Assuming a basic understanding of combinational logic, Derek constructs a simple flip-flop using a 74 LS series logic IC, giving examples of its applications, including memory storage devices and shift registers. Cross-coupled NOR gates are used to create a set-reset (SR) flip-flop. Derek showcases the flip-flop working with momentary input signals and asynchronous reactions.</span><span>&nbsp;</span></p> <h2 id="mcetoc_1hfphbdov0"><span>Watch the Video:</span></h2> <p><span><a href="https://www.youtube.com/watch?v=S28QFe7EdNI">www.youtube.com/watch</a></span></p> <p><span><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_21_2D00_13h47m52s279.png" />&nbsp;</span></p> <p><span data-contrast="auto">Derek delves into the circuitry, demonstrating the SR flip-flop with two transistors, resistors, and LEDs.

Whether you&#39;re a college student, an electrical engineering enthusiast, or a hobbyist tinkering with resistors, you&#39;re likely to encounter such intricate circuits. These circuits may involve multiple power supplies interacting with each other, necessitating an understanding of how current and voltage are distributed across different components. Derek kicks things off by sharing his personal experience of crafting an audio dummy load for troubleshooting guitar amplifiers, which required creative switching of resistors for impedance combinations.&nbsp; One of the challenges in this project was managing power dissipation among these resistors.</p> <h2 id="mcetoc_1h8hmmgcd0">Watch the Video:</h2> <p><a href="https://www.youtube.com/watch?v=I7qBz6s99wk">www.youtube.com/watch</a></p> <p><span data-contrast="auto">In the episode, Derek simplifies the process of dealing with complex resistive circuits. He compares the flow of current to water flow, with the resistors represented by water valves that allow different amounts of water to pass. He highlights the difference between series and parallel resistor arrangements. In a series configuration, the total resistance is the sum of individual resistances, but each resistor experiences the same current while bearing different voltage drops. On the other hand, parallel resistors share the same voltage while dividing the current based on their respective resistances.</span><span>&nbsp;</span></p> <p><span>&nbsp;</span></p> <table> <tbody> <tr> <td><img alt="image" style="max-height:219px;max-width:389px;" height="219" src="/resized-image/__size/778x438/__key/communityserver-wikis-components-files/00-00-00-04-35/vlcsnap_2D00_2023_2D00_08_2D00_16_2D00_11h35m13s898.png" width="389" /></td> <td><img loading="lazy" alt="image" style="max-height:212px;max-width:377px;" height="212" src="/resized-image/__size/754x424/__key/communityserver-wikis-components-files/00-00-00-04-35/vlcsnap_2D00_2023_2D00_08_2D00_16_2D00_11h39m47s078.png" width="377" /></td> </tr> </tbody> </table> <p><span data-contrast="auto">The complexity increases as Derek delves into intricate resistor combination circuits, introducing Kirchhoff&#39;s voltage law and Kirchhoff&#39;s current law.

He also provides two LTspice simulations, which show the drawbacks of using a simple diode vs. a precision rectifier so you can try it out on your own.</p> <h3 id="mcetoc_1h52g7p090">Watch the Video:</h3> <p><a href="https://www.youtube.com/watch?v=_lJ9NcN7fO4">www.youtube.com/watch</a></p> <h3 id="mcetoc_1h52gbtfu1">Bonus Content:</h3> <ul> <li><a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-04-35/BasicDetector-Derek.asc.zip">LTspice File</a></li> </ul> <div style="background:#ffffff;border:1px solid #dadada;margin:0;padding:14px 16px 16px 18px;vertical-align:top;"> <div style="display:inline-block;float:left;padding:0px 25px 8px 0px;"><a href="/challengesprojects/element14-presents/"><img alt="element14 presents" src="/e14/assets/legacy/2021/e14PDCtoDaylight2021.png" /></a></div> <div style="display:inline-block;vertical-align:top;width:70%;"> <p style="margin:0;"><span><a class="jivecontainerTT-hover-container jive-link-community-small" href="/challengesprojects/element14-presents/">element14 presents</a></span>&nbsp; <strong>|</strong> <a class="jive-link-wiki-small" href="/challengesprojects/element14-presents/vcp-program/w/documents/4139/vcp-biography-derek">About Derek</a>&nbsp;&nbsp;<strong>|</strong>&nbsp; <a class="jivecontainerTT-hover-container jive-link-community-small" href="/challenges-projects/element14-presents/dc-to-daylight/">DC to Daylight</a></p> <p style="margin:0;"></p> </div> </div><div style="clear:both;"></div> <div style="font-size: 90%;">Tags: lvdt, mutual inductance, lock-in amplifier, preconditioner, precision rectifier lvdt detector circuit, linear variable differential transformer</div> https://community.element14.com/challenges-projects/element14-presents/dc-to-daylight/w/documents/28265/how-to-build-a-linear-variable-differential-transformer-motion-sensor-and-detector----dc-to-daylight-29/revision/2Tue, 11 Jul 2023 13:03:21 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:8e7b3f35-d6d4-4cdf-b7da-15d637fdbb5ftariq.ahmadRevision 2 posted to Documents by tariq.ahmad on 7/11/2023 1:03:21 PM<br /> <p>In this application-based episode, Derek shows how to build a sensor which measures linear motion using mutual inductance.
