    Resistor Question

    I bought an assortment of resistors. They are different values, in individual packets- all nicely organized and labelled. Most say 10K or 660 R. etc But one of them says 6K8 what does that mean 68K? 68R? Neither? Thnak-you

    Wire

    Hi folks. I received my amazon order for enamelled wire. I bought a role of it, I think it is 28 gauge. It is blood red in. color, making it easy to see. I wish i would have known about this long ago. It makes connecting things so much easier and minimizes the chance of shorts. The only...

    Wire

    Thanks. So in practical terms, when I solder one end of the wire, it should solder fairly easily, but the remaining part of the wire will remain insulated? Forget this question. It was answered with the link you provided. Should have read that first. Thanks

    Wire

    Thanks. I think I will get an assorted kit for future uses, but I am intetrested in what has been said about magnet wire. What does solder through insulation mean? and how does it make the job easier? Thank-you to all by the way, I am located in Canada, Usually I can get many products via...

    Wire

    Can anyone recommend what type of wire to use for wiring components using solder on a circuit board. As you know, some wiring is very tight and delicate, so I am looking for something that is very thin and easy to use. Thank you. I plan to order it from Amazon

    Why is this Happening to Me?

    Thanks for the tips. I used L1 because that is the way the person had it labelled in their diagram. But point taken. Primarily, I built this to practice putting breadboard circuits on soldered circuits.

    Transistors

    Thanks for all the useful tips and links. This helped me a lot. For the most part the circuits I will be building are pretty simple. But it is good to know how to check whether I can get away with subbing out transistors and how to determine that. Thanks again for taking the time to help me...

    Why is this Happening to Me?

    Thanks for all the advice. I succeeded in building the circuit. Turns out I had a LED connected backwards. I am still getting used to reading schematics. In the circuit below, Where L1 connects to C1 and then also to Q1's collector, I had the positive rather than the m=negative of the LED...

    Transistors

    I have studied how transistors work as a switch or amplifier. Although I have not mastered it, I am getting here. I have a transistor related question. I bought two transistor assortment kits. One kit has 10 different types of transistors. They are: BC327 BC337 BC517. BC547. BC548. BC549...

    Why is this Happening to Me?

    Yes, I am not giving up. I am going to keep doing it until In find out where I am screwing up. On a more positive note, I told myself that I will not be looking at Youtube videos and simply copying circuits. So, I spent many hours over the past week learning Ohms Law, Kirchoff's current and...

    Why is this Happening to Me?

    This keeps on happening to me. I put together a circuit on a breadboard. I get it to work. I then try soldering it on a permanent board. Doesn't work. I am sure I screwed up along the way, and I know you can't help me as I have provided zero specifics, but my question is more general. Is...

    Picture to Circuit Board coding

    Thank-you. I have a number of boards that are included as part of electronic kits I have ordered. Thus, they are all slightly different. Soem have the problem I have described, while others do not. To be honest, it is not a big problem. I was just wondering about the "why" . Thanks to everyone.

    Picture to Circuit Board coding

    I guess it is an error in production , because I have other boards that do not have this issue. Being new to electronics, I just wanted to know if this truly was an issue, or if there was any logic behind it that I was missing. P.S. Thanks for your patience. I do appreciate everyone on this...

    Picture to Circuit Board coding

    Once again, sorry for the issues. I have taken new photos. To illustrate my point: You will notice there is a resister lead on K1. You would think that if I flipped the board around and found K1, it would match up to that very same lead. But it does not. You will noticed that K1 on the flip...

    Picture to Circuit Board coding

    Sorry- I did not realize that providing a description and not a picture was causing so much angst. Here is the board I was referring to in this thread, https://www.electronicspoint.com/forums/threads/circuit-board-coding.292865/ Apologies if anyone got upset.

    Restore/Repair and old Radio

    I used a spray that is meant for electronic components. I purchased it from Radio Shack a while back. I have put the radio away fr-or now, but plan to get back to it next week. I gave it a good spray and we'll see if it improved any more. Thank-you

    Restore/Repair and old Radio

    I have a vintage radio that has really nice and rich sound. It had AM. FM SW and another band that I am not sure of. Its make is NordMende FTZ-PRUF-NR. U 106 The radio works, but there is a lot of noise coming from the sliders and buttons on the front. For example, if I increase the volume...

    Circuit Board coding

    Thank-you. Your picture is matches up to what I had described. i guess I was just wondering why A14 on one side of the board, would not equal A14 on the opposite side. Why does it have to be T14? I looked at a few other boards, and I am finding that the coding varies. For example. I have some...
