Bluetooth Speaker

hello everyone, probably you know the problems when you go to a party of a friend or someone else, and they don't have a normal speaker setup, so some come with a very small speaker with not much power.

well here i made a difference for those party's, i made the speaker easy controllable with an bluetooth 4.0 board and a small amplifier that belongs into a scooter, also the speakers on the photo's are originally placed into a car but i wanted to use them for this project.

to make a speaker you need the right parts of course, so here a list of the parts i used to make this project happening:

• speakers (car coaxial speakers) http://2004.mtxaudio.eu/spip.php?article1312
• amplifier 12v (mine is not available but for this project you need at least a 4ohm 35 w sms per channel amp
• battery 12v http://store.accusafe.nl/voeding/accu-s/csb-loodg...
• bluetooth receiver 12v http://www.ebay.nl/itm/ricevitore-audio-BLUETOOTH-...
• accusafe 12v http://store.accusafe.nl/modules/accu-bewaking/acc...
• speaker wires
• industrial power cable
• mdf
• handles for the sides
• 12v power supply https://nl.aliexpress.com/item/60W-Switching-Switc..
• iron plate for connecting the electronics
• volume pot 500 kOhm
• 3 pin switch bluetooth-neutral-aux https://nl.aliexpress.com/item/2016-Brand-New-1PCS...
• voltmeter https://nl.aliexpress.com/item/DC-4-5-150V-0-56-Re...
• aux port http://www.ebay.nl/itm/190731515793?_trksid=p20603...
• on off switch https://nl.aliexpress.com/item/New-10Pcs-lot-2-Pin...https://nl.aliexpress.com/item/2015-Hot-5-Pcs-3P-I...

it is really up to yourself what you are gonna use, i got some of the parts for a very good deal like the bluetooth receiver, only that one timely not available, i will put an link when its for sale again.

if you look at the electronics i decided to make a switch between aux input and bluetooth input, when people try to decide to put annoying music on bluetooth you simply flip the switch to aux and you have no problems with the bad music anymore ;)

it starts from top left, there is the 230v input, and then goes to a battery charger and power supply, the battery charger of mine is not included bc mine broke down somehow.

now the wires from the 230v input go to the accusafe, it is an easy made security unit that controls the power.

it has 4 ports, one for power supply input, one for charger, one for the battery and one out put to your amplifier.

this control unit works on 12v so its important that every power unit is 12v that goes into the accusafe, it also cannot hold anything above the 8 A. everything i used is ok to connect it to.

if anyone doesn't understand the sketch, just ask me ;)

i don't got the chance take enough pictures to show how to make the panels and further, but i hope i brought the idea to your mind so you can use your imagination to make this project even better at your home :)

it wasn't my intention to share every piece of woodwork/ vinyl, but i just wanted to share the electronic schedule and the results what i made from it, thanks for looking into this.

anyone got questions, ask them :)
