Voltlog #241 - The World's Cheapest Digital Watch (Teardown)
$2 for 5 PCBs Any Color https://jlcpcb.com The only thing that seemed interesting when I first saw this was the price which was $0.90 delivered. I could not believe that you can get a wrist watch for 90 cents delivered from China.
High quality PCB Services https://pcbway.com Join me in this 2 part series where I show you how I automate the main water valve in my apartment to be able to control it from HomeAssistant. This can be extremely useful in conjunction with water leak sensors to prevent extensive damage in case of a water leak by turning off the main water supply.

Owon have had a bunch of power supply models in their lineup for a while but this new addition, the SPE series caught my eye because it’s in the affordable budget range and I really wanted to give this one a try to see if any good and if it will earn it’s spot on my workbench. So join me in this video to learn more about it.

Inside the box you get a IEC mains cable, a USB cable, user manual with 1 spare fuse and no test leads, which is good, because typically those included test leads are pretty low quality. The enclosure is made of metal, with the exception of the front panel which is plastic, generally gives me a good feeling, nice metal work, nice rubber feet to prevent it from sliding around, I’m definitely liking how this is built at first sight.
I quite like the general layout of this PSU, LCD located at the top of the front panel, we get some soft keys which are nice and rubbery, there seems to be enough spacing between the keys, the on/off switch that controls the output has an LED behind it but they somehow decided it will be a good idea to have it shine blue when the output is on, I would very much prefer if manufacturers would stick to red/green LEDs for the ON/OFF buttons on power supplies.
The rotary knob is pushable, we’ll see if that’s used in any way in the GUI but the feeling is that of cheap plastic, I would have preferred a nice rubber or metal knob on here, but hey, let’s not forget the price range of this unit.
There is a USB 5V 1A port on the front which I expect to be power only but that’s a nice touch because you often need to power some USB device on the workbench, would have been nicer if it would be rated for 2.4A but still, nice to have even at 1A.
The banana plugs they use, do unscrew and they have a hole so you can insert a wire for testing but they feel just OK, not great but not terrible either. There is an earth connection banana plug but because th
