A Typewriter For The Paperless Age

Writing is, as any of the Hackaday crew will tell you, a task which requires concentration. For your best work there’s a need to be in that elusive Zone, and for some that means making the experience as distraction free as possible. For them there’s an entire class of minimalist word-processors and text editors which reduce the UI to nothing more than the text. [Adam Blumenberg] has taken this a step beyond software with his digital typewriter, a single-purpose Raspberry Pi-based cyberdeck that serves only for distraction-free writing.

There’s not a lot in the way of descriptive text at the above link but in a way there doesn’t need to be as the photographs tell the story. A mechanical keyboard and a wide but not very tall display fit with the Pi in a fairly rudimentary wooden case, and running Focuswriter it leaves very little in the way of distraction. In that sense it’s not quite so much a cyberdeck in its application as something more like the smart digital typewriters from a few decades ago without the printer, but we can see that it makes for a very handy writing implement. Sadly the job of writing for Hackaday requires constant access to online sources on a larger screen, or we’d be tempted to try one ourselves.

The one-purpose writing computer is an idea we’ve seen before from time to time, for example in this one with an e-paper display.

The Birdy44 Keyboard Is Something To Crow About

The funny thing about keyboard end game is that it usually involves more than one keyboard. Rare is the board that is great for both home and away. Having finished their dactyl build, [RalphCoder13] was looking to build something slimmer and more portable, and the Birdy44 was born.

This hand-wired beauty uses a pair of Waveshare RP2040 Zeros and features a pair of 40mm Cirque track pads that were salvaged from a Steam controller.

As you may have guessed, there are 44 Kailh Chocs that sit underneath a combination of MBK and 3D-printed keycaps. Our favorite part might be the tenting legs, which are optional and connect magnetically.

Part of portability is how you decide to carry the thing. You probably don’t want it naked and loose in your backpack if you can avoid it, right? To that end, he designed a nice little case for the halves. The original plan was to use magnets to hold them in place inside the topless case, but that didn’t work out so well, so he added wide elastic bands to stretch around the case.

Is this still not portable enough for you? Check out this folding split keyboard.

Solar Camera Built From Raspberry Pi

Ever since an impromptu build completed during a two-week COVID-19 quarantine back in 2020, [Will Whang] has been steadily improving his Raspberry Pi solar photography setup. It integrates a lot of cool stuff: multiple sensors, high bandwidth storage, and some serious hardware. This is no junk drawer build either, the current version uses a $2000 USD solar telescope (an LS60M with 200mm lens) and a commercial AZ-GTi mount.

He also moved up somewhat with the imaging devices from the Raspberry Pi camera module he started with to two imaging sensors of his own: the OneInchEye and the StarlightEye, both fully open source. These two sensors feed data into the Raspberry Pi 4 Compute Module, which dumps the raw images into storage.

Because solar imaging is all about capturing a larger number of images, and then processing and picking the sharpest ones, you need speed. Far more than writing to an SD Card. So, the solution [Will] came up with was to build a rather complex system that uses a CF Express to NVME adapter that can keep up, but can be quickly swapped out.

Unfortunately, all of this hard work proved to be in vain when the eclipse came, and it was cloudy in [Wills] area. But there is always another interesting solar event around the corner, and it isn’t going anywhere for a few million years. [Will] is already looking at how to upgrade the system again with the new possibilities the Raspberry Pi 5 offers.

Why The RP1 Is The Most Important Product Raspberry Pi Have Ever Made

We’ve had about a week to digest the pending arrival of the Raspberry Pi 5, and it’s safe to say that the new board from Cambridge has produced quite some excitement with its enhanced specifications and a few new capabilities not seen in its predecessors. When it goes on general sale we expect that it will power a slew of impressive projects in these pages, and we look forward with keen anticipation to its companion Compute Module 5, and we sincerely hope eventually a Raspberry Pi 500 all-in-one. It’s the latest in a line of incrementally-upgraded single board computers from the company, but we think it conceals something of much greater importance than the improvements that marked previous generations. Where do we think the secret sauce lies in the Pi 5? In the RP1 all-in-one PCIe peripheral chip of course, the chip which provides most of the interfacing on the new board.

Even 3D Printers Are Taking Selfies Now

We love watching 3D prints magically grow, through the power of timelapse videos. These are easier to make than ever, due in no small part to a vibrant community that’s continuously refining tools such as Octolapse. Most people are using some camera they can connect to a Raspberry Pi, namely a USB webcam or CSI camera module. A DSLR would arguably take better pictures, but they can be difficult to control, and their high resolution images are tougher for the Pi to encode.

If you’re anything like us, you’ve got a box or drawer full of devices that can take nearly as high-quality images as a DSLR, some cast-off mobile phones. Oh, that pile of “solutions looking for a problem” may have just found one! [Matt@JemRise] sure has, and in the video after the break, you can see how not one but four mobile phones are put to work.

Debian Bookworm Comes To The Raspberry Pi, And Wayland Is Now Default

It must have been a busy week for the PR department at Raspberry Pi, with the launch of their latest single-board computer, the Pi 5. Alongside the new board comes something else, an updated Raspberry Pi OS version.

This is built from Debian 12 “Bookworm”, and supplants the previous “Bullseye” version. As well as the new OS base it comes with a pile of Pi-specific upgrades including an optimsied version of Mozilla Firefox. Probably most important is that henceforth (at least on 64-bit boards) its desktop will use the Wayland compositor rather than X11 to draw and manipulate windows. This is a development that has been in the works for a very long time — it must be almost a decade since the first Raspberry Pi blog entry about Wayland — so it’s welcome at last to see it.

The new tweaks as well as Wayland are supposed to deliver a much faster Pi experience, so we thought we’d break out the stopwatch and do some rough real-world tests. The bench 8GB Pi 4 here has a vanilla 64-bit Bullseye installed, so off we went to measure boot time, Chromium browser opening time, and Hackaday load time. It was time to download the new 64-bit Bookworm image and do the same. Have we just downloaded a power-up?

Both tests were done with an everyday boot, after the first-time OS set-up, and with all browser caches emptied. First up was a significant boost, with Bookworm booting in 37.14 seconds to Bullseye’s 53.5, but the Chromium opening was a little more disappointing. On Bullseye it took 7.15s, while Bookworm’s Chromium managed a more pedestrian 9.13s. The new Firefox takes only 7.95s to open. Both Chromium browsers load Hackaday in about 1.8s, while the new Firefox did the same job in a shade over 3s.

So allowing for our stopwatch reaction time and the ad-hoc nature of the test, this is a faster-booting OS, but the underlying hardware is still the limiting factor. We’re disappointed to see that there’s no update for the x86 version of the Raspberry Pi Desktop, and we hope they’ll be able to rectify this in the future.

Dial Up A Tune On The Jukephone

What do you do when you find a nice corded phone with giant buttons out in the wild? You could pay $80/month for a landline, use a VOIP or Bluetooth solution instead, or do something a million times cooler and turn it into a jukebox.

Now when the receiver is lifted, [Turi] hears music instead of a dial tone or a voice on the other end. But playback isn’t limited to the handset — there’s a headphone jack around back.

To listen to a track, he can either dial one in directly, or call up a random track using one of the smaller buttons below. A handy directory organizes the tunes by the hundreds, putting children’s tracks between 1-99 and the intriguing category “hits” between 900-999.

The phone’s new guts are commanded by a Raspberry Pi Pico, which is a great choice for handling the key matrix plus the rest of the buttons. As you may have guessed, there’s an DF Player Mini mp3 player that reads the tracks from an SD card. Everything is powered by a rechargeable 18650 battery.

Jukephone is open source, and you’ll find more pictures on [Turi]’s blog post. Be sure to check out the very brief build and demo video after the break.
