24. Model railroad control panels pt 3, Finishing the build and adding switches and LEDs

[@MRR_Shadowolf]

One of the most educational electronic wiring videos I have seen on YT in years, very clearly and simply presented, outstanding!

[@H4MR0CK5]

Worth mentioning for anyone looking at the parts in the description: All Electronics went out of business in 2023, but from those ashes spawned a company called AREtronics which carries all of the hardware described in this video with the same part numbers.

This is exactly the information I need to move ahead with my tiny layout (4' x 8') with ten turnouts. I'm following the articles in your Electronics Projects book for my control panel. I am not using the Switch 8, just the toggle switches, but have been looking for a surer way to make sure the LEDs are wired correctly. This video, and I expect the next one, are just what I need for the details. I just ordered some jumpers with insulated alligators from All Electronics- I'd been shopping on the wrong hardware sites; thanks for that tip. ("Insulated alligators" - [snort snort])

That C&O Hudson in the intro............😍😍😍😍

[@tedbecker7872]

The parts list does not include the lighted LED pushbuttons used on the yard tracks on the big panel. What is source and part number for those buttons?

[@TheDCCGuy]

Ted-those are LP1OA1AG and I got them from Mouser. The last character “G” is for green but could be “R” for red etc. so you need to look over the listings.

Larry I am setting up my crossover lights. All four lights lite up have a battery holder similar to yours. two AA batteries works great for testing. My problem is I can not figure out the cross over wire setup the video is not clear enough to see all the leads from the LEDS can you get a close up of a cross over setup Thanks Tom

[@davennysouthern8717]

thanks Larry clear as crystal!!

[@philipwells9498]

Larry, You had mentioned a list of the various parts you have described in these great articles. I can't locate the list. How can I locate it on the site? Thank you.

[@TheDCCGuy]

Check the description for the video in question. That is where I and most KZbin creators put stuff like that.

[@MRR_Shadowolf]

Rewatching this series, had one question on this particular video. Is it the same if use toggle switches vice push buttons? ie still need mini jumper etc? Thx!

[@TheDCCGuy]

See video 209.

[@MRR_Shadowolf]

@@TheDCCGuy Will do, thank you!

[@johnmcdermott6220]

Question: Why is it not necessary to use resistors when connecting the LED Diodes

[@TheDCCGuy]

Because the Tortoises only draw about 20 milliamps and that is what it takes to light an LED.

[@darrylellis1495]

@@TheDCCGuy hi Larry im still puzzled if the LEDs are 3v dc then surely the 12v required to run the switch sould blow the LED cheers Darryl from south Australia

[@TheDCCGuy]

@@darrylellis1495 That’s just the magic of LEDs and electronics, and it works. For the in-depth details you’ll need to talk to an electrical engineer, which I am not.

Clip leads are like socks. They seem to disappear one by one.

Interesting: I have Clinchfield Challenger #670 in N-scale!

[@TheDCCGuy]

Beautiful machines!
