3D Hologram LED Fan, 3D Holographic Video Projector Supports WiFi, Phone App and TF Card, 3D Hologram Video Graphic Advertising Display for Business Exhibition Trade Holiday Show 52 cm

The media could not be loaded. I bought this fan (20.5in model Z7H) to try mount onto an extendable pole to use as a rave totem to display animated GIFs that I can change on the fly from my phone. The device itself is cool and works very well, once you figure it out and learn the limitations.The APP (3D LED FAN for iOS) is in broken English and is not intuitive at all to use. There is no bulk upload feature and no way to organize the hundreds of different animations I wanted to upload. It will play everything that is uploaded in the order it is uploaded, with no way of picking and choosing which images to display.It will read most image file formats and MP4 videos, but it does NOT support GIF playback. It just displays the first frame. For this issue, I made an iOS shortcut that converts a GIF to MP4 and loops it for X number of seconds.PROS:- Surprisingly bright. At 100 brightness it can easily be seen in direct sunlight.- Decent picture quality, considering its a fan. Images are pixelated and have rings up close, but look fine from a few feet away.- Runs at 12V 4A DC, but can run off a portable USB-C power bank with this adapter: USB C to DC 12V Adapter- Has easy access JTAG pins and is easy to root (more details at bottom)CONS:- HIJACKS BLUETOOTH SPEAKERS! Whenever this fan is on, it repeatedly tries to connect to any Bluetooth device in range, and just appears as some generic name. I was unable to play any music through my stereo while it was on as it would connect every 60 seconds and kick my phone off. There is a setting in the app for "Volume Control" with an on/off toggle. Turning this off stops it from doing this, but does NOT save, so this setting will be on again after a reboot...- Creating an account for some cloud service hosted in China is required to remotely manage the device. However, it will make it's own network and can be connected to directly and managed offline if you are within Wi-Fi range.- Management APP is terrible- Impossible to get good video of, as cameras pick up the spinning. Lower refresh rate video works better.TECHNICAL DETAILS:This fan runs on an Allwinner V3s ARM SoC with 32MB of RAM, as well as a proprietary FPGA to control the LED display. The system itself runs Android 4.2.2 with a process named mplayer that controls display of the image and initialization of the system. It hosts a busybox FTP server on a static IP of 192.168.10.123 that the app connects to to upload files. Managing the images is a lot easier with a 3rd party FTP app. However, for it to recognize new images were added/deleted, you must upload something with the official app after you make any changes.I have been unable to locate a full firmware image, but partial updates are available from a Chinese file server found with a quick google search.ADB is disabled out of the box, but I was able to patch the mplayer process and replace the system command to format the SD card to instead start the ADB process.

Chintec POS! Doesn’t work out of box. Also no battery for remote included,!although there is a battery pull tab.

The media could not be loaded. We bought a few months ago. I finally had some time to put this together. The graphics really pop-out when you turn this on. The instructions are not great (not very clear or detailed). Once I figured out how to get graphics on this it blew me away. I tried the cubes for creating and then found I liked straight photos and graphics more than the cube layouts provided.You can adjust the order the graphics appear, the length, and how many times it will play before it advances. It rotates through what is loaded. I put over 100 graphics and pictures on.I made graphics on my computer. Then I uploaded to an iPhone. From there I installed into the app. There is a computer software available but only for a PC not a Mac. Not supporting a Mac is my greatest complaint. Otherwise it is great!The comments from attendees at the conference has been nothing but positives. Lots of stunned and impressed viewers. It drew people to my booth. As a result I have had more opportunities to share our nonprofit story.

Unfortunately device was not syncing to our PC device. To install on an android, You need to download an unsecured app to Android. I purchased this before a show and unfortunately was unable to use it. Would welcome support or help.

This product will drive you crazy at first for 5 legit reasons. First, the directions are terrible. Second, it takes forever to find the app. Third, the app is not at all user friendly and the directions for the app don't exist. Fourth, there is no customer service available. Fifth, you're not going to find a youtube video, or video provided by the company, anywhere that shows you how to setup and use this hologram fan. It took us HOURS to figure out the first steps, and then the next day the app said our password wasn't correct so we had to start all over. That was two days ago and we're still waiting for their Customer Service people to email us back. Still.... even with this product only working at 50% it is still freaking amazing and well worth the money we spent. Hopefully some day we will get the videos to upload and work as well as jpgs. One day the videos work fine. The next day the app won't allow you to upload the exact same videos that use the same mp4 format. Don't ask me why.... customer service never wrote back to give us an answer. Seriously... if you're from China and you' ae selling something in the USA, just pay a US customer to write your instructions for you! And then have them make a simple setup video for you. Or do it in trade. It will save the rest of us hours of frustration and the aggravation of discovering that you actually wrote your instructions from back to front rather than from front to back. But nobody in the US knows because you didn't number the directions. All we know is it's impossible to do what you've instructed. We almost packed this up and sent it back a dozen times we were so upset.

Took a minute to assemble and install the software, but the images are great! I cant wait to download some more and create several of my own.This is a Chinese app and Chinese product. Construction is sound but most of the electronics are exposed on the blades so you have to touch them to assemble it. Definitely secure the fan before you turn it on or it will spin away, fall and then break. The app is NOT listed in Google Play Store (warning), and the entire unit can be easily damaged during transport, assembly, and operation. Mount away from curious people who may inadvertently touch the spinning blades. Great fun!!
