Inside an eBay sonic health bracelet for lymph drainage and fat reduction

The original listing for this watch stated "Slimwe Ultrasonic Body Shape Wristband, Lymph Drainage Magnetic Bracelet" Which may be copied from the listing for an equally suspicious product. They've since tamed the listing to "Slimwe Ultrasonic Body Bracelet Shape Wristband, LED casual sports touch Bracelet" The listing originally showed various medical-style pictures implying that the unit liquifies fat cells, prevents lymph node blockage and promotes blood circulation. In hindsight, I noticed that the missing LED may have been as supplied, so maybe this is just their way of getting rid of factory rejects. Nice PCB though. Mid-play video-adverts are annoying in technical videos, so I don't enable them. If you appreciate that and enjoy my content then you can help support the channel with a contribution of a dollar or two a month on Patreon. That also lets you critique the (advert free) videos before they are released, gives a more direct means of communication with me and also gives access to the regular relaxed Patreon live streams.   / bigclive   #ElectronicsCreators
