We invite bids for the design of a simple battery powered electronics device with an alarm.
The work we are looking for includes:
component specification (BOM)
PCB layout (optional)
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.

I work in an embedded R&D center in electronics. I have an experience of over 5 years in drawing schematics and artwork. I have done a similar project in the past hence i think i can deliver the prototype on time.
Sir, I just completed my engg [url removed, login to view] my project was motion detector. So iam familiar with the circuit design and the problems involved in manufacturing. Also please go through my private message.
I will do it very cheaply , with simple hardware design , I even may not use a micro-controller , It will be simple hardware design . I'm very great at hardware /electronics. Lets starts.
approx 4 year experience of electronic circuit design. Have experience of Designing such alarming system like burglar alarm ,liquid level and over-temperature alarm system.
