Audio circuits The following links to circuit diagrams and building projects I have found from other web sites. I have tested only very few of them so there is no guaratee that those circuit will work as expected. I don't have more info on those projects than what you can download from those sites which have the circuits. If you have more questions about those circuits then please mail the questions directly to the person who has designed the circuit or to the people responsible for those web pages.

Plastic Pals - Robots who are fun to be with! How voltage, current, and resistance relate : OHM's LAW An electric circuit is formed when a conductive path is created to allow free electrons to continuously move. This continuous movement of free electrons through the conductors of a circuit is called a current, and it is often referred to in terms of "flow," just like the flow of a liquid through a hollow pipe. The force motivating electrons to "flow" in a circuit is called voltage. Voltage is a specific measure of potential energy that is always relative between two points. Free electrons tend to move through conductors with some degree of friction, or opposition to motion. To be able to make meaningful statements about these quantities in circuits, we need to be able to describe their quantities in the same way that we might quantify mass, temperature, volume, length, or any other kind of physical quantity. The "symbol" given for each quantity is the standard alphabetical letter used to represent that quantity in an algebraic equation. What is the amount of current (I) in this circuit?

PCB's on the cheap Decent PCB's on the cheap. Version .2f (original 2003) Dal Wheeler Questions / Comments Email Me! New! Pictures of my business trip to China (6/2006) I've experimented with many home fabricated PCB methods. Toner transfer has been around for a while. 1. Basically use anything that you are comfortable with. 2. Use a gerber file viewer utility to load your newly created images. Printing from within this program as opposed to the layout software also has the nice side-effect of not having the holes included on the copper pads, giving you a little more copper / fudge room when you drill out the board later. On double-sided boards, print the bottom layer, cut out the image leaving 1-2" on one side to allow you to bind the top and bottom together. * Some have written me asking about the magazine stock that I have been using. 3. Clean off the oxide layer with a green kitchen scrubby. 4. 5. Fill a small bowl with luke warm water and a little dish soap.

Main / Home Page Physical Computing is an approach to learning how humans communicate through computers that starts by considering how humans express themselves physically. In this course, we take the human body as a given, and attempt to design computing applications within the limits of its expression. If you're using the physical computing shop at ITP, welcome. This site is the info site for the shop and a portal for other resources. Shop Policies You Should Know All people using the shop must attend a safety seminar once a year and take the safety quiz in order to use the shop. All shop users are expected to follow the instructions of shop staff at all times. Confused as to when you're expected to do when it's your day to clean the shop?

Newly Released Interview Proves That The Twin Towers Were Actually Imploded Demolition-Style, Not By The Bullshit Pancake Effect As Previously Thought! | Paranoid News - UFOs, Conspiracies and the end of the world. Get Paranoid! I know most of you believe that 9/11 was an inside job and the twin towers were actually brought down by demolition charges and not two commercial passenger jet airliners as the media wants you to believe, but there are a few people out there who still believe the attacks were legit and I don’t blame them, actually, for a brief time I believed it too. These attacks were incredibly well staged. So, for those of you who still believe in the pancake effect theory, here is an interview with two firefighters who had just emerged from the ruins of the WTC. They both say they heard a second and a third explosion just before the twin towers collapsed on their heads! Hit the break to watch the interview and be amazed by the courage of these two men. Let me tell you, that is pretty amazing. aaaaahh!!! Visit newsfall.com to read the entire article and watch an additional video: huge explosions Now, if you excuse me, I will be freaking out outside, I think the spider touched my elbow!!

Έτσι η φωτεινότητα των LED που ανάβουν κάθε στιγμή είναι ανάλογη του πλάτους του σήματος, ενώ το χρώμα αναλόγως της συχνότητας. Η ευαισθησία του κυκλώματος εισόδου ρυθμίζεται με το ποντεσόμετρο R2, ώστε σε ισχυρά σήματα να ανάβουν τα κόκκινα LED, στα μέσα τα κίτρινα LED και στα χαμηλά τα πράσινα LED. Η μονάδα απεικόνισης αποτελείται από 3 σειρές των 10 LED η κάθε μια, οι οποίες ελέγχονται από ένα απαριθμητή αποκωδικοποιητή (IC2). Δυο πύλες IC3A-B, λειτουργούν σαν πολυδονητής για τον χρονισμό του IC2, με το R6 ρυθμίζουμε την συχνότητα .
