![]() What it doesn't include however is the progress of computer tech which becomes cheaper over time. The comment about inflation is valid, and $50 seems reasonable. The more expensive models are the result of people having increased wishes/expectations, basically using the Pi as a general purpose desktop What's more, 1 and 2GB modules will still likely be fairly cheap since people are moving to higher density mo While obviously it's going to be overhead to that price, it's far from $20 for 4GB. They can leverage quantity, guy them strategically when prices are low (as many manufacturers do), and their purchases don't include a middleman(s) like the ali express ones do.Īll that said, the current spot price for LPDDR4 8Gb modules is ~$2.50. ![]() The pi foundation would have considerable ability to buy them far cheaper in bulk orders direct from the manufacture. What are your thoughts on the rising costs? It's about ensuring that the Raspberry Pi remains a beacon of accessible technology, not just another gadget that only some can afford. ![]() Shouldn't we question when the cost begins to contradict the purpose? I get it, inflation and supply chain issues are real. Are we drifting away from the original vision? Are we okay with this shift towards exclusivity? More importantly, what does this mean for future innovators who might be priced out of experimenting with technology? But now? These prices are a slap in the face to the very community that embraced and championed the Pi. It was a game-changer for hobbyists, educators, and students. I remember the excitement around the Raspberry Pi's debut – a compact, functional computer that won't burn a hole in your wallet. ![]() What on earth is going on with the Raspberry Pi prices soaring above $50? Isn't the whole essence of Raspberry Pi to be an affordable, accessible tool for learning and experimentation? The core principle was to democratize technology, not to create a luxury item! I've got to vent and hopefully shake some sense into this situation. The best thing? The base model is only $20 $5!.ĭo you know a related subreddit? We'd love to know.

![]() While the function is async, the traditional process is synchronous. I thought about it as I was writing my post, but I think synchronous is correct. Requesting multiple lines would need you to build a list of the handles instead of just keeping track of a single handle, and if you're not storing them, then you're probably not guaranteed to keep track of the notecard line order, which probably isn't ideal.Īlternatively, maybe you want to externalize the dataserver event handling to another script to save memory, but then you'll need to communicate that request handle to the other script in some manner, and if I had to guess (without testing) that's going to be hard because of the built-in delay on llGetNotecardLine - by the time you can know the key to send it, the dataserver event on the other script might have already fired, unlike the single-script case where you can be sure the event isn't going to interrupt the currently running one. I have a hard time thinking of particularly great reasons for putting in multiple read requests at the same time though, barring a basic "read multiple notecards sequentially at the same time" situation - get them all started at the same time, process as usual. ![]() The Options are given separated by commas with no spaces between them.Dunno if I'd call the traditonal way "synchronous" since the calls are still fulfilled at a later date, I'd go with "sequential". If nothing is specified, it is understood that all options are linked If you specify any option, it will be understood that it is connected only to informed choices. The height – Specifies the window height in pixels.Īll options (except width and height) are Boolean and can be set in two ways.Įxample: “toolbar” or “toolbar = 1” are the same thing. The width – Specifies the width of the window in pixels The resizable – Allows the user to resize the window The menubar – Creates a menu bar type “File”, “Edit”, etc The scrollbars – Opens vertical and horizontal scroll bars Status – Opens a status bar in the bottom window The directories – Open the toolbar type “What’s New”, “Handbook”, etc The location – Open the browser’s location bar The toolbar – Creates a type of toolbar “Back”, “Forward”, etc Options – These are the options that define the window features, such as:.Window name – is the name that will appear in the window’s top (title). ![]() Url – Internet address where the window opens.Variable – name that will be assigned as property of the window.Variable = window.open (“Url”, “Window Name”, “Options”) ![]() To start working with windows, the general syntax is as follows: The events associated with this object are: onchange, onblur and onfocus.įinally, one of the most common objects in Javascript in interaction are the windows. value: Returns the internal text (value) associated with each option text: returns the external text associated with each option lectedindex: Returns the “index” of the selected object (first = 0).Object.length: Returns the number of existing options in the list.To use this object, it is important knowledge of other associated properties: The only event associated with this object is onclick. This object is a button which aims to submit (send) the contents of the form to the server objects. This object aims to create a button to which to peg logic operations to be performed when it is clicked. The only event associated with these objects is onclick. JAVASCRIPT OBJECT CHECKBOX INPUT AND RADIO The events associated with this object are: onchange, onblur, onfocus and onselect. See following a summary of each of these objects events. Javascript:The user interacting is through objects for data entry (text), dialing options (radio, checkbox and combo), buttons and links to other pages. ![]() However, the lack of a video call option is a significant drawback. It packs quite a punch with its tools, and its channels make it stand out from the crowd. ![]() Telegram is one of the most secure messaging applications out there. There is a web client available for download as well. You’ll find separate, dedicated apps for Android, iOS, Windows, Mac OS X, and Linux. Telegram allows you to synchronise your conversations and channels on all devices. Flexibilityĭesktop and mobile versions of the app exist. Additionally, users can set their account and all associated data to disappear if they don't log in during a certain period. Users can set up Secret Chats with messages that disappear after a determined amount of time. The app is free to use and earns money from donations. Moreover, there is no in-app advertising, and the developers don't share user data with third parties. Its main competition in the field of privacy includes less-known apps such as Threema and Signal Messaging. It features end-to-end encryption and cloud-based messaging. Is Telegram safe?Īnother aspect that sets Telegram apart from its competitors is the amount of security it provides to its users. If you have too many chats, you can organize them into chat folders, and configure the settings as you'd like. Moreover, a catalogue of over 20 thousand stickers by professional artists is available. For example, bots on the app create quizzes and educational tests for anyone to take. Other featuresĪpart from classic messaging and the channels, Telegram boasts other interesting features. Then, you broadcast messages as you would in a private chat. Setting up a channel is straightforward - you give it a name, create a URL, and invite contacts. Alternatively, you can get a link from another user or on online lists on particular websites. The global search function allows you to do so through keywords. You can find channels to follow in three ways. In the latter case, you'll see a verification symbol next to the admin profile. ![]() Most revolve around specific hobbies or topics of interest, but even government bodies sometimes share content using this platform. These can be private or public, and any user can create one. ChannelsĬhannels are one-way messaging platforms where admins can post messages, and an unlimited number of subscribers can access them. Telegram features many photo editing tools for exposure, saturation, blur, curves, and much more. You can send messages and videos through the chat option, too. For personalisation purposes, the app also allows you to use a photo from your device or one of the included images as chat background. The conversation threads are well-designed and easy to follow. The group chats can contain up to 200 thousand people. Telegram allows you to send messages, voice clips, and stickers, to your contacts individually and in groups. You also add a username to your profile, and anyone can find you through this identifier, as well. Since users create their profiles using phone numbers, you'll see all the people whose numbers you have on your phone in your Telegram contacts. Users can find online tutorials for more complex features. Since Telegram hosts more features than its more popular counterparts, it comes with a learning curve. If you already have the app installed and set up on another device, you can perform a quick login with the QR code. When you first open the app, it will require you to register with your cellphone number. ![]() My generator is special, it's a hub motor for an electric bike, with permanent magnets, these motors have torque at low RPM, and operate with BMS controllers that make them work as generator when your bike is going down the hill. Of course the generator power and its optimal rotation speed is also needed to determine the operating point of the wind turbine. As you can see the choice of the right tool for you can be totally different depending on the wind speeds at your location. So in this case the average is not the right tool to use (because of the spread) and even the median seems to be influenced by this heavy spread, only the mode can fit our need. Here we can quickly see that it would be a sharp curve (following a logistic distribution not a normal) with a nice spread on the right (peak on the left, under the average). The skewness (gamma 1) and kurtosis give an idea of the kind of curve of the sample without drawing it. Remove unused columns and roughly estimate the wind speed with a few statistical functions: Average is a well known tool, median is little less known (as many days above as below this figure), and mode shows the most often speed (but we didn't split data in classes yet). ![]() Just open it with OpenOffice Calc (or Excel). Software requirements (to be installed on your computer): Heliciel (proprietary, ) jCAE 0.16 (open source, ) Visorium (french, freeware, ) Autodesk 123D Make (freeware, ) Adobe Reader (version 10 minimum to print posters) If using a scalpel, a cutting mat to make precise and clean cut. Calipers (just to measure some thickness). Fiberglass: Roving 500g / m² and 200g / m², with carbon fiber if possible, or designed for wind turbines ideally Epoxy Resin (laminating epoxy to prevent vapors from polyester and to master drying). Non permanent spray adhesive (in DIY store). Laser cutter or table saw for cutting wood stick (or jigsaw). Laser cutter or brand new scalpel or knife, to cut properly and without compressing cardboard (or scroll saw for MDF). A wood stick of section 30x30mm and 600mm long minimum. Materials needed: Cardboard (or MDF) of the same thickness and in good condition (not pressed or compressed) 594x840mm minimum. If you find this project green, worth a laser cutter, simply useful or beautiful, please vote for it by clicking on the "vote" button at the upper right corner of this page. With all this you're (almost) ready to start manufacturing wind turbines :) My goal is to show that a high tech industrial product can be made with a few tools, limited material and some knowledge (tricks?) and I hope to physically help make this kind of development in some parts of the world where you can't afford to buy such high end products but need them to generate green energy for local community development. After that we'll jump, and backflip like ninjas with file formats to land in 123D Make and finally build this blade. Beware my friend, it's a loooong and detailed instructable since professional wind turbine have many parameters to take in account. Special Parts (Available at the prototype of a wind turbine blade with fiber glass, cardboard, software, tools and affordable or free materials. This exploratory project teaches engineering and modeling and-to make it age- and skill-appropriate-can be scaled up or down in complexity to create more or less electricity, as well as to demonstrate concepts such as energy transformation and blade efficiencies. Learn how to capture the airstream's gusting force with this rugged PVC turbine design by Michael Arquin, founder of the KidWind Project. Over the past few years, wind power has been among the fastest growing sources of energy in the world. Renewable energy is the wind beneath our turbine blades. |
