PineTab-V launch (RTheren)


  • The PineTab2 we talked about last week with an ARM RK3566 64-bit SoC will be available for pre-order tomorrow, April 13th.
  • And so will the PineTab-V which is based on the JH7110 64-bit RISC-V SoC.
  • The PineTab-V is the Star64 single board computer released earlier this month.
  • And is extremely experimental, with limited Linux support, and is to be viewed as a development platform.
  • The PineTab-V is deep matte black while PineTab2 is silver-gray.
  • And the PineTab2 the DanctNix Arch Linux for Arm software can be best described as early but very serviceable, and there is little doubt that before long improvements will be made and additional functionality enabled.
  • The PineTab-V doesn’t come with an OS installed.
  • So it looks like the Pinetab-v we talked about last week is not an April fool’s joke! LOL
    • Different SOC. 
    • That one was powered by “Powered by unicorns and candyfloss “
  • It means Pinetab Risc V!


Last call for maintainers (Byatcko) 



  • Six months ago the developer of GWR was looking for a new maintainer. 
  • Nobody has stepped up. 
  • It no longer functions with Flatpak (still works without it)
  • If nobody steps up in the upcoming weeks it will be declared abandoned. 
  • Roberto seems willing to hand it over to just about anyone and Armit has stepped up. 
  • I want to get some additional attention on this. 
  • Some nice features. 
    • GPU and Memory overclock offset profiles
    • Custom Fan curve profiles
    • Change power limit
    • Historical data graphs
  • Additional contributors would be nice in case Armit chooses the dark side and joins team RED. 
  • I use it for my 3060 to keep the fans from going brerp.  
  • OMG!  GreenWithEnvy is a marvelous app and I have it installed on multiple machines and use it regularly.
  • I use it to monitor GPU temps and for overclocking playing certain games, like DOOM 2016.


OBS Compile guide 


  • Why in the world would you want to build OBS?
  • That’s simple, really. 
  • You might want to run the latest and greatest, help test proposed updates & features, or have the simple satisfaction that comes with building it yourself. 
  • If you’re running Debian I’m going to show you the Venn way of doing it. 
  • The reason I build OBS is to strip out the parts I don’t use. 
  • Things like Pulse, Alsa, VST, VLC, V4L. 
  • You might want to take the opposite approach and build everything.
  • Hey, now you can.  

Slice of Pi

MAC Pie 


  • This is kind of an odd use case. 
  • If you have  a Mac Plus/SE/Classic and want to use it well, there is hope. 
  • Is the CRT on your Mac Plus, Mac SE or Mac Classic not working, taking a long time to fire up or starting to give up the ghost?
  • Well then, we have a fantastic fix for you!
  • The developer, guruthree on GitHub has created a converter to convert the video output of a Mac Plus/SE/Classic using a Raspberry Pi Pico to either a VESA compatible VGA signal or a Monochrome composite video output.
  • This is an active adapter that digitally reads the Mac’s 512×342@60.15 and converts it.
  • The VGA signal is to 1024×768@70.2 which should work with any VESA compatible VGA monitor. Composite video output is PAL 288p@50/576i@50 format.
  • guruthree use case for this is using an old Mac SE motherboard he had saved from back in the day.
  • Hardware Requirements:
    • A Raspberry Pi Pico
    • A logic level converter
    • A breadboard might be useful
    • For VGA output, a Pico VGA demo board or equivalent is needed:
      • Pimoroni Pico VGA Demo Base
      • pi3g
      • Build your own from schematics
    • For composite video output, a resistor digital-to-analog converter, or DAC, is needed.
  • Software Requirements:  Pico C SDK and Pico Extras.
  • I have a Mac SE and a Mac Classic, but on both of them the CRTs still work, but my Mac SE is starting to take a long time firing up.
  • This is a lot easier than wiring a new CRT, and a lot less dangerous.
  • Trying to find a replacement CRT has to be a pain. 
  • This is using a Raspberry Pi Pico and a Pico VGA demo board.
