Last week was spent more with hydraulics with an intro into preventive maintenance. The Bobcat mini excavator became a great teaching tool in that we were able to actually see and feel the hydraulics working and not just look at a schematic. My group and I traced through the joystick pilot controls and not only learned the system but studied about what the specific service schedules and procedures were. I feel confident in the hydraulic system in that particular machine as well as what the needed servicing. 

On a somewhat related note I was driving over the pass and had some transmission problems. Looks like I'm going to need to pull it and dive inside... More pictures to come.

This week was spent on hydraulics and we dove into the bobcat joystick and pilot control system. We looked through schematics and traced the entire system so we could see exactly how this system operated. I put to use the knowledge of schematic symbols as there were a few within this system. Not only did I learn a ton about a pilot control system but I was also able to operate the machine multiple times and refresh my memory with that.

Last week the highlight was going down south to BG Machinery. We were able to see a business that thrives of of everything we are learning in class. This shop takes on heavy duty machinery engines and re-furnishes them. The biggest thing I took from the tour was how their attention to detail and precision. These guys work with measurements that are 1/30th of the size of a human hair! Their product comes back more precise than when they leave the factory! It was quite the experience and despite the fact it's in Seattle it would be an awesome place to find a job at.

Last week was spent studying about hydraulics and basic operations of different systems. Hydraulics are much like electricity. I spent some time on the board going through the assignments and quickly found things I didn't understand. I had to learn a few basic hydraulic symbols and their operation. One thing I learned is different valves that are restricted depending on different pressures or temperatures. Pretty cool stuff! After I figure out how to post videos I will add to this blog

This week I continued wrapping my mind around the electrical. I focused a bit on transistors and their function. I find the transistor to be the most interesting piece of an electrical circuit that I have come across so far. Basic function that the base current can control and amplify the current between the other terminals. Wouldn't mind getting my hands on one this week and playing around with it a bit more.

I also spent time this week In the shop fabricating a hand rail and fixing downspouts we had previously built! Man!! Though it was not our mistake,patients is tried when you have to build things twice. I've Learned a lot this week about your mindset going into a job or project. It can either make or break your entire project if you come into it pissed off and mad or the opposite.

Last week I spent some time refreshing my memory with the test boards. Seems to have stuck with me. Although testing on the board always seems less complicated than on a truck! Another thing I worked on in class was taking apart an alternator and messing around with the slip rings and rotor. We calculated current using the ohms and our source voltage and hooked it up to create a magnet. I was brought back to what I had learned in ADTech learning about power generation and alternating current. Below are some pictures.

We started class again today Im excited to refresh my memory with some electrical. I spent a little time this evening going through some old schematics we had to color code and creating the new one for tommorow. I also was searching around the internet for some electrical videos and came across one that is pretty mind blowing. There is a bit of information out there on it but it seems to be fairly new technology that could literally change the way this world stores energy.

WOW!! The possibilities for this are endless....

This could make for some interesting topics in class?
