Hello everyone,
I am looking for some help in designing a system for allowing power to LEGO transformers. This needs to be a 120v system. As you can see in the image below, I need the system to only have one push button. The controller needs to sequentially activate each group, but only after the button press. Then, power runs to the various LEGO models for the length of time we set the timer to.
This project is for a really cool display fundraiser. For the last few years our club has done fundraising for the Wake A Wish foundation. This year, our display is going to be an amusement park. There are going to be at least a dozen custom LEGO built amusement park rides. Kids will hit the push button to make the rides move. Normally, our timers that we already have would work fine. However, LEGO motors are pretty expensive and having them run for 5+ hours per day for 30 days completely wrecks them. By using this system, the motors only run for 1/3 of the time, and have a chance to cool down and not overheat.
If possible, I would prefer to stay away from ICs.
So, if anyone here can help out, I'd be super appreciative.
