      AnalogKid replied to the thread ac current limiting.
      No, you don't. Charging lithium batteries is more complex, and *much* more dangerous, than charging other battery chemistries. Also...

      AnalogKid replied to the thread Simple LED Analog Clock Idea.
      Only if it is guaranteed that only one LED will be on at any given time. Also, this technique puts a reverse voltage across the off...

      AnalogKid replied to the thread Simple LED Analog Clock Idea.
      A minor nit. I would go with only one orientation for all resistors. Consider one or two vertical columns of shift registers down the...

      AnalogKid replied to the thread Why can't I breadboard this oscillator?.
      In that context - which we know *nothing* about - what is it you are trying to achieve? (both practically and electronically) ak

      AnalogKid replied to the thread Curved lines in PCB design.
      Nigel - it looks to me like everything can be done with a single-sided board; no need for any copper on the component side. Did your...

      AnalogKid replied to the thread Photo interrupter Connections.
      Without knowing the voltages / circuits connected to pins 7, 6, and 2, it's kinda hard to say. ak

      AnalogKid replied to the thread how do we find the period?.
      Because that is the length of one cycle. If a waveform or chart has a repeating pattern, and each pattern is the same, then the period...

      AnalogKid replied to the thread how do we find the period?.
      If the waveform is a constant frequency, then the period is the inverse of that frequency. The period is the time between two identical...

      AnalogKid replied to the thread Op Amp not working and overheat.
      The negative end of the 1 V DC input must be grounded. Note that when the circuit is working, it will not be able to operate at a gain...

      AnalogKid replied to the thread help please.
      So, back to the original question - what are the power supply output voltages and currents you want? ak
    • AnalogKid
      AnalogKid replied to the thread help please.
      What do you mean by "CD"?
    • AnalogKid
      AnalogKid replied to the thread help please.
      The video you linked has links to other construction pages. The first one has schematics for a power supply that makes +/-20 V...
    • AnalogKid
      AnalogKid replied to the thread help please.
      Both what? You need to be much more specific about what you want, because we do not know your application / system / whatever. Input...
    • AnalogKid
      AnalogKid replied to the thread help please.
      Without a more detailed review, the schematic looks fine at this point for +/-12 V outputs. The outputs can not be adjusted up to 15 V...

      AnalogKid replied to the thread LED circuit for 1/6 scale diorama.
      The problem with #32 and other posts is that Light and Ridiculous should stay on continuously once illuminated. One way to do this is...
