The Flipper is just a tool
I know some people who owns a Oszilloscope, but only touch it, when I ask to borrow it.
In personal, I would not spend 1000e on a device I need once a year.
Through the Flipper I’ve learned I don’t need a Oszi, in much cases a Logic Analyzer is good enough and with the right software even better… 12e is okay.
It is the same with a hammer. Do you want to secure a tent, bring a nail in wood or a screw into a solid wall? Do you want to bend metal?
Every scene has a own hammer. Just go to the tools shop and ask the expert… But I think you have only one hammer in your tool box, and it is enough to mount a picture and repair everything from your car to your laptop…
You don’t need to Programm to use the flipper. But if you don’t know if you cod use it, you don’t need a flipper zero.
The development is just a the beginning. A lot of cards and fobs are not supported. The IR Port is good to use, bit it is a expensive TV-B-Gone.
A lot of people want to ‘Hack Cars’. Unfortunately this is one of the things the Flipper is not very good at and never will be, mostly because this is illegal. But because it is OpenSource you are free to desync your Carkey, as much as you like.
I like my flipper, I won’t give it away, ever…
But in your case, wait for the Flipper One. It will be a full blown Linux base. If you can’t ode the antennas, at least you have a fancy calculator …
