Here is my first inscrutable please provide some feedback to make the next even better !
This boombox is taking advantage of the limited space of a glove box compartment of an old scooter Yamaha Beluga 80cc (2nd Gen and re-branded by MBK).
It is power by 3 cells @3.7V extracted from an old laptop battery.
Here is the BOM :
- TPA3116 amp 15$
- Digital Voltmeter 2$
- Switch and 18650 battery holder 2$
- speakers are from a old car but you can use any 4-8 ohms speakers
V1 at the moment improvements to come :
V1.5 : Better waterproofing and cosmetic enhancements.
V2 : front panel control with remapped push buttons
V3 : PCM integration to use scooter's alternator and charger batteries.
Step 1: Mark Some Holes for the Speakers
drill holes for the sound
Step 2: Marks and Holes Again !
Make the hole with Dremel to host the switch and digital voltmeter
Used some motherboards spacers and tapped the plastic to screw them in.
Step 3: Glue Gun Time!
waterproofed the volt meter to avoid issues with humidity.
Screwed and glue gunned the 3S battery holder.
