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:
- Drill small hole in node enclosure against LED location
- Cover it from outside with masking tape
- Put some amount of hot glue from the inside to cover the hole, wait till glue hardens, remove masking tape. And voila!!
