In order to be the best engineer that you can be, you need to be the best person that you can be. Along those lines, I have created a new site: http://faith.granzeier.com/. There will be articles and other things to help you to build your faith there. In fact, there are already a couple of articles posted there. Take a look there (just click on the link on the right side of this page,) but, as Bill Cosby used to say: “be careful, or you just might learn something.” 😉
Also, Granzeier Consulting is about trying to help engineering students learn about computers and control systems; our tagline reads: Helping to Build a Better Engineer. In light of this, I have started updating our store and adding some tutorial pages to this Projects site.
My first update was to the LED Pack product page: https://www.tindie.com/products/Granzeier/led-prototyping-pack/. The old description was just the first paragraph. I have added an entire tutorial on LEDs for beginners. Soon, I will be adding some specific examples so that you can see exactly how to use an LED in your own circuit.
There is also an entire tutorial page, showing how to set up and use a solderless breadboard. You can find it here: http://projects.granzeier.com/what-is-a-breadboard/. You can learn about the history and how the things work there. I even show you how to put a power indicator on your breadboard, so that you can, easily, tell when power is turned on.
