The next generation of Wi-Fi has been trickling out over the past year, but this week, its launch is going to accelerate. The Wi-Fi Alliance, the organization that oversees implementation of the Wi-Fi standard, is launching its official Wi-Fi 6 certification program. That might sound boring, but it means the Wi-Fi 6 standard is truly ready to go, and tech companies will soon be able to advertise their products — mostly brand new ones — as certified to properly support Wi-Fi 6.

Use a multiplexer IC to break out four GPIO pins into 16 outputs. Perfect for an ATtiny project!
Ever needed to control many outputs but didn’t have enough GPIO pins? What about using 16 LEDs with only 5 pins? This is where a multiplexer is useful.
Researchers at MIT and elsewhere have created a 3D printing process that produces objects with the electronics already embedded inside.
The process uses customized fused deposition modeling (FDM) printers, but instead of melting the entire filament, only the outer polymer cladding is liquefied, leaving an internal electronics structure unaffected.
How to make awesome epoxy model from 3D print.
What You need: –
3D printed model –
liquid silicone rubber –
2 component epoxy resin
I don’t generally pay much attention to Intel-based boards. There have been the odd exceptions, but usually run too hot, and are just too expensive, to be particularly interesting. But it looks like there might soon be one more board added to the short stack of exceptions, the new Rock Pi X.
Learn more about the new experience for Nintendo Switch, coming October 18th!
It’s perhaps a bit surprising how many Raspberry Pi boards have made it to space. Totally ignoring all the Raspberry Pi boards that make it into space the cheap and cheerful way on a high-altitude balloon, there are at least two aboard the International Space Station in use by the astronauts, and another two running cryptography experiments for ESA.
There are others, but they were joined in July by yet another Raspberry Pi that was carried to orbit by a Russian Soyuz-2–1b Fregat-M rocket into a solar synchronous orbit.
Klipper is a special firmware designed to perform the heavy lifting of calculating kinematics on a Raspberry Pi and therefore simplify the job of the existing 3D printer mainboard. This allows very precise stepper motor timing and potentially much higher speeds.
In this installment, I swap the Ender 3 mainboard for an MKS Gen L and setup TMC2208s in UART mode, the LCD, and hot end activated fan. It wasn’t easy so the config file is provided below. TMC2208s are notorious for not getting along well with Klipper, especially in stand alone mode.
PinkyPi X is now available for download on Thingiverse.com. This is based around the WaveShare GamePi15 game hat and a RaspberryPi Zero.
As always, the original Sketchup source files I created when designing this case have been included.
You can also download our precompiled RetroPie 4.5.1 image from our Downloads.
This image has preconfigured controls, and utilizes the fbcp-ili9341 display driver and PiSNES for the best available speeds you can get on a Pi Zero.
If you like the work we do, and would like to support us, please consider a one time or reoccurring donation to our new Patreon we are setting up.
You can also follow along in the build and join in the conversation on our forums in the PinkyPi X thread.
At VMworld, various cool new technologies were previewed. In this series of articles, I will write about some of those previewed technologies. Unfortunately, I can’t cover them all as there are simply too many. This article is about ESXi on ARM, which was session OCTO2944BU. For those who want to see the session, you can find it here. This session was presented by Andrei Warkentin and Daniel Beveridge. Please note that this is a summary of a session which is discussing a tech preview, these features may never be released, and this preview does not represent a commitment of any kind, and this feature (or it’s functionality) is subject to change. Now let’s dive into it, what is VMware doing with ARM?
