    I will need to study that circuit diagram before I can fully understand it. What a neat idea !

    Thanks to you i've repaired my washing mashine phantom play touches. After drying front panel from inside it works like a charm. Moisture was the problem!

    YES! These touch things are a bugger, thank you for giving me a solution and an option of remote operation. I watch a lot of electionic channels, your's is by far the most inspiring and original. I wish you every success and happiness my dude 🤘

    Excellent video dude! and such a simple circuit :) my current project is leading me towards the use of capacitive touch as the input device and that circuit looks very robust, could be stuck to almost anything and doesn't break the bank to build, marvellous! much love from over in England, 8-Bit.

    Capacitive sensing is a proud specialty of cypress psoc microcontrollers. They self tune, can be endlessly configured, and there’s beautiful software to interface with it. Psoc devices are the most underrated microcontrollers on the planet for medium complexity design

    This is exactly what ive been looking for now for over four years. Currently, i use a mechanical setup to actate a Capacitive button on a mobile air con unit. It is a servo, and arduino nano with a temp/hmidity sensor. Once it hist a certain level, it actualtes the servo and does the same again to switch off when the air is cooled. It is being interfered with by AC i think, works fine for a bit then constantly switches on and off.
    Im hoping this will solve my issues!!!!

    This is really useful. I hate capacitive buttons so much. Capacitave touch screens are awesome but a touch "button pad" should never replace mechanical switches. Combine this with a $5 esp32 micro and esphome firmware to automate just about anything! Awesome.

    Thanks. A clear conductive film would be ideal electrode material to preserve the visual switch indication.

      @@leosbagoftricks3732 there are a number of suppliers online, however I believe a small amount of powered graphite rubbed onto clear adhesive tape may also work.

      Making a hole in the copper tape before applying, with a paper hole punch, would work too

      @@jfpsimon good point, the metal spring describes a circle under the front surface - I expect a circular track of copper having the same diameter would still have about the same capacitive effect as Leo’s copper pad.

    Interesting! I've used Reed relays in the past for the same purpose.
    Tip for a new video: creating a variabel frequency sine wave circuit with only analog parts.

    Hello, I set up the system according to the plans provided by you, thank you! Im using it on a Boohenka dehumidifier (the one with the 1200ml tank). For switching, im wanting to use a raspberry pi zero 2 w GPIO (so 3.3V instead of 5V). However, i cannot get the system to run reliably. I was playing with the on and off switching times on the raspberry, but only managed to let the dehumidifier switch on once (not reproducible). Could the voltage be the reason, or is there something else I could adjust? Im now upping the voltage with a optocoupler (AZDelivery KY-019) as a first step.

    What happened to your electronis class?

  • @kpnconsulting8739
    @kpnconsulting8739 7 месяцев назад

    Fun little circuit. Presumably the cap is to give a slower transition between levels. Also helps debounce the switch. But what's the deal with the diodes?

    • @leosbagoftricks3732
      @leosbagoftricks3732  7 месяцев назад

      The capacitor bypasses the voltage divider node, making it a lower impedance at the high frequencies. The diodes? did you watch the video?

  • @NiksSofa
    @NiksSofa 7 месяцев назад +2

    Interesting. that should work with mobile phones or non resistive touch screens too, right?

    • @leosbagoftricks3732
      @leosbagoftricks3732  7 месяцев назад

      not necessarily, this is intended for non-matrix, single electrode sensor buttons.

  • @JTordur
    @JTordur 5 месяцев назад

    Very good
    Here is what I learned, using two diodes like you mentioned, make a very simple high impedance, but simple to control node in a circuit.
    And as always, the way you make custom hand made boards is very inspiring!
