On Tuesday we met with Navid to follow up with the progress of our project. The following were discussion in the meeting :

– Address certain issues regarding about the PCB. Navid suggested that we the connector to connect all the inputs and outputs to the Adruino instead of the ATMega chip because instability and noise from the surrounding may raise concerns with the signals transmitted between the micro controller chip and the other parts of the circuit.

– To have both parts ( Main PCB and LCD PCB) to be designed on the same PCB board.

– Heat sink for power regulator- In case of too much heat dissipation due to high power, a small metal piece may be considered to be added behind the voltage regulator chip. Current has to be measured to know the power dissipated.

-Traces on the PCB to have minimum clearance of 0.4mm.

-Holes to be at least 1mm and pads to be 2mm.

We have also screwed both (top and bottom) layers of the platform.

On Friday, WengFei has scheduled with Navid to go through the PCB design again before sending it off for fabrication. Minor changes to the circuit has done and has been finalized by the end of the day.

On Saturday, PCB was ordered and the designed was sent to 3PCB in China for fabrication. The manufacturing of the PCB will take about 2-3 days and an additional few days for shipping.
