Photo booth for the party [Canon camera + Arduino]

JestemInzynieremPL 17409 39

TL;DR

  • A DIY wedding photo booth pairs a Canon camera, a monitor, and an Arduino PRO Mini, but omits a printer to keep the build simple and cheap.
  • The camera feeds video through miniHDMI to the monitor, while Arduino buttons trigger the shutter through optocouplers and a 2.5mm micro-jack, with transistors driving 12V signal lamps.
  • The control system uses 12V DC power, Arduino PRO Mini 5V logic, and parts including 6 x 12V signal lamps, 2 backlit buttons, 2 optocouplers, and 8 NPN transistors.
  • It reportedly ran at over a dozen events for 8-10 hours of uninterrupted work, showing photos on the monitor after each shot.
  • The build was cheaper than renting a booth for 2-3 hours, though some parts of the wooden enclosure could still be improved.

    I wanted the photo booth to be maintenance-free, and when printing photos always have to be nearby (even to add paper). When building a photo booth, the costs also counted a bit, and the legal software to operate the fotobudki to the cheapest does not belong. In general, I was aware of ready-made solutions, but I preferred to do it "my way".

    Exactly, after the event, I am playing pictures of the event organizer and he is already deciding what to do with them.

     
    I know that it's a bit old, but my colleague did not think about putting a printer on photo paper, which prints immediately after taking a photo? Recently, I was at a party, someone normally put a PC with Windows 7 there, some lens (I do not know if it was just a camera or something more advanced), monitor i to potem pojęło. [/ Quote]

    I will add that when I looked for a typical photo booth printer, the cheapest one was probably 2,500.

    Everything ok, except that similar photo booths allow printing. And what was created behind the black curtain will definitely remain there or in the photographer's pocket. With this idea, however, it will remain on the SD memory.

    A great idea, as well as this trivial automation made for it. We have a photo booth at a low cost.

    However, looking at the fact that 2 flashlights behind an umbrella, an amateur SLR, cabling and a monitor for viewing the photo are enough - and the most important trigger, e.g. rf or ir remote control.

    And without a wooden booth we get the same.

    I am impressed with DIY and I will gladly watch the refinement of the project. And as I mentioned before, an RF or IR remote to trigger the trigger. Or a button on the floor that will release the shutter.

    Approaching the button tiring (but also dangerous for the equipment if we find well-knit people). I think that even in this case the concrete base will not save the equipment.

    Inability to print photos is the biggest problem with this photo booth. When it comes to "remaining photos in the pocket of the photographed" it only seems so - every photo booth saves the photos on the card / disk, so there is no hope that the printed photo will be the only copy :-P

    I had the opportunity to check the operation of my photo booth at a few weddings and I will tell you that the kit you describe would not last 2 hours from the first 'One hundred years' for the bride and groom :-P Seriously, drunk people willingly touch everything, move it, push the buttons, stumble, spread gadgets all over the room - I tell you the massacre, everything must be locked :-D

    All photo booths (which I have met so far) work so that you have to press a button on them or touch the screen. I have a plan to add an extra button to my photo booth to trigger photos remotely (RF).

    Well, just something on the floor like a raised tile, where someone touches with your foot and the photo has 5 seconds.

    Remembering the problem of not printing - it's obvious that all other solutions carry costs. E.g. a simple interface on the monitor that would allow you to enter an email. But it's SCI-FI already

    Act Engineer, I will monitor your project.

    Photo booth cool. Such devices should be as intuitive as possible and least demanding in terms of service. In my opinion, the trigger should definitely have a large button and be well attached, e.g. on a column to the ground. The idea with the tile is also interesting. The screen as I noticed displays a real image. It is better if it was a mirror image, it is more natural for people watching themselves in the monitor. As for the lack of a printer, the camera can be connected to a computer where photos are saved in a folder (selected by the user) and the folder is synchronized with the ftp server. In other words, you can have them on your website immediately after taking the picture. This page can be password protected. Now almost everyone has a phone with internet. All you need to do is hang a card with the website address and password. Anyone interested will be able to download such a photo right after taking it, and even upload it to some social protal. It's always an alternative to printing photos. And lower costs.

    I admit that I used to do a lot of things to mirror the image, but I still haven't solved it today

    Then it gets thicker with the control - I suppose the easiest way to buy commercial software then

    If I make another version of the photo booth, this is how it will work :D

    It is worth using the software provided with the camera. Thanks to this, the photos are saved immediately to the computer disk. The image can be inverted by connecting an additional monitor and set to mirror cover in the appropriate multi-monitor program. The downside of this venture is that you have to connect it to your computer.

    And is there any inexpensive (e.g. up to PLN 500) program that automatically sends a photo to the printer when a new photo appears on the camera card?

    I think you can google something. On the first page of the search I found a program for PLN 690 net :-)

FAQ

TL;DR: Built in under a week, this DIY Canon-Arduino photo booth has logged 100 + operating hours and “Arduino gives you much more control” [Elektroda, JestemInzynieremPL, post #17387671] It costs about the same as a 2–3-hour rental [Elektroda, JestemInzynieremPL, post #17385700] Why it matters: shows how low-cost electronics can replace commercial rigs without sacrificing fun or reliability.

Quick Facts

• Supply voltage: 12 V DC rails power lamps, buttons and electronics [Elektroda, 17385700] • Controller: Arduino Pro Mini 5 V with opto-isolated shutter lines [Elektroda, post #17385700] • Camera: Canon 700D, 2.5 mm remote jack, mini-HDMI video out [Elektroda, 17386073] • Enclosure: 18 mm plywood; largest panel 868 × 500 mm [Elektroda, post #17387033] • Runtime record: 8–10 h per event × 12 events ≈ 100 h [Elektroda, 17385700]

What Canon model and connectors are used?

The build uses a Canon 700D DSLR. Video feeds via mini-HDMI, while a 2.5 mm remote-release jack lets Arduino trigger the shutter [Elektroda, JestemInzynieremPL, #17386073; #17385700].

Why not just use the camera’s self-timer?

Arduino lets you set any delay, burst count and LED countdown, giving a richer user experience than a fixed 10-second timer. “I can freely set the time and number of photos taken” [Elektroda, 17387671]

How do you safely interface 5 V Arduino pins with the 3.3 V camera?

Two optocouplers sit between pins D10/D11 and the 2.5 mm jack. They provide up to 1 kV isolation and eliminate ground loops [Elektroda, 17385700]

What lighting gives reliable exposure?

Two softboxes run constantly with 5 500 K continuous bulbs. Manual exposure and manual focus keep results consistent despite venue lights [Elektroda, 17386841]

What are the enclosure dimensions?

Cut from 18 mm plywood: 2 × (868 × 500 mm), 2 × (850 × 500 mm), 4 × (850 × 350 mm), 2 × (500 × 368 mm), 2 × (464 × 100 mm) [Elektroda, 17387033]

How long can the booth run continuously?

It has already worked “over a dozen events” at 8–10 h each, so 100 h+ without overheating or rebooting [Elektroda, 17385700]

Does it print photos?

No printer is installed to keep costs and supervision low. Photos stay on the SD card and are handed to the organiser after the event [Elektroda, 17386841]

How can I mirror the live preview for guests?

Use a small PC or Raspberry Pi with dual-monitor software to flip the HDMI feed horizontally before it reaches the display [rafiti3 suggestion, Elektroda, #18556264].

What are typical failure points?

Edge cases include drunk guests yanking power cables, paper jams in add-on printers, and gadgets scattered around the booth [Elektroda, st4chuu, post #17398788] Secure wiring and limit loose props.

Can I add a wireless or floor-trigger button?

Yes. Replace the current pushbutton with an RF remote receiver or a pressure mat wired to the same Arduino input—no code change required [Elektroda, keychi, post #18512132]

How do I wire the shutter circuit?

  1. Connect Arduino D10 and D11 to LED-side of two optocouplers.
  2. Wire optocoupler transistor side across the camera’s 2.5 mm jack focus and shutter pins.
  3. Upload a sketch that pulls D10 low for focus, then D11 low for 200 ms to fire [Elektroda, 17385700]
