Great video!! Thanks so much for the final tip (Multiple magnets w different orientations)!! Great less expensive solution than RFID for the more simple end of the object identification problem!!
Neither a reed switch or Hall sensor *needs* the Arduino - you can use the output from either to switch a transistor which activates/deactivates power to a maglock directly, say. The advantage of having the Arduino is that it allows for calibration and easy customisation of the puzzle behaviour logic through code (imagine if you wanted players to hold the magnet in place for 3 seconds before activating), as well as allowing remote override should the sensor fail, or integation with a room controller that can monitor/reset puzzle state etc.
Loving your content. I think you have that backwards between SS49E and A1324 sensivity. Respectively, 1.4 mv/Gauss and 5.0mv/Gauss,... Given a supply voltage of 200mv (For simplicity's sake), the SS49E would have 142 (200/1.4) segments of measurement and A1324 would have 40 (200/5). Usually the more segments, the higher the sensitivity, or did I miss something?
Is there a standard for the 'screw on' magnets, in terms of which face is the North pole? How do spherical magnets work - is one pole 'buried in the centre of the sphere'?
Great question. AFAIK, there's no real "standard" for the screw-on magnets, and it's not something I've ever seen stated on a product description either, so you'll probably just have to test empirically on a particular batch (and hope that, at the very least, all the magnets from the same batch are the same!). Spherical magnets are divided into two hemispheres - much like the Earth itself - with a North pole and a South pole at opposite ends.
@@PlayfulTechnology Thanks I have some spherical magnets on order (to drop through an aluminium tube - to amaze a five year old Peruvian with 'techie magic'. We'll work up to the explanation when she's a bit older.
You can either wire them in series (so no current flows unless all are closed), or hook them up to multiple pins of an Arduino, and program it to need all activated.
Hey I recently discovered your channel and I instantly LOVED your content. You do a great job of making your extremely cool ideas 😊!! Could you just make your videos a little shorter with more sort of abstracted, less technical info? Thanks a lot and ALL THE BEST

your channel is a gold mine
your channel is a hidden gem. wow
You are awesome and my inspiration for building escape room puzzles!

I love you channel.
`My choicd would be the Reed switch as it does not need a arduino but can be an easy switch. Nice to see a prop build again.

Hi, how we can to contact to your regarding affiliation with us?
Can we get a link to that 3D printed mount?
Thank you friend
Que sensor es el que usas el último?
شكرا استاذ
على الرحب و السعة!
how would you add in more sensors (so all sensors had to be activated to release maglock?)
You can either wire them in series (so no current flows unless all are closed), or hook them up to multiple pins of an Arduino, and program it to need all activated.
Can you create a code that once it reads 4 specific colors, maglock releases. If you make it with sounds even better. Please
Google "arduino color sensor" Or you can have make it cheaper using a neopixel (not a strip) and photoresistor
