Kris\Slyka<p>ok, after a lot of fucking around and not nearly enough finding out I've finally got my DIY vidicon camera making images again! And they're… better?! They're definitely a <em>lot</em> sharper, but with increased bandwidth and sensitivity also comes increased noise!</p><p>Luckily the noise does not seem to stem from the preamp itself, which is nice, but only shows up once the high voltage is turned on, so it's probably mostly from the pretty noisy switching high voltage supply and the general… well… lack of proper grounding and power supply stability and shielding and all of that. There is more than a volt of ripple on the 300V rail which probably isn't good…</p><p>First image is straight from the camera, second one is the average of multiple exposures.</p><p><a href="https://pawb.fun/tags/Vidicam" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Vidicam</span></a> <a href="https://pawb.fun/tags/electronics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>electronics</span></a> <a href="https://pawb.fun/tags/Photography" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Photography</span></a></p>
