HACKED!: TV Remote becomes an RF Remote || nRF24L01+

[@estebanzd9434]

Normal: 4 days Edited: 7 years Boy, that escalated quickly.

[@theengineer9910]

ya hahahahaha id be fine with 4 days but this is why GreatScott is GreatScott

[@mrkiky]

@@theengineer9910 Hmm I dunno, 4 days to change your tv remote batteries sucks immensely.

[@UntrackedEndorphins]

I saw this module months ago, and now tons of people is uploading videos about it. it makes me happy

[@eriknakamura]

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!

[@AnimalFacts]

One of my favorite tutorials yet. I bet your house is awesome with all these gadgets you build. Perhaps a tour video?

[@JustAnotherThisDJ]

OMG how clever Is this dude. I thought I was pretty smart but this is many levels above my comprehension.

[@htkevo5273]

same here

[@ElGatoLoco698]

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.

[@kiaelfenheimret4397]

I have been searching for s good tutorial with the nrf2 for so long and the day has finally come.

[@NiceEyeballs]

This is one of those Great Scott videos that went over my head.

[@NorbertHarrer]

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).

[@greatscottlab]

Sounds possible

[@BoomBrush]

Could you do some sort of GPS Tracker project? I asked a few months ago, not sure if you remembered.

[@greatscottlab]

I am currently working on something similar. But it will take a while though.

[@firebird95driver]

Or how about 12v car battery applications? I have been getting into the electrical systems of my car and adding switches for certain applications.

[@beedslolkuntus2070]

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 😂

[@russel96]

All console wireless controllers use bluetooth due to their low power consumptions.

[@chrisgreece52]

This video pops up right after i finished my IR controlled lamp with the help of your previous IR video! Great content Scott :D

[@greatscottlab]

Thanks :-)

[@wi_zeus6798]

I like that you are always very enthusiastic towards the end! ;)

[@cessnachannel4285]

Great Scott you are awesome!!!

[@cessnachannel4285]

Rowyn Gaming official Yes you are awesome too!

[@cessnachannel4285]

[@jollyreal1]

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?

[@boris5448]

even though i'm not planning making this I always watch just because I love your vids

[@PhilippeFrancais85]

no mention of silver-copper wire :(

[@rohitdatar3988]

I was thinking the same xD

[@slawor4]

PhilippeFrancais85 silver-cuuper wire

[@MarianKeller]

To anyone wondering what the diodes on the switches are for, they form an OR-Gate to pull down the single interrupt pin whenever one or more switches are pressed. Without the diodes, you'd just short all the switches together.

[@olim8000]

great video! one question, what are the purposes of the diodes in series with the switches?

[@reLi70]

also, what are the implications of removing the voltage regulator?

[@twotone3070]

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.

[@Hugatry]

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!

[@vsmk8747]

you went from 4 days of battery life to seven years. ...that's amazing

[@nadirkhan9423]

hey great scott can we use tv remote for rc remote car or something as a transmitter ??

[@greatscottlab]

Sure

[@marhar2]

This is great! I hope you have future tutorials on low power mode. Thanks!

[@LazerLord10]

Wow, I'm planning on using a pair of these exact RF transceivers for a DIY electric skateboard. Hopefully it works.

[@greatscottlab]

In theory they should work just fine for such an application.

[@hugogalciusphysics]

You are very creative man. Your projects are always awesome!

[@sreeprakashneelakantan5051]

Another great project from the one and only Great Scott 🙏

[@KrishnaKumar-lw6oz]

Great Scott: makes crazy stuff. Me: gets exited about him having the exact same TV remote as mine.

[@MrJob91]

Amazing how fast you are producing high quality content!

[@FindLiberty]

Great idea, clear instructions, nice clear and concise video! But I bet this project takes longer than 8 minutes to complete... lol

[@tobywenman4769]

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

[@Flowxing]

Sehr Informatives Video aber die Formatierung deines Programms macht mich wahnsinnig :D

[@Victoare]

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.

[@harshchaturvedi4218]

5:02 that resistor is RED HOT or its just light?

[@Ilikeridin]

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

[@deldarel]

How lovely. I just finished my RF project. It also had to do with turning on and off lights.

[@jchrzaniuk]

Superb tutorial!btw: In transmiter module you should first put radio in sleep mode, then arduino.

[@thetommantom]

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.

[@T42nk]

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?

[@Od3o_ela_sabil_rabek]

I used this modules in my graduation project , it's very awesome

[@Mr.Unacceptable]

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.

[@ToroMoto]

I love your projects like this m8. Keep up the awesome content:)

[@dylanbenzi9901]

Is there some kind of kit that has a remote with a few receivers to wire up to things?

[@knoah-hc4xo]

Hey great Scott please keep uploading thank you for uploading videos I like to watch thank you

[@maheshbhat8714]

Nice video. What is the maximum range of the transmitter??

[@mehmetedex]

People with higher IQ tends to accomplish a task in a more complex way. But that doesn't mean its the best choice. I rather could have done this by using nano as real time logic analyzer by connecting to IR-LED and sending the resulting byte code over NRF thus in this way all buttons will be functional and you dont have to damage IR side also the remote controller so we could have both available always. Thanks for the effort keep up the good work mate.

[@joepool2003]

This is just pure genius, you are so clever!!!

[@TomRoot]

Yay more HACKED!

[@RahulKumar-zs2wv]

hi Great Scott its nice, Also we use bluetooth both the side to send the command ??

[@NetisAmarok]

That's what I call hacked! Great job!

[@godissogoodtome]

What kind of wire do you use on the backs of your PCB's that you solder to to make straight lines?

[@moechano]

Scott, what do you know about MAVLink? Please add it to the list of things to do, if you know anything / can demonstrate it

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.

[@greatscottlab]

I don't know when it is done

[@jimsmindonline]

Very cool. Nice tips on power reduction. 👍

[@tomgarside480]

what effect does this have on the remotes battery life ? did you have the arduino sleep the wake on a button press ?

[@khutjomaputla10]

could you have used an attiny instead of a full arduino for the transmitter and receiver

[@myildirim]

can you add the voltage rating of the capacitator we use ? It says 47uf but i could not get what volt is it, (is it 5v?). :(

[@tonymasse3887]

Also, I'm confused about the 47uF, as the official Doc from Nordic invites to use a 4.7uF: "Mounting a large surface mount capacitor (for example, 4.7µF ceramic) in parallel with the smaller value capacitors is recommended." I personally had initially put a 1F (5v) which I had at hand for my tests, as if you put none it just doesn't work. So I'll try with a 47uF (in 5v) next.

[@codybattery8370]

+GreatScott! how far are these transmitters reliable for use?

[@woalidhossain9487]

Is it only me who does not understand a single thing about circuits but still watch every video?

What do you do with all those amputated voltage regulators?

[@miguelberbegal9461]

isn't it neccesary to install an inductor on the FM transcievers? How mach range can you get from those transcievers?

see! you!! NEXTTIME!!! genius guy GREAT SCOTT!

[@יוסיבןעזרא-צ1ד]

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

[@salutoitoi]

Wich oscilloscope are you using ? Thank you in advance

[@raphaelowobi2736]

You are simply brilliant, well done!

[@johnny4498]

Thinking about about an Air gun, which is controlled over an eleectroniv valve and an Arduino?

[@balintradocz]

Why the diodes are required for the interrupt? I can not figure it out...

[@thafimulislam542]

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?

[@pacsmile]

It's not clear to me why you added the diodes to the buttons for the low power mode, whatt i'm missing?

[@MarcelHolle]

Why are you using 5V Arduino Pro Minis instead of their 3.3V counterparts?

[@emoney0826]

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???

[@mikeywildct]

You, my friend, are the Arnold Schwarzenegger of hardware mods! :D

[@harshchikorde9495]

can u hack a tv to make it an oscilloscope? ??

[@greatscottlab]

A CRT TV should be possible......I put it on my to do list.

[@RaoulB.]

GreatScott! Yeah, it would be awesome

[@BoomBrush]

+GreatScott Thats a good idea. I believe old analog oscilloscopes used the voltage source to control where the electron beam goes on the CRT so it would be super interesting to see that being done over the composite video interface, if that's possible.

[@superdau]

The CRT in a TV works differently than one in an oscilloscope. In a TV the electron beam is deflected by a magnetic field, in an oscilloscope by an electric field. Sure you can also move the dot around on a TV, but the trace won't be anything like the real signal, because the beam in a TV can't be deflected fast enough (or more correctly won't follow the input signal linearily). For the time it takes to build anything around a CRT (ignoring the fact that playing around with stuff that's running on up to 25kV is rather stupid), you might as well use a raspi and build a digital oscilloscope.

[@ProLogic-dr9vv]

Yes this can be done to almost any tv , it just depends on how well you understand electronics and how not to get electrocuted .

[@mechemsiv]

Hey, maybe you have worked with PADI ioT stamp ? How it is compared to ESP-12F ESP82666

[@toomoii]

How long is the range of the transmitter? Is it strong enough for one wall?

[@greatscottlab]

Yes

[@rahulvc7791]

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.

[@Chrisknot94]

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!

[@robimudri4330]

hey great scott will you make anther q&a&c video.

[@TechTomorrowNetwork]

would this communication work between an arduino uno and an xbox controller? would be very useful

[@MrBobWareham]

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.

[@mixxx2005]

Thanks for your videos. What about range of this project? *in building real life scenario

[@jinweizhang1284]

Just wondering is the nRF24L01+ same as esp8826? They look so similar.

[@jeguimar8720]

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

[@raphaeljacob1548]

[@vishalchavda3663]

Because IR travels in line of sight... and Generally RF wale travels Omni directional... Thats y...

[@niter43]

vishal chavda that doesn't answer anything

[@raphaeljacob1548]

vishal chavda I mean: He should connect a wire from the ir transmissitter to the Arduino. so he can decode the ir signals and transmit them as RF

[@vishalchavda3663]

+Raphael Jacob first of all, IR LED will generate IR light.. so if he connects output of IR to Input of audrino input for RF then there will extra stage will include and that too of no necessary... so he directly get codes that will directly transmit through RF. That is why....

[@djtechsane]

No Raphael Means, also read the IR signal into the arduino. It would work and take alot less effort inside the remote... Not sure you're understanding what he means...
