    LC Metre

    Anyone tried to build the "LC Metre" from site's New Links? http://xavier.fenard.free.fr/LCMeter.htm I breadboarded the logic circuit and tried with LCV100803.HEX(flash), LCEEV100803.HEX(EEPROM) files for the AT90S2313 u-C but the LCD works funny. It displays only the first 8 characters from...

    4W FM Transmitter

    Sorry for that folks. The original text was in Greek and it did made sence back then. The text in the above web-link was translated to English using a PC translation utility which doesn't understand electronics terms such as Ohm and Farad. :P As a result the reading and understanding of the...

    TDA7000 FM Radio with BB204

    I don't have the specifications for the varicaps. You should find them and check if they have similar capacitance vs reverse voltage curve. The next step is to play with the coil. There is no need to keep it in form, you can stretch it, pull it, push it, put a nail in it, make it an ugly thing...

    0-30 Vdc Stabilized Power Supply

    24V AC is a standard Voltage Output of common transformers, that's why this circuit was designed for this voltage. A few volts up or down(maybe +-5V) aren't going to produce any fault but it is recommended that you use a 24V AC transformer.

    capacitance meter

    No, this circuit cannot measure ESR. You can find circuits for this purpose if you search the internet. Some of them are offered as kits. Some months ago(maybe 1 year or so) Elektor magazine published an article including all the schematic, PCB etc of an instrument that could measure ESR onle...

    how real is it to power an inverter of 1.5kva with a solar panel

    If you want to raise the voltage to 110V AC or worse to 230V AC, you will -for sure- be out of current(depending of the voltage output of your panel). You have to connect many panels together to achieve your goal. But it should not be a simple connection :-\ Kyriakos

    FM Radio

    Ok, you may use it as a simple analog radio receiver ;) About the other matter, the "low-high pass", I can only guess for what you are talking about. I think you mean "tone control" which suppress or raise the low-high frequencies of the acoustic bandwidth. Well this receiver doesn't have any...

    FM Radio

    Hello EDY, you are correct. IC3 and its complementary componets are a just a sound amplifier and can be ommited. You can put the sound signal (taken from potensiometer's P1 wiper) directly into your's soundcard AUDIO input so that you can have totally digital control over your radio receiver...
