Just coming back from Las Vegas, US. Sorry for no weekly update 
Power Bank:
Getting this power bank few day ago. It look quite solid and nice. Took me more then 7hour to fully charged this power bank with 2A 5V adapter.
Look like the power indicated is correct for 10400mah capacity. This also mean the battery is original 
.
Few reason for choosing this power bank for this project. First is their capacity with 10400mah it enough to run 2A 5V at lease 4hour.
Second is the price with SGD$14, I don't think your can get other better then this and the last one is their function that able to working while charging.
This picture show the complete set for the power bank. They not come with charger.
Next is the important testing for the power bank that related with this project. The test include output power test to support the project hardware and charging function while the output running.
This helpful for the project mean that I don't need to build another step up converter to running the hardware. It can be tap directly powered from the power bank because it work all the time while charging or not.
Picture show the power bank still working to charging my Ipad/Iphone while it in charging mode.
Maybe I should upload better picture to explain or show this function . Let me know if require.
PCB:
This is version 4 for the PCB. Almost all the hardware been put together and some wrong measurement for hardware been corrected.
80 pin connector been share and same go to BBB. Additional 12 pin for BBB can be connected by hard wire. Thinking this should be more then enough.
Next should be the CC3200 and LCD. Maybe will do this in the merge work at CAM side or just wire up.
Picture show the updated 2 layer PCB design for the BBB, fan, dust sensor and connector.
Attached picture show the CAM for merge PCB. Look good just some minor issue with overlap hole
Now just hope the manufacture can make it with small spacing gap 
.
But for sure our prototype machine cannot make it 
CAM Editing:
Having some issue with the CC3200 drill file. Look like some of the drill hole is not align with the pad. Any idea everyone?
Picture show there are missing drill hole at the right side of the header and place at the left side of the PCB.
Still in Jetlag mode
