    How to generate negative voltage from PIC

    There are numerous different models of the PIC MCU and many of them are pretty affordable.  Have you tried using the pic to just perform a switching function, and then using an inductor, caps and a 555 to produce the levels you are trying to obtain?  The PIC should be able to monitor and control...

    High Voltage low amperage

    I was planning to run the project off a battery.  Are flybacks an effective choice when using a battery?

    High Voltage low amperage

    What is the best way to generate a significant voltage, say 10,000 volts; but at a very low amperage, say 0.02?  I've looked at a few different basic possibilities, but mostly they take up too much real estate.  So perhaps this is more of a question of what is the most space efficient way to do...

    Linear response

    Perhaps he is seeking to remove noise from what he feels is an overly elaborate circuit by using a microprocessor which, theoretically would be able to smooth things out by responding more quickly.  Much like generators in cars were replaced by alternators in 120 degree phase to smooth out the...

    Power Plugs

    Thanks DerFly!  This company you've suggested has some really interesting products.  I'll have to look into them in the future for other parts of my projects.

    Power Plugs

    I'm actually researching a replacement for this design that may involve glow plugs from RC aircraft.  I think it will be lower maintenance and easier function if the numbers add up.

    Power Supply for capacitor bank

    Another thought.  How much affect will the inductor have on nearby ICs and semiconductors?  Should I do anything to isolate or shield it?  And if the affects are significant enough on certain components, what is the most effective way to rearrange them?

    Power Supply for capacitor bank

    Unless it were a topology issue.  I'll work on redrafting it and see how it works out.

    Power Supply for capacitor bank

    Well, the diagram you posted has two LM393's much like the one I am working from.  Mine labels the pins used on each and uses differing symbols, suggesting different purpose.  U1, in my diagram has pins 8 & 4 connected; these are designated as Vcc & gnd respectively.  While U1.1...

    ColecoVision Internal Power Supply

    I have an old emulator archived with around 80 games.  My folks still have the original systems, but they need various repairs.  The one even had an Atari expansion you could plug into the side to play Atari games.

    Those were great consoles.  We had two growing up.  Where on earth would you find one these days?

    Power Supply for capacitor bank

    Been reading through data sheets and IC layouts/circuit diagrams.  Would pins 1-4 be one half and pins 5-8 be the available portion that you mentioned substituting for the 555? Went back and added the diagram I was referencing.  Thought it might help.

    Common ground, seems a sensible solution.

    Power Supply for capacitor bank

    Thank you for the additional explaination, it is helping.  The part I asked about being "open" are the highlighted areas of this image.  I don't recognize this notation or symbol.  I've made certain to keep it in the more legible PNG format that you recommended.  Overall, I am endevouring to...

    I just can't understand why its so hard to find a simple, round 2 prong outlet and mated plug.

    Power Supply for capacitor bank

    Perhaps you could explain a little of how this works?  Also, what do all those open ends connect to in your diagram?

    can anyone help me to make a conveyor a simple one with 3 diff. sensors???

    How complicated this is depends on your requirements.  How large a conveyor?  What types of things do you need to sense?
