I have not found a root cause yet. When I take down the rig, pull both boards out of the pineapple can, and then reinsert, the keyer will boot properly. Until then, there's just an audible buzz, no radio signal, and the keyer does not boot.

It looks like these could be cut down:

It would make for more simple amplifier maintanence.

The TalentCell 12 V LiFePO4 battery was dipping from a nominal value of 13.16 V to 8.69V on key down. Just after being charged it was dipping from 13.6 V to somewhere in the 12 V region. Come up with a data driven way to know when to charge the battery. Since we have data about when the battery was used and for roughly how long in rm_rnb_history_pres, we perhaps could infer how long the battery had been used before it reached the point it was at last night (10/2/2023.)

The radio occasionally resets the keyer. This only happens when both dit and day are pressed at the same time. I think the keyer weight being lower may help this issue. Also going to turn down bias on the amp.
There is a lot of seeming randomness to all the issues reported with Project TouCans

We'd like to make TouCans self-contained. To that end, the we've been looking at using a PicoW to control rig functionality by offering an html interface served over WiFi from the rig itself. The first step is to start a web server on the PicoW.

Starting the PicoW as a connection point

Here's the important code from that page:

import network
import rp2
import time

rp2.country("DE")

ap = network.WLAN(network.AP_IF)
ap.config(channel=13, key="PicoWPicoW")
ap.ifconfig(('192.168.17.1','255.255.255.0','192.168.17.1', '8.8.8.8'))
ap.active(True)

while True:
    ap.connect(ssid="PicoW", key="PicoWPicoW")
    print(ap.status())
    print(ap.isconnected())
    print(ap.status('stations'))
    time.sleep(1)
