The converter tool uses ffmpeg, the commands it uses are below.
They are basically the same between models, just changing the resolution and increasing the quality on TinyTV 2.

It would be more work to automate the normalize option, but this is the command it uses:

Code Select Expand

ffmpeg.exe -i "in.mp4" -vn -ac 1 -af aresample=10000,aresample=async=1000,asetnsamples=n=210:p=0,aresample=osf=u8,volumedetect -f null /dev/null
You would run this on the file and parse the max_volume result. A result of max_volume: -1.9 dB means you would use volume=1.8dB in the commands above instead of volume=0.0dB

Will the associated battery be drained or will it truly charge?

Last post by stanleyadkins - October 02, 2025, 10:06:10 AM

Yes, it is possible to interface the 433 MHz Long Range Radio TinyShield with the EFM8UB1-SLSTK2000A via the SPI interface, as long as the voltage levels are compatible and the SPI configuration matches on both ends (clock polarity, phase, etc.). You'll need to configure the EFM8UB1 as an SPI master and ensure proper wiring (MISO, MOSI, SCK, and CS lines). For development, the preferred IDE would be Silicon Labs' Simplicity Studio, which supports the EFM8 series and allows you to write Embedded C code with full access to device configuration tools, code examples, and debugger support. Make sure to check the TinyShield's documentation for any specific commands or initialization sequences required for communication.

TinyDuino Processors & TinyShields / Re: Has anyone worked with Tin...

Last post by michealmoses - October 01, 2025, 11:33:33 PM

I've never used the Tinyduino, but I can say the TinyZero board has worked very well in my experience! The TinyZero has proved very stable and works well with the Arduino IDE (even version 2 of the IDE). From experience, there are a few subtle differences between a TinyZero and an MKR Zero, but these differences should be negligible for a prototype.

I don't know a lot about Bluetooth shields, but TinyCircuits does offer a shield compatibility sheet eggy car to evaluate which TinyCircuits shields can be combined together. This may prove helpful for your prototype!

I hope it helps!

I'm not too familiar with Bluetooth shields myself, but TinyCircuits provides a shield compatibility sheet that's worth checking out — it could be really helpful when figuring out which shields work together for your build.
Hope that helps!

Maybe I'm just not seeing it, but I cannot seem to find a search option for this forum?

I don't want to be the bad etiquette guy who posts question that have already been asked and answered lol.

A TV2 kit would be awesome.  While the prebuilt is very cool, it would be nice to have the option to build your own versions or perhaps 3D print custom cases.

Last post by TomKatt - September 30, 2025, 07:10:35 AM

Recently bought the TV2 and love it !!!  Any chance this version will be available as a kit?  Or where a screen display can be purchased?  I've been Googling around and it seems like the majority of small displays are lower resolution...

Thanks for a great product!  I'm going to start playing with the software now ;-)

Try resetting your device, sometimes it is a software conflict. Or do you have any good solutions?

TinyTV & Tiny Video Player / Re: Tiny TV 2 - AVI Format and...

Last post by parsons3 - September 23, 2025, 10:56:30 AM

When I first bought the TinyTV 2, I assumed any AVI file would play, so I was just as surprised as you when most of my videos didn't work. I also try to keep my Mac secure by downloading only from the App Store, so I completely understand your hesitation. I experimented with a couple of well-reviewed converters from the store, but none of them produced the correct format. In the end, the only reliable method I found was using the official TinyTV Video Converter. It's not ideal, but it seems like the most straightforward solution right now.
