2018/05/10: er zit een web-page op (http://10.42.45.122/) die vertelt wanneer de laatste bliksem was en de afstand ook. ook doet-ie mdns dus je moet 'm kunnen vinden zonder dhcp-inzage
Wat is het
Laten we blikseminslagen in een omtrek van 40km op een of andere manier zichtbaar maken in de space.
Dat op basis van een AS3935 sensor. Flok koopt 'm en soldeert er een Wemos D1 aan vast en doet er mqtt software op.

New source code: bliksem on github
Features:
- hardware is configured in SPI mode
- uses sparkfun AS3935 library
- AS3935 is used with default settings, we add some extra detection for spurious lightning:
- ignore anything but the lightning interrupt (chip/library still triggers spurious interrupts from time to time)
- distance has to be > 1 km, energy has to be > 0
- syncs time using NTP
- publishes on MQTT as a simple JSON message:
- status topic "revspace/sensors/bliksem/<chipid>/status": can be "online" or "offline"
- value topic "revspace/sensors/bliksem/<chipid>/bliksem": contains a JSON string of the most recent detection, e.g. {"time":1566721631,"distance":8,"energy":44229}
