Manufacture a Product for me Custom Job (Electronics)

Hello Engineers of the World

I come to you with the following exciting project:

We have a system consisting of 3 units as follows [BOM Attached - Excel File]:

Unit #1:

- Set of batteries, acting as power bank (capacity 12000 mAh or more)

- Memory chip (64 GB) - we plan to increase this later

- Bluetooth module for proximity


Unit #2:

- A parallel hub with the following ports:

- 2x USB port for power output from batteries

- 1x USB port for data output / input to the memory chip

- 1x USB mini-port for battery power input (charging)

- 1x LED indicator with following conditions:

- Green Light: if battery is plugged in and FULL

- Orange Light: if battery is charging

- Red Light (FLASH): if battery is being used and it low on current capacity or empty


Unit #3:

- LED Switch Button #1: Switch Bluetooth module On / Off

- LED Switch Button #2: Switch whole system On / Off (Screen + Battery Output + Memory Access + Bluetooth Module)

- An OLED screen (blue and white) to display the following:

- Battery status (shape of a battery + percentage)

- Status of Bluetooth module

- An ALL CAPS word in the middle saying "HELLO"


Connectivity Information:

- Units will be wire connected

- Unit 2 and Unit 3 are 10 cm away

- Unit 1 is 45cm away from Units 2 and 3. Unit #1 is the main unit, right? ;)

- Cables must be neatly done, the way engineers work


Software Information:

- System should be programmable, and ready to use. Plug and play

- For proximity, the Bluetooth module is expected to be broadcasting signal when powered on, a smart phone application will be developed (separately) to get proximity location

- We must be able to change the word "HELLO" displayed on screen



- Circuits plans + blue prints + anything needed for manufacturing

- A prototype with all 3 units built, connected and functional together



- We will make the hard material enclosures for all 3 units. If you want to make them, we will pay you a bonus. Dimensions of the enclosure and blue prints are attached to this post

- Material is hard plastic (suggest alternatives) - Color: Black



12 days. We have 12 days to show a working prototype to our management or we all get fired (A)


Update: the USB ports giving output from the batteries are expected to deliver fast charging.
