James Akers<p>In my researching for coating tubes I have been collecting a bunch of literature around the matter. This Russian book, the "Biblioteka Svetotekhnika" printed in 1990, (originally 1977) had an interesting method around checking the thickness of the phosphor coating on the inside of the tube.</p><p>As seen in figure 9 here, it involves a light source in a box that your test tube goes into and a photocell sits at the top for a resistance reading of the light going through the phosphor coating of tube- a quick way to measure thickness.</p><p>They are using an incandescent bulb on isolation transformer and variac along with a Selenium photocell. I will be using a neon filled tube that I might dim and a CDS cell adhered to the top hole in my PETG box.</p><p>Thanks 3D printer.... I guess I could have made this in cardboard... but the printer makes it too easy.</p><p><a href="https://expressional.social/tags/tools" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>tools</span></a> <a href="https://expressional.social/tags/recreation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>recreation</span></a> <a href="https://expressional.social/tags/specialtools" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>specialtools</span></a> <a href="https://expressional.social/tags/tubecoating" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>tubecoating</span></a> <a href="https://expressional.social/tags/neon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>neon</span></a> <a href="https://expressional.social/tags/nerd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>nerd</span></a> <a href="https://expressional.social/tags/craft" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>craft</span></a> <a href="https://expressional.social/tags/customcolors" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>customcolors</span></a> <a href="https://expressional.social/tags/fluorescent" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>fluorescent</span></a> <a href="https://expressional.social/tags/artist" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>artist</span></a> <a href="https://expressional.social/tags/3dprinting" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>3dprinting</span></a> <a href="https://expressional.social/tags/oldbook" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>oldbook</span></a> <a href="https://expressional.social/tags/brooklyn" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>brooklyn</span></a> <a href="https://expressional.social/tags/light" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>light</span></a> <a href="https://expressional.social/tags/nyc" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>nyc</span></a></p>
MDMRNIn the midst of my books on my shelf lies this Newbery Award winning classic, "A Wrinkle In Time."<br> <br> When I was in elementary school, I got this copy of the book. Even then, it was an old copy and it was well used after that. I believe I read this book annually until I was in college. I've read it a few times since, including a read through to my children back in 2020/2021.<br> <br> I still love it.<br> <br> What older books from your childhood, if any, do you still have on your shelf? Have you re-read them? <br> <br> Let me know in the comments!<br> <br> <a href="https://pixelfed.social/discover/tags/Books?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#Books</a> <a href="https://pixelfed.social/discover/tags/Bookstagrammer?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#Bookstagrammer</a> <a href="https://pixelfed.social/discover/tags/AWrinkleInTime?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#AWrinkleInTime</a> <a href="https://pixelfed.social/discover/tags/MadelineLEngle?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#MadelineLEngle</a> <a href="https://pixelfed.social/discover/tags/NewberyAward?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#NewberyAward</a> <a href="https://pixelfed.social/discover/tags/OldBook?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#OldBook</a> <a href="https://pixelfed.social/discover/tags/OldBooks?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#OldBooks</a> <a href="https://pixelfed.social/discover/tags/Photo?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#Photo</a> <a href="https://pixelfed.social/discover/tags/Bookstagram?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#Bookstagram</a> <a href="https://pixelfed.social/discover/tags/Bookstodon?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#Bookstodon</a>
