Inductive Sensors for Escape Room puzzles

[@javcis31]

Fantastic video! Coding intimates me to no end, so I appreciate you exploring a strictly-hardware approach to puzzle designing. I'm always surprised with how much you can do with fairly simple circuits!

Recently discovered your videos and binged watched a bunch. Was happy to see your still uploading videos. Thanks for great content.

Awh, thanks! Glad you find them useful. I try to upload at least one video each month - I know there are channels who do much more frequent videos than that, but they typically have an entire production team behind them, and I'm just me :)

Wonderful video and very well explained.. again 😉 We'll be trying these sensors in a candle prop puzzle to put out the candles with a metal candle douter. Thanks for another great idea!

I feel like this is a dumb question, but im 100% new to all of this. What do you use as a power source? I learned the hard way that there is such a thing as too much power. I burned up a mechanism because it was plugged directly into the wall.

Good question actually

[@rjai88]

You mention them being wired into a relay but there isn't one in your wiring diagram. How would this work? And could you use a magnetic release catch rather than a maglock?

Hey I need your help for the video you made on AR app. Please respond

I wonder why the enclosure and huge nuts don't constantly trigger it? Maybe a special material that locks the eddy currents down, maybe it's configured to be blind to the background currents and only trigger when there's a change

[@PlayfulTechnology]

That was exactly what I wondered too! I assume that it's calibrated to account for the metal casing. Either way, I think it's safe to avoid adding any further metal hardware in the vicinity.

[@schmorb]

Does any metal trigger it, or just iron/ steel? Like if we had aluminum ingots and one steel would it ignore the aluminum?

[@PlayfulTechnology]

Yes, it will detect aluminium, but only at a closer detection range than a ferrous metal.
