In 1942 the folks at Hewlett Packard solved this problem, and introduced their first product - the HP200A variable frequency oscillator. It utilized an incandescent light bulb as part of the feedback stabilization network in a wein bridge oscillator. In this episode, I wanted to explore the wein bridge and light bulb as a solution for an extremely simple 1kHz oscillator.</p> <p></p> <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/" data-e14adj="t"><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/" data-e14adj="t">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" data-e14adj="t">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/" data-e14adj="t">DC to Daylight</a></p> <p style="margin:0;"></p> </div> </div><div style="clear:both;"></div> <div style="font-size: 90%;">Tags: incandescent oscillator, total harmonic distortion, derek, HP200a, dc to daylight, THD, audio oscillator, wien bridge oscillator</div> https://community.element14.com/challenges-projects/element14-presents/dc-to-daylight/w/documents/27646/making-a-wien-bridge-light-bulb-oscillator----dc-to-daylight-12/revision/2Mon, 06 Feb 2023 13:53:58 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:bf9b08de-1b7f-4a0d-9546-d48da0dfbf8ctariq.ahmadhttps://community.element14.com/challenges-projects/element14-presents/dc-to-daylight/w/documents/27646/making-a-wien-bridge-light-bulb-oscillator----dc-to-daylight-12#commentsRevision 2 posted to Documents by tariq.ahmad on 2/6/2023 1:53:58 PM<br /> <p><a href="https://www.youtube.com/watch?v=cel8PFn088Q">www.youtube.com/watch</a></p> <p style="background-color:#e9f6fc;border:1px solid #b8d7e5;margin:0;max-width:744px;padding:8px;">In the early days of electronics, accurate and high performance test equipment was physically large and unruly.
