<h2 id="introduction">Introduction</h2>
<p>In April 2017 my son and I decided to each build a digital clock. I had been interested in the idea since seeing <a href="https://www.youtube.com/watch?v=8Ty5Bnj2XqE" title="eBay clock kit. Full build and setting guide.">Big Clive</a> build one on YouTube, and I think my son had been similarly motivated.</p>
<p>He found one, which I have <a href="https://www.ebay.co.uk/itm/162310902696" title="4-Digit LED DIY Digital Electronic Micro Controller Kit Clock Time Thermometer">linked</a> 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 <em>long</em> time to arrive, so patience is needed!</p>
<p>There are <u>many</u> 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.</p>
<p>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).</p>

<p>I have provided detailed notes detailing the unpacking and building of this device, with photographs. These are available <a href="https://hackerpublicradio.org/eps/hpr2329/full_shownotes.html">here</a>.</p>
