I just remembered I bought a USB endoscope for my site investigation bag and never ended up using it. It is <span style="font-size:10pt;color:rgb(0,0,0)"><a href="https://www.amazon.com/gp/product/B01MY95HFJ/" target="_blank">this one</a> at Amazon for $12 - there are newer/better ones out there I'm sure</span>. Anyway, it plugs into a phone or laptop - I just tried it on mine and, with an extra set ot helping hands, might be a cheap compromise over the video microscope. <a href="https://www.dropbox.com/s/8qy57doz9jslip4/WIN_20181211_11_40_51_Pro.jpg?dl=0" target="_blank"><span style="font-size:10pt;color:rgb(0,0,0)">This (dropbox link)</span></a> is an image I took handheld. The module is already shrink wrapped, but that's the edge of the GPS board - and it was full screen on my 12" laptop so pretty easy to see. The scale in the "distance" is a 1/100" machinists scale, and its laying 1/2" beyond the GPS connections in the foregreound, so it has decent enough depth of field - certainly better than the head magnifier I have. <div><br></div><div class="m_-1402346846081578909mb_sig"><span style="font-family:Palatino Linotype">--</span><div><span style="font-family:Palatino Linotype">Jordan</span></div></div><blockquote class="m_-1402346846081578909history_container" type="cite" style="border-left-style:solid;border-width:1px;margin-top:20px;margin-left:0px;padding-left:10px">

<p style="margin-top:0;margin-bottom:0">Yeah.. a bench magnifier lamp is barely adequate.. (not sure about the EggTimer component scale).. </p>
<p style="margin-top:0;margin-bottom:0">Using the Harbor Freight headband can be a little awkward, but works really great for the up close stuff and is by far the cheapest way to do it:</p>

If I had it to do again.. I would probably just buy one of those.. they look pretty sweet (and are more portable than my luggable station).</p>

I have lighted magnifier headband, table top, and specs but they were either not enough magnification or too much. What are you folks using/recommending for this?<br>
