(Bikeshedding, I know, but I find it confusing when the soldering iron is off and press short on that it enters standby mode, but without heating it to standby temperature)

I've replaced the output transitor with a ProFET, Infineon BTS420. This guy needs an higher integral part for the PID, or it is 4-5°C off.

Print a battery symbol, dependent on charge level. Print it cyan when charging, print it green when fully charged. On Battery, print it colored from red to green, depending on charge level. Untested: If no battery is present, print the power chord symbol only (cannot test because my hardware is a bit f***ed up.)
Weller tips are rated for 40W (at least most of them). On higher input voltage, this is exceeded. This feature limits it by put a cap on the pwm, dependent on the input voltage.
We observerd a strange error yielding in dead tips* we attribute
to shorts between two contacts on the 3.5 mm connector** (bad cable...)
and we hope this failure mode will be covered by this feature.
The feature works by monitoring the temperature and making sure that
in a certain time a certain temperature rising is seen.
The tuning can be done by a few parameters:
- WATCH_TEMP_PERIOD -- The time the temperature has to rise
- WATCH_TEMP_INCREASE -- by this value
- WATCH_TEMP_DEACTIVATE -- if we are that close to the target temperature, disable
this protection.
- WATCH_TEMP_REBOUND -- if the temperature drops below the target
window (e.g by cleaning with a wet sponge), wait this time until
the protection is re-armed.
* heating up at full power, until red-glowing and then dying)
** it might be tip and ring1, combined with phase reversal on the OpAmp
caused by exceeding the OpAmps Common Mode voltage ratings.. But this is
only a theory...
The rebound timer was never re-activated and not initialized with the correct value.
fixing some corner-cases, making it more reliable and less often to drop out due to false positivss. make the rebound time a bit longer as well.
