I woke up this morning to another finished product! I created a 4 inch air inlet to air box adapter. I hacked together pieces of previous designs to achieve the final item pictured. One side will connect to a 4 in fan duct. The square side [of the adapter] will connect to an air filtration box. This is technically a prototype as this was only printed with 40% infill.
Homelab update : Home Assistant Motion sensor hardwire!
I hard wired two Samsung Smartthings motion sensors to avoid having to constantly purchase and swap out old CR2 batteries. So far it works like a charm. 3v @ 1.0A(-+5%). Battery to adapter conversion. That's a hack. Right?
Video coming soon. Covid-delayed.... my son has Covid. 😞
Version 2.0, without the barrel connector, looks much cleaner and is a far better option for most. 3d printing a case is an option for the novice user.
Approximately 2-3 times a year I am contracted to do a product 'housing' design.
Video is complete. Editing to remove passwords & most pii. V2.0 hardwired motion sensor is acting strangely. Then again.. i'm 88.97% sure it was reporting oddly prior to being modified.
I'm currently working on getting home assistant working at 100% now that the PLEX server is up and running. Once the motion sensor is installed I can use it for 'stepping up' current automation configurations.
Amazon has still not arrived with the 3v adapter after 2x delays.
I opted to purchase from alt seller. Hopefuly it will get there today.
