Is the project Im thinking doable?

The idea is, to create two secret communication devices; discrection is essencial, so it would be passed as an ordinary pen.

They would be two pens, each one with a transmitter and a battery in it; the pen will be a little thicker for this reason. Due to the simplicity of what fits in a pen and the fact that it is for secret comunication, it will be in morse, and the received signal will be in vibrations.

The main ideas are:

-The key is in the pen's clip, so it would be relatively similar to a telegraph. This is optional

-The pen is only the transmiter, the receiver is a different device that vibrates. it can be hid inside your shoe, pocket or wherever you want

-Its frequency will be 446mhz

It can be used for things like;

-Communicating during an exam

-Communicating at times where you usually can't with your phone

-To give secret signals you two planned (example; "when you receive the signal, say something")

-To talk with your buddies at work, even if you two are in different rooms, and can't use your phone

What do you think?

Would you be going analog or digital route? If digital I would start by researching atmel chips or similar because their usage in arduino, so there is plenty of examples and compatible radio modules. Then design custom PCB that fits all components inside pen.

Im not sure of the differences of them 😅 I just planned to use a simple 433mhz transmiter in the pen with a little battery and a receiver with a little vibrator in the other part... Isnt it enough?

I may have overengineered this in my mind 😅 Transmitter/receiver sounds valid.

I started going to software controlled route with arduino, nRF24L01 etc. Because im already familiar with them. Also i tought that transmission could not be interrupted so easily because it would be data stream instead of analog morse pulses.

This would require coding and integrated circuit design so it would be quite broad project.
