I new to ardunio and your step by step style of describing your developing ideas is just the way to do it for us here. I have learnt more from your one video than 10 of the last videos I have watched .....keep it up mate
Cool. This brings back happy memories of my speech communication experiments over a beam of torch light. Considering that it was just a standard torch bulb in a reflector, the sound quality was surprisingly good. Keep up the good work bro :) .
Also sent audio through the ground, amplifier + two pieces of copper tube to send, hich impedance headphones with croc cips to receive, got about 50 yards.
Really great project and you will have spares as well. I was astonished when you plugged it in with all parts powered up and was really wanting to hear the best of the fidelity, with some ~100hz Subbed and parts are on the way. Looks like focusing won't be an issue at distance. and you can wirelessly send out some music to your livestock as they visit the watering trough. Best one i have seen all week!
Awesome. Thanks for sharing. Most probably the reason it didn't work at short range when you were pointing it directly at the receiver was that the signal was so strong it was saturating the receiver even for low part of the (amplitude) modulation. This wasn't an issue at longer distances. Same happens in RF so. But you already know all of this :)
Thanks for the video I got this to work just fine. Though at first I had trouble converting one of my audio files to the correct format. Here are the terminal commands I used on Ubuntu (using WSL on windows) you can install with "sudo apt-get install mplayer sox" then run these commands "mplayer -ao pcm input.mp3" "sox audiodump.wav -c 1 -r 8000 -b 8 -e unsigned-integer output.wav"
Nice practical example. That reminds me quite old czech electronics book and there was ligtbulb and big lens instead of laser. Now we can do this magic for few dollars on hundred meters. Some downsampled wav sound could be improved if you disable dithering during conversion. Sox or Audacity is doing that in default. But strange noise artefacts cas appear sometimes. Fellow videoblogger
I did a variant with IR remote control detectors, requires a carrier and full on/off pulsing to "train" the internal AGC - just need a carrier of the receiver's specific frequency modulated on it. ESPs have a pretty good internal block to do this directly. This method knocks down the potential bandwidth to just a fraction of the carrier frequency, but the upside is that it's much more resistant to interference (lowering digital bit-errors). I can bounce off a building (not into a window but a solid surface, typically concrete) for "non-line of sight" links using a spotter's scope for the IR receiver, with this I can transmit data >5 miles using a fairly low power TTL IR laser module. Another copy on the other side makes it a bi-directional serial link.
I think the reason why it doesn't work very well at close range when pointing right at the detector is due to light saturation. When it's farther away the detector is seeing every single change in the small pulses of light. When it's up close like that, there will likely be very small forms of attenuation and reflection happening which interrupt the pulses as seen by the detector and sort of wash them out. This is why, for these kinds of applications, optical fiber is used instead of a pure beam. It can go much further through that as well.
Excellent work! Do you have plans on going further into sending / receiving data? Perhaps use Raspberry Pi's at each end, still using serial ports, then run PPP over serial to have a proper IP connection. So the laser would be layer 1, PPP would be layer 2 then IPv4 layer 3, etc...
I also only used the arduino to power the light sensor - I sent analogue audio waves with a “custom” wiring from the TTL/PWM module and a head phone amp to get into the tolerance range as its USB lvls which also happen to be about the max V out on a set of phones signal - so it’s fully analogue - on the light receiver side i wired the sensor into a powered video microphone and fed to a reel to reel tape deck just to be extra analogue
Excellent. I was looking at at UHF one-shot for short range data transfer between a workshop and office. HC-12s are not an option sadly... I reckon this might be the way forward. gonna play, but as it over-flies other peoples properties, I am going to tweak it so it isn't "marking" all the time... the pulses will be short enough that no-one should notice ;)
Man, I SO wish this could go further. I need to get internet to my parents house few miles away (no options) and can't figure out anything that isn't cost prohibitive or sucks.
Hey this is great! I would like to ask where you can get the module that has the SD card inside. As well as how you connected your other arduino to speakers. Thanks ahead!
Burning hand joke - man, you got me ! LoL !!! Would have been interesting to hear voice transmission. But i guess from what i heard (music) it would be no problem. Nice Video, interesting project !
Kinda cool, you could perhaps attach a mirror to a window and shine the laser into the mirror and if you could get a line up on the returned bounced dot use it as a form of "remote microphone".
Hi, thank for sharing. I added this to my ever expanding things to do list. I am not sure my suggestion is going to work with lasers, but in RF/ line transmission engineering, you can increase the range by reducing the data speed.The Voyager1 space craft I believe started off a 115kbps at Jupiter, but its last comms was about 1k4bps only because the transmission system can't go slower. So if you want to try to increase the range drop your data rate to a low rate, but faster than 64,000bps
I think the laser may be overloading the sensor when you're pointing it at at at close range. That round shape on the front of the sensor is a "built-in" lens to direct the light in to the sensor. Those particular sensors were never meant to detect laser light. Just a guess, but I suspect that's what was happening.
As you know exactly how often you'll send/receive serial input you could put the code to change "theByte" in a timer interrupt instead of the loop function. That should fix the issue with the sound play-back speed, though it would make the code more complicated
The brass thingy on the laser has a lens and rotates for beam adjustment, you could trim it a bit and probably get several kilometers of range :p I think the receiver PCB might be making it harder to archieve higher baudrates, as it seems to be a repurposed ds18b20 temperature sensor board. Cool video, thanks a lot. Gonna experiment a bit with fiber.
I’ve sent audio using the arduino light sensor and the TTL/PWM on the laser router through a head phone amp - i run a couple sets - one that is on or off at threshold and the other is the entire sound wave - when those low 808s hit it looks pretty wild with transients on the others without PWM
No need to use the Audio output Sketch, i have used this sketch for the output audio: int buz = 11; // Buzzer or Speaker connected to digital pin 11 int inPin = 7; // The input signal from receiver connected to digital pin 7 int val = 0; // variable to store the read value void setup() { pinMode(buz, OUTPUT); // sets the digital pin 11 as output pinMode(inPin, INPUT); // sets the digital pin 7 as input } void loop() { val = digitalRead(inPin); // read the input pin digitalWrite(buz, val); // Set the read value in the output } P.s: Sorry for bad english, i tryed my best :)
Hi really nice video, i want to use the laser sensors to create a piano like the one in the movie big, but i will built in in a stairs , do you think sensors like those will be enough for 5 meters distance?
I'm pretty sure this laser stuff can do SPDIF as well. That's CD quality audio :) I guess I'll find out as soon as the parts arrive, since I just ordered them :D
I have purchase the KY-008 laser with the associated sensor board. For my project I only need the 3 pin sensor but I'm unable to identify it, and I can't seem to find any references to it on all the sites that are selling it. Does anyone know the Mfr and Part Number of the detector which inserts into the 3 pin socket? Thanks!!!
if you directionaly light shield the sensor with a tube parallel to the laser id say you would get longer range again because the ambient light on other axis would have less sensor saturation impact making the digital differential easier to distinguish
Wonder if FPV could be transmitted over it, could put it on your front fence to meet visitors before remote opening the gate. What sorta bandwidth ranges do FPV systems typically work with? What's cool about it is that unlike radio stuff, the bandwidth can be doubled/tripled/etc by just adding more lasers and sensors. More and more laser pixels, eventually you approach a point where you're transmitting with the laser equivalent of a projector, and receiving with the equivalent of a high resolution camera with a telescope. Hmm... actually laser projectors are already a thing... i wonder...
+iforce2d I wonder if it is possible to make a noise helmet with an arduino (or raspberry pi). I know the physics behind this technology. But I ask myself a lot of question on how to analyze and then send the sound in phase opposition of external noise. Does anyone have any advice? How to analyze sounds? Should I use an arduino or a raspberry pi?
Hi, may ask if (and how much) the daylight does interfere on the receiver? The first test you've done seem being done in normal daylight while the later ones seem to have been done in evening light. I've read on the products description that using them in the dark is recommended.
This video.. I'm.. ecstatic! I love you! lol.. well, this song, ever since I heard it for the first time.. the original, I've had goosebumps all over.. I've even talked with Alan Walker about both Fade and Faded how much it affects me and how much I love them.. I don't know what it is, but these two songs are like drugs are for those who take those.. Nothing can make me feel so well as those two songs, really nothing! I listen to at least one of them every single day since they were released, crazy? ;) haha Anyhow, laser and laser transmission is so awesome and you combine it with the best possible song.. If it were up to me you would win an Oscar just for this video alone =D Great video and thanks for sharing! =)
Oh and have you thought about optical/toslink anything? Its very similar, but I think - I don't know - it uses leds instead of laser? Even if lasers these days mostly are leds as well, if I've understood correctly. Anyhow, I've been wanting to get some toslink connectors and well, do exactly what you did in this video.. But they are so hard to find, extinct? and they are usually a lot more expensive. I will get some of these laser versions instead, as it seems to be the exact same thing, just without the optical cable in between ;) I guess you could use a toslink cable between as well, but would be hard holding it in place without some sort of connector of course.
It's probably 15yrs ago I bought a new motherboard and didn't know I was supposed to buy an adapter to get optical spdif out, well I put red led on spdif pins and pointed it to the optical fibre and it worked. Dolby digital!
Could you reduce the voltage going to the laser for short range and increase for long? Either way.. this is awesome!
8 ปีที่แล้ว
That’s amazing! Actually, you might be able to use it as reliable data transmission. Just repeat the sequence few times and receive checksum (also few times) for comparison.
nice! wouldnt it be possible to make an easy + cheap fpv lap timer based on those components? maybe add 2-3 receivers and a diffusor to the emmitting diode?
This project could be done with purely analogue electronics and achieve HIFI sound. Using the same techniques IR remote control receivers use, combined with that laser would give you some serious range :-) Miles?
Hagledesperado Digital as in on/off but you can use pulse position modulation and modulate the time between pulses by the audio. I did this many years ago with IR LED's and the range indoors as well as sound quality were excellent, cheap laser diodes were not available then :-(
I would say that when it's pointing at the front there is too much power, maybe a voltage divider to attenuate the power to the 5v input for close range?
8000Hz is just the frequency of the audio sample in this case. The serial connection itself is 115200 baud which I think is as fast as the arduino can do. I don't know what the limit of the laser detector would be.
I keep getting an error message “avrdude: stk500v2_RecieveMessage(): timeout” in the receiver side although I checked the port and board in tools menu, what causes this error? Knowing that I am using Arduino Mega
Great video. You captured my 6 year old's attention so now I need to order a couple of these so we can experiment... Just curious I noted that on banggood's site they claim the receiver is susceptible to interference. Did you happen to try it outside with the sun up further, and if so, how reliable was it?
I think that when you point the laser direct at the sensor the light is too bright and it clips, or the difference between the normal light and the beam is'nt big enough
A great practical use could be laser tag. Make some guns that shoot lasers when the button is pressed and have a receiver players wear that reduces a life point and makes a noise when it gets hit! Could send information about who hit you and other things
+muh1h1 I had once pondered something similar,to do wireless toslink/spdif transmission over a fair distance. I had also wondered about using an IR laser module,so it wouldn't be visible to the naked eye.

you can listen in on conversations from long distances by measuring the vibration off the window pane and modulating that into a sound signal.

nice choice in music
if you can set your camera to PAL or 25/50hz it'll get rid of that flicker - curious what the frequency responce of the detector is.
Молодец если одним словом. Идея хорошая.
After a PWMDAC, a small RC low pass filter could enhance the output for smoother response.

I wonder what the absolute maximum range of it is, I also wonder if you could jerry-rig it to a stronger laser.

A great practical use could be laser tag. Make some guns that shoot lasers when the button is pressed and have a receiver players wear that reduces a life point and makes a noise when it gets hit! Could send information about who hit you and other things

Of course you could possibly use a reflective dish to concentrate laser back to a point
