7 Inside a 5mw laser pointer.wmv

Read Hear: Some discoveries of a common 5mw “dollar store” laser pointer. In the video you can see an onboard surface-mount resistor. I measured this with a meter to be 68 ohms. Then I looked at it with a magnifier and on it is 68RO so I guess I was right about that. This seems to be a current limiting resistor, and maby if this is lowered, the laser could work at a lower voltage, maby 3V. Without any power applied to the laser, I looked into the lens, and I could see light comming through from a nearby lamp I have here, so there is basically nothing in there except a very small laster diode that sits on a thin “shelf” of sorts that goes horizontally across, about 1/8 inch or so behind the lens. I finally took the front lens out, its held in position, not by glue, but by a 1/4 inch long spring behind it. This spring has about the same diameter as the lens. The lens seems like some hard plastic, an probably protects the laser diode and modifies the laser lightbeam (makes it thin/narrow?). The actuall laser diode is very small, about 1/32 inch square.

RS Series Resistance Substitution Box

The IET Labs RS Series Resistance Substitution Boxes, is made up of seven cost effective models, starting at less than two hundred dollars. These decade boxes are indispensable tools for engineering, design, troubleshooting, or service. They are perfect for the lab and small enough and rugged enough for use in harsh field environments. (During this paragraph show all eight models or as many as you think are practical: RS-200, RS-201, RS-200W, RS-201W, RS-200-2W, RS-201W-2W RS-RTD, RCS-500). The RS Series Resistance Substitution Boxes employ color coded, deep gold plated, low contact resistance, thumbwheel switches. Any resistance is simply set and read as one number. For example to set 32467 ohms. (Dial starting with setting on all 0’s dial 3-2-4-6-7 on an RS-201, dialing the 4 switches on the right) That’s all it takes. This system is leaps ahead of similarly priced decade boxes that use confusing, error prone slide switches. The seven standard models cover a wide range of resistance values from as low as ten Milli-Ohms up to one hundred Meg-Ohms. They have accuracies of point one percent to one percent and power ratings from a half watt to over two watts . We also have the RCS models that combine resistance and capacitance. (Show Bullets here) Additionally, the RS Series can be customized to meet your specific needs. The RS Series substituters are manufactured in the United States and are the most practical and economical resistance substituters you can own, packing a

GM Starting Electrical problems on 99 01 02 03 04 05 Impala Grand Am Malibu by ENORMIS of Erie, Pa

This is our tech tip rant… GM HAS a problem with these cars, WE are tired of being blamed for it.  WE KNOW HOW to solve it. SIMPLE RESISTORS and RELAYS DOES NOT FIX PASSLOCK II vehicles.***Please do NOT waste your time submitting a response trying to tell us how to permanently fix the problem. We will NOT post, respond, or even read your comment.*** We know how to fix the problem and this is how we make our living. (Because of all the MORONS out there THINKING they know how to fix this problem we have turned COMMENTS OFF….) We are seeing many 99-08 Gm Electrical issues. We are solving and diagnosing these issues. Certain mechanics are blaming aftermarket remote starts etc. if they happen to be in the vehicle. WAKE UP !! GM HAS A PROBLEM. THESE PROBLEMS are HAPPENING WHETHER AFTERMARKET Electronics are installed in the vehicle OR NOT! We know to diagnose and we will fix these cars. GO to safercar.gov and report YOUR GM Problems !! THE FOLLOWING BELOW CAN BE FOUND AT: www.consumeraffairs.com Melinda of Orlando FL (09/07/08) I purchased a 2003 chevy impala alittle over a year and my car is [bad]. First it started of with the sercurty light coming on which made my car not crank and now its more and more problems these cars are no good and I still have to pay the car note. Samantha of Belding MI (08/06/08) I own a 2003 Chevy Impala. I purchased this car in Sept. of 2005. 3 days after we purchased the car, the Security light came on. 5 days later, my car wouldn’t start

Assembly at Home Jobs – Electronics Assembly at Home Jobs

Assembly at home jobs involved the assembly of many products. The beauty of this kind of work is that you will be taught the assembling techniques of a broad range of products. If you would wish to assemble electronic products, the company will provide you with a step by step instruction which would be very easy to understand because of the simple English and the illustrations that go with the step by step process of assembly instructions.

In fact, even if you have no knowledge about electronics and it would be your first time to touch and hear about the names of those tiny electronic components such as transistors, resistors, capacitors, and other electronic items, you can still go about the assembly of these products. Of course, it is a must that you know how to read and understand English correctly in order for you to be able to assemble these products based on the instructions. Actually, assembly at home jobs that would deal about the assembly of electronic parts can be of several types.

You can be given assignment to assemble electronic components that would only need tools such as long nose pliers, screw drivers and cutters. This kind of assembly will make you assemble electronic parts through the use of these tools. Another kind of electronic assembly will have to make you use an electric soldering gun and even a simple tester to test the product. With this kind of electronic assembly at home jobs, the company will have to provide the assembler with an electric soldering gun, lead for soldering and a simple electric meter for testing.

These tools will come attached with how to use guide. Anybody can easily learn to use these tools. Assembly at home jobs dealing in assembly that need specialized tools will need to have separate instructions in how to use such tools. These instructions, aside from making the user learn how to use the tools, will also provide for the necessary safety tips to preclude the worker from getting hurt through the wrong use of such equipment. It has been noted, however, that most of assembly at home jobs worker choosing electronic product assembly jobs, have some basic knowledge of electronics, the reason why they go for this kind of assembly work.

Electronic assembly at home jobs are offered by many businesses and companies involved in the manufacture of electronic products. Because of the growing market of their products that are used in many electronic applications such as FM radios, Cassette Disc players, digital cameras and even cell phones, the need for electronic assembly at home jobs workers are badly needed by these companies. This is also one reason why even those without basic knowledge in electronics are being taken in by companies so long as the applicant home worker knows how to read and follow instructions. In effect, if you think you are ready to follow instructions in the assembly work of electronics product, this kind of assembly at home job which is an easy and profitable way of using your idle time at home is truly suited for you.
