I know!

It took most of this summer to get my tide clock to predict accurately, using NOAA harmonic constituents data crammed into an Arduino, a GPS module, and published formulas.

Take a look:

How about adding a column with a count of comments so we can sort and get a rough idea of the most popular posts?

I'm launching a new product for my clock-making business: https://DigitalHorology.com

None of my clocks tell the time.

They're all fully automatic GPS-enabled timepieces. For a couple of years I've been developing, hand-making, and selling these clocks that track the moon phase, the sun's position, etc.

My new idea is the tide clock "NautiKron." It's getting a lot of interest from US coastal buyers.

These are great! I love the natural aesthetic with wood as well. I'm curious: how do you sync them to gps?

Thanks! I'm really glad you like the LunaKron. I make a couple other versions that have less wood aesthetic and more futuristic black acrylic with a photorealistic, silvery moon.

I connect a tiny GPS module to the Arduino via 3 wires: power, ground, and serial input, and use Mikal Hart's "TinyGPSPlus" module to parse the NMEA data streams.

NautiKron seems to show the current hour in the top row. Why not project it on the tide curve?

Putting the marker inside the tide curve would give it a cleaner look.

I considered it, and figured it was more legible to have the hour marker directly under the numbers. People looking at the NautiKron from across the room or who have low vision might like it better this way.

Good idea to revisit -- I'm always tweaking the designs and responding to owner feedback.

Thanks for the comment!

Love these! Where did you get the idea? Would love to know more.

Thanks! I posted the story here: https://www.etsy.com/shop/DigitalHorology?#about

I'm building an automatic tide prediction clock that doesn't need an internet connection.

I made this one to brighten up any office:

It’s always nice to find another true lunatic.

I made a series of clocks that only track moon phase.

In Soviet Russia, monitor monitors YOU.

Bwah hah hah!

Howtoware looks like a rabbit hole for me. Thanks for the tip!

I sell my hardware projects on Etsy, mostly LunaKrons, the GPS-enabled moon phase clocks, and also a few “Game of Life” displays.

I’m boxing up LunaKrons to get ahead of this year’s gifting rush, and I’m really pleased with how the packaging is turning out.

I design and build GPS-synched moon phase clocks (“LunaKron”) & other electronic novelties, and sell them on Etsy.

I’ve consulted with ChatGPT when I need help choosing materials and with some techniques.

Those LunaKron clocks are so cool! Do you do this as a full-time job or side hustle? Looked into mass-market manufacturing and distribution?

Thanks! It’s a side hustle.

Haven’t looked into scaling up.
