In this project I will show you how I turned an old bookshelf speaker into an awesome portable boombox. It features a battery run-time of 100h, a battery level indicator, USB charging ports and a 20W amp. Those features make it perfect for all outdoor trips. Let's get started!

I like recycling projects - always good to make them your own with customisations. Great build!

This is I think one of my favorite projects you did...first the car radio boombox, bathroom audio and this

[@vladmatei999]

Hey! Great video, altough there are some thing I want to point out that might improve your project. You should have left the polyfill inside, as it keeps the sound from bouncing off the walls. Also, the battery is pretty big, so adding even more polyfill will restore the speaker to it's tuning frequency and give you lower bass. You should have at least checked that the crossover filter has the same frequency as the original one. And you should absolutely make sure that the whole thing is airtight, so add some foam seals on that back door. Other ideeas might also include a bluetooth receiver or an Arduino so that you can play music from an USB drive and some volume controls. Oh, and that speaker seems underpowered, I would have used a bigger amp, especially since most amps distort really bad at max volume. Other than that, great project! I know sound quality is not the primary goal, but this are just some simple stuff you could do that help improve it.

[@hazelpedemonte4464]

Nice! These kinds of videos are the reason why I watch this channel. It's always interesting to see something get modified or created to do something even better!

[@melissacoleman9633]

Great job Scott. I built something simular 2 years ago for work using water proof speakers and a Bluetooth 45x2 linear off ebay and a old broken 12.8v battery pack.

[@dumitruene402]

You, my friend, are really great! I am very far from understanding electronics, but your videos are just so pleasent and good made so they make me watch them untill the end without any skips. I love your work and thank you for trying to teach us and not just make a channel that shows ranfom projects with no explanations. You are amazing man!

[@mupschiplayz1802]

Hello Great Scott, it's a great coincidence that I had exactly the same project a day ago even the brands of the boxes were the same

Really enjoy your series of videos! I need to start watching your electronic videos so I can finally do something like this one day. Keep them coming please!

[@xyaz_]

It was a really great build and I use it almost every day thanks for posting this

[@cbr7170]

Funny, I actually created the exact same thing, but with both bookshelf speakers glued together and a 50+50W Stereo Bluetooth Amp. I actually used the same handle as you did (I thought that was a creative idea). And now I see your video. Great job haha

[@tybotti]

I think you did a wonderful job on that. In the interest of keeping the size down, I use a monophonic set up with the whole cabinet, devoted to a single isobaric set up with double woofers bolted face to face, wired out of phase, in a half size cabinet.

[@EarlGray_kd7sjt]

[@MAMDAVEM]

Nice project. A tip for cutting straight lines with a jigsaw is to use both hands, one on the front and one on the handle. When you only use one hand you put sideways pressure which causes the blade to wander off the line.

[@PyroTronix]

Awsome loud speaker!

[@johnschneede]

Hey Great Scott, I think you may tune this circuit up by ensure proper cooling of the amplifier IC. I don't think it's heat dissipation is high enough to handle such occuring heat, when the speaker is used at a high Volume e.g. for a party. But beside my tipp, the project is awesome. I estimated that you would integrate a possibility for solar charging of the Speaker, maybe for a festival or so. Keep the good work going - Greatings from Germany!

[@mahmoudkortas]

great video as usual

[@telmo49]

KZbin should have a love button

[@208414]

Cool project.

[@emilracovita8421]

The project is awesome, but some inside mounted hinges would look better •_•

[@user-ur9qq8us4y]

Emil Racovita or Just 3d-printed hinges

[@Wilson84KS]

I don't get why using hinges at all if everything inside is glued with strong glue so it will break if you try to get it out, and all connections are soldered. I'm screwing everything together without any toolless "service openings" but still use plugs and also screw down the pcb's, so in case something is wrong I can take everything apart easily. Anyway a good project.

[@mat-bh]

Wilson well pointed

[@robertcartier5088]

tim you said: "Emil Racovita or Just 3d-printed hinges" LOL Sure! Let's all buy an expensive 3D printer, the pinnacle of hobby geekness, to print out something we've been making quite well for over 3500 years! Reality check: Your local hardware store has better looking hinges for a buck or two... Go ahead. Treat yourself to the real thing! ;-) Just kidding! (...and a little jealous)

[@ClydeShaffer]

You can get a decent 3D printer for less than $200 dollars these days, it's well worth it to have one around these days if you're into projects like this! Between affordable printers and an abundance of free software and tutorials, it's never been a better time to add FDM to your arsenal.

[@dushyantverma8890]

Wow your friends are amazing

[@erikburleson3131]

awesome videos!

[@officialnickname]

Another great build! I really like the way you explain the circuits. It‘s not too detailed to watch but also enough information to follow along, if you feel like it. One thing, that I noticed in your videos: You tend to emphasize the e when you say „the“. Saying it without that emphasis (like „thö“) would sound a lot more natural :)

i thought you are going to play your "favourite song" "1 kiloherz sinewave" xd. super cooll video! keep doing so!

[@randomodbuild]

I have a great idea for the next diy or buy series. Make a network patch panel toner. The kind used to locate where cables are by putting a frequency through them and having another part detect them. They cost a lot but I'm sure you can make one.

[@antoniofossaluzza1642]

Why not try sealing the panel opening and why not put the rockwool back in its place, at least you would have damaged less the speaker acoustics that were very carefully engineered

[@Engineer9736]

How do you know the original speaker was carefully designed? You have researched the specific brand and model or so? There is plenty of audio equipment that was only made to look like audio equipment, without too much engineering in the design. But yes.. Putting the rockwool back is a good idea.
