    Circuit Soldering question

    Sorry. I didn't realize there were different kinds, other than the printed ones. The one I am using is the same as the pic you posted.

    Circuit Soldering question

    Today I began experimenting with taking my ideas off the breadboard and putting them on a regular circuit board. I am working with non printed boards, so my question is this. To connect components to one another underneath the board, how do you do that? Is it by running solder somehow? Is it...

    Parts needed?

    Thanks Harald. I am so new to electronics, that I can't even discern when people are beign sarcastic, and when they are being serious. lol. I didn't see a solution on that thread, other than hauling around an amp and a mic...lol

    Parts needed?

    I have a friend whose son has this really bad habit of running his finger horizontally across his face just above the lip, where a moustache would sit. It is so bad, that area is always red raw. Are there a couple of components that can work together, one as a wrist band and other clipped to...

    Stupid question about Resistors

    When using a resistor, does it matter if the which direction you out it in. Does the band that shows the threshold, have to face a certain way?

    A ground / negative connection question

    Hi Audioguru and thanks. i was not necessarily going to use this circuit. I am only trying to understand whether the GND designations should be connected to a negative lead or the ground terminal. So, are you saying that the connections of the 0.1uF capacitor at pin 4 and pin 8 of the NE555 and...

    A ground / negative connection question

    I hope I am posting this question in the right forum. Can anyone look at the circuit diagram shown at 1:11 in the video referenced. I need to know the following: When building this circuit, when it shows the three connections at the bottom of the diagram as going to GND (ground), does that...

    Powering LED strip

    Thanks for the ideas. No, they are not double taps. I am using the cheapest guitar I have (and I have 16 of them).

    Powering LED strip

    Hi Martin. That's an idea and certainly affordable. i was able to find the same unit in my home country on Amazon. My only concern would be the board., It would be a little more difficult to conceal the board, and I am not sure if it would survive, using the guitar for gigging and on stage...

    Powering LED strip

    Just to provide a better sense for this project, here is a picture of the guitar I am working with and the Led strip sitting roughly where it will go. I am thinking that maybe run black or white wires (whatever blends in better with the color of the guitar and its pickups), down the side of the...

    Powering LED strip

    Harald: I can confirm what you said about the LED strip. Its magic happens with the controller. But on its own, it simply has a positive terminal and three other terminals. If I connect the positive and alternate between having the negative on one of the three others, the color changes. Other...

    Powering LED strip

    Hi folks. Thank-you for the observations. I did get the LED strip to blink, but it had to be at a higher voltage. If you are saying that the transistor is not a good choice for this, and I should try a CMOS 4093 as an oscillator, I will. At this point, I am making progress in the sense that it...

    Powering LED strip

    Ok...I think I am close to what i want to achieve. I actually have a circuit that uses a 1 K resistor, a BC 547 transistor and a 47uF capacitor using a red LED. I actually got it blinking, however I am sure I have the correct capacitor called for in the circuit. The one I am using, says it is 47...

    A ground / negative connection question

    This is helping. Thank-you. What and why is my question . The why is because I am trying not to get confused between the negative lead and what it does, and ground. Having read the replies, let me see if this is true: 1. Ground can be used as a reference point to measure voltage that is...

    A ground / negative connection question

    Hi folks: I am getting reacquainted with electronics. I have always had an interest in it, but after taking electronics in high school, I allowed it to fade into the background. I am now 58 years old and trying to rediscover it. Having the internet and access to relative;ly cheap components...
