In this project I will show you how to build a simple portable bluetooth speaker that can play its tunes up to 30 hours continuously. Most of the used components can be found for only 22$ in total which makes this a pretty low budget project.

2011 Lookalike by Bartlebeats
Killing Time, Kevin MacLeod (incompetech.com) - Věda a technologie
A couple tips: first, you could put insulating foam on the inside of the box to get a better sound quality; second, you could've used the blue part of the rgb led to signaling that the speaker is on, using a diode between the common anode and the BT board led anode to ensure that it doesn't get current when it souldn't.
Could you help me create my own speaker please?
Has an X-Carve CNC machine, which is precise and automatic
Uses a saw, paper templates and files to cut everything
Correct and if you think a bit further you might realize why I did it like that.
Because you want to show that everybody can make it ;)
because the point is to teach that it can be done by anyone without expensive stuff? hence the "simple and cheap" title
thug life greattscott
On top of that, he spent less time doing it manually :D
i wish you could make a tutorial on reprograming such a (or similar) bluetooth module, so there would not be a voice when the module is turned on
any news?
@@nicoom it's been 5 years since this guy commented
@@____Andrew____ that's why he should
Agree. that sound is very irritating
Or a piano note to indicate it's connected
I really like the videos you're doing nowadays - But as I'm just starting out with projects of my own, seeing your simpler times, showing the exact methods on how to do everything by hand, is really a breath of fresh air and does motivate me more :)
I love when you say "with", it sounds like woof!
As usual, I'm completely lost on most of the technical stuff; It's still cool to watch. Great video!
Dude, I really really like all of your videos. I am an electrical engineer and this helps visualize lectures so well with practical examples.
I love how I always end up learning something appart from the project with your vídeos... I missed that part a little bit this time. Cool project anyway.! Thanks!
These are not acoustic suspension drivers so a bass port would help. Also try damping the box and use hollow fibre from an old duvet for extended bass! :)
this video was sick dude, I love these simple projects.
This is EXACTLY WHAT I was looking for. Great video. Loved the outcome. Great job my dude!!
I ordered this board from eBay after watching your video. I pulled speakers from a Sony TV that has same speaker connector so no soldering. Can't wait to try it.
this Channel is dope. glad this was on my recommend list
Nice job! Excellent job editing!! Very well done.
Thanks
GreatScott! add a passive radiator to it, and you will gain a lot more bass
Taunter Atwill i did hear it, but i am not saying that is lacks bass it was a suggetstion
Hey to attach my two lithium batteries together, can I just solder a piece of wire to connect them or should I find a thin sheet of metal like in the video?
And why did you attach the positive to positive? And neg to neg?
Adding holes to the back of the speaker improves quality because it prevents the pressure waves created by the inside of the speaker cone from echoing inside the speaker and interfering with the cones motion. This is basically what a passive speaker does ( I remember you mentioning them in a previous video)
Just what I was looking for-I couldn’t figure out the battery and electronic components for my speaker project. This was very helpful. Thank you.
A tip that might be useful for you in future, when sticking the patterns to the wood, put a layer of masking tape on first, then glue the pattern to the masking tape, that allows you to easily peal of the tape at the end instead of having to deal with the glue.
Good idea
Also, Pritt is water soluble, so you should soften the glue with water. I don't know it acetone will dissolve it.
Am I missing something? Why not just use pencil instead of going to all that trouble? Or even just cut the pattern out directly on the wood leaving the line cut by the xacto knife as the guide
I was thinking alike. I usually just use a fine tip auto pencil when being precise. A pen light standard pen even works using light strokes since sanding is required for that smooth elegant look. Although if measured and outlined correctly and precisely then the lines should be just barely cut away anyways.
@@michaelw7540 if he had access to an - admittedly expensive - laser cutter, things would have been really accurate.
LOL!!! that exact same " Za blutus divais is rid to pear " plays when i turn on an actual BT speaker (definately chinese ) I guess it's a template
Lol mine plays it too xD
perfect engrish
The module says:
The bluetooth driver is ready to pair.
No Chinese or German needed |-)
+VideoDaze Its "the bluetooth device"
VideoDaze why he didn't used the first module , it looks very easy , but instead he made on his own . what is the difference ?
I love your videos..i watch them over and over til i memorize them by heart..and lookup the components on each ready-made circuits so that whenever I go scavanging components, I keep them and make your projects to save money..keep it up!
Now this is useful! Thank you Scott!
You should make a video about making a standalone CD player from a computer CD player!
Would it not have been easier to just have the papered side of the wood be on the inside of the case?
Probably sound slightly better too, the more absorbent the inner walls the fewer internal reflections. Though wool would be even better.
So you're new huh?
Big time
Welcome to the internet! 'Round these hur purts weh don't do things thuh... easy wayuh.
@@edism 88 iui 88ijj
Hi, love your videos. I'm just wondering if you've considered adding passive radiators to the speakers? It's a really cheap way to improve your audio quality significantly. And also, what about matching speaker wattage with amp wattage? I know it's a disputed subject, but perhaps that would be material for a future video to settle it once and for all...
what I love most about this is that it can be endlessly modified! great vid.
Yeah! I modified mine and put a live duck in there. I blasted a bunch of Primus and when I let the duck out I discovered it had died. I was disappointed, but then it's bloated corpse exploded and in it's stomach was a can of Pork Soda and I was feeling just fine.
@@HairyTheCandyMan nice my little brother survived
The "Stay creative" catchphrase at the end of the video get's more and more enthusiastic with every video :P Great videos, keep it up!
hi Great....wait...wait...give me the explanation for those 2 resistors...where did you install and the exact value of them + why you need them?
thanks GREAT.
could you make a device which can be plugged into an audio port an then controls an led strip, so if you are listening to musik the led strip flickers to the beat?
This is the best thing I've seen today. I will save some cash to make one. Thank you, Sir Scott
Thank You Scott for making such great videos with passion!
Wait? Is that why the channel is Great Scott? I didn't know his name! lolol
can u make a guitar effect pedal . thanx, great vid
Great, Scott! 😀
ALWAYS interesting, informative, and entertaining. Keep up the great work!
(1) This is exactly the information I was looking for. Thank you!
(2)They make removable glue sticks.
(3) Mineral spirits (paint thinner) works better for removing this kind of glue because it has a much slower evaporation rate which means more time to break down the glue.
You should definitely add a carry handle on top of the case so that it would be truly "portable" :)
BTW, is it really that good (volume/distortions-wise) as-is w/o any amplification circuits?
P.S Oh, and, of course, add some VU meters :D
GreatScott!
I've did everything like you, but when i tried to set the voltage for the boost converters, they simply didn't change the voltage, at all, i tried 5 of them, so i must be doing something wrong, could you help me please?
Much Thanks in advance,
SD
oh wow this looks like an awesome project. about to get into woodturning. i think i'll turn up a case for this thing and make my own!
One of my friends just made 5 of these wilt his Makerlab class, they just laser cut the case and put a 5 volt usb changer in the case also, to changers the phones :)
A super fun project. Thanks for the video
Awesome .... where is the fun in just ordering a Sony what’s-it-called from Amazon!!
Some suggestions:
Add a handle on top for easier carrying
Add some holes on the back so that the Speakers have more air to move arround
also: If I wanted to add some volume controll, what would I have to do?
I'm a big fan of your channel and might consider building this one,
Grüße aus Österreich.
If you want a volume knob, you need to add a potentiometer between the audio output of the bluetooth IC and the audio input of the PAM8403. Not that easy to do. It is much easier to control the volume on your phone.
OK thanks
K1ngjulien_ it's a tweeter... Doesn't need porting, or does it?
Actually not that hard, you just bend the pin on one of the ICs and solder the pot in between the ground, the bent pin and the solder pad.
Das sind volltöner da ist nen port kontraproduktiv
Really nice project. I put this Setup into a Bose sundlink mini, and it is working very well.
You can use soft foam inside the speaker to dampen the vibration. It improves the low tones too.
Das würde ich mal ausnahmsweise nach bauen. Mach mal bitte mehr so Projekte die man auch gebrauchen kann.
How did you start making electronics?
I think he once said that he is an engineering student.
K1ngjulien_ That explains it.
ElyK he is electro engineer, thats his job from age of 18
I like the way, he has stuff like Microwave and Speakers lying around!
if you add large passive radiators to this enclosure you can feel more low frequencies !!
Cool project ... thumbs up !!
Is there a way to silence that anoying loud talking? I have this module and that talking makes it unusable.
me2 it's anoying when you try to play quite music
If you mean background noise then you could use an Isolating Converter! Just search it up and you'll get an idea what I mean.
why not use your xcarve?
Quote by Greatscott: Because it is supposed to be a simple project that other can remake. Using a CNC would only scare off viewers.
A few mounts ago I bought an Arduino 101 and it has a Bluetooth antenna on it. It can also tell what way it is tilting by using those switches with ball beings in them. It's a great board.
I love all the pricing info! It's really makes it seem like it's a project that I can get started on
seem....
Can you make a smart mirror tutorial
You should use a better amplifier for those speakers because those are from logitech z5500 :)
+spotify95 seems like you know something about this, what would happen when i connect 2x 8W speakers to this? ^^
but nothing will be destroyed or something when i use 8W or even 10W Speakers? :)
Okay, thank you very much!
I wouldn't recommend giving them over 10 watts though, unless you have a high pass filter and a bigger woofer with a low pass filter so that you don't blow the tang band speakers. Sources? I have some old z906 speakers.
how can i find a cheap 800 watt amp?
i love your videos, quick and in depth, and nicely put together :)
I don't get how people don't like this. this is amazing.
what the resistor value of the rgb led
in all honesty, i dont think it matters. i think hes just trying to prevent a short circuit, but idk I honestly have no idea what im talking about.
Jesus Christ, i could have guessed that had i known what the fuck an led even was lol. or... if i wasnt drunk off my ass... nah man i make shit like this as a hobby but ive never even dealt with leds because... well why would I? Leds dont make my speakers sound better now do they.
AY SHIT WHILE IM HERE I GOT A QUESTION
okay so electricity flows from anode, to cathode, right? well then, how the hell do vacuum tubes work?
Did you got the answer? Because i need to know.
I calculated it , must be 100 ohm resistor but i may be wrong so :p
"The Bluetooth device is connected successfully" how can i change this sound?
It's probably flashed onto the controller itself. Unless you find out what firmware is on that thing I'd say there is not direct way to do that. Then again workarounds are possible. The board should provide some other digital way for signaling that the connection has been established. You can then use your own board to work with that signal and output different audio, light up a LED or something else.
Lookup the datasheet for the main IC on the Bluetooth board and see if it offers a program to reprogram the module via SPI or other interface.
use Arduino or Rasberrypi
Love the outcome of the project! Very neat!
great tutorial! I just saw where somebody converted drive in speakers to bluetooth and went straight to youtube! thank you!
Why did you not use xcrave?
And a scroll saw is simple?
I dont have any wood working machines.
I only have a cheap bastard file and that is it.
The scroll saw is for precision cuts, you don't need one, but it would make it easier
I feel like i have seen this already in the past, am i trippin?
muh1h1 no
muh1h1 it's for sure not the first DIY Bluetooth speaker build from these components. In some vids they use another amp, or another Bluetooth receiver or whatever.
So nothing completely new here but still a welcome add on and some new ideas. The case done with the scroll saw is very 👍
Danke für das wiedermacht tolle Video!
Howard2k79 Yep, i just thought i had seen this exact video already, but i must be mistaking :)
Maybe you can see into the future and now you are just reliving that memory. Can you predict my future ? Will I ever unsubscribe from GreatScott! ?
DjGabuza noone will !
Like your making very much, excellent handwork!
Great video. I really like how you always mention the specifics of each part. It makes it very easy to find them online. Thanks for your efforts!
Your better whit electronics than whit wood😂
You need 1.21 gigawatts to power this speaker though...
And a flux capacitor!!
wow an amazing Bluetooth speaker! well done!💪👍
Really great on, I will try it, just a little problem its a little hard to find components here in Brazil, but thank you very much for sharing this video and all other information, thumbs up man
any way of changing the Chinese to English?
i bought 2 days ago some ne5555
You'd have to figure out how to modify the firmware, if that's possible.
NE555 It doesn't "speak" Chinese. it just has an accent.
most likely not, because the datasheet isnt availiable :/
but what i found out about this ic is, that the ic has support for bluetooth, radio, usb and sd cards ;)
Maybe it's just me, but she sounds half german, half chinese ;)
for the next project can you make an arcade machine
It is already on my to do list.
Ok thanks for the 1 min answer ;-) continue your great job
I watched this video again, but this time with my own and in many points different DIY speaker
wow! 400.000 subscribers. Congratulations!!
this isn't actually cheaper than manufactured bt speakers though
sinephase You are correct it's not exactly cheaper. Most DIY projects will rarely come out cheaper and that's with out taking into account the necessary tools the margins are not on our side. This is one of those project that we do just because we can.
I agree, it's fun to do so because we can. That being said..it's the clickbaity phrases in the titles that make it sound like it's easier and cheaper to do so yourself rather than buy one that I get pissed about.
from geting the part aroud me i got this for like 7 box :)(but i agree that tools are expensive anyway)
To be fair the battery life of the speaker he built is significantly longer than any Bluetooth speaker Ive ever bought for less
That's true, but you can fine-tune the signal by yourself, for example by inserting different high- and lowpass filters to drive different kinds of speakers, for example 2 extra tweeters that only get fed the high frequency sounds. Of course you'd need some more parts for that but it would be possible, and you can make the speakerbox sound just as you like it
lol id rather buy a ready bluetooth speaker than make one with that price tag.. : /
When u increase your budget to like 80 bucks, your speaker sounds awesome (needs some simple calcs) and it can easily compete against something like an 200 $ JBL Box (:
(f.i. Using some Bluetooth amplifier from Amazon (~15$), 2 Visatron FR chassis (40-50$)); and some individual stuff like, battery and voltage indicator or USB charging ports (and a descend to good EQ on your Phone)
PM:FAIZLAMIZ :P where's the fun in that
Do you have some additional information about a real good setup? My budget would be up to 100 bucks, but should be worth spending my time as well, so would appreciate good sound quality ;)
Mine is a 8mm plywood box with ~ 12l of volume ~(300x200x200mm) with 2x 20mm diameter x180mm circular Bassreflexes
the Drivers are 2x [Visatron FR-10 4Ohms] driven by a ~15€ 2x25W Bluetooth audio amplifier from Amazon (still a chinese one).
Some wool for stuffing things out and some wooden struts to reduce the oscillation of the case (for tighter sound)..
I am satisfied with the result. But my box really demands an external equalizer to sound awesome (there are plenty of them in app stores, but you will be restricted to use a smartphone)
You may want to take into account whenever you add some volume like Batteries (f.i. LiPo, LiIon; or simply a Pb accumulator). Any significant change to the volume should be compensated by increasing the dimensions to maintain roughly 12 liters of air (for 2x Visatron FR-10); there a multiple tools for calculations out there :)
Finally, some utility may be pretty neat:
Stuff like Voltmeter for Vbat; USB charger port (my mobile has to run the EQ through the cpu and uses more power); any kind of charging port; some lights (?) etc; MUTE SWITCH when using shitty developed amplifiers which do all peeps (powerup / volume + / - / play / stop etc) with 100% of the volume! (me
I'm building a Totoro/green themed one of these for my GF with a handle that doubles as a cellphone stand and a compartment on one side to drop your phone in for the steamy shower. It is also being created out of used speakers I got at a second hand store and never put into service. It has passive membranes and a woofer as well. Try any get anything remotely similar by buying it and you cant.
Very good project!!Congrats from Bulgaria
Cool! I suggest you add a battery indicator so you can still know the battery percentage. I use volt meter on mine and works well
great job GreatScott!.your videos are always usefull
Yet another AWESOME project!
nice little board, going to solder some rca jacks to one of these and plug it into my old stereo...i noticed 50Wx2 amplifier boards on ebay as well if people are looking for higher powered speakers.
Great idea! I may hack my old stereo radio to have Bluetooth functionality one day - GreatScott has a video on literally everything.
Great video. Congratulations!
A tip with the templates, instead of glue it directly to the wood, first you put some tape on the wood and after you glue it on the tape, so it´ll be removed easily.
Sorry about my english
Your videos are simply awesome ! Thumbs up
I have no idea what this guy is talking about but I love to watch. he's like a crafty engineer or mad scientist. and I thought I was smart
really great Scott!! thanks a ton, very inspiring me.
Sir watching your videos in full hd is greattt
Great video, though one suggestion. You can combine the boost converter and the li ion protection board by using one of the 18650 based power bank PCBs found on eBay. They supply around an amp, simplify the build a bit, and is less expensive.
to simplify the build and keep it cheap, buy a bluetooth speaker.
great idea! it comes with charge board and usb brakout so it is cheaper too at the end
You should ad passive radiator or a bass port. Great video, as allways!
Super slick and awesome vid!! Thanks!!
Highly recommend to use CSR8645 model and an op amp to do this job. It's sound quality is amazing. Make sure the op amp is good and has enough power to drive 3w speakers. You parallel to solve it. This setup will provide HlFl quality with APT X supported.
Before apt-x, amplifier is more important on this little project. I use 1 dollard bluetooth dongle receaver on monitoring speaker, and sound quality is awesome. APT-x is the final touch :D
I would love to see how to use the CSR8645 to add streaming audio and handsfree calling to old car stereo. The ultimate solution would be to connect it to the stereo via USB so that song titles could be displayed on radio and possibly call details from handsfree calls
If you dont want aptx, CSR 8635 is Also not bad. You can program it like An arduino pro mini. It outputs very low power signals and Could be amplified using A class D amp. There is no need for professional opamp. Its just not worth of it. I Am making An earphone amp using CSR8645 and AD827. I might use AD712.
wzd leo how do you program it ? The CSR8635 I mean
Always love your vids.
I am sri lankan person . Realy helpful for me. Good explain .tanks for that sir
dindinmodern speakers are also very good. I've been using it for over a year now and I use it a lot when I'm outdoors
Amazing skill bro! That´s the way i like electronics!
Very well done video and encouraging too. Thank you. What were your thoughts about some venting in case the batteries get warm? And giving each speaker it's own separate "chamber" with tuned ports to let the speakers fully and independently "flex"? You mak get even a louder and more natural sound. Thanks again!
This is excellent, thanks for posting!!
very cool. watched a couple of your videos. keep it up!
awesome project the components came in handy for my own version of the speaker thanks.
Thank you.
I got all these parts within different appliances. I've been wanting to learn how to do what you just did.
So I just collected all the pieces except solder hahahah I lost my soldering gun....
nice work scott!
GreatScott, I love your channel! I'm currently in school for electronics and you really take the time and effort to explain things well!
I purchased everything on your parts list to convert a few speakers I have into Bluetooth... After receiving the Bluetooth amp, I plugged it in and I get some annoying feedback, would you have any clue as to what would be causing this?
wow,I love your homemade portable speaker!😍😍😍
Great work Scott
Congrats for the 600k :)
+Millenium Bass Thanks
That was the video that i was waiting for ☺️👍
