    Electronic Circuit error

    Works now problem was the IC was burnt and that i only had to move the lower alternative on track to the right

    i did continuity test nope and it is my 2nd time and i have this problem 2 times a row let me check and write back

    Electronic Circuit error

    im sorry if im annoying if you dont have the patience to help then just stop replying this thread i dont wanna beg but the only problem i got from this thread so far is the led problen which i fixed by moving to the e line in the breakboard.For the schematic i posted it in one of the comments...

    there is already watch the circuit there is 3 points with number 1,2 and 3

    Electronic Circuit error

    i moved the end resistor lead from d21 to e21 and d22 to e22 basically i i removed everything from the d track except the diodes and moved resistance lead and led lead to the e track There is no schematic for the power supply just a bridge a 7812 voltage regulator a 1000 micro farad 50 v...

    I moved the resistance one round lower same for the led so that there is no direct connection with the ac supply(~) but the transformer is still sending out 4v instead of the expected 14v there seems to be an error i checked all the diode capacitor etc... It is the 2nd time i made this circuit

    There is a cross that separate the 2 ~ there is no zener only a 7812 voltage regulator with a capacitor and at the end a led to check if it is working or not.The circuit down i think doesnt matter for now because the power supply itself wont work

    it is a step down 12 v transformer the ~ icon get the 12v from the secondary winding of the transformer which means transformer output there is a cross between the two input meaning i cutted the track there. I can remove the red tracks but it wont change anything because there is nothing there

    Electronic Circuit error

    Hello i have to build this circuit where you see the ~ icon it is the 2 input from a step down 14v transformer.When it is disconnected the transformer give 14v, when it is connected it gives only 4v there should be a defect in the circuit can someone help me find it please?

    Need to build a circuit + Power supply check plan for me

    Harald i think there is a misunderstanding in reality the resistance+led didnt work because the copper tracks were oxydated and didnt let current pass.

    Abou About this do you think you could explain it to me a bit better why? And yes i realised a big mistake totally forgot the +Ve and the -Ve when i checked the ic info sheet :confused: Im gonna fix it and try it again but if there are others mistakes i would like to fix them.:)

    Need to build a circuit + Power supply check plan for me

    A bit late but i assembled the track it doesn't work sorry im naturally a bad drawer but i think it should be easier to understand I dont wanna use something else than pencil for now because im changing it each time :P
