  1. Alimentator 0-30V 10A

    Pentru laboratorul vostru, am atasat o sursă de alimentare cu LM723, capabil sa livreze o tensiune de ieşire ?ntre 0 şi 30 V cu un curent maxim de 10 Amperi. Sursa este protejata ?mpotriva scurtcircuitelor şi permite ajustarea completă a pragului de protectie de la 50 mA la 10 A. Tensiunea continua este filtrata de condensatoare cu o capacitate de circa 20.000 uF, iar pentru semnalizarea prezentei puterii de RF pe linia de alimentare sursa a fost prevazuta cu un indicator. Cu ajutorul potentiometrului P1 se regleaza tensiunea de iesire.
    OBSERVATIE!!!! Dioda D3 din imaginea cu amplasarea componentelor electronice pe cablaj este montata pe dos.

  3. Detector de metale

    Un detector de metale pe care l-am vazut in revista Nuts and Volts si care are in componenta doar 4 tranzistoare 2N3904. Schema se remarca prin simplitate si printr-o eficienta destul de buna. Cititi documentatia atasata pentru ca daca va intereseaza sa construiti un detector de metale simplu, iata un articol care va poate ajuta sa faceti asta. Spor!

  18. Symmetrical supply in cars

    There is a problem if you want to use a car battery to power a circuit which requires a symmetrical supply voltage. Having abandoned the idea of mounting a second battery in your car for that purpose, take a serious look at the circuit discussed here. It converts the car battery voltage into symmetrical ?12 V or even ?15 V rails. Since the converter is able to supply a continuous output current of about 0.5 A, and a peak current of up to 1 A, it is eminently suited to powering control amplifiers and small power amplifiers.
