Hey everybody, my name is jimmy still drinking that store brand coffee. Today, i bought a lot of that, but lets talk about some of the coffees that you guys are drinking. Thomas myers is drinking a solid chai tea. Actually, while watching some trains cant get much better than that, i completely agree and i do love chai tea. It tastes really good reminds me of christmas. Andy crawford says that hes drinking some plain old timmys this morning, and i love me some tim hortons, so good choice, andy and saint dane says that hes drinking some iron city, coffee from birmingham alabama. I do love birmingham and all those hills around it, full of iron. All right so, like i said, im going to be talking about arduinos, as well as a ton of other questions. Im going to be answering and right now, im going to start off with rachel r, she asked if she wonders if i have ever considered using an uno to sense, train motion to trigger sound. Yes, i have considered that and its something that ive kind of had like in, like not the back burner, but the middle burner of just like getting working and everything a couple things have held me back.
I want to make sure that i can 100 say all the file formats youll need correctly and that the minimal amount of cost is involved. So basically, you just need to buy the hardware, and the software would not be something that i would want you to pay for to be able to do that, because you do have to use certain audio file formats when it comes to using them with an arduino. So she says: shes looking to diy and use the arduino to simulate the sound of a diesel engine accelerating and decelerating. Now, if youre dc, i totally understand why you want to do that if you are dcc its probably going to be easier to look into sound decoders unless you are modeling z scale, because even inscale has really solid, sound decoders that are going to work really well, I have several engines with sound decoders back here and they work great all right. Greg mendowski is asking about if im going to do a series for 3d printing and how to design buildings now ive actually done a build. A video rather for train masters tv, where i did some of the basics of building design, and i will link that down here – that is a paid membership um i do a show on there called jimmys train works and ive done a video over there. Now he says he has two fdm and one resin printer now, depending on the size of the printers and everything and the scale that you are modeling, its really going to look, and i always recommend try to print as much as you can on resin, because you Can get a lot better detail, a lot easier out of that versus an fdm printer, and especially since resin printers have been getting a lot larger, so h0 scale, and even some o scale has opened up with that and ive did.
I just literally just did a whole video on that that ill link at the end of this. So thanks greg msc 1953. It says what does the michaels backdrop that i use right here. What is that called? Well, hang on one second, because i have another roll of it right here. This is from a brand called fadeless, and this one in particular, is if i can find a name for it um. It is just called clouds and uh. The number is p00564 or 564. and let me start that again: p0056468. and its just called clouds and its made by a brand called fadeless. And this is a four foot by 12 foot or if youre in the metric world 1.2 meters by 3.7 meters. So 48 square feet or 4.5 square meters, so there you go thats where that came from by the way says: theyre drinking, sweet, iced tea – and i do love me some ice tea because i am from the south love me: some sweet tea. All right. Ken long asked the question: what is a build up kit as to a kit? Well, a build up building is something you may see as a category on your favorite model. Railroad website as where to buy things, a build up is just simply a building that has already been put together. It is not a kit. You dont have to assemble it, its literally pop it on your layout, maybe scenic it in a little bit, but its ready to go.
So if youre not confident on your building skills, they are a great way to get really nice. Looking buildings on your layout, there are nowhere near as many built up buildings as there are kit buildings simply because theyre harder to manufacture, so manufacturers are going to do less theyre, also going to be more expensive typically than a kit, but they are a great way, Especially if youre not confident in your building skills, but if youre not confident, let me tell you something: i used to not be very confident my building skills either, and i just slowly worked at it. I bought inexpensive kits to build um. Dpm kits really helped me get my confidence, so just keep working at it youll you will get it trust me all right. I saw it online trains with shane uh asked if about wiring uh for dc versus dcc, so converting dc to dcc wiring, he had rescued a layout from a dumpster and it has block separations at one time. Although the wiring looks like its been butchered, what would be the best practice for rewiring it in dc? So if i hear this correctly, the wires pretty messed up, but it was still blocked off. So that probably means it has either some insulators or cut rail at different spots. Now the the biggest misconception about wiring for dc versus dcc. So if you have like the same level of complexity, lets lets say you have a large layout that has power blocks and all that kind of stuff that you have in dc youre, actually pretty much set up and ready to go for dcc.
You can literally unplug your dc system and plug in your dcc system and be pretty much fine. The only thing you have to make sure is that your wires are all on the theyre all on the same side. So lets say you have a loop of track. Whatever wire is connected to the inside, rail always has to be on that inside rail and whatever wire is connected to the outside. Rail always has to be on the outside rail, otherwise youre going to short circuit and most systems are just going to cut off and not let your train run even dcc, plus plus and dcc, plus plus ex have short circuit detection and thats. Just one thing that uh you have to make sure of, but dcc wiring is pretty simple: it takes out the need for power blocks for control its still a good idea to do some power districts with some circuit breakers, so that lets say you do have that Short circuit and it cuts off its not going to cut the entire layout off, especially if you have a larger layout but pretty much. What i would do in that situation is, i would probably trim the feeders. I would leave the feeders coming from the track and i would probably just run some new bus lines and connect those feeders and just make sure make sure youre connecting the same wires to the feeder so use color, coded wires, red and white, blue and white.
Just use two different colors, so you know which ones connecting where and then just be very careful and meticulous about which wire is connecting to the bus line so that you dont have a short circuit. Oh right, jerry, clough um. He says probably a bad time for this question, but why did i use a brass track on my outdoor layout? That was under the impression that nickel silver was less susceptible to corrosion, thanks for all the videos? Yes, the nickel silver stainless steel, all those those are better but theyre, also less available and theyre less expensive than brass and the layout the starter set that i bought to build. That came with a circle of brass track and, if youre doing a small layout, it is of my opinion that the track isnt going to matter as much if youre doing a large like yard spanning layout. You definitely want to do lower maintenance tracks. So the nickel silver, even stainless steel, if you can find it, those things are going to be better. But if youre doing a small layout like i just had to just run a quick sanding block over it the other day, and it took me all of a minute to get everything clean for running and it was good to go and if youre using something like. I can tell you: i have a difference because i have some older bachmann locomotives and then i also have some lgb locomotives.
The lgb locomotives pick up really well and they are. They do better even on corroded track as opposed to bachmann track, and if you do have a lot of, if you do have availability of a lot of brass track, there are track cleaning cars as well and track cleaning locomotives too. So you have a lot of options for that. But, yes, you are correct on that. Sparky 107 107 asked a bit of a different question. He asked um. Where do i get my hair cut because whoever does the top? Does it very nicely? I want to say thank you for that compliment. Sparky um, i cut my own hair. Thank you very much and it is its not bad. Whenever i get around to cutting it, you may know sometimes its longer than others i like to try and keep it as close to shaved as possible. Uh, sak or sac not sure asks. Is it easy to connect kado ho scale unit track with atlas code 83? Ho scale track now i double checked this to make sure with the kado website. Uh ho scale unit track is code 83. So in theory all you would need is track. Joiners, and you would probably you know. Joiners are pretty easy to remove. Kata includes a tool to do it a lot of their packs. So what i would do is probably remove the unit joiners, because thats going to give you a nice even spot and then just use some regular uh track clips that can just like connect it right.
There and then probably get some cork row bed just to go up there and just get it as close as you can. You may need to do some a little bit of elevation and maybe put some shims underneath it or something like that to get it exactly. The same height as the host scale unit track, but it really actually shouldnt be that difficult kado makes it pretty easy. If you need to put some other track on it, so all right, tia edge asked, do you have a list of all of your engines? Uh! No, i do not, but i actually dont have as many as i think people do. The majority of mine are norfolk southern um. I dont think i have. I have a southern one too, so i have a southern um alco 2137 thats, a bachmann lets see here the most of a single manufacturer i have is probably tied between kado and atlas. I have a kado sd70m 2588. I avocado sd70ace thats one one, one one. I have is that all my condos, i think that might be all my cottos believe it or not. Um. I have an atlas. Sd60. Thats 6603.. I have an atlas sd60m, those uh thats, a six eight one, four, those are my two. Those are two non sound. I have an uh sound one, a dash eight. I think its a dash eight, i cant remember, but its a eight three four five thats got a nice sound decoder in it, and then i also have a scale trains dash 8, 40 c.
If i didnt get that right, im going to put that right here and thats the the 888 and thats my nicest locomotive, thats a really good one, i also have a couple from fox valley, which is now part of scale trains um. I have a fox valley models: jeep 60. 7138. I then have um a fox valley, dash nine one of the heritage units or is it an es44, its one of the hair, its the lehigh valley heritage unit? And then i have a couple of broadway limiteds, but they dont run that well um, which is a shame because theyre really really nice locomotives, but theyre always really really jumpy, and i can never figure out why so. Those are all of my locomotives and those are probably the ones youve all seen. I really dont actually have that many locomotives im just starting to get into more of the collecting phase after completing this layout. So thank you for that question. Matt coogan. He actually has a couple of questions here. What adhesive do you use to glue down your cotter unit track im worried that i may need to move in the next couple of years, but would love to be able to reuse my track? Thank you for your time. So my adhesive of choice is latex caulk. Now it takes a while to dry, but in my experience its actually not that difficult to remove, even though i glue right where the unit joiners connect thats, usually i just put little dots on it and thats.
How i glue, rather than trying to glue the entire track it actually comes apart, pretty good. It holds pretty well, but its going to come apart. So that is my adhesive of choice for building a thing like that: thats whats, holding together the extra foam over here, thats whats doing all of that over there. So, thank you for that question and he also asked do i sell the be kind and play with train shirts? Yes, i do theyre on my teespring store ill put a link in the description below. You may also see it right here, just below the video, so kennedy, gauger or goucher im not quite sure how to pronounce your name. Sorry, if i butchered that i said this is probably something that ive done a prior video, but do you do block detection using an arduino and i actually have done several videos: ive done block detection using infrared sensors, ive done multi block systems and ive also done Current sensing and im going to link all of that playlist at the end of this video, so go look there. Thank you kennedy for that question. Jeff iverson says that he is learning so much, but he wants to know how he can use an arduino. In my model, railroad, so i dont think ive ever actually explained what exactly an arduino is. So an arduino is a class of electronic, its called a microcontroller. You may think its like a computer, but it cant really do everything that lets say a raspberry pi, a single board computer can do so, basically its a little micro controller, and you can get it to do quite a lot of things case in point.
Look what dc you see, plus plus and dcc, plus ex, are doing with them, so theres a lot of cool things you can do with it, but basically you can also use it for a lot of light and motor control. You can even use it as a stationary decoder havent gotten to that yet. But that is something that you can do so theres a lot of different uses. I have a whole playlist on that im, going to link that at the end of this video. So, thank you jeff for that question and then roland lawrence. He asked when do i plan on doing more arduino projects. I really appreciated your previous work with the arduino thanks all right. Well, i am actually doing a slight shift in what i do with arduinos. If youve watched this channel for any length of time, you know that ive done a lot of arduino projects as prototypes, and i havent really implemented a lot of them. Well, im going to be taking a lot of my projects and im going to be implementing them into something actually on a model railroad so that you can see how this is actually done. So this is what youre going to see coming up in the future. A lot of different things, youre going to see a lot of putting things into the actual use case of all the little prototypes that i have built. If you have a question that you want answered in next months, q – a put it in the comments below you – can also tell me what kind of coffee youre drinking i might mention it on the next episode of coffee and trains.
