Hello, I'am from Europe, Luxembourg and Z-Freak :angel: For some time i am working on sound projects for Z scale. I wanted to show you my last work that will be presented first to public this weekend on a yearly German Z exposition in Zell/Mosella, not far away from my hometown Luxembourg. I believe that this is the first in the world totaly integrated, so enjoy the (extremly compressed) video attached. The video is in reality a .wmv style, but I was just able to load it up as .avi. If you insist with your mediaplayer, he will make it, otherwise it should be necessary to change the extension back to .wmv. Greetings Armand
Armand, welcome to Trainboard. Very nice movie. Are you using dcc to control the diode. Robert Ray did one also. I hope you show us more of your work.
Hi Armand, Welcome to Trainboard! Excellent work on your sound decoder install! Did you install it in the tender or in the loco? And what brand of decoder did you use?
Very nice. If your decoder supports it, you should be able to tweak the amount of chuffs per revolution. There should be 4 chuffs per revolution of a driver... hard to tell in the video, but it looks like the wheels are spinning maybe one revolution per chuff... ie sound too slow or drivers too fast.
Just when I think it's safe to pull out my wallet!!!! Nicely done Armand, and welcome. We would all love to see more pics and vids when you get a chance.
Graves, its never safe to pull out your wallet in z. Armand, I was looking at the fire flicker, and I didn't have the sound on. Wow, what a difference. Kez, better send your cabforward to Armand.
Hello Armand and welcome to Trainboard. I had the chance to see all your stunning work on the Z-Friends Europe Forum. Please show our friends on this forum more of your incredible work.
Hello friends, Hello Jürg, how this world is small ;-) Mike, with the chuffs, it's all stuff of programming the decoder. And in Z, when you synchronize the sound with the wheel's it's a little bit sounding as sawing machine. So like it's adaptable the best is that everybody can regulate it to his own appreciation. I will put more informations later, I have just to change picture size and some text to be able to upload everything.
Hello, Just for the name, it's from a book of Erich Kastner where was a boy named "Gustav with the horn" Now to the stuff. It was important to me to not make visible holes in the body. Anyway, in Z they would be to small to let sound pass. And holes you need not only for sound but also because this kind of decoder become hotter than the standard. This way, 7 holes was made, one in the pcb at the front of the tender and 4 in the waterbox down in the frame and 2 other opposite the speaker. The decoder is a ESU loksound micro with a newly come out speaker of 13mm diameter. He fits in diagonal with no problem. It's DCC / Selectrix / Motorola / Analog and is 28,5x10x5 in size. The SL74 may be smaller, but there the loudspeaker problematic is not yet resolved. The decoder requires a lot of programmation work to adapte it, there is a very long list of CV's to look at. But it's therefore crazy flexible. The firebox illumination needed a lot of testing before it was running good. My first try with just a yellow one was looking more like a battery ill gyralight. I find out that just a 2 color led with pure yellow and pure red could make it. Because a fire also change colors during flickering and now... it's really burning. The directional led is installed as projector in the tender, a mirror foil on the motorblock create the effect. Copperfield made the same Also the sound is rather good for such small speaker.
Yes I really like the firebox flicker too. I did not buy an ESU decoder because the speaker is 100 ohms and too big, but now that they have a 13mm speaker I might try one.
Yes, thanks for all the pics! I did not have time to look at them all at work, but now that I am home looking at them, I can see all the great engineering you have done to finish this project! Excellent work Armand!
Hello Robert, Hello Jeff, The milling is made on simple Proxxon tools by hand, I have no special machinery. Just a coordinate table, so turning left, turning right... Only thing to take care is low engine speed. I use a micromot 40 with home-made PWM so I can make it turn very slow. With the plastic I use 200turns/min to avoid melting. The tools with integrated variator are allways to much quick for this. For the pickups, they come from one german member of the ZFE Forum. He make a lot of very fine work, I think he is one of the best in Europe. http://www.exact-messebau.de/minilok/start.htm
