Hello everyone!

I work in Network Security and Software Exploits in my school, mostly to just see how it works
and how something as simple as a feature on a phone could cause a million problems.
(I'm looking at you Bluetooth...

)
So because I have to work with all kinds of weird devices that are either overly pricey and unreliable,
or just from some country that has been known for selling dangerous knockoffs or exploited hardware,
I have decided to start designing a new tool of my own called Tackle Boxes.
The first one I'm working on is for Bluetooth, every single thing with a chip in it pretty much has Bluetooth
and with that comes a lot of vulnerabilities. So I want to make a device that can:
- Connect to a computer through USB (Micro controller takes care of that most likely)
- Has a display that can be programmed (Maybe a small recycled Nokia phone display w/ backlight)
- A micro controller that can support Processing compiler (Most likely Arduino, but open to alternatives)
- Has a battery in it for portable usage (Preferably Lithium Ion)
I do not intend to sell it or market it, but it's just for a demonstration on how vulnerable ANYTHING can be.
If you guys can suggest good Bluetooth Modules, Micro controllers, Rechargeable Batteries or even tips
on how to tackle (God I made a pun...) this project, much appreciated! ^^
There is another thing I wanna do to make this, and it's to make it a tad stylish and compact, like lights and/or
a good housing, so again tips are appreciated.
I haven't sketched it out JUST yet, but I'm working through a couple drafts.
