Building a Digital Clock Kit


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.

Just bought one

I've just bought one of these because of this episode. £4.27.

Depending on timings, I might bring it to Podcrawl so you can inspect my work! ;-)

Hmm, Glasgow Podsoldering anyone?

Hi Dave,

I hope you have fun with the build.

I'm imagining a bit of last-minute soldering at the back of a bar in Glasgow :-)
