    3-Axis Stepper Controller

    You won't be able to supply 12 volts to the stepper in this configuration. Just connect to the board. In a configuration where you use 12 volts for the stepper, you usually use a different stepper.  Aren't your steppers 5 volt ones? I thought this was the case. In a setup where you would use...

    PSU WITH LCD VOLTMETER--TROUBLE!!

    Stath, I am not clear why you are using an adjustable regulator, then you have an additional adjustment pot after the regulator. This can cause some loading on the other circuit. Also, this depends a lot on the schematic of the voltmeter. If you must have an isolated ground, you can use a higher...

    motor driver L298 help

    Where in Rod's post did he say he was specifically refering to a DC motor with brushes and a commutator, or a brushless motor with an electronic commutator? Seems you have hijacked another thread to discuss your own subject.... In fact, it seems that you have scared Rod away. He hasn't posted...

    PSU WITH LCD VOLTMETER--TROUBLE!!

    With a quick look, C1 should be a much larger value. Also, the voltmeter has it's own setup. It must only use a samll voltage form the larger supply. For example, the voltmeter will have input resistors that scale down the voltage so that it is really only looking at approximately 200 mA. So if...

    motor driver L298 help

    The guy in the tutorial had a hell of a time making this work. You go ahead and make it any way you want, audioguru. Could you please explain the code in the link you have cited as the reason you disagree with me? oops. Sorry. I forgot. You do not know how to program a micro. But going back to...

    Creating/making Music ICs

    Tkjas, you posted in the wrong area. You should have asked this question in the microcontroller area where programmers would have given you an answer. Here is a link that will help: http://www.embedded.com/story/OEG20010221S0034 Best of luck! MP

    PSU WITH LCD VOLTMETER--TROUBLE!!

    Without looking at your diagram, I can only guess. But it sounds like you just need a split supply. You do not have to use the same common for two circuits. There are many designs where the common for one section of a circuit is floating at a different potential than the common of the other...

    amplify..

    In looking at your schematic, it seems that you are powering and also grounding your motors through the relays. Perhaps I misunderstood which lines were which. However, if this is the case, I would advise that you use a permanent ground or permanent voltage connection and only use the relay for...

    A Sticky Topic About "Getting started in electronics"?

    Just my 2 cents on the subject. Since a lot of this is based on field of study and individual taste, there would be so many posts that it would at some point not be very helpful. ...and of course, then you would have those members who want to argue about what is best, and that someone else's...

    Oh, yes it does.....I think you have once again become argumentive on a device you have never used....Your statements would be true if you were feeding the signal directly to a motor. I think both of you have missed this detail. We are discussing the input of the L298. Not a motor. In our...

    PCB photofabrication

    Faizanbrohi: We are discussing how to get good results with photo etch. Not glossy paper. There is another thread about using your method. You should post in that thread. By the way, I totally disagree with your comment. There are many tight designs where glossy paper just pushes out crap. Works...

    motor driver L298 help

    No, You don't even need to change the width of the pulse to change speed. No, I am not talking about anything that has to do with "Pulse WIDTH Modulation", including any of the projects. I am talking about basic TTL clock signals that have been around for years. Simple. Change the clock speed...
