<p>[QUOTE=&quot;Dansco_Dude, post: 25497234, member: 147679&quot;]I showed off my latest build of Numi at yesterday&#039;s Denver Coin Club meeting</p><p><br /></p><p><img src="https://i.imgur.com/ASnjmot.png" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /> </p><p><img src="https://i.imgur.com/twK9qqi.png" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /> </p><p><img src="https://i.imgur.com/oxrLJoW.png" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /> </p><p><br /></p><p><b>Latest Changes [As of 7/26/2024]</b></p><ul> <li>Optimized cameras for better focus<br /> <br /> </li> <li>Fully built out the second design iteration after getting all needed Lego parts<br /> <br /> </li> <li>Added LEDs for lighting<br /> <br /> </li> <li>Updated code to handle the entire identification and sorting flow [Capture images, send images and prompt to AI model, move coins to correct position for sorting]<br /> <br /> </li> <li>Migrated AI models from GPT-4o to Gemini Flash 1.5</li> </ul><p><b>Current results</b></p><ul> <li>Lighting from LEDs are too weak, yielding inaccurate results<br /> <br /> </li> <li>Cameras work<br /> <br /> </li> <li>Motors for moving the coins beneath the cameras work, but the final motor for sorting is buggy. Needs to be fixed<br /> <br /> </li> <li>Time needed for analysis improved from an average of 30 seconds per coin to 10 seconds<br /> <br /> </li> <li>The Gemini Flash 1.5 AI model is shockingly accurate and blazing fast</li> </ul><p><b>Upcoming Changes</b></p><ul> <li>Add high powered lights to brighten up coin photos<br /> <br /> </li> <li>Add and program a coin hopper to fully automate the sorting process<br /> <br /> </li> <li>Goal is to optimize the machine to sort 100 coins in a row with no issues. Get Numi ready in time to show off at the Denver Coin Club Show happening in mid-August. [I got a table!]</li> </ul><p>My hope is to get Numi into a good enough state that I can challenge attendees at the show if they can sort 100 wheat cents faster than Numi. If they can, they get a coin prize. Should be a fun way to get young numismatists engaged.[/QUOTE]</p><p><br /></p>
