A Cindy's alarm clock/recording weather station

And another Cindy's Alarm Clock/Weather Station rolls (slowly) off the production line just in time for Christmas.

This is the 6th iteration of this clock series.

It's being given as a Christmas gift today (17Dec22) to some good friends. Like #5, it's laser engraved in the hand fitted zebrawood case. The CNC drilled the panels perfectly on the first try. The 3d printed parts are most all one color (for a change).

The case is noticeably thinner than any of the previous versions, to good effect. More care was taken in the fitment of the plastics and the final trim sizes as my understanding of the dimensional interactions and cutting sequence has improved. Even with an Incra and Wixey, the cipher'n has to be well thought out, and the blade settings are measured in thou's!

My fab techniques are becoming really refined in this one.

The case is held together with 4-40 machine screws in tapped holes in the zebrawood. Care is taken not to over tighten.

The front and rear panels are fully connectored and labelled so the two can be separated and reconnected quickly and easily.

The data captures can be plotted out using a web program I wrote. The output looks something like:

I live in Florida and during the winter we have two types of weather, warm and wet, clear and cold. This plot shows both. On the 22nd and 23rd the humidity and temp are both high (warm and wet), while the barometer is low (stormy). Then the weather completely filps over about 12 hours, with the barometer rising (clear), with the temp and humidity dropping like a stone (cold). This is actual data collected by my development system.

I can build one, puttering, in about three, half days. One for mechanical fab, one for electrical fab, and the third for the case and final fitment and touches.

The out of pocket on this one is around $175, not counting the share of the capital costs of the laser/CNC/3d printer.

Anyone interested in making their own, the plans are free. DM me here for a copy, including schematics, drawings, 3d print files, parts lists and firmware. I'm also open to making kits available with various levels of parts (3d printed parts, preloaded CPU, etc.) for a nominal cost.
