    Help me draw this circuit's diagram

    Edd, I had a drag stick duct taped to the blacktop end of the 10' thin wall. It was quite a bit shorter and very pointy by the time I got home! :p Chris

    Working with high voltage pulses

    Duke, your post got me thinking of a totally different approach. Both you and Glen McGillan`s PDF addressed the negative effects of electric fences on telephone lines. As I see it an electric fence is damn near the same as Marconi's Spark Transmitter but lacking the spark. This started me...

    9-phase generator without a microcontroller (it works, but phases aren't where I expected)

    Steve, that's a nice link. It's well structured. Along with the graphics I actually was able to understand it. At the moment my head feels like someone embedded steel shrapnel in my head and then shoved me in an MRI! Chris

    9-phase generator without a microcontroller (it works, but phases aren't where I expected)

    Not to be picky but it's improper or rather a misnomer to refer to the 74HC14 as a Gate. On the other hand it's New Years morning here. So it might be acceptable at the moment. :D Chris

    9-phase generator without a microcontroller (it works, but phases aren't where I expected)

    You mean it's all stored in your head right now or is it scribbled on multiple bar napkins? The attachment is my design. It was developed after many years of design in environments less than conducive for intellectual thought. I call it the Lazy Z.:D Chris

    You did a very good job of providing a detailed description of your project but you know that we speak schematic here. ;) Chris

    Working with high voltage pulses

    OK, so now that Glen McGillan's thesis has given us a clear picture of typical electric fence topology and electrical requirements I scooted over to Ebay to see what the Chinese are marketing. I've made a habit of doing this because the Chinese export explosion has totally changed the advantages...

    Working with high voltage pulses

    I think this is a first for me. I read the whole entire thesis from start to finish! I save a lot of information that I start reading but never finish. Not this one though. While reading this I thought to myself this is exceptionally detailed thesis, especially for a device not targeted at home...

    Working with high voltage pulses

    Yeowza! What a great find. I'm still reading it while I type. I just wanted to be the first to say good job! Chris

    Help with decreasing current

    One does not feed a 7812 regulator with 12V. They need overhead. Personally I don't think you need to do anything more than maybe including some spike protection but if you insist on reducing the battery voltage a bit you can use 1 or 2 1N4002 or higher Diodes in series. Chris

    Newb looking for help: Connecting phone to old speakers [pictures included]

    Yeah, that looks like only 18 gauge wire in the photo. The ends look waaay to frayed and messy too! Chris

    Working with high voltage pulses

    Could you please provide us with link to the product page? Chris

    Newb looking for help: Connecting phone to old speakers [pictures included]

    I doubt that the wire is gold. More likely copper that can and will oxidize. I don't like the way this image looks at all. You need to clean the dust out of the speaker connectors. I would also cut off the bare wire and re-strip a fresh end. Try not to cut any strands. Chris

    Help me draw this circuit's diagram

    If we're taking votes I feel more than sure it's a ceramic cap too. BTW, why does that board look less than factory made? Chris

    Linker files

    I just want to let you guys know that I've enjoyed reading this thread. At this time my PIC/ASM expertise is abysmal. Playing with MikroBasic and exporting my ASM or HEX files into my Tina Spice drove me nuts with error messages, so I haven't attempted messing with any of it in months. My...

    replicating gun recoil

    Yes, if you throw a line-less anchor it should work. I can think of equally heavy but cheaper objects to throw though. :) Come to think of it I had a confrontation with a pedestrian today. I think he's just about the right weight! :D Chris

    replicating gun recoil

    Hop, the anchor analogy had me in stitches. I've had boats all my life and must admit I never tried that. I guess because over the years I've found that my boats were more sea worthy without gaping holes in the hull! :p As far as throwing the anchor past the stern and into the water is...

    Rotary Switch Source

    Yup, rotary encoders are cool but sometimes a simple switch will do. Happy New Year Harald, Chris

    replicating gun recoil

    I'll say again. Blowback has nothing to do with recoil. Even a slingshot has recoil. In fact if you fire a speargun out of water you'd best keep the butt end clear of your face! Ask me how do I know? :D Chris
