I have just been doing some mods to my 900 x 600 mm Ruida 6445G controlled machine including auto stop start on the ventilation system.
Sometimes though I want the ventilator to continue to run after the end of the burn and that’s possible when I change back to manual however I wanted it automated.
Enter the microcontroller
I put together a small device with display and selectable extended run periods between 5 seconds and ten minutes before it turns itself off .
I will be ordering printed circuit boards to mount everything onto and 3D printing a housing but I wondered , before I order, if this might be interesting for other users.
If so, please just drop me a note in the next 5/7 days so I can order boards if needed.
I know everyone will be wondering about cost, so am I
For that reason I will be trying a much cheaper microcontroller than the current ESP32 that I’m using.
Really I just want to know if it’s interesting to people.
LOL, a microprocessor and display and a run of boards just to turn a fan on and off.
You’re as bad as I am.
Edit: After i reread my post I hope it didn’t come off as derogatory in any way. It wasn’t meant to be, I think it’s a great project and I’m curious to see the finished result. It just seems like overkill for such a simple task, in that way that I have done so many times in the past.
I totally understand the relationship between overkill and fun.
It seems to be a fact of life that coming up with a nice enclosure almost always takes longer than the electronics it houses. Nice job on the acrylic enclosure!
I was looking for a commercial timed relay to do the delay and was coming up with units in the 35 / 45 Euro range and that’s why I went to the 7 Euro home built.
THEN…
AliExpress and for 8 USD about 8 Euro there’s the commercial unit…so why go through the making of housings etc…
Here’s a previous thread setting out everything, thanks team
