    analogue memory system

    Am I right when I say, theres not one internet forum for electronics that handles experimental design. So no-one is to do experimental design on electronics forums. That was my mistake. Seems like a damn shame to me, It could be fun... You better watch out for my ALU, cause it has a...

    analogue memory system

    The voltage. But u could also put in the mathematics, half the capacitance, because that is also true, if you say that a capacitor shrinks as it fills up, and becomes a smaller and smaller capacitor as it gets charged up. Thats why its non-linear, because it only gives out what breath its got...

    analogue memory system

    How about alternating between positive and negative, is that better language? What if the capacitor is half charged? The ALU isn't in the diagram, its only the analogue register. So high frequency is better said "more frequent" rather than fast. Thankyou for the distinction. I always...

    analogue memory system

    I dont mind the bad precision or the lossy state, having a 1 line bus is worth it, especially if you have physical restrictions. Im going to be hooking it up to be an analogue physics engine, like the old differential analyzer simulations back in the olden days I imagine to myself, only...

    analogue memory system

    Thats ok, I know that im a bit of an alien when it comes to doing technology, I definitely didnt get experience with years in HAM radio thats for sure, not that I even know what it is exactly. I have designs for wallpaper lcd screens, but I couldn't fix one that you probably could. (Like a...

    analogue memory system

    Hopefully this picture is neat enough to be understood. You catch the value in an exiting capacitor each time, and u get to keep reusing the "signal level". The idea is, you set the capacitor to a setting, and then it ping pongs with an ac signal, and it can keep repeating the same amount...

    Polarity Switching

    Does it have 3 wires? maybe the center is the ground, but of course you would have tried that right?

    Battery question

    Thanks for the info, sorry if my drawings are so hopeless, I've got a ghost in my mouse which makes them messier than they should be. But I definitely learnt something. I learn something new every day.

    Battery question

    If you have the batteries backward to each other, it looks like I did the drawing wrong, and its not 9v up the sides, when its inverted I think the batteries are actually going in series with each other, because im getting a louder response with them both connected. It actually conducts...

    Battery question

    I mean no attraction as in the battery + of one battery isnt attracted to the - of the other battery, like we were saying. Theres 9v on all lines except the centre, where the battery power seems to be passing through itself, subtracting - and cancelling out. Phase cancellation - if you will.

    Battery question

    I tried out an experiment and I found that the 2 batteries pass through each other with a dull response in the centre where they are overlapping.

    Battery question

    The amazing thing here is that if you have 2 batteries in a circuit, Is I think they can actually conduct on top of each other and return only to their own negatives each. Isolation, be it capacitor, battery or transformer, I think they all exhibit a similar property. But is there a...

    Battery question

    Thanx dave9, but I meant making a circuit from 1 pole of one, to 1 pole of the other, and that doesnt work. But yes indeed, you can put them in series, as long as they are a full circuit including them both.

    Battery question

    I found this, thanx. https://physics.stackexchange.com/questions/75052/why-does-connecting-a-batterys-positive-terminal-to-the-negative-terminal-of-an#:~:text=The%20positive%20side%20of%20a,the%20potential%20difference%20reaches%20zero.

    Battery question

    Say you have 2 batteries. Can u conduct from the + of one battery to the - of the other? If you cant, and they have to be from the same battery, why not?

    I cant measure voltage on 100 picofarad capacitors on multimeter

    I'm sorry if I dont seem respectful or grateful, I actually am, maybe I should thank you all now for helping me out. This forum has been invaluable to me already, even tho I've only been here a shortwhile. Thanks alot!

    I cant measure voltage on 100 picofarad capacitors on multimeter

    What about gigohm resistors - ive seen them on the internet.

    Need help with DC Dimming seven seg displays.

    Yeh I know, when the light hits the resistor it shorts the power away from the base of the transistor. :)
