Human/Bike Powered Electric Generator

Loki, I hope you don't think I was knocking your design. I wasn't at all. I love it when people build things with what they have already around.
I only showed you mine to give you an idea for using the power you're already making and also to show yopappaman, with his "I really don't think you want to even try a dc motor as a generator." statement that you can indeed use dc motors with great success.

Good luck with yours!

Important question. Could I splice this lil sucker into my Dark Green field generator driver. It's a Micro indicator lamp. 12V, 35 mA. 0.12" / 3.0 mm diameter.)

Still need help with this question... :D
 
Check out this wiring diagram i whipped up u guys. What do you think?
(Nvm I reversed the order of the components on the Field Driver wire. I'll fix it.)

Wrong

Hmmm, I dunno about that...
What version? :D :wink:
 
I started with ACad 2.5 when it still fit on floppies. :shock: :? :D
The first version I bought was R9, and the last is the one I still use, 2000i; It's good enough for what I am doing. I just cain't see payin' $3500 every three years to a service contract. It's great for 3D modeling, animation, all my drafting needs; it taught me the power of programming (LISP; the first language that I mastered)... heck it even landed me a contract with Microsoft back in '93. A very useful tool ~ if it wasn't so expensive. :cry:

Sorry, not meaning to hijaak this thread...

What's the story with the LED?
 
Np. And I just looked up ACad 2011. 5000$ for the crappy version lols.

I think it's a regular bulb (Idk?) , I have a link to it a lil ways back in the posts.
When I start pedaling energy will flow from the battery to the rotor and creates an elctromagnetic field so the alternator can do it's thing. Once it becomes self sustaining the alternator will use it's own energy to make the field and should quit drawing energy from the battery and the light bulb will turn off.

So in short the light bulb (Or LED?) is so I know when the alternator becomes self sustaining. Some cars have lights in their circuits too.
 
Idk, but I actually was gonna use the lights resistance for the total... How do I know how much resistance it'll provide?
 
http://www.csgnetwork.com/ohmslaw.html

It says 34.285714285 ohms. I figured I'll try it like this (68 ohms total resistance wired in) and adjust it as needed. Too much resistance can't really hurt the alternator, but too much can.

I think you missed it by a decimal point.

I calculated 362Ω @ 12.67v.
A tungsten filament has a 15 to 1 resistance ration. i.e. resistance of the bulb when lit will be around 5.4KΩ
 
Maybe I will wire it parallel and just wire a 3rd 22 ohms resistor. Will post a new schematic shortly.
Gotta go marinate some chicken :p
 
Pretty version!!!
Red = Resistors
Light Blue = Positive Wires
Orange = Negative Wires
