  • SpinRite v6.1 Release #3
    Guest:
    The 3rd release of SpinRite v6.1 is published and may be obtained by all SpinRite v6.0 owners at the SpinRite v6.1 Pre-Release page. (SpinRite will shortly be officially updated to v6.1 so this page will be renamed.) The primary new feature, and the reason for this release, was the discovery of memory problems in some systems that were affecting SpinRite's operation. So SpinRite now incorporates a built-in test of the system's memory. For the full story, please see this page in the "Pre-Release Announcements & Feedback" forum.

  • BootAble – FreeDOS boot testing freeware

    To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.

    GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.

    The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.

    You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.

    (You may permanently close this reminder with the 'X' in the upper right.)

I seem to recall that Steve was trying to measure REM and deep sleep some years ago.
I wonder if this project might help, it's a HAT i.e. daughterboard that goes on top of the Raspberry pi 3/4.
In the video the inventor has a "hat" or helmet that he constructed.
 
My Samsung Galaxy Watch Active 2 with the Samsung Health app breaks down my sleep into awake / REM / light / deep sleep.
Yes my Fitbit does as well however Steve's assertion has been that if you don't measure the brain waves directly, then it's not truly accurate.
Seems logical, as sleep happens most centrally in the cranium.

I agree that would be more accurate. The problem with that is the same problem my wife had when they did sleep study. Being wired up changes your normal sleep pattern.
 
I didn't see power supply isolation on the schematic or ADS1299 datasheet.
Don't know if I would trust my life to a chinesium wall wart powering a PI with a low Z connection to my body.

Those sleep studies avalible to common folk are a psuedo-science MD money machine. I haven't heard on one person who gained anything from them.
