Since i have been reading about Peta, vegetarians, and animal slaughtering i wonder if any parts of an animal can be used as electronic parts. If their is i hope the Peta people will stop watching TV.
Could the fat be used in making electrolytic capacitors?
This is simpe explanation on how to read the most types of capacitors. Before you read a capacitor, you should know about capacitor’s capacitance value (farad, microfarad, nanofarad, picofarad).
This image explanation is very easy to understand, just click the image to enlarge and then save the image for future reference. Or download the picture here. You should be understand about how to read capacitors after looking the picture.
This amplifier circuit design is based on the 18 Watt Audio Amplifier, and was developed mainly to satisfy the requests of correspondents unable to locate the TLE2141C chip. It uses the widespread NE5532 Dual IC but, obviously, its power output will be comprised in the 9.5 – 11.5W range, as the supply rails cannot exceed ±18V.
As amplifiers of this kind are frequently used to drive small loudspeaker cabinets, the bass frequency range is rather sacrificed. Therefore a bass-boost control was inserted in the feedback loop of the amplifier, in order to overcome this problem without quality losses. The bass lift curve can reach a maximum of +16.4dB @ 50Hz. In any case, even when the bass control is rotated fully counterclockwise, the amplifier frequency response shows a gentle raising curve: +0.8dB @ 400Hz, +4.7dB @ 100Hz and +6dB @ 50Hz (referred to 1KHz).
Loudspeaker anatomy:
In this document, we use the terms ‘loudspeaker’ or ‘speaker system’ to denote a unit consisting of one or more drivers in an acoustic enclosure perhaps along with a frequency selective crossover, tone controls and switches, fuses or circuit breakers. Connections to the amplifier or receiver are via terminals on the rear.
The front is covered with an (optically) opaque or semitransparent grille which provides protection and improves the appearance (depending on your point of view).
A ‘driver’ is the actual unit that converts electrical energy into sound energy. Most drivers use voice coil technology: a very low mass coil wound on a light rigid tube is suspended within a powerful magnetic field and attached to a paper, plastic, or composite cone. The audio signal causes the coil to move back and forth and this motion causes the cone to move which causes the air to move which we perceive as sound.
You’re a newbie in electronics and you need to practice your electronics knowledge and then I suggest you to build this LED Flasher (Flip-Flop). This circuit is very simple and very easy to understand…
INTRODUCTION:
Flashing circuits are very interesting. They grab your attention and can be used in many applications. They consume very little energy and a single cell can last as long as 12 months. This is the simplest circuit capable of alternately flashing two LEDs.
