Hi, I have with me a PCB design created for me, but I wish to have an consultation with an expert on the design to ensure it is robust enough before I take it to the Gerber design stage. The design is for an Emergency light PCB control which will switch to battery mode when the supply has been cut. Let me know should you be interested and I shall revert with more details. I am fine on hourly rate, but I also wish to chat online and discuss to go thru any doubts. Thank you. Lee Han Pin

Design a simple farm produce sorting machine. I have already built a rough prototype, but now need a properly engineered, and built machine, for showmanship purposes. The machine is all mechanical expect for some electrical motors.

Hi I have a small water valve that is being fed 14.5 dc volts as read on my meter to open a small solenoid to flow water. When Idle the circuit has 5 volts on it and is being monitored by the computer. I dont like the valve. I need to use a 120volt ac valve to flow the water. Can you provide a simple circuit that can detect the 14vdc flowing to the bad valve and turn on 120vdc from a wall socket plug onto a small 120ac volt valve.
