chocolate_tempering: Use normal DIL06 package for MOC3041
...
The MOC3041 data sheet mentions two DIL packages: One with 7.62
and one with 10.16mm spacing. The 7.62 appears the standard version,
so let's switch to that.

chocolate_tempering: Add F2 fuse in TRIAC circuit
...
AC mains might be fused at 16A, while our dual-layer 3.81mm traces
don't really sustain more than 10A (assuming 35u copper). Let's
fuse by default with 6.3A which is fine for any heating up to 1.4kW.
In my use case the heating has 70W or 300W, so I could even fuse lower.

chocolate_tempering: Fix TRIAC polarity
...
While the TRIAC is often thought as a unipolar device behaving identical
in both directions, it actually is not in terms of the gate
voltage/current. Let's fix that mistake in the v1 design.

LTS418S: Enlarge solder pad length to simplify hand soldering
The original footprint is designed for solder paste / reflow.
For hand-soldering with an iron, longer pads make the task a bit
simpler. Length is only elongated outside of the package, so
insulation clearance is unaffected.

initial checkin of ESP8266 based PID controller for chocolate tempering
...
Based off Justin Richards' EasyCook design described at
https://hackaday.io/project/167840-slowcooker-esp8266-based-pid-controller
https://github.com/ornea/slowcooker
Main changes:
* do an actual PCB layout
* add an on-board AC/DC converter for powering the ESP
* use a "snubberless" BAT16BW
* ability to connect multiple temperature sensors
