Escape Room Design Tutorial - "Blow the Bloody Doors Off!"

[@wakafeek]

Very cool! I get nervous around circuitry but you made it very clear on how everything works. Thanks!

[@mfx1]

You can also get "monitored" door magnets which will confirm the door has been properly shut again when the game is reset. You can also make very robust switches with a magnet attached to the spring loaded plunger that actives either a reed switch or even better a hall effect sensor.

[@PlayfulTechnology]

You're absolutely correct, and I considered mentioning Hall/Reed sensors to detect movement of the plunger (which is a technique I've used also), but wasn't sure if that might lead to confusion with the other Reed switches mentioned.

[@lennylein]

Your videos are always a great source of inspiration - Thank you so much!

[@markanthonynilo9198]

I always enjoy your video Sir. Keep them coming, I always admire them...Bery Entertaining. Old or new upload is always cool. May I ask a question, is it possible to make a seven segment disay that will upload to a computet monitor using Node Red? Do Node Red have a template for that, Or I'll have to build or design it my self. I have lots of questions. Thank You Sir.

An important feature of mag locks (as opposed to padlocks) which I don't think you mentioned is the fact that they fail safe. I've been in a room that the exit door was locked physically and I wasn't happy that in an emergency, the door wouldn't open on its own. That situation has now been changed.

amazing work

[@stevenw3017]

My son wanted me to tell you that he loves your work :) To be fair, I do as well. See you in Puzzle People :)

[@PlayfulTechnology]

Awh, please say thankyou to your son! (and, if he ever makes anything Arduino-y or puzzle-y inspired by any of my videos, I'd *love* to see it!)

[@WakWak208]

Great video, thank you very much! I have a question about the 12 volt power supply. On the wiring diagram you can see that there are 2 power supplies (12 volt) but in the part about the components I only see one. Is it still necessary to buy a second one? I have no knowledge of electrical networks, sorry.

[@FFBpictures]

I love this! But, wouldn't it be easier to use RFID? Like say you have 2 sticks of dynamite and a plunger in which you have an rfid chip in each. Then after placing the dynamite on the object (whether it be a door or something), you put the plunger down in the hole and then with RFID do it?

[@johnirvine3346]

I am not a fan of your safety method for the mag lock. What I do is create a latching circuit for the relay that releases the mag lock so once the relay has been activated and releases the mag lock the relay stays in that position even if the charges are removed. Then I have a hidden or locked away reset button to reactivate the game. Latching circuits are very simple to wire.

[@PNWZombieWatch]

Awesome stuff. BTW, It's ferrous surfaces. :)

[@ImperialLightandMagic]

Was waiting for the two magic words "Robust" and "Durable" :)

[@mfx1]

It's quite a skill making what's often called "Museum grade" mechanics/electronics, never underestimate the destructive power of the average punter and particularly small children.

[@TheUnofficialMaker]

You could make it where when the door is blown open, it cuts off the power to the mag lock until you manually reset it for the next game.

[@ericjohnson8180]

How do you avoid the audio looping? The DFplayer loops if you hold ADKey1 which your relay would do if the player holds the plunger for too long.

[@PlayfulTechnology]

Lots of options, but the most trivial is simply to append several minutes of silence onto the end of the explosion sound effect.

[@mvl8209]

Do you know a webshop that sells cheap maglocks? (and it's not necessary that they're strong) I'd like to make an escape room at home and use a mag lock but all I find are too expensive for 1 or 2 times use. I love your videos!

[@Pepsiaddicto]

you can get them on Amazon for around $20 for weaker ones.

[@mvl8209]

@@Pepsiaddicto Oh really? Thanks! I'll take a look :)

[@mark_just_mark]

Does the lack of an Arduino, in this scenario, affect the way this type of puzzle can be controlled by some sort of ‘games master’ software?

[@PlayfulTechnology]

Yes, absolutely. And, while some people favour the "keep it simple" approach and don't introduce microprocessors where they're not strictly necessary (which I can appreciate), the counter-argument is that, if I'd done this using an Arduino, it would have presented far more opportunities for, e.g. monitoring/resetting/triggering remotely from escape room software, adding additional game logic, or more features (let's say you also want to trigger some lighting or a smoke effect via DMX when the explosion goes off)

[@duncanx99]

Am I missing something? It would seem that, with normally open reed switches, the maglock would be DEenergised when the 'exolosive charges' aren't in place over the reeds, which kind of defeats the object. Maybe I'm misunderstanding...

[@Dawktour]

Watch the video again... The RELAY is set for normally closed (maglock powered on).

[@PlayfulTechnology]

The Reed switches are normally open, which means the *relay* is not energised. That means that maglock, which is connected to the "normally closed" terminal, *is* energised.

[@duncanx99]

@@PlayfulTechnology Duhh, sorry - I'd forgotten the relay was changeover...

[@tkturbo_jsps]

Once de-energized, just leave it de-energized. How you miss that? Re-energizing is wasteful overall.
