Backlit 4 digit LCD timer module Seale
Required skills: CAD/CAM, Electronics, Microcontroller, PCB Layout
Description
I would like a 4 digit, backlit LCD timer module with a magnetic reed switch. Maximum module size is 50mmx30mmx20mm please. This module including batteries must be as cheap as possible, USD4 maximum cost as this is intended to be disposable after a few weeks use.
The LCD display must be 4 digits and backlit. Blue backlight preferred but not essential. I can provide you with a supplier for this part however I would like to see what you are able to find and at what price. Happy for you to use 2 PCBs if you wish, so that the battery PCB can sit behind the LCD PCB. This may help you fit the dimensions, but I am also interested in your ideas. The switch is a 10mm magnetic reed switch (AO) and is securely connected to the back of the module on its lowest edge by a 200mm wire (clear sheath) with the reed switch at the furtherest point.
The PCB dimension flexibility: (50mm +/- 2mm) x (30mm +/- 10mm) x (30mm +/- 15mm)
Function:
When the reed switch is activated the timer LCD screen lights up and counts up in seconds (max 99.99 seconds- ss:th). Accuracy is not important. +-5% is ok. Whole second digits are only visible when counted (I don't want "00.01", the visible digits must be " .01"). Once the timer is deactivated the time continues to be displayed for ~20 seconds. After 20 seconds the power shuts off and the screen goes blank. Upon activation it resets and begins counting up again from .01.
If the timer is interrupted while the LCD is in operation (either counting or displaying the previous count) the module resets and begins counting up again from .01. The timer must enable this interruption.
For example the reed switch has a magnet placed near it, causing it to close. The timer then activates and starts counting up from .01. As the timer is counting the magnet moves away, causing the reed switch to open and break the circuit. The timer pauses counting and displays the time for 20.00 seconds. After 20secs the timer powers down, waiting for the magnet to pass the reed switch again. If the magnet passes the reed switch at any time during the 20sec display time, the timer will begin counting from .01.
This timer needs 14 hours of operation time. Standby time should be as long as possible (months). Lithium coin batteries and clips are one power option because of cost and size, however if other battery options would also deliver to requirement and low cost I am open to ideas.
I have gerber and hex files if you need them however this request differs slightly from the files I have so some work will be needed. Can be provided though.
I want 15 examples of this timer, as well as all supporting documentation. The supporting documentation will be complete and will enable manufacture with no uncertainties. If your design and prototypes are suitable in cost and quality I will definitely be interested in a supplier relationship.
I am happy to release a milestone payment after agreement of design and components, with full payment upon receipt of prototypes. Your bid must include delivery costs to Sydney, Australia. Good luck guys.
