https://tube.loping.net/videos/watch/6fc7e0bb-e54e-4009-bdf0-30ca4834e526 I describe an old project in which a few friends and I designed an RFID tag that fits into a magnetic stir bar and measures temperature wirelessly. We decided to open-source the project, and you can see the PCB design and tag firmware at the github repo below. I don't think I have the firmware for the base station, unfortunately. https://www.ti.com/product/TMS37157 https://www.digikey.com/en/products/detail/texas-instruments/EZ430-TMS37157/2183733 https://github.com/benkrasnow/Temperature_sensing_stirbar https://www.patreon.com/AppliedScience Sun, 12 Jul 2026 09:48:26 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://tube.loping.net https://tube.loping.net/lazy-static/avatars/8a56e488-2120-4649-a417-badf5893657b.png https://tube.loping.net/videos/watch/6fc7e0bb-e54e-4009-bdf0-30ca4834e526 All rights reserved, unless otherwise specified in the terms specified at https://tube.loping.net/about and potential licenses granted by each content's rightholder.
