Hey everyone, I have unfortunately not much knowledge about projectors but I’m looking for a portable battery powered projector to do some outdoor projector mappings but also use for movie nights in the forest. I would do this in the Austrian alps so therefore it’s very dark and I think even projectors that aren’t that bright would work. Ideally it wouldn’t cost over 250€. If someone has any recommendations for this I would highly appreciate it!!

Hi,

I am completely new to using a Raspberry Pi. I borrowed one for an exhibition, it is a 4 Model B (2018). The artwork is a simple video projection that runs on loop. My problem is that it requires a bit of mapping, it's not a simple standard rectangle format. I found the ofxPIMapper software, but it specifies that it is not compatible with a Raspberry Pi 4. I was also looking at MapMap, but I'm using a Mac and the DMG installer isn't available (or maybe I'm mistaken?)

Is there a way to make one of these two softwares work, or are there other softwares out there that could do the job?

Thank you for your help!

Hi everyone,

I’d really appreciate some advice on my project. I’m a beginner in this field.

I have a restaurant where I’m planning to launch this project by the end of October.

Project description

I want to create an immersive theater-style experience where projections are displayed on both the walls and the table. An animated story/cartoon will be playing, and everything will be synchronized with ventilation, scent diffusers, etc.

The scent diffusers are custom-made, so I can connect them to virtually any control system if needed.

At the moment, I have two projectors, so I’m planning to start with those:

• one projector for the table;
• one projector for the wall.

So, where should I start?

Which software would you recommend for projection mapping and synchronization?

I’ve just tried MadMapper, but I’d like to learn about other software options as well.

Any advice on the best workflow or setup would be greatly appreciated.

Im completely new to this and in need of some guidance. Any advice is really appreciated.

Environment and Projection Surface:

Small dark room and projected onto either one or multiple 50x50x50cm white cubes.

The following links are examples of what I intend to try.

Projection onto the side and front of a kitchen cabinet.

Projection onto a white cube and using an iPhone that has the mapping software

Projection onto multiple white cubes

May I ask,

1. Are those doable with only one projector, or do I need at least two?

2. If only one projector is needed, what should I take note of in terms of how I should map the images or video loops so that it won't look wonky or off?

3. What should I take note of when buying a projector? From my research, 1500 - 3000 lumens is ideal. But what is best? Should I just go for the 3000 lumens?

I assume for my purposes, I should be using an ultra short throw. But apparently, "UST models can struggle with highly complex 3D tracking sensors due to edge distortion." May I ask for some tips on how to address this?

4. Any recommendations for a low-end projector that suits my purpose? Budget is below $500 usd. Yaber T1 Pro?

5. What mapping software should I use? Im looking for something free at the moment.

Perhaps Lazy Lighting, 4 Mapper, Map Club, MapMap, VPT 8? Any recommendations on those you've used before? Anything specific i should take note of?

I know lightsource from DLP projector is not a point so it is difficult to create colliminated light source. But is there is any idea, please suggest me!
