The Murphy Corner-Line-Array Home Page Project Overview The Murphy Corner-Line-Array (MCLA) is a new type of DIY line array loudspeaker system that I have designed to meet my own requirements for reference monitor loudspeakers with sufficient output to also serve as the sound reinforcement system for my band. I am pleased to make this novel loudspeaker design freely available for everyone who wishes to enjoy this new level of quality in sound reproduction. I hope to provide sufficient detail here for DIY speaker enthusiasts to reproduce the system for their own enjoyment and/or profit. Having been fully described here in the public domain since 9July 2009, my "corner-line-array" invention cannot now be claimed or patented by any third party. As far as I am concerned, everyone is free to use it as they wish with no strings attached. I humbly request only that you openly acknowledge the origin and name of the design.

You could always toss a misbehaving inkjet or laser out the window, but where would that leave you? Truth be told, we need our printers, despite their maddening quirks. Here's a saner idea: Take a deep breath, channel your inner tech support rep, and repair that which has failed you. (Cue sitar.) We've listed the 10 biggest printer annoyances -- of course, your Top 10 list may vary -- and ways to fix them.

Tapered Quarter Wave Tube Back to home pageBack to audio main pageBack to loudspeakers main page First described by Paul Voigt in 1930, TQWTs allow a good quality-to-price ratio. They are also easy to build. Similar to transmission lines, the TQWT is different by its shape, a kind of horn is used as back load but the driver is not placed at the beginning of the cone as usual but on its side. The port is used to adjust the rear flow according to the driver type, internal damping and desired response.

Wireless Power A few years ago MIT created a system for transferring power wirelessly. They transmitted power over a two-meter distance, from the coil on the left to the coil on the right, where it powers a 60W light bulb. Back in 2006, this was a pretty cool thing. You can only imagine what the implications of something like this would be. 5 common printing problems: solved If you are having problems with your printing, we have the solution. Here's how to solve some of the most common difficulties. Printers can run reliably for many years and thousands of prints, but often they do not. Why is this? Sometimes it is as simple as over or under use. Many home users simply don’t use their inkjet printers often enough and this can lead to problems with dried up ink blocking the nozzles.

*** Limes : a Voight Pipe with Fostex FE83 *** "Limes" : A Voight Pipe using FE 83 "Limes" started like a joke, just to spend the time during one of those misty and grey weekend.The need was to have a nice-lookin' and enoughly small cabinet for the living room, to listen to television with your family without renouncing to a good overall quality.Of course low cost was a must. We started the serach of a project last october in our collection of speaker-buildn' rewiews and in the web.After a few day a lot of projects were eligible but.... none passed the ultimate test: our viwes. ;)

DorkbotPDX Instead of a weekly order, 2 layer circuit boards are now sent to the fab when the panel fills up. This means panels are going out 2 to 3 times a week instead of just once a week. Contents Electronics Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive interconnection technologies. Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit. The nonlinear behaviour of active components and their ability to control electron flows makes amplification of weak signals possible and electronics is widely used in information processing, telecommunication, and signal processing. The ability of electronic devices to act as switches makes digital information processing possible.

MathCad Computer Models : Upgraded Versions Last Revised 1/22/13 The MathCad worksheets, that have been available for the past few years, have now been upgraded once again to include several new features aimed at providing a better estimate of a speaker system's in-room performance. A few small changes have been made in the first section of the worksheets to improve the fiber damping correlation, allow the user to defined input power level, and automatically adjust the Thiele/Small parameters to account for the effects of additional series resistance. The second section of the worksheets account for the physical geometry of the speaker enclosure and positioning in the room. Schematics Guide You can see that there are various bits represented by symbols, all connected in various ways. Let’s look at some of the big picture concepts: Left to Right: The first thing to notice is that you read the schematic left-to-right: the input on the left feeds the signal through parts and pathways in the middle to an output on the right. This left-to-right convention is not universal, but it is probably the most common layout for a schematic.
