For fun & profit, I will like to design a cheap "droppable" VPN server that will be placed a mile or so away from a a known wifi hotspot, where the portable device would serve as a portable vpn server on the internet.
My prototype budget is about $150 US Dollars.
I do not see this has been done before, so here my idea for your review. Your experience & knowledge would be highly appreciated. I'm thinking of selling these when I can make them more cheap. I have not built it yet so I only are in the start of prototype idea stages.
PROTOTYPE:
- RADIO.
- COMPUTER.
- POWER.
RADIO: a. Any small 12VDC wifi radio & router should work. b. Maybe the Ubiquiti NanoStation Loco M2 perhaps? c. Prototype cost is near $50 US Dollars.
COMPUTER: a. Any cheap computer board with Ethernet & USB should work. b. Maybe the Raspberry Pi Model B should work? c. Prototype cost is near $35 US Dollars.
POWER: a. Need only charges & supplies 12 volts should work. b. Maybe this Amazon 6W solar panel should work?
I have not built this yet, before I go in wrong directions, I would enjoy to ask if you have better ideas for parts to improve specifications or to keep the prototype costs down.
Your helping ideas are much welcome ahead of time!
