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.
Hello Instructables CommunitMe and my dad have made working generator! It made be crude, but it does produce over 12 volts of electricity.
Make an Instructable out of 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.
im going to be a negative nancy, but those trimmer heads dont have a whole lot of torque to spin a alternator/generator, especially if you put an electrical load on the system.
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 hope this clears things up. Sorry about the bad wording of my previous reply.
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?
1. Would such a combination workIn theory: Yes, why not? In real life: Yes, maybe. 2. Would it be best if I directly connected the engine to the alternator with no drive belts or chainsYes. Any kind of gear system / belts will waste some energy. Unless they are needed to match the optimal speeds of engine and generator. 3. What is the best way to connect the two? As direct and as short as possible. Or, if you need gears / belt discs - as few as possible.4. Where should I remove the engine from the "trimming part". As close to the engine as possible - or as close as you can manage with the knowledge and tools you have access to - you didn't tell us about that.
A gear system will not change the energy. You can only get higher RPM - with lower torque, or a higher torque - with lower RPM. The power is always the same (minus the losses in the gears). But your generator may have a sweet spot (frequency), where it converts more of that mechanical energy to electrical energy. Same, your engine may have a sweet spot where it runs most efficiently. If those RPMs are too far apart, a gear system is a good idea. You can never get more energy out than you put into the system (in form of fuel), but you can minimize the losses in each step.
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.
