Update

As of May 2020, these all include both a DS3231M real time clock and a SHT21 temperature/humidity sensor which was an enhancement that came out of the Kickstarter campaign.

What is it?

The Pixel Clock is a four digit clock made up of 86 WS2812 addressable LEDs (3535 size) arranged into a 7-segment display with a colon. The board is designed to be connected to the microcontroller of your choice, or it's fully provisioned for an optional ESP32 module (ESP-WROOM-32). Just solder a ESP32 to the back, flash the code and go.

Pins from the ESP32 are broken out to add additional features such as a photoresistor to control brightness, an I2C real-time clock, or speaker for an alarm. These features aren't yet implemented in the code but shouldn't be difficult to add.

Why did you make it?

I wanted to design a clock for my kids that would let me change the colors based on bed time or when it's a good time wake up or nefarious parent tricks like setting the clock back an hour on the weekends. I chose to base it around the ESP32 so that those features could be implemented via web or app interface someday.

What makes it special?

This is the first clock kit that I know of that uses WS2812 LEDs arranged as a 7-segment display with multiple LEDs/segment and a size close to traditional bedroom clocks.

Saved me a heap 'o trouble

I've recently been designing some NTP clocks for around the house, and this was PERFECT for my next one (building one for my daughter). Setup was relatively painless (just needed a USB port to power it, I ordered mine with the ESP32 module attached). Quality is top-notch and this thing is suuuuper-easy to use. Bravo!

Just what I was looking for!

I was going to make this exact clock with sections of RGB LED strip and was NOT looking forward to the process of wiring it all up. This is perfect. It is extremely easy to connect to it as if it were any LED strip. Within a couple minutes I had colors running just fine. A couple hours after that, I had the clock displaying the time with custom color effects cycling over it.

I'm still using an external ESP32 dev board, but definitely like the possibility of attaching the ESP32 directly to this in the future.
