In this thread you can share something about your electronic project. Moreover this is a general thread on electronic projects so you can share anything on schematic diagram and some important details like layout and fine tuning and some do's and dont's. ( speaker system and box and specifications and materials used and preamp and other electronic devices) ....





Special thanks to my brother who shared some details.

His project was all about a mosfet amp which can operate with a power supply plus and minus 25 to 50 volts using a minimum of four mosfet output devices per channel. The schematic diagram will be posted as soon as obtained.

Well I had this high school project for the Science Fair developed by me and 2 of my mates. It was a solar-powered inspired wristband which aims to carry portable energy for a 1.5 - 3 Volt appliance or gadget like your Walkman and CD player.

The objectives that the proponents of this study are as follows:
~To have a portable source of energy for an appliance that requires at least 1.5 - 3 Volts
~To be able to construct a device which is cost-effective and would last more than batteries (rechargeable or not)
~To be able to utilize an energy source which has minimal to completely nonexistent environmental effects.

It took us more than 3 months to develop the project due to scarcity of materials and we had to have a solar panel which fits our criterion of it being small. The project came through though, and it was a success. still, there was a downside to it, you had to have adequate sunlight for the gadget to become functional, which presented a huge dilemma since the construction of the said project was in time with my country's rainy season.

I have the schematic diagram and a sketch of the prototype somewhere in my closet...

I turned on a light bulb with some batteries. That's as big as it gets for me. =^__^=

not interested in electronics, though some of my mates attended robotics contests in Shanghai, Taiwan etc.

this was our project:

to make a vase out of woods

and attached a bulb into it.^^

that was pretty hard...

i remembered that i was the last person

who passed that scary thing..

<btw if you're bulb is not fully attached,it might explode,

and that's happened to some of my classmates..poor them>

I tried to make a robot once, but never got around to giving it legs... Also, the fact that it was made out of foil paper and paper clips didn't help it achieve glorious life! Then I turned 6, and decided to cut my loses and move on to better things.

I made an igntion coil driver out of a 555 timer and fed it into a voltage multiplier for about 100,000 volts.
ran off of 12 vcd consumed about 8 amps and was good for about 4 inch arcs, was loud tho.
