Starting with this new AddOhms TutorialCast series, we are taking a look at Electronics Basics. The first topic is on the differences between Voltage, Current, and Power. The twist on this explanation is that we are not using the usual “electricity is like water” analogy engineers seem to love. Instead, we just use plain language to explain the difference between these concepts.
The concept of “cut copy and paste” goes back to a time when people hand wrote all of their documents. The modern concept was introduced to the computing world by Xerox PARC and Apple’s Lisa / Macintosh Now nearly every piece of software offers some level of copying and pasting, including CadSoft’s EAGLE Schematic and PCB software.
Editing video has been something I enjoyed doing since High School. There I used my first tape-based NLE video system to make a Jeopardy episode where I played both a contestant and the host. In the skit I got into an argument with myself. Of course that was long before tools like Final Cut, After Effects, or even digital video cameras existed. Now anyone can do cheap effects for fun.
Speaking of cheap effects, using a little bit of Final Cut Pro X magic and a piece of green paper, I was able to achieve this effect:
Why am I working on this? Stay tuned… (you can probably guess where that’s going.)
Recently I realized most of my projects were all Arduino-based. There are lots of other prototyping platforms available in the market, and the TI LaunchPad, based on the MSP430 is one of them. In fact, I have had one of these boards sitting in my box of stuff ever since they came out. At $5, they because an impulse purchase when I was buying some other stuff.
So, I dusted off the original box and recorded opening it up. Let’s see how it works.
A couple of weeks ago I posted an EAGLE Tutorial on creating Ground Planes. That tutorial has now been updated with the above YouTube video showing the steps. Let me know if there’s anything else I can do to make it more clear.
