<p>Finally got my Veho microscope in the mail today (had to cancel the Digimicro order). Followed Kevin's instructions and it just worked auto-magically. Thanks Kevin! So we are good to go for a microscope demo @Scale9x. No dice on the Intel play microscope but not giving up yet. </p>
<p>Cheers,<br>
