaching a proper antenna as others have said, it also will help to tune the receiver by adjusting the brass slug in the small coil for best range. Most of the ones I've bought have been significantly off-frequency (typically 3-5MHz high. Also watch out for mis-assembled ones. They've screwed up the biasing of the first transistor, saturating it hard. Good receivers can achieve about -100dBm detection sensitivity or better. Bad ones barely make -80dBm. Nice video.

You have a 3 method to extend the 433 receiver first make 17 cm antenna one fourth of the wave length second use more powerful Arduino like uno connect with 12 volt the Arduino will convert it to 5 volt and connect the receiver with 5 volt from Arduino. Or you can adjust the screw on the receiver. this will give you the maximum ringe for the future projects

i was having the same problem with my ceil but could fix this by buying a 3 color led lamb which changes it, s color by turning it on / off and took it, s circuit and connect each stage with relay and hooked each relay with the light source I want. like that I could turn of/off any light or even both for around 10: ) hope this solution help

Hey GreatScott, did you try to build a transformerless 220-240VAC to 5VDC converter before? Using a transformer is making my creation too heavy. And, I do not really trust the Web when working with the mains. And no, I am not looking for a switching mode power supply.

Why would you go to all that trouble with hacking a reciever? an arduino can do this just fine by itself with just an infrared recieving diode. Edit aah it seems it is RF and not IR, then it makes more sense: -)

Hey just wanted to suggest u to make a video on the series and parallel connection of atx power supply from pc. For higher voltage and higher amperage respectively. It is my utmost request to please make one.

Hi, nice job. I didn't understand how did u wire up the SSR with switch to control the LED individually. Is it possible to turn ON using switch and turn off using RF remote. Thanks for the video.

Is it possible by using only one button for one Lamp?
Button 1 pushed one time = Lamp on
Button 1 pushed again = Lamp off
Would be cool, if you can make a video about it.

That is the worst receiver you can have like you witnessed in your video. If you need for any distance in your RF receiver you will need: 433MHz superheterodyne receiver

Hey! Make please 2. 1 amp i dont know how to so i need and you never make befor how to make 2. 1 you only make 2. 0 and if u create it, please make 2x5W+10W 8Ohm please!
