How to build your own KasaDaka

The KasaDaka is assembled from low-cost components, here is a list of what you need and a link to an on-line shopping option :

• One RaspberryPi 2 model B (https://www.pi-supply.com/product/raspberry-pi-2-model-b-newest-version/)
• A pocket display (http://www.watterott.com/en/RPi-Display-B-Plus or http://www.amazon.co.uk/gp/product/B00OFLKPG4)
• A Pi-Juice module and battery pack with a solar panel to charge it (https://www.pijuice.com/product/pijuice-solar/)
• A casing big enough to pack the battery pack and the screen (https://www.pi-supply.com/product/short-crust-plus-perfect-base-raspberry-pi-b-plus/)
• A camera module (https://www.pi-supply.com/product/raspberry-pi-camera-board-v1-3-5mp-1080p/)
• A wifi adapter that supports the 802.11s Mesh mode (https://www.conrad.nl/nl/tp-link-tl-wn722n-wifi-stick-150-mbits-995624.html)
• A USB 3G dongle compatible with Chan-dongle (http://www.mifi-3g-wifi.nl/3g/4g-mifi-routers-en-modems/huawei-k3520-3g-modem-usb-dongel)
• A flexible power-supply adapter in case there is not enough sun (https://www.pi-supply.com/product/12v-3a-power-supply-with-international-plugs/)

All that amount for a bit less than 280 euros (the most expensive bit is the battery+solar panel pack).
