shiny things and dusty things

I made myself into an LED mummy for science. Sort of.

Let's take a look one of our principal suppliers of soldering tools -- Weller!

  • When he gets there, I hope he'll find some time to teach his dad!

  • Amazing--thanks for sharing! It looks like MIT neuroscientists this year (drawing off that 2016 study) found that if they combine the visual with auditory stimulation, it's even more effective than either one by itself. Fingers crossed that they're onto something that will work on humans.

  • I'll have to check this out next year. Looks like fun! Your photos came out great.

  • It's called a "Thing Plus" because it uses the same footprint as the ESP32 Thing Plus.

  • We've fixed the description and hookup guide link--thank you for catching that.

  • Should be 6 SERCOMs. We've fixed the Features tab accordingly--thank you for pointing this out!

  • Sure, but Yahoo comes with confused expressions (free of charge) whenever I give that email to people as my contact info.

  • Thanks for your feedback--glad to know we're in you're top four! I really like the throw-away email idea. My old yahoo account has (inadvertently) become just that!

  • Thanks Pete--this brought back repressed memories of helping the techs with testing back in the day! You try to find that sweet spot, just the right amount of pressure in just the right direction, but the moment your hand jiggles or twitches, bam, time to start over. It was a trip to read about all the evolution that's happened since then.

  • Thanks for your comment. There's some more info on it here, although it still leaves us hanging a bit as to their ultimate conclusions and what changes were made to their soldering methods as a result:

    In Space Soldering Investigation

    Soldering Surprise

    There's also this explanation of what we're seeing in that video:

    "Real-time downlink video of the experiment yielded direct observation of the solder melting, equilibrium shape attainment by the liquid, and flux movement. The flux movement was particularly noteworthy because it was entirely unexpected. When the flux was released from the solder during heating, it formed a droplet that spun around the larger solder drop. This surprising movement is driven by thermocapillary flow induced by the temperature gradient. This type of behavior cannot be duplicated on Earth."

No public wish lists :(
