Do you need an external set of eyes to participate in design reviews for electronics / embedded / RF systems? A good review process can uncover issues before the next phase when dealing with them is much more expensive.

We’ve been counting down 🚀 On March 30 at 6:20 a.m., a satellite carrying a payload designed by Valpo students will launch aboard a SpaceX mission. From classroom to cosmos — this is hands-on learning in action.

@ValpoCoE has joined NearSpace Education's Dream Big Program to design a satellite communication system. With an ambitious April deadline, the satellite will launch in late 2025 or early 2026 🚀 Learn more about this interdepartmental opportunity at bit.ly/valpodreamsbig!

Can the way kids play with toys influence whether they become engineers? @PurdueENE Professor Ruth Wertz’ @NSF Early Career Award is funding research on whether building toys like @legos enhance spatial skills and shape early engineering identities. tinyurl.com/2bnde7pj.

Evidence that students in Electromagnetics have been making connections in the content, c.f. the Slack channel:
astronauts with gun meme: Wait, so all to do to get the magnitude of the electric field is to surround your source of charge by a suitable Gaussian surface and the math will do the rest? Always has been, friend.

This has been a kiloton of fun this far. Students have gone from no programming to making their own robot control scripts and customizing the robotics hardware.

The COE is hosting their inaugural Valpo Accelerates Engineering Summer Camp for High School students interested in engineering. Each morning the students have modules covering a range of disciplines, & in the afternoon they work on week long projects in robotics & bioengineering

The trick is to do this just after the add/drop period. Giving their own code from last year is sufficient.

One thing I would LOVE LOVE LOVE to see universities doing is a sort of coding Kobayashi Maru module on their 3rd year tech students. Give them a shitty, cobbled together codebase, roleplay an over-demanding client, and an unrealistic deadline.

In 1939, William E. Urschel created a technology very similar to the one used for today's 3D printed building. He did it behind a small warehouse in Valparaiso, Indiana and called it "Wall Building" machine [full video: buff.ly/3tHAJiz]
