DIY FAQ - DIY_Wiki From DIY_Wiki DIY Stompbox FAQ. Copyright 2006 by Aron Nelson, All Rights Reserved. Here is info to help you get around problems I had when I was starting out... SKILLS you need to build your own stompboxes. For the new guys.... Try a beginner project. How to mod your pedal. Already built a pedal, but it has problems? Wondering what part does what? QUESTIONS??? What is that upside-down triangle - is that ground? Yes, it is ground. Where do the connections that show a ground symbol go to? Generally speaking, take all the ground points, connect them together, then connect them to the ground lug of the input or output jack. Pots - How do I wire pots? Apparently there's a standard for the terminals. When viewed from the front, a pot turned fully clockwise connects terminal 2 to terminal 3. Pots - When do I use audio or linear taper pots? You can use either one at any time. Pots - What is the difference between linear and log or audio taper and how do pots work? Check out the Secret Life of Pots at GEO.
HNTE - RGB LED Cube OK so I have finally found some time to begin writing the story of my RGB LED cube, this project was always going to be the next step in the evolution of my LED Cube. I can only hope that it will be as popular as my original cube, for those of you that followed my original cube project you will probably notice a few similarities. I built the RGB cube while I was living in the UK for 6 months, so I had access to a limited number of tools and most of the work was done on the dining room table to the dismay of my girlfriend (wife now). Working on this project I have learned a lot about animating in colour, software modulation for fading and c++ in general, so hopefully I can teach you readers a thing or two as well. If nothing else at least you will be able to use what I offer here to build one of the greatest light displays you have ever seen! (If I do say so myself :P).. Before I Begin Getting Started So first things first, how much time should you set aside? Price List The Cube Assembly
24/192 Music Downloads are Very Silly Indeed Also see Xiph.Org's new video, Digital Show & Tell, for detailed demonstrations of digital sampling in action on real equipment! Articles last month revealed that musician Neil Young and Apple's Steve Jobs discussed offering digital music downloads of 'uncompromised studio quality'. Much of the press and user commentary was particularly enthusiastic about the prospect of uncompressed 24 bit 192kHz downloads. 24/192 featured prominently in my own conversations with Mr. Young's group several months ago. Unfortunately, there is no point to distributing music in 24-bit/192kHz format. Its playback fidelity is slightly inferior to 16/44.1 or 16/48, and it takes up 6 times the space. There are a few real problems with the audio quality and 'experience' of digitally distributed music today. 24/192 solves none of them. First, the bad news I was also interested in what motivated high-rate digital audio advocacy. Misinformation and superstition only serve charlatans. Gentlemen, meet your ears Clipping
Seeking Wisdom » resistor color codes As a teacher, I’m always on the lookout for new and interesting ways to promote learning in my classes. As a geek, its cool to find ways to do that with technology. I recently found out about an awesome website, Merlot.org, that serves as a place for teachers of all disciplines to share lessons and information. Nick Reeder, of Sinclair Community College in Ohio, has come up with some “Challenge” games that I really like: The Metric-Prefix Challenge helps students practice and learn their metric prefixes. Test equipment is essential to troubleshooting and observing electronic circuits. Understanding and remembering resistor color codes is critical to successful circuit analysis. Another very cool tool, from David Shaheen at Owen Community College, is the Resistor Placement Game. Tools like these are great for visual and kinesthetic learners, but they are fun for almost everyone!
Ohm's law V, I, and R, the parameters of Ohm's law. where I is the current through the conductor in units of amperes, V is the potential difference measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. More specifically, Ohm's law states that the R in this relation is constant, independent of the current. The law was named after the German physicist Georg Ohm, who, in a treatise published in 1827, described measurements of applied voltage and current through simple electrical circuits containing various lengths of wire. He presented a slightly more complex equation than the one above (see History section below) to explain his experimental results. In physics, the term Ohm's law is also used to refer to various generalizations of the law originally formulated by Ohm. History In January 1781, before Georg Ohm's work, Henry Cavendish experimented with Leyden jars and glass tubes of varying diameter and length filled with salt solution. Scope .
Guitar Effects Pedals, Schematics, Stompboxes & Electronic Projects ElectronicPassion USB2-USCSI USB 2.0 Ultra SCSI Cable Adapter USB 2.0 Ultra SCSI Cable Adapter Description With USB 2.0 bandwidth, don't settle for anything less than ULTRA SCSI performance. The first and the only USB2.0 to Ultra SCSI adapter, USB-XFormer is up to 40 times faster than the current USB 1.1 adapters on the market. Furthermore, this is not just a 1-to-1 adapter. USB 2.0 is backward compatible with the well-established USB 1.1 standard. This item is new in retail packaging. Features USB-XFormer will change any SCSI device into a portable, plug-n-play USB 2.0 device that can operate up to 480mbs.
Seeking Wisdom Get the Grammar Right I had a little meltdown this week after reading about 30 of those silly pictures on Facebook that people put the funny captions on… well, they would be funny if they were grammatically correct. I just couldn’t take it any longer, so I had to post a comment. Whether you are sending a text, posting on Facebook, or writing a paper for one of my classes, taking the time to keep your writing grammatically correct is important on multiple levels. Ohm’s Law Calculators Online Some students have problems visualizing the application of Ohm’s Law and the equations for voltage, current, resistance, and power. *The use of these tools to get homework and practice answers will not help make you smarter or promote understanding! Keep Track of Your Grades This MS Excel spreadsheet can be used to set and compute grades for all your classes! The directions are on the front page and its pretty self explanatory.

Sewable Electroluminscent (EL) Wire Welted Piping- Aqua 5 meters ID: 675 - $19.95 EL Wire, also known as Electroluminescent wire is a stiff wire core coated with phosphor and then covered with a protective PVC sheath. When an AC signal is applied to it, it glows an aqua (blue green) color. It looks a little like thin neon. Very bendable, it keeps its shape and you can curl it around your finger. Its an easy way to add some glow to a project, not as bright as LEDs but uses a lot less power! This particular model is standard 2.3mm thickness EL wire, with a clear coat, pre-cut and soldered to a standard quick-connect EL wire. This is not our high-brightness EL (it wasn't available in piping form), so it is dimmer than the non-welted kind we carry. Often used for costuming, decoration, accent lighting, safety vests, bicycle/motorcycle/car/boat/home decoration, signs, etc! To use, the wire must be connected to an inverter that provides an AC supply of approximately 100V at 2000 Hz. We used EL wire to make our awesome TRON bag so check it out for ideas Please note!
