    Yes, let us know how you get on. I am going to have trouble explaining what I am doing – that’s the hard bit. But I will do it.

    “Perfect, perfect…perfect”

    Did anyone else have trouble listening to this bloke?
    I guess I am getting old!

      Initially I thought he was a bit of a prat but as the video progressed I appreciated that his instructions were very concise. By comparison many DIY type videos I’ve seen on YouTube are ruined by narrators / demonstrators who waffle on.

      Onion Girl was a bit of a character. Seemed like a good sort. Her last comment was spot on.

    Leds!. I remember when they first came onto the market in mid 70,s I had a bloke from Air Traffic Control at KSA ring up asking if Led displays were as reliable as the uniselectors that they used for temp, dewpoint readouts.
    Whats a uniselector now-a -days.

      Nah, don,t believe it. That process will make a primitive battery generating a few milliwatts @ fractions of a volt but not the 6-10 watts, 240 volt a.c or dc ( the ac is rectified to dc in the bulb ) that bulb is probably rated at. If it was capable of putting out that energy it would electrocute whoever was holding it.

        One suspects you are right and were my first MIL still alive I would try it out on her.
