The answer came 1951, when two companies teamed up to begin researching a new idea: a small, portable radio. The question is, when could they make it happen?” “But it was obvious to everybody that consumer grade radios based on transistors would be a good thing. “The military is buying all of these things they can get their hands on,” says Harold Wallace, a curator at the National Museum of American History. military, recognizing the transistors’ potential to improve everything from radars to rockets, quickly seized on the new technology-to such a degree, in fact, that several years went by before it was applied to consumer products. For this, all three would be awarded the 1956 Nobel Prize in Physics. While the devices of the time relied primarily on the more delicate, energy-inefficient vacuum tube technology, the transistor, which used semiconductor materials to amplify electronic signals, allowed for products that were smaller, more durable, and more easily produced. It was in December 1947 that engineers John Bardeen, Walter Brattain, and William Shockley debuted the transistor effect, the building block for all modern electronic devices, at Bell Labs headquarters in Murray Hill, New Jersey. ![]() ![]() would have been in vain,” he wrote.Īmong the technologies to develop from this burst of wartime innovation was radar, wizardry that would eventually lead to the the transistor. The race between the Allies and the Axis powers to achieve technological and innovative advancements was what Churchill called the “Wizard War.” Without science and technology “all the prowess of the fighting airmen. As World War II gripped Europe, Winston Churchill knew that the conflict would be fought on two fronts-on the battlefield and in the scientific lab. ![]() ![]() ![]() As always, you should use whatever optic you are most comfortable with, but there is definitely something special about the Axial Arms 3x clean optic that keeps players coming back for more. The Axial Arms 3x optic is the perfect companion for this gun's ideal range. With 45 Rounds, this gun is capable of taking down multiple opponents without reloading. Having 45 rounds is going to be particularly important if you are taking this gun into the Iron Trials, where people have increased health pools and require extra bullets to kill as a result. It won't do much for your vertical control, but making the recoil pattern more up and down is essential to making this gun's recoil controllable at long range.Īs with most rifles in Warzone, having extra bullets in the mag is always good news. ![]() So it makes up for the recoil penalty on the RPK Barrel and then some. The Spetsnaz Grip is an underbarrel attachment that will improve your horizontal recoil with the AK-47 by 18%. Overall, this is the attachment that is going to help you be effective in those long-range duels, making this gun a great replacement for the Krig-6. It will add a bit of recoil, but we'll be counteracting that with a grip later on. For the AK, this is going to up your damage by 8%, increase your effective damage range by 50% and increase your bullet velocity by 50%. The 20" Spetsnas RPK is exclusive to the AK-47, RPD, and the FARA in Warzone. The GRU Suppressor will help you keep a low profile on the battlefield and will also slightly reduce your recoil, which is good on a weapon as kicky as this one. Luckily, there is a lot that can be done with weapon attachments to minimize its handling issues and make this gun much more deadly at long and short-range alike.īest attachments for the AK-47 (CW) in Warzone Season 5Īs with most weapons in Warzone, you are going to want to suppress the AK-47. The biggest downside to the AK-47 is that it is relatively hard to control in its stock form. The Cold War iteration of the assault rifle performs very well in comparison to its Modern Warfare counterpart thanks to its immense damage output and ease of control in mid-range engagements. It has a relatively low rate of fire around 600 RPM, but when it is combined with its very hefty damage to hit of 36 to the chest and 54 to the head, it has one of the fastest TTK's in the game if you can hit a headshot in there. The AK-47 assault rifle is one of the more unique weapons available in the Warzone arsenal thanks to its two available variants. Primary Weapons Secondary Weapons Perks Equipment.

However, such powerful magic doesn't come cheap. These mystical buildings will instantly teleport the player to a specific location. For a more permanent way to access warp technology, players might consider building Obelisks on their farm. While Warp Totems can be useful for this, they are consumed after each use, forcing the player to spend resources to craft them again and again. By cutting down on the time they spend running back and forth between areas, players have more opportunity to mine for treasure, catch fish, plant their crops, and explore exotic locales - and still get home before they pass out at 2 a.m. Not only does this give the farm a much better look in terms of biodiversity, but it is also cheaper than constantly purchasing grass/hay as cutting grass only yields a 50% chance that the 1 hay is added into the silo's inventory.Fast travel makes any game easier, and Stardew Valley is no exception. This way, the grass inside the fenced area will grow continuously, allowing the animals to have lots of food to graze on during the day, without depleting the hay stored in the silo. Livestock need hay and although it is a good idea to invest in a silo to store all hay that is cut from the land, it's much more cost-effective to build a large fenced area around the livestock housing to allow animals to roam free during the day.Īllowing the grass to grow only within these areas will save a lot of time and money in the long run. It's best to keep these numbers in mind to help keep all crops healthy and safe from night critters.Īlthough it can be tempting to get rid of any pesky patches of grass to keep a cleaner-looking farm layout and to optimize crop and furniture space, try not to rid the land of all of its greenery! Any livestock animals that are housed on the farmland require their own upkeep in the form of food. The same principle goes for the usage of scarecrows while they do their job and scare animals away from eating the crops, they still have a limited area of effect. Learning exactly how far crops can be planted around the sprinkler can help optimize a workday knowing which crops need to manually be watered and which are already taken care of by the sprinklers. Each level of sprinkler costs different materials in order to craft and have different areas of effect. Instead of manually watering each and every crop with a watering can, the player can opt to craft sprinklers. Watering and tending to crops can be a tedious process, yet nonetheless must be done every day. Neglected crops won't grow and can even be eaten by crows by the morning time. In the beginning stages of the game, it is important to keep all crops watered and cared for on a day-to-day basis as for a while, they will be the only real source of income. The area of effect (or AOE) is the range in which a certain object's effect can reach and it is crucial to setting up not only the most aesthetic farm layout but the most efficient one as well. These suggestions are especially valuable for newcomers to Stardew Valley who are still coming to grips with the game. ![]() For extra convenience, the most important points have been highlighted and two new tips have been added to the ever-growing collection. As developer ConcernedApe devotes his time to always giving back to his supporters in the form of free patches, the tips and tricks to optimize a playthrough remain ever-changing and growing. Updated August 24th, 2021 by Christine Mendoza: As Stardew Valley continues to be a go-to comfort game for many fans, its popularity is still going strong. Whether they're aiming for a cozy build or an extravagant one, here are a few simple (yet effective) tips that can help any player make their beloved farm layout amazing. Still, there are some great pointers that any Stardew Valleyfan can get behind in the event they decide to seek out some tips. Preference is everything in the end - what works and makes each player happy is a great build.

The Fitbit Sense was also released at the end of September 2020 as the most advanced product of the brand. ![]() The feature to store music on the device that was available on the Versa 2, is not available on the Versa 3 although they advertise it on the box. These features and the addition of a speaker required a slight increase in the thickness from 12.15 mm to 12.35 mm. Android users can answer phcalls using the Versa 3. More improvements to the previous model include Active Zone Minutes, a display with a higher resolution, and fast charging. This model adds the GPS function compared to its predecessor, Versa 2, and Google Assistant integration. The Fitbit Versa 3 was announced in August 2020 and released at the end of September 2020. New features include Amazon Alexa, 24/7 heart rate tracking and sleep tracking. The Fitbit Versa 2 was released in September 2019. In addition to all the Inspire 2's features, it has an Oxygen sensor, stress tracking, and an always-on display mode. The tracker looks similar to the Luxe tracker, a more premium version of the Inspire. But it does not have music control or music streaming feature like Fitbit Charge 4.Īnnounced in August 2022, the Fitbit Inspire 3 was released on September 15, 2022. The features includes heart rate monitoring, sleep tracking female health tracking and 5 days of battery life.

However, this is a fashion-forward fitness tracker that mainly targets the female users. In terms of features and specifications, it is almost similar to Fitbit Inspire 2. Fitbit Luxe įitbit Luxe is a fitness tracker released on 30 April 2021. The Fitbit Charge 5 is said to be redefining how you overall track your health & well-being while keeping in mind the pulse of your fitness, heart health, stress & the add-on ability to track your body to carry out the required workouts. The Fitbit Charge 5 is a tracker released in September 2021. In addition to all the Inspire HR's features, it has an improved screen, double the battery life & new Active Zone Minutes feature. The Fitbit Inspire 2 was released after the Charge 4 in 2020. An optional clip-on accessory allows the Inspire HR to be worn in other locations such as a belt, waistline pocket, or bra. There are also two different strap colors. According to Fitbit, once kids outgrow the design, they can use their Ace 2 or Ace 3 with any Inspire, HR or 2 bands and accessories.Īnnounced in February 2019 in three different colors: black, lilac, and white. The Ace 3 is a slightly smaller version of the Ace 2, only with a curved screen and a smaller band. In March 2021, the Fitbit Ace 3 was released. In March 2019, the Fitbit Ace 2 for kids aged 6 and above was released. Released in March 2018, the Fitbit Ace is a version of the Alta for children aged 8 and above.

I've also messaged ebay sellers for parts, but no one has the board, and the least expensive out-of-service unit I could find is well. I've got a basic oscilloscope, multimeter, and a shitty but good enough signal generator, but I'm way too worried about frying one of the chips on the board as I have absolutely no idea how they work together. I couldn't find any info on that piece of hardware and the reason it might fail. Unfortunately, there are quite a few ICs in there, and my knowledge only goes so far. Regarding the issue with the display on the equalizer (this post), I'm going to redo every soldering joint on the analyzer board, then pull out each transistor and test it, then pull out each cap and do the same, before recapping it. The service manual is available here, and the whole schematic is available but I don't know enough in order to figure out what could be the issue unfortunately, so if anyone is able to help I'd be very thankful!Ĭlick to expand.I know I should begin by doing so, and I already fixed the preamp (dbx-cx3) by replacing the output muting transistors, and one of the opamps, which is the primary reason I'm willing to recap everything, as I'm pretty sure both those components failed because of a janky voltage rail. If anyone has the board for the screen and is willing to sell it, I'm interested. I've also tried looking at a 'for parts' unit, but they go for $150-250 in non-working condition here in Europe so that's not a solution I'm keen on as of now. Picture of the issue, where we can clearly see some rows and lines not working: ![]() If anyone has information on the way that screen is driven, and what could be the issue, please share it as that would be of tremendous assistance. My understanding is that it's an expansion and heat-creep-related issue, and I went ahead and redid all the solder joints in the area of the screen hoping one of them was cold. Only noticed this in the last couple of weeks, and have been using the equalizer for 3 years. Then it comes back on and works again and stays like this. ![]() The right side of my analyzer display (neon tech I believe) is turning on upon power-up, before giving out for about 15mins while playing. I also have a little request for help from the knowledgeable people here, as I was unable to find an answer even after doing three days of research (shame on me maybe?): Picture of my unit running (sorry for the bad quality, will do one better once I pull it out of my system): Kept every single cap with the same rating capacity-wise, but upgraded some in their voltage ratings as it was far cheaper on large quantities (grouping with my DBX-CX3 MKI for the order).įor documentation purposes, I'll be attaching clean pictures of every board once I take them out for soldering, and I can already post my parts lists for the recap. When choosing capacitors, I went with either the cheapest 'audio' Nichicon or general-purpose caps when they presented better specs on paper (used ripple current and service hours as a metric, as they don't include their ESR ratings unfortunately). I'll be replacing all electrolytics without distinction as to where they reside in the equalizer, along with upgrading the plethora of 4558D with NE5532P. Recently, however, I've tackled some issues with my preamp, and while at it thought I'd group my order for a recap of both this equalizer and the problematic preamp. The first owner was my father, unit was never serviced, and stayed powered off for most of the last 20 years (except the last three lol). The Sound has the 'warm' feeling from old caps and the power supply caps for sure need to be replaced, hence that thread. I've been using this beautiful unit for a little while now and thought everything was fine, although a bit crunchy when pressing buttons. ![]() ![]() ![]() We did this for my granddaughter who really wanted to be able to interact with these animals.

Fragments of shale separated from coal during processing may also be called slate. In addition to slate, writing boards have been made using soapstone or clay.Īmerican coal miners may refer to the shale forming the floor and ceiling of a mine as slate. Shale and mudstone produce a dull thud.Ī sheet of smooth stone used for writing might be referred to as a "slate," regardless of its composition. Slate emits a "tink" or a ring when struck. One way to tell shale and slate apart is to strike it with a hammer. However, if you're looking at a partially metamorphosed rock, it's difficult to say whether it should be categorized as slate or as shale. In the modern usage, geologists say shale is converted into slate. In the past, the terms "slate" and "shale" have been used interchangeably.

They have also been used as writing slates, i.e. Slates have been used historically as building stone, since, due to their strong fissility, they make excellent roof tiles. ![]() With increasing metamorphic grade, slate develops a lustrous sheen related to coarser white mica grains that are able to reflect light, thus becoming phyllite. Slate is usually gray or black and is used to make blackboards and roofing tiles. Slate colors are highly variable depending on the mineral content: dark varieties generally containing much graphite and green varieties containing abundant chlorite. The minerals present in slates are white mica (illite, smectite, pyrophyllite), chlorite, graphite, kaolinite, quartz, feldspars, and oxides, representing a mixture of metamorphic and detrital grains that are largely too fine-grained to be seen with the unaided eye. ![]() This is an easy to moderate grade with several stream crossings. Such foliation does not necessarily correspond to the original bedding or layering and rather represent tectonic surfaces, often perpendicular to the direction of maximum compression. Starting at the eastern end, this trail begins by following Slate Rock Creek. The preferred orientation of platy phyllosilicates, resulting from the metamorphism of clay minerals, determines the penetrative foliation characterizing slates. Slate form from very low-grade metamorphism of clay-rich sedimentary rocks (shales, mudrocks, siltstone to very fine-grained and matrix-rich sandstone) or volcanic ash deposits. The related term ‘clay slate’ is a direct translation of the German Thonschiefer and the French schiste argileux, which is redundant in English. The name itself derives from the German schleissen, ‘to split’, in reference to the high degree of fissility of the rock. Slate is an ultrafine/very fine-grained schistose metamorphic rock characterized by a slaty cleavage and, consequently, tends to split easily along foliation planes. ![]() |
