Hacking a Logitech MK220 wireless keyboard and mouse combo for a community computer

These involve creating an easy to carry box with projector, computer, speakers and wirless keyboard/mouse all stuffed in. After building one based around Intel NUC PC I decided to think of ways of decreasing cost of the Community Computers and make it more user friendly for our not so tech savvy teachers. Towards that, I thought of using an old non-HDMI VGA projector paired with a Single Board Computer APC 8750 which runs Android OS and has a VGA video output which makes pairing with an old projector possible..

Since these PCs only have and HDMI output, I would need an HDMI capable projector. So I asked my friends for donations and went shopping and bought these:
BenQ MS521p [Cheapest HDMI Projector]
INR 30,000Intel DN2820FYKH [NUC PC]
INR 9,3408GB Low Voltage 1.35V SODIMM DDR3 RAM Kingston KVR16LS11/8 [For…
