A LARP Safe

A safe for Arsene Lupin!

How to build a LARP safe that can be lockpick using a stethoscope?

Description of the effect

The safe of a bank. The correct code, and the owner will open … For Lupin, a stethoscope will do! This safe really opens with the sound when you lockpick it!

Nice idea!

It is simple, affordable and fun! Indeed, it will surprise a player when discover another one with a stethoscope on the ears and on the vault. It’s clearly a process of lockpicking!

How it work

Serrure codée rotative

We will use the rotary lock available on Cré’à’Vapeur – Le Shop. It will allow us to control the opening code, of course, but the opening of the safe itself and the lockpicking part.

 

 

Ingredients

  • Rotary Lock, then! Ready made or DIY. (€ 29.90 kit).
  • An Electric Latch. Wich will manage the opening of the safe itself (€ 19.90).
  • 12V adapter. For a version plugged in, otherwise a small 12V battery will do. (6 €)
  • The wood furniture that will serve as safe. With a vintage look for western, or modern. A second hand one around € 10… Here, for the purposes of the tutorial, I made a box with six wooden boards and two hinges…

In the end, you can get it for around € 50 only!

Recipe

Placing the closure system

Watch your little piece of furniture … Think about the way in which you will place your electric lock. Here, with my furniture, I place it on the door, inside, and put a emtal stop on the left inner wall.

Marking on paper

We will use a simple little trick, we’ll mark the latch screw holes on a sheet of paper, then, simply refer them on the door.


Drill and fasten the electric latch

Drill the correct diameter (here, with the latch – version B, it is drill by 3 mm), then 4 screws and screwed the latch. Be careful what you screws are not too long!!

Screw the stop

For the metal stop, I used a small angle that I had deep in my toolbox. Using a marker, I marked the position of the latch and I screwed the stop at the right place. Measure for not doing anything stupid!


Position the lock

I have make an opening in front of the door to allow the rotating part of the lock going through the door, and I’ve screwed with the nut that’s provided with the lock. It only remains to put a button that will go in the style of a safe. Mine was found in a provider of electronic components.

Wiring

It’s not complicated. I passed the AC Adapter – 12V through a small hole in the back of the safe. I cut the plug 10 cm from the end. I bare it all, and I reconnected red  with red and black with black. I attach the yellow latch wire on black. It remains only to screw the adapter into the red terminal at the center of the lock’s relay, and the red latch on the left terminal of the same lock’s relay. Look on the picture to help you, o). Remember to glue wires using a hot glue gun (not like the photo, it’s just a demo support ;)


Set up the lock

Use the booklet that came with the lock to program the code of your choice and activate “lockpicking by sound” and it’s ready! Your safe is running!

Suggestions have

Ultimately, you are now the proud owner of a special LARP safe! Now you just have to paint it (metal color). For those who would not like AC adapter, use a small 12V battery!
