On Tuesday, we met with Navid to inform him our progress:

– The PCB has been send for fabrication.

-Some suggestions regarding how to assemble the PCB were given.

• Solder the PCB parts by parts
• test if there is short circuit between ground and vcc
• put the ICs after
• it’s better to use socket than soldering the ICs directly to PCB

On the same day, we discussed our storyboard and decided the basic idea how we are going to film our video, and also decided the questions we are going to ask our client during filming.

On Thursday, we obtained the legs for our platform, and we then started to design our ramp with a height of 8.5 cm. After discuss with Mark, some designed techniques were given. Therefore, we designed the ramp with three right triangles as a stand, and a piece of a wood on top of its hypotenuse. It reduced the weight and the material used.

On the same day, we went to Lee’s Electronic after our short meeting at school. We purchased the following items:

• plastic box for our circuitry
• socket for LCD, regulator, and INA
• Arduino prtotosheild
• Solder iron
