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.

I really like the product, but we've struggled with the instructions, setup and with poor customer support. Its a quality product, but is useless if you can't program and operate it.Sincerely;Customer needing helpClarenceO

Installation and assembly will take you sometime and the instructions are slightly limited. However customer service is quick and responsive to any questions you may have. Some of the pros is an impressive display, video does not do it justice. The image is smooth and easily visible with none of the black lines seen in the videos of the device. Connecting to the app is also pretty easy, simply down 3D magic from the AppStore. Then connect your phones WiFi to the hotspot of the fan which starts with CS. The password is on a white label at the base of the fan motor. There are two things needed for it to work after those steps. 1. You need to turn off your data so that the only connection your phone has is to the CS hotspot. Turn on the fan, do not click any of the buttons on the base. The fan should glow once powered on. On the app click Setup> Upgrade Package > Download Newest Package > Select model X65. Download will show successful. Click the same button which now shows Install Package and BOOM! Your setup is done.Some cons was that I had to figure out a lot of these things through trial and error. The fan blades are extremely delicate and are held to the motor by very small screws similar to the ones found in eyeglasses so losing them is a real possibility. My remote wasn’t functioning but that could be because I haven’t connected something properly. Last but not least there is no audio. You have the option to purchase a sound box directly from the company and they are more than willing to help you out. I absolutely love this fan and I am excited to have it apart of my arsenal of technology.

Shows promise. Looks great on the wall. Been able to transfer two photos. Unclear if it can handle more than two at a time. It does have instructions but the print is a little too small. Would be nice if they were more clear.

The media could not be loaded. I first purchased one of the cheap knockoffs - half the size, a quarter the price. but it just did not work. hardware seemed flimsy and the software was in chinese and did not work. Even if it had worked - that device (like many others) requires the video file to be converted to a .bin formatTHIS unit works great. files need no conversion (mp4 etc work directly). remote control works well. the PC and mobile control programs work very well. Easy to add/delete/reorder videos over wifi (these units will be mounted 20 feet up on a pole at a trade show). You can start and stop, set brightness etc. Image is very bright and is visible from a long distance.I plan to purchase three more.Edit: I just ordered three more units. That says it all.FYI - All the demo videos the seller has on their site are of fully 3D objects spinning and moving. I am using this for a trade show display and wanted to display 3D looking text that is moving, changing. I checked aorund and finally decided to just create it in powerpoint (it can export to MP4 HD). After all, what I want is multiple "slides" each with animated 3D text, plus some images and videos. That worked great! I would post a video, but due to "rolling shutter" it is very difficult to video a spinning object.edit - two years later. These are still working great and with them up on that pole (there are two back to back at 16 feet and two back to back at 13 feet, rotated 90deg) you can see them from hundreds of feet away. People come walking up with their mouth hanging open and ask "How the hell does that work?"
