    $4 Solar Battery Charger

    Ok, also if I stepped the volts from 4v5. to 3.6 v to charge 2 batts or something like that, could I get more mA current, charging the battery faster?

    Ok, I have a 4.5V Panel at 200mA, about 1W, and I only had 2 NiMH triple A's connected for charging. I realized I did the diode on the wrong side, but was confused because I guess the Positive side of the battery actually has the most Negatively charged particles (sigh..lol) so everything I read prior about current flow direction was misleading to the project.Soo, I set the diode on the pos terminal of the panel facing toward the battery pack (I guess about 2.5-2.7v) and It didn't die, but didn't seem to charge after a couple hours in the sun.Is there a way to directly check if the current is flowing into the batterie's + terminal?

    Thanks. Is there a difference between GND and NEG or (-) terminal?

    Can someone explain this better? How do you connect the header and why would that make it so you need only one pin? Are you making a microcircuit in from that single line?

    I have been struggling with this forever. All I want to do is use my 5v panel to charge my 1.5v NiHM triple A batteries. Seems like it kills every battery, they start out low at 1.0V and then after I use the panel with + to + - to -, with a diode on the negative lead.What am I doing wrong?

    Yep me too

  • Old PC Fan ----> Wind Turbine in 10 Minutes

    What kind of voltage did you record and mA output?

    You totally can. You have to test the voltage and amp output, but you can certainly string the same size fan together in series or parallel to achieve your desired results to break the resistance threshold, etc. :) Happy Energy!!

    I believe this fan would create DC current, and your phone charges on DC current as well. Wall chargers take in AC and convert them to DC so that your phone can use them, but PC's usb output etc all is in DC, including the usb portable battery chargers etc.

  • How to make a small wind generator (In celebration of earth day!)

    Hi, this project is awesome and I am going to test it out very soon. But to answer your question, if you already have set this up, connect the power lines to a multi-meter. From there, scroll through the voltages and you will find the correct setting to detect it (if using a digital standard one), and it will tell you the voltage. It should also be possible to detect the current (the mA output) of the "turbine" as long as it is spinning with the multimeter as well.Trust me. The multi-meter is worth it! (and like 5 bucks)!
