Circuit for Pump
Phase 2
Board Design
Board Ordered
Feature/Function Review
Below is the complete picture that includes elements of all 3 phases.
Qualities needed in Freelancer:
1. Understands that scheduling is important. —> If you can’t make a meeting, propose new times, and continue to follow up until the meeting happens, we won't work well together. Be aware of my timezone and availability.
2. Communicates well —> Provides daily updates (mandatory), provides an easy to follow plan of where we are in relation to completing the project (big picture) and the task (small picture) as well as what’s left and the amount of time needed for each. Great english is mandatory. If I need to talk, they don’t brush me off.
3. Respectful of time —> Does not take days to respond to an email or text message. Has access to a strong communications infrastructure.—> I know we don’t have flying cars yet or teleporters, but if you’re in this line of work you should at least have very stable internet connection (…barring any natural disaster)
4. Freelancer to provide meeting minutes (template to be provided).
5. I cannot work with someone who passively stalls. I need someone who gets it done. I will not work with someone who is trying to play "hot potato tennis” or phone tag. I need the work done.
Work/Project expectations:
-Daily updates are mandatory
-Confirm primary methods and applications for communication (WhatsApp, Skype, etc.)
-Confirm communication infrastructure strength.
-Provide meeting minutes based on template (to be provided upon acceptance of job)
-Feedback will be left after the circuit is assembled and tested
-If not response is received from me in 12 hours follow up with an additional phone call
Circuit
The circuit to be created needs to operate and/or respond to pressure sensors and input and perform the below:
operate a pump
operate release valve
LED lights
respond to BlueTooth commands and capture data via BT
capture logs and transmit via BT of all activity
show Power levels and transmit via BT
respond to Sensor information
operate Pressure release valves
[All main features, even if not mentioned above, will be blue tooth accessible]
Additional features of the device will be:
Bluetooth (BT) enabled
It needs to be rechargeable via USB port.
Green LED indicates completely charged
Flashing blue light when recharge is needed
Quick Start feature starts designated default program
Log of all activity is captured and able to be transferred via BT
Pressure sensors (range of levels)
Release valves (2)
NOTE: LEDs are not built into the board, but wired and able to be positioned.
The circuit needs to be compact and as sleek/streamlined as possible. It can’t have inductors and resistors sticking up in random places. Smooth it out. Make it look professional not like a science project.
Deliverables:
Signed NDA
PCB BOM with all supporting components
Component selection list in spreadsheet format (with costs, adapters, batteries, battery connectors, all components to make the device work.)
Gerber files for fabrication
Manufacture files created
Layout design & Gerber generation for PCB fabrication
CAD Files
Predetermined run programs to be provided upon acceptance of the project.
Additional features:
-Pressing the power button and holding it for 3 seconds stops any activity and returns motors to home position.
-Pressing the power button and holding it for 1 second starts a preset (once it’s programmed)
-When off, motors return to home position.
-All motors and physical functions will be controlled via bluetooth
-All logs captured will be sent and captured via blue tooth.
Testing
_________
Battery - full run to completely dead
Recharge - Recharge time from completely dead to fully charged
Pump -
BT - Signals (encrypted) for all input described above can be sent/received
Data - Formatting/content (encrypted) for all input described above can be sent/received
