    Love striping down odd electronics.

    Hope your social distancing from the spiders in the shed. Stay safe

    I'm sorry, all I see when I look at that, is one of those old tape player cases that been repurposed.

    Hate to break the bad news to you but your chances of getting a refund for this product is very slim

    What about your 12V diesel heater

    It's really just an old-school power bank. Lead-acid instead of LiIon. 12V output instead of USB. Complete with light.

    Does Adam Welch, know your in your shed?, Will he give your a strike.

    Hi Julian, thanks for another interesting video. On a different subject I came across a bargain transceiver today, there 50p each for a complete module, from RF Solutions in the UK. Have a look in their outlet, seem perfect for your shed to house comms?

    Why not do what BigClive does and wear another coat?

    My first thought when you mentioned the dead lead-acid batteries was "you can replace those."

    In order to defrost a windshield to 50% of the area at -2 celcius while the car isn't moving you need at least 500 watts and a 50 watt fan driving it. This is why all the 100-300watt dash defrosters sold in autoparts stores don't do the job. The chinesium inventors are apparently oblivious to our last 60 years or so history of development on such things. A typical car defroster puts out the equivalent of over 5000 watts of hot air to defrost while moving.
    My question for you is why not (for your application) just connect a couple 100watt resistors to a $8 line thermostat off Amazon and have a tiny heater that is more or less oblivious to input voltage? Then you could control the heat output by varying your input voltage.

    hey 🙂 and good morning to you too
    one of your old videos helped me it was " Joule Thief " circuit and because you love what you doing you could help other people by making difficult things easier .. so my comment here is just a massage saying : thank you for what you doing 🙂

    Now we just need the strip down and fault finding video on the 12v diesel space heater thats died, we need to know whats wrong with it and why its died 😉

    100W is a complete wast of time… just scrape your window as it's far more efficient and carbon neutral.

    Just run a couple 100w incandescent light bulbs.. uh, torches? Also Julian, let's start a petition to ban LEDs from the planet because the blinking causes mental illness. OK? I guess they'd be ok with some kind of phosphor coating to dampen the madness. Be safe over there OM
