This Metro Mini microcontroller-based clock is a minimalist timepiece that celebrates, rather than hides, its components. It's a straightforward build, electronically, and it's up to you to house and display it any way you like!

You can build it onto a breadboard, a perma-proto board, or even wire it dead-bug style without a board at all.

For this build you'll need:

Optionally:

• Perma Proto board, or
• Female header pin strips, x2
• Colored filter gel, tape

Let's have a look at building the electronics next.
