16 V AC POINT MOTOR? Answered
Hi there, I would like to say hi to the instructables members for a start.
I have always enjoyed reading from this site and I see that there is a lot of help in the topics posted here.
I am a Computer Technician that now wants to play in the hardware game (Are you all enjoying Windows 10?).
So I'm starting small with an arduino and the raspberry pi, (not side by side yet,) a few motors, servo's, 7" color crystal display, and other things that I have salvaged from stuff or found cheap. I have a few of these CD drive eject motors with lil' knobs
I was reading this post about how to make an electric magnet as I am trying to manually make my own point motor for my model train set.
For those in and not in the know, here is some information about what I am trying to do.
Create 2 electric magnet coils that pull or repel a nail or metal bar where an upright pin ~2-4 mm is able to travel a distance of ~6-8mm (oo Gauge) in order to change a track piece from one position of a "junction point" to the other, allowing the train to change track or take another route.
I would like to try and do this myself as I have plenty of different types of gauge wire, dpdt's (for pole switch?), nails or metal bars(to act as middle pin maybe and bar to be pulled back and forth), diodes (for bridge rectifier) , resistors (to calm the voltage down if I have to as I think it will get rather warm else), a constant power supply (16V ac admittedly) and plenty of BABY BABY small yet rather strong.. magnets..etc.. ( BTW These were taken from a motor that was inside some water speakers, for perfect reasons the motor had a spin disc attached to it with 3 very small magnets, then in the water compartment there is a spin disc with more magnets attached and a wirly-gig to create the siphon to jettison the water up when the music is played so I now own 60 of the little blighters, (that's if i need them at all to be honest I'm a little lost in this idea))
So please take me as a n00b and please help me in going about this. Yes I could go buy one, but what does that achieve, when I believe I have everything I need at my fingertips and I wish to learn.
I presume I will need to deal with the constant AC in order to be able to make a switch to change the polarity of the two coils in order to pull or repel the magnet or nail in either direction to then move the tracks junction from one line to another.
I'm going to try and make some coils, in some rather thin wire that is insulated.
Thanks again for any replies.
