The projector features a convenient auto-shutoff feature that turns off the lasers in daylight conditions, helping cut down on energy usage. In our latest round of testing, this model blew away the competitors in terms of brightness and coverage area, showering our test room in a massive display of red and green dots. There's one word to describe this simple projector from StarTastic: bright. That said, the low price and wide coverage area of this projector justifies us swapping it into our rankings. Our previous pick for best snowflake projector, the Tangkula LED Snowflake Projector Light, featured a remote which this unit does not, so those wanting more hands-off control should go for the other option. While it wasn't the brightest of the projectors we looked at, it was more than sufficient at creating a lovely display in nighttime light conditions. Lab tests revealed that this projector had an easy set-up, requiring you only fix the heads to their mount (it comes with both a stake for driving into your yard and a flat base for placing atop your patio or deck) and plug in the unit to create a sizable light show. The double-headed design is supported by two ball-and-socket joints that let you customize each projector head's angle individually, giving you total control over the dancing snowflakes it generates. A snowflake projector that'll work in snowy conditions? Look no further than Anerbili's double-headed projector, which features an IP65 rating, meaning it'll withstand exposure to moisture from snowfall as well as dust and other solid particulates in the outdoor air.

This was a generic programming description. The thread now complete, the tool disengages by executing another small arcing motion back to its starting point before withdrawing from the hole. The rotating thread mill then describes one complete circle while simultaneously moving upward (in the Z-axis) by an amount equal to the thread pitch-in our 1/4"-20 example, this would be 0.050", or one complete turn. Regardless, it gives programmers great latitude in their machining approach, the types of material they can machine, and even the size of the threaded hole-a single 20-pitch thread mill can produce any size thread, for instance, provided it has 20 threads per inch and does not exceed the tool’s maximum cutting depth.Ī thread milling operation starts by driving the cutter down the center of a drilled hole at a fairly rapid rate, then using a small arcing motion to move the tool radially into the workpiece until reaching the required diameter. Unlike tapping, which can be performed on practically any machine tool or even by hand, thread milling is only possible on a CNC machining center, Y-axis equipped mill-turn center, or multitasking lathe. Note the term “programming approach” a moment ago. What's different is that a thread mill's flutes are a mirror image of the thread form itself, generating it as they pass. It works like any milling cutter, removing material radially, along its peripheral edges. Unlike cut and form taps, though, it’s far more flexible in terms of feedrates, thread size, and programming approach. However, form taps are limited to ductile materials like aluminum, stainless steel, and superalloys, and should not be used with cast iron or hardened steels.Ī thread mill also requires a pre-drilled hole. These follow the same basic rules as cut taps insofar as feedrate and tool geometry, but require a slightly larger pilot hole to allow for the displaced metal. Instead, they displace material, much like the thread-rolling process mentioned in the introduction. There are also forming or roll taps, which produce no chips at all. Spiral point taps tend to drive chips forward, whereas those with spiral flutes direct them upwards, out of the hole. Plug taps are generally used to thread “through-holes” while bottom taps are as their name describes, able to produce threads up to the very bottom (almost) of blind holes. Just as there are many different types of threads, so does a wide variety of taps exist. The two caveats to this are as follows: there must be a hole slightly larger than the thread’s minor diameter (taps are not drill bits and only cut on the tool's outer edges), and the feedrate must be precisely equal to the thread’s pitch-a 1/4"-20 tap, for example, must advance 0.05" per revolution (or 20 threads per inch) to produce a good thread. Taps work much like any other rotary tool, in that they’re gripped in a chuck, collet, or special “floating” toolholder (more on this shortly) and then driven into the workpiece at a specific feedrate. These grooves are used to conduct chips up and out of the hole during machining, just as the sharp edges on the end and periphery are used to cut the threads. As noted, threading is complex stuff, so let’s eat the threading elephant one bite at a time.Īt first glance, a tap looks quite similar to a bolt or screw, albeit one with grooves running down the sides. Nor will we cover thread milling’s alter ego, single-point threading, a process commonly used to produce internal and external threads but which can only be performed on appropriately equipped lathes. There’s no room to talk about thread rolling, chasing, whirling, or other threading methods, all of which are limited to external fasteners-screws, in other words. What we will discuss are the two primary approaches to making internal screw threads- tapping and thread milling-and when to use one over the other. Coarse and fine, left or right, tolerance classes, form, angle, and pitch-we won't attempt to explore the near-encyclopedic amount of screw thread terminology or all the many types of threads in use today, except to say that most have a 60-degree form and fall under the metric or Imperial measurement system. Threads and threading is a complex subject. Threaded fasteners hold the world together. So would bicycles, computers, refrigerators, and virtually every other modern electromechanical device. Since the dawn of electricity, though, we've used pumps to move fluids, which would be impossible or at least very difficult and expensive to manufacture without threaded fasteners. Historians will tell you that the screw thread was invented more than two millennia ago and was originally a means to bring water to thirsty crops and people. In selected cases, a procedure can be done through the ear canal in which the inner ear is reinforced. This is done through either an incision above the ear or behind the ear. The most commonly used procedure is a resurfacing or plugging procedure to correct the bony weakness in the balance canal. There are several procedures that have been used for this condition. Patients with significant balance issues may require a team approach with balance therapy with a physical therapist. In other patients, symptoms may be so severe as to require medication to limit symptoms or surgery to treat the abnormal inner ear canal. Particularly if a patient has limited symptoms, such as a full feeling in the ear or mild hearing loss, it may be decided to simply monitor the condition. In many patients, this condition does not require treatment. When patients have this condition, the fluid mechanics in the inner ear are abnormal and this results in sounds and pressure in the ear causing abnormal stimulation of the balance system. This test involves presenting sounds to the ear and measuring muscular changes in the large neck muscle that runs from the upper sternum to the ear called the sternocleidomastoid muscle. This condition is typically diagnosed with a history and physical examination, a CT scan of the inner ear, and an electrophysiological test called a cervical VEMP. Patients often hear internal sounds in the body at an abnormal level through bone conduction, and can have changes in hearing levels of varying types. Others may have a full constellation of symptoms that include hearing one’s breathing, pulse, or other sounds in the ear, as well as vertigo with loud sounds in the ear or visual disturbances with hearing loud sounds or doing straining or exertional activity. Many patients with this condition are asymptomatic or may just feel a full feeling in the ear. This disorder can cause a number of very strange symptoms to occur. Superior semicircular canal dehiscence is the name given to a disorder in which the normal dense bony covering of one of the three canals in the inner ear is thinned or missing. An unusual group of symptoms can accompany an unusual disease. Since this is in general not a comfortable position to be in, this condition can be treated by placing a stent across the compression and thereby propping the sigmoid sinus open.Hearing one’s own breathing or eyes moving…Dizziness with exertion or straining… A full or blocked feeling in the ear…hearing loss. If that is the case, the person usually only gets pulsatile tinnitus on one side, and not in both ears, and if the head turns to the side of the noise, by turning the chin to the shoulder, the jugular vein gets compressed and the noise goes away. If there is a compression of that sinus, then the turbulence can cause pulsatile tinnitus. The sigmoid sinus is a large vein that runs behind the ear and connects to the jugular vein in the neck. Those veins are quite big and run in the bone hence doctors refer to them as sinus. Turbulent flow can also occur when there is a narrowing in one of the veins that are carrying blood from the head back to the heart. High blood pressure can worsen the noise, and an ultrasound of the neck can diagnose this condition. Those narrowings typically involve the carotid artery in the neck. This flow then becomes noisy in the same way that a smoothly running river will become noisier at a set of a waterfall. Pulsatile tinnitus could be caused by an issue. If the inside of a blood vessel becomes irregular due to atherosclerosis (hardening of the arteries) or other injury to the arteries such as a dissection, the blood flow will become turbulent rather than smooth when squeezing through that irregularity. Some people notice tinnitus that thumps or whooshes in time with their pulse. Also your app needs to be a little bit more easier to use. I think I should be getting more protection for 9.95 a month.

The FAA said it has been working to fix staffing problems in New York City and other parts of the country - and even asked airlines to cut down on their summer schedules. Industry experts have recently warned that the summer season will be rough for travelers in part because of lingering air traffic controller staffing issues and overscheduling by airlines. The system is just uneven right now,” said Buttigieg. The scheduling issues come amid an expanding lack of personnel, including about 32,000 pilots, mechanics and air traffic controllers, according to a CBS News analysis of data from the Federal Aviation Administration, DOT and Department of Labor. The airline, which apologized for the rash of cancellations after a massive storm, did not respond to a request for comment by CBS News. Summer air travel issues likely to continue, experts warn 31, software and staffing issues forced Southwest to cancel 14,042 flights, which was 72.3% of all canceled flights nationwide, the outlet reported, citing Department of Transportation (DOT) data. Flight delays and cancellations plaguing the airline industry amid “unrealistic scheduling” and staffing shortages may last for another decade, according to a report. “Some of the predictions I’m hearing is that the pilot shortage won’t be resolved until 2032 or something like that,” data and industry expert Dean Headley told CBS News.īuttigieg’s office confirmed that Southwest Airlines is among the companies under investigation but declined to name the others or provide a timeline for the process. However, some fear the trend in staffing issues means the problem could get worse - and affect travelers for another decade. It took years to get this way,” he warned. “This is not something that’s going to be worked out overnight. “If you look at the delays, for example, that America experienced through last year in the summer 2022, a lot of that was driven by these companies not having the staff that they needed,” Buttigieg said. Transportation Secretary Pete Buttigieg told CBS News his office is already investigating several airlines for “unrealistic” scheduling by selling seats on planes without the staff to get them off the ground. The recent spate of flight delays and cancellations may persist for as much as a decade - due to a shortage of some 32,000 pilots, mechanics and air traffic controllers, experts are warning.

The high end didn't take your head off anymore and being able to dial in some more high end allowed us to get back some of that VOX vibe we were missing. The difference was actually a little less than we expected to hear but it was still very noticeable and the amp warmed up and we were getting a much more tolerable tone with single coils. It took a little cooler grade of the JJ EL84's to get to the same bias point and we finished it off with a nicely balanced tube for the phase inverter in V3 and a couple ECC83S's. The plate voltage clocked in at 330 volts and the stock sovtek EL84's were out of match by about 7mA and on average were running slightly over 100% which is fine for a cathode biased amp. The first thing we noticed was the speakers were hard wired and needed to be unsoldered to remove the chassis. It sounded ok, but quite sterile with a real brittle high end and it was really missing the personality we heard from the NAMM demo amps. We were looking forward to getting the first one thru the studio here so we could have our way with it, and it only took a couple months before our victim showed up! We thrashed on it for a while and laid it face down to open her up. They sounded good but didn't bowl us over, with single coils they had a pretty good chime. But we're talking tone here so our minds were open. We can't say that we were not disappointed that Korg had gone to china because we would rather not support their brutal oppressive government. We first heard the chinese AC30CC Custom Classic amps in January 2005 at the NAMM show and our first impression was favorable. Then there are the expensive hand wired AC's from 2002 and if you really want the traditional sounding AC and money is not an issue then the AC30HW is a nice addition to any players arsenal. We have tubed a number of the Rose reissues and we prefer the Korg reissues over the these. They have a nice vibe and we've been able to A/B them multiple times with original AC30's and for a PC board amp they compare pretty favorably. Plug a Strat or a Ricky into an old AC50, strike an open chord and you will know why The Beatles sounded the way they did! So climbing out of the Wayback Machine, Korg has owned VOX now for quite a while and in our opinion they did a very nice job with the 90's reissue AC15's and AC30's. Probably one of the most overlooked VOX amps until about 2000 were the 1964, 19 AC50's but the word has gotten out and the prices on these just keep escalating at an alarming rate! These are great sounding amps with all the sparkle of the AC30's but fatter with more punch and headroom. We are definitely fans of the old VOX amps and of the 90's reissue AC30's which are pretty good too. We have Retube Kits up in the online store for the 90's AC30's and for the new chinese AC30CC's, C2's and the AC15CC's and C1's. There’s a total of eight USB 3.0 ports (including the two at the front), two eSATA ports, two Ethernet ports, and an additional four USB 2.0 ports. Lidless glasses and the Mach V should be kept separated at all times. And don’t think that the guard completely protects the ports, because while it prevents direct contact of solid objects, it is perforated to allow for exhaust of hot air. This is particularly true with the Mach V, because the I/O guard is stiff and takes a bit of effort to remove or replace. While this protects them, it largely negates the ease of access to be gained from putting the ports up top. The ICON2 enclosure, like many cases that offer this layout, solves that issue by placing a guard over the I/O ports. However, doing so presents a problem – how do you protect those sensitive ports from damage? They’re now vulnerable to spills, falling objects, and the rumps of errant pets. Rotating a PC’s internal layout so that the motherboard I/O panel is at the top of the case seems as if it would be convenient for connectivity. While the front panel door must be swung open to access the card reader and optical drive, all of the forward-facing ports (such as USB 3.0) are located on the front top edge of the case along with the power and reset buttons, providing a perfect combination of refinement and functionality. One might think this could lead to boredom, but a light-up Falcon Northwest logo on the front of the case provides the dash of spice it needs. The Mach V’s exterior is a clean design that doesn’t even offer a case window. The power supply resides in its own physically separate compartment and the hard drives are placed in the intake path, which means they’re kept cool without excessive use of fans. Like the Raven enclosures, the internal layout has been tilted so that the motherboard I/O panel faces upwards, allowing for better exhaust of hot air (heat naturally rises). In many ways it is similar to the Raven series, which is built by Silverstone for consumer purchase, and used by many PC manufacturers for high-end gaming and workstation computers. Unlike the enclosures used by many other companies, this one is a custom solution crafted by Silverstone specifically for the Falcon Northwest Mach V. The Mach V has only one case option, the massive black ICON2. Let’s dive in and see if the Mach V can live up to its price. The Origin Genesis we tested in June retailed for $5,499, and the iBuyPower Erebus reviewed in May was $7,670. The total price of our unit rings up to $5,688, which is staggering, but not surprising. Equipped with an Intel Core i7 3930K (overclocked to 4.5GHz) and two GTX 580 graphics cards in SLI, it represents the cutting edge of what’s currently available to consumers. Our review unit was no base model, however. You simply can’t buy a Mach V that isn’t a performance monster. Even the base Mach V P67 system has a liquid processor cooler and a GeForce GTX 570 graphics card. You need to select upgrades if you’re a serious gamer.įalcon Northwest’s approach is different. We’d argue, however, that those base configurations offer merely adequate performance. That’s a non-trival chunk of change, and much more expensive than the base configuration of competitors like the Maingear Shift and Origin Genesis. You can grab yourself a Mach V for just a hair over $3,000 if you choose a AMD or Intel P67 platform. The Mach V is at least a gaming powerhouse, and at most a tribute to the kind of computing excess only true geeks can understand. Falcon Northwest has been offering computers under the Mach brand name for years, and while the hardware obviously has changed, the purpose has not. Just as we suspected.In the realm of flagship gaming desktops, Mach V is a name that means something. It could also be the dual graphics card capability, quad-core CPU support, and great overclocking capability. I've found that the more capital letters a part has, usually the better it is for gaming. Why does Falcon Northwest CEO, Kelt Reeves, think the EVGA nVidia nForce 680I - SLI makes for a good motherboard in a gaming system? "Mainly because it has a lot of letters, some of which are even capitalized.
