Simple gadget?

[Aggie32]

I am trying to make a gadget that will be able to receive code wirelessly and make the code into text on a small 3 inch screen. What all do I need to achieve this? Is it possible to make an app that can transmit signals via wifi or bluetooth to this three inch screen? What all components do I need for the screen to change the signal to text? I have very little experience dealing with all of this.

What kind of display is your 3 inch screen exactly? Is it already an existing piece of hardware that you have hooked up, and you just need an interface for it?

Raspberry Pi may be a good start.

I want to make it all from scratch but I have thought it might be easier to use an old phone somehow.. But is it possible to set up a connection between a iPad and this device without internet.

Not an ipad as it is an apple product and I don't think that even if you pay $99 USD to become a developer, you still wont be able to access bluetooth/wlan

Possible? Sure. But to do anything with iOS development, you'll need a Mac + XCode and learn Swift. Android would be objectively cheaper if you wanted your "send" device to be a phone with an app, as Android devices can be gotten for quite cheap, and the programming language is free - you also don't need to sign up for the store or anything like that unless you plan to distribute it.

What exactly is your goal?

So I am kind of using this thread to brainstorm. Lets say I hire someone to make me the app is it even possible for me to set up a wireless connection between the app and a receiving device using bluetooth/wlan? And how difficult would it be to find the things I need for the receiver: screen, something to make it pick up the wireless connection, battery, computing system that can have text show up on the screen?

My goal is to have a system that has a transmitter: which is an app and a receiver that will put text on a small screen, I want all of this to be about the size of a phone. I was thinking in the middle having a wireless network of some sort

Lol I mean that you can't access it on a low level. Like you can't go customising drivers.

That's rarely necessary to begin with.

So you basically just want to make a small, wireless sign that displays text. That's what you're getting at?

Well, you would make a "server" app on your device you send from, then a "client" application on whatever your endpoint is that listens for that server. Whether that's something like a Raspberry Pi or just another phone is up to you on whatever would work better.
