What is the mcd intensity of LED on the front of my Dell tower?
What is the intensity of the mcd LED on the front panel my Dell tower? I'm wanting to buy LEDs for a project, but I have no idea of how bright LED to buy. I want to buy an LED 7000 mcd rating, which means nothing to me. I need to know the brightness of the LED on my Dell just had a kind of comparison.
Chuck right – I would say about 15mcd. MDC = milli-candelas. 7000mcd would be considered high intensity. However, for pennies, you can get 20 000 mcd and is more complicated than that. You see them used in advertising displays in stores. They are very catchy and take little or no more power than its Dell (20 m / milliamps (). The previous comment on the angle of post office, are also more effective is fundamentally sound. If this is all new to you, you have to put a resistor in series with the LED. I use a rule base 560 ohms for 5V and 12V 1k. This is almost certainly wrong, but it works (And certainly well below th power of a good size). correct calculations abound on the web. Email me if you want more detail specifications and methods of sufficient strength to the wiring (for example, there are risks with LEDs in parallel, in certain configurations – not all).
"I can build a digital VGA controller so you can use my laptop LCD as a monitor for my desktop PC?
I PC LCD laptop I use as a monitor for my desktop computer. I need to convert, however, analog VGA signal to digital PC to run LCD screen. I read somewhere that I can do with an FPGA using VHDL. I just want to know what program because If I do not understand very well how to convert successfully.
VGA is analog. Therefore, you need to build an analog digital. You will need to quantify the analog voltage to obtain a digital representation. Once I had, you want to build the digital signal. I have not compared the VGA and DVI specifications, but you may need to use multirate sampling technique to match the analog and digital resolution, see the first link in the sources, Chapter 4. big question for you, however. This project is not trivial. If you do just for fun, why not buy a ready-made business solutions. See second link sources.
Is there a way around 1980 kitchen cabinet depends on copper appear more money than bronze?
I am refinishing my cabinets kitchen and would like to keep the hinges if possible, but I want to match the silver buttons and pull back will be installing. Then I wondered what you can scratch the coating brass or applying a chemical to move and view its coppery glow of having more money … same if not brilliant. They are like hinges, after all.
The only practical option is to have them chromed. There are usually places in the yellow pages that make that sort of thing.
A solid brass basket act as a Faraday cage good?
From the top is also covered by a sort of brass? I wonder how good a Faraday cage only if one of these pulses EMP decides to saturate my neighborhood because of a nuclear war. So as an additive would be a simple bottle, biscuit tin (the kind with the clowns and unicorns on it) work?
Only if I had a top line.
