synopsis
Need to fill this with text when I have time..
Basic ingredients:
- sturdy compact waterproof (ammo) box
- battery, initially 7Ah (ordered)
- Fritz!Box router (NAT, FxS, FxO, DECT)
- Raspberry Pi running FreeSWITCH and DHCP
- Raspberry Pi running FreeSWITCH and TFTP
- (PoE) ethernet switch (ordered)
- Efficient power converter(s)
prototyping
Tested the following items:
- Two Raspberry Pis on a drill battery pack (step-down)
- uses 0.33A at approximately 12V
- Cisco CP7940 on a drill battery pack
- uses something between 0.36A and 0.45A at approximately 12V
- Fritz!box has a switching regulator to 5V tested between 5.5V and 15V (drops off at 5.3V idle and elca at power supply segment is rated 16V)
- without WiFi, it peaks at 0.44A (12V), and idles at about 0.34A-0.38, which the webservice is saying 41%-43%, which means it would top at about 0.88A.
- With 15V power it idles at about 0.25A
Still to test/measure:
- PoE switch at 48v
- whole set with battery and battery charger
