- Comment on trying to fix a wifi antenna need some help 😅... 2 days ago:
Look up Andrew McNeil on YouTube if you can. He has lots of content and examples. www.youtube.com/channel/UCHqwzhcFOsoFFh33Uy8rAgQ
Without a vector network analyzer with the bandwidth for 2.4/5.8 GHz to tune the signal frequency well, you are poking around in the dark when it comes to real performance.
I’ve built some antennas including a one for WiFi. It made a small difference for awhile, but it turned out there is an error of some kind in the OpenWRT kernel or in the hardware design of the device. It took me a long time to isolate the problem. The router was unable to transition between the 2.4 and 5.8 bands smoothly and was causing problems. I actually get better range and performance by disabling the 2.4 GHz radio entirely. My issue of the bad 2.4 radio is probably unrelated to whatever you’re dealing with, but it is something to think about and maybe test out if you’re trying to improve router performance.

I think you’d find the aberrations problematic for the speeds needed for live action. I think you’d need custom optics to get low enough f-stop and likely some very expensive custom achromatic lens stacks to correct most of the visible wavelengths.
- Comment on Why do arranged marriages persist in many cultures? 6 days ago:
My argument has nothing to do with the sexes like this. Western cultural misogyny is a subtle blind spot overall. I’m willing to bet in many cases both parties are at risk of mistreatment. My point is about autonomy, so there is no difference in that vain, your still signing over autonomy to an arbitrator as a superior controlling entity.
- Comment on Why do arranged marriages persist in many cultures? 6 days ago:
No my actual problem, as described, is autonomy. I’ve yet to see anyone that seems to fully grasp the point I am making. It is a subtle difference.
In writing science fiction for a hobby, I have explored a lot of this recently. I can’t say that I have it all figured out or am some kind of expert. I’ve explored the idea of systems where there are the resources and systems in place to arbitrate without the need for any absolute laws, a place where the guidelines are communicated clearly and a reasonable and just outcome is possible without an arbitrary binary law. With a lot of idealized assumptions glossed over for the sake of conversation, any system that addresses the needs of more people amicably is a better system.
The way marriage is set up presently, it is made for the needs of a majority, but there are many outliers. If you consider this system in abstract, there are 3 people in the marriage; person A, person B and the superior member of the arbitrator as a governing stakeholder. The role of the stakeholder is to uphold a set of complicated laws that may or may not fit the situation of the individuals. In essence, the stakeholder takes away the autonomy of the individual, more or less equally. To our culture, we ignore this loss of autonomy and the neglected outliers. If these types of oversimplified laws were superseded by a system where it is unacceptable to have minority outliers, and the law can flex to the situation in a deterministic, unbiased, and just way, it changes everything about the system and institution of marriage. This is hard to think about in a modern context without a detailed story to explain it by example. The entire system in the present is based on a loss of autonomy. I consider every loss of autonomy to be a form of slavery. That is not to say it is some binary good or bad. It is hyperbole intended to stress a weak spot in present culture. We largely fail to culturally understand how important autonomy is and all the places where we have given it away to others.
I grew up in places where no one had the money to get a divorce, and where it was used as a form of control and abuse. I’ve seen it making people miserable because of stupid choices they made long before their prefrontal cortex was developed. It mostly harms the people at the bottom.
If you trace back in time, marriage has always had an element of misogyny and loss of autonomy. It was far worse in the past. I think that line of evolving change will continue and people of the future will look at the present much as we do the past. Asking myself how that will play out in the distant future, I believe the answer is a much better social awareness of autonomy. This is the trend line that we are on, and improvements have been made, but those will continue into the future. The present is not some benchmark of perfection.

- Comment on Is wine active enough to cultivate and use as a yeast? 1 month ago:
Yes. I’m currently on my 7th and 8th experiments with wild ferments.
I even did something of a fond with my first attempt using a mason jar of fermented blueberries in a 3% salt brine combined with the stock leftover from a 5 pound roast that spent 4 hours on the smoker first and 6 more in a dutch oven. That yielded around 1000ml of hardwood smoky flavored beef stock that originally started with chicken stock and a beer with garlic/onion/pepper etc. The blueberries yielded around 600ml of a savory juice that was like a slightly fruity soy sauce. I reduced that entire mix down to ~600ml and have my first real sauce. It is something like a smokey fruity Worcestershire (garum like fish sauce) sauce.
I’m also working with cherries, and a bunch of variations on a spicy lemon garlic/ginger to explore this area.

- Comment on Whats the Best Breadboard Starter Kit for beginners? 1 month ago:
Ben Eater’s 8 bit breadboard computer project on YT is well explained, and he sells the kits. I forget Ben’s credentials, but he is a professor in CS somewhere. His teaching skill is remarkable.
Some poor sap made a more intuitive set of schematics that also breaks down the kits: github.com/…/8-Bit-Breadboard-Computer
That same guy made some chip labels that some people find useful: github.com/Upcycle-Electronics/ChipLabels
That last one also has a link to a list of databooks on archive dot org. Get the 1996 Motorola CMOS logic databook as your primary starting point reference. That goes into a lot of the details about cross compatibility and exactly what works and what doesn’t.

- Comment on So which budget printer to buy? 1 month ago:
I’m biased to say save and get a Prusa. It is what I did. It is not a printer project. The hardware specs are a misnomer. The continuous investment in the community is the real selling point. I spent more initially, but my Prusa is still worth nearly what I put into it even as a MK3S+ when the 4 is a thing. Everyone knows it will still work, and continue to do so, while parts will always be readily available. No one worries that it is some failed project.
Now if I tried to sell my little modified KP3S Kingroon, that thing is pretty much worthless now even though it works okay most of the time. I spent more on it at $200 than I did on the Prusa at just over 3× as much. I barely used the KP3S, wasted $100 on “upgrades” and it is now all loss. I got it after the Prusa knowing it is a project to screw around with. Spending more can often mean spending less when you consider long term value. That is just my personal opinion. I don’t regret buying the Prusa.
- Comment on Kiddo is loving Pokemon Horizons… 1 month ago:
If you want to improve the surface considerably with an absolute minimum of effort: A single edged chisel Xacto knife blade like #17 is the ideal tool to take off small zits with precision and not risk damaging or making a bigger issue. Note that this is a medium pen size blade, unlike the small pen sized #11 angled blade.
The single bevel allows you to slide the knife over a flat surface using the obtuse bevel side as a fulcrum so that the cutting edge remains just above the surface of the print. The edge will only contact the high spot of the zit without gouging into the print by mistake.
With 3D prints, blade #17 is my most often used tool for basic rough cleanup work :)
- Comment on Kiddo is loving Pokemon Horizons… 1 month ago:
I was not insinuating anything negative. Sorry if that came across. You mentioned painting, and I would not expect handling durability for paint at this scale. That was the message I originally intended. I am a former auto body shop owner and painter. So my perspective is a bit different that most when it comes to finishes. There is nothing wrong with the print. I apologize if my comment came across otherwise.
- Comment on Kiddo is loving Pokemon Horizons… 1 month ago:
All plastics can be sanded and polished. This can yield an excellent result that is indistinguishable from a molded part, especially for ABS/ASA. I have tested with most common materials if you ever need help. Automotive class finishing or an equivalent polishing carry a similar amount of total labor with polishing costing less in overhead.

- Comment on What would be the best way to fix the little stopper switch for one of the motors on my Aquilla? 1 month ago:
If I’m not mistaken, that switch position is part of your calibration and if you print close to the edges on this axis, you are likely to fail. However, you can put anything that will fit in that space and trigger the button on contact in close to the same way. Like a little cut up piece of an old print or anything really. It just needs to be light enough to make a little tape hinge from the top and press in the micro switch button.
When the printer starts it has no idea where 0,0 home is, but it knows the approximate location of the switch. If anything about the switch changes, so will 0,0. This is not super critical or anything, it just has to be close. The switch contact has a relatively large area of uncertainty where it will trigger differently each time. All your print moves are relative to 0,0. So it doesn’t matter if 0,0 moves so long as you have enough margin of error available in your calibration. If you print all the way to the last few millimeters of the build plate, and try to use this hack, that is all that won’t work.
- Comment on What can I use to readd rounded part on print? 2 months ago:
It all really depends on what you are doing and the conditions of the part.
I’m a former auto body shop owner and painter. This kind of thing is what I did all the time, but many techniques are tricky to do in practice.
The flexibility of the material around the repair is important. Like body fillers (bondo) are formulated to have similar properties to steel. There are specific varieties made for different plastics.
If all you need is a temporary fix for tomorrow or a few days from now, masking tape, papier-mâché, etc. You might be able to print a very thin overlay that you can glue over the spot.
In my experience, it sucks, but you’ll likely be better off accepting your mistake now and starting over properly. You would not believe some of the losses I’ve had to take when painting cars because I tried to fix mistakes like this, and even ones I had to start over. Like imagine painting an entire car, completing the job, but deciding you want to do one more clear layer over the hood where there is a slightly dry spot and your spray gun decides it hates you, a seal fails, and a bunch of fluid drips onto the surface ruining the whole job. I’ve had stuff like that happen a ridiculous number of times.
In auto body work, sanding through too much of a surface is very common. You can’t just spray a tiny bit over that surface or ignore it and get away with the issue. It is a big deal. Your problem may not be of this magnitude. It may be fixable, but beware of placing bandaids on bullet holes expecting a full recovery. My rule was to step away and take a break before assessing the situation. Emotional investment clouds one’s best judgement. GL.

Why are you printing this? Surface finish is super important to airflow in a design like this. Printing an overhang layer is not functionally adequate.

- Comment on My creality 4.2.7 board just crapped out. Suggestions for an upgrade? 2 months ago:
You can simply do a USB breakout board and mount anywhere. It is just 4 wires and far less work than wiring a new board. It’s cool if you just want the project. Printed circuit boards are way easier than complex wiring, but for the most part they offer very little advantage over point to point wiring.
If you can hold a hot pencil without touching the tip and glue stuff together with low temp metal just by touching things together, you can solder. Break apart any old switching power supply, break the tiny transformer and unwind it for the thin enameled copper wire. Scrape the enamel off with a razor blade carefully until the whole tip wets with solder. This can attach to any remaining thin traces on the PCB. Scrape the solder mask off the traces until you have bare copper and solder the wires. It is super simple. You can print an extra mount attachment for the breakout board to hold it securely inside, outside, or in a new location entirely.
I do this for all of my routers on my network. I add a USB to serial converter and breakout the UART serial connection so that it is easy for me to flash or monitor the logs from the bootloader through to initialization of the OS. It is not hard to do this.
- Comment on Trying to add text to the bottom of prints and the quality is inconsistent 2 months ago:
There are multiple ways I have solved this. You can add a small chamfer into your design for every edge of the lettering, although this is a pain, or you can adjust the first layer expansion compensation.
Go with the empirical method and measure how far off the first layer is expanded compared to what the measurement should be. Then dial this average figure into your first later expansion compensation.
I know how this works with prusa slicer but I do not know how this terminology translates to Cura if you are using it or something else.
- Comment on What would be a good glue to repair this spatula with that wont he toxic or come undone in a dishwasher? 2 months ago:
That looks like a friction fit. Put it in place and try and crimp the tubing just a little bit. This is a ‘controlled pressing force’ type of operation. Don’t hammer or push too hard too fast. Creative thinking can go a long way in training your inner MacGyver (ancient US TV show reference).
One idea is to use a dining room chair. The leg of a chair can exert a lot of pressing force on a small area. This can work if you lack hand tools, a vise or other methods. Position the tube and lower your weight onto the chair in a controlled manner to alter the geometry enough to securely hold the insert in place.
Two part epoxy would be the only type. The catalyst in most epoxies is probably toxic, there are specialty food safe types, but they cost a fortune. I don’t think this is the solution though. I would go with crimping the tube.
