These are expensive in low quantities, making it difficult for us to think of adding them to our standard line of lipos as a tiny business without having a specific reason or market opportunity.

Hello,

Not all of the default example videos have audio. I recommend changing the channel/video by pressing the upper left button to cycle through. You should hear a static sound effect when changing channels.

Upload - uploading files from your computer to Thumby. The opening of a windows explorer is intentional in this case.

Save As - save open files in the code editor to Thumby.

These are the intended uses of these buttons.

Hello,

Buttons in the code editor will have some helpful hover text, and we also have a longer form description of all the different panels/widgets in the Code Editor. Here's the section that mentions the Upload button in the Filesystem: https://thumby.us/Code-Editor/Widget-panels/#filesystem

Let me know if you have any other questions!

That's so cool!

Do you have any other product ideas or ways that TinyCircuits hardware could be used in an RC Car? It would be fun to work on a project tutorial that shows how our stuff can be useful with this community!

Thanks so much already for all your details and information, we're very new to it and have lots to learn it looks like!

In the link above for the tutorial that demonstrates how to view hidden files, there is an option to use a shortcut instead of a terminal: https://mackeeper.com/blog/show-hidden-mac-files/

There are a few other options as well. Hope that helps!

Hi there,

The processor is the TinyScreen+ board, get started with the software and boards package you need here: https://learn.tinycircuits.com/Processors/TinyScreen%2B_Setup_Tutorial/

Then you can follow this tutorial to download and then upload the TinyTV code to the TinyScreen+ and start editing it:  https://learn.tinycircuits.com/Kits/Tiny-Video-Program/

You can also check out some of the built in settings here that require no programming: https://learn.tinycircuits.com/Kits/TinyTV-Tutorial/

Hi there,

The best resource I could find is the datasheet for the SI4432 chip - starting in section 3.5 on page 25 the frequency control is detailed. You can download the datasheet here: https://github.com/TinyCircuits/TinyCircuits-TinyShield-433MHz_Radio_SI4432-ASD2162/raw/master/res/Si4430-31-32_Datasheet.pdf

RH_RF22.h is the header file used by the transmitter example code, you can take a closer look into the RadioHead library on their github, or by downloading it:
https://github.com/PaulStoffregen/RadioHead/blob/master/RH_RF22.h
https://github.com/PaulStoffregen/RadioHead/blob/master/RH_RF22.cpp

That should point you in the right direction for configurations!

Hello John,

Depending on how your accelerometer functions, you may be able to detect a pulse on one of its pins and use that to trigger the interrupt.

Here's the documentation on the attachInterrupt function: https://www.arduino.cc/reference/en/language/functions/external-interrupts/attachinterrupt/
And some helpful hints specific to using an accelerometer in this Arduino forum post: https://forum.arduino.cc/t/configuring-interrupt-on-accelerometer-lis331hh/174168/3

Hello Andrew,

Thanks for your patience in us getting back to you!

- Can assume the OLED resolution will always be the same.
- We don't see the OLED module changing to use an external vcc.

This is great! Thank you for sharing! I've posted this resource in the TinyTV section of our Discord server for those that use that resource primarily. If you want to check it out you can join using this link: https://discord.gg/zkvxTUtHMe

Hi there,

We've seen this issue one other time in the years we've offered the TV and the same converter, so this issue is difficult to narrow down. The syncing issue must be happening during conversion from the app, but given that this isn't a consistent issue we'd like to recommend using a different computer if you are able. If a different computer can convert the videos without a syncing issue we might be able to resolve the underlying issue. Can you send one of your mp4 and converted tsv videos so that I can convert it here to see if I can replicate the issues on my windows 10 desktop?

How out of sync is the audio with the video? Does it get worse over time?

Cheers,
Réna

Glad to hear you were able to find solutions! Thanks for updating the thread with your findings.

Réna

Thanks so much for your interest and ideas! It would be cool to have some tutorials or products tailored to RC Cars.

I love the video! Thank you for sharing it.

What board would we need to connect to a standard RC Receiver? What software do RC Cars normally use? We're not experts on this, so any details or info you share would be helpful!

Cheers,
Réna
