This video from pedalpowergenerator.com shows one way how to install a charge controller for your battery powerpack. This video is a great intro to people who have never cut a wire, and used crimp on terminals before. The charge controller makes sure that you don't over charge a lead acid battery. It can handle up to 25 Amps of current and can withstand up to 120 Volts input voltage.

Here is another FPV flight with my sub-micro (AUW 50g) setup. This time I tested a 350 mAh battery. It gives me roughly 5 mins flight time. It is ok because it seems that range of my 10mW video transmitter is roughly 50 meters - maybe a little bit more if there are no obstacles between the heli and the base station. There is a 10 mW 5.8GHz video transmitter & 1g PAL video camera with a wide eye lens in my heli. I try to save veight using an one lipo setup and a 0.6g 5.0V Polulu voltage regulator for filtering interference from the motor & ESC. Receiver's antenna is an omi-directional 5 dBi whip. Here is a link to my setup: helifreak.com www.rcgroups.com

Chicago Electric Power Systems Article link: www.driverstorer.com For use with auto, marine, ATV, and other trickle charge applications Don't forget to hit subscribe! DS briefly runs through a series of current and voltage tests on the Harbor Freight 1.5 amorphous watt solar battery charger kit. The harbor freight amorphous solar battery charger kit includes: *One mountable solar panel with hard plastic bezel measuring 14-3/4" L x 6-1/2" W x 7/8" thick *Detachable vehicle adapter with activity LED (12V) *Documentation Formulas used to calculate the wattage from the solar panel: Variables: V=Voltage I=Current R= Resistance W= Watts V=IR (ohms law) (to double check calculations) W=(I^2) R (reads: (watts = current squared * resistance)) Current measured (100 ohm resistor in series) 25 -- 35 mA Output wattage calculated in overcast skies (100 ohm resistor)= W@ 25mA= 0.0625 (62.5mW) W@ 35mA=0.1225 (122.5mW) W@ 120mA= 1.44 Assuming you reach the advertised max current from the solar panel of 120mA you seem to max out at 1.44 watts theoretically. This is close to the 1.5 watt rating of the solar panel, but slightly less. As a vehicle battery trickle charger, the Harbor Freight 1.5 watt amorphous solar panel- solar battery charger kit will work as advertised, however local conditions will always affect the efficiency ...

HOW TO USE AN LM317 VOLTAGE REGULATOR TO POWER ANYTHING U LIKE OFF ADAPTORS AND 12V CAR BATTERIES

The project is essentially done and ready for delivery to the strawbale home where it will live. The only thing to add now is a bit of + / - physical protection to avoid bumping live buss bars, a small AA charge, and a lamp. This setup will basically be used to run a few kitchen appliances like food processors, etc, in an off grid home. When the SLA's die, each one (5 total) will be replaced with (2) 6V Trojans in series, thus comprising a 1000 Amp Hour Bank. That is why everything was done beefy, to accomodate that. I will post links to the parts I used; everything was quite affordable. The setup as shown cost less than $300 incl. everything you see. the inverter is a Xantrex 3000 watt modified sine wave with max 300A input.

This gun is now for sale: I hardly used it after the tuning while moving my attention to airguns from bb. Please email me at markqian@hotmail.com if interest. Here are the modification I did on this gun: 1). Replacing the barrel with JC. This is the first modification I did. It sounds easy but not really to me when I was really new to the gun. I eventually ended up with disassembled the gun completely. The good fact was that it resulted me understand more about the gun. I have been reassembled this gun for more than 15 times. Disassembling the gun not-intentionally encouraged me go further to replace the chip. 2). Replacing the chip for full auto. This is also a hard one. After disassembling the gun, I came up with the idea of replacing the chip. It looks straight forward in the demo video but it is harder when you really do it. You could over heat a component or permanently cut out part of the circuit - I did and make it up when soldering. Warning: anything could happen after you reassembly your gun...What happened to me was the magazine was no longer working. It first kept loading as long as the power is on without stopping and eventually stop working/loading completely (lost all the power). I got it fixed by getting a chip replacement (thanks for DrozdMax.com with a free replacement). 3). Using 2 x 3.6v (close to 4v when full) + 4 x 1.5v batteries = 14v. This is the easiest task. You just need to decide what voltage you want. I don't want to get too close to the limit ...

UPDATE (9/12/11): When actually implementing the circuit in my laser project, I uncovered several problems. I was going to have the output connected to a voltage regulator inhibit pin. Because the datasheet was so vague, I thought that the regulator was off when that pin is high. I was wrong. I had to place a mosfet on the output to invert the signal. Doing that caused another problem. The opamp's output voltage was too high (~2.5v) in the off state causing the mosfet to stay on. I had to increase the resistance on the feedback which also required that I change the resistor for the zener diode. Note that different opamps can behave very differently based on their specifications. Be sure to use the same opamp in your final build as the one you used for testing. LTSpice schematic files can be found on my blog: patheticcomputing.com In this video, I explore several different circuits and solutions to the problem of low battery voltage cutoff. I also explain zener diodes, Schmitt triggers, and hysteresis. Near the end of the video, I show an actual breadboarded circuit and show how to find the correct resistor values through experimentation.

The magneto alternator of Royal Enfield Motorcycle UCE EFI G5 has 18 coil 3 phase stator that charges 12 volt battery. The alternator electric output is directly affected by the speed of motorcycle engine (rpm). Alternator generated AC of 15 volts when engine was running at idle and it increased to 40 volts as throttle was opened to high rpms.
