First breadboard prototype matching different parts of the circuit to schematics

First prototype has now been put together and the result don't look too bad. Measuring output while the input voltage is being adjusted from 6V to 12V produces between 5V and 5.5V output., with a lot of noise as the input voltage increases.

Output (channel 1, top) trying to keep up with 5.1V reference as the input (channel 2, bottom) increases from 6.5V to ~12V

It's not the best converter yet, but, in principle, it does what it's supposed to ^^  There's room for improvements...
