However, this game is a lot more sexually charged than anything in the series. The third game is a lot darker than the previous game, but doesn’t match the dark tones of the first game. However, some of the more sinister undertones from the first game do leak over into this installment, making it a typical coming of age story. Instead of continuing with the depravity of the first game, this installment gave audiences a naïve, sheltered protagonist who has to learn about the world throughout the events of the game. The second game isn’t as dark as the first game because of the change of direction. These elements had to be toned down for international audiences, but little tidbits were left to allow the audience to catch on. The supporting cast is no better as it features a pedophile, a child eater, and a genocidal dragon. The protagonist is a blood-thirsty sociopath whose sister wants to have an incestuous relationship with him, much to the dismay of her fiancé. It’s no secret that the cast of the first game is full of morally gray, many would go as far to say morally black, characters. These themes had to be toned down in many versions outside of Japan. While these games do have some mature themes hidden in their narratives, Drakengard has them out in the open and is unapologetic about it. The game wasn’t entirely forgotten though as it got a novella that follows ending B, The Garden of Light, but that’s all it got.ĭrakengard sought out to stand out against the cookie cutter goody two shoes stories that Final Fantasy, Persona, and Dragon Quest offer gamers. In many cases, this game is forgotten by fans as it wasn’t directed by Yoko Taro and falls into the cookie cutter JRPG tropes the other two games mocked. The novellas, The Stone Flower and And Then There Were None follow the events of ending E which eventually led to the events of the Nier series.ĭrakengard 2 is in its own separate timeline that features the characters from Drakengard 1 as it is influenced by the events that took place in its timeline instead of the timeline of the first game. Drakengard 1 has five endings, but only one of them, ending E, leads to further expansion in the lore. The novella ending in Drag-On Dragoon 3 Story Side leads to the events of Drakengard 1, which makes Drakengard 3 an alternate prequel to Drakengard 1.ĭrakengard 1 begins in its own timeline and has a prequel titled The Song of a Fourteen-year-old that introduces the characters of the game. Drakengard 3 is the series with the most prequels as it offers introductions to the main females of the series through a comic titled Utahime 5, a series of novellas that focused on the main characters, and even a DLC prequel story in the game.ĭrakengard 3 has 4 in-game ends and one novella ending, but one in-game ending, A, leads to a different future that’s told in the sequel side manga, Shi Ni Itaru Aka and a collection of novellas titled Drag-On Dragoon 1.3. The three games start off on their own dimensions and all of them have multiple splits that create different futures, but there are more prequels than epilogues to these games. This creates a cohesive cross-dimensional universe that has fans wanting more lore. The addition of novellas and mangas to supplement the games also gave fans new content that allowed them to immerse themselves into the lore of the series and see what would’ve happened based on the events that didn’t end with the literal apocalypse. The series has three main line games that at first glance don’t connect, but with the addition of novellas and mangas, a coherent timeline was set and allowed players to see what was canon and what wasn’t. There are three games in the official Drakengard series, so we’re going to focus on those, for those interested in Nier, check out our article revisiting Nier’s legacy. The series is most notable for its expansive world building and mature themes with its overall morally gray characters which make this series divisive among gamers. The series is considered extremely popular in Japan, but has gotten mixed receptions outside of Japan.ĭrakengard is a hack-and-slash medieval RPG series that’s set in the world of Midgard, but the first game begins in a fictional Northern European setting, and as the series progresses, becomes more and more modern as seen in Nier Automata. Drakengard, or Drag-On Dragoon in Japan, series throws all of goody two shoes fluff out a window and gives players a brutal story with uncomfortable topics that have left players pondering the human condition. Many video game franchises are known for their whimsical worlds, cookie cutter characters, and hopeful messages.

Make sure you turn your transmitter off when not in use, as some vehicles won’t automatically deactivate them. Can I use a Bluetooth FM transmitter on my boat?Īs long as your vehicle has an FM radio connection and an auxiliary port, it can be used to establish a Bluetooth connection. Always check that your transmitter is turned off before leaving your vehicle. If you leave a Bluetooth FM transmitter on when your car isn’t running, then yes, it can drain your battery. Will a Bluetooth FM transmitter drain my battery? Be sure to choose a clear frequency, as ones in use will not work with a transmitter. Most manufacturers provide a range of available FM frequencies that can be used for pairing. You’ll want to match your transmitter’s frequency to that of the desired station on your radio for streaming. How do I know which FM frequency to use for my Bluetooth FM transmitter? For more information on our testing methodology and how we evaluate every product, check out our methodology page here. We publish hundreds of product and service reviews to bring car enthusiasts detailed guides on automotive tools, detailing kits, car seats, pet products, and much more. Our team of product testers thoroughly researches top products, unboxes and puts our hands on each component, and tests the items on real vehicles before making recommendations to readers. Transmitters with more features and an intuitive design for a more user-friendly experience scored highest in this category.Įach year, we test over 250 auto products on vehicles and in our testing lab. This included the number of ports, extra features, and design. Versatility: This category measured the additional functions of each transmitter. Transmitters that worked reliably without interruption scored highest in this category. We factored in how easy it was to stream music from a phone, the reliability of taking calls, and how consistent the connection was during the duration of our testing process. Streaming and Calls: This category measured the clarity of music streaming and phone calls. Transmitters that were installed with little hassle and connected quickly without difficulty scored highest in this category. Once installed, we linked each transmitter to our phone. Installation: This criterion measured how easily the Bluetooth FM transmitter was installed into our vehicle’s auxiliary port, also known as a cigarette lighter adapter. A phone call was made to another product testing team member to test the hands-free calling features as well as the clarity of each call. At least two songs were streamed using Spotify ® to test clarity. We used a 2014 Honda Civic SE to test our Bluetooth FM transmitters. Each one was paired with an iPhone 12 Pro. Each product was given a rating out of 5.0 stars based on this criteria. A team member tested each product on a car, taking note of how easily the transmitters were installed in our testing vehicle, how well they streamed music and handled phone calls, and how versatile their features were. Our testing team ordered the five Bluetooth FM transmitters that best met these standards. We started by searching Amazon for top products, looking at factors like Prime shipping eligibility, customer ratings, Amazon superlatives, and prices. The best Bluetooth FM transmitters in this article went through two rounds of reviews. Bluetooth FM Transmitters: Our Testing Process In the first day of RW, most member of BW had ended up in skirmishes with them, one of the few successes came from ASSASSIN-BW, a newer member at the time, though he soon vanished due to lack of clan support. With about half of BW joining RW and a few joining TK, BW was in serious problems. What was to follow was going to shape the BW you know today. After the formation of RW (COP)ANDY-BW came back to Sherwood thinking that BW was dead and founded his own clan called FB (Fallen Blades) which would later be renamed to TK(Templar Knights). In this chaotic period (SGT)JIMMY-BW left BW and created RW (Red Warriors), he also renamed himself to DARK-LORD. With countless wars with AOD and DH (Dream Haunters), BW started to fall into ruins and members got disgruntled at the leader. But trouble was brewing on the horizon and BW would be thrown into chaos with an uncertain future. The early years were a time of glory as BW were a plenty and all feared them in the beginning. The exact date of BW’s foundation is surrounded by much controversy the first post on BW’s first guestbook is from as late as 2006 while many old BW members have claimed that it was founded in 2004. Founded by WARRIORCHIEF for the purpose to become the most successful and fearsome clan Sherwood has ever laid eyes upon. Long ago in a distant land, the Black Warriors (Henceforth BW) came together. DTC OFF - This option is to delete Trouble Code (DTC) related to the engine.This may affect long term engine reliability. Caution, this process must only be used on vehicles with a full race exhaust. Pops & Bangs - Pops and bangs (burble tune) is the result of an ignition delay which creates an exhaust detonation when the throttle pedal is released.Race Exhaust - This option is for those running full race exhaust systems.Vmax Off - This is an increase or reduction of the maximum speed limit.Where your car is sluggish off the line, your newly flashed car picks up right away and pulls harder through the mid and top end RPM range. Your car will have much better throttle response all the way to redline. The biggest difference when you flash your car is the overall improvement of the power curve. With our ECU tune, you are able to gain improved performance on the engine. greatly appreciated.VR Tuned offers an ECU flash for your Volkswagen Golf GTI MKVI. that is if anyone has done this yet? :laugh: thanks in advance for any numbers you guys have. I realize this too, I'm just looking for apples to apples after a tune- with the same set up before and after to see if there has been improvements and what those are. oh, and before I start hearing the comments about other things I should do first, yes, yes, yes, I know I need better wider rubber, lighter wheels, LSD, suspension mods, etc. Before I spend the money on an engine performance mod like a tune it would be very helpful to hear comments from the community as to what they are getting in terms of some of these types of performance measures. and better flex (more travel), departure and approach angle, and traction on the rocks and mud if its a 4x4. dyno numbers are good for comparisons on paper, but typically I don't do a lot of expensive mods to my cars/trucks unless they actually improve real world performance- like better 0-60, ET, braking, skid pad, lap times on a given track, etc. Would be interesting to see actually rubber to the road numbers with the various pre-packaged tunes as well as any custom tunes anyone has done. I don't suppose in addition to road feel and butt dyno anyone has actually done any timed runs with cobb tuning maps vs stock? with or without bolt ons.

So you ended up with those two parts each with its own sequence of features, the last one of each being Johdon_pidikkeen_alaristikko and Pohjalevyn_toisto. I've taken screen captures to show what the 2 separate parts are, and colored the sequence of operations (features) that produced each of them: When you look at the Project tree at the left, the same sequence of operations (called "features") is shown, here from top to bottom, in chronological order, but without the benefit of seeing which feature belongs to which "branch". After forking at this point, you worked on two different parts instead of a single one. After that pad, you applied a mirror feature (Oikea_uloke_peilattu), but you also mapped Sketch002 to Vasen_uloke_pad_6 and padded it into Vasen_ulokkeen_kolmio. You see that at the 4th level (Vasen_uloke_pad_6), there's a fork. In a typical Part Design workflow, this tree should be linear, with one single straight branch. This shows the sequence of operations in creating your part, from the bottom up. Here's what the dependency graph shows about your model: Repetition host is a 3D printer software, which analyzes imported stl 3d file and eventually feeds the sliced G-code to the 3D printer. This is most probably something I do wrong with FreeCAD, but I just cant point my finger what that is This third version is a bit more complicated than earlier versions and thus impossible to fix and get it approved by repetition host anlayze.Īttached file is the problematic FreeCAD drawing.Īny help is appreciated. I have managed to fix the two earlier version by (trial and error) using FreeCAD's own mesh tools together with netfabb. This model is a third version of the drawing. That was necessary because selecting only last item would have left part of the features out of the exported model. The exporting to mesh file was done by selecting two last items from project tree list. I have also tried to fix the stl mesh file with FreeCAD's own mesh tools but they seem to broke the model even worse than it was before The model comes back as a manifold but there are errors easily seen from Repetition host preview image. I have tried to fix the model by running the stl mesh file through netfabb but without success. Repetition host says the model is not manifold and might not print correctly. The export succeeds but the mesh file is no good, according to Repetition host analyze. Now I would like to convert this drawing to stl file format. There is this simple 3D drawing that I have been building (as a novice FreeCAD user). This includes details such as authorship, copyright, and location - all of which are essential to publishing.I hope it is alright to use this thread trying to sort out another exporting problem from Freecad. Another disadvantage of STL is that the file can’t store metadata.For this reason, it’s mainly used for creating prototypes rather than the final product. While STL is great at printing complex shapes, it does have relatively limited capabilities in other areas - including color and texture.This makes STL a smart choice if you’re printing an object in a single color and material. Due to their lack of color and texture, STL files tend to be smaller in size yet faster at processing than other formats.Whatever shape you choose, it’s usually able to produce an accurate model. You can use an STL file to create a wide variety of objects - from lamps and plant pots to drone accessories and camera tripods.Because it’s pretty much universally recognized, it’s a reliable choice for designing and printing your 3D models or objects. Nearly all 3D printers can use and support the STL file format.Read on to learn more about the advantages and disadvantages of STL. However, several of its drawbacks also may mean it’s not always suitable for your needs. There are many advantages to using the STL file format. “This is not happening to me,” or “the doctor is wrong” gives you some hope.
In the upper image a Photo-SCR based opto-coupler’s internal construction is shown. SCR stand for Silicon controlled rectifier, SCR also referred as Thyristor. The photo-TRIAC based opto-coupler examples are IL420, 4N35 etc are example of TRIAC based opto-coupler. Opto-coupler provide excellent isolation in this case too. The led can be controlled using DC, and the TRIAC used to control AC. TRIAC is mainly used where AC based control or switching is needed. In the upper image the internal construction or the TRIAC based opto-coupler is shown. 4N32, 4N33, H21B1, H21B2, H21B3 are few photo-Darlington based opto-coupler example. The 6th pin which is internally connected to the base of the transistor, used to control the sensitivity of the transistor as discussed previously in photo-transistor description. This type of opto-coupler also used in DC circuit related area for the isolation. As usual the LED emits infrared led and controls the base of the pair transistor. In this configuration the Darlington Transistor provide high gain ability. In the upper image there are two types of symbol, internal construction of Photo-Darlington based opto-coupler is shown.ĭarlington Transistor is two transistor pair, where one transistor controls other transistor base. Photo – Transistor based opto-coupler is used in DC circuit related isolation. PC816, PC817, LTV817, K847PH are few widely used photo-transistor based optocoupler. In this configuration, false triggering due to noise or electrical transients can be controlled effectively.Īlso, before using Photo-transistor based optocoupler, the user must know the maximum rating of the transistor. Often the pin is used to connect with ground or negative using a high value resistor. This pin 6 is used to control the sensitivity of the photo-transistor. On the second image on the left, there is additional pin out which is internally connected with transistor’s base. Photo-Transistor can be further of two types depending on the output pin availability. The Transistor type can be anything whether PNP or NPN. In the upper image the internal construction is shown inside a Photo-transistor Optocoupler. Opto-coupler which use Photo Darlington Transistor.Opto-coupler which use Photo Transistor.Depending on the use there are mainly four types of optocouplers are available. There are many different types of Optocouplers are available commercially based on their needs and switching capabilities. The hollowed space between LED and photo-transistor can be made using Glass, air, or a transparent plastic, the electrical isolation is much higher, typically 10 kV or higher. Also, between the photo-transistor and the Infrared LED, the space is transparent and non-conductive material it is electrically isolating two different circuits. Since the LED can be controlled by a different circuitry and the photo transistor can control different circuitry so two independent circuits can be controlled by Optocoupler. Intensity of the LED directly controls the photo-transistor. The photo-transistor switches the output circuitry by its collector and emitter, same as typical BJT transistors. On the left side pin 1 and pin 2 are exposed, it is a LED (Light Emitting Diode), the LED emit infrared light to the photosensitive transistor on the right side. This the internal structure of the opto-coupler. In present commercial market, we can buy Opto-coupler with 10 kV to 20 kV input to output withstand voltage capacity, with a specification of 25 kV / uS voltage transients. Often in circuits, especially low voltage or highly noise sensitive circuits, Optocoupler is used to isolate circuitry to prevent electrical collision chances or to exclude unwanted noises. Optocoupler also called Opto-isolator, photo coupler or optical isolator. Opto-coupler is an electronic component that transfers electrical signals between two isolated circuits. |
