HACKED!: 6V Electric Generator UPGRADE to 12V! 

6:11 _Did you mean_ *FULL BRIDGE RECTIFIER* *_Electroboom intensifies_*

dude you just need a Polrad Abzieher and your good

"Simson in Sicht - Upvotepflicht!" Always interesting videos for me starring a Simson as I own one myself and am currently rebuilding it

Next: Motorcycle - DIY or Buy?

Why the LM317? Its terribly inefficient and it can only charge at 1.5A with a strong heatsink. A decent 5A buck boost converter would do the same at a higher efficiency and a better peak voltage...

Got some problems with this one: - creating a second ground system to the one used by the coils is never a good idea in an automotive system since most loads rely on getting their ground from the frame which is also connected to the coils -> short circuit - the LM317 is only good for 37V, you showed that the open-circuit voltage is above 60v for those coils, so no good thats why most professional moped-regulators, like the vape system you showed, use more robust thrysistors which actually short excessive energy to ground for the headlights and also charge the battery with a thrysistor

Living life on the edge (literally) with that oscilloscope on the seat at 3:40 haha

Thank you very much! i have inherited an old CZ motorcycle, that is in dire need of similar modifications, since its generator is incapable of maintaining the headlight running (as required by regulations) and will eventually drain the battery. This video definitely helps with the inspiration for the work!

Please keep on working bro.. you are doing a great job by teaching and inspiring people to do diy projects that seems immpossible but are very easy and educative.. Keep it up bro.. Salute to you from an engineer & Love from India..

Don't use screw terminals! ..or any mechanical type wire termination on a vehicle or project subjected to regular vibration. That's a recipe for disaster. True, you will occasionally see a wire with a crimp termination and screw used for a chassis ground connection on vehicles. However this will always have a one-time-use friction or lock washer under the head of the screw. These days you will also see the entire assembly covered in an adhesive compound. The crimp termination used will always be a full loop type where the screw passes through the terminal before it is attached. If you don't want to use proper waterproof terminals that can be bought quite cheaply from China these days, get a bunch of insulated butt splice terminals for this. They are just as fast. Get a set of side cutters with a crimp terminal on the front of the jaws. Don't get the self ratcheting ones, just the simple kind that will be easy to use in tight spaces. I don't know if Deutschland has cheap 'pull your own parts off' type automotive junkyards like we do here in the USA. If you do, just go in with a set of wire cutters and look for the cars that have been at the junkyard the longest. These will often be stripped of most large components. I've only seen someone strip out a wiring harness a few times. They are still on the car 99% of the time when the vehicle is sent to the crusher. The newer the car is the better. Almost all vehicles have the wires routed under the carpet on the drivers side. Don't treat this like a delicate job. Bring the big stuff with you. Think power tools, carpet knife, crowbar, and bolt cutters. Don't carefully take things apart. I mean, don't trash good stuff others will want, but if a seat/headliner/door panel/carpet is already damaged don't worry about how to properly remove it, just brute-force your way in. If you have several vehicles to work with, go for the headlight, taillight, and trunk based wires only. These have 1-6 wires per connector and will have the longest wires attached. You can easily cut long enough wires on each side of the connectors for reuse on almost any project. Dome lights are another source of smaller gauge wires/connectors but still super long wires. I only go into the mess under a dashboard for the larger connectors if I need them. This kind of stuff is usually ignored on the junkyard's list of prices for parts. So, find the ugliest female teller at the checkout booth, and be super charming. You'll usually walk out paying almost nothing as pricing for such items is entirely up to the cashier's discretion...It works for me and while I'm only a few years older than Jeremy, I think I'd be the "ugly" wingman at the Saturday night club scene. Junkyards are often overlooked sources for lots of things beyond the simple car parts most people think of. If you can go inside and pick your own stuff they are a great source for cheap raw materials from fabrics, to sheet metal, knobs, switches, relays, high current diodes, solenoids, linear actuators, springs, latches, audio gear, and even IC's and connectors. People just don't think of these places as a source of raw materials. You can even find things like high frequency terminals and wiring. The airbag triggering system of a modern car is a very demanding system that requires a robust high speed connection. Anyways, those are just some basic ideas for alternatives. Things like crappy screw terminals on a vehicle are often the reason for the vehicles you see burning on the side of the road. Don't be that person! -Jake

4:30 Gotta love those German nouns.

I remember my time as a teenager working on my Puch x30 and my Puch maxi s, loved how simple they are build and how simple they where tuned 😂 you brought back some memories taking off that magnet wheel.

Really enjoyed this episode, you combined two of my favourite topics, bikes and electronics!

Just discovered this channel when I was searching for a way to convert my 1980 honda express 2 na50 from 6v to 12v. I dont know the first thing about electrical engineering. but im hoping that by following this guide, i wont fry my system. Wish me luck!

Fantastic video as always! i wish i knew electronics like you do! you clearly know your stuff.

I love your explanations and your accent...plus i can completely understand you! You are very thorough.

I love those old 2-stroke DDR bikes like Simson S51 and MZ ETZ 150. Greating from Czech rep.

Bro you are great constructor.. So.. why you don't use a DC-DC converter LM2598 istead of heater LM317.. It was nice conversion with ton of wasted energy..

This is EXACTLY what I needed! I am doing a 6v to 12v conversion on my 1978 Honda Odyssey.

Wie geil da machts du einfach ein video über deine simme :D geiles teil! Müsstest das viedeo eigentlich nochmal auf deutsch für die moped comunity hochladen

Nice mopeds! I have a little 2 stroke 73 Kawasaki 100cc motorcycle that's about the size of those bikes... Super fun to screw around on.

I love this video and your channel is great. I work as an electrical manufacturer. I build and wire electrical enclosures/panels for various automation needs, such as; canning plants (Coors beer), solar fields that track the sun, green houses that automate everything from sunshades to irrigation, and so much more. A few guys and i at the shop have some classuc mopeds that we have been upgrading. I have an old tomos moped that i converted to a 12v system with new LED headlights and turn/brake signals. I designed the wiring schematic myself and feel very accomplished in my efforts. With your videos i now feel like i have a greater understanding in electrical sytems and the confidence to build my own parts rather than buying expensive premade parts. Thank you for the knowledge gained

Your videos are always creative as you say at the end of the video. There's always a learning from your videos. 😉

Thank You! I also have a Simson S51 with a 6V system and wanted to convert it to 12V! Big Thanks!

Awesome video as always ! Great content !! THANKS GR8 Scott

Really good job, i'd like to learn more about stuff like this. specifically the in depth whys and hows electricity does things the ways it does them.

Hätte niemals gedacht, dass du mal videos mit Simson machst, finde ich sehr gut👍👌

I also have old Jawa 175 which use 6v, thanks for great video 💪

Hi Scott! Please make a video from building custom programmable ignition module on avr for chinese pitbike engine. A lot of people needs a programmable CDI but it's expensive to buy. DIY Programmable CDI should be good equivalent.

I just got to the opening tune, and I love this already.

Ohh old memories come back. I used a own a S50. It was a gift sent via Genex (you might be too young to know) from my dad from Canada. I remember the battery was always leaky. It was only there for the blink lights if I remember right. I used to build a 220V inverter right into the box for my beboshear shaver for camping in Czechoslovakia. Good memories. On this trip I must have changed the spokes of the rear wheel 2x over. Thank goodness I had enough. This moped really lasted me a good 12 years then I left the country.

You are best teacher in the world. I always wait for your awesome video. Thanks man

Excellent conversation Scott!

Thank you for the video... I always wondered about that rotating magnet of my motorcycle

Funny coincidence you uploaded this video..... I have a barn find of a Honda CB50J and was thinking about restoring it. The first thing I would have done is to change it to 12v since I recently almost bumped a Simson driver of his bike when it was dark. Greetings from Germany as well

Nice video. Suggestion : You could 3D print "Great Scott" and record it that amazing way you showed recently !

Interessantes Video, bin auch Simson Fahrer und habe meine Simson auch schon genau so umgebaut!

Good upgrade, but the 1.5A output will only give you about 18 watts of total power, however the battery charging, tail light, headlight and brake light will need more than 60 watts. I would have employed a full wave rectifier for each winding, then couple the output's of the two bridges, that will eliminate phase crossing the separate windings. Then filter and apply that rectified output into a buck boost regulator module rated to about 80 watts or more. The buck boost will give charge voltage regardless of the input voltage being lower than it's output, and there will be much less energy loss than using a passive regulator. I did a similar mod to a 212 kart motor and get over 50 watts from two similar coils. Thanks for posting.

I love your videos. I never miss one. But every time I watch you solder on perfboard or whatever and see how much solder you go through, I start worrying about future world solder supplies.

Nice piece of gear! Thanks for sharing.

My 1970 Honda SS50 has 6v system but the rectifier is half wave. I disconnected the ground side of the altrrnator coil and put both coil connections to a modern full wave bridge rectifier from ebay. Then connect the negative dc output to bike frame. Change all bulbs (now led), battery, horn to 12v and it works great! Changed wiring to run headlight from battery, now its never dim whatever the engine speed. Everything is bright and constant. Much safer.

Thanks 😊 for making us happy with these videos. Can you please make a video on logic analyzer or spectrum analyzer

Pretty beautiful job, dude!!! 😃

great scott is the greatest.kepp up making good videos:)

I'm glad I watched this video, I was wondering if you connect the grounds before and after ac to DC conversion using a full bridge rectifier... Now I know!

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

Love the video i own a 1978 Zundapp KS 50 sport version myself

Glad to see another video. Good one!

Your English accent has come a long way since you started. Good job.

Nice, this guide can be used on other old mopeds/motorcycles too, if there is circuit diagram available. i'm just bit worried about those screw terminals, i would use crimp connectors and make nice harness..

Good work man

Nice project Thanks for sharing :-)

I am currently learning about switching power electronics. This is just a perfect oportunity to expertiment and practice that knowledge! I just hope I don't fry my friends' motorcycles hehe.

For charge regulator, check PB137 instead of LM317. One is spesific to battery charging, while the other is generic.

I love simsons! they are so fun to ride ! Simson s51 was first moped i've ever ridden.

Many years ago ( about 40)I had Honda XL 250 . The electrical system was similar in that tail light /headlamp was ac powered and indicators hooter and brake light dc from battery. All 6 V. When headlamp was off a load resistor was substituted but problem was the battery was used as a voltage limiter and in a hot country it was over charged and died . Headlamp would then burn out. My crude solution was a voltage dependent load to control the maximum ac voltage from coil. bridge rectifier 2 x 2n3055 with fat 12 V 5 W zener and a 2W resistor 100 R all mounted on some heat sink fitted below headlamp for a bit of cooling. A bit crude but it worked .

Ich hab die Thumbnail gesehen und dachte mir, dass mir das doch bekannt vor kommt 😄 hab auch eine 6V Elektronik Zündung in meiner S51 Enduro :) Macht Spaß an den Moppeds zu schrauben, es ist noch so leicht, gerade für Anfänger.

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.

Nice and enjoyable !

, hey greatscot i really like this new project of yours, i hope you make more videos of motorbikes electronic circuits... tnx

Love the vids...keep them coming...u should do ur outro in a cinematic voice

nice job! luckely my Tomos moped is just running on 12V! :-) and my Saxonette is also 12V, but the 18650 conversion (from NiCD) kinda works, but still needs improvements :- )

Absolutely brilliant😊😊

Nice vid as always ;)

I just love your contents

yeah here we go again a good project 👍 keep up the good work and dont kill this channel with cheap tools ... dont mean cheap solutions 🙂

Wow. The timing on this video. I was outside working on a scooter i bought for cheap and was trying to revive.

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

Hi 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.

Nice update

This was fun ,, THanks :)

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!

Very good 👍

Simson is life simson is love ! i love the smell of gasoline and oil from old DDR machine in the morning ahhhh such a memories ...

and yes it may have been seen I have also done this once but without the defense aume but did cool ...well done

What about the tail Light now?

Could you make a tutorial for anodizing aluminium, i'd like to anodize the break and clutch lever orange on my moped

Thank to god.. same problem in my DT125 6volts.. now I have idea to convert in 12volts

we've been doing similar 6v to 12v conversions on VW beetles for a long time brother.

great video. Laughed at 4:44 ;)

2:48 The changing is in the angle between B and A not the area vector of the coil

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!

You could just use a step-up-converter. right? (For powering external divices)

Cool project. Can you make a video about getting a stable 5V power from a bike dynamo? Idealy to charge a phone. I tried some stuff myself but could not figure it out.

Nice video that's awesome....

I use 10W LED on my moped, since it's so much power efficient and also much brighter.

God bless Karl Clauss Dietel when designed the S50/S51, i think IFA combinat was the greatest thing in the eastern bloc. They achieved the impossible with economic and long lasting designs. German quality meets russian simplicity with every product they invented. The Trabant documentary is a great video to watch about the communism in DDR. The WAPE is a last generation ignition and generator for the Simson S51. There is a factory 12V system with a central electronics called ELBA. Much cheaper and much reliable compared to the old 6V tiristor or 6V with mechanical breaker.

You can use the exact same 3 resistor feedback circuit with a buck converter. Same battery charging behavior with far less losses.

i put neodym magnets in my Vespa Ciao's "generator" instead of the normal weak "magnet", power went from 18-20W to 100-150W ;), but had to change capacitor to a much higher voltage rating and cant remember capacity, but if capacity is to low or to high the motor will either have trouble maintaining idle or will have limited RPM. This was about 15 years ago, have not ridden ICE since i converted a Ciao to Electric (Google Electro Ciao)

You are Great Great!scott

Zimzon = Simson by the way, for the viewers outside Germany.....haha

Is not easier only to add a DC booster only to the lights and keeping the original design to the generator?

GreatScott!, Grate video. Would like to see how to bulid a RF amp.

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?

oscilloscope on a motorcycle. nerdy badass. love it.

LOL @ that conversion kit price! I bought an entire 250cc for not much more than that... I had to strip and clean the carbs, but after that it ran fine.

Why you added a diode instead of raising the resistor values with the correct ratio? Is that possible to use higher value resistors? Then why you use smaller value resistors plus a diolde?

Ich Feier deine Videos und sind auch echt hilfreich

I love your videos. But i think so much science for me. I still watch them tho just to see if i learn something about you
