My major DIY upgrade to my Gaggia Classic - PID, Steam

So, I added a PID, which controls boiler temp more exactly. I wired it to use the alarm function as a steam thermostat, so I can control steam temp more accurately too. Then I used a PWM to control intrashot temp stability. The PID can't react fast enough to the temp swing as you pull a shot, so even with a PID your temp drops.
