safepages.org Homemade Solar Panels - The best guide! Click the blue link to watch the presentation. The link above will take you to the presentation video for Earth4Energy which is currently considered the best guide for building your own solar panels. Read below for more information about solar panel systems... With the increasing awareness to promote a greener environment, using alternative energy sources like homemade solar panels are gaining in popularity. In fact, installations of these systems are increasing every year thanks to the various programs supported by the government. Examples of this are the Feed-in Tariff and the Renewable Heat Incentive scheme, which encourages the population to install homemade solar panels in their homes and buildings. Here are some of our "pros and cons" to installing a solar PV system: Cons Installing homemade solar panels requires an upfront investment with the prices depending on how large the installation will be. Return on investment for this system can take up to 6 to 10 years. Just like any other product, this system will degrade at approximately 20% over a period of 25 years. It requires more roof space to install the system. If we will look closely, installing solar PV systems has more pros than cons. Yes, it requires initial investment but over time, it will translate to bigger savings as it can help save on electricity bills. Aside from the monetary benefit, renewable sources of energy can greatly reduce the use of fuel ...

The turbine will be placed on my roof in a couple of month for maximum output... PS the only thing left needed is a 1.5 kw inverter connected to my main. (light only)

This is a video about my 3 homemade power supplies. All with adjustable voltage regulators.

Hey guys!!!! Thanks to Kipkay videos coz now i know how to build my own mini-fume extractor!!!...............This is my mini fume extractor that actually works!!!!!!! Ingredient to make it : computer fan carbon filter box battery voltage regulator small wire gauze some wires soldering(important) Thanks again Kipkay!!!!!!!!

The wind turbine uses a stepper motor. It will make about 5 watts at 100 RPM and at 3000 RPM it is still making only 5 watts. I will have to redo the LED's inside. I will ether try to add a resistor to it or I will add a voltage regulator to keep the voltage under 14 volts. The battery is 150 amp-hour.

This is my homemade miniature elevator controller, using relays! it drives a TEMIC 24VDC motor, and its runs on a HP 18V 1.1A power supply, from an junked inkjet printer. The motor runs on the full 18 volts, and for levelling it runs on 5 volts, using a LM7805 voltage regulator. the levelling switch will be replaced with some more microswitches when i begin building the real elevator shaft. the buttons are : up to floor 2, down to floor 1, emergency stop.

Homemade Power Supply This is also good for voltage regulation/stabilization of some "green energy" voltage sources that may fluctuate/vary a bit and you need a stable/steady voltage souce for a project. I will put more text here soon, and check often. The LM317 chip allows for a low number of parts (maby 7 parts, plus cords and.or boxs) to be required to make a fixed or variable voltage/power supply. There are similar chips and I will try to put some numbers up. The chip itself is fairly large - this is not a small IC chip that is difficult to handle , and there is only 3 large terminal pins that are easy to access and work with, and a hole for the screw/heatsink if used. For the power supplies in the video, the chip is rated at about 1.25V to about 25V and 1.5 Amps of Current. There are some LM317 versions that will allow more or less current also. You can get just about all the parts at Radio Shack, but their prices are high it seems. Radio Shack is good if you need something right away. You can order the LM317 IC chip from major suppliers, and on Ebay for a deal - some already heat-sinked on a board and ready to go. If you can pick up several at a time to save on shipping, etc. They are only about $1 US now. You can even use machine screws or speaker-jack screws for the input and output terminals. Radio-Shack also does have some nice electronic "kits" with easy hook up springs for the wires. These are the popular "100 in 1" or "200 in 1" , or "300 in 1" type kits ...

This is demonstration video of homemade red laser. It uses high power LOC diode, LPC-815. I'm using an LM317T driver to supply 410ma to diode and delivering about 200-250mw (or more, don't know) with acrylic lens in axiz module. This laser cuts, melts, burns and more. And beam is great !!!
