Received O-Scope in the mail!!

Ok so I received the scope in the mail on tuesday and was very happy to discover that everything was working as designed!! The calibraion sticker does show that it is still in callibration. I will post some more pictures shortly.

The Beast!

Since I'm on the topic of oscilloscopes I thought I would post a picture of my Tek 545B O-Scope. This thing is a beast! It weighs at least 70 pounds and has over 100 vacuum tubes. When powered up it draws about 500 watts!! the current plugin module states it has a 30 Mhz bandwidth which isn't bad for its time.

Good Buy... I Hope...

So I decided against buying the multimeter at this particular moment in time. I instead purchased a Tektronix 2246 oscilloscope. I couldn't resist the price, and it's still in calibration according to the documentation. The only thing that scares me is this particular model has a known power supply issue; hopefully its just a simple capacitor swap. Anyways, I have not received it yet, but when I do I'll write a short review.

Junk Multimeters!!

So I went and bought a $100 multimeter a few days ago hoping I would be getting a decent meter... Well I was wrong. Very wrong... After the first few measurements it decided to randomly turn off. conveniently, I was on a roof at night testing the running capacitor on a commercial air-conditioning unit. After fiddling with the selector switch I soon discovered it to be malfunctioning. needless to say, I promptly returned it for a refund. After much frustration with the notorious lack of quality control on imported meters, I decided to look for a meter made in the U.S.A. After some searching I found the one!! Its a Fluke 289. For $580 I'm sure it will function properly!! I will be ordering this beast in a few days, and I will definitely follow up.

Welcome!!

Hello, and welcome to my blog! My name is Eric McGaha and, as most of you already know, I am currently attending Frederick Community College. I'm currently working towards an associate degree in general engineering. After I graduate I plan to attend the University of Maryland and pursue a degree in electrical engineering. My eventual goal is to start a business after I graduate. As most of you have probably already figured out, I'm a severe electronics enthusiast (aka. NERD!). I have been interested in electricity since I was able to walk... Well maybe not that early, but it wasn't long after! Enough about myself, now I want to tell you a little about the future contents of my blog. I will be sharing my knowledge and love of electronics. I will include many interesting science/tech related topics. They will include everyting from Tesla Coils to CNC Machines, and whatever else! I'm creating this blog for my class assignment; if you see posts which are irrelevant to electronics or electricity, this is why. Even though this blog is being created for a mandatory class assignment, I'm still going to take full advantage of this opportunity. I hope you find the information posted enjoyable and helpful; I will do my best to continue to keep it fresh and interesting. Thanks again for visiting!
