GeekMomProjects<p>I'm belatedly getting around to showing off this **GORGEOUS** crochet hat the uber talented <span class="h-card" translate="no"><a href="https://mstdn.social/@alpenglow" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>alpenglow</span></a></span> made for me. She integrated a pebble light string and <a href="https://mastodon.social/tags/pixelblaze" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>pixelblaze</span></a> controller. It's all powered by a flat top 18650 with a clever charge/discharge circuit designed by <span class="h-card" translate="no"><a href="https://mastodon.social/@clomads" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>clomads</span></a></span> that snaps just over the positive terminal and minimizes the power circuitry. I'll be seeking out cold places just to wear it!</p>
Jason Coon<p>Finally revisiting "Fibonacci256 Expanding"! I found a few working LED PCBs in my stash, finished the <a href="https://leds.social/tags/lasercut" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>lasercut</span></a> acrylic enclosure, got it working with <a href="https://leds.social/tags/PixelBlaze" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>PixelBlaze</span></a> by <span class="h-card" translate="no"><a href="https://leds.social/@wizard" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>wizard</span></a></span>, submitted for approval on Lectronz, and up for sale soon!<br><a href="https://www.evilgeniuslabs.org/fibonacci256-expanding-pixelblaze" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">evilgeniuslabs.org/fibonacci25</span><span class="invisible">6-expanding-pixelblaze</span></a></p>
Jason Coon<p>I realize that I skipped a step. If, instead of pixels being only off or on, you use a wave function for brightness (value) where the period of the wave is each pixels' radius, you get a much smoother pattern. The <a href="https://leds.social/tags/Pixelblaze" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Pixelblaze</span></a> code is short and relatively simple: <a href="https://gist.github.com/jasoncoon/dbda5f390872cec21ec2ba875ff5b14f" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">gist.github.com/jasoncoon/dbda</span><span class="invisible">5f390872cec21ec2ba875ff5b14f</span></a><br>Get your own Fibonacci256 here: <a href="https://lectronz.com/products/fibonacci256-hdr-166mm" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">lectronz.com/products/fibonacc</span><span class="invisible">i256-hdr-166mm</span></a></p>
Jason Coon<p>Now if you take all of that, use a pattern (ColorWaves) by an LED guru like Mark Kriegsman, port it to <a href="https://leds.social/tags/Pixelblaze" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Pixelblaze</span></a> with the help of <span class="h-card" translate="no"><a href="https://leds.social/@wizard" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>wizard</span></a></span>, use long slow smooth wave functions for hue, saturation and value, and use color palettes instead of just always shouting rainbows, you get a pattern that slowly shifts and ~never repeats.<br><a href="https://lectronz.com/products/fibonacci256-hdr-166mm" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">lectronz.com/products/fibonacc</span><span class="invisible">i256-hdr-166mm</span></a></p>

Kernel Bob<p><span class="h-card" translate="no"><a href="https://leds.social/@jasoncoon" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>jasoncoon</span></a></span> I'm finally getting into writing shaders for my PixelBlaze/Evil Genius Labs LED cube. I call this one Bubble Phi. It uses the R₂ low discrepancy sequence to pick the colors, thanks to <span class="h-card" translate="no"><a href="https://mastodon.gamedev.place/@mbr" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>mbr</span></a></span> for showing it to me.

gallaugher<p>Am thinking for starters I’ll just laser cut a wooden circle the circumference of the <a href="https://mastodon.world/tags/LED" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>LED</span></a> strip, wrap it around the end, and try some sort of paper cover or other slightly rigid diffuser a bit larger than the circle. This is just under paper at home office with <a href="https://mastodon.world/tags/pixelblaze" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>pixelblaze</span></a> shuffle. We’re gonna have fun with this! LMK your suggestions for lights to buy and projects to try!</p>
GeekMomProjects<p>Just finished sewing a new sling bag with a 32x18 LED matrix inside the pocket flap. The pocket flap snaps off so the matrix can be used in other designs. The <a href="https://mastodon.social/tags/Pixelblaze" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Pixelblaze</span></a> controller and battery fit nicely inside the front pocket</p>
Jason Coon<p>Finished tweaking the map for this cluster of seven x 1" Fibonacci128. Driving it with a <a href="https://leds.social/tags/PixelBlaze" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>PixelBlaze</span></a> by <span class="h-card" translate="no"><a href="https://leds.social/@wizard" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>wizard</span></a></span><br>Get your own 1" Fibonacci128: <a href="https://lectronz.com/products/inch-fibonacci128" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">lectronz.com/products/inch-fib</span><span class="invisible">onacci128</span></a></p>
GeekMomProjects<p>The diffusers on the new LED polyhedron (dihedral hexacontahedron, right) looked so much better than the first build that I had to print new ones for the truncated icosahedron (left). I also synced up the patterns on both builds (with <a href="https://mastodon.social/tags/pixelblaze" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>pixelblaze</span></a>) and will be sitting here staring at them for the rest of the day.</p>
ewhac<p>I just got one of these gadgets today, and the more I think about it, the more impressed I am.</p><p>Not only does it make LED strands light up in pretty colors, not only can it accept nearly arbitrary patterns, but it also hosts a *Web UI,* on which you can edit the LED patterns *live!*</p><p><a href="https://mastodon.social/tags/Pixelblaze" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Pixelblaze</span></a></p><p><a href="https://electromage.com/pixelblaze" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="">electromage.com/pixelblaze</span><span class="invisible"></span></a></p>
GeekMomProjects<p>The LED deltoidal hexacontahedron is complete! 60 identical PCB sides covered with 3D printed diffusers. Two <a href="https://mastodon.social/tags/Pixelblaze" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Pixelblaze</span></a> controllers work in sync to provide a fast frame rate for patterns on the 1200 LEDs.</p>
Jason Coon<p>Here's a demonstration of a sound-reactive pattern via the <a href="https://leds.social/tags/PixelBlaze" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>PixelBlaze</span></a> by <span class="h-card" translate="no"><a href="https://leds.social/@wizard" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>wizard</span></a></span> playing on one Fibonacci512 surrounded by eight Fibonacci256.<br>DM me if interested.

Jason Coon<p>I currently have one Fibonacci512 PixelBlaze available for sale, DM me if interested.

Alpenglow Industries<p>Lately I’ve been working with <a href="https://mstdn.social/tags/Pixelblaze" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Pixelblaze</span></a> Picos and pebble LEDs strands of various types, and I made some helper boards to make wiring them up easier! Here’s a video about it, explaining how to use them to create a continuous LED chain with tentacles that drop down. I think these would be great for <a href="https://mstdn.social/tags/cosplay" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>cosplay</span></a> and making a skirt. I’ve been working on these in collaboration with <span class="h-card" translate="no"><a href="https://leds.social/@wizard" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>wizard</span></a></span> so they’ll be coming soon to the Alpenglow website and prob the Electromage site too! <a href="https://youtu.be/ITolLfaTvGk?feature=shared" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">youtu.be/ITolLfaTvGk?feature=s</span><span class="invisible">hared</span></a></p>
Jason Coon<p>Surprised and delighted to randomly see my LED Mapper tool used, along with <a href="https://leds.social/tags/PixelBlaze" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>PixelBlaze</span></a> by <span class="h-card" translate="no"><a href="https://leds.social/@wizard" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>wizard</span></a></span>, in this absolutely brilliant LED mask build by <span class="h-card" translate="no"><a href="https://mastodon.social/@Seanhodgins" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>Seanhodgins</span></a></span>!<br>Video: <a href="https://www.youtube.com/watch?v=Shy7WcQO15A" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">youtube.com/watch?v=Shy7WcQO15</span><span class="invisible">A</span></a><br>LED Mapper: <a href="https://jasoncoon.github.io/led-mapper" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="">jasoncoon.github.io/led-mapper</span><span class="invisible"></span></a></p>
GeekMomProjects<p>Finished V2 of the truncated icosahedron, and I'm very happy with how it turned out. The sides are 32 hexagonal and pentagonal PCBs, joined by 3D printed corner connectors and covered with 3D printed diffusers. The pixels are mapped and it's running 3D animation patterns on a <a href="https://mastodon.social/tags/pixelblaze" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>pixelblaze</span></a>.</p>
Ben K<p>Quick test with a <a href="https://leds.social/tags/PixelBlaze" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>PixelBlaze</span></a> and some DIY addressable LED paracord. Encasing the 2.7mm LED strand in the paracord took a bit of work but makes it looks nice.</p><p>First time using one of these and so far it's much nicer than some of the other things I've used. Looking forward to playing around with the accelerometer and live coding.</p><p><a href="https://leds.social/tags/LEDs" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>LEDs</span></a></p>
Jason Coon<p>I should really revisit this project soon, using a <a href="https://leds.social/tags/PixelBlaze" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>PixelBlaze</span></a> V3 Pico with 6 Axis sensor by <span class="h-card" translate="no"><a href="https://leds.social/@wizard" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>wizard</span></a></span>, and inductive charging.
