I'm working on a prototype for a project and I need to source a circular LCD/OLED (or similar) countdown display timer - see the attached rough sketch.
The timer must only countdown days automatically, not hours, minutes or seconds, and be operated by a battery that you would get in a digital wristwatch or car key fob. It needs to be simple and basic in its functionality. If I want to set the timer to countdown from 10 days then I push the + button until I get to 10 and if I leave it for 3 seconds it will set on this number. It only requires 3 digits so the max number of days is 999. When the timer reaches 3 days the display changes colour from green to yellow and when it reaches 0 days it changes from yellow to red and flashes. When it goes past zero the next day should be -1, then -2, etc.
1. Size - it should be 1.5 inches diameter, 2 inches max, and as thin as possible.
2. It must be touch screen – see the video of an air fryer – this is much the same concept as what I want but smaller and thinner and battery operated.
3. The screen will need a thin plastic or rubber transparent cover to protect it from water but at the same time, this should not impact its visibility or functionality of the +/- buttons.
The product delivered must be fully complete with screen, battery and functionality.
- If you cannot do this job from beginning to end then do not apply.
- If you need to purchase items/parts then you must tell me exactly what is needed and the cost.
- If you agree a time frame then you must stick to this and not be sidetracked by other projects.
- If you believe you can do this job and have previous experience then I need to see copies of your work.
