HI, I am looking for someone who is able to design and make prototypes of a pcb for an ecig like the product. Deliverables from this project would be:
- Sematic
- Pcb files for mass production
- Part manifest with all parts and estimated cost in quantity
- Documentation on how android and ios apps can control pcb for all the required controls.
- 5 prototype boards.
Pcb Electronics Requirements:
• the power source is 1 cr123a batteries at 3.7v
• Pbc size 17 by 33mm.
• Output to heating element needs 0.6-0.9Ω ≤5V
o Should heat up and stay hot for about 30 seconds. I should be able to change the heat up time and time it says hot for with the controls.
• Bluetooth LOE controls
• Controls:
o There should be a screen something like Resolution 64*32 Module outline (W x HxD) 14.5 x
8.6 × 1.2 (mm) Active area (WxH) 11.8 × 5.58 (mm) View area 12.58*6.98
This is an example image of on-screen controls.
The button there could be 4 bars at the button for battery indication. As it gets lower
changes color
• 100% - white or green
• 75% - yellow
• 50% - orange
• 25% - red
The background could change status with what is happening.
• Stand bye – white or black
• Heating- red
• Ready- Green
In the center, there is the temperature that the user as a set. They should be able
to change from C to F.
o The main control is a button that can turn left, right and push in.
Left/ Right: Decrease and increase temperature.
Push in: enter
Push and hold for 5 seconds: on/off.
o USB-C Charging Port.
Please review the app for all the features the app Bluetooth will need to give controls.
Some are :
- Start heating up
- See status
- See battery status
- Set group mode ( it stay some heating so it doenst cool down between people)

Hello,
I am Anthony from Sri Lanka. I have multiple degrees in Electronic and Mechanical Engineering. And also posses a degree in Applied Sciences.
Relevant Skills and Experience
I have many years of experience with embedded systems and electronics. I have good PCB printing facility so the prototypes will be made in my lab.
Proposed Milestones
$2000 USD - Final
Can we change the battery ?
