Visaton FR 8 JS bluetooth speaker

thingiverse

A simple bluetooth speaker. I used the following components: - [TDA7492P 2x25W Audio Amplifier with bluetooth 4.0](https://www.tinytronics.nl/shop/nl/audio/versterkers/tda7492p-2x25w-audio-versterker-met-bluetooth-4.0) - [3x 18650 battery holder ( 12.6 Volts )](https://www.tinytronics.nl/shop/nl/batterij-en-accu/3x-18650-batterij-houder-met-losse-draden) - [3S BMS circuit board](https://www.tinytronics.nl/shop/nl/batterij-en-accu/overige/li-ion-li-po-protectiecircuit-(bms)-3s-1) - [3x 18650 battery](https://www.tinytronics.nl/shop/nl/batterij-en-accu/18650/panasonic-18650-li-ion-batterij-3350mah-6.7a-ncr18650b) - [DC jack 5.5mm for 12mm hole](https://www.tinytronics.nl/shop/nl/connectoren/jack-pluggen/dc-jack-plastic-5.5mm-female-mount) - [8.5 x 13.5mm on/off switch](https://www.tinytronics.nl/shop/nl/componenten/schakelaars/standaard-inbouw-wipschakelaar-klein) - [Visaton FR 8 JS speakers](https://www.visaton.de/en/products/fullrange-systems/fr-8-js-8-ohm) All of the above links link to a Dutch electronics site. If you want to wait for months and pay less, you'll find the same stuff on aliexpres, eBay , etc. All the electronic parts fit in the back cover, I hot-snotted all the parts to the back. I also used hot-snot to seal the holes for the speaker cables. After fitting the speakers and electronics, glue all pieces together with hot-snot or use some other glue that glues PLA. You'll need a [12.6 Volt Li-ion charger](https://www.ebay.com/itm/18650-li-ion-battery-charger-12-6V-2A-electric-Self-unicycle-scooter-charger/224025159432?_trkparms=aid%3D1110006%26algo%3DHOMESPLICE.SIM%26ao%3D1%26asc%3D20200520130048%26meid%3Dacfa1f82fdfd4d4f8389c4cfb01f5928%26pid%3D100005%26rk%3D2%26rkt%3D12%26mehot%3Dpf%26sd%3D264848496617%26itm%3D224025159432%26pmt%3D1%26noa%3D0%26pg%3D2047675%26algv%3DSimplAMLv5PairwiseWebWithBBEV2bDemotion%26brand%3DUnbranded&_trksid=p2047675.c100005.m1851) to charge the thing. Once charged you don't have to worry about a re-charge for the next few weeks ;-). A more powerfull version with FRS 8 speakers is in the works ( uses a different front part )...
