VisiblAir🛠️ New article!We’ve published our official calibration and certification procedure for VisiblAir sensors.From factory-calibrated PM to outdoor CO₂ calibration (or indoor when it's -20 °C 🥶), it's all explained:🔗 <a href="https://visiblair.com/products/calibration-procedure-and-certification" rel="nofollow noopener" translate="no" target="_blank">https://visiblair.com/products/calibration-procedure-and-certification</a><a href="https://zeroes.ca/tags/AirQuality" class="mention hashtag" rel="nofollow noopener" target="_blank">#AirQuality</a> <a href="https://zeroes.ca/tags/CO2" class="mention hashtag" rel="nofollow noopener" target="_blank">#CO2</a> <a href="https://zeroes.ca/tags/Calibration" class="mention hashtag" rel="nofollow noopener" target="_blank">#Calibration</a> <a href="https://zeroes.ca/tags/RightToRepair" class="mention hashtag" rel="nofollow noopener" target="_blank">#RightToRepair</a> <a href="https://zeroes.ca/tags/OpenHardware" class="mention hashtag" rel="nofollow noopener" target="_blank">#OpenHardware</a>

ChrisRI've just done my second monitor <a href="https://mastodon.scot/tags/calibration" class="mention hashtag" rel="nofollow noopener" target="_blank">#calibration</a> of my MacBookPro with the <a href="https://mastodon.scot/tags/SpyderXPro" class="mention hashtag" rel="nofollow noopener" target="_blank">#SpyderXPro</a>. It has at least got rid of the strange pink-apricot tones on some areas, like the box I'm typing in now. Last time there was no sunshine on my screen, but it was beside the window. This time I turned the screen so no window light at all fell directly on it. Looks better!

Francois DionOne of the idler tires has shipped. I'll be ready when it gets here. I even have a torque test tape, so if they are still out of spec after The new idler rubber replacement, there is a potentiometer on the main board to adjust that.<a href="https://mastodon.online/tags/Technics" class="mention hashtag" rel="nofollow noopener" target="_blank">#Technics</a> <a href="https://mastodon.online/tags/tape" class="mention hashtag" rel="nofollow noopener" target="_blank">#tape</a> <a href="https://mastodon.online/tags/cassette" class="mention hashtag" rel="nofollow noopener" target="_blank">#cassette</a> <a href="https://mastodon.online/tags/calibration" class="mention hashtag" rel="nofollow noopener" target="_blank">#calibration</a> <a href="https://mastodon.online/tags/test" class="mention hashtag" rel="nofollow noopener" target="_blank">#test</a> <a href="https://mastodon.online/tags/repair" class="mention hashtag" rel="nofollow noopener" target="_blank">#repair</a> <a href="https://mastodon.online/tags/diy" class="mention hashtag" rel="nofollow noopener" target="_blank">#diy</a> <a href="https://mastodon.online/tags/Japan" class="mention hashtag" rel="nofollow noopener" target="_blank">#Japan</a> <a href="https://mastodon.online/tags/electronics" class="mention hashtag" rel="nofollow noopener" target="_blank">#electronics</a>

Julien :ve: 🔭:python:Flat calibration frames are used in astrophotography to correct optical "defects" in the imaging train like vignetting and dust on the filters or camera sensor.Multiple images of a uniform light source are taken and combined (averaged) into a master flat frame. Then each frame taken from the target is divided by the normalized intensity of the master flat frame on a pixel per pixel basis. This way, areas that are darker on the master flat frame, like corners when vignetting is present, are made brighter in the calibrated frames and vice-versa.<a href="https://techhub.social/tags/astrophotography" class="mention hashtag" rel="nofollow noopener" target="_blank">#astrophotography</a> <a href="https://techhub.social/tags/calibration" class="mention hashtag" rel="nofollow noopener" target="_blank">#calibration</a>
