Looking for someone to design a timing circuit to control the time between releasing two solenoid valves. After the first is released then the time will begin before it releases the second solenoid. The times must be selectable from 1/1000 of a second to 3 seconds. The increments are halved, 1000, 500, 250, 125, 60, 30,etc.. Requirements; must be portable with own battery supply, very small and lightweight, including the small solenoids. Don't tell me you can't do it! I have confidence in you guys.
