Wi-Fi 7: The Next Big Leap Or A Whole Lotta Nothing?

For most people, the Wi-Fi hardware of today provides a perfectly satisfactory user experience. However, technology is ever-evolving, and as always, the next advancement is already around the corner. Enter Wi-Fi 7: a new standard that is set to redefine the boundaries of speed, efficiency, and connection reliability.

Wi-Fi 7 isn’t just another incremental step in the world of wireless tech. It’s promising drastic improvements over its predecessors. But what does it bring to the table? And how does it differ from Wi-Fi 6E, which is still relatively fresh in the market? Read on.

Atari Introduces A New Old Console

September 11, 2023 by Tom Nardi 29 Comments

Readers of a certain age no doubt remember the Atari 2600 — released in 1977, the 8-bit system helped establish the ground rules for gaming consoles as we know them today, all while sporting a swanky faux wood front panel designed to make the system look at home in contemporary living rooms.

Now, nearly 50 years later, the Atari 2600 is back. The new system, imaginatively named the 2600+, looks exactly like the original system, albeit at around 80% scale. It will also work the same way, as the system will actually be able to play original Atari 2600 and 7800 cartridges. This is something of a surprise when compared to the previously released retro consoles from the likes of Sony and Nintendo, as they were all limited to whatever games the company decided to pack into them. Of course, this probably has something to do with the fact that Atari has been selling newly manufactured 2600 games for some time now.

Although it will play original cartridges, it’s still an emulated console at heart. There aren’t a lot of technical details on the product page, but it does say the 2600+ is powered by a Rockchip 3128 SoC with 256 MB of DDR3 RAM and 256 MB eMMC flash. Some quick searching shows this to be a pretty common board for set-top gadgets, and wildly overpowered considering the meager requirements for emulating a game console from 1977. We wouldn’t be surprised to find it’s running some kind of minimal Linux install and using one of the existing open source emulators.

While the 2600+ sports the same 9-pin D-sub controller connectors as the original console, it thankfully embraces modern display technology and outputs over HDMI. Each console will come with a “10-in-1” cartridge that contains some of the console’s most popular titles, as well as a modernized version of the original single-button joystick. (Unlike the original, the 2600+ comes with only a single joystick — the other is sold separately.)

Atari won’t start shipping the 2600+ until this fall, but they’re currently taking preorders for the $130 system. We’re eager to see somebody pull it apart, as the earlier “mini” consoles ended up being ripe for hacking.

Bringing Da Vinci’s Saw Mill To Life

September 11, 2023 by Al Williams 30 Comments

DaVinci’s notebook — the real one, not the band — was full of wonderous inventions, though many were not actually built and probably weren’t even practical with the materials available at the time (or even now). [How To Make Everything] took one of the Master’s drawings from 1478 of a sawmill and tried to replicate it. How did he do? You can see for yourself in the video below.

There are five different pieces involved. A support structure holds a water wheel and a saw. There’s a crank mechanism to drive the saw and a sled to move the wood through the machine. It sounds simple enough, although we were impressed and amused that he made his own nails to be authentic. No Home Depot back in the 1470s, after all.

Watching him produce, for example, castle joints, makes us think, “Hey, we could do that!” But, of course, we probably can’t, at least not by hand. We must admit we are pretty dependent on CNC tools and 3D printing, but we admire the woodwork, nevertheless. There’s some pretty cool metal working, too.

We thought the waterwheel would be the easy part, but it turned out to be a bit of a problem. Things worked, but it was slower than you would think. We’ve seen sawmills put together before. Da Vinci worked for money, and there was always money in weapons so he did design a lot of them, too.
