    Improve Volume Wheel Daemon (Bounty!)

    I just remembered... the OMAP5432 CPU in the Pyra contains (same as with the AM335x) two fully-programmable Cortex M4 microcontrollers: I wonder if they're able to handle polling of the volume wheel ADC in the background... and then...

    Should I have received my final order eMail already?

    Does xrandr work? For example: $ xrandr $ xrandr --output HDMI1 --mode 1920x1080 --same-as LVDS1 $ xrandr --output HDMI1 --mode 2560x1440 --right-of LVDS1 $ xrandr --output HDMI1 --mode 2560x1440 --above LVDS1

    Everything sorted into the shelves

    Exactly what kind of parts are affected by the shortages? The CPU or RAM? Or is it trivial stuff like SMD capacitors? I would be interested to know this, once you know this yourself. Thanks!

    Improve Volume Wheel Daemon (Bounty!)

    Then please, next time, describe in your post what the code does! Don't assume we can all immediately see that from reading the code. Can you be more specific? It sucked because it was too slow to respond to changes? Because it made the code unnecessarily complex? Because it used too much CPU...

    Improve Volume Wheel Daemon (Bounty!)

    It's important to note that the poti has end stops (it can only turns some limited amount in each direction). An advantage is, at suspend/resume, or a reboot, the poti remembers its absolute position. And you can feel with your fingers when you've reached the minimum/maximum. A disadvantage is...

    Brief Answers to the Big (Pyra) Questions

    If U-Boot could detect this situation, it could boot an alternate system that goes into a low-power mode (turn off display or peripherals), indicates the level of charge somehow (e.g. with LEDs, or on-screen after a button press) and upon pressing the power button, reboots into the real OS. Most...

    My first impressions of the Pyra

    If Audacity is working already on the Pyra that would be another good way to test audio. Would be also interesting to play a sine wave from the left speaker at the same time as the *inverted* signal from the right speaker. If both channels are played correctly, you would notice weird phase...

    Using the Pyra as a web server and phone simultaneously

    There are definitely a lot of people interested in running decentralized/federated services like blogs, chat, email, OwnCloud on their own hardware. If your cell plan doesn't include an IPv4 address (most don't), then you may need to rent one somehow and set up a VPN tunnel so that the...

    well, it's not their fault if they have to collect UK VAT on goods from the EU now, is it!

    Are you interested in a new Pandora LCD cable?

    Generate QR codes on the screen, read them with a webcam/smartphone which saves them to a file (or even stops/pauses the test when no code has been read for X seconds)? * include a counter or timer in the QR code * reduce the number of error correction blocks when generating the QR code *...

    I'm out of ideas for news-titles

    Successfully tested the Pyra's Wi-Fi at DebConf17. It worked, showed good speeds, but signal strength dropped off sharply with distance from the access point. It seems like, the transmit or receive SNR is worse than it should be.

    Open... and close... and open...

    Wi-Fi was usable (quite fast even) on the prototype at DebConf. But dropped off quite sharply with distance from the access point.

    You could use CO2 spray to chill individual components, and see what makes the vibration quieter. (Ideally set up a high-gain microphone first, with spectral analyser to measure this). I read about some crypto researchers successfully using this technique, to identify potential sources of...

    Power, Memory and Schematics

    I hope FreeBSD may be able to run on the Pyra someday (probably in the distant future). But I'd be happy to run Linux on it for gaming, development and some productivity until that time.

    There may be some relevant information here:;a=commit;h=c879a296889ab8d7adbe7b46184fe2ae86b89cc5 I take this to mean: the charging circuit draws power until the supply voltage drops to some threshold. That could be due to: high-resistance USB...

    Download Pyra Debian OS (WIP)

    Yes, already installed! It should have the latest firefox-esr (45.2.0).
