  1. if the input is 5.6v will it read 5.6 or only 5????
  2. 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???
  3. Does anyone have the wiring diagram for the 13-pin cable of the KDC-C800 Kenwood CD Changer ??? Tks, Christiano.
  4. 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
  5. 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.
  6. 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.
  7. 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.
  8. 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

    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) This way, using Quantum's equation: (8^2 * 0.05^2) / 0.0072, resulting ~22 I will assume too, that the distance among turns is 0.

    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 affects the component??? Tks, Christiano.
  11. Just for the record... The HOT is the inner copper cable and the SHIELD is the outer silver twisted wires, right???
  12. 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 without some important information... Tks in advance, Christiano.
  13. 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
