***NOW AVAILABLE*** Improved versions of these limit switches, on professionally-made PCBs, are now available for purchase on my Tindie store, with wiring and neodymium magnets optionally included!
https://www.tindie.com/products/kevpatt/creltek-limit-sensor-343rt/I also have professionally-made breakout boards for both sensor and stepper motor wiring, suitable for panel-mounting. Check out these items and more, here:
https://www.tindie.com/search/#q=CreltekHere's some information about a set of custom limit switches I made for my Shapeoko 2.
The limit switches are built on small PCBs with a hall-effect sensor as the active element. The hall-effect IC senses the proximity of a suitably oriented magnetic field, and closes the switch circuit when the magnet is close by.
I included a small bi-color LED (along with other miscellaneous support components) to give a visual indication of state. "Green" indicates that the limit switch is powered and ready. "Red" indicates that the switch has been triggered.
The switches are activated by small neodymium magnets that are mounted on the moving portions of the machine. The magnets are positioned so that the switches are triggered at a practical extreme axis position (with an appropriate safety margin, of course.)
The switches themselves are attached to the Shapeoko using small machine screws (into holes that I tapped, where needed).
The switches are wired to a TinyG motion controller using standard "flat" 4-conductor telephone cord. I was able to run this easily through various channels in the Shapeoko and keep things looking neat. The cords terminate with standard RJ-11 telephone plugs, which are plugged into a gang of RJ-11 jacks on a custom breakout PCB that I made. At some point in the future the TinyG, along with the power supplies and breakout boards, will be mounted in a suitable enclosure. (Right now they're screwed to a nearby wall stud under my basement stairs.)
About the Site 🌐
This site provides links to random videos hosted at YouTube, with the emphasis on random. 🎥
Origins of the Idea 🌱
The original idea for this site stemmed from the need to benchmark the popularity of a video against the general population of YouTube videos. 🧠
Challenges Faced 🤔
Obtaining a large sample of videos was crucial for accurate ranking, but YouTube lacks a direct method to gather random video IDs.
Even searching for random strings on YouTube doesn't yield truly random results, complicating the process further. 🔍
Creating Truly Random Links 🛠️
The YouTube API offers additional functions enabling the discovery of more random videos. Through inventive techniques and a touch of space-time manipulation, we've achieved a process yielding nearly 100% random links to YouTube videos.
About YouTube 📺
YouTube, an American video-sharing website based in San Bruno, California, offers a diverse range of user-generated and corporate media content. 🌟
Content and Users 🎵
Users can upload, view, rate, share, and comment on videos, with content spanning video clips, music videos, live streams, and more.
While most content is uploaded by individuals, media corporations like CBS and the BBC also contribute. Unregistered users can watch videos, while registered users enjoy additional privileges such as uploading unlimited videos and adding comments.
Monetization and Impact 🤑
YouTube and creators earn revenue through Google AdSense, with most videos free to view. Premium channels and subscription services like YouTube Music and YouTube Premium offer ad-free streaming.
As of February 2017, over 400 hours of content were uploaded to YouTube every minute, with the site ranking as the second-most popular globally. By May 2019, this figure exceeded 500 hours per minute. 📈
