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.

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.

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

Has an X-Carve CNC machine, which is precise and automatic
Uses a saw, paper templates and files to cut everything

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!

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.

Dude, I really really like all of your videos. I am an electrical engineer and this helps visualize lectures so well with practical examples.

[Retroweld]

Nice job! Excellent job editing!! Very well done.

[Tangylives]

Would it not have been easier to just have the papered side of the wood be on the inside of the case?

As usual, I'm completely lost on most of the technical stuff; It's still cool to watch. Great video!

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)

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

[rawrzbarz]

this Channel is dope. glad this was on my recommend list

[yeshecan]

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.

[AKSnowLeopard]

what I love most about this is that it can be endlessly modified! great vid.

[RelateGREAT]

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.

[des-Troy-ed]

this video was sick dude, I love these simple projects.

[PrinceWesterburg]

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! :)

[shockthemaven]

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

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.
