While plugging a project into a PC during software development is common, it underutilizes the PC&#39;s capabilities and is inconvenient for Clem&#39;s soldering workbench setup.

3 posted to Documents by pchan on 11/30/2023 3:03:41 PM<br /> <p><span data-contrast="auto">In every maker project, there comes a moment when a specific tool would be immensely beneficial. Sometimes, that tool is unavailable, not yet acquired due to cost, or simply doesn&#39;t exist commercially. Clem frequently encounters such challenges, particularly in projects involving various forms of serial communication. While plugging a project into a PC during software development is common, it underutilizes the PC&#39;s capabilities and is inconvenient for Clem&#39;s soldering workbench setup. Clem&rsquo;s &quot;00Screen&quot; project emerges as a solution, providing a portable display for quick serial checks during hardware debugging, addressing challenges like misbehaving Wi-Fi projects and brownouts during boot.</span><span>&nbsp;</span></p> <h2 id="mcetoc_1hggafqgh0"><span>Watch the Video:</span></h2> <p><span><a href="https://www.youtube.com/watch?v=u9_BLuzyUSo">www.youtube.com/watch</a></span></p> <p><span data-contrast="auto">Clem&#39;s 00Screen serves as a universal Serial/USB/Wi-Fi display, aptly named after its starting point, &quot;00&quot; representing the first address in a computer&#39;s memory. Central to the design is the readability of information, as it features a Midas HD44780 compatible alphanumeric LCD with a generous 40x4 character array size. Clem&#39;s fondness for the classic backlit LCD, demonstrated in a previous build (Basic Badge Computer), influences the form factor of the device. The ESP32-S2 Wroom module serves as the project&#39;s brain, utilizing leftover parts from previous element14 presents videos, creating a curious resemblance to a laptop.</span><span>&nbsp;</span></p> <p><span>&nbsp;<img alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-03-81/vlcsnap_2D00_2023_2D00_11_2D00_29_2D00_14h46m49s543.png" /></span></p> <p><span data-contrast="auto">Utilizing components from past projects, such as the Molex FPC connector from the BLE Keyboard episode and the MCP1825S LDO used in numerous 2021/2022 projects, Clem emphasizes sustainability in design. Clem showcases the already-working unit, emphasizing that the code is mainly composed of standard Arduino libraries. He highlights the ease of adding custom functions to the device, providing flexibility for makers.</span><span>&nbsp;</span></p> <p><span>&nbsp;<img loading="lazy" alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-03-81/vlcsnap_2D00_2023_2D00_11_2D00_29_2D00_14h46m57s144.png" /></span></p> <p><span data-contrast="auto">The integrated LiPo cell allows Clem to take the 00Screen anywhere without worrying about a power source. 3D-printed adjustable feet, designed in FreeCAD, facilitate convenient mounting. The device&#39;s functionality, including source selection with buttons and indications for new data through a blinking display and beep, is demonstrated. Clem showcases USB and UDP Wi-Fi messages, emphasizing the buzzer as a convenient feature to alert him without needing to look at the display. The 00Screen stands not only as a solution to a specific problem, but also as a testament to Clem&#39;s resourceful and sustainable approach to electronics projects.</span><span>&nbsp;</span></p>

1 posted to Documents by tariq.ahmad on 11/30/2023 2:59:37 PM<br /> <p><span data-contrast="auto">In every maker project, there comes a moment when a specific tool would be immensely beneficial. Sometimes, that tool is unavailable, not yet acquired due to cost, or simply doesn&#39;t exist commercially. Clem frequently encounters such challenges, particularly in projects involving various forms of serial communication. While plugging a project into a PC during software development is common, it underutilizes the PC&#39;s capabilities and is inconvenient for Clem&#39;s soldering workbench setup. Clem&rsquo;s &quot;00Screen&quot; project emerges as a solution, providing a portable display for quick serial checks during hardware debugging, addressing challenges like misbehaving Wi-Fi projects and brownouts during boot.</span><span>&nbsp;</span></p> <h2 id="mcetoc_1hggafqgh0"><span>Watch the Video:</span></h2> <p><span><a href="https://www.youtube.com/watch?v=u9_BLuzyUSo">www.youtube.com/watch</a></span></p> <p><span data-contrast="auto">Clem&#39;s 00Screen serves as a universal Serial/USB/Wi-Fi display, aptly named after its starting point, &quot;00&quot; representing the first address in a computer&#39;s memory. Central to the design is the readability of information, as it features a Midas HD44780 compatible alphanumeric LCD with a generous 40x4 character array size. Clem&#39;s fondness for the classic backlit LCD, demonstrated in a previous build (Basic Badge Computer), influences the form factor of the device. The ESP32-S2 Wroom module serves as the project&#39;s brain, utilizing leftover parts from previous element14 presents videos, creating a curious resemblance to a laptop.</span><span>&nbsp;</span></p> <p><span>&nbsp;<img alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-04-35/vlcsnap_2D00_2023_2D00_11_2D00_29_2D00_14h46m49s543.png" /></span></p> <p><span data-contrast="auto">Utilizing components from past projects, such as the Molex FPC connector from the BLE Keyboard episode and the MCP1825S LDO used in numerous 2021/2022 projects, Clem emphasizes sustainability in design. Clem showcases the already-working unit, emphasizing that the code is mainly composed of standard Arduino libraries. He highlights the ease of adding custom functions to the device, providing flexibility for makers.</span><span>&nbsp;</span></p> <p><span>&nbsp;<img loading="lazy" alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-04-35/vlcsnap_2D00_2023_2D00_11_2D00_29_2D00_14h46m57s144.png" /></span></p> <p><span data-contrast="auto">The integrated LiPo cell allows Clem to take the 00Screen anywhere without worrying about a power source. 3D-printed adjustable feet, designed in FreeCAD, facilitate convenient mounting. The device&#39;s functionality, including source selection with buttons and indications for new data through a blinking display and beep, is demonstrated. Clem showcases USB and UDP Wi-Fi messages, emphasizing the buzzer as a convenient feature to alert him without needing to look at the display. The 00Screen stands not only as a solution to a specific problem, but also as a testament to Clem&#39;s resourceful and sustainable approach to electronics projects.</span><span>&nbsp;</span></p>
