Hi folks,
I'm building a "nitrogen burst system" to develop film negatives. The film sheets stand vertically in a tank filled with the developer, and a solenoid valve releases nitrogen under no more than 30psi on some interval (say, every 15sec) to agitate the developer. Ultimately, I'd like to be able to control the solenoid valve with my laptop to have easy control over the burst pattern (continuos, every 30 sec, every 15 sec etc ...) and automate things. I'm thinking I need some sort of micro-controller driving relays connected to the solenoid valve. Does that sound right ? What should I look into to start with ? Any advice on either designs or parts would be greatly appreciated ... thanks in advance.
