Raspberry Pi Water Cooling Kit is weird, cute, and probably overkill

Posted on by

While 3D printing blasted open the doors for creatives to bring their designs to life, the Raspberry Pi can be credited for empowering not just makers and modders but also a younger generation of budding engineers and scientists by giving them access to a cheap, small yet powerful computer. The single-board computer or SBC has become the basis for many electronics projects and DIY solutions, ranging from smart home security systems to out-of-this-world “cyberdeck” computers. The Raspberry Pi 5, the latest and so far most powerful model available, does have certain performance limits, but you can overclock its processor to really squeeze out all that you can, at the expense of overheating the board, of course. The tiny computer will then need some cooling system, but this particular kit tries to take lessons learned from desktop PCs and apply them in an effective but honestly comical manner.

Water cooling is a well-known solution used in desktop computers to prevent the system from overheating while keeping the processor operating at maximum efficiency. Of course, water doesn’t actually touch the sensitive electronics but draws heat away instead. Cool water travels toward the hotter areas while the heated water travels away from the hot spots and gets cooled by something like a fan. Given the space required to safely and effectively implement it, it’s no surprise that this system is usually only found on large desktop towers.

Compared to those gargantuan computers, the Raspberry Pi only has a fraction of the power but it can still be pushed to the limit by overclocking its CPU. The most common solutions in the market are small heat sinks and tiny fans that provide passive and active cooling, respectively, but some might feel that those just aren’t enough. For really power-hungry setups, this water cooling kit made especially for the Raspberry Pi 5 will probably suffice, if not actually excessive.

The Water Cooling Kit is easily more than five times the size of the small board computer, composed of a water tank and a large fan that cools down the hot water. This contraption is connected to a Raspberry Pi via two silicone hoses, one for hot water and another for cool water, with a radiator sitting on top of the Raspberry Pi’s processor. This kit supposedly halves the temperature of an overclocked Raspberry Pi 5 down to a toasty 37C, depending on the load.

But, yes, you will have to sacrifice a lot to have such a water-cooled Raspberry Pi, starting with the $120 price tag. While the kit can work with multiple Raspberry Pi boards to maximize the cooling efficiency, you’ll have to buy the extra hoses and radiators to make that work. You also definitely lose the Raspberry Pi’s biggest benefit, its small form factor that allows it to be used in almost any project imaginable. Then again, some of those projects do require pushing the small computer to its limit, at which point you might need something over-the-top like this.

Analog digital hybrid clock presses the snooze button for you

One of the biggest struggles I have every morning is the constant battle between me and my smartphone’s alarm clock. I set alarms every 30 minutes for a period of 2-3 hours but more often than not, I still hit the snooze button so all my alarms run into each other. I’ve tried putting my phone away from me so I am forced to get up if I want to snooze it but that only results in me being in a horrible mood. But if i want a more convenient way to snooze (and lose), then this new kind of alarm clock may be what I need.

The Self-Snoozing Alarm Clock may become your best friend or your worst enemy, depending on how you actually look at the snooze button. Instead of having to snooze the device yourself, it actually comes with a hand to snooze itself. It’s a device that uses a fusion of analog and digital and is powered by the Raspberry Pi compact computer module to help you beat the snooze button or actually fall victim to it.

The alarm clock looks like your typical analog clock with its rectangular box but with a digital clock showing on the screen. It is connected to a servo or an actuator that is able to push parts of the device with precision. The mechanism enables this tiny hand to extend from the clock and manually press the snooze button which will then activate the system to keep snoozing until you actually stop it.

If you have an appointment that you need to get to, then this may not be the best alarm clock to have beside you as it will keep you snoozing indefinitely. But it does help you in a sense that you don’t have to be the one to push the snooze button on your phone, although that may not be the best thing if you really think about it.
