Alright then. here's my plan of action for the next weeks.
I will start looking for some waterproof containers.
Idea: Salt shakers!
- Lots of sizes to choose from
- Screw-on cap essentially waterproof, yet easy to open
- Bonus: Holes for the cables ;D sealable with silicone
I'll hold off the purchase until I have decided what batteries and charger circuit I will need.
I will also try some new button designs.
The LED Matrix, Arduino (probably a Pro Mini @5V), batteries and charger will have to wait to about mid-October due to exams, and other projects. Just to let you know, if I'm not active on this topic in the next few weeks, it doesn't mean the project's abandoned!
I'll keep you posted.
