NSL-32SR2. - ADVANCED PHOTONIX - Optocoupler, Photocell / LDR Output, Axial, 4 Pins, 25 mA, 2 kV | Farnell element14

FDV301N - ON SEMICONDUCTOR - MOSFET Transistor, N Channel, 220 mA, 25 V, 3.1 ohm, 4.5 V, 850 mV | Farnell element14

These are in romanian, since I ordered from Romania, so you'll have to search for them in the german site. Or change the language?

Rest of the components I ordered from mouser. They offer free shipping I think over $60 or so. If you need a mouser order list, I have that for the V1 board - IO, PSU, CTRL (bought the boards a long time ago, never had time to get to assemble them).

Cheers,
Sorin

Or you can use the replacement for the 5LN01, VN2222LL-G and just bent the leads a bit. See pic:

RS in the UK have increased the cost by ~44% for the same 100off rate. And much higher if only 50off (+157%) are bought.

You mean like, to design same thing from scratch on a totally different platform? I don't think so

ESP8266 should be compatible with Arduino, with the added benefit of having wifi available as well. So potentially you could remotely operate it with your cell phone. I heard the wifi part is not that reliable though, but I have not tested myself.

Also, not sure how much memory it has available.

It's not totally different, I could easily adapt your code. NodeMCU or weMOS are interesting for this use. I'd do myself, but I lack skills with PCB design.

I use it for a pair of IoT projects. Not bad at all.
