This is a review of a school project I assisted with. It's an "organic" solar powered LED chandelier made from dried branches. I also demonstrate the power output of several small solar panels in the morning sun. Equipment used in this video. * Digital Multimeter * WellSee MPPT soalr charge controller * 5 watt amorphous solar panel * 5 watt multicrystalline / polycrystalline solar panel * 6 watt GSE / CIGS / thin film solar panel * 6 watt monocrystalline solar panel * 6 watt HQRP flexible monocrystalline solar panel * Yebo electronics voltage regulator, LM317 - www.fort777.co.za

A simple useful implementation of the low powered toroid oscillators shown recently. 3x 1.8W solar panels are connected to a rejuvenated car battery (was completely dead, sat outside for a couple of years and a homemade Bedini wheel knocked the sulfation off). The battery connects to a LM317T circuit, which converts the power to a constant 1.2V. The circuit is within the datasheet.for the LM317T. Out then, to a 1200 turn approx 1" ferrite toroid, with approx 70 turns as the Primary. A 2SC2655 then supplies the switching to power the mains rated LED night light. The light can be left on 24 hours a day. It uses only 5mA. The best running brightness can be regulated with a pot on the LM317T circuit (20K). The 3 homemade battery cells run 'Penny' oscillators, see Lidmotor's channel for the circuit diagram for that circuit. Note - Zinc Oxide not magnesium oxide is used within the seashell cell. All 3 were stovetop type cells, see IBpointless2's channel for a video where he shows how to cook down the ingredients

Here is me showing off my newly made, custom PSP charger, and the schematics for the soldering. I used a 7805 +5VDC Voltage Regulator (1 amp) Radio Shack part # 276-1770.

This is a DIY solar powered USB charger with schematic that you can build to charge your ipod, blackberry, iphone, camera, or any other electronic device that you can plug into a USB port. There are 2 (in quantity) 5 volt solar panels connected in parallel to a 12000 uF capacitor. The positive is then connected to pin 1 of the voltage regulator (low dropout), pin 2 connected to ground. Pin 3 and ground are then connected in parallel with a 470uF cap, which is then connected to the USB port.

First of all, for the observant I must say that I did use a non deepcycle battery, but it was free and this project is still at the experimental stage, I'm not even sure how long the brown wooden box will last or the handheld generator or those kitchen spoons, but time will tell. This run of the river project is insanely inefficient mainly because of the half inch hose, which should really be 90 feet of 1 inch PVC, but the materials were easily acquired and installed. After I've watched this project for a while I'll more than likely upgrade the main components as they breakdown. Also it's really important to add a fuse or a low amperage breaker at one of the battery terminals simply because the odds of a mouse chewing through the wires or a tree falling over them in the next 10 years is huge. Most of these batteries can put out enough cold cranking amps to catch any log cabin on fire or create a forest fire. The hand generator only makes about 3-5 watts of hydro electricity per hour and therefore does not need a voltage regulator but is just directly hooked up to the 12v battery and functions very much like a trickle charger does. A DC to AC inverter may be hooked up to the battery terminals if you want house voltage, though I recommend attaching a switch to it in order to turn the inverter off when it's not being used in order to save power. The funny thing is that most of my electricity needs are 12vdc, including that 13watt CFL bulb so I might never hook up the ...
