This week the bald engineer unboxes swag from electromaker.io, programs the Adafruit Coin Accepter, with a Pyramiduino, and answers questions along the way. Interesting time code jump points: 7:59 - See Programming Bootloader Clip 12:11 - Coin Acceptor Programming 18:00 - Pulses on the R&S RTM3004 Oscilloscope 42:05 - Code working as intended!

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.

https://youtu.be/uha7NoUskEg 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.
