The purpose of this blog is to give the lay person an insight into the practical work involved in this project as it progresses through various developmental phases. It will be updated regularly although slightly behind the actual project development.
 
This first entry details setting up a bench top prototype of the system
 
objective 1

-Prepare prototyping area
-Develop Rx and Tx onto breadboard for both systems
38kHz(TSOP2438 + TSAL7400)
455KHz(TSOP7000 + QED222)
*Include transistor modulation on Emitter to enable PWM via mod source (check 2N2138 spec upto 455kHz slew-rate)
Bunched up RxTx: from left to right device ID
38kHz system: TSAL7400 (clear),TSU540 (purple), TS2438Rx @ 940nm
455kHz system: QED222, TSOP7000rx @ 880nm
Result - built 5 modules, and connections

-Test one way comms from one Uc to another. Determine the maximum bandwidth
-Try firstly modulated UART (modulation via signal generator)
-Write a program to send random data out of the UART once a second
-the program should allow baud rate to be changed easily to check max bandwidth
-Write a program that will try to receive this data.

-Tested at 38kHz WUART transmission (working)
-TSAL7400 -better spacial dispersion
-TSU540-working
