Datasheet Bank

Often times looking for a datasheet becomes a bit problematic, so I thought I would gather a bunch of them and put of them into one place for easy and hassle free access.

Note that even if the part you are looking for is not listed here might still be in the Datasheet Bank. I will keep on updating the list and also the bank as much as I can.

Simplest Sound Reactive LED

This one is a good project for using with audio system or on the back of a TV. It will add some effect to the environment as the LED will keep on dancing with the Sound. The diagram will be very minimum so a very small amount of component is needed.

Parts List:

Transistor:
1 TIP35C with Heat sink.

Resistor:
1 22Ω
1 100Ω

LED:
5 LED of same Color.

Diagram:

 

Note:

1. You can use an OP-AMP as buffer for the input.
2. More LED can be used as well but you have to change the input voltage and current limiting resistor for that.
3. For parallel connection same colored LED has to be used as different colored ones usually have different forward voltage drop.

AM-FM-SW Antenna Booster

If you plan on visiting someplace where AM-FM-SW signal is really poor you can make a simple circuit that will slightly boost the signal so that you can get a better reception.

Components Needed:

Resistor:

1 1MΩ 

Capacitor:

2 470pF
1 0.47µF

Inductor:

1 470µH for AM
1 20µH For FM/SW

Antenna:

18" Telescopic

Battery:
9V PP3/6 AA.


Diagram:

   
Note:

1. Place the 0.47µF capacitor as close as possible to the Inductor.
2. If you can't find the MPF102 use any medium power NPN RF Transistor.
