HPR2329: Building a Digital Clock Kit

Building a Digital Clock Kit

Introduction

In April 2017 my son and I decided to each build a digital clock. I had been interested in the idea since seeing Big Clive build one on YouTube, and I think my son had been similarly motivated.

He found one, which I have linked to below. It's smaller than the one shown by Big Clive, comes from ShenZhen China, and costs $5.35 (about £4.18) postage free. It takes a long time to arrive, so patience is needed!

There are many digital clock kits on eBay, and lots of YouTube videos showing how to build them. I think it's a great project for someone wanting some soldering practice which is a little more demanding than a beginner project.

One type to avoid, I think, is the surface mount type. The one I have uses a through-hole PCB, but I have seen some that provide SMD (surface-mounted device) components. That type of soldering is beyond me at the moment (though my son has been teaching himself to do it).

Long notes

I have provided detailed notes detailing the unpacking and building of this device, with photographs. These are available here.
