The code handles daylight savings automatically. I’m now ready to start on the case design.

The plan is to add a small microcontroller coupled with a GPS receiver to perform as a “never have to set it” clock that runs off a USB source. I have a few more PCBs in reserve along with some blue and yellow LEDs.

Another filing in the “because you can” category, the big digit display springs to life at first attempt. Taking advantage of a 24 channel LED driver, it strings 7 sets of 5 LEDs to form digits that are just over 48mm high. Pairs with voltage booster to drive them.

So hard to get a good video of this, but gotta love some blinking LEDs. It’s an update to an old fave: non rectangular board, soft power switch, single cell battery with charging and voltage booster. SW uploads well and core functions appear to be working. Now to add the OLED and finish the code.

Impressive lightning storm a little south east of Sydney this evening.

Wait for it
