RE: Safe In-Wall AC to DC Transformers??
Hi guys (and gals?) new member here, and probably an absolute novice compared to most of you; however, I have been following this thread for quite some time. I recently acquired the components listed out by @petewill (thank you for the inspiration to try the project), and I have constructed the circuit in tune to the schematic also generously provided by @petewill. The only difference in my set up is that I have gone with a WeMos D1 mini instead of the arduino/radio combo solely due to having one laying around. The WeMos to relay connection works (as in flicks on/off the LED on the relay) in tune with the automation software I am using when the WeMos is being powered by micro USB. However, when attempting to power the circuit via a 120V outlet, I seem to keep blowing the 250V 300mA Slow Blow Fuse. In short, the LED on the WeMos briefly emits light, and then shuts off. When troubleshooting the circuit with a multimeter, I find that no current is flowing through the Slow Blow Fuse (therefore blown). I was wondering if anyone might have some ideas as to why this is happening despite the fuse being rated with the proper current and voltage ratings. I assume that there is a short occurring somewhere in the circuit; however, due to my novice knowledge, I have no idea why. I would greatly appreciate any and all pointers/criticism!
