I originally tried using micro controller with lcd, but because of potential temporary power failures and frequency of use of the dials; i decided to make an analog circuit that would be more robust under rougher conditions. I like the idea of using a PIC, seems to be the most efficient route...
If you would like to build two of these for me, and ship them then I will pay you. I have the motors and I will be mounting the buttons and variable dials on a separate place, so I would need those to be attached to 1 foot wires. I will also let you incorporate your own relay board, to keep both...
If you think it would be easier to use a rasp pi, relay board and hex code then lets do it that way! Would I just have a monitor and mouse connected to my rasp pi and it will work like in the video? That would be perfect!
Here is the relay board I have: https://www.amazon.com/gp/product/B0057OC5WK/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1
Your last two layouts appear to be different, which one should I use? The variable resistors that I have seen have 3 pins and the layout shows 2?
I almost understand enough...
I have used those blue relays with raspberry pi projects so I understand that relay and I understand the power supply needs, thank you so much.
The ports im familiar with on the blue relay are vcc, ground and the trigger wire, which of these ports conects to the diode and the +/-? If i am using...
Thank you! a couple more questions..
I think I have found the right spdt relay, it has five pins. Which pins connect where? The motors +/- connect to the spdt relay, correct? and which relay pins connect to the diode?
Also, what size and type of power supply should I use to not damage the fet?
Ok, I think I have my parts list sorted with everything I need. But I am confused on two segments of the schematic on what parts to use. here is a picture of what I need to clear up before I move on and can build this thing.
If you can explain those to me then I think Ive got it!
Why does that schematic have a push button and a push switch? Also, is it the variable resistor that determines run duration?

Ok just one more thing alertlinks, if you give me a list of the part names on that schematic I think I could order them all and do the soldering...
Wow thank you! I think I actually understand that schematic for the most part now! So If I were to make six of these boards, how would I wire them to a single power supply, and also what size/type of power supply would I need?
Also what kind of attachment circuit could I make that would run 3...
ALERLINKS has been helpful thank you. I need help building this still so anyone on the forum please let me know if you want to help me build this or do it for me for donation. Here are the PMs with ALERLINKS.
I need a relay circuit with an output of 12v. I need the relay to be activated by a button and run for a duration of time that is set with a knob/trimmer. times only need to be adjustable from 1-20 seconds roughly. when the timed circuit ends, it does not start again until the button is pushed...
