    In this HACKED! episode we will have a closer look at the electric generator of an old Simson moped. I will tell you a bit about how such an electric generator creates energy and afterwards modify the Simson one. This way we will convert the 6V electrical system of the moped into a 12V one. Let's get started!

    You can also simply use a relay in between battery and the charger's output and power it by charger's input voltage to connect battery to the charger only while its working and disconnect battery from the charger while its not working to avoid diode's small amounts of leakage.

    Is it also possible to connect the battery charger coil and the light coil in series an run the light straight from the battery?

    Excellent idea. Great and readily available voltage regulator. Would have liked it if you calculated the total impedence of the two coils and made use of a filter circuit.

    Why don't just rewire the light directly via DC supply, and voltage could be adjusted by buck boost converter. LEDs could be ideal then.

    Dear GreatScott, your channel is really awesome! I am playing around with capacitive encoders, like the ones you can find on rotary encoders or digital vernier digital calipers, but I'm getting stuck. Is there any way to DIY such sensors (they seem to be made of specific PCB layouts that produce the variable capacitive effect. Thanks for the awesome content!

    I've turned my 49cc TaoTao moped into a ridable 750 watt generator. The charging system charges around 15 volts, but everything works fine. Not to mention I have a nitrous kit installed, and soon a 12 volt "turbo" kit! I love this thing!

    Would it not be cheaper and quicker to fit a used larger 12v motorbike rectifier regulator? More compact too and less risky for any electrical mishaps. Just my 2 cents worth. Great work as usual Scott.

    This solution is not going to work for very long with the headlight on since the LM317 can't provide enough current to keep the battery charged with the lights on. I would eliminate it altogether and connect the output straight to the battery. The headlight is basically running off the generator after a few minutes when the battery starts to get discharged so the generator has to provide enough current to handle the entire load of everything on the moped that will be using power including the all the lights and charging the battery as well or the battery will go dead in no time! Yamaha motorcycle models XS650, XS750 and XS100 used to have this problem because the generator didn't provide enough current at idle to charge the battery with the headlight on and after everyone started riding with their lights on all the time the battery would go dead if you were sitting very long in slow traffic.

    Awesome video, so happy I saw it. Even if USclip dropped the ball.
    Did anyone else realize that USclip failed to send a notification for this video?
    A strange thing happened a couple days ago, I was searching through the suggested sites and posts after watching the latest offering from my subscriptions, and then I see the latest posts from GreatScott!'s channel. It showed that I had watched them (Red bar beneath them), but it had the "Subscribe here" notification. I thought that was weird. I immediately looked through the list of those I had subscriptions to and his channel wasn't on my list anymore. I also saw that
    Julian Ilett's channel was also there (another of my previously subscribed channels). It too appeared as if I wasn't already subscribed. I immediately hit the subscribed icon and rang the notification bell.
    Then tonight after watching my favorites I saw that there was this video and another for
    Julian Ilett in my suggestion list. I searched through my notifications and neither were there. I clicked on them and sure enough, USclip still had me listed as a subscribed member. WTF USclip?

    with only 11. something Volts you are killing your Battery. Lead Acid Batteries need a solid 14.4 V to be charged correctly. You should take that into account. It also helps to decrease your heatproblem.

    Why you don't think about rewinding the old coils from ignition base by new winding wire? I achieved a few Watts of power after this operation. I used the same wire guage, but I add a maximum amounts of windings.
