PS5 Goes On Slim-Fast

For the past few decades, most console makers have first come out with a large flagship model, and then a few years later, released a smaller, more compact slim edition. Not content to wait for it, [Matt] at DIY Perks made his own PS5 Slim, and the results are awe-inspiring.

Generally, slim editions are made by lowering the TDP of the chip under the hood. A lower power draw means less cooling is needed, a smaller power supply can be used, and a design that is overall easier to manage. Unfortunately, [Matt] had none of these benefits and instead had to contend with the full 180 W that the AMD CPU inside the PlayStation can draw.

Taking apart the console left him with the main board that was quite thick as it had heat pipes on both sides. His first thought was water cooling as it can rapidly move the heat needed, but even with right-angle fittings, it didn’t fit within the ambitious thickness goal he had set for himself of less than 2 cm (about 3/4″). To do that, [Matt] had to fabricate a copper water block from three sheets of copper. The first one connects to the motherboard via standoffs and has cut-outs for various connectors and parts. The middle layer has a channel through which water can flow, and the last layer seals it together.

With the three layers together, he soldered them in a toaster oven repurposed as a reflow oven. Cleverly, he used silicone grease to prevent solder from getting into areas he didn’t want, like the fins in the CPU block. Luckily, the grease dissolved in alcohol, and after flushing the chamber, he had a solid copper, water-tight, custom loop.  However, on his road to glory, [Matt] ran into a snag. He accidentally covered the intake vent on the radiator, and the PS5 overheated, killing it. With a fried mainboard and a project almost on the cusp of completion, he resorted to using the PS5 he had received for B-roll.

Last-minute motherboard swap aside, the final project is gorgeous. The polished exterior and sheer thinness of it are striking. [Matt] has already disguised his PS5 before and after this, we’re not quite sure where he could possibly take it next. But we’re excited to find out.

Sexiest Tiny Metal Core-XY 3D Printer

That’s a lot of qualifications, but we’re pretty sure that you can’t accuse us of hyperbole in the title: this is one of the tightest little 3D printer builds we’ve ever seen. Add in the slightly esoteric CoreXY kinematics and the thick aluminum frame, and it’s a speed demon in addition to being a looker.

[René] had built a few 3D printers before, so he had a good feel for the parameters and design tradeoffs before he embarked on the DICE project. Making a small print volume, for instance, means that the frame can be smaller and thus exponentially more rigid. This means that it’s capable of very fast movements — 833 mm/s is no joke! It also looks to make very precise little prints. What could make it even more awesome? Water-cooled stepper motors, magnetic interchangeable printheads, and in-built lighting.

The build looks amazing, and there is video documentation of the whole thing on [René]’s site, including a full bill of materials and designs. It’s certainly not the cheapest 3D printer we’ve ever seen, and the tiny build platform makes it a bad choice for a general-purpose machine, but if you need a second printer and you want one with style, the DICE looks hard to beat.

A Watercooled Headlamp, Because Why Not?

There are extremely high powered LEDs out there, and most of the ‘creative’ uses of these are extremely high-powered flashlights, complete with heatsinks, forced air cooling, and beefy power supplies. [Christian] wanted to play around with one of these LEDs, but he wanted something a little more unique. He chose a headlamp, a build that is made even more impressive by the fact it is watercooled.

The body of the headlamp was milled out of aluminum, with a space for the LED in the front and channels in the back for coolant. Also in this enclosure are two buttons, a temperature sensor, and a port for the hose that carries the tubes and wires.

This hose connects to a large battery pack that houses four large lithium phosphate batteries and a boost converter built around an Arduino. The pack also houses a pump and reservoir that is able to keep the LED cool even at 130W.
