Visions for the future or better, presence: the drone-postman ?

Matternet has started, as promised. That's a remarkable milestone.

In combination with a yellow, not red :), box. Letters of up to 1.000 gr / 20 = 50 standard letters (and a additional USB-stick (~30 gr)) will soon replace mail delivery in subsaharan regions and other emerging regions. - This will combine physical delivery and data mule transport for information kiosks. - Satellites, loon and such thing will not be needed @ the moment. - Ok, it's a vision. But: who knows?

pimail.project: challenges

oh yes. there more diggin in net, the more challenges...

so: main problem is sustainable power supply, we cannot imagine in europe, in 220V there are pikes of 1000 Volts. This will destroy everything.

So only buffered solar power will be an adequate solution. 12 V, PC and screen!

Also SDCard is destroyed after 6-8 month of 24/365 working. Therefore all data and operations will be performed from external usb harddisk. I decided: 500 Gigabyte. SATA in an external casing. berryboot will help perfect!

Next challenge will be: starting Raspberry Pi ,  because of energetic aspects, this gadget will be ideal. But not operating from SD-card.

i continue digging now

Ckeditor.com in combination with Raspberry Pi 2 Model B works fine!

pimail scheme of data mule

MULE must not be a mule of course :) - it could be a car, a motocycle, a bycicle, a smartphone, a plane, a rocket, everything....

completely outdated: DakNet calculations

those calculations, done yrs ago, are totally outdated today.

500 USD Motorcycle has been nonsense, totally.

Hub Wireless Interface & Antenna: €70  = 75 $ x 1      075
Mobile Access point & Antenna: € 70    = 75 $  x 2     150

Kiosk Wireless & Antenna: € 70            = 75 $  x 12   900
------------------------------------------------------------------------------------
total Capex:                                               1125 $ + motorcycle 2125 $

compare this to 5900 $

price today is <<  -50 %

VIDEO: Live-Demo Part 3 - How to convert 32GB Raspberry Pi 2 - whezzy - into a standalone WiFi Hotspot (REALTEK / EDIMAX)

This is Part 3: The last steps  - We use a fresh 32GB card with raspbian whezzy.

https://docs.google.com/document/d/16hJS7fnPyKUwbvR33_nMku_b6XcYaBJXVpeCIMoJzcQ/edit?usp=sharing

Those steps are done there:

we forgott this in Part II :( and correct it . Such things happen in real life!

sudo nano /etc/network/interfaces

iface wlan0 inet static

address 10.10.10.10

netmask 255.255.255.0

#iface wlan0 inet manual

#wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf

#iface default inet dhcp

This is Part 2: Making the AP (15 Min) - We use a fresh 32GB card with whezzy installed on..

https://docs.google.com/document/d/16hJS7fnPyKUwbvR33_nMku_b6XcYaBJXVpeCIMoJzcQ/edit?usp=sharing
