"Safe" opening for a specific hand movement

The safe responding to certain passes of hands was made by the Master from India. The whole trick is that the safe does not need keys that you can lose, or they can be stolen from you, and you won’t be able to open the safe without knowing what manipulations to do. To make a safe, he needed the following

Materials and tools:
- Plexiglass 4 mm;
-Cardboard;
- Servo drive 13 kg / cm (4.8 V), 15 kg / cm (6.0 V) 40 mm x 19 mm x 43 mm;
-Arduino uno;
-Ultrasonic sensor -2 pcs;
-Photoresistor;
- Resistor 10 kOhm;
-Wire;
-Laser cutter;
-Glue:
-A computer;
-Switch;
-Screwdriver;
-Soldering iron;
-Nippers;




Step one: model
Before making a safe out of plastic, the master made his model out of cardboard.



Step Two: Laser Cutting
In the graphics program, he designs the details necessary for the safe.

Sends for cutting. There should be eighteen details in total.




The link allows you to download files for the CNC.

Step Three: Build
Begins the assembly of the safe. First, the master collects "dry" to check the alignment of parts. In the final assembly, glue is applied to the mating surfaces.
Assembles the body of the safe. The case will be installed electronics and box.






Assembles an inner box.



Sets jumpers.




Fourth step: electrical part
Sets the servo, sensors, switch.









Connects according to the scheme.



Sets the box. Screws the cover to the servo lever.




Step Five: Firmware

When everything is assembled, you need to flash Arduino. The code contains the following parameters for opening the lid:
- the left hand is at a distance of 2 to 10 cm from the left ultrasonic sensor, and the right hand is from 8 to 16 centimeters from the right sensor
- then the left hand moves at a distance of 8 to 16 cm from the left sensor, and the right hand should close the photoresistor
- further the right hand moves a distance of 2 to 10 cm from the right sensor, and the left hand closes the photoresistor
- and finally, both hands are at a distance of 5 to 13 cm from each sensor, respectively
- the hands are removed, the green LED lights up, and the safe cover opens.




The code can be downloaded from the link below.

All is ready. The safe is assembled, the electronics are working. Power is supplied via a USB cable from a computer.



The process of assembling the safe can be seen in the video.

Get you a link, also safe
Specifications electronic piggy banks Safe
Size 20 x 14 x 14 cm;
Plastic material;
Power 3 AAA batteries
.
As a journalist, you should understand that the key word here is “piggy bank” and not look for links to sites
Original and unusual gifts! © 2012-2016
, and look at the meaning of the word in serious sources, however, I have already cited them, but you continue to persist in your wrongness, trying to make fools of others!

How you got me. What does not suit you in the name? I have 423 articles,

1. As a journalist, you simply must know the language and call a spade a spade, dictionaries to help you!
2. Over 2.5 years, 423 articles, an enviable creative capacity for work, and how many of them are yours? Or do we scuffle without delving, if only to cut down the grandmother?
3.
are you trying to teach me
Learning is always useful, it is a pity that you do not understand this!
4. Verily, every person can make mistakes, but not everyone is given the opportunity to recognize and acknowledge their mistakes!

As deemed necessary, and called
Well, again, back to the topic of responsibility for your words? And after that you call yourself a journalist?

So what? As deemed necessary, and called. It was necessary to write as the author of CUBEX - SAFE SENSOR ARDUINO?

Well, do not want to call a safe, call a box, a box.
In this particular case, the name "safe" you gave!

About the red button. In the comments on the homemade master explains that it will be involved in the future when installing the battery.

Open the safe - you have to sweat
-I assure you, you are mistaken. In evidence, I can give a photo of hacked safes. Tomorrow I’ll take a picture, on Monday I’ll post it, well, or tomorrow if I have time.

You can hrenak a metal safe.
First up! smile For the gifted, I repeat:
Safe (from the English safe, literally - safe, reliable) - a strong metal box or a cabinet for storing documents and material values.

Big red button on the back or bottom (did not figure out the coordination) boxes why?
I took it on my chest with friends, I must add - to the safe behind the stash, and the passes with my hands are no longer ..., well, to hell with them, with the passes, we have a secret button! smile

Open the safe - you have to sweat. Even apply welding or grinder.
And this is a box for girl secrets.
The mouse ran, waved its tail, the box fell and crashed. : haha:
The same irremovable code is also a fun topic.
90% of the description is the manufacture of a plastic box, and only at the end the essence is a steering machine from models and a headscarf with firmware. And oh god, a description of a fixed code to open. : haha:: haha:

SAFE Male gender Fireproof cabinet, drawer or special room in banking institutions for storing valuables.

Safe (from the English safe, literally - safe, reliable) - a strong metal box or a cabinet for storing documents and material values.

and to open the safe without knowing what manipulations need to be made will not work
I propose one of the possible, trouble-free manipulations - to lift and hrenanut on the floor! smile
