    Designing a Time Delayed Relay

    John, this is a screen shot of a program I wrote for use with Picaxe ADC input. There's nothing revolutionary about it but it does reduce calculation tedium. After reading your last post it would appear to be applicable for use with blank PIC's too. If you'd like a copy I'll zip it up and post...

    Was, Were, Wasn't and Weren't

    Steve, sure you can. What you typed is saved to disk. You can recall it anytime you want. So you didn't loose any time at all!:p So what would it be????? "If it weren't for Chris' pedantically lame topic I wouldn't have wasted two minutes of my life". Or "If it wasn't for Chris' pedantically...

    Huh?! The Earth must have stopped turning on its axis for this comment to go unnoticed. Chris

    Power amplifier

    Here at Electronics Point "we" usually construe the word "we" in your sentence as meaning class project or homework. We do have a section for that. Welcome to EP, Chris

    Which PIC, LED PWM dimming

    The ULN2xxxx series are all NPN's and all are Common Emitter arrays. They are open collector, current sinking devices. So you can just connect the LED cathodes to them. Your code logic doesn't change because the outputs go low when the inputs go high. ... Through a limiting resistor of course...

    Was, Were, Wasn't and Weren't

    In order of precedence I would have to put Italian at the top of that list. Both my paternal and maternal grandparents were born in Italy. My father would say "Son, there's no language in the world that sounds so sweet. It's like listening to music. It's 'ah singa songa' language"! :) Chris

    Designing a Time Delayed Relay

    You're correct Hop. I wasn't aware that John was that far along (completely loaded PCB) with his project. That fact changes things greatly. Admittedly I would have taken an analog / digital (uC) approach. The only thing I'd have the Pic doing is On and Off delays. I wouldn't have even used an...

    Yes, most if not all U.S. public schools no longer teach Script. My 22 year old grandson can only write script when signing his name! :eek: Chris

    Designing a Time Delayed Relay

    John, I'll admit that I'm very late to the party but this thread is just too long to read all of it to see just how we got here. I did read the first page though. For the life of me the logic at this point is over complicated. I'd want only two things from my dust collector: (1) Turn ON at a...

    Yeah, I caught that too. Funny!! Chris

    Was, Were, Wasn't and Weren't

    This comment will sound odd to a native German or Japanese but I find both languages have something in common.... To my ear they always sound very angry. In fact either would be my choice of languages if I were charged with belching out commands with enough punch to scare the hell out of anyone...

    Was, Were, Wasn't and Weren't

    This topic is truly pointed at members with far to much free time (like me) to ponder what most would consider anal. Especially when you consider that a few decades of smart phone texting has inflicted damage to the English language equivalent to the evolutionary aftermath of an apocalyptic...

    LED Signal Dummy load

    lxlramlxl, thanks for the explanation. It clears things up. Sorry for being so damn persistent. I just wanted to be sure that I understood that you understood what I understood! :p Not to beat this topic to death but I think this is worth pointing out. If you're goal is to determine that the...

    Designing a Time Delayed Relay

    The Picaxe 08M2 is only $1.94. The fact that Picaxe uses a proprietary boot loader embedded in the chip is what makes them so painless to use. All the Picaxe chips are standard PIC's which can be stripped of the boot loader and reprogrammed conventionally as a blank PIC. As far as their stock...

    Designing a Time Delayed Relay

    Chop, I know that Pic+C# or ASM coders consider Picaxe like a bicycle with training wheels but it would have been simple code, up and running a long, long time ago. Leaving you far more time to make chips and dust. ;) Chris

    Designing a Time Delayed Relay

    Hey Chop are you saying you're still turning on the dust collector manually? I thought I was unique when it came to never quite finishing a project. Now I see I have plenty of company! :) Chris

    Reduce Voltage to Zero in Part of a Parallel Circuit

    As Harald stated but you can dim a LED effectively wiring a Pot as a (Rheostat) variable resistor. Chris

    You mean they're still manufactured? Chris

    Pin 7 of 555 timer doesn't discharge

    I've mentioned this before but it's worth repeating. Once upon a time when TTL was the hottest new logic, a company (I think Maxim) manufactured an IC that incorporated a 555 and two decade counters. Using that chip I built timers with delays in HOURS!;) Regardless of that; yes, you're correct...

    Pin 7 of 555 timer doesn't discharge

    Steve, many of the Picaxe family will now operate down to 3V. Even the older chips ran fine on 3 x 1.5V cells. Chris
