    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!

    Nice job changing the voltage from six to twelve on the small bike. If I need any advice to change mine I will let you know. Thanks

    Use a ac to dc 2/4 diode. And then step it up. 😉 To 12v

    I'm confused, why not just use a boost converter 6v -> 12v for modern accessories, and saves you a few days of work

    Another cool project, but in terms of Headlights why not simply switch to an led set? You'd get brighter output with less power being easier on the circuit and actually saving a small amount of gas during its life.

    You want to upgrade to a 55W headlight, but instead could have put in a lower power LED headlight that consumed less power, put out more light, and you wouldn't have had to redesign anything to allow for extra power consumption.

    Very interesting! I would like to convert my old, battery less, motorcycle from 6 to 12 volt. It only have a induction and a zener like what is mentioned in the video. How do I calculate the size of the induction spool?

    Can I ask you to hack these cheap Bluetooth 5.0 true wireless IEM’s? These look like promising until they have a arm processor,’flash storage and a OS running on it. Could it be modified to auto apply equalization ou run some custom code?
    It’s a rtl8763bfr Realtek SoC based units!
    Just for reference I’m using one of a brand name QCY model T1 (generic, very cheap and impressively good sound quality), but there also others like xiaomi air dots for example that uses the same SoC

    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.

  • Nitish Isad

    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!

    Awesome project. Good working prototype, probably needs measures to control vibration effects like weakened solder joints (heatsink mass) and waterproofing (silicone coating everything).

    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.

    Great info but I didn’t see your reasonintnall the way with most of the things you decided to do. Like why you chose sizes resistors and how much the system actually put out and why you chose the new coil. How man turns did the coil have . Stuff like thet
