The article describes its firmware and server customization, tile-based display service, Liquid templating, and a Go program on Cloud Run that displays family calendar events. It also notes refresh-scheduling difficulties and the device's relatively high cost. ### Source excerpt The TRMNL is an 800x600, 1-bit e-ink display connected to a battery and a microcontroller, all housed in a nice but unremarkable plastic case. Because the microcontroller spends the vast majority of the time sleeping, and because e-ink displays don't require power unless they're updating, the battery can last six or more months. It charges over USB-C. When the microcontroller wakes up, it connects to a Wi-Fi network and communicates with a pre-configured server to fetch an 800x600 image to display, and the duration of the next sleep. You can flash your own firmware on the device, or point the standard firmware at a custom server. The company provides an example server, although you can implement the (HTTP-based) protocol in whatever way you wish. I considered running my own server, but thought I would give the easy path a try first to see if it would suffice. The default service lets you split the display into several tiles, and there are a number of pre-built and community-built things that can display in each. None of them worked well for me, but that's okay because you can create your own private ones. They get data either by polling a given URL, or by having data posted to a webhook. The layout is rendered using the Liquid templating system, which I had not used before, but it's reasonably straightforward. I wrote a Go program hosted on Cloud Run which fetches the family shared calendar and converts events from the next week into a JSON format designed to make it trivial to render in the templating system. With a 3D-printed holder, super glue, and some magnets, it's now happily stuck to the fridge where it displays the current date and the family events for the next week. The most awkward part of the default service is managing the refreshes. The device has a sleep schedule, and so do the tiles, which are only updated periodically. So the combination can easily leave the wrong day showing. It would be helpful if the service told you when the device would next up ## Introducing the PineNote DevFeed: [Introducing the PineNote]() Original publisher: [Read original article]() Published: 2021-08-15T00:00:00Z Content type: news Language: en Sources: [Community blog on PINE64]() Topics: [e-ink](), [Single Board Computer](), [Hardware](), [Pinephone]() Tags: [announcements](), [devices](), [e-ink](), [firmware](), [pinedio](), [pinenote](), [pinephone](), [pinetime](), [quartz64](), [release](), [single-board-computer]() ### AI overview PINE64 announces the PineNote, a high-end e-ink device based on the Quartz64 single-board computer, with an RK3566 processor, 4GB of LPDDR4 RAM, 128GB of eMMC storage, a Wacom-compatible panel, and a planned $399 price.

It describes a script that plots FLAC amplitude into a tempo-based grid and discusses clearer patterns in quantized electronic, pop, and rock music, along with a 3D-rendered fantasy record-player experiment. ### Source excerpt Back in April I bought a vinyl record that had a weird wavy pattern near the outer edge. I though I may have broken it somehow but couldn't even test this because I don't own a record player. *) But when I took a closer look at the pattern it seemed to somehow follow changes in the music. That doesn't look like damage at all. When I played the CD version it became clear: this was an artifact of the tempo of the electronic track (100 bpm) being a multiple of the rotational speed (33 1/3 rpm), and these were probably drum hits! My tweet sparked some interesting discussion and I've been pondering this ever since. Could we plot any song as a loop or grid based on its own tempo and see interesting patterns? (*) I know, it's a little odd. But I have a few unplayed vinyl records waiting for the day that I finally have the proper equipment. By the way, the song was Black Pink by RinneRadio from their wonderful album staRRk. I wrote a little script to do just this: to plot the amplitude of the FLAC into a grid with an adjustable width. The result looks very similar to the pattern on the vinyl surface! Note that this image is a "straightened out" version of the disc surface and it's showing three of those wavy patterns. The top edge corresponds to the outer edge of the vinyl. Later I wrote a little more ambitious plotter that shall be explained soon. Computer-conducted music gives best patterns After plotting several different songs against their own tempo like this it seemed that in addition to electronic music a lot of pop and rock has this type of a pattern, too. The most striking and clear patterns can be seen in music that makes use of drum samples in a quantized time base (aka. a drum machine): the same kick drum sample, for example, repeats four times in each bar, perfectly timed by a computer so that they align in phase. Somewhat similar patterns can be seen in live music that is played to a "click track": each band member hears a common computer-generated time signal
