My Pedal Assist Bike

My neighbor's kid had an electric motorcycle that has been sitting idle in the backyard for awhile. The bike ended its life after the speed controller gave up. The cost of the part could not justify the  use of it. One thing is he already outgrown the toy. I decided to give it another life in a different form.

 Trying to salvage the main frame. 

 Added a small basket to hold the battery.

 I used two swivel casters, one caster I have to bore the middle part.

There you go as it is almost completed.

My Cassette Radio To Iphone Conversion

Here is an old Radio Shack cassette tape recorder that has been lying around my house. 

 The back information says it uses a six "C" cell batteries.

 

 

 Exposing the circuit.

 

 I removed the unwanted cassette mchanism.

 

 I then soldered the speaker cable to a low impedance circuit. 

 Using the touch method, locate the input circuit. This should be somewhere near the cassette head connector. When touched, it should not create a loud humming sound than the rest of the circuit. You can series a capacitor to be safe.

 Short together the main power and the motor power.

 

 Add an on/off power switch.

Just like the simple toggle switch above which I super glued from the inside.

 

And presto! There goes my Iphone radio.

 

Bicycle Exerciser Generator

 I was able to salvaged the dynamo from an exerciser bicycle and installed it on a 20 inch bicycle. With this configuration, I was able to pedalled with less effort outputting 2.5 amps, 14 volts to my 10 ampere sla battery.

 Another modification, less gear ratio but outputting less ampe rating.

 

Let's Beat The Heat

A neighbor was on his way of trashing his old ice cooler. Although it is quite small for the idea, I managed to cramped the fan and battery in the cooler. After stocking a couple of frozen water bottles in the cooler, it was an added relief on one hot summer.
And it really works!

 It is much easier to bore a hole using the Dremel tool.

 First test on the cooler with the fancy fan.

 Here comes the modified one with a more efficient fan. The fan specification: dc brushless, 12V, 0.30 Amp, model D12SH-12.

 A look on the battery arrangement.

 The oposite side of the fan, outgoing flow.

Now add that frozen bottles and you will be blowing that cool air.

Angle Grinder Stand

Here are some snap shots of my homemade angle grinder stand. This tool aid gives a lot of benefits on different applications in optimizing the use of angle grinder.

 Plate from scrap metal.

 Taken from the rear.

 Now we see how the angle grinder is inserted to the pipe.

 Putting to a test the homebuilt stand.

 Here is one model on the market.

...and here is another made.

Press Brake

Once again, I used angle bars from bed frames

Added a car jack

I found some 1 1/2 steel bars from ukay ukay

Solar Bottle Bulb

You may have previously heard or read this before. Due to its practicality, its cost, materials availability, the effect that is impacting our daily lives, I am delighted to spread this idea.

As those wise men keep saying, necessity is the mother of inventions. The electrical shortage and increasing cost of electricity, the solar bottle bulb technology was born in Brazil invented by Alfredo Poser in 2002, a mechanic worker looking for a way for a substitute to electricity light using bottles of water.

This simple idea, a solution to energy crisis took many years before it was realized, implemented and spread to the world and at last, it's here in the Philippines. A Liter of Light (Isang Litrong Liwanag), proposes an alternative solution for household electricity dependence and open flame fire hazards using the natural source of light - The Sun.

The lightning project will use the solar bottle bulbs made from recyclables 1.5 Liter PET bottles, filtered water, chlorine and salt. This will cost approximately P50 to make 1 piece and will save at least P500 monthly electric bill. It will also save our planet earth from global warming, preventing climate change. 1 solar bulb would save 17 kg of carbon dioxide in a year. Imagine a millions solar bottles installed in household throughout our country and the whole world.

A Liter of Light is the latest project venture by MyShelter Foundation established by Illac Diaz to create a system of sustainability and reliability through its capability building and employment generating projects. The project aims to light a millions homes in dispriveledge communities nationwide in 2012.


Philippines Guinness World Record for Most Solar Bulbs installed in a day

Last Nov 30,  11,300 solar bulbs was installed by Rotary Club District 3380 and Armed Forces of the Philippines (AFP) in low income communities in Metro Manila to break world record for the the most installed solar bulb in 1 day set by Brazil which is 3000. Continuing for the project, 100,000 will be installed in Cebu this December and another 107, 000 solar bulbs early next year which marks 107th anniversary of Rotary Club District.


How to Make a Solar Bottle Bulb

To make a Solar Bottle Bulb, you need a 1.5 Liter PET bottles, flat or corrugated metal roof, filtered water, chlorine, salt and sealant. This simple lighting technology is very easy to make. Just follow the simple steps below.

Cut a circular Hole in the metal roof, approximately less than the diameter of your 1.5 Liter Soda bottle. Make a small strips perpendicular to the hole for a better grip of sealant and the container.

Insert the 1.5L soda bottle to the metal roof up to 1/3 of  its body and apply sealant around the metal strips. Let it dry.

Filled with filtered water. Water should be free from contamination to be able to reflect light perfectly. Put chlorine to resist the growth of algae, moss or any microorganisms.

Installed in your roof. Apply sealant for waterproofing.

Solar Bottle Bulb works by refraction of light rays because of different medium, air and water. By refracting light from the sun, it produces light 360 degrees around the room with equivalent light power of 60 watts bulb. It will last for 5 years without maintenance and before the water has to be changed. The chlorine prevent the growth of microorganism and maintain the clarity of the water.
