We invite bids for the design of a simple battery powered electronics device with an alarm. The work we are looking for includes: Schematic design component specification (BOM) PCB layout (optional) Device description: Battery powered Motion sensor with audible alarm. When the device is moved an audible alarm will sound. The design should include a switch to activate the device. Single press to the switch turns the device on which then becomes active after a delay of 2 or 3 seconds. A long press on the switch turns the device off. Component cost is a primary concern, followed closely by reliability. Design shall become copyright of purchaser.
