My idea is to take power from my tv converting it to the required 5v and attach the pi board direct to it, basically trying to make my tv a smart tv. Not sure if I can get it to work but worth a try.
I see, well be careful with that 230v hurts when you catch hold of it
Unless you have some experience with mains voltage and electronics I'd advise looking for a small, off the shelf transformer, or if your TV is modern enough to have USB ports you could utilize those for power.
Blowing stuff up is cool, unless its yourself
