Spring has sprung and I've had the board at the wake park a few times.. it rocks! :thumb:

Had a small issue with bluetooth losing connection when the phone is submerged - turns out bluetooth does not have much range under water :o
Time for an upgrade!

Got another JBL Go2, and printed a bracket to hold two of these.
Bought a cheap ($3) mp3 player and siliconed it into the bracket to make it waterproof.
I upgraded the mp3 player battery (to 5 hours play time to match the JBLs) and moved the usb charger and battery outside of the player to make charging easier.
And then ran two audio cables to the JBLs to provide stereo playback.

I've used the mono one as much off the water as on, and with the stereo setup it's going to be even sweeter 8)

You just infused a block of corecell foam with resin? Wtf?

Corecell needs skimming with resin/glass bubbles first so it doesn’t absorb a ton of weight before you laminate it

Or you end up with a heavy core and a poor bond to the laminate.

I use Gurit Corecell M, which has very low resin absorption. Perhaps you are thinking of another foam (open-cell?)..

Strange how we could have such different experiences then :-)
