I've tried posting this three times unsuccessfully(3 days).
While cleaning (and running trains more), I got distracted by whistling while I was working.
I have been accumulating trains without whistles. Enough I twice have recently assembled 4 trains at a time, and to not been able to blow a whistle on one "in celebration".
The fabricating flu struck me as I looked into a box. I had two gift alarm clocks with crossbucks and lights. I've had a half dozen over the years. They spend more of their lives in boxes, than on shelves as knick knacks, so I decided to make them into stationary layout accessories.
I removed the electronics from one, and inserted them, and the silicone the speaker into a Pringles can and added a tiny temp on button.
I had heard about folks doing the can trick for MP3/ipod use, and always wanted to hear the difference.
Well, it is a huge improvement.
It sounds great compared to it being in its factory enclosure. "Tin like" sound is gone and mid.s and bass jumped sky high.
Its loud enough to easily be heard over 6 engines (4 trains, 35-45 cars).
Just "toy sounds", whistle, then chug, then warning bells, etc.
"very fake" but clearer than the old talking stations that play records, so I'm good with it.
Wiring the second one I was thinking more, and jumped the activation switch input, putting the button on the power leads instead.
This way the sounds stop playing as the button is let go of, and I can blow the whistle in an almost proper way (only one length of horn blast, not short, not long, but a "medium"). Held down, it plays the whole effect track, looping non stop.
I kept the next one in the base seen next to Puppy, and below, because the Pringles can is too loud, and lasts too long playing the whole thing, for prudent late night running.
I removed the crossbuck post so its base would be small enough to fit on the shelf near the controls and used that area to mount a temp on type rocker switch on it.
(The can of chips is under the layout till I can fit it a tunnel, topside).
Fabrication flu's fever, was almost normal again, till I picked up the pole.
I suddenly saw something.
I took off the zebra stripe clock board, and the cross bucks, moved the light bar further up the pole and screwed it into place. I popped out the red lenses, and swapped in two 14v 100ma bulbs. The aim looking awkward, I heated each lights mount, and turn them away from each other 30-40°, and then angled them down some.
The pole was hollow plastic. I open up the hole drilling out the pole bottom, and it now fits snugly over a small terminal finger nut.
I still need to give it "real" wiring.
But I am very pleased with the mock up.
How did I test it?
