Visible Light Communications

My experiments with Visible Light Communication can be found here. Most of the circuit components are selected according to their easy availability in my geographical area without spending too much on shipping (seriously a photodiode from Digikey is 1.5 USD + 60 USD shipping !!! ).

All of this can act as a reference for someone in designing a VLC system or atleast act as a guide on how to evaluate sensors etc. Of course sensors may vary but the workflow would somewhat remain the same...

Stage I
Stage One is all about figuring out if i have the right sensors for the job. A sensor with fast rise and fall times and a fast MOSFET based LED driver. Level: Basic

 Stage II
