![]() ![]() ![]() To stop ShapeStim producing an enclosed shape, we set the closeShape parameter to False. We could work out the positioning of vertices along the required arc, but it is easier just to extract half the vertices from our oval stimulus, which has a property verticesPix. To do this, we will use a ShapeStim, which requires the coordinates of each vertex to be specified. Here, our strategy is going to be to create two new shapes for each oval one corresponding to the light edge and one corresponding to the dark edge. The tricky part is getting the outside lines to have different intensities. Circle ( win = win, radius = oval_radius_pix, units = "pix", edges = n_edges, fillColor = oval_fill_colour, ) psychopy. Window ( size =, units = "pix", fullscr = False, color = bg_colour ) n_edges = 128 oval = psychopy. Import psychopy.visual bg_colour = oval_radius_pix = oval_fill_colour = n_ovals_per_dim = 40 oval_col_ori_change = - 30 oval_row_ori_change = + 30 oval_edge_contrast = 1.0 oval_line_width = 3.0 win = psychopy. We will approach this by creating a different set of code to our main experiment that we can use to get a working stimulus without worrying about the other components of the experiment.įirst, let’s specify in code the above stimulus details and prepare a window: Now for the grid, let’s have 40 ovals both horizontally and vertically, spaced evenly between 20 and 380 pixels in the window.įinally, let’s make the change in orientation of successive ovals 30 degrees anti-clockwise across columns and 30 degrees clockwise across ascending rows. Ultimately, we will want to manipulate the intensity of the light and dark edges, but for now let’s set them to +1 and -1. We will give the line around the outside a width of 3 pixels. Now let’s think about each oval we will give it a lightish green colour, say, and a size of 10 pixels horizontally and 18 pixels vertically. Next, let’s set the background colour to a uniform darkish blue say. This is probably too small if we were running the experiment “for real”, but it will do for our purposes. Now that we have a qualitative understanding the key components of the stimulus, let’s make them quantitative so we can specify them in our code.įirst, let’s set the overall stimulus size at 400 pixels. Overall, the ovals are presented on a dark lightly-textured background of blues and purples. Looking at each individual oval, we can also see that one side has a white edge and the other side has a black edge. Moving up the rows from the bottom, we can see that the orientation of each successive oval is shifted clockwise from the previous oval. Moving across the columns from left to right, we can see that the orientation of each successive oval is shifted anti-clockwise from the previous oval. On visual inspection of the image above, we can see that it is formed from a grid of green oval shapes. Now we reach the tricky part-how can we create a stimulus containing the illusion?įirst, we need to closely examine our demonstration stimulus and determine its key components. Hence, we decide to run an experiment where we manipulate the difference between the intensity of the light and dark regions as our independent variable.Īs our dependent variable, we will have participants rate the subjective experience of motion on a scale from 1 to 5.Īs before, we will work through our experiment framework and build up the code as we go through. We have an inkling that the light and dark regions at the edge of each oval are critical to the illusion. ![]() We are interested in knowing what factors in the stimulus lead us to perceive the motion. Perhaps it was motivated after seeing the cover of the album Merriweather Post Pavilion by Animal Collective, as shown below. ![]() Our experiment involves a particular visual illusion in which a completely static stimulus appears to be moving, particularly around the time of an eye movement. In this lesson, we are going to work through the process of implementing another experiment in Python and psychopy. Be able to follow and understand another example of experiment creation and implementation in Python.Not sure if this makes sense - please let me know if I can provide any other information. In the begin routine tab as I thought this would restart its position, however, it resets the position each time the marker is moved (even within the same trial) - so the marker actually cannot be moved at all.Īny ideas how I can stop this from happening? I need the marker position to reset at the beginning of every trial to the (0, 0) position.

On the iPhone or iPod Touch, tap to the left of the waveform graph to switch the manual threshold slider on and off. But you can also manually control the threshold setting. Also, please use the manual settings if automatic decoding does not adjust to the frequency, WPM or background noise threshold level.īy default, the threshold (the signal level above any background noise required to detect a dot or dash) is set automatically by the AGC. So make sure to aim your iPhone so the the tones show up in the spectrum display. Please note that it is easy to mis-aim an iPhone's microphone so that its noise cancelling microphone will cancel out any Morse Code tones. (QRQ mode also supports higher frequency dot-dash tones.) There is a QRQ High Speed WPM Mode which will work better for code speeds in the range of 30 to 80 WPM. You can also manually set the WPM code speed using the plus and minus symbols that appear in the waveform graph, or the slider control on an iPad. One the iPhone, tap the lock button to the right of the waveform graph to lock and unlock automatic WPM detection. The Morse code WPM (words per minute) detection speed is automatically adaptive from about 8 to 40 WPM, and can be locked to the current estimated WPM dot speed (WPM lock icon locked). On the iPhone, tap the lock button to the right of the spectrum graph to toggle the filter off and on. Tap the spectrogram to set the audio filter to the frequency of a selected frequency peak. The filter can also be left off in a wide-band mode (frequency lock icon unlocked). If the audio filter is enabled (frequency lock icon locked), it can be set for frequencies in the range of 400 to 1400 Hz. You can then use the optional narrow-band audio filter to help filter out background noise. The Morse Code Decoder includes a built-in spectrogram to help determine the audio frequency of the Morse Code tones. Decoding parameters that can be manually adjusted include the audio frequency of an optional narrow-band DSP filter, the WPM dot/dash speed used for detecting characters, the threshold level of background noise, and whether Farnsworth timing is to be used for detecting spaces between individual characters. It includes both automatic decoding of longer clean signals and manual controls to allow the decoding of more difficult signals in QRM. The HotPaw Morse Code Decoder takes audio input from the microphone or headset input on your iPhone or iPad, decodes Morse Code, and displays the results in text form.

NoSQL - MongoDB, CouchDB SQL - Oracle, MySQLįor example, you can build a custom tech stack base like below for an application that has many user interactions, database interactions, and a global presence: Some technologies used for building the front end and back end of an application are: Tech stack components While no technology can guarantee 100% security, always go with technologies that follow a set of best practices to ensure maximum security of data and transactions and minimize vulnerabilities. Lastly, since you know the objective and size of the project/web application you are going to build, you can decide on the complexity of the stack and avoid using technologies and operations that are really not required for your project, and avoid bulky resources. Planning a technology stack ahead means you will already know the resources, infrastructure, automation, hardware, and other project requirements, thus saving both cost and time. Additionally, it becomes easier for developers to communicate about the functioning of the application. You can also pick a specific tech stack to leverage your current team’s expertise. If you choose frameworks and databases that scale well, during the planning phase itself, you will be saved from the horizontal and vertical scaling issues as your user base grows.Īlso, a proper technology stack will help speed up the development process as you can hire full-stack developers or experts in individual technologies. ![]() In general, a tech stack can be a frontend tech stack, backend tech stack, or a mix of both-i.e., a full stack.įirstly, you are more likely to build an application that can be used by a large number of people. You can learn more about the MEAN stack in our detailed tutorial.Īnother popular tech stack example is the LAMP, which stands for Linux, Apache, MySQL and PHP. Many full-stack developers find these stacks easy to learn and implement because of the common technology used throughout the stack: JavaScript. The MEAN and MERN stacks are trending tech stacks for web development. ![]() In the above diagram, Node.js is the runtime for the web applications, Angular provides the user interface, Express is a web framework built over Node.js, and MongoDB is the data platform or data stack that has the ability to transform data into a more usable form. You can replace Angular and use React, as in the MERN stack, since React is becoming equally popular, especially for single page web applications. MEAN stands for MongoDB- Express- Angular- Node.js. ![]() One of the most popular and easiest examples of a technology stack is the MEAN stack. ![]() ![]() ![]() “But at the same time, if I save one vehicle a week that’s great, but then I’m gonna be the guy that has cars rotting in my yard. I don’t have endless budgets, and I like to show people that you can have fun and put cars on the street and enjoy them, and they don’t have to be pretty and shiny, or the fastest. I’m just a blue collar, hard-working guy, I work seven days a week. “My heart will always be budget builds and ‘how can we make this thing run on as little coin as possible’ content. Vice Grip Garage continues to evolve in order to keep up with Derek’s long term vision for the channel. They were essentially doing revivals and ‘will it run’ scenarios long before they were content genres. Even then, a teenaged Derek would cruise in town with Chad, scoping out junkers and getting them running to use or sell. The couples have been friends since high school. In keeping with this desire to promote hot rod culture, Derek and Jessica loaned their NASCAR tribute 1974 Monte Carlo to friends Chad and Haley Asheim to compete at Sick Week. It doesn’t even have to be a younger generation, if we can get friends or family or whoever involved, it’s kind of a strength in numbers thing.” “Because when you and I are toes-up in the daisies, if there’s not another generation to pass the torch to, this whole hot rodding scene is done. “It’s great because that’s my whole goal, getting another generation involved,” Derek said. The youngest son, Bentley, even has his own YouTube channel called Little Grip Garage, which chronicles his revival of go-karts and dirt bikes, with Derek’s assistance if needed. She contributes content to the channel and their three boys are often included as well. Vice Grip Garage is a family affair, and Jessica is not stranger to spinning a spanner or two - on camera and off. And of course snacks, I made sure we had all the best snacks, including the cold ones.” By the end of the week I was also in charge of doing tire swaps and fuel. To start, I did all of the packing and organizing, I made sure we followed the correct route, got to the motel and so on. “I was basically in charge of all the logistics. “It was a lot of work, but an absolute blast. “It was everything I expected, and nothing I expected at the same time,” she said.

The body and the paint are going to stay exactly the same forever.”įor Sick Week, Kevin Smith from KSR Performance and Fabrication helped prep Independence. After I heard the story, I said, ‘Well, now I can’t paint it.’ That’s very special to me. “It was painted by the previous owner, Rhonda, and her dad - who is unfortunately no longer with us - as a memorial to 9/11, right after it happened. To show people that you don’t have to have a huge budget and a giant race program to come do events. My goal was just to get it to as many events as possible. We wanted to keep it budget friendly, but still have a lot of fun with it. “It certainly is a fan favorite. Independence is torn, tattered, and scarred - but much like this country, it never gives up. And I think maybe that resonates with folks. Independence has been prominently featured on his YouTube channel ever since he rescued and revived it a couple years ago. It was always being closely inspected by an eager fan. ![]() At Sick Week this year, it was nearly impossible to get a photograph of his rough-and-ready, stars and bars painted 1972 Chevelle known as Independence. The fact that Motion Raceworks was willing to just throw me the keys to El Toro, gave me insight to how amazing the drag-and-drive community is.”ĭerek enjoys attending car events and engaging with his subscribers. “I’m a pretty hard guy to get excited, but I can tell you that experience blew me away. The duo ran eight-second passes all week and successfully completed the event. The casual drive was in anticipation of one more exciting to come at Rocky Mountain Race Week, where Derek was teamed with with fabricator/mechanic John Matzen in the Motion Raceworks Coyote-powered Mustang known as El Toro. He drove Tom Bailey’s ice cream truck along the route for the week, getting his first taste for the motorsport niche. His initial foray into this style of motorsport was at 2021’s Midwest Drags - albeit in a spectating capacity. For a man who likes racing and working on cars, and can do so in any location no matter how inconvenient, drag-and-drive was a perfect sport for Derek to get into. ![]() ![]() ![]() In this way, you can play your converted audio files on the popular devices off-line, such as iPad Pro, iPad mini 4, iPad Air 2, MP3 Player, Android devices, Windows devices and more portable devices.
