    Hello Instructables CommunityMe and my dad have made a succesful generator. it may be crude but it does produce over 12 volts.

    Hello Instructables CommunityMe and my dad have made a succesful generator. it may be crude but it does produce over 12 volts.

    I was planning to do that, but the process may be different for someone else due to different engine and parts, and I have neglected to take photos of building it.

    How fast is the engine? I looked online and didn't get good results. Some say around 5000 rpm and others 8000 rpm. I don't believe it's that fast. You guys know? It's a Ryobi 725r trimmer

    I didn't consider that, If it doesn't work by connecting the two parts together, I will use a gearing system to produce more torque.

    If I can get it to work, I'll consider that.

    Well, I guess the higher price is worth it, thank you. I'll give you all an update when I finish the project.

    I do know what an alternator is, but what I'm confused about is that could I find a one wire (with built in regulator / rectifier) one from the wreckers (I assume a scrapyard) for an affordable price ($30-40) just as I could with one without a regulator. I hope this clears things up.

    I considered using a self regulating alternator (one wire I believe), but I found them to be prohibitively expensive. I found one with a 3 pin regulator port and an external regulator for only $47 total. Would that allow me to connect it directly to a battery and how would I wire it? Thanks for your response.

    I'm a bit confused by what you mean by "A little alternator from the wreckers." How much would this cost me?

    I've found a new problem: how do you bypass the 3 pin regulator port? A mechanic told me it won't produce electricity without a regulator.

    I found a new problem, do I have to buy an external regulator and if so, how do I wire it to the battery.

    Oh, I didn't think of that, thank you!

    Okay, but where would I find such a shaft?

    Thank you Verence. I was wondering however: if I did a gear system, wouldn't the higher rpm on the generator produce more electricity? Or is there no difference?

    Along with my initial reply, I have another question. I found this alternator online. Where would I have to connected it to a battery and with that plug I circled prevent it from working?

    I actually don't know.
