In mechatronics and control theory, testing is an important part of controller validation. You need to run experiments to prove that your software/analog/digital controller, actuator, algorithm, etc, does what it’s supposed to do. Experiments, however, can be expensive, time-consuming, difficult,
dangerous, or even impossible to test under all conditions. Therefore, you can do Hardware in the Loop (HIL) testing and Software in the Loop (SIL) testing/simulation to aid the testing, verification and validation of your controller without having to resort to pure, fully-physical testing with actual products under actual conditions.

My review on my latest desoldering tool purchase (< $10)!

I just bought this Velleman desoldering iron/vacuum (desoldering pump) for ~$10 on Amazon. It worked so well I wanted to share my review directly, since it could have saved me dozens of hours and tons of frustration before when I was newer to soldering and trying to desolder through-hole parts with lots of legs, such as switches. It is SUCH a great value and would have prevented me from destroying or damaging several circuit boards in the past!

I just upgrade my hard drive to an SSD (Solid State Drive). Now my computer runs soooo much faster! It's usable again! No matter what operating system you have, the following instructions will work, since we will simply be using free and open source, and also no-cost, tools to copy your drive data, byte by byte, from one drive to another. In other words, the copy technique doesn't even read files, as it doesn't know what files are, so it doesn't care what file structure or format you have. It just reads bytes. I'm pretty excited that such great free tools exist. No need to buy Acronis, just do this.

How to clone your hard drive:

1. Buy an external hard drive USB enclosure. Ex: Sabrent Ultra Slim USB 3.0 to 2.5-Inch SATA External Aluminum Hard Drive Enclosure [Black] (EC-UK30) ($8.99).

2. Buy a nice new SSD. Ex: Samsung 860 EVO 1TB 2.5 Inch SATA III Internal SSD. Place the 860 EVO into the enclosure and plug it in.

3. Make a bootable USB flash drive containing Linux Ubuntu 16.04, or whatever the latest LTS (Long-Term Support) version is at the time.

tldr;

Buy one of these USB to Gigabit Ethernet adapters for $10, plug it in to your Raspberry Pi 3 and voilá! Your new Pi 3 Ethernet connection is now 3x faster than the built-in Ethernet port and 12x faster than the built-in WiFi adapter (source: see my test results below)!

This really matters when you're using your Pi 3 as a network device, server, router, hotspot, NAS, or remote development machine. Pretty much it really matters whenever you want it to work better on your local or wide area network, which includes ssh-ing or otherwise remoting into it.
