    • Yet another simple roller shutter (cover) node

      So after the "success" ;( of my previous design "simple relay actuator" i did another one for roller shutter/cover device Simple cover actuator

      Main goals were:

      1. Simple design (NO SMT) all throe hole
      2. Safe, AC-DC, fuses, creepage etc...
      3. Cheap, no expensive hardware
      4. Easy to build, anyone could do it

      Main Components:

      • Hi-Link AC-DC PSU
      • 2 relay design one for power one for direction
      • Atmega328p-pu
      • nrf24l-01 radio

      IT works very well for me with my Home Assistant controller HA, i am using time to set its position nothing too complicated.

      Again, please comment and ask questions as you wish, thanks for the great feedback this forum is the best.

    • Another simple (No SMT) relay actuator

      Since i dont think humans should solder SMT devices 😜 i made this nice little non SMT board with 3 SSR relays, Hi-Link power supply, atmega328P and separated fuses for PSU and load, in a 5X5 CM board.
      So far its working great, i did not put a temp fuse in the design mainly because i dont see any commercial in wall units using one, so for me i think its safe enough to not use it.
      I would appreciate your comments on it, Thanks.
      Main goals are:

      • No SMT
      • 5X5 CM board
      • Safe for in wall use
      • Simple and cheep

    • RE: Looking for tips on mounting thermal fuses.

      I just wrap it with wet toilet paper, works every time.

    • RE: Another simple (No SMT) relay actuator

      Small update, i connected touch switches to the board instead of mechanical switches.
      where i live we are using gwiss switches and when the board is in the box there is not much room for mechanical switches as they are too deep, so i took some blanks that are used to cover unused switch hols and added touch switch to it, see the pictures below:

    • RE: Another simple (No SMT) relay actuator

      @artipi Sure you can that is the whole point of the D5, D6, D7 connection.

      You just need to take the GND and each of these digital inputs and connect them to the switch (NO high voltage in the switch only GND and digital input), each one of then controls one relay.

    • RE: AC IR code decrypting

      So i ended up implementing it in my own library, still under tests, i will publish it here once i push it to github.

    • RE: Arduino Nano and NRF24L01+PA+LNA

      @Boots33 i could not make the NRF2401+ work with the le33 i moved to lm117 or 662k and it works, just wasn't enough juice...

    • RE: Time condition

      You need to build it using few nodes, something like this:
      0_1464845649905_upload-eb90b026-1915-4d14-89b3-988a706e131b

      Explain:
      the "Clock" node is giving the current hour, the "Constant" nodes are the range of hours, the "Check in Range" node will output a 1 only when the hour is in the range.
      Then you have a AND with the "Door" switch and after you have AND with the "Light" switch.
      Result - light will be on only if time is in range and door is on and light is on.

      This is how i would do it i dont know if there is any easier way other then writing your own custom node, you said you are a .NET programmer so it shouldn't be hard.
      Writing few custom nodes my self i can tell its very straight forward.
