What is it?

The QuadClock Bricta is a great-looking clock featuring four TFT displays. It’s part of the QuadClock series, where each display shows a single digit.

With 14 carefully chosen fonts, you can adjust the style to match your preference. WiFi is turned off by default (it runs fine without), but when you turn it on, the time stays in sync, and you can wake up to an internet radio station. Firmware updates are done through the website by connecting a USB-C cable or via VSCode/PlatformIO if you want to tinker with the software.

Key Features

Display

• Four 1.69" displays (240×280 pixels)
• Flicker-free viewing
• Night mode: dims & shifts to red at night
• Light sensor for automatic brightness adjustment

Timekeeping

• Accurate timekeeping using a DS3231 with a temperature-compensated crystal
• Auto daylight savings adjustment
• Backup battery maintains time during outages
• 12h or 24h format display

Alarms & Sounds

• Individual alarms for each day of the week, plus one daily alarm
• Wake up to a rooster, cowbells, ptarmigan call, The Moldau symphony, or an internet radio station
• Optional hourly chimes
• Optional soft 'flip' sound on the minute change (remember split-flap clocks?)

Customization

• 14 fonts, carefully selected for clarity and style, ranging from modern to retro
• Color/brightness controls
• Rotary encoder for menu navigation

Power & Size

• USB-C powered (cable/adapter not included)
• Web-based software updates via USB-C cable
• 15.0 cm wide × 2 cm deep × 4.5 cm tall (excluding stand)
• Includes a small stand to angle it on your desk

I’ve tested a variety of colors. On the basic black version, the displays blend in beautifully. The wood version (while still made of PLA with added wood fibers) gives it a more natural look. The red granite version has a slightly rougher texture for a more organic feel, and the green version has a mossy, rough finish. They all look great!

Why did you make it?

I wanted to create a product that I could design from the ground up. I first built a TFT clock a few years ago, and recently, I spent three months designing the QuadClock. It was an exciting process, creating the schematic, designing the universal PCB (the QuadClock PCB), developing the software, modeling the case, and putting together the documentation.

The software is fully open source, so you’re free to modify or enhance it as you see fit. If you have a contribution, feel free to submit a pull request on GitHub, and if appropriate, I’ll merge your additions into the main branch.

Important to know

While it’s not hi-fi or particularly loud, the speaker produces enough sound to wake you up if you use it as an alarm clock. You can opt for a better speaker, but as expected with a small plastic case, the sound quality is still similar to an old transistor radio.

3D Print Disclaimer: This item is 3D printed at home, so minor variations in finish, fit, and material quality are to be expected.

While I strive to make the clock as polished and well-made as possible, it’s still a project handcrafted by a hobbyist, not a mass-produced product. Every detail has been carefully considered, and I’ve put a lot of passion into the design. I hope you’ll enjoy using it as much as I enjoyed creating it!
