    0-30V Stabilized Power Supply

    Well Tompa it is dificult to help you from here, maby you should check your output tranzistor/tranzistors, i watched the video and your P.S worked then just fine, check for any wires soldering joints wich might broaken during the instalation of your P.S to enclosure.

    0-30V Stabilized Power Supply

    Let me inform you that i have changed the value of R17 from 33 Ohm to 47 Ohm, and now  the warning LED of an current limiter does not light when there is no load, thank you Audioguru. Your video shows that the warning LED lights when there is no load and the current-setting pot is turned down...

    Led display Digital Voltmeter question

    Yes i have build it , and according to IC  datasheet, actually i have build it 2 of them one will ICL7107 Maxim Dallas production and one with INTERSIL ICL7107 they are both working good as long as I'm supplying them with 9 volt battery  , only I'm having problem when I'm supplying them through...

    Led display Digital Voltmeter question

    I have built the voltmeter and it works O.K when I'm supplying it with 9 volt battery, but when I'm supplying it with 7,5 volt transformer and a rectifier bridge with 4X1N4007 diodes as a rectifier bridge and 100mF capacitor the last digit is going up and down, in other words voltmeter becomes...
