SMD Project Kit 2: Surface Mount Soldering Practice Kit
Saturday, March 12th 2016
Been working on some more surface mount soldering practice. One of the reasons I'm focused on this right now is because my cousin has a project for me to work on that involves SMD work. I want to make sure my skills are up to par before going any further.
The completed kit above I got from eBay. It was less than dollar with shipping. Granted it took several weeks to arrive from China. But it was well worth it. I threw the quarter in there for scale. The kit has several sizes of resistors with different values. On the smaller units, I had to utilize a magnifying glass to do most of the work. I also was careful to use flux this time. I think that made a huge difference. Especially when it came to drag-soldering the IC. Speaking of. The IC is a LM339 comparator chip. But honestly I can't tell you exactly how it's used in this circuit.
Matter of fact, there isn't a whole lot of documentation with this kit. It's possible that the kit is mainly testing for polarity. If you get a lit LED after hooking 7-15 volts DC to it you're good. Kinda like a pass/fail test. Either you get a gold star or not. However it is a really good practice kit for the money. I've got some more kits lined up from Flyandance. Hopefully I will get around to doing those kits as well. I'll be sure to put them up too. See ya next time!

I saw this earlier today and thought I would share it. My wife and I have been studying karate since last May (2015). Sometimes it's hard to see the big picture. We're making great progress. But this quote really put things into prospective. In learning we make mistakes. It's part of learning. We will make a ton of mistakes in our existence. How else can we master something without learning from our mistakes? Food for thought! Not just in karate, but in life as well.
