By now most floppy disks have been relegated to the dustbin of history, with a few exceptions for obscure industrial applications using legacy hardware and, of course, much of the world’s nuclear weapons arsenals. In fact, they’re so rare to see in the world anymore that many below a certain age don’t recognize the “save” […]
Your design task, should you decide to accept it: given an input voltage, square it. Ok, that’s too hard since squaring 8 volts would give you 64 volts, so let’s say the output should be 10% of the square, so 8 volts in would result in 6.4V. How do you do it? [Engineering Prof.] knows […]
As it stands, cryptocurrency largely seems to be a fad of the previous decade, at least as far as technology goes. During that time, many PC users couldn’t get reasonably priced graphics cards since most of them were going into these miners. In contrast, nowadays any shortages are because they’re being used to turn the […]

However, the vast majority of these components are made out of plastic and are only capable of toy-like levels of performance. In the competitive world of Lego YouTube, builders often push these parts to their limits, […]

In the video, the presenter explains the service loop serves two purposes: on the one hand it may provide strain relief, but chiefly these loops are installed so there will be extra available slack in the cable if you need to […]
There comes a time in any software developer’s life when they look at their achievements, the lines of code written and the programming languages they have relied on, before wondering whether there may be more out there. A programming language and its associated toolchains begin to feel like familiar, well-used tools after you use them […]
People have been coming up with clever ways to bring light to the darkness since we lived in caves, so it’s no surprise we still love finding interesting ways to illuminate our world. [Michael] designed a simple, but beautiful, book lamp that’s easy to assemble yourself. This build really outshines its origins as an assembly […]
There are all manner of musical myths, covering tones and melodies that have effects ranging from the profound to the supernatural. The Pied Piper, for example, or the infamous “brown note.” But what about a song that could crash your laptop just by playing it? Even better, a song that could crash nearby laptops in […]
It’s been awhile since we checked in with Canada’s Edison Motors, so let’s visit [DeBoss Garage] for an update video. To recap, Edison Motors is a Canadian company building diesel-electric hybrid semi-trucks and more. The last interesting thing to happen in Donald, BC was when it burned down in the 1910s. Well, they’ve thankfully moved […]
With immunotherapy increasingly making it out of the lab and into hospitals as a viable way to treat serious conditions like cancer, there’s a lot of pressure to optimize these therapies. This is especially true for therapies involving chimeric antigen receptor (CAR) T cells, which so far required a cumbersome process of extracting the patient’s […]
