LEDs--Color, Voltage, Current, And More! (127)

[@garylandean7358]

Thank you for the information. Since I stopped receiving email notifications I have been trying everything to get them to work. I will relax and just continue to check for new videos. I have looked at every video of yours I can find in the past couple of months. Retired after 50+ years working and collecting HO parts for the past 25 years. I want you to know that I have enjoyed your videos and information which have been of great help to me. I have a 12x16 foot area about ready to start laying my first track. Thank you again for all the information you provide to us all.

[@TheDCCGuy]

Gary, thanks on that, I’ll see what turns up. As for Athearn locos, the last ones I got were Genesis F-units which were made a while ago and still had bulbs. I need to now shed a number of Stewart/Bowser F-units and Atlas RS-3s.

[@tomschmidt3165]

Hi Larry, Another good episode. Thanks. BTW, Athearn switched to LED’s several years ago.

[@robertruyle583]

Thanks for the LED Color/Voltage chart. Great Vid.

[@howardhengstler4729]

I get notifications on the as you say. Thanks for the heads up. Enjoy your broadcasts they are fantastic!

[@CM-ARM]

You were talking about the notifications, I just go to Utube and go to the notifications and try to keep up. That's why I got to see you tonight. You were a recommendation and now I sub to you. Lots of information thanks, Chris

[@jurgensteuer770]

Good to know about the email notification. I like your channel and even have some of your books on DCC.

[@v4victory665]

Another great topic and another great lesson taught... Thanks Larry ! I learn so much from your vids.... 💯👍👍

[@markwakeley3835]

Very good lession.

[@vincenthuying98]

Very clear and concise Larry, thanks very much.

[@onkyonky4740]

I always get notified when you release new content that is why i am here within minutes of you posting. emails are so yesterday. keep the videos coming, thank you

[@chazco]

Great information. Disclaimer: I have not tried this, but I have heard if you flash the Red/Green bi color led at the correct rate, you will see yellow thereby giving you red, green and yellow from a single led.

[@TheDCCGuy]

Actually with the 3 legged version you can power both the red and green simultaneously to get something close to yellow; more orange than yellow. Modelers have been making target style signal heads that way for years.

[@t-traku-tube5883]

The "correct rate" is anything faster than the eye can detect. You can put one with a corresponding resistor across your DCC rails to check you have track power working.

[@toddbrien4184]

Larry. Great video. Brings back memory from my high school years taking electronics. My question for you is what is the white item in the foreground of your opening scene (second loco pulling the pulp wood car)? Thanks.

[@TheDCCGuy]

Todd, I assume you mean the small white marker beside the track? That marks the midpoint of the under track magnet used with Kadee couplers for uncoupling.

[@toddbrien4184]

Model Railroading With The DCC Guy. Yes. Thanks for the explanation. At a quick glance it looks like a milk jug. Lol. Keep up the great videos. Have been learning a lot from your videos.

[@mariner3485]

Good video! One topic that I would be interested in seeing you cover is computers: for decoder programming, as well as for layout operation - I've seen some youtube videos on NCE accessory decoders where the layout can be controlled from the PC. So 'how much' computer do I need to buy to 'get started' with 'Decoder Pro', LokSound programming, DCC computerized signals for a layout., etc. Thanks! EDIT: FYI - I currently have a MAC and am thinking PC for my next computer. Apple just doesn't work for so many things today (like most of the layout planning software, etc...).

[@TheDCCGuy]

There is a whole series of videos on DecoderPro and various interfaces. Go to my channel page and they are all grouped in a common section/playlist.

[@irrationaltimer4901]

Now when you say 1k resistor, what power rating do I use? I'm seeing brands with 1/2 watt and 1/4 watt. Which should I use for model RR?

[@TheDCCGuy]

1/4W is plenty for a single LED.

[@markgoodrich941]

Nice job as always. I did not know that they make bi-color LEDs. Do they make a green/white combo? I looked around some and didn't see any. Thinking about using them for class lights. Thanks.

[@TheDCCGuy]

I would love to find green/white for use as class light but so far no go.

[@markgoodrich941]

@@TheDCCGuy Thanks

[@verybusy8728]

I have a Rapido Royal Hudson and it looks like they are using a white/green LED for class lights. Maybe, they are available somewhere! !

[@markgoodrich941]

@@verybusy8728 Thanks, I'll keep looking.

[@marksawyer5299]

Humm...I'm not sure why KZbin decided to do that given some of our working situations. I'm also not sure if they were tracking click through numbers..what ever. I'm not sure how many of your 7500 subscribers are professional model railroaders..I'm thinking very few. When I would get an email to notify me of the new videos from one of my subscriptions I would know that once I got home that there was new content to look forward to. Technical stuff from You..Mike Fifer etc. Great videos from Luke Towan and Collin Sullivan etc. I'm at 160 in my favorite/Sub list and if I didn't enjoy every one of them they wouldn't be on the left side of the page. So in essence they want me to watch the videos driving down the interstate at 80mph? Or do they want me to have to come home and search for new content on my subscription list? I chose to be alerted..I chose my channel subscriptions. Can one of you creators figure out the thought process here? Thanks Mark

[@JohnAnthonyMcKenna]

Hi I think you have an excellent channel, really informative. To confirm I have registered with your channel, but Only get notified on my mobile. Tony McKenna Liverpool England.

[@TheDCCGuy]

Thanks Tony.

[@politicsandtrains]

Good day, what would the typical resister you would require from Amazon to us with these typical LED's, i see lots of combination packs on Amazon with differant values, what I wanted to do is put lights on a track board that would indicate which track is powered using an Atlas switch control.

[@TheDCCGuy]

A 1000 okm (1K) will usually work for voltages in the 12 VDC range. However LEDs vary in their brightness and voltage so it is a good idea to have some bracketing 1K just i case you need one. I have videos on using LEDs for locos, buildings, etc., as well as one just on LEDs (#127) so do a search on my channel page or just scan down.

[@Tnapvrvideo]

Where can I buy these types of red, green, yellow, and white LED bulbs? Thank you!

[@TheDCCGuy]

AllElectronics.com, eBay

[@Tnapvrvideo]

Hi, this link took me to three links that do not appear to sell LED bulbs. ?

[@TheDCCGuy]

Try it now I took out the space between all and electronics.

[@Tnapvrvideo]

Perfect. Thank you! I located their 300 and 400 qty packets of 3mm and 5mm LED bulbs in multiple colors, but they offer no information on the LED "voltage across" or a stated Milliamp current. Thoughts?

[@TheDCCGuy]

Assume about 2 volts for red and yellow, 3 volts for white and green, and .020 amps

[@nateshon3eastbroadtoprailr448]

The funny thing is I get notified via e-mail when I go live on my channel and when I receive a comment or reply to a comment on any video including from other channels, go figure. I am extremely unhappy with KZbin's decision on this and I think it will negatively impact small channels and YT's ad revenue.

[@markgoodrich941]

I agree with you. I saw no notice that this was to take place. I went through my settings and checked and rechecked trying to figure out what was wrong. When along I didn't have anything wrong.

[@nolanknoepfle8044]

Have you seen or used an led tester? You can get one for less than $5.00 on eBay

[@nateshon3eastbroadtoprailr448]

I use 1K ohm resistors with all LED's for DCC and then fine tune the brilliance via the decoder CV's

[@TheDCCGuy]

That option is only available with a limited number of decoders, mainly Tsunamis.

[@nateshon3eastbroadtoprailr448]

@@TheDCCGuy I think NCE, TCS, and ESU have that option

[@TheDCCGuy]

I know that some can control the amount of dimming but have not been able to find brightness of the undimmed lights like with the Tsunami2 Guess I need to dig deeper.

[@earlcory]

You also get notifications in Windows 10 in the Notifications window.

[@TheDCCGuy]

Yes, it sounds more and more like they just discontinued the email notifications. I need to find time to see what videos have been done on this, and see what all is covered.

[@mikebeam822]

my 2 cents worth about email notifications, i.e., From my view one doesn't need to open the email notifications since the title tells me who has new videos. that's all I need to know.

[@TheDCCGuy]

Exactly, so now a lot of subscribers who depended on the emails will be less likely to watch. Maybe they were thinking it would force people to visit KZbin more often just to stay up to date. Personally I know my numbers have gone down in the past month!

[@dougdearinger5837]

I take it the clock behind you is dead?

[@TheDCCGuy]

Fast clock, only runs when turned on by the controller.

Great video brother can we become youtube friends...
