Horizontal Cordless Blinds - Fix Broken Spring Cord

Update: This broke a week later. The cartridge won’t hold tension. I suggest rethreading to mod it into a corded blind. There are more than a few tutorials on how to do that out on the interwebs already.

My advice: just don’t. That’s right. I did it. I fixed my Home Depot Cordless Blinds, and I saved $45 doing so, but I wouldn’t recommend doing it again. I got so frustrated and it took so long that I forgot to take instructional pictures.  And I love to take that kind of stuff. If the blinds no longer retract at all, it’s because all three cords have been severed. And if the fact that it happens all the time hasn’t lead you to seek alternative blinds, you might be able to repair them, but I wouldn’t recommend it.

If you’re still determined to do so, you need to:

  1. Pull the blind from the window completely.
  2. Pull out the cassette with springs and spools.
  3. Wind on three new cables onto the spools.
  4. Thread them back through all the other pulleys, obstacles, and slats.
  5. Replace them in the window.

Pulling the blinds from the window when they won’t retract is a pain in your arse. You’ll probably need a helper and a flat-head screwdriver to pry them loose from the bracket. The slats, which are no longer retained by means of a central cord, will try to fall out everywhere. Be careful, our use this opportunity to throw them away completely. You can still do that.

Obtaining cord is a pain. You should grab the 1-2mm kind, but it only comes in 100 yard spools from Amazon. Pull the cassette with razor sharp springs and a baffling spool-and-gear mechanism from underneath the tilt cams by unseating the cams along the whole length of the blinds. Remove the retaining clips (don’t lose them!). Clean out the busted cord from the slats, blind body, and all pulleys. Examine the cassette, and reseat the spring if it’s come loose. Which it will if you play with the mechanism for more than two seconds trying to understand how it works.

 The cassette winding was the part that broke me. Play with the spools and you’ll see there are 4 in total. They counter-rotate. Without any tension on the spools, the spring is fully retracted on one spool and hooks into a cleat on the other. Play with the two thread spools, and you’ll find a slot where you can thread your cord. You’re ready to wind.

Measure out two cords, one at least 18ft long, one 9ft. Make a knot in the center of the long one and a figure 8 on a bight on the short one.  With no tension on the spools, thread the center knot into the spool slot of the outside spool, and slip the bight into the slot of the inside spool. This was the biggest pain: Wind the cords around the spools, keeping your 3 dainty cords consistently on the same side of the spool, around spools within the cassette. I did this by using a blunt tapestry needle and a long and sharp upholstery needle. Avoid tangles, twists, and misthreading. You’ll know your winding properly when you pull both cables and the they both come off at the same rate.  Then they should retract neatly as you let go. I have not tried this, you might be able to thread one side, pull it out, then just slip the other side on and wind it back as you retract the other. Leave enough leader cord out the run it from the cassette, through the body of the blinds, and down through every slat. More is always better. You can trim excess once you’re done. This would have been better with pictures. When it breaks again, I’ll add some. 

Once you have wound the spools, thread the remaining cord onto the tiny pulleys in the cassette. They should all end up on the same side, the front of the main body where the tilt mechanism comes out to attach to the wand. Then pass them through the gaps in the cam supports in the main body, around the wide pulleys and back across the metal corner posts and down the pulleys which lead down to the slats. Thread each of the three cables through every slat and down through the main bottom body. Tie off the cord with a big knot, a button, or some other means of making sure it doesn’t just pull out and unthread all your hard work. Learn from me! With each cable pulled taught and knotted, you’re ready to test.

Even if you do everything right, your test could end in disaster and you might need to start over. Don’t! Just give up! Even if you do it right, it could end up tangled in a month. It could wear out just as fast. Because this design is heinous, prone to failure, and predispositioned to these kinds of shenanigans. Turn back now!

Thought I haven’t done it myself, I would recommend the truly frustrated and also thrifty find a tutorial on how to add cords back to your cordless blinds by forgoing the silly mechanism of the cassette and spring and just attaching a cleat to the wall to hold the tension. If you can make sure the strangulation risks are minimal in your house, it’s a way to fix them without replacing the blinds themselves.

Cyberpunk RED - Rockerboys

Cyberpunk RED miniatures from the Rockerboys faction. Tried to evoke lots of 80's Vaporwave and retro-future Miami Vice with the color choices. The Manager has some of the most effortlessly awesome eyes I've ever done, and the skin and hair on the Guitarist just glows. The assembly was kind of a pain being resin, and you might notice some mistakes if you look too closely as these are tiny tiny minis. But I enjoyed it more than I thought I would. Hopefully, I get to paint more if they keep doing that system.

Nolzur's Marvelous Minis - Palette Cleansers

I call these small projects Palette Cleansers because I paint them in between other big projects like whole army units or big figures and terrain. The Nolzur Minis by Wizkids are cheap, already assembled and primed. They can be frustrating with mold lines, but they are decent enough at 3 ft. These usually come in two sculpts per pack.  I picked one and surplused the other for trades or teaching others how to paint.

Knights of House Caro Mea - The Dark Hand

The Dark Hand, or Manus Tenebrae in High Gothic, is an ancient war machine that traveled the galaxy after The Overgrowth. Eager to reclaim their home world and the forges that wrought these old machines, the knightly house of Caro Mea has joined the Mechanicus expeditionary force. Its pilot keeps the restless machine spirit at the heart of the Dark Hand busy with forest-taming operations. And while the trees of Pholos IV are more hostile than most, recent skirmishes suggest it will be called upon to enter the fray against more heady foes.


After being assembled for 5 years, I finally got the courage to paint this lumbering mech of a Father's Day gift. The under-carriage was a straightforward Leadbelcher with Nuln Oil drybrushed to highlight, and the panels are where I spent most of my time. I'm particularly proud of the blue stripes that give the flat blocks of color subtle depth. In addition, this is my first attempt at decals in some time, and Micro-sol was a miracle-worker at keeping them from being shiny. I used a black Sakura Pigma 005 for writing the name on the chest scroll. The base was mostly an afterthought, and I hope the Necron that was tread underfoot makes a speedy recovery.

Drip Cup for Cast Iron Juicers



Hamilton Beach manual citrus juicers have a handy drip cup that swings out when you put a cup under the juicer, and it swings back into place when you remove your juice. Without this, the dripping juice left in the metal funnel can get all over your bar top, counter, or cutting board. If you have a generic cast iron juicer that doesn't have an attached drip cup, what is an enterprising bartender to do?

Print this thing I added to Thingiverse, of course!

The mechanism uses a rubber band of the right tension to return the cup to its initial position. As you push the cup to the side, guides slide the cup out of the way. The strength of the rubber band should be tuned to be light enough to not push over your juice cup nestled between the loving cast-iron arms of the juicer. When you remove your freshly squeezed juice, the rubber band slides the drip cup back into place. Et voila!

You'll need a rubber band, a conical shot glass (the smaller the better), and an M3 set screw. You will also need a set of hex keys to disassemble the juicer base to get the Shaft sleeve on.

Enjoy your drip-free juicer! Here are some prototype and action shots:

Star Wars Kepi from CyberSeams.com



Ventured into hat making for a Star Wars costume made for my kid. I grabbed the Star Wars Imperial Officer Hat pattern from cyberseams.com. Janet's pattern was amazing! I loved the specific brand recommendations for interfacing, and I also liked that she used actual sewing terms with explanations where a noob like myself might fall down. All my questions were answered by googling when I got stuck.

We have abnormally large heads in this family, so I splashed out with enough material for two. Most of it was available from JoAnn's. My partner sews more than I do, and she helped me make sure I had all the seam allowances and backing correct before I started cutting.

The top and crown was where I struggled the most. It kept bunching up and puckering, and I couldn’t figure out a way to get it to stop. I just lived with it once I fixed the worst spots, and you can’t see it from 10 paces. Especially on black! After finishing the cap, I found that the instructions say to cut relief snips along the seam allowance of the top. Rookie mistake that I should have realized once the puckering started.  Better luck with round two!

Reading Lilith's Brood after Black Lives Matter

DEF CON Theme Screenshot Showing Lilith's Brood as a recommended book

DEF CON 31 had Octavia Butler's Lilith's Brood/Xenogenesis series on it's reading list next to Snow Crash. This recommendation came after the 2020 Black Lives Matter protests which brought antiracist and critical Black history topics to the forefront of public life. Cold War and genetic engineering fears appear throughout without feeling dated, and the three novels remain provocative as they are firmly steeped in the author's American upbringing in Black culture. The old and new contexts brought out the enduring richness of this landmark Black sci-fi author's work. 

Lilith, the series' namesake, takes the reader through her personal salvation at the hands of an alien species. Salvation comes at a price for humanity as a whole, and it brings to mind historical and societal dilemmas of colonizers and colonized, enslavers and enslaved, and generational consequences to descendants of these groups. The aliens are the Oankali, a multi-system species of natural genetic engineers. They are collectors of genetic difference, and they use the genes they collect to improve themselves as they move from star to star. The action is driven by the aliens who claim that humanity has lost the right to earth due to their fierce intelligence combined with hierarchical nature leading to nuclear war. The humans that remain are sterilized and ushered into a breeding program where the Oankali will mix a new species that overcomes this core conflict in human nature.

Elements of Black history are recalled throughout the novels. The Oankali remove tumors from Lilith in an episode that recalls the plight of Henrietta Lacks who provided the initial cells for the first immortalized cell lines called HeLa, and consent is further challenged as it is revealed that children are produced from cell lines of dead or aging humans in the name of saving the species. Children produced from unions and admixture of alien DNA is a central point of later novels. The revulsion in humans that parent admixed children recalls discussions in the African American community of what life must have been like for enslaved people that had children by their enslavers, and it explores generational implications of such couplings for both parents and children. These are obviously informed by the author's personal experience as well as historical accounts of abuse and discrimination against those of African descent in the Americas. Those looking for similar examples that will shock and horrify you should seek out recent popular literature such as Ibram X Kendi's Stamped from the Beginning and the journalistic 1619 Project.

The speculative framework dispenses with some broader cultural discussions without feeling dismissive. The Earth has been colonized, for good or for ill, and the humans have deeply limited choices. Yet this is not a colonial narrative that lauds benevolent overseers for saving benighted natives. Humans never give up on Lilith's original plan to "Run, Hide, and Fight," and the human characters do not romanticize their plight as something fortunate. The concession the humans extract from the Oankali by creating a non-admixed human colony on Mars is explicitly called out for what it is: a glorified reservation. The damage is done to Earth, so it is incumbent for the humans to decide what to do next. The aliens, to their credit, recognize that they make mistakes and commit serial offenses even as they desperately try to integrate humans into their galactic lifecycle in a uniquely alien and much deeper way than historical colonizers have ever admitted or attempted.

After a summer of protests and lockdown reading lists, Butler's adventure on and above a remade Earth shows how deeply human power dynamics of oppressor and oppressed are. While alien pheromones strip consent and poison unions, the books never answer whether Lilith was right when she started the admixture of humans and Oankali. No one ever lets her forget her role as "the Judas goat." This is not a tale of liberation through force or thought.  It is an exploration of consequence and implication when the immovable alien force overtakes a wounded people and runs up against an immovable will to be human. Even as the third book comes to a close, the admixed inhabitants of Lo establish their humanity through perseverance rather than force. Withdrawal of consent, even temporarily, becomes radical when coercion is structural, biological. These have echoes in strikes, riots and protests that rocked the US and the world. We might not have total control of our selves, our emissions, and the external implications of our purchases and relationships. But even a temporary withdrawal of consent can give us power to change the deeper structure of our evolving society.

Skitarii, Mashal, and Tech Priest Dominus

Just finished these 12 minis, all with a similar palette. I only paint right now, so they are probably not playable on the tabletop, lol.


different Dominus is the mini that got me back into painting 5 years ago, so it was refreshing to take another crack at this mini after having learned so much! I have learned a ton about blending and layering since then. The robes are richer, the metals poppier, and I am much more precise.


The marshal was a little disappointing, honestly. I wanted so much more from this mini in terms of greeblies and detail. It ended up being a scaled-up squad leader with a scepter. Literally, their leaders are just taller? Maybe I'll take another crack at his robes and add some trim to liven up the back of the mini. Big sigh.





The squad is where I took all my chances. Again, I painted a squad of these guys about 4 years ago, so the second chance brought many opportunities for improvement. I loved the purple glow, but I still think I can improve my technique. Tips appreciated. I'm not sure I have the heart in me to do a third squad. Going to try some Sicarians and other Ad Mech units instead.


A bit anxious about what to do to make my Next units stand out but mesh with this scheme:

⁠Sicarians can basically echo the black jumpsuit with metallic bits, but I feel like going with that will lack some pop. Maybe leaning into the purple energy on their blades and finding accent pieces to pop with yellow and green?

⁠Pteraxi are the same conundrum, but a wing vein with a green on yellow pattern might be fun. I intend to do the flamer squad. I can really amp up the muzzle burn with purple hues rather than make them glow to match.

⁠Dunecrawler, ironstrider, and robots: I still haven’t done any armor. I don’t want green tanks. I need a good primary color. Was thinking a brown would pull in the base colors, but drab armor is not very 40k, but I’m planning a smooth ivory for my knights. That would tie all the big boys together visually. I’ll have to think on that.

Regardless, no more AdMech for a bit! After painting a big batch like this, I am going to take a break and paint some one-off RPG figs and smaller squads with more painting variety and skill-tests. A batch of Harlequins with their diamond tights and trailing streamers would do me well.
