Turntable (platform) for product photography

Question

Arduino

Hello!

There is a task: you need to shoot (photo) a large number of shoes in order to mold pseudo-3d from the pictures ( example ). For such shooting, you need a turntable (table).

Of the ready-made solutions for product photography, I found solution 1 , solution 2 , solution 3 , etc., but they are either too expensive (from 50 thousand rubles) or too simple (they spin, without the ability to rotate by a certain degree). As a result, I figured with my comrades that such a platform could be made by ourselves on Arduino, and it would cost no more than 5-6 thousand rubles. (Arduino components and electronics for 2-4 thousand rubles approximately turned out + expenses for PVC and small things).

Ideally, the system should work like this: put shoes in the middle of the platform, after a couple of seconds the platform starts moving with a stop every N degrees (or N seconds), at the moment of stopping the camera takes a picture. The platform made a 360-degree turn and the system stopped.

We are thinking of initiating the shooting process a) by closing the contacts on the remote control of the camera (imitation of pressing a button; you will have to unplug the remote), b) by physically pressing the same button (servo drive), c) arduino and the camera will be connected to the computer, the signal to the camera will be transmitted programmatically (I have not yet studied this issue in detail, but it is theoretically possible, after all).

Components: Arduino board, weight sensor, stepper (or conventional) motor, motor driver board, servo. Well, every little thing.

There was no experience in assembling anything on Arduino, so I ask for help! Have we taken into account the components? Are there pitfalls? Maybe someone has already done this and will suggest ready-made solutions (circuit, components).

Thanks in advance! :)

Answer 2

We go to a flea market, find a record player, tear off the head and everything that sticks out.
The engine there is simple, usually 220v, I would personally make control to it on any relay or (if the relay strains with sound) on a triac / thyristors.
To control the turn, if you don’t need super-accuracy, then in time, but if you need it more precisely, then we put a mark on the motor shaft with an ordinary black marker (or better, on a pulley on the motor shaft) and remove the revolutions with an optocoupler for reflection, then we catch it on the counter. There is no optocoupler - we are looking for an old ball mouse, we pick out a wheel with holes and a translucent optocoupler from it, then it’s clear.
What will control - the tenth question, at least an arduino, at least to attach to a PC - it doesn’t matter.

Answer 4

If the camera is a Canon SLR, then everything can be done on one relay, google on canon remote schematic.

Answer 5

Stepper motors are just for this, well, or servos with a rotation angle of 360 degrees. However, stepper motors will be better here, servos can "tremble."

You can assemble it yourself or buy it as a set.
