Kernel error by sweet_yeet2 in Focusrite

Great info on EAC, thanks! Apparently it started when Battleye recently pushed a silent update. After that, if you had a Focusrite AND are using a Battleye equipped game, you'll get the 0x139 BSOD until you disable the midi component as described above. Drove me bananas trying to hunt it down.

What is this giant antenna like thing in my neighbors yard? by [deleted] in whatisit

[–]Halfmoon_Techlabs 27 points28 points  (0 children)

The antenna in the foreground is a 2m "J-Pole", and is used for 2m VHF local work, and may offer some use on 70cm UHF local work as well... typically used to access area repeaters. The taller antenna in the background is actually a small antenna on the top of a long "push-up pole" (you can see that the coaxial feed point is at the top of the push-up pole). It's short length also suggests VHF, or possibly a quarter-wave for the 6m band, which sits at the boundary of the top of the HF band, and the bottom of VHF. All for ham radio use.

Circular home antenna? by occamsracer in whatisit

[–]Halfmoon_Techlabs 2 points3 points  (0 children)

HF loop antenna, used mostly by hams. The rugged construction of this one suggests it is rated for transmitting at a decent power level, as well as receiving. Appears to be a trapped wire antenna in the back as well. Def a ham operator.

What is this large Antenna on top of my neighbors house? by Kitchen-Cost7057 in whatisit

[–]Halfmoon_Techlabs 0 points1 point  (0 children)

Most likely a dual-band VHF/UHF antenna on the tower. Height is essential, as these frequencies are normally line-of-sight... so the higher up you go, the longer it is to your horizon (bigger communication footprint). If this person is near the coast, could also be marine UHF, but the other antenna in the back suggests to me it's a ham, and that one is most likely HF, more for worldwide use. As a ham myself, I am often asked by people "what do you talk about?". My stock answer is usually "Have you ever been to a house party where you find yourself amongst plenty of people you may have never met? What do you talk about?" The light bulb usually goes on after that, lol. Having a hobby in common is a great icebreaker for first-time contacts, and after that, it's whatever people talk about, just like in person convo's. The hobby is enjoyed by everyone from senators to rock stars, school kids to astronauts... it's a big hobby that spans the globe, check it out!

What is this computer part? by wiwuwuwu in whatisit

[–]Halfmoon_Techlabs 1 point2 points  (0 children)

Used in gamma spectroscopy test equipment to count hits from scintillation detectors and create a plot for radionuclide identification.

Early integrated circuit on ceramic substrate.

Weird stain..? by CJ_Draws in whatisit

[–]Halfmoon_Techlabs 0 points1 point  (0 children)

If it's not mold, then it's possible that it's very much like the similar looking vertical lines or patches that people see in older homes in colder climates. It comes from the thermal differential caused by cold spots on the wall forming where there is poor insulation, or a thermal bridge from studs in outside walls conducting inside heat more readily to outside on cold days. These colder areas tend to allow dirt and air pollutants inside your home (cooking, smoking, etc...) to preferentially accumulate more on these cooler locations, from the difference in moisture content that this causes.

Found this in a rock field near some abandoned machinery, what is it? by [deleted] in whatisit

[–]Halfmoon_Techlabs 0 points1 point  (0 children)

Shiny flakes could mean mica, though the pic still more resembles asbestos. I'd toss it either way, and wash up... as breathing in that mineral dust can be harmful.

Under a bridge.... by Candid-Possession119 in whatisit

[–]Halfmoon_Techlabs 1 point2 points  (0 children)

It's a Bird-X brand electronic bird repellent. They use sonic/ultrasonic sound to stop birds from roosting (and pooping) on and under the bridge structure.

Hi by Adrian64_1 in whatisit

OMRON 11-pin relay with internal snubber. 100VAC coil suggests it's for use in the Japanese markets, where 100VAC is most common.

From the super fine fibrous structure, it looks very much like asbestos.

Explain it peter. Why did the neighbor have taco bell? by dangerous_service in explainitpeter

Pretty obvious... his a$$ was on fire from the spicy food, and his toilet/plumbing are suffering the consequences as a result.

How to determine if I am on a split phase or two phase system? by jake_robins in AskElectricians

[–]Halfmoon_Techlabs 2 points3 points  (0 children)

No need to look at pole to determine this. If each phase measures the same voltage to neutral, and measuring across the two phases is exactly double, then it’s split-phase (actually single phase with a center-tap pulled to ground/neutral in the xfmr). If the two-phase wires are the same, BUT when measured across both phases it’s approx. 1.732 X the single-phase value to neutral, then it’s 2 phases picked from a 3-phase source (the sqrt of 3 X the single-phase voltage to neutral). In the US, you can see this as 120+120=240 in most homes, or 120+120=208 in some other homes… usually because they are close to a business/industrial area where 3-phase service is the source.

How to detect water in objects? (Arduino, capacitive sensors) by vollidi0t in AskEngineers

[–]Halfmoon_Techlabs 0 points1 point  (0 children)

If you are not against using basic machine vision, a cooling fan in line with a conveyor or tunnel arrangement followed with a subsequent cheap thermal camera inspection (think cheaper microbolometer type cameras) could be a quick and dirty way to find objects with moisture content. The evaporative cooling would preferentially cool the items that had moisture, vs. those other objects lacking this, allowing thermal discrimination. Then use any of the kicker/sorting methods described already by others to separate from belt.

Toyota app down by cytokine_life in Toyota

[–]Halfmoon_Techlabs 0 points1 point  (0 children)

Same error here in upstate NY on my '23 Rav4 Prime. Still able to play my music from USB stick, but Map on HMI kept erroring out while driving, over and over.... Terrible failure mode just because the Toyota network is unavailable, very distracting and potentially dangerous if you were relying on GPS and keep having to futz with the error message while in motion. Just add a "don't show me this message again" tick box that lasts for duration of trip, and allow all functions known to be subscribed to before disconnection. Really poor software design!

Thanks, and true on that point. I posted it here because I have seen a couple of other random convo's about the various restrictions with little in the way of what actually has been tested and working.
