Søren Kjærsgaard<p>In January, I bought two 10V references, based on LM399. I was a bit skeptical on the design, following Marco Reps on YouTube does that to you 😂, but a teardown revealed quality components (Vishay precision resistors) and a decent circuitry and PCB layout.<br>I measured the standard deviation on the 10V output, using my 3458A, and I’ve done so monthly-ish ever since, leaving them powered all the time. <br>In March I added two more, unit 3 and 4.<br>Result so far: unit 1,2,3 are converging towards 1uV SDEV, unit 4 however (separate curve), started out sky-high, but it has now joined the ppm club 🤷🏼♂️😳<br>Someone mind telling me what’s going on? I mean, it’s wellknown that the noise drops over time, but why? What physical/chemical factors comes at play, causing this behavior? <br><a href="https://techhub.social/tags/voltnuts" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>voltnuts</span></a> <a href="https://techhub.social/tags/ppmgeek" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ppmgeek</span></a> <a href="https://techhub.social/tags/electronicsengineering" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>electronicsengineering</span></a> <a href="https://techhub.social/tags/testandmeasurement" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>testandmeasurement</span></a></p>
Søren Kjærsgaard<p>I needed a bit of distraction, so why not go ahead with the bi-yearly gear power-up 🙂</p><p>So today is the day where you power up your precious instruments you don’t use too often, thereby preserving the capacitors in power supplies, analogue circuitry, etc. </p><p>It doesn’t take long, an hour will do it 🙂⏰</p><p><a href="https://techhub.social/tags/electronicsengineering" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>electronicsengineering</span></a> <a href="https://techhub.social/tags/rfengineer" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>rfengineer</span></a> <a href="https://techhub.social/tags/hamradio" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>hamradio</span></a> <a href="https://techhub.social/tags/hamr" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>hamr</span></a> <a href="https://techhub.social/tags/testandmeasurement" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>testandmeasurement</span></a></p>
Søren Kjærsgaard<p>Powering up a blue laser diode to 500mW 🙂<br>Note how it acts like a poor LED until 150mA, at which point the laser process fires 🔥 </p><p>The 505B is an accurate, adjustable current source which allows for external modulation input. </p><p>It’s designed for low-noise (<1.5uA RMS) and it has a photo diode input, so with a calibrated light sensor, you can achieve constant power regulation.</p><p>Last but not least: it’s designed for maximum safety with two interlock circuits, one with a physical key.<br>Its internal design has a complex redundant output circuit, which ensures that the laser will NEVER illuminate unintended and it will NEVER exceed the chosen power setting. </p><p>A fancy current source indeed, a laboratory grade instrument 🙂</p><p>This video was shot wearing the appropriate safety glasses, be VERY CAREFUL when experimenting with lasers. Even a short duration reflection at this power level WILL damage your vision 🚨‼️</p><p><a href="https://techhub.social/tags/electronicsengineering" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>electronicsengineering</span></a> <a href="https://techhub.social/tags/electronics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>electronics</span></a> <a href="https://techhub.social/tags/physics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>physics</span></a> <a href="https://techhub.social/tags/stem" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>stem</span></a> <a href="https://techhub.social/tags/laserfun" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>laserfun</span></a> <a href="https://techhub.social/tags/funwithlasers" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>funwithlasers</span></a> <a href="https://techhub.social/tags/ee" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ee</span></a> <a href="https://techhub.social/tags/testandmeasurement" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>testandmeasurement</span></a></p>
Søren Kjærsgaard<p>Adding parallel circuit allows for the Lambda Diode to oscillate at a frequency determined by the LC resonance frequency. The result is an absolutely beautiful sine wave 🤩</p><p>Note how the oscillation starts, once the supply voltage crosses where the current starts to decrease, ending up at the ‘negative resistance’ portion of its characteristic. </p><p>This is likely the easiest and most clean oscillator I ever built 😃 I wonder if you can use a crystal or crystal f it would get damaged from the drive level 🤔<br>Maybe one of those vintage ones.. </p><p><span class="h-card" translate="no"><a href="https://mastodon.radio/@va3db" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>va3db</span></a></span></p><p><a href="https://techhub.social/tags/signalsaturday" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>signalsaturday</span></a> <a href="https://techhub.social/tags/electronics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>electronics</span></a> <a href="https://techhub.social/tags/rfengineer" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>rfengineer</span></a> <a href="https://techhub.social/tags/testandmeasurement" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>testandmeasurement</span></a> <a href="https://techhub.social/tags/hamr" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>hamr</span></a> <a href="https://techhub.social/tags/hamradio" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>hamradio</span></a> <a href="https://techhub.social/tags/electronicsengineering" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>electronicsengineering</span></a> <a href="https://techhub.social/tags/siglent" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>siglent</span></a></p>
Søren Kjærsgaard<p>So when you have a bunch of jellybean JFETs (2N5457), time to burn, and a handful of 1uF bipolar capacitors… <br>What to do.. 🤷🏼♂️🤓</p><p>I decided to build a simple amplifier 😃 Although many find JFETs aren’t quite as intuitive as a regular BJTs, they’re not THAT scary 👻😂 and they’re easily biased, using a megaohm sized resistor from the gate to ground. </p><p>To be able to do some more accurate calculations, I decided to measure the maximum drain current, IDSS, and the negative Gate-Source cut-off (pinch off) voltage, as they can vary significantly even between devices even from the same batch. </p><p>A fun evening in the lab 😃</p><p><a href="https://techhub.social/tags/electronics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>electronics</span></a> <a href="https://techhub.social/tags/rfengineer" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>rfengineer</span></a> <a href="https://techhub.social/tags/electronicsengineering" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>electronicsengineering</span></a> <a href="https://techhub.social/tags/EE" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>EE</span></a> <a href="https://techhub.social/tags/testandmeasurement" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>testandmeasurement</span></a> <a href="https://techhub.social/tags/hamradio" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>hamradio</span></a> <a href="https://techhub.social/tags/hamr" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>hamr</span></a></p>
Søren Kjærsgaard<p>This weekend was special: yesterday the baltic countries: Estonia, Lithuania and Latvia, disconnected from the Russian/Belarus 50Hz power grid, going ‘island mode’, controlling the 50Hz grid frequency themselves. </p><p>After more than a day of different stability tests, this afternoon, just before 13:00 CET, a connection to the European grid was established via Poland, so now the the three countries are in 50Hz sync with Europe. </p><p>I observed a small, undramatic, ‘burp’ in the frequency at the time of the event, and my wall socket is now in full sync with the measurement in Estonia, provided by <a href="https://techhub.social/tags/sympower" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>sympower</span></a>⚡️ 😃👌🏼</p><p><a href="https://techhub.social/tags/gridtech" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>gridtech</span></a> <a href="https://techhub.social/tags/powerdistribution" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>powerdistribution</span></a> <a href="https://techhub.social/tags/electronicsengineering" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>electronicsengineering</span></a> <a href="https://techhub.social/tags/testandmeasurement" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>testandmeasurement</span></a></p>
