A prototype watch, raising hope for Parkinson’s
&gt; As part of her work, Zhang researched the root cause of tremors. She spent six months, off and on, building prototypes. She sometimes worked in her London home, soldering wires to PC boards and tinkering with coin cell motors to create vibrations. She tested early versions with four other people with Parkinson’s, producing promising results for three, spurring the idea forward, she says.<p>This paragraph reads like the solution is not as simple as strapping a vibrator to a wristband. So where are those results documented? Does anyone have an idea where the source code and schematics are for the singular Emma device prototype?<p>Edit: I have not been able to find source code yet. A reddit thread about the device [1] from December 2016 links to a screenshot [2] of a BBC documentary from which one can infer that Zhang used six motors for the Emma device and timed them in a specific way.<p>Edit 2: I noticed that my other HN comment [3] asking if this article is a PR submarine was first upvoted until it was shown at the top of the thread. It was then downvoted until it moved to the bottom of the thread. If a HN mod is reading this: Does that voting pattern seem normal?<p>Edit 3: Now this comment is also receiving downvotes?<p>Edit 4: The BBC has a GitHub repository containing other code related to the documentary. There has been an issue opened in January 2017 [4] from a person who wants to help his father who has Parkinson&#x27;s. No source code seems to have been released since then.<p>[1] <a href="https:&#x2F;&#x2F;www.reddit.com&#x2F;r&#x2F;Parkinsons&#x2F;comments&#x2F;5hh2fx&#x2F;emmas_watch_a_few_engineering_thoughts&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.reddit.com&#x2F;r&#x2F;Parkinsons&#x2F;comments&#x2F;5hh2fx&#x2F;emmas_wa...</a><p>[2] <a href="http:&#x2F;&#x2F;i.imgur.com&#x2F;0q0QHsj.png" rel="nofollow">http:&#x2F;&#x2F;i.imgur.com&#x2F;0q0QHsj.png</a><p>[3] <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=14388178" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=14388178</a><p>[4] <a href="https:&#x2F;&#x2F;github.com&#x2F;bbc&#x2F;MiD&#x2F;issues&#x2F;3" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;bbc&#x2F;MiD&#x2F;issues&#x2F;3</a>
