Backstage Backstage #20

New Mac day!

We upgraded to the new MacBook Pro M1 Max and decided to share our first impressions of the new hardware, how we migrate data and settings from our old machines (or don’t), which apps were “instant installs” for each of us, which apps we’re trying to live without, and how we get our new machines set up for work and play. Nerd out with us!

Find the infrastructure advantage

Zac Smith, managing director Equinix Metal, is sharing how Equinix Metal runs the best hardware and networking in the industry, why pairing magical software with the right hardware is the future, and what Open19 means for sustainability in the data centre. Think modular components that slot in (including CPUs), liquid cooling that converts heat into energy, and a few other solutions that minimise the impact on the environment.

But first, Zac tells us about the transition from Packet to Equinix Metal, his reasons for doing what he does, as well as the things that he is really passionate about, such as the most efficient data centres in the world and building for the love of it.

This is a great follow-up to episode 18 because it goes deeper into the reasons that make Gerhard excited about the work that Equinix Metal is doing. This conversation with Zac puts it all into perspective.

By the way, did you know that Equinix stands for Equality in the Internet Exchange?

iFixit tears down the new MacBook Pro

These teardowns are always an enjoyable read. This one is particular interesting because of the large upgrade this year’s line of pro laptops is and how Apple appears to be returning to form with their design decisions. Here’s the lede:

We’ve still got a long way to go with disassembly, but this new MacBook Pro has, at the very least, the first reasonably DIY-friendly battery replacement procedure since 2012.

MagInkCal syncs your Google calendar with a framable e-ink display

This incredibly cool DIY e-ink calendar uses a Raspberry Pi Zero WH to do its thing. Here’s how it works:

Through PiSugar2’s web interface, the onboard RTC can be set to wake and trigger the RPi to boot up daily at a time of your preference. Upon boot, a cronjob on the RPi is triggered to run a Python script that fetches calendar events from Google Calendar for the next few weeks, and formats them into the desired layout before displaying it on the E-Ink display. The RPi then shuts down to conserve battery. The calendar remains displayed on the E-Ink screen, because well, E-Ink…

Open source civilization

This week we’re talking about open source industrial machines. We’re joined by Marcin Jakubowski from Open Source Ecology where they’re developing open source industrial machines that can be made for a fraction of commercial costs, and they’re sharing their designs online for free. The goal is to create an efficient open source economy that increases innovation through open collaboration. We talk about what it takes to build a civilization from scratch, the Open Building Institute and their Eco-Building Toolkit, the right to repair movement, DIY maker culture, and how Marcin plans to build 10,000 micro factories worldwide where anyone can come and make.

Turn your Kindle into a HUD for every day life

David Hamp-Gonsalves created a really cool use for your old Kindle:

Second hand Kindles are waiting in drawers for someone to repurpose them into something great. Boasting large e-ink screens, wifi connectivity and ARM processors they are an amazing hacking platform.

In my case I created an information panel summarizing my day such as my calendar, surf and weather forecast, garbage schedule, school closures, etc. My favorite part is that any extra space is filled with a random Pokémon sprite which my kids(not me) like to come check in on.

Built with Rust plus some serverless backend data collection bits.

Building a deep learning workstation

What’s it like to try and build your own deep learning workstation? Is it worth it in terms of money, effort, and maintenance? Then once built, what’s the best way to utilize it? Chris and Daniel dig into questions today as they talk about Daniel’s recent workstation build. He built a workstation for his NLP and Speech work with two GPUs, and it has been serving him well (minus a few things he would change if he did it again).

A $70 desktop Raspberry Pi in a keyboard (!)

You likely already saw this, but I don’t even care because I have to link to it because it is so freakin’ cool!

We’ve never been shy about borrowing a good idea. Which brings us to Raspberry Pi 400: it’s a faster, cooler 4GB Raspberry Pi 4, integrated into a compact keyboard. Priced at just $70 for the computer on its own, or $100 for a ready-to-go kit, if you’re looking for an affordable PC for day-to-day use this is the Raspberry Pi for you.

Creating a Sonos volume knob with Elixir and LiveView

Steven Fuchs loves his Sonos, but…

While it is the radio of the future, our most common usage is as the radio of the past. We tend to tune it to one station and leave it there. By far, our most common interactions with the system are changing the volume and pausing/playing the music, often creating scrambles to find a phone to turn down the volume in order to answer a different phone. What we needed was an analog interface to this digital system that was always at arms reach.

Hackers gonna hack. Steven reached for Elixir and scratched his own itch with this very cool little hardware project. Here’s a demo video of it in action.

PiSight brings back Apple iSight

Max Braun thinks today’s webcams are boring, so he brought back a classic. Max took an Apple iSight and retrofitted it with a $5 Raspberry Pi Zero, which “fits the iSight’s dimensions almost perfectly.”

The PiSight actually works like you’d expect it to. Just plug in the USB cable and the camera will show up in your video conferencing app of choice. The image quality is quite good, possibly better than the built-in camera of today’s MacBooks.

The best part is you can do this too because Max made all the plans available as open source.

Just in case you’re not completely taken aback by the absurdity of this project and are now considering building your very own PiSight, rest assured that I’m making everything available as open source.

The GitHub repo has a list of parts and where to get them, the 3D-print-ready model of the frame, and the source code. I’m thinking it should be possible to get the total cost down to under $150. I had to spend a bit more than that because I needed to experiment and opted for higher-end materials.

The Open Book Project

An ambitious attempt to create an open source device for reading. But why?

As a society, we need an open source device for reading. Books are among the most important documents of our culture, yet the most popular and widespread devices we have for reading — the Kobo, the Nook, the Kindle and even the iPad — are closed devices, operating as small moving parts in a set of giant closed platforms whose owners’ interests are not always aligned with readers’.

It’s still early days, but the project got a boost of support by winning Hackaday’s Take Flight with Feather contest in January.

An open source, drop-in controller for the IKEA Bekant standing desk

OK so maybe you don’t use a standing desk… like I do. OR maybe you do, but you don’t use the IKEA Bekant desk in particular… like I do. STILL you can appreciate how hacker it is that someone built their own drop-in controller to add memory positions to the Bekant… right?

I wanted to have memory positions for easily switching between various work positions. I also didn’t want to be limited to just 2 positions. However, as I went through the process, I realized the hardest part was designing the enclosure. 3D Printing is a great option, but lacks that professional look, and limits the availability to those with printers. Additionally, getting custom membrane buttons that would look good was also extremely expensive. Simple push-buttons would take away from the look of the desk.

By targeting the factory enclosure, it keeps the original look and robustness, while adding functionality.

See it in action right here.

Time to upgrade your monitor

According to my research among programmers, 43% are still using monitors with pixel per inch density less than 150…

Why is this a problem? Because the only way to get good letters is by spending more pixels per letter. That simple. In the past, the displays’ pixel count was small, so we learned to live with that and even invented some very clever tricks to make our lives better.

Nikita goes on to share more details of how text looks on a low-resolution display vs a retina display. I’d love to see a follow up poll of the 43% using 150 PPI or less monitors on “why” they haven’t made the move to retina yet.
