Wireless Powered Thunder-Safe (overvoltage protected) NAS Backup System
The Problem:
Since documents, paper, photos, etc. became digital, it is required to have a backup of the digital data. Thunders can distroy computers and hard disks connected via USB or Ethernet. Saving data in the cloud is one possibility but vulnerable by hackers via the internet. With a server at home the risk is high an overvoltage or thunders are destroying the hardware and the stored data.
The Solution:
The general idea is to attach the NAS by WIFI to disconnect the wired connected Ethernet. But the power delivery causes in some problems, but can we solved with the Wireless Powerkit of Futura Electronica. The Wireless Power Kit includes an FT1235 5W transmitter and an FT1236 5W receiver.
While the NAS functionality is needing more power than the 5W the Wireless Power Kit can offer, a battery will be charged additionally providing an USV functionallity during backup operation. The NAS functionality itself will only be turned on periodically or by some wake-up functionality realized by a low power MCU with low power WLAN.
