    solar query

    Hey beautiful people. Just a stupid question. doing a back yard solar grid for some robotics. using el cheapo stuff for some upcoming projects the setup is a simple panel to controller (am 90% sure its pwm but is labelled MPPT but at the cost I highly doubt it.) controller to battery. now for...

    Calculator or kicad addon

    Hey all. Silly question here and i know the maths side (not really but hey). What i am doing is laying out a pcb. I want designate point a to point b. But i want the calculator to determine best route given certain variables like resistance, trace area, mm^2, and preferably use a few different...

    2 mosfets switch

    would this work?

    2 mosfets switch

    its technically 1 load. making a 12volt AC. just making it go faster than 60hz....by about 2,000,000,000 times

    2 mosfets switch

    thanks Bluejets as always. 2 quick questions, are the resistor values dependent on anything? can I use just the left side circuit so when M1 is on M2 is off and vice versa? Am attempting a 12volt application here so if that helps with values.

    2 mosfets switch

    About to ask a silly question I have an application where i need 2 mosfets to turn on and exactly opposite times. If mosfet 1 is on mosfet 2 is off If mosfet 2 is off mosfet 1 is on Anyone got a circuit diagram for it?

    multivibrator circuit

    thanks audio guru. was looking at ic's for this as I want it to go high frequency. still looking at whats best

    multivibrator circuit

    hey bertus, thanks for the info. still trying to check what frequencies this can do. am trying to run an experiment to check different efficiencies on different frequencies with AC. I know it sounds silly but just trying to figure out a few things. adjustable frequency is all i need to drive a...

    multivibrator circuit

    ok so to redesign I need some capacitors in there a choose some transistors to go with it. just trialling something out so variable for first design. even with capacitors what would be the maximum frequency generated? if this is too low for frequency for the job I have to redesign.

    multivibrator circuit

    I see everywhere a multivibrator connected toa transformer for an inverter. question is let say I want to change the frequency from 60 hz to higher or lower do I just chuck in a variable resistor and if so instead of which resistor? also I was thinking of more amps, do I just put more...

    back for a while

    Hello again all, with covid, kidney stones and all the fun that comes with that I got 2 weeks off so visiting old places to keep mind active........ I was gone a while you could have gotten a cleaner in lol

    Adjustable Power Supply Question

    my advice is as a novice too.... what about 2 pots in serial. one with your course and one with your fine adjustments. as long as the overall resistance is kept.... just a thought

    Have a little fun...

    long time no see guys, anyway I am making this project as we speak and the deal is as follows if time past since any switch turns on exceeds lets say 5 seconds then reset switch places after that 5 seconds you HAVE to turn switches on in pattern. the pattern is whatever the LED's are left to...
