So I got a development board from Waveshare that has a screen and motherboard ([Espressif] ESP32-S3 with a 466\u00d7466 AMOLED screen), and programmed a UI [User Interface] that looks suitably sci-fi for my gaudy tastes.&#8221;<\/p>\n<p>This chunky pocketwatch is powered by an Espressif ESP32-S3 microcontroller and round display, and housed in 3D-printed stainless steel. (\ud83d\udcf7: Math Campbell)<\/p>\n<p class=\"hckui__typography__bodyL\">The watch is built around the dimensions of Waveshare&#8217;s ESP32-S3 1.75&#8243; 466\u00d7466 AMOLED Round Touch Display Development Board, which in turn houses the dual-core Espressif ESP32-S3 microcontroller behind a circular AMOLED display connected via a quad-SPI interface. Being round, rather than square, makes it ideal for watch projects \u2014 but Campbell wasn&#8217;t happy with just cramming it into an old pocketwatch housing, so turned to 3D printing for something truly custom.<\/p>\n<p class=\"hckui__typography__bodyL\">&#8220;[I] added a battery and designed [the] case in [Autodesk] Fusion360,&#8221; Campbell explains, &#8220;and had it 3D-printed in stainless steel. Not perfect and I still need to do the buttons and a few other parts and then remake the case in sterling silver (I am a silversmith), but this is the first time seeing it assembled and working somewhat so I wanted to show it off.&#8221;<\/p>\n<p class=\"hckui__typography__bodyL\">More details are available <a href=\"https:\/\/old.reddit.com\/r\/arduino\/comments\/1r6krfi\/smart_pocketwatch_i_made_with_custom_ui_in_arduino\/\" class=\"hckui__typography__linkBlue\" rel=\"nofollow noopener\" target=\"_blank\">in Campbell&#8217;s Reddit post<\/a>, while source code for the smartwatch is available <a href=\"https:\/\/github.com\/mathcampbell\/Smartwatch-V5\" class=\"hckui__typography__linkBlue\" rel=\"nofollow noopener\" target=\"_blank\">on GitHub<\/a> under an unspecified license.<\/p>\n","protected":false},"excerpt":{"rendered":"Scottish maker and silversmith Math Campbell has built a smartwatch with a difference: this one goes in your&hellip;\n","protected":false},"author":2,"featured_media":481894,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[17],"tags":[49,48,195,61],"class_list":{"0":"post-481893","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-gadgets","8":"tag-ca","9":"tag-canada","10":"tag-gadgets","11":"tag-technology"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/481893","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/comments?post=481893"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/481893\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media\/481894"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media?parent=481893"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/categories?post=481893"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/tags?post=481893"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
