3D Printed Alarm Clock Looks Just Like Store Bought




Clocks are a popular project on Hackaday. They’re a great way to showcase a whole range of creative build techniques, and can make an excellent showpiece as well. We’ve seen everything from the blinkiest binary build to the noisiest alarms, but [Benoit] has delivered something different — a stylish build that looks like it came right off the store shelf.

The clock features a large 7-segment display built with IN-PI554FCH LEDs, which are similiar to the popular WS2812Bs but with lower power consumption. There’s also an OLED display for reading the date and going through menus, capacitive touch buttons for control and an Arduino Mega to tie everything together.

The real party piece is the enclosure, however. [Benoit] spent significant time honing a process to get a nice surface finish on Shapeways SLS parts. The 3D printed components are first cleaned with a toothbrush to free any loose powder, before several stages of primer, sanding, and paint. The final product is then finished with decals that lend the device that perfect factory look. If you’re eager to replicate the build, the parts are available at Github.

[Benoit]’s clock is a great example of what can be achieved by the home builder who is willing to wait a couple weeks for high quality 3D printed parts and decals to ship. It’s not [Benoit]’s first build to grace these hallowed pages, either – his transparent clock runs Linux!
