Yes agreed ( in part..) We all have to start somewhere.

Radiotech:
The project is now finnished, a small 40m Hellschreiber 700mW beacon! :) I tried pushing up the voltage to 14v, and got 1W off output but it got really hot. I started thinking about using a down powered Pitico as a oscillator together with an RF power amplifier to get a bit more power from it, that might be a nice project making it a bit more interesting.

Making small electronic projects is a hobby i enjoy, i like tinkering and figuring out how the things work. I am not a RF or Electronic professional, i work in a completely different field. I started this build thread on the Swedish ham radio forum ham.se like QRP pointed out, but migrated it here because i thought more people would enjoy it and have design sugestions.  :)

Teotwaki:
You can swap the 2N2222 for a 2N2219 and with a good heat sink it can dissipate 3 watts of heat
