Deepsea Challenge - 10 years later

Posted by Ben Orchard on Mar 25, 2022 7:00:00 AM

This month marks the 10-year anniversary of James Cameron's historic dive to the Mariana Trench with the help of Opto 22 controls.

About this time 10 years ago, I got two emails about an hour apart. The first was from my wife saying my 16-year old son had fallen off his skateboard and taken a chunk out of his elbow. The second was from my son himself, asking if he could go back and find the missing bit rather than go to hospital to get stitches.

Today, we all have a bit of a laugh about it when we recall the story. But at the time, it was pretty stressful for each of us, mostly because I was away from home half way around the world.

In fact, I was a thousand miles out at sea working with the team that was preparing the Deepsea Challenge submersible that would end up taking movie director and deep ocean explorer James Cameron to the deepest point on the planet - the Mariana Trench.

New REST API Node-RED Video

Posted by Terry Orchard on Jan 26, 2022 7:11:10 AM

New video just added to the Node-RED developer playlist covers a simple API flow using daily weather data as an example.

Node-RED is an extremely powerful tool that we’ve featured many times on this blog and our YouTube channel, and one very common use of Node-RED is to use application programming interfaces or “APIs” to move data between devices and/or services that would otherwise be totally disconnected.

To help you get started using APIs with Node-RED if you’re unfamiliar with these tools, we’ve just made a new video about how to build a simple API flow using an example web service for daily weather data.
