Meteor Shower Season Heats Up as Orionids and Taurids Activate

Earth is set to pass through a series of dusty clouds of space debris from Halley’s Comet and others that promise to light up night skies.

August’s Perseid meteor shower may be the most well known of the year, but it’s the last quarter of the year that brings the most shooting-star and fireball action to night skies.

As of this week, both the Orionid and Southern Taurid meteor showers are active. While the Orionids aren’t set to peak until around Oct. 20, they still add some shooting stars to each evening right away. The Taurids, on the other hand, don’t have a very defined peak and are forecast to be visible at a rate of around two per hour over the next several weeks.

Adding to the celestial drama is the Taurids’ reputation for delivering a number of bright fireballs streaking through the sky.

«In 2022, the Earth passed through a swarm of Taurid fireballs,» writes Bob Lunsford for the American Meteor Society. «This year we are further from this swarm but will still encounter some fireball activity.»

The Taurids can be traced to debris from the comet 2P/Encke, while the Orionids are connected to the leavings of the famed Halley’s Comet, which visits the inner solar system only about every 75 years. The celebrity snowball won’t be back until 2061.

Two distinct clouds from Halley’s Comet are responsible for both the Orionids each October and the Eta Aquariids meteor shower in May.

How to see the celestial show

When the Orionids peak between Oct 20 and 22, the conditions should be nearly perfect, especially with the moonless sky on the morning of the 22nd in the hours just before dawn. Most nights, the area near the constellation of Orion the Hunter where the Orionids appear to radiate from will be highest in the sky around 2 a.m. But it may be possible to see the meteors anytime between midnight and dawn.

The Orionids are known for zipping through the sky at relatively high speed and often leaving long trains that can linger for a second or two.

During those peak mornings, the number of Orionid meteors will suddenly increase to between 10 and 20 per hour, but sometimes Earth passes through a particularly dense pocket of debris and those rates shoot up to 50 to 70, rivaling the Perseids.

While it’s worth marking the Orionids’ peak on your calendar, you might be able to catch a handful of meteors and a fireball on any given night over the next several weeks.

If you have at least an hour free on a night with clear skies and a location away from light pollution, all you need to do is find an area with a broad view of the night sky. Allow at least 15 minutes for your eyes to adjust to the darkness and then just relax, lie back and watch.

You’ll hear seasoned skywatchers talking about orienting yourself to face the radiant of a particular meteor shower. The radiant is the section of the sky from which certain meteors will appear to radiate outward. Meteor showers are usually named for a constellation within that radiant, so the Orionids are named for Orion.

If you can locate Orion in the sky and orient yourself in that direction, it might boost your viewing experience slightly. But the reality is that most amateurs won’t notice a difference. It’s far more important to have dark skies away from light pollution and the widest view of the sky possible. While meteors might originate from a certain radiant, they go all over the sky from that point, so it really doesn’t matter much which way you face.

Plus, there are more than Orionids up there on most nights. There are also the aforementioned Taurids, smaller showers like the Anthelion and even sporadic meteors that aren’t part of defined showers.

So just plan for at least an hour outside, preferably between midnight and dawn, for the best chance to make it through lulls in activity and spotting a few meteors. Be sure to bring all you need to be comfortable that long: Blankets, snacks and drinks are a good idea. Good luck!

TMR vs. Hall Effect Controllers: Battle of the Magnetic Sensing Tech

The magic of magnets tucked into your joysticks can put an end to drift. But which technology is superior?

Competitive gamers look for every advantage they can get, and that drive has spawned some of the zaniest gaming peripherals under the sun. There are plenty of hardware components that actually offer meaningful edges when implemented properly. Hall effect and TMR (tunnel magnetoresistance or tunneling magnetoresistance) sensors are two such technologies. Hall effect sensors have found their way into a wide variety of devices, including keyboards and gaming controllers, including some of our favorites like the GameSir Super Nova.

More recently, TMR sensors have started to appear in these devices as well. Is it a better technology for gaming? With multiple options vying for your lunch money, it’s worth understanding the differences to decide which is more worthy of living inside your next game controller or keyboard.

How Hall effect joysticks work

We’ve previously broken down the difference between Hall effect tech and traditional potentiometers in controller joysticks, but here’s a quick rundown on how Hall effect sensors work. A Hall effect joystick moves a magnet over a sensor circuit, and the magnetic field affects the circuit’s voltage. The sensor in the circuit measures these voltage shifts and maps them to controller inputs. Element14 has a lovely visual explanation of this effect here.

The advantage this tech has over potentiometer-based joysticks used in controllers for decades is that the magnet and sensor don’t need to make physical contact. There’s no rubbing action to slowly wear away and degrade the sensor. So, in theory, Hall effect joysticks should remain accurate for the long haul.

How TMR joysticks work

While TMR works differently, it’s a similar concept to Hall effect devices. When you move a TMR joystick, it moves a magnet in the vicinity of the sensor. So far, it’s the same, right? Except with TMR, this shifting magnetic field changes the resistance in the sensor instead of the voltage.

There’s a useful demonstration of a sensor in action here. Just like Hall effect joysticks, TMR joysticks don’t rely on physical contact to register inputs and therefore won’t suffer the wear and drift that affects potentiometer-based joysticks.

Which is better, Hall effect or TMR?

There’s no hard and fast answer to which technology is better. After all, the actual implementation of the technology and the hardware it’s built into can be just as important, if not more so. Both technologies can provide accurate sensing, and neither requires physical contact with the sensing chip, so both can be used for precise controls that won’t encounter stick drift. That said, there are some potential advantages to TMR.

According to Coto Technology, who, in fairness, make TMR sensors, they can be more sensitive, allowing for either greater precision or the use of smaller magnets. Since the Hall effect is subtler, it relies on amplification and ultimately requires extra power. While power requirements vary from sensor to sensor, GameSir claims its TMR joysticks use about one-tenth the power of mainstream Hall effect joysticks. Cherry is another brand highlighting the lower power consumption of TMR sensors, albeit in the brand’s keyboard switches.

The greater precision is an opportunity for TMR joysticks to come out ahead, but that will depend more on the controller itself than the technology. Strange response curves, a big dead zone (which shouldn’t be needed), or low polling rates could prevent a perfectly good TMR sensor from beating a comparable Hall effect sensor in a better optimized controller.

The power savings will likely be the advantage most of us really feel. While it won’t matter for wired controllers, power savings can go a long way for wireless ones. Take the Razer Wolverine V3 Pro, for instance, a Hall effect controller offering 20 hours of battery life from a 4.5-watt-hour battery with support for a 1,000Hz polling rate on a wireless connection. Razer also offers the Wolverine V3 Pro 8K PC, a near-identical controller with the same battery offering TMR sensors. They claim the TMR version can go for 36 hours on a charge, though that’s presumably before cranking it up to an 8,000Hz polling rate — something Razer possibly left off the Hall effect model because of power usage.

The disadvantage of the TMR sensor would be its cost, but it appears that it’s negligible when factored into the entire price of a controller. Both versions of the aforementioned Razer controller are $199. Both 8BitDo and GameSir have managed to stick them into reasonably priced controllers like the 8BitDo Ultimate 2, GameSir G7 Pro and GameSir Cyclone 2.

So which wins?

It seems TMR joysticks have all the advantages of Hall effect joysticks and then some, bringing better power efficiency that can help in wireless applications. The one big downside might be price, but from what we’ve seen right now, that doesn’t seem to be much of an issue. You can even find both technologies in controllers that cost less than some potentiometer models, like the Xbox Elite Series 2 controller.

Caveats to consider

For all the hype, neither Hall effect nor TMR joysticks are perfect. One of their key selling points is that they won’t experience stick drift, but there are still elements of the joystick that can wear down. The ring around the joystick can lose its smoothness. The stick material can wear down (ever tried to use a controller with the rubber worn off its joystick? It’s not pleasant). The linkages that hold the joystick upright and the springs that keep it stiff can loosen, degrade and fill with dust. All of these can impact the continued use of the joystick, even if the Hall effect or TMR sensor itself is in perfect operating order.

So you might not get stick drift from a bad sensor, but you could get stick drift from a stick that simply doesn’t return to its original resting position. That’s when having a controller that’s serviceable or has swappable parts, like the PDP Victrix Pro BFG, could matter just as much as having one with Hall effect or TMR joysticks.
