Normal: 4 days
Edited: 7 years
Boy, that escalated quickly.
ya hahahahaha id be fine with 4 days but this is why GreatScott is GreatScott
@@theengineer9910 Hmm I dunno, 4 days to change your tv remote batteries sucks immensely.
OMG how clever Is this dude. I thought I was pretty smart but this is many levels above my comprehension.
same here
I saw this module months ago, and now tons of people is uploading videos about it. it makes me happy
I have been searching for s good tutorial with the nrf2 for so long and the day has finally come.
My favorite part of this was where you showed how you increased the battery life/efficiency of your remote. I probably won't build an RF remote but learning about that was really useful. That's why I love these videos, you never know what you're going to learn.... Thanks!
One of my favorite tutorials yet. I bet your house is awesome with all these gadgets you build. Perhaps a tour video?
Amazing how fast you are producing high quality content!
I like that you are always very enthusiastic towards the end! ;)
This is one of those Great Scott videos that went over my head.
I love your projects like this m8. Keep up the awesome content:)
You are very creative man. Your projects are always awesome!
This video pops up right after i finished my IR controlled lamp with the help of your previous IR video!
Great content Scott :D
Thanks :-)
Another great project from the one and only Great Scott 🙏
even though i'm not planning making this I always watch just because I love your vids
Awesome stuff. That gave me an idea that I'd like to try. How about grabbing the signal to the IR diode. It would be fairly straight forward to write some arduino code which would translate all the key codes to RF signals. That way we could convert any standard IR remote into a full blown IR/RF remote (given it has enough space for the Arduino).
Sounds possible
I"m not an electrical engineer or electrician but in my opinion you design the most elegant and efficient circuits I've seen. You must have too many ideas to implement.
This is great! I hope you have future tutorials on low power mode. Thanks!
Hey great Scott please keep uploading thank you for uploading videos I like to watch thank you
Sehr Informatives Video aber die Formatierung deines Programms macht mich wahnsinnig :D
Very interesting project! Nrf24l01+s are easy to use and cheap RF modules. Still the bag of them that I bought some time ago is still gathering dust somewhere... Time to create something with them!
Thanks for this inspirational video!
Great video. Came here for advice on another rf project including a mini, which I got. But thats a cool project which is going on the ‘to do list’. Cheers
Great Scott you are awesome!!!
Rowyn Gaming official Yes you are awesome too!
Rowyn Gaming official and remember 1like = 1respect
I used this modules in my graduation project
, it's very awesome
You are the best! thank you for all the amazing content!!
How lovely. I just finished my RF project. It also had to do with turning on and off lights.
thank you :D I was looking for a tutorial to build something like that for a while ;)
You are simply brilliant, well done!
This is just pure genius, you are so clever!!!
Very cool. Nice tips on power reduction. 👍
Great idea, clear instructions, nice clear and concise video!
But I bet this project takes longer than 8 minutes to complete... lol
That's what I call hacked! Great job!
see! you!! NEXTTIME!!!
genius guy GREAT SCOTT!
I'm so glad I support you. This is an amazing hack.
Thanks
I am currently undertaking a project of making an rgb strip controller for my PC with an arduino and 3 mosfets. I'm using USB and serial commands in visual studio to make a programme to control it and it's going well so far. Love your videos
Great Scott: makes crazy stuff.
Me: gets exited about him having the exact same TV remote as mine.
Yay more HACKED!
Superb tutorial!btw: In transmiter module you should first put radio in sleep mode, then arduino.
What are you using for bus wire on your perf board? I found dollar store racket shaped bug zappers that have the perfect size wire. They are cheaper than going and buying a spool of the same wire.
you went from 4 days of battery life to seven years. ...that's amazing
Good work. Useful!
Hello, at 5:24 about the measurement of the current consumption(15 microAmp), Are you connect them in series (power supply to nRF24) and get it? Or need to take some step?
this video is awesome! I was curious if you could do an electronics basics on ftdi breakout programing
Extremely useful! I've had this idea before and now I know how to do it! One more thing I've been thinking of is how to control multiple strings of leds. You can use any remote so it's as easy as programming multiple inputs to one output like a different t.v. remote and buttons, for more than one room. So like this video says you can just code the remote outputs. Say there's a few rooms, so the "AUX on" code (master remote for tv, dvd, aux, and cable) with the kitchen t.v. turns on the kitchen lights only, however not the living room lights. The living room t.v. remote only turns on the living room lights, however the "TV on" code for the living room remote will turn on the kitchen lights (TV on for living room does not affect kitchen t.v.). My question is how would you control the different room leds? I was thinking a couple or multiple RF receivers and one power source. If it was just a big circle of leds and they had a way to turn on or off certain sections. So the kitchen receiver could control all the rooms lighting from one remote and the controller would power the entire string of leds, and at the same time, each individual remote can control each individual room of leds.
Hey Scott, I really enjoyed that video! Question: how many arduinos have you used in all of your videos combined (rund abute)? Have a nice day
You talk about power consumption and how you lowered it. Would it also have been possible to use an ATTiny or two as they use less power than an Arduino?
Scott, what do you know about MAVLink?
Please add it to the list of things to do, if you know anything / can demonstrate it
Nice video. What is the maximum range of the transmitter??
Thanks for your videos.
What about range of this project? *in building real life scenario
If I could I will put a 1000 like, very nice job, thank you
What kind of wire do you use on the backs of your PCB's that you solder to to make straight lines?
hi Great Scott its nice, Also we use bluetooth both the side to send the command ??
this project is amazing!!
Great video, as usual!
Nice as always. Thanks
You, my friend, are the Arnold Schwarzenegger of hardware mods! :D
Great job, man! So cool!
Is there some kind of kit that has a remote with a few receivers to wire up to things?
what's up Great Scott. I was wondering if you had any issues with the nrf boards because I've had these for a while and its always hard to get them to communicate. do you have any suggestions???
liked before watching
Sarvesh Verma a greatscott video is always good ;)
That's pretty gay mate
Same here. I just do it to videos that I know I'll like.
no one cares
Mateusz Bugaj Y u no cares?
what effect does this have on the remotes battery life ? did you have the arduino sleep the wake on a button press ?
Thanks ! I was looking for neat transmitter and receiver for my Arduino RC formula. I was using 433Mhz transmitter (because of antenas, that were on remote and formula) but I imediately ordered the 2 2.4G transmitters and ll upgrade it soon :)
+GreatScott! how far are these transmitters reliable for use?
That NRF24L can receive only another NRF24L signal only? or it can receive any 2.4Ghz signal from existing transmitter that not generated from NRF24L?
hey great scott will you make anther q&a&c video.
Hi! What's the range on these things (in an average flat)? Is it any good for home control? Wifi sure is a common oprion but also relatively power consuming one. BR!
Wow! Das ist einfach genial! Ich blicke zwar noch nicht komplett durch, aber das ist ein Projekt dem ich mich mal widmen werde :)
Was für eine Reichweite erzielst du ungefähr mit den nRF24L01+ ?
Is it possible to program the rf component with an access address? for example: if I have one transmitter and few recievers and I want to send data to specific reciever
Just an idea: How about hooking up the arduino to the IR led and analyze the signal?
Probably you could use any button (or button sequences) without ruining the remote control's circuit.
How do you know so much things about electricity..this is amazing
Why are you using 5V Arduino Pro Minis instead of their 3.3V counterparts?
Thank you dude!
could you have used an attiny instead of a full arduino for the
transmitter and receiver
What do you do with all those amputated voltage regulators?
When is the drone project going to be done? I am working on my own for a high school senior project and want to see what yours looks like. Mine is 3d printed with a red/black/clear style.
I don't know when it is done
Hi do you undertake private project work I have a three channel 433mhz transmitter but need it to control an IR receiver but dont know where to start I have the original IR transmitter as well any sugestions would be good and could pay for the work.
@GreatScott!
Hey, i love your videos and you got me started with electricity. ^^
Sadly im a newbe and need some more know-how..
May you recommend any good books, or a way, how to get deeper into the materia?
Your projects are a bit overkill for me at the moment, haha.
Cheers and keep it up! :)
great work
isn't it neccesary to install an inductor on the FM transcievers? How mach range can you get from those transcievers?
perfect job
great video! one question, what are the purposes of the diodes in series with the switches?
also, what are the implications of removing the voltage regulator?
The diodes were added to provide a single output from all of the switches without affecting their original purpose of providing 3 separate outputs. So now there are 4 outputs from 3 switches, one of which is when any switch is pressed.
Thinking about about an Air gun, which is controlled over an eleectroniv valve and an Arduino?
You are a genius!!
hi scott !greetings from argentina(an apologize for my english i hope you understand me ).So from the remote you only took the buttons,the signal that each one makes and the supply.. is that right? awesome job keep it this way I love what you do
You are a wizard!
What is the range of nrf24l01 inside a house. I find it's very less. If we walk with the transmitter there is package missing in between. And it seems it's fairly directional too. Any ways to improve this.
who said u should understand to like a video 😅
adam haklı amk
Wtf 5 years ago?
@@AliYassinToma uhhhh
what are the benefits of switches pulling to ground rather than pulling to vcc?
hey great scott can we use tv remote for rc remote car or something as a transmitter ??
Sure
scott, i have that kind of led controller, actually I have two but I think they have the same frequency that is why I cannot use them simultaneously, How can I Adjust the frequency so I can use them both.
because they can share on one remote. thanks
It's not clear to me why you added the diodes to the buttons for the low power mode, whatt i'm missing?
Hey, maybe you have worked with PADI ioT stamp ? How it is compared to ESP-12F ESP82666
Wich oscilloscope are you using ?
Thank you in advance
@GreatScott amazing work! Thank you for the time and attention you put in your videos.
I just have one question (maybe a stupid one), how can we know if we can just take out a voltage regulator like you did for the Arduino? Doesnt it provide a stable voltage source for the arduino? How can you know before hand?
I thank you in advance!
I know this is old but might be useful for someone: You have to check the datasheets of the parts, and of course know a bit about the circuits they belong to. In the case of the Arduino, it has an operating voltage window, not just a very specific voltage, as per datasheet, the controller itself on it (it's brains, the ATmega328p) can run with anything between 1.8 and 5.5v. That regulator likely keeps it inside the maximum operating voltage. Being the remote's battery voltage between ~3.3 and 2.2v when operating, it works well without the regulator. From the voltages provided vs. what it can handle, you already know beforehand that nothing should fry, but of course you should always test further.
Also from the 3 pin package, we can assume it's a linear type, so it would be wasting much power if it even had to work, compared to a switching type, so in case it was actually necessary, an upgrade in the power side would be very welcome to reduce power consumption as well.
You so cleaver bud keep it up/.,
Why the diodes are required for the interrupt? I can not figure it out...
I want to replace the ir receiver in my tv with an rf receiver. Is it possible to controle a tv with rf?
God i love your videos man :3!!!
Could you do some sort of GPS Tracker project? I asked a few months ago, not sure if you remembered.
I am currently working on something similar. But it will take a while though.
Or how about 12v car battery applications? I have been getting into the electrical systems of my car and adding switches for certain applications.
GreatScott! Hey. So does Xbox controller use RF signal. Sorry I am not pro on electrics. I see ur channel because I just love seeing chips and motherboards LOL 😂
All console wireless controllers use bluetooth due to their low power consumptions.
Good video.
5:02 that resistor is RED HOT or its just light?
