Hey, does it dry the battery too much or the battery cuts of before it gets to low voltage? I want to do a similar project, but Makita batteries stop charging after getting bellow a certain voltage 3 or 4 times, and i don't want to risk a expensive battery.
Can't say I've run into that problem, my batteries all still work fine. As far as I know the Makita batteries have a built-in controller that keeps just that from happening, you can't really de-charge them too far in my experience. They last very long in this thing anyway, I've had this run at full blast for 3-4 hours on one 5A battery and it still had 2 bars left
@@PhilVandelay Thank you for taking the time to answer me. I only have the newer star/yellow makita batteries, this is part of why i'm so worried. Makita batteries cost is absurd here in Brazil. I had a problem before with a makita vacuum that overdischarged the battery and than the charger refused to charge it, thankfully it was still on warranty. Sinde that happened i started to worry about using makita batteries in "dumb" devices, by that i mean devices that doesn't have internal overdischerge control. Thank you!
Better than that dummy speaker, was a set of PC speakers my parents had. A large round speaker grill (8" or so) on the side of the subwoofer enclosure, but the actual speaker driver of no more than 4" facing downwards out the bottom instead. I don't know how that doesn't classify as false advertising, but there's something very dishonest about these practices. Also, quick tip. You can cut those holes out with an adjustable circle cutter, nice and clean, and round.
Awesome work man, and nice background score. At least you didn't put this trashy EDM in the background like other Indian TH-camrs, special thanks for that.
I simply looked for the two spots where the two contact pieces that connect to the battery are soldered onto the board. Then I soldered my two wires on to the topside of those. You don't really need all the stuff on that board, I only bought the adapter as a shortcut so I have something that fits the battery. You can use it for USB charging too of course but in this case it's just so you don't have to build an entire adapter that the weirdly shaped batteries fit in
How do you keep the battery from over discharging? I recently bought a Bluetooth DC amplifier and an adapter for my milwaukee batteries that terminates positive and negative to 12ga wires. Last night I realized milwaukee tools have on board over discharge protection, leaving the raw battery vulnerable. I dont want to ruin my batteries, how would I prevent them from draining to dangerously low levels?
I'm not sure about Milwaukee, but with Makita the charging electronics are built in to the battery, not the tool, so it should work no matter what you connect it to. So far I haven't had any problems with this setup and I use the same adapter to charge my camera too, all my batteries still work fine, even though I've "emptied" them a few times - they charge just fine. I'm pretty sure it's the same for other tool brands, I think it's a common misconception that those chips sit in the tools themselves. It makes much more sense to put them into the battery.
@@PhilVandelay while I agree it is smarter to put charge protection into the battery instead of the tool, I simply don't have the kind of money to add Makita to my cordless tool arsenal. I was wondering what you would have done, had the charging protection been in the tool itself; as it is in my case. I've been thinking about getting a 5s BMS and using it only for over discharge protection, as I can easily pull m18 batteries off the dock to charge quickly on my milwaukee charger. I dont want to "charge the battery with the speaker" as it will defeat the main purpose of my build. My goal is to build a speaker that, when the battery dies I pull another m18 pack out of my jeep; swap them out constantly keeping one charged and never miss a beat with the tunes.
@@PhilVandelay but I am having a difficult time finding a low voltage cutoff circuit that I can adjust for my batteries, hence settling on using a BMS.
That's the best one yet I've seen. I've wanted one to take fishing or camping and being the battey you used be perfect thanks for the video keep having fun. God bless
What is the essay supposed to be on? Maybe we can help. Do an essay on how we have become such a disposable society, when so much of what gets thrown out, can be reused and made into something really cool, like a portable boom box from some speakers and a case that one may have lying around! Just saying.
I'm not taking the power from the USB outlets, it comes directly from the battery which is the reason for opening it and soldering on those cables. The adapter is just there to provide the connection because it's much easier than to build something that fits on that battery. So it's outputting 18V to the mini amp
i want to build a 500W RMS Bluetooth system, but i dont know what kind of rechargeable battery i can use, lets say i want to use the system at full load for 5 hours how much power will i need and what kind of battery i need please help me thank you
Nice! I want to add, it would be cool if you used some sealing foam on the inside edge so that the box is fully sealed when closed and a grill to protect the drivers. Also did you measure the box to find out the correct size for the bass reflex or not?
I actually added the foam later on like you said, and you're right it made a huge difference to the sound! I was going to add a grill soon but it kind of got lost on my to-do list... As for the reflex, I just used the same tube that was in the original speakers, I don't know much about speakers so I kind of just guessed everything. It's probably not the greatest sounding speaker out there but it suits my needs so far. Already tempted to make another one though...
I bought it on ebay but you can also get them on Amazon. There's a link in the description. I got the cheap knock off version but Makita also makes an official one.
For a portable sound system? Yes definitely. It's kind of hard to demonstrate on video unless you have a really good mic. I also upgraded this later by putting sealing tape all around the closing edges which helped a lot with the bass.
yeah passive radiator tend to be used in thinner boxes where theres not enough room for a port but alot of places seem to use them now because they look like an extra speaker. something like www.parts-express.com/dayton-audio-sd215-pr-8-passive-radiator--295-492 or a port in that box could help with the low end if you feel it lacks it. if the box doesnt seal well when its closed a passive radiator wont work very well though.
I have actually made a small modification to this since the video, I've added sealing foam tape (made for doors and windows) around the edges of the inside box and it has had a huge imapct on sound quality now that it's somewhat air sealed. I got plenty of bass now and am even more satisfied with the result! I also get no considerable vibration even at high volume anymore (the box being quite heavy helps with this). Thank you for your insights, speaker building seems to be a rabbit hole and I'm already tempted to build some more :)
im with you. my dad has some old but very high end towers in his home audio setup they were like 3000 a pair new and he blew a midrange and i found him replacements but i had to buy 2 to get them so i got the extra and now i want to build something with it but i havent decided what route i want to go yet
Thinking of using a Bluetooth car radio .. has all built in...nice build
Very nice project. Greetings from sunny Jamaica.
This dummy speaker is not passive radiator because it doesn't have holes into the metal basket! This is realy dummy speaker!
yuppers
hey what is the first song that you play while showing the finished product? the slow one
I've spent 3 hours watching your videos tonight btw, you're cool as hell man

How do you do the wiring part of the charger? I can't see how you've done the wires when you've soldered them? Cheers

I opened one up not to long ago, had the same thing when i found that speaker that wasn't a speaker..... then I learnt what radiators arw
Nice build I've got one of those cases, I think I might have a go.
Great idea to reuse old stuff
What amp is that?
TIL what is and isn't a passive radiator! Nice build!
Where do I get that part you put on the battery?
I bought it on ebay, just search for "Makita USB adapter" or whatever tool brand you have, you can also find them for other brands like DeWalt etc.
I'm supposed to be doing a 2000 word essay but I'll just watch this.

That USB drill adapter outputs only 5v / 2.1 amps.. that's super minimal power, is it not?
I'm not taking the power from the USB outlets, it comes directly from the battery which is the reason for opening it and soldering on those cables. The adapter is just there to provide the connection because it's much easier than to build something that fits on that battery. So it's outputting 18V to the mini amp
Can u send link for the Bluetooth
Good looking box!
Why didn't you use MDF ?
Because I'm cheap and I mostly used stuff I had around the shop at that time
Wow long does the battery last
Is it sounding live that bad too?
You forgot a sealant, and: Is a reflex port on a right side?
Great project!!!
Amazing
Fun project! Any thoughts about protecting the speakers with a metal grill of some kind?
i want to build a 500W RMS Bluetooth system, but i dont know what kind of rechargeable battery i can use, lets say i want to use the system at full load for 5 hours how much power will i need and what kind of battery i need please help me thank you
you should use a car battery or motorcycle with an ac/dc adapter
If the amp runs on DC, and the output of all batteries is DC..why the need for ac/dc adapter?? Do you mean charger for the car battery?
Nice! I want to add, it would be cool if you used some sealing foam on the inside edge so that the box is fully sealed when closed and a grill to protect the drivers. Also did you measure the box to find out the correct size for the bass reflex or not?

I think that "dummy speaker" was a passive radiator
Lexvox LP the back was sealed
koupe88 my mistake didnt really see that😂🤦♂️
If you drilled the back out of the dummy speaker you could probably use it as a radiator.
D twist Rewind true
lol i didnt see that either
Wow. Uses the same amp!!! I love that amp!!!
Yeah it's really good for the price. Except for that awful melody when you switch it on
Phil Vandelay that melody is fine compared to mine. "Bluetooth mode!" And when you plug a jack "input mode!"
Yeah I get the same ones. I just cut them out of the video ;)
Nice build! Where did you buy the makita battery Charing part?
I bought it on ebay but you can also get them on Amazon. There's a link in the description. I got the cheap knock off version but Makita also makes an official one.
Thanks, I never notice it.
Nice build :)
Very Good !! Like !!
5:34 song plzz
Did you ever figure out this song??
Need some speaker covers and be cleaned up
Be honest. Does it have enough bass?
Depends on what you consider enough
Do you consider it enough?
For a portable sound system? Yes definitely. It's kind of hard to demonstrate on video unless you have a really good mic. I also upgraded this later by putting sealing tape all around the closing edges which helped a lot with the bass.
Nice. 👍🏻👍🏻
What's the point?
Brasileiros agradecem ;)
Muito legal !!!
The dummy speaker as you called it is whats called a passive radiator or bass radiator. its basically a alternative to a port
Thanks! I suspected that it probably wasn't just there for looks
yeah passive radiator tend to be used in thinner boxes where theres not enough room for a port but alot of places seem to use them now because they look like an extra speaker. something like www.parts-express.com/dayton-audio-sd215-pr-8-passive-radiator--295-492 or a port in that box could help with the low end if you feel it lacks it. if the box doesnt seal well when its closed a passive radiator wont work very well though.

Atergia maybe try making a small mono FM radio, I've made one and it sounds really good! I used a 3,5" driver from Dayton audio
Я думал только в России обманывают)))
А так очень хороший бумбокс получился, лайк👍😉...
очень все плохо в европе... не едь сюда...
It's obviously not a dummy speaker. It's a passive radiator witch is very useful and can up to double the volume and bass level.
Not *that* obvious, as the back of it is completely enclosed - no way for air to pass and to pick up resonating frequencies.
I think the Dummy speaker was silent through the whole video !! Hahahahaha WTF !!
No port was needed. Not enough power. Would have had much tighter bass without the port.
Aowww Tocando musica Brasileira ai ficou bomm !!! #brazil
je ne pense pas que le système d'amplification soit suffisamment puisant pour alimenter de tel speakers .
Nice work
I like how you made sure there's no stereo separation by putting the two tweeters as close as possible.. GENIUS
Thanks 😀
Can you please link me to your builds that do things "properly"? 🙄
что за музыка фоном играет?
00:38 00:48 😂
Pls do bass test
Nice build
Still sounds as an ipad😂
Knapp :D

brazilian music
it's a passive radiator
Luca Mongiardo it is not, it is sealed from behind, so air can't get to the cone.
man how the hell u making this when you don't' know what a passive radiator is??
It's not a passive radiator
Faraaz Yousaf you should delete your comment. he obviously knows what a passive radiator is. But this thing in the video wasn't. It was sealed...
how was that a passive radiator, the back of it was sealed. how is the air pressure supposed to move it if the back is sealed?
Speaker dummy und bass reflex 🙄🥺
Do you like brazilian music ?
Eu sou brasileiro
Yeah there's a great vibe to brazilian music :)
Not a dummy speaker it was a passive radiator
Nerd Central nope. it was sealed
J
dam man.. you just destroy a rare pair of hi fi acoustic boxes designed by Mark Levinson to transform it in a ugly diy boombox.. come on
love these mute videos [not]
Lame!
Salve meu Brasil Brasileiro
Eo fresco é kkkk
