The USB Tester Board Part 2

The assembly for the USB Tester Board begins today. I managed to aligned all of the components except the 100k ohm where I discovered that I only have 5 pieces instead of 20 pcs. This means that I have to go to SS2 again to buy the part sometime this week. After rearrange the components, unfortunately not according to the layout as proposed earlier since I found out that its better to change due to space constraint on the actual PCB. The wiring would be completed once I get the 100k ohm resistors. This is how the new layout looks like.

As for the USB black box, today I also managed to connect all ports A, B, C from 3 X 10pins to 40IDC. So what left is to check with the written software that I did couple weeks ago. This is how it looks like once all the connectors inside are plugged in. As you can see I only do for one of the USB board since I planned to use the other for 8255 upgrade. As the IBM Thinkpad is with Mr Khow for him to study C programming, I will continue with the hardware fabrication.

Give short briefing regarding the Borland Turbo C programming method to Mr Khow. Show him how the program works as well as setting up the PC and Thinkpad for programming training. Mr Yu also brief him the basic of PC interfacing using the 8255 PPI board.

Meanwhile Mr Yu TT request to go ahead with the Robot project while waiting for Mr Khow to learn C. So he asked to get the quotation for required items such as servo motor from Vanguard as well as aluminum from Sg Besi. If possible he wants it to be available by Wednesday so that the work can be carried out to built the robot after holiday, end of this month. The priority now is to built the robot, then followed by Mooncake slider with pneumatic pusher. As for the pusher, the control would be hardwire rather than exclusive electronic control.
