A Blockchain, Robotics And AI Event In Vietnam

Blockchain Education Network Vietnam recently held an event titled “Building a Robotics & Artificial Intelligence Ecosystem with Blockchain”. The title alone has three of my favorite things in it, so when a client of mine asked me if I could put together a little hardware demonstration for the event, I jumped at the opportunity.

I also thought I’d take a moment to write about it, because I haven’t seen much coverage of emerging technology events in the developing world, and the fact is that there’s a consistently high level of interest. I’ve yet to go to an event that wasn’t filled to capacity, and I hope to share some of that enthusiasm with you.

ETextile Spring Break Tackles Signal Blocking, Audio Generation, And Radio Transmissions

Finding a killer application for e-textiles is the realm of the hacker and within that realm, anything goes. Whether it’s protecting your digital privacy with signal shielding, generating audio with a wearable BeagleBone or 555 timer, or making your favorite garment into an antenna, the eTextile Spring Break is testing out ways to combine electronics and fabric.

You may be asking yourself “What are e-textiles good for?”. Well, that’s an excellent question and likely the most common one facing the industry today. I’m afraid I won’t be able to give a definitive answer. As an e-textile practitioner, I too am constantly posing this question to myself. There’s an inherently personal nature to fabric worn on the body and to our electronic devices that makes this answer elusive. Instead of trying to fabricate some narrow definition, what I offer is a look at topics of interest, material experimentation, and technical exploration through the lens of a week-long event held recently in New York called eTextile Spring Break.

We Need To Have A Chat About Something Important

Yes, I really did print this the day before the story broke.
Yes, I really did print this the day before the story broke.

With hindsight, I picked the wrong day to 3D print a Cap’n Crunch whistle downloaded from Thingiverse. I was covering the hackspace textile evening, so I set the Ultimaker going and headed off to spend my evening making a laptop pouch. My whistle, a reasonable reproduction of the famous cereal packet novelty whose 2600 Hz tone allowed special access to American telephone networks, was ready for me to take away as I headed home.

The next day, there it was. The legendary phreaker [John Draper], also known as [Captain Crunch] after his use of that free whistle, was exposed as having a history of inappropriate conduct towards teenage boys and young men who he encountered in his tours of the hacker community as a celebrity speaker.

My whistle will no longer go on a lanyard as a piece of cool ephemera, it’s sitting forlornly on my bench. The constant procession of harassment allegations that have been in the news of late have arrived at our doorstep. Continue reading “We Need To Have A Chat About Something Important”
