Use Output as Input

Hi ! I have this program, Finale 2005b. I've searched everywhere, and I cannot find any way to export the music I produce in there as a real audio file (NOT a midi). So, to achieve this, I have decided to record the output as the input... using Audacity , actually. To do so, I used a simple mono cable to go from my headphone to mic plugs, and set the volume to the minimum... to avoid too much amplitude going in. Now, for the use I want it, this method is way too dodgy (plenty of interference, specially each time I move the cable 1 mm...) I'm pretty sure there is some program or solution to directly map the stream around... I don't have much funds, so free would be good, and btw I work on Win32. Thanks

Infrared Variable Output? Answered

I am trying to wire some infrared LEDs to an Arduino. Problem is, the signal from the infrared LEDs has to be able to change variably, like from a potentiometer. What I mean is, I am aware you can read an ouput from an IR LED, then use the Arduino to replicate this and consequently control things, but what if I wanted to ouput a signal that changed, like a potentiometer? Basically, I would like to be able to control some motors speed through PWM by a potentiometer, but wirelessly. I'm not sure if this is possible, and if it is, is there some information I could look into? Any help is greatly appreciated.

Consistent output with arduino

Hi guys! I have a little project that i could use some help with. I am quite new to the arduino, and not that steady in the code, but im hoping on getting there! The project im building is a litte controller that drives a relay output. The controller is connected to a photo-cell that has a two pin output. This output is shorted at various times depending on the movement in front of the photocell. What i need is for the arduino to close the relay for the same period (say 0,5s) each time the photocell circut is closed. And maybe block a repeating signal from the photocell within 0,5s Is this possible in some way? Any help much appreciated!

Specific output of current? Answered

I'm getting a little more knowledge about current measured in mA, but it's still all confusing. From my understanding, your project draws the current needed out of your battery. If my LED uses 25 mA, then the LED will be sucking 25 mA from the battery. If I have two LEDs, then it would be sucking 50mA from the battery, thus reducing its life. So, based on that, how can wall warts have a specific output of amps? How can a wall wart put out 1000 mA? If you use a project that only takes 700mA what happens to the other 300 mA? What if your project use 1,500 mA? And. . . How do you measure the current being pulled through a basic circuit and your average 555 circuit? Thanks,

Magnetron output power and design? Answered

So I've been looking into the design and operating principles of cavity magnetrons and I have some questions that I can't find answers to. What exactly determines the output power of a magnetron? Is it just a matter of how much voltage you put in and if so, is there a limit to how much voltage can be put in? If there is a limit, what properties of the magnetron set the limit? If it's not that, than does the output power have to do with the number of resonator cavities the magnetron has?

more output current with LM317 ?

Hi, for some time I have been wondering if I can make LM317 to output more than 1.5Amps. After many hours of searching I found that I can achieve this in 2 ways. The circuits are in LM317 datasheet which can be downloaded from here : http://www.ti.com/lit/ds/symlink/lm317.pdf 1- By using a transistor with LM317 (page 16) . 2-By using several LM317 regulators in parallel and using TL080 (page 15). Second one seems better IF load is equally divided between regulators, it also has the benefit of producing less heat when  high currents are drawn. My question is: will the second circuit (LM317s in parallel) work and output more than 2Amps? is load equally divided between regulators in this design ? can I replace TL080 with another IC ? By the way, there is a circuit in page 12 called "tracking preregulator" , what is the purpose of this design ? PS. I know there are switching regulators which output more current, but I'd like to experiment with LM317.

Measuring a Bluetooth modules output? Answered

There is a serial Bluetooth module that I have used before on an Arduino project but now I'm trying to use in a project without the Arduino. Basically I need it to be an electronic trigger, I don't care really what the signal is just how long and the voltage and current. There are 4 pins on the module: Vcc, GND, Tx, and Rx. There are 2 open pads: Key and State. When I send a command from my phone the module sends a signal out the Tx pin, and it is this signal I would like to measure so I can pick a command with an appropriate signal and tailor the rest of the circuit accordingly. I tried a voltmeter between Tx and GND but saw no signal on any level measuring DC. Is there something I'm missing? Is the signal more complex or different, or is that test setup flawed? I tried other combinations, Rx-GND, Tx-Rx, RX-Tx, GND-Tx, GND-Rx but saw nothing.

The "latch enable" pin is grounded. Both output pins are not connected. Why doesn't Q(inverted) go to 0.3V and Q to 3V, as the datasheet suggests?
