skypanther··on Show HN: AstroHelm – Use your phone camera to aim a telescope or telephoto lens
This looks like a nice alternative to PiFinder. No extra hardware required. https://www.pifinder.io/
skypanther··on Unfolder for Mac – A 3D model unfolding tool for creating papercraft
The usecase for Unfolder or Pepkura isn't 3D printing. They're targeted at paper crafting. You print the unfolded file onto paper, cut, fold, and glue to create a 3D object. Something like these samples <https://duckduckgo.com/?t=ffab&q=paper%20craft%20models&ia=i...>
skypanther··on Ask HN: What Are You Working On? (March 2026)
This looks great and I'll probably order a report. A couple of small suggestions. First, the price is very reasonable, but I think you should be more open about what it costs -- maybe on the home page or at least the Order Report page. Second, I think you should tell what areas of the country (world?) that you can provide reports for, again on the main page would be great.
skypanther··on Ask HN: Anyone tried Spotify's AI DJ feature?
I went through the setup where you specify what genre of music you want. It promptly played two top-ten pop songs, which is definitely not what I selected. I've never used it again.
skypanther··on Ask HN: Make cemeteries in cities less offensive by using virtual headstones?
There's a cemetery near me where all the headstones are mounted flat rather than standing up. They even call it a park. Though, you can't go there to use it like you would a park. I really dislike it. I have a couple of relatives buried there. It's impossible to find their graves. In a typical cemetery there are different types of headstones and you can triangulate off certain shaped ones to find your way. I hope my family doesn't bury me there.
skypanther··on Astrophotography Target Planner: Discover Hidden Nebulas
Looks nice, easy to use. Though it wasn't clear at first that I had to select "Discovery Mode" to get anything more than just well-known objects. I still got only 10 objects. I'm surprised that the Equipment section doesn't include diameter and maybe telescope type, also something about camera sensitivity.

skypanther··on Train and Weather Tracker with Raspberry Pi and E-Ink
I used an Inky wHAT display with an old Raspberry Pi B+ to build a weather display that shows live weather pulled from my Ambient Weather station. My project uses Inky's python library. Since the Ambient API doesn't provide forecasts, I pull a daily forecast from the US Weather Service. And I grab the moon phase from Visual Crossing. https://github.com/skypanther/inkywhat

What struck me about the northern lights video was that it showed the Milky Way crossing the sky behind the northern lights. That bright part of the Milky Way is visible in the southern sky but the aurora hugging the horizon like that indicates the viewer is looking north. (Swap directions for the southern hemisphere and the aurora borealis).
skypanther··on Novell – If at first you don't succeed
This brought back some fond memories of writing courseware and teaching NetWare classes at a startup called Logical Operations. We published courses that were an alternative to the official Novell courseware for earning your CNA/CNE. I'm pretty sure I still have my CNE (and MCSE) pin in a box around here somewhere. One of my co-worker's classroom tricks was to establish a network connection via ARCNet over a length of barbed wire.

Logical Operations ran their own Novell network. I recall the server would freeze up periodically. Our admin rigged up a phone line and a relay...call the number and it would power cycle the server. That way, he didn't have to drive into the office to reboot the server at night. <shakes head>

From there, I started teaching DBase courses, which led to programming, which is where my career has been ever since.

skypanther··on Agile development is fading in popularity at large enterprises
Most of my career has been at startups, but I'm at a fairly large enterprise now. Agile is very different here. It's much more rigid. Every team has an agile coach, there are rules that must be followed, there are limits on who can make decisions about certain things, we do every sprint ceremony ever conceived every sprint, all pods must follow the exact same process. There's no flexibility and little acknowledgment of the original Manifesto principles (e.g. people over process). With an implementation like this, I can see why enterprises can fail to gain as much benefit from agile as promised.
skypanther··on All arabica coffee is genetically similar: how can beans taste so different?
I can. I recently roasted up two batches of beans -- some El Salvadoran and some Costa Rican. I roasted both to a Full City (dark) roast level. They were very different. I finished the Costa Rican quickly. It was delicious. I'm struggling to finish the El Salvadoran. I'm terrible at describing flavors, but I'd say it's sour with a tea-like flavor.

There's a lot that goes into the flavor of coffee. The beans themselves of course. Brewing technique has a big influence as well. But also growing conditions (altitude, soil composition, rain/sun mix, etc.), processing (wet vs dry process, fermentation time, etc.), handling and shipping (dry or moist conditions), and probably more I don't know about.

I strongly prefer wet-processed beans (mostly south American varieties) over dry-processed beans (mostly African varieties are processed this way). I haven't tried honey-processed yet.

Green beans stay "fresh" for a really long time, but once roasted beans become stale quickly. I can taste the difference between my roasts a day or two after roasting vs days or weeks later.

skypanther··on Battery-free self-powered sensor harvests magnetic energy
Sadly, I expected that to be the answer. Oh well, I can dream! Thanks for your helpful follow-up.
skypanther··on Battery-free self-powered sensor harvests magnetic energy
I'm sure this is a completely dumb idea. But I want wireless Christmas lights. Individual little clip-on LEDs powered by ambient RF like wifi background, the ambient field from a home's wiring, or an "antenna" that you snake up the trunk of the tree to emit a field. Then you just clip on the lights where you want them. I'm not knowledgeable enough in electronics to know if this is even possible.

skypanther··on The new local data stack: Integrating Dagster, dbt and DuckDB
I only skimmed the article due to its length. But I didn't see anything like a comparison to other toolchains. Like, how is this better/different/worse than Airflow + dbt + Snowflake?
skypanther··on Show HN: Is It Toxic To? – Check if a plant is toxic to your pets
We've had various cats that ate corn, melon, berries and our current crop of cats love our spider plants.
skypanther··on Pythagorean Theorem found on clay tablet 1k years older than Pythagoras (2009)
I took a course at the university of Buffalo in the early 80s about pre-roman examples of Pythagorean geometry in henge monuments and early structures. Basically the class was watching slide shows of the professors vacations across Europe and his photos of old ruins. Then he'd show us a line drawing of the structure and pick out what at times seemed random points that created 3-4-5 triangles. He'd exclaim 'see? They knew about the Pythagorean theorem before Pythagoras!' Our only graded assignment was to write a paper where we "discovered" a similar example. I picked a picture of some random ancient church and "found" the right triangle in it's foundation. I got an A. Definitely just an "observation" no theorum involved.
skypanther··on Black currants were banned in the USA (2017)
Elderberries make great jelly and pie. Unfortunately the birds keep getting mine before they're ripe, it's hard to find them in the wild on public land, and no one grows them commercially around me. So I haven't had either in years.
skypanther··on Speeduino – Arduino based engine management
This has me thinking, are there any similar projects for antique "dumb" cars? I have a 1940 Chevy with a simple distributor, points, timing, etc that all need tweaking now & then. When any of those are out of tune, it runs rough, starts hard, stinks, and so on. I'm not looking for performance, but more efficient and reliable operation would be wonderful.

It would involve a lot more than just an Arduino & some wiring obviously. And a lot of the car's charm is its low-tech originality.

skypanther··on Show HN: Ledonardo, my light painting hardware project
I'd love to see your code. In particular, I'd like to see what you did with "I could just directly assign the data I read from the SD card to the internal buffer of the LED library instance and display it."
skypanther··on Anxiety Looks Different in Men
It describes my symptoms - anger, lashing out, sleep issues. Meds have helped enormously.
skypanther··on How much equity should I get as the first employee?
I got 1.125% which in retrospect was too low. But perhaps the bigger point is to find out or negotiate what it will take to get additional grants. Executives and the founders will likely get additional equity, particularly during funding rounds, the hiring of key roles, etc. You should have a path to getting additional stake too.

skypanther··on The Warlike Origins of ‘Going Dutch’
I've done an awful lot of Dutch oven cooking with my Boy Scout troop. I never once thought the term meant anything other than the cast iron pot.
skypanther··on Ask HN: How often do you work from home?
Every day, for almost 20 years now
skypanther··on A self-driving toy car using end-to-end learning
Perhaps I'm misunderstanding this. But why is a CNN necessary for predicting the turning angle? Seems like OpenCV would be sufficient (assuming sufficient contrast between the line and the floor). Grab image, threshold, find the largest contour around the line, grab its minAreaRect() and from that calculate the angle.

Editing to add -- this is still a cool project. I don't mean to detract from it by pointing out that I think it could be done without the AI piece.
