The beginning of the hardwares assembly...

USB Board Housing
A black harden plastic box sizing 160x95x50mm is used to housed 2 USB 24 I/O mk3 boards. Now those two USB's are placed inside the box already which make it easier to use and safer to play with.

Tester Board
The components to built are being grouped so that later on they can be hatced or soldered into PCB. This board is very important in future usage as USB board confirmation OK incase some technical problem arised.

AC to DC Power Supply
Mr Khow is started to gather all necessary components to built the DC supply board. It is merely a 15VDC output circuit gained from an AC240V step down to 15VAC. The AC then is converted into DC using 4 pins bridge rectifier in which tied to 2200uF 35V electrolytic capacitor. Next the DC passes through an IC 7815 DC regulator with 2A current limiting to smoothen it that coupled with 2 ceramic 100nF capacitor. Here is the built circuit diagram.
Once the circuit is fully assembled, then it will be tested against 15VDC Motor.
