    Kenwood KDC-C800 Wiring Diagram

    Can I somehow plug just some pins to conect a Diskman in the CD Changer slot, this way the radio will "read" the Diskman to the speakers???

    Adjustable Strobe Light

    I found these options: http://www.hut.fi/Misc/Electronics/circuits/strobo_12v.html 12V stroboscope http://www.aaroncake.net/circuits/inverter.htm 12VDC to 120VAC inverter

    Adjustable Strobe Light

    http://www.electronics-lab.com/projects/motor_light/005/ This project is designed for 120V, but I intend to use it in my car. What happens if I use the 12V battery? Is it a good idea to make the 12V become 120V??? If it is, how can I make it? Tks in advance, Christiano.

    22 Watt Amplifier

    That's why I love smart people... eheheh... I'll biuld a FM transmitter... Is there anyone that you recommend?? I've found this one...: http://www.electronics-lab.com/projects/rf/023/index.html Is it good??? Tks in advance, Christiano.

    22 Watt Amplifier

    I don't have another amplifier for the speakers.... Only the stereo... I was going to plug the output of the device directly on the wires that go to the speakers.

    22 Watt Amplifier

    Did someone build this?? Does it work well??? How loud can 22 Watt get??? Enough to increase a discman output into an auto's speakers (Two 200W, 4 Ohms Pioneer, on the back)? If not, which device should I build??? http://www.electronics-lab.com/projects/audio/006/index.html

    Inductor

    I'm trying to build the damn TV Signal Amplifier but it came without some important information... Like the lenght of the Inductor or its inductance... I am assuming that its lenght is 0.72 cm. ( Number I came through an insane proportion of sizes from an image of the circuit that I'm trying)...

    Inductor

    I just can't find an specific inductor... It only says that it must have: Diam: 5 mm Wire: 0,5 mm Turns: 8 What should be it's inductance??? How can I calculate it??? Can I replace it somehow?? With some resistor, another inductor, ow something?? Does the distance between turns...

    TV Signal Amplifier - Part II

    Just for the record... The HOT is the inner copper cable and the SHIELD is the outer silver twisted wires, right???

    TV Signal Amplifier - Part II

    http://www.electronics-lab.com/projects/rf/003/ TV Signal comes by a coaxial cable, this way, there are 2 wires... I can see where the C5 is, but where is the d**n input?? Is it the nr. 4 and 5??? And what about the output???? Is it the nr. 1, 2, 3 or 6??? This schematic is well drawn, but...

    TV Signal Amplifier

    As we can read in the image above, there is only on Trasistor (TR), but, at the schematic page smrtkit lists 3 transistors (BFR90, BFR91, BFW92). I'm a newbie in electronics, and although I notice they are diferent, I can't understand what is this diference... Datasheets: BFR90 BFR91 BFw92
