DIY LED lens

APL2017 last edited by
For my battery powered water leak nodes I wanted to add a clear lens to be able to see communication LED status on Arduino Pro Mini while maintaining reasonable water protection. The quick no cost solution was:
1. Drill small hole in node enclosure against LED location
2. Cover it from outside with masking tape
3. Put some amount of hot glue from the inside to cover the hole, wait till glue hardens, remove masking tape. And voila!!

@Kokosnoot good solution. I remember the discussion in the early days of MySensors. I've powered the radio's for most of my sensors from the 3.3v regulator on the arduino board and for me that works perfect. But for my latest designs I decided to add a separate ams regulator for my radio's like the guys suggested in the beginning. Because you basically want the on board regulator to power the mcu only.
