Humans have come up with a lot of ways to display the time over the centuries that we’ve been bothering to do so. In the late ‘70s and early ‘80s, digital LCD clocks and wristwatches were all the rage as people got excited about the cool new technology. These days, analog clocks are seen as classier than their digital counterparts. It’s also possible to mesh the two together into kinetic works of art. That’s what Erich Styger has achieved with his Meta Clock that is made of 24 individual analog clocks.
This video shows how to integrate a torrent seedbox with your media server. It shows how to setup the seed box then use it with a combination of sonarr, radarr and syncthing. In this video setup is on an Unraid server but this can be done on any system using the 3 above applications.
Something to look forward to: Intel is offering an appealing upgrade with their tenth generation of mainstream processors. Every CPU now has hyperthreading, and every CPU is getting a 100-200 MHz speed bump over its predecessor. The flagship i9-10900K is also getting two extra cores and a new boost mode that can push speeds up to 5.3 GHz.
Everybody is crazy about LED cubes. I wanted to create one myself, but I wanted to make it an even bigger challenge and since I am not limited by the use of circuit boards and can make it free-form. I’ve decided to make an LED ball. I believe this is the first instance of air-wire LED ball in the world.
It’s controlled by ESP32 board and powered by 1000mAh LiPo battery. So not only it is wearable but also can be controlled via mobile phone.
In this episode, I’ll show you how to build your own DIY NHL scoreboard that automatically displays live game data for your favorite hockey team!
The purpose of this video is not only to combine hockey and technology, but to teach you how to work with and control LED panels using a Raspberry Pi computer. Armed with this knowledge, you can create all kinds of displays. 🙂 This is a very easy, mostly plug-and-play project that takes less than an hour to complete.
We’re all used to the humble LED as a ubiquitous source of light, but how many of us are aware that these components can also be used as photodiodes? It’s something [Giovanni Blu Mitolo] takes us through as he demonstrates a simple data link using just a pair of LEDs and a couple of Arduinos. It’s a showing off his PJON networking layer, and while you’d need a bit more than a couple of LEDs on breadboards for a real-world application, we still think it’s a neat demonstration.
PJON itself is very much worth a look, being an implementation of a robust and error-tolerant network for Arduinos and other small microcontroller platforms. It has a variety of communication strategies for various different media, and as this LED demonstration shows, its strength is that it’s capable of working through media that other networks would balk at. Whether it’s controlling home automation through metal heating ducts or providing an alternative to LoRa at 433 MHz, it’s definitely worth a second look. We’ve mentioned it before, but remain surprised that we haven’t seen it more often since. Take a look, the video is below the break.
Scientists at the University of Tokyo’s Shinoda & Makino Lab have designed an ultrasound phased array capable of changing the trajectory of a ping pong ball (PPB) in flight. While that doesn’t sound too interesting, the device has potential in many applications, including removing defective samples in food production, used in augmented sports, and changing the direction of an object thrown by humans, among a host of others.
I love going out for a ride on my bicycles, and I got tired of replacing the speedometer, so I decided to build one. I have the old reed switch and magnet from the last one, and I’m going to use it to get the reading. In this episode I show you how I connected to it, run a test to make sure it still working.
