ABS-Boost (waterproof casing) for the Adafruit MintyBoost!
Check out this awesome waterproof MintyBoost enclosure project built by Adafruit community member “IthinkIunderstand” on the Adafruit Forums!
Just thought i would share my first MintyBoost kit. I do a lot of biking and hiking and wanted something a little more rugged than the standard metal case. So i dug out the plumbing fittings and made a nice little waterproof version. Of course, we always realize a better way to build something AFTER we’ve built the first one. If i were to do this again, i would have a cable directly soldered to the board and coming out of a waterproof grommet somewhere on the cylinder. I would leave enough of the cable inside so that changing the batteries would simply mean unscrewing the cap and sliding out the unit, batteries first, and switching out the double A’s. That way you could just plug it in without opening it up.
This thing is made with 1 1/2 inch plumbing pieces which is common in any hardware store. The pictures are deceiving, but the length is roughly 135mm or 5 1/4 inches. If i had changed the size of the Lexan the batteries and board are sitting on i might have been able to add a set of spare batteries inside as a backup. This thing could be made to fit inside a 1 1/4inch pipe also, but it would be tight.
Another version of this would be to put it inside a plastic case for outdoor electrical. There would be room for a lipo battery and the charging circuit, including something solar. Look in the section where they keep all that gray plastic electrical conduit stuff.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

With that much air volume, it almost certainly floats too. So you could use it around boats.
