what is the correct jumper to use, what I have works but fits poorly
A standard .1" .025 square post jumper is what the posts are sized for.
Is the Power on the board DC? if so what voltage and total amps could be supplied. I am wondering about stealing a little for other things
The regulator is 12 volts. Note that the filter cap is really sized for the job, if you wanted any significant power (more than a few ma), you'd probably want to add a capacitor at J2. If you intend to draw more than about 20-30 MA, you'd also probably need a heatsink on the regulator.
I understand that cap can be added to increase delay. Is there a way that the relay could be made to come on when train comes into the section, but only stay on for a set duration? Say 500 milliseconds. What I want to do is parrot a button push.
Not with the present design, this was really intended as a signal driver for the insulated track.
...Opps one more question
I soldered with rosin core solder, should I clean the board? If so how should I do it
I use 91% or 99% Isopropyl Alcohol for my board cleaning. I use an old toothbrush to do the cleaning.
Indeed Master GRJ, I am a Padawan full of questions. I am certain that at times it gets old, I truly appreciate your willingness to answer them.
Jumper
Got it, struggled trying to find them, almost replied asking for more help. Fell into calling it a "shunt" bingo more than I can even choose from
Power
Hmm sounds like a bad idea then, especially if it starts messing up the whole cap thing. What I was thinking is using the PS on the board to run a couple of LED's, in a target signal for instance. That way add this board to the base and I would have it all. Perhaps it is better to just do it as two different boards.
Button Push
Unfortunate for this application, but I understand
Cleaning
That is what I was thinking of doing, this confirms it.
Speaking of cleaning. I am using rosin core SnPb, should I always be cleaning joints or just when it is a mess like the back of a board. When I join wires I have not been cleaning the joint.
Thank you very much for the help
