News for hackers. Stuff that matters.

I suspect you can fix that by adding a level shifter between the display and the ESP32. Input voltage thresholds are relative to the voltage rail, which is why reducing the display's voltage relative to the ESP32's (3.3v) outputs make it able to read the data.
There’s one incoming, https://baochip.github.io/baochip-1x/ It would be great to see more.
Re:Remarkable Pro Colors on Wednesday February 04, 2026 @08:49PM (#46894589)
Is that true on the pro? I trialed one maybe a year ago and got the impression that the company had stopped supporting third party devs.
I had a hang that sounds similar to yours the other day, and it appeared to retrain on the next boot. Does that line up with what you've seen?
I agree, the input devices leave something to be desired. I dream of grafting a MBP keyboard and trackpad onto my FW13.

It's plausible that broad concern about recycled plastics would be valid.

This study[1] found that the recycled plastics analyzed were fairly toxic. I recall another that found the same for recycled synthetic clothing, but I was unable to find a reference.

Re:Raspberry Pi 5 on Thursday September 28, 2023 @03:10PM (#37694200)
That doesn't fit the bill:

> Output voltage (four charging modes): PDO DC5.0V-3.0A or 9.0V-2.77A PPS 3.3-5.9V-3A or 3.3-11.0V-2.24A

5V output at 5A is pretty unusual.

I'm a Boox device owner and can confirm they declined my request for the GPL source code.
I enjoy this simply to have sunset, sunrise, and moon phase on my wrist. The added precision from the finetune watch face is a nice bonus.
How does this compare with Fermyon's WebAssembly platform?
I love this idea! Thanks for sharing, I'm looking forward to trying this out day to day.
I wrote a server that bridges Subsonic clients to my Spotify library. I like that it lets me to stream anything on Spotify but I can still fill in favorites that aren't available.

This appears to share lineage with Umbrel. I haven't looked deeply enough to make any particular claims, but I feel fairly confident that one of these projects is violating someone's copyright.

For an example, compare https://github.com/meienberger/runtipi/blob/master/scripts/a... with https://github.com/getumbrel/umbrel/blob/master/scripts/app.

Re:Casio F91 smart watch reboot on Friday July 22, 2022 @12:11AM (#32188434)
I suspect they're referring to the more recent Sensor Watch: https://www.crowdsupply.com/oddly-specific-objects/sensor-wa...

Quick review: I have one of the early units and I've really enjoyed using it. It's totally hackable, well documented, and I fully anticipate using mine for the next decade or longer. It's far from a smartwatch - it's more like you're sitting in on the Casio product meeting where they wrote the original F-91W specs. The year-scale battery life remains, but it comes with the ability to fully customize the watch behavior. For me, that meant adding sunrise/sunset and moon phase faces. I might build a quick-timezone switcher in the future.

Re:Firefly III: A free and open-source finance manager on Monday May 30, 2022 @10:39PM (#31565605)
Firefly III has a documented API [1] that can be used to build import tools. I used it to build a Plaid importer [2].

As a current candidate, I'd be interested in hearing more about your interview experience.

Re:Ask HN: Do you keep a personal knowledge repository? on Saturday May 25, 2019 @01:25AM (#20007280)
I use BookStack (https://www.bookstackapp.com). MIT licensed & easy to self host.

It's fast and has good search, a good editor, and uses simple hierarchical organization + tagging. I like that it gets out of my way and does a good job of handling everything from code snippets to freeform thoughts to recipes.

BookStack is best for things that 'look like' documents. Mobile editing could also be better - you have to click a maximize button to get a usable view of the editor and the editor UI still takes up a lot of space. It is web based, but it is very lightweight and I have found it very easy to host.

Re:Brand New ODroid Single Board Computer on Saturday October 20, 2018 @01:03AM (#18261848)
I could see this being a great home server - it could easily run NAS, Plex, a firewall, and some misc containers. It may be a cheaper option for robotics projects that don't need the compute ability of a NVidia Jetson.

Pretty awesome board:

- Intel J4105 (2.3Ghz Quad-core, fanless!)

- Up to 32GB DDR4

- M.2 SSD (4 x PCIe 2.0)

- 2 x GbE

- 2 x SATA 3.0

- HDMI 2.0 and DP 1.2 at 4k

- 2xUART, 2xI2C - both at 3.3V

- 110x110x43mm

- Expected to ship in late November, price will be above $100

Snapcast would likely work better for this use case - it handles audio endpoint synchronization.
