$25-50 USD / hour

I need a timing circuit to drive a small motor for a fixed amount of time at two preset intervals. The circuit can (but does not have to) be based around a MSOP LMC555 and other SMD components, powered by a single button 3v source. The entire circuit must fit into a small defined space, appropriate components must be selected. The controls will be membrane touch switches and will need to include an on/off switch and a selector between the two intervals. You will need to design and test the circuit to confirm it it performs adequately. Then I will need several finished PCB's with all mounted components and circuit diagrams specified for manufacturing. This is a professional project, please do not bid if you cannot deliver professional service and quality. You will need further info before you make your final bid, please contact me to get that information and to demonstrate your expertise.

I can design the circuit for you. Prototype it and show you a video and photograph it. If you require more pcbs i can handover the design and gerber files to you. You can get it done at your location. It will be cheaper and faster that way.
