    Voltage Amplifier Stage (VAS) design

    Chris you crack me up, I am enjoying the apple growers (cider) so yes lets look at it later. Nice comment though he made about no one on here can help him! I can think of half a dozen people, me and you included that could piss this. Adam

    Running servo motors with PIC and L293D H-bridge

    If you want to control this as a motor then you use the + and - for control and not the PWM wire. Adam

    Voltage Amplifier Stage (VAS) design

    What about the power amplifier output stage, do you need that explained also? I find it very strange that you have the input and output stage but not the bit in the middle. Adam

    My Introduction Thread

    Hi Andrew, welcome to EP. I made this really cool thing once called a fridge :) Only joking. Basic electronics components are very cheap, you can pickup bags of components on the internet for not much money. You will however from time to time need something more specialised which can be more...

    Turning an LED Off when voltage is applied

    How many LEDs? You could use transistors to do this. Adam

    Yeah I agree otherwise others might think ak stands for absolute Knob. :D

    Just learning the ropes

    For me it seems like John and Martin were right. Dave what were you referring to regards the 500K, it's just you didn't come back on that? Adam

    i give up.. lm317 + 2n2222

    "Tone-of-voice disclaimer: No way am I attacking you or your circuit; I think this is an excellent discussion" I am glad you said that ak, This was beginning to go pair shaped. It's so difficult to communicate via text alone, people can come across so rude and arrogant, but they are not...

    What is the basic software for designing Schematic and PCB's

    Have a look here. I personally use Dip Trace. https://www.electronicspoint.com/resources/list-of-eda-packages.39/ Thanks Adam

    Adjustable Schmitt Trigger Circuit Help

    LOL, I don't know why people are reluctant to click the like button, they come across grumpy and stuck-up to me. You are never too old or experienced to learn, I know I have learned lots on here. I think personally it shows you are friendly also, and gives encouragement to the poster that well...

    Adjustable Schmitt Trigger Circuit Help

    Yes I agree, It is very frustrating when the OP just seems to disappear. There maybe a reason for it, but it wouldn't hurt to be polite and just say, thanks guys won't be able to look at this for a while. In answering threads in detail as you do, does give help to others. But unfortuanatly most...

    Sensing circuit for line following robot

    Care to tell us what it was then?

    Hi everyone

    I am sure it's because they think we have the brain of Dobby the house elf from Harry Potter :) Dobby has a sock! :eek:

    It's because they didn't have highwaymen back in the day which is why they drive on the other side of the road. Adam

    Unregulated power supplies

    The problem I have had with battery chargers is when they are on load. If you speak to the charger manufactures they may tell you that a battery should be charged off load. I tend to agree. The problem with too larger load whilst charging a battery prevents the charger from going into...

    i give up.. lm317 + 2n2222

    Yep good one Chris. Another option there, removing the need for a large expensive resistor. However the OP did ask for a circuit that replaced the resistor with a BJT. Why I am not sure? Thanks Adam

    i give up.. lm317 + 2n2222

    We have had issues with Alerts, this is something Ian is going to look at for me. The circuit is not that obvious when you first look at it, but once you know how it works then the theory is self explanatory. You could have a switch box with different values of resistor to set the max current...
