I've used an old servo board (removes the PWM) to power a buzzer (works well) but it's just not a train type sound.
Any thoughts on a hooter small enough to fit in an O scale unit ?

The best sound board I have found is Adafruit's "Audio FX", it comes in 2 MB/16 MB and mini or standard sizes and with/without built in amplifier.  Their 2W mono amp works well with the Audio FX to power a good speaker.

" With 27 MHz which means a long antenna, on both transmitter and receiver.
IF the distance between the transmitter and receiver isn't much, like when you are following the train switching,
neither antenna needs to be very long, 4-5 inches will do.
But if you decide to absorb the goodness of a malt beverage, while watching the choo-choo do it's thing,
you may lose control when the loco gets some distance away from you.

With 2.4 GHz  both antenna can be short, and I mean an inch or less."

Quite right and it works well indoors at this stage.
Hope to start garden track some time.
Local fixer upper of RC stuff has standardised on 'FlySky' 2.4 GHz.
He is my source of cheap 27 MHz transmitters and receivers - which helps (pensioner).
BUT now that I've learnt how easy and convenient it is after setting-up the tracks to whip in the batteries and away we go.
I wouldn't mind going for the 'FlySky' stuff when we get outdoors.

NO not smoking pot (yet) :)

I seem to have a few potential candidates for the 'FlySky' R.C. install at the moment. L:

I'm not sure if I want to R.C. all of my locos though ?

The idea of using BOTH track-power and R.C. together is appealing.



But I am considering how I could install R.C. on all my loco projects, just in case ! :P





My trusty ol' topless Porter, sans cab, and now sans rear wheels & fuel bunker ... :shocked:

... is getting a new tender, inspired by my favorite Porter with a tender photo !





Somehow or other both my Porters new cab & tender are taking shape from this inspiration. :thumb:





The new tender is based on a heavily modded & re-wheeled 'Tri-ang' Transcontinental passenger truck.

The trucks end-beams have been removed, which I don't do on car builds, to allow for the San Juan Car Co. 'Evolution' couplers.



The woodwork has been made from some of my favorite 'obechi' stripwood.

I may use the tender at the length in the photo.

But have given myself the option to shorten it by 1 or perhaps 2 planks worth, if I decide on a bit more of a 'shortie' look ! :cool:



:!:



Si.



As for the Plymouth at the moment, I'll probably come back to that in a while.

The Porter is def. the R.C. priority at M.M.M. for now at least. :)

I was uncertain about the size tender I wanted. ???

So as a pointer the vintage prototype photo gave me a few basic scaled measurements to work with.

Basic length in relation to the loco & height were derived from a 'measured sketch' on graph paper. :)



The Porter in the vintage photo, is of course a larger 3' gauge engine. :shocked:

But the proportions in overall length still look OK for my 2' gauge 1:35n2 version.

Perhaps a board or two shorter in the tender, as considered. :P








My mahogany front-beam is yet to be trimmed to the correct width by the way. :old dude:

It was an experiment in creating a square 'mortice' in the timber ...

... for directly fitting a San Juan Car Co. 'Evolution' coupler. :cool:



The even keener eyed out there, might notice as well, that the coupler is also upside-down ! :P

The M2.5 coupler pivot fixing would normally be underneath the locos end-beams.



:mex:

I don't think I'll use Joseph Stalin as the fireman in the final model either ! ;)
