Sound card configuration problems

Want to configure my 7.1 sound card, which is embedded in the motherboard. Run windows 7. I used to just split the 'green' channel between my small 2.1 computer speaker system and home built full range 'rear' tower speakers with passive crossover, powered by an old 2X 100W RMS Sony amp, with very satisfactory results (movies, mostly reggae music). But finally I got a nice 10" subwoofer!  Time to make a proper setup! So I tried to plug the tower speakers in the black channel, and for now, the headphones, in the orange channel (while wiring the sub into a 4 X 40W  mono setup- Parallel , I assume????). To the control panel, sound, manage audio devices, speakers, configure (5,1 for now). Works like a charm: all tests OK, can hear all test sounds.  Restart... But W Media player, as well as other players (want to customize with Foobar_X_over eventually) don't provide any sound, except for the green channel. What am I doing wrong?

Is this the right configuration for LEDs? Answered

I am building some LED aquarium lights and I need to know the configuration pictured below will work? The LEDs are white with the following specs: Forward Voltage 2.8-3.5V, 20mA. I used an online calculator and the resistor pictured as 'R1' is 1 ohm, does this sound right? The power supply is 9VDC 800mA. I believe that if each of the 3 LEDs in a set pull 3V, then no resistor would be required, am I right? I have basic electronic knowledge, but have never designed a circuit requiring resistors.

Best configuration for an AM receiver?

Hi all. I am trying to make a circuit that would help me find lost keys. It would be a simple beeper/ noise maker triggered by AM (for simplicity). I want it to be small and, if possible, cheap. What would be the best approach? Should I use the incoming signal to 'trigger' a 555 oscillator or should I send the 'beep with the signal (The transmitter can be as big as required)? Also, most of the circuits I found online were for tune-able radios. If I want to center mine at 1 MHz and if the quality of the sound is not important, how simple can I make the circuit (while still keeping it sensitive)?

How to configure clients with WSUS? Answered

Hi!  I am working in a tech shop, and one of the things we do quite often is download and install windows updates on client computers.  The problem is that we are in a isolated area and have painfully slow internet.  I built a server with the idea of using WSUS to speed up the update process by having the clients download the updates from a local server.  I had done this in an AD environment before at another job that I had, but when I was planning this project for this job, I forgot that I had to use GP to deploy it the last time I did it, and A.  I don't want to be configuring GP on consumer computers, and B.  Most computers that we work on are Windows Home Edition, not Professional, so they don't even have GP.  Is there a way to configure my server to "intercept" requests to and just respond within our local network?  I tried pointing a DNS A record for to our local server, but for some reason it doesn't seem to work (is WSUS a different port or protocol than maybe?).  In addition, whenever I want to sync updates on the server with that DNS entry, I would have to delete the DNS entry temporarily, since WSUS services will use the DNS server on my local server no matter what (I have tried telling the server NIC to use and as it's DNS server, and also adding an entry to the hosts file to point it to on the server, but it always overrides and uses the DNS entry from my local server). Frankly, I'm not even sure that what I'm trying to do is possible.  If it isn't, my next idea was to create a script that our technicians and I can run on client computers to quickly switch the WSUS server settings to our local server and then when we are done switch them back to Microsoft.  But would that even work on Home edition computers, or just Professional editions? Thanks for your help!

XBOX 360 Network Configurations..with a twist

Courtesy of Dr.Professor Jake Biggs, I was able to be innovative with my XBOX 360 and share my dial-up connection with my 360 through my computer. (The instructable can be found here.) However, seeing as I have a unique case, I thought this would be the best medium to use in looking for an answer. So let me explain my situation. Through much effort, I was able to procure the know-how of using my cell phone (LG Env3, not the touch though) as a modem. It is able to give me 7.2 Mbps at all times of the day and night via USB. I then realized it sets it up as a dial-up connection and decided to search out a way to share that connection with my XBOX 360 so as to get XBOX Live. Thanks to Jake Biggs, I was able to succeed in this endeavor. Now I am wondering if there is any way possible to open the appropriate ports under Firewall settings in order to get an Open NAT setting rather than a Moderate one. For those of you who play XBOX Live, you know how frustrating it is to not have an Open setting. Also it would be much appreciated if someone could help me out with the IP addressing. Many thanks to any who come by and put in their 2 cents about this. I'm open to any suggestions or theories.

Is there a simple way to build a configurable TOSLINK delay?

Some TVs require 3 frames for the interpolation of tweening frames (and then there is also processing overhead time). With frames coming in at 1/24th for film or 1/30 for tv then 2 or 3 frames out of sync can look horrible and add several hundred millisecond delays. The TV's SPDIF is already delayed and works great, but downscales DTS to stereo (I hate you Blu-Ray!). So I need a delay on optical that bypasses the TV to get DTS to work.   I've done some research and found that the following products do a audio delay to help with sync problems with LCD TV (esp 120Hz) and TOSLINK on older receivers that can't add the required lip-sync delay. The consumer level delays are made by: Felston - $250 J.S. Technology (UK company) - £79  Alchemy2 - $400-$450 Primare -£200 Bottom line, what does this take to develop: A TOSLINK receiver and transmitter. A MPU that can receive the serial stream store it in internal memory and read at a configured offset to transmit. Has anyone take up a project like this and be willing to post the intructions here. I hate to buy a new receiver just because of this, that would be wasteful.

How to configure LM317T to deliver 5 amps?

Hi guys, I'm new to the site. I wonder if someone could help me resolve my problem. Well, I'm trying to build a Laptop AC Adapter, but I can't get these components right now: -A Transformer -A voltage regulator other than LM317T and I have no experience with other ICs. So I'm using a DC to DC converter. The input power supply is a Z12 Lexmark printer AC adapter. It gives a DC output current of 830mA under 30 volts (actually it's 37.5 volts, I've checked this with my multimeter). However, the output I would like to get is 4-5 amps under 19.5 volts. I would like to mention that I've already given it a try. But the output current I've got wasn't enough to feed the laptop. I've used an LM317T and adjusted the voltage with a 6.6k resistor and a 47k potentiometer down to 19.5 volts. If there is a way to boost up the current with a joulethief or using a set of transistors or parallels LM317Ts, please tell me. Also, I hope that you give me the part number of all the components to match up with the LM317T because I must use this type of regulator. Thanks for your help and please consider my situation.

Change batteries from serial to parallel configurations with switches?

I have a 5s4p battery pack.  The cells are 3.7 nominal voltage lithium ion cells.  In a serial configuration it is 18 volts nominal.  If I wire it in parallel it is in a 1s20p configuration and 3.7 volts nominal.  I had this awesome idea to use switches to change the configuration from 5s4p to 1s20p.  I want to do this because then I could charge whole pack with a 3.7 volt charger.  Better yet, I would not a balance charger. Once I got to trying to design the switch configuration I was amazed at how complex it would have to be.  The only way I can think of at the moment is to use 4 single throw single pull switches to isolate the cells and then use 5 double pole single throw switches to connect all the pos and negs together.   Does anyone out there know how to make a circuit which could work with with one circuit board and one switch?  It could switch between 18 volts serial to 3.7 volt parallel? Thanks

Tesla coil configuration. Audio amplifier power supply?

If I am to use an audio amplifier as a power supply for a Tesla coil could I do without a spark gap and primary capacitor? I will be operating the coil within the audible spectrum (1Hz - 20KHz) so an amplifier fits the bill. It's a 2 channel magnetic field power amplifier rated for 750W per channel. That's 750RMS not 750IFL. (If lightning strikes) The current would flow as follows: Power Amp> 4ohm Load> NST 5000v 60ma> RF Choke> Primary Coil> Secondary Coil 1. Do I need a capacitor bank between the RFC and the primary? 2. Can a few feet of 28AWG galvanized steel wire act as a reliable resistor for the 300W current? What about 750W? If not, what can I substitute? 3. Can the amp hold together? I need it in one piece. Please point out the flaws. Thank you

Yes, it is the only shotgun rubber band gun that I know of. It is based off of the Remington M870 and can be easily modified to be both be in an entry shotgun configuration, with tactical buttstock, or in a "Breeching weapon" configuration, with no buttstock. In the first picture, it is in the entry configuration. In the second picture, it is in the breeching configuration, but with the buttstock shown to show how it could be carried in a briefcase or something similar. There is no difference whatsoever between the two, other than the obvious difference in the buttstock, but less obvious, the breeching configuration has more mobility in the cocking hammer, so it works better. I am sorry for the lack of pictures of the internals, I will hopefully be posting them in the future.

How to prevent transistor saturation?

I am trying to create my own audio amplifier. My problem was when i have large signal amplification the transistors becomes saturated, as a result the resulting signal is already clipped. This problem usually occurs when i use a transistor at CE configuration. Using CC configuration prevents this saturation problem but it also makes amplification very hard. When i use CC configuration one of the two transistors becomes "useless" because collector current becomes very low and based on further analysis it seems like only the last transistor is doing the job.
