Has anyone used the 2.4GHz or 433MHz boards for locating objects in the model cars, drones and, especially, model rockets? 

I'd be interested in knowing your results and whether the 2.4GHz or 433MHz board is "best" - read "able to better locate the object"

You can do this with a pi zero, but for a smaller option we do have a Tiny Video Player Kit:
Or the TinyTV kit that comes with a 3D print TV enclosure and remote:

This also comes with a smaller display, however, but I am not sure how strict of a requirement that is for your project. More details help on the project would help me help you!

Let me know,

I am new to the SBC world and have a small project that I am trying to configure. All I need is for the SBC to display a video (10-20sec) on a 3.5inch screen. What would be the smallest and fastest SBC that can accomplish this? I have a Raspberry Pi Zero and was wondering if there is anything smaller and thinner than that?

Thank you

Does anyone know of a good mDNS library that will work with the TinyZero?

I've written a sketch for bi-directional UDP communication between my iPhone and  my TinyZero with WiFi Shield. It works well, but the TinyZero has a default host name of "winc-42-f2". Catchy huh? I'd like to set a custom host name, but I can't find a mDNS library that will work. I've tried MDNS_Generic, but when I follow its guidelines, the resulting IP Address is

I'm also looking forward to your experiences with this device, as some non-technical types have asked me how to upload videos to this unit.

1. Any file size or video length should work, the larger and longer the video, the longer the conversion will take. The longest we have tested is a 2.5 hour movie.
2. Those formats should work. mp4 is the most commonly used format
There could be some corruption from the main video. I would recommend trying different videos to see if you can rule out that it's a specific video causing problems.

Let me know if you see the same behavior on multiple videos.

General Discussion / TSV Video conversion issues

I have a question regarding converting video files to tsv to play on my tiny screen.
1. Are there many video requirements for a file to be converted such as bit rate, type file, file size or video length?
2. What type of file will the TSV Converter actually convert? mp4, mov, avi etc.
As you can see by my attachment after conversion by the TSC converter when the file plays on tiny it's like it's multiplied several times over, it's jittery and looks terrible. I have attempted to create a file in .mov, mpg, avi , mp4 formats and nothing seems to work and I always get the same result.
This is frustrating, to say the least. I would appreciate any advice, assistance you can give.

Hello there!

I have some great news. If you purchased the kit in the last year, it shipped with firmware that includes a settings menu. This tutorial shows how you can navigate to the settings menu, and what settings are available:

The settings include "Loop" and "Autoplay" modes that should work perfectly for your project.  You can also elect to use a different remote with the IR settings if that could be of use!

If you have an older kit, you can upload the newest firmware using this tutorial:

I hope that helps! Let me know if you have any other questions.

Would love to see the model you end up building when you're finished! The hardest part of selling cool hardware is that we almost never get to see what happens with it  :'(
General Discussion / TinyScreen + setup

Good Day,
Just purchased the TinyScreen + package, pre-loaded with video, plug, and Play - Nice. I am building a model, it has a display screen, plan to install a tiny screen in the model so when powered it will loop play the .TSV file on the display panel in the model. I noticed when I power up the TinyScreen it requires interaction, press the button to select a video, then select the button to play video. QUESTION: Can button selection be bypassed and the single video file placed on the micro memory card begin playing and remain playing (loop) until I power off the display? As it stands now the Tiny Screen requires interaction (press buttons) for any TSC file to play and once the file completes, you have to select afile or press play again.

Thanks in advance for your help.
