After 6+ years of checking out everyone else's Instructables, this is my very first Instructables!
This design is also an entry for the UP contest. Enjoy.
I set out to make my own portable speaker with a similar design to the Jambox with the addition of a few extra features.
For this build you will need the following: UPDATE: Prices and links to items
Small USB-powered speakers with built in amp
portable USB charger for cellphones
Bluetooth Stereo A2DP module $25
NFC Tag $2 per tag or less
Other tools and Materials:
Soldering Iron and Accessories
small square magnets
3D printer (My school had a Replicator 2)
Screwdriver (flat and Philips)
Hot glue gun
Pry tool used for cell phones
Step 1: Disassembling the Speakers
Find some speakers that will suit your needs. Test them to make sure the output is loud enough. You might need to purchase an amp to boost the signal if necessary. The power input should be 5v to be compatible for the battery in the next step.
Split the speakers open. Most have grills on the front that are easily removable.
If the speakers are not assembled with screws then you will have to remove the plastic around the components. I took a screw driver and a pry tool to split the sides. The amp should be in the unit with the power and aux cord.
Resolder the cables back to the board if necessary. Add hot glue to the cables so they don't pull out or short circuit other components.
