A transistor, which the output of the 4N35 is, needs a load or pull up resistor taken to VCC (the circuit posted by Trevora using the 6N137 already has one with R3). You can switch an internal pull up resistor into circuit on an Arduino input pin, I normally don't bother and use the external circuitry as with the 6N137 BTW pins 5 & 8 on a 6N137 are not "no connections", they go to the internal circuitry which is a lot more than what the basic schematic shows and must be used.

*That's where I got the figures from (amongst others) and your precis corroborates my statement. I went back over the years to see the trends. I looked at several different sites and the overall trends are the same, even though the end figures vary from one site to the other.

IOS penetration of the mainstream computer market hasn't changed dramatically over the years contrary to Apple fans opinions. It's even diminished significantly on mobile devices from a near monopoly to about 25% of the market. IMHO Without the US market where it dominates, iOS could well be dead by now, apart from the diehard users. Linux has long been the dominant cloud OS Windows is still the main PC OS (about 70%), Linux Distros (ignoring Chrome OS) are nowhere, with less than 2%.

Yes It should've been run through the anti-virus software first,...........Oh, wait a minute........☹️

Rubbish. There's nothing wrong with Windows if it is correctly installed and maintained. Windows is used because it does everything the (business) customer wants. This problem is no different to Kaspersky putting out an update for home PCs that that turns out to be a system killer. Although the result would be less catastrophic.

I visited it a few years back and I can't remember leaving the station. We got off the train on the Leeds side, went up the ramp then across the Footbridge to the far platform. IIRC there may have been a gate or something available to divide the Worth Valley bit from NR, if required. EDIT Gate's open on this image: This one is open as well:

Tyseley's VT base exists within a NR site but the two company's operations are clearly separated, no shared facilities in the site apart from the access tracks.

I thought Keighley had a shared footbridge and you could access the heritage line without exiting the station?

So you think your layout wiring is rubbish? Corner of a large US layout in the former Slinger, Wisconsin depot (station building)

Another new one, this time from Steel Highway started streaming today. Slinger WI, showing the junction between CN & Wisconsin & Southern.

Could you please explain. All I see is a frame from a video that doesn't play What description?

Brain in neutral again tonight. More rubbish removed.

Whereas two bedroom maids could do one evey 3 minutes.......... Amazing what AI can produce.
