    Convert uneven pulses

    Hey guys, I'm curious about something. Since the Rotary Phone system was never intended to dial at the speeds a uC achieves did they or the PBX incorporate any debouncing? Chris

    looking for feedback on feasability of this idea...

    Hop, unless I misread his post the Thermistor isn't related to the generation of heat portion of his project. As I read it he wants to replace the Photocell action of an off the shelf LED night light with Thermistor functionality. Thus the LED's turn on when it senses a temp below a set value...

    Ohm resistance controller

    A clarification please. Do I understand correctly that this will be an automobile cruise control? Chris

    Hi Herschel, You're going to absolutely love playing and learning UC's within the Picaxe environment. The Free Picaxe Editor 6 is fun to use, intuitive and very powerful. Moreover, it links to the "Help" PDF files, that include all Picaxe commands with included code snippet examples. The 3rd...

    You'll find all the Picaxe to PIC equivalents on page 16 of the Getting Started (PDF1) manual. Chris

    PIC 12F675 PULSE COUNTING

    This doesn't address a false reverse state but I couldn't resist posting this because it exemplifies why I love Picaxe so much. This code snippet brings Pin C.2 low if it counts less than 8 pulses per second. Sensing a false reverse state would be equally simple. Chris High C.2 Freq: Count...

    Clean square waves using a 555 timer?

    I don't think I can drink enough to make that look like Texas. :D Chris

    Total beginner... so I don't know if what I want to do is easy or hard!

    If you receive an email alert that I made a new post ignore it. I posted a schematic that I drew many years ago but saw a serious error. I didn't want something that seriously wrong floating around the net. Chris

    I've accepted that translation to languages other than Chinese is not a Chinese priority but Logos too!!!!o_O Chris

    I wasn't sure if your Iceland mains followed U.S. standards or not. In the U.S. a SPST switch is acceptable for use with 120V loads because Neutral is used making only one leg hot. On the other hand 240V loads don't utilize the Neutral leg. Because of this both legs are Hot with respect to Earth...

    Clean square waves using a 555 timer?

    Hello Ted and welcome to EP. It's been a long thread which makes it easy to miss the replies that previously addressed all of your points. So, unless I overlooked something, it's doubtful that anyone is going to dispute them;....except for one. I agree with Dork's commentary of why using the...

    Yes, resurrecting this topic is going to be very difficult, especially for the old farts among us. I'm glad I'm not one of them! I thought you already had a main power switch. If not, your correct in your assumption that power won't be removed from the Run winding when your FWD/REV switch is in...

    The HANTEK 5102P oscilloscope

    It's absolutely astounding how the Chinese seem to be able to supply the world with just about any product imaginable and do it with irresistible prices. It would also seem that coherent instructions in other languages is not something they've mastered yet, nor something that they loose sleep...

    Detect harmonics with arduino

    I wouldn't think that Mains THD would be a factor to loose sleep over. Is this project going to be measuring Mains or the output of a DC to AC Inverter. ********************************************************************************** Hey Adam, I see your new avatar.

    I think your let Pins[X] command needs to be preceded by the Let Dirs[X] command; or did I miss it? Also, when copying code from the Picaxe editor and pasting it on EP please enclose the code within Code Tags. This way it's formatted properly and is considerably more readable. Chris

    Clean square waves using a 555 timer?

    Since we're going back in time with the early posting of waveforms it may also be worth mentioning that the scope's cal output test (though the breadboard) should be considered totally inconclusive. After all, the Cal output is not injecting any surge current on the Vcc rail as the 555 does at...

    Clean square waves using a 555 timer?

    Dork, IMHO your scope is plenty good enough to analyze the overshoot issue of this topic. Your decoupling results should be pinned somewhere in the forum! :cool: Talk about the importance of proper decoupling ... WOW! :eek: Chris

    I've been using Spice for quite some time now but I'll readily admit to not being an expert when reading spice code. This link has been a great aid in improving my understanding of it and the various flavors. The most common of which would be PSPICE. http://www.ecircuitcenter.com/index.htm As...
