Interesting time code jump points:

EAGLE 9 Hands-On | Live #6.

Sun, 22 Apr 2018 08:51:00 +0000

We take a look at EAGLE 9.0. This release was a major update since Autodesk took over the project. To help, I used a class I wrote for TechShop as a guide.

In the end, I was happy to see the progress Autodesk has made. However, I’ll be sticking to KiCad.

Evil Mad Scientist Laboratories sells two of the coolest soldering kits around. They are huge discrete versions of the popular 555 timer chip and LM741 Op-Amp (operational amplifier.)

These kits are just amazing. Detailed, fun to build, and look great on your bench or desk. Over on baldengineer.com I made a full review of the XL741. Same comments could apply to the Three-Fives as well.

While not the same as the full tutorial, think of this as a step-by-step how-to build a kit tutorial.
