Inside a large "3D" digital clock.

This is a very smart looking clock, and unusually for a generic eBay product it's actually got a good sensible interface with just enough features to make it useful.
That includes easy time setting and an alarm that is easy to disable.
Unlike many other clocks it doesn't display lots of random things like dates and temperature, although some can apparently display temperature. Instead it just displays the time all the time just like a clock should.
The construction also looks good, with a totally unexpected way of driving the display to avoid any flicker at all. The unit is powered by a 5V USB power supply, and draws very little current. Low enough to consider using the clock at events or as part of a costume with a USB power bank. (It would have to be the type that puts out 5V all the time.)

There is a hidden screw.... I broke it. No great deal, it went back together again OK.

Target price is around $12.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
