Re: Railway Modeller - Brockhampton & Umbridge

Personally, I don't mind the ads. They're fore and aft of the main stories and so it's easy to skip over them. Though I usually browse through them to see what new developments there are. I still have an 00 indoor railway so am always on the look-out for GER related releases. I'm pleased to say the ...

Re: Initial experiments with Bluetooth and Arduino

I believe you should be right chuffed with what you have achieved Rik given you were born in a generation where computers and coding were not mainstream. Thanks Tom .... not quite over the hill (yet) ..... ;) I've always tinkered with programming, ever since I got my first Commodore Vic 20 and then...

Re: Initial experiments with Bluetooth and Arduino

But if you what to move the loco or even the electronics with the SD Card, I will gladly take it off your hands........ :lol: :lol: :lol: :lol: Thanks Rod. Although it looks very toylike, it's actually quite useful as a test-bed loco. The three components of the body just clip together, so it's dea...

Re: Initial experiments with Bluetooth and Arduino

I think I've improved the sound files - though maybe you should be the judge. https://youtu.be/cMmQ83VglPY . I've blogged what I've done here just in case anyone ever wants to have a try themselves: https://riksrailway.blogspot.com/2019/07/bluetooth-phone-app-loco-control-part-4.html . I think I've ...

Railway Modeller - Brockhampton & Umbridge

Excellent article from Peter in the August edition of RM describing his railway - with a wonderful set of photos. Congratulations, Peter. I'm sure this will tempt many to venture out into the garden. Thanks also for the honorable mention. The RC Trains Tx22 shown in the photo is of special significa...

Re: Initial experiments with Bluetooth and Arduino

Latest developments. I've now incorporated sound from a small SD Player module. The tracks are played either in response to key presses on the app (ie the horn and the engine start / stop) and the speed setting determines which of three tracks play (idle, slow speed, fast speed). Not yet perfect. Th...

Re: Initial experiments with Bluetooth and Arduino

I've now discovered how to vary the PWM setting and so here's how the loco behaves on 12kHz and 8kHz. Most human hearing goes up to about 20kz, although sensitivity at the higher frequencies drops off as you get older. From memory 'silent drive' DCC decoders run above 15kHz. I can hear the buzz fro...

Re: Initial experiments with Bluetooth and Arduino

Further dabblings. I'm now using another app called RoboRemo, which enables me to design my own controller. I've also changed the coding so I get a much wider range of speed steps - but these seem to depend on the PWM setting I use. Steve Massikker uses 122.5Hz, which makes the loco growl especially...

At least I should finish before Crossrail.
And cheaper :(

Really enjoying watching this develop. As Tom says, a proper railway..... 8) 8)

Re: Initial experiments with Bluetooth and Arduino

Rik, not sure if you are interested ( it's not Arduino or Bluetooth!) but I've just found a long and detailed thread, with code, for using NRF240L01+ with Picaxe, on the Picaxe forum. https://picaxeforum.co.uk/threads/using-inhaos-rf2400-2-4-ghz-rf-modules.19036/ I might well be interested later on...

Re: The Great Garden Railway Inspection Reports

Sounds very much like my railway - some days there are absolutely no inhabitants at all, other days you can't move for people who mostly seem rooted to the spot!

Bootiful photos, Andrew. Those coaches look just right in the garden setting.

Re: Initial experiments with Bluetooth and Arduino

BTW - Just went strolling off down the street with my phone and put the loco on a length of track on the front lawn. I got a range of 46m (well 46 large strides). So should be adequate for most modest gardens.

Re: Initial experiments with Bluetooth and Arduino

With regards to the lack of tactility, it looks like it should be pretty straightforward (for anyone with the prerequisite knowledge) to make a transmitter like the common knob-and-reverse-switch type that works over the bluetooth link. I have been playing with alternatives to the usual Deltang typ...

Re: Initial experiments with Bluetooth and Arduino

Rik I love this idea and think it looks very funky. It's certainly cheap and for that is quite appealing. One of the down sides is only 10 steps for control. Do you know if this can be changed later on to a much greater number, like 100? Secondly, will this only work with a 12v ish supply? What abo...
