    Help me draw this circuit's diagram

    Hi Marco and thank you. On a cheerer note the always helpful EP family is working hard for you. It would appear that Edd was already dissecting and labeling your circuit as we spoke. ;) Chris

    Help me draw this circuit's diagram

    Dave, it's getting close to Christmas. I get all gushy and fuzzy at this time of the year. I think of all the family and friends that I've lost through the years. Two weeks ago I lost my Mom at 92. She always said "If you don't have something nice to say don't say anything at all". I confess...

    Help me draw this circuit's diagram

    Hey guys, lets not be elitists and badger mosfet66. I think we can all agree that we are by far the friendliest electronics forum in the world. Let's keep it that way. M66 please do as advised and give a go at reverse engineering the PCB. Then post what you drew. We can then attempt to correct...

    Variable capacitor

    Hey Collen, whatever floats your boat! There's nothing wrong with prototyping on a wood board. When I was a young sprout that was invariably my protoboard of choice. If you research historic photos and drawings of electronics inventions you will find exquisitely hand made Mahogany platforms...

    Help me draw this circuit's diagram

    In the event that you don't remember where you got it take a look through all of these LM324 PWM Motor Control schematics. Odds are you'll find yours or many very similar designs. Chris

    Variable capacitor

    It could very well be a variable capacitor or two fixed caps with a null control to adjust for stray capacitance. Either way it's definitely a lab standard. It's certainly not something I'd build a regen receiver around. Chris

    Variable capacitor

    Florida law dictates that if there's no bike lane then you should be in the lane for your direction of travel. Positioning yourself along the right curb with a (Right Lane Must Turn Right) puts you in a more dangerous position than being out in traffic. The vehicles turning right will run you...

    Power consumption of vibratory pump when pumping against closed valve

    It's not confusing at all. Read here for detailed explanation... https://www.electronicspoint.com/threads/what-is-a-high-low-level-trigger.276582/#post-1673942 :p Chris

    What is a 'High/Low Level Trigger'?

    Paul, I read your manual. Isn't reading Chinese Pigeon English such fun!? :D Fortunately it was much easier to decipher than many I've read. BTW: Welcome to EP! Paul, if you catch the bug (as you say) you will undoubtedly be posting often. In that case it will be unavoidable for you not to...

    Variable capacitor

    Not really. General Radio was never known for consumer electronics. They were known world wide for top of the line (expensive) electronics instrumentation. Your link points to a capacitor lab standard. Chris

    OK, I see your better at decryption of Colin's posts than I am but I still don't get his reference to a Variometer. Did you click the link I provided that describes a Variometer? :confused: Maybe he had a brain fart and meant Varicap. BTW: His website beats the hell out of his posts! Chris

    Colin, do away with what? As for VARIOMETER ...please elaborate. Chris

    20 Watt LED Dimmer Circuit diagram

    Getting info from the OP has been like pulling a T bone steak out of the mouth of a hungry Pit Bull but I think we do know that he understands a series - parallel array must be used. As for the Chinese clone issue,... I wouldn't know. In the far past I've used many 555's @ 15V with no issues. Chris

    Multi location thermostat

    Where I live if it gets too cold in the house we just turn off the AC. If that doesn't work we open a window. :) Chris

    OK, how does Goofy work for ya? :p Chris

    Multi location thermostat

    Multiple thermostats on a system that's not independently controlling the temperature of each location makes little sense. Chris

    20 Watt LED Dimmer Circuit diagram

    Colin, that's a perfect PCB for him. Now he doesn't have to answer any questions and he can fill in the values himself!:p Chris

    Possible help programming a Picaxe 08?

    Read page 52 & 53 of PDF1 (Getting Started) manual. Chris

    20 Watt LED Dimmer Circuit diagram

    Repeating the same requests is becoming tiresome to read. You seem to have an aversion to answering our questions. BTW, your 25KΩ pot may be too low for the persistence of your eyes to perceive a change in LED brilliance. Chris
