This would seem to be the case as the Arduino IDE can't tell which version it is or it would detect it automatically and we wouldn't have to enter the version by hand.

The type of Arduino is printed on it

I save such things in non-volatile RAM in the Arduino. Sure you're well aware of that though

I've just searched thorugh all the sketches I have used since I got this desktop several years ago and they all use either ID codes found by running a separate sketch or by searching 1-wire devices within the main sketch. All I can think of is that was mentioned in a post on here - either started by me or in reply to someone else's. That's "a needle in a haystack!" However, I did come across a reference to an Arduino 1-wire library with the facility to skip the ID selection :- http://www.pjrc.com/teensy/td_libs_OneWire.html This doesn't "ring any bells" - I thought I got this from somewhere else but this seems to be one answer

I'm still searching for that code, so far without success Been trying to think which of my many Arduino based projects this would apply to. I ought to produce a page with all the Arduino sketch snippets. I really need to get myself better organised

Not ATM I'm afraid - the USB cable has been knawed through I'll have to repair it - yet another job to add to my never ending list

That's very useful if you have several 1-wire devices connected and I do the same but with only one device you can use different code that bypasses the device ID. I think it's in the Arduino web page or I could find it if you like.

The ball bearings came today so I'm hoping to install the new wheels on the north side shortly - maybe tomorrow

OK - Found the Fotos Firstly the wheel carriers. Design model and printed part for the south side. These take an axle (a smooth shanked SS bolt). Modified design to do away with axles for the north side which is much lighter than the south side. And now the wheels. Cross-section of wheel showing where the ball bearing fits in the middle 3D print design for the wheel halves. And the printed wheel parts, bolted together with the ball bearing in between.

Hmm... I thought I'd posted more in this thread as I have progressed this project a fair bit since the last post above. I have new 3D printed wheels and wheel carriers. Wheels are 100mm OD with ball bearings fitted between printed halves that are bolted together. The carriers take either axles or the bearings directly and ledge under the timbers that form the ROR carriage. As with the turned wheels above these have a V grooves and run on inverted aluminium angle. 3D printed carriers provided an easy way of getting the axles at right angles to the rails. I'll see if I can find the photos. I'm posting now as I've done a little bit more to this today. Progress has been delayed due to mislaying a couple of bearings wanted for the north side - the south side is finished. This morning I finally gave up on trying to find the missing bearings and ordered some more. Then this afternoon I removed the winch that I was using to pull Tim's wheelchair up the steep ramps outside the house, ready to install in the obsy to pull the roof on and off.

That should be alright

Adding ASCOM control to my focuser systems is definitely on my list but ATM I really feel I must finish some of my other projects first I already have too many on the go and the manual remote control is working pretty well.

Very sensible I'm only using 1-wire stepper control to reduce and simplify the kit at each camera. It's mainly the built-in ID code in the 1-wire devices that make the difference - I can stick them all on the same pair of wires. No need for special selection circuitry

I don't know about ascom-based programs but I used an Arduino Nano to control cooling for a cold finger cooled 1100D DSLR a while back with an LCD display running off digital I/O lines and using a DHT22 to read temperature and humidity near the image sensor to display dew point. Cold finger temperature was read with a DS18B20. The serial I/O was assigned to computer readout. BTW - you can use 1-wire to control the stepper motor. I am doing that for my multiple CCTV project for pan & tilt control though I haven't written the Arduino sketch that controls the whole system yet. It's yet another project in progress

Brilliant project Good luck

I said I'd get back to this in my CCTV thread so here goes... I have the wind direction encoder base printed.

Brilliant! You've done very well indeed

Thank you Ivo I will be happy to test your Beta version when I'm in a position to do so. A great addition to a superb app.

Pretty much made to fit the car Great project - very interesting

This is something I want to sort out soon. I have incremental focus control with push buttons which works well but I need to be out in the observatory warm room to control the focus - everything else (except opening and closing the roof) I can do from indoors. Remote wifi focussing would be good - automatic focussing would be even better

Wonderful news That's what got my cousin at an early age.

Wonderful So great to have all these resources available in one place - thank you very much

I'll be adding this in due course but I have a number of things to do first. eg. trying to find out why my laptop won't stay connected to the EQ8 for more than a few minutes

I shall be printing the parts for my weather station shortly with my new UP Plus 2 printer when the black ABS filament I've ordered arrives - Monday or Tuesday they say I shall also be printing the brackets for my roll off roof

That's fine Dave, I'm pleased if you found some of my code useful And I'm very happy for you to include it in your project Now I plan to take your ideas to make myself a real "auto" focuser I guess I should have been able to sort it all out for myself but I'm still suffering from reduced mental capacity due to "emotional overload".
