Upgrading wireless card? Answered

I bought an Atheros wireless-N mini PCI-E card for an HP DV7 series laptop, to replace the Broadcom wireless-G card, however, when installed, I just get a bios error "unsupported network card". I removed it and restarted with the original card and it works fine. I trhen tried installing the card live, and it detected it and installed the software, but then BSOD (my first one for Windows 7 actually), so I swapped back to the original card again. I then installed the card in the secondary bay, live, and it installed the drivers successfully, but when swapped with the original card again (the wires don't reach to the other bay), it failed to boot again. How can I replace the original card?

Video card questions Answered

I've recently gotten a free PC (a HP Evo D510) which I intend to do some moderate networked gaming on.  My plan was to buy a cheap AGP or PCI graphics card, but I'm unsure what to go with (ATI/nVidia, AGP/PCI). I've only had experience with PCI-E cards so far. From what I've read, AGP is faster than PCI.  I assume this is correct?  Looking at NewEgg, it would seem that AGP ATI cards are ludicrously better than AGP nVidia cards.  Is this the case?  The computer to be upgraded has 2 Gib of RAM and a 2.4 Ghz P4.  I'm anticipating the porcessor to be a bottleneck, along with slow bus speeds.  I suppose my main question here is what GPU should I roll with?  I'd like to spend less that $75, but that's flexible to a certain extent.  Anyways, thanks in advance.

Duplicating a SIM card?

Hi. I have an Iphone 5s with an AT&T SIM card. I will be going to sleep away camp at the end of this month. At camp, they allow you to keep your phones, but the head of the camp takes your SIM card so that you cannot call, text, or use the internet while you are at camp. This is going to be a big problem for me this summer because a lot is going on in my life at the moment, and I really need to keep in touch. I heard that it is possible to duplicate your SIM card. If this is true, I will sneak the duplicate card in. Ideally, I would like to be able to text/imessage, and be able to connect to the internet. I want to keep my same phone number. Additionally, once I leave camp, I would like to put my old SIM card in, as well as on field trip days while I am there (they give your SIM cards back for an hour on trip days.) I feel like this plan could definitely work if I execute it properly. I already have a plan to make sure no body finds out, so that part is settled. However, I read somewhere that switching between SIM cards can really screw up your phone. And b.) I heard that doing this is illegal and that doing this means AT&T will shut my phone service off permanently. I don't wan that to happen. If someone could answer my questions or tell me how to go about doing this, that would be great. Thx

How to make a RFID bracelet for a travel card (Oyster card)?

Im trying to make a bracelet which incorporates my London Oyster Card (RFID travel card) so i can just swipe my wrist and not faff about with wallets or pockets etc but I am having a few issues. The basic design is going to be simple and effective. I will have a length of regular guage wire around the wrist, secured by a single wire connector/ terminal block (see photo). It will prob be a earth wire, as it is a fancy colour. The RFID will be placed inside the plastic connector and hot glued end end to secure it and keep out the elements. The RFID's aeriel wire will be inside the earth wire heatshrink, it will be a loop of wire and can be as thick as it needs to be. I keep having problems though, I cant get the chip out of the card in one piece. I have been using nail varnish remover but with mixed results.   When/if I do get the RFID chip out of the card, i will need to solder a new aerial and I am unsure about the process. Does the length/gauge of wire matter for the function of the RFID? im thinking about its frequency. Will it need to be ceramic covered wire to avoid shorts? Has anyone put a contactless travel card into other things? Or has any experience dealing with this sort of area? I would very much appreciate any help or advice.

Replace sounds on greeting card sound module

Hello, I recently purchased this item from ebay. It's a "30s Light Sensor Record Device Module Music Box Sound Chip For Greeting Card" It comes with a pre-recorded happy birthday song. Now I want to change that song and I am pretty sure it can be done somehow, because I can see some connections available, except I am not sure what they mean and how to use them. The seller responded that there is no documentation and if I want certain sounds I have to send them the files and they will record them for me before shipping... which is ridiculous... I want to be able to change the songs when I please. The connections marked on the board say: TG1 TG2 TG3 GND VDD PW1 and PW2 Any suggestion could help.

Credit card crystal radio

What do you think about the feasibility of a credit card sized crystal radio? (Fits inside a wallet) Some possible i though so far are... A simple pcb with a diode, and a capacitor and a coil wrapped(protected by duct tape) around it. The antenna has to be tied to a hole on a corner. Or it is coiled to the card, ready to be unwrapped. The ear piece can either be external... Or can be glued to the card itself, but you must put the card near you ear... Instead of a winded coil, maybe it can be part of the pcb design itself... and to tune it, you unhook a beady wire and place it in the holes placed in a interval. What do you think? Any more ideas? In fact. a competition can be made for this idea.

a laptop sound card upgrade? Answered

Hear me out before you think about commenting. Ive got my LG R405 here, and i really like it, i added line out to it and use my sub with it. its all good, but some songs (whether the sub is plugged in or not) make my sound card cut out. (IE it'll make some white noise then stop producing sound) i have to skip the song before my sound will come back online. I was wondering what could i do to fix this? im guessing its something with the capacitors, being SMD caps, they might not be able to let the sound control chip handle the big changes in sound frequencies or something, im not too sure. dont try and tell me its impossible to resolve this issue. it is not a software problem, it is a hardware problem. i need to upgrade something, be it the capacitors, or maybe the amount of current supplied to the sound driver chip. if its capacitors, where should i be upgrading them? on the outputs or the input voltage?

Modifying a Singing Greeting Card

A while ago my wife got one of those singing Hallmark greeting cards. (This particular one played the Law and Order theme song) Well after a while it no longer played the song. I opened it up and found that there is a circuit board inside with a 3v button cell battery attached to it. I removed the board and the speaker and the battery and I'm pretty sure that I could attach wires to the two contact points and connect them to batteries that would complete the circuit and allow the theme song to play again. What I want to know is if I need to take any special consideration when putting in a new battery(s). I was going to try to just put two AA batteries in series (1.5v +1.5v =3v, right?) but I don't actually know anything about electronics and so I wanted to ask here if there were any resistors needed or if there were any differences between the button cell and the AA batteries that would require me to do something different.While we're on the topic of these cards I just thought of a neat project. Design some sort of holder for the circuit boards that would allow them to act as sort of an interchangeable cartridge. Basically detach the speaker wires and battery contacts from various boards out of various cards and design some sort of holder with contacts for the speaker and power source at the appropriate points and be able to change out the different boards. Not really practical but sounds like fun.I just thought of yet another question!Would there be anyway to hook the board up to some sort of audio cable (in place of the speaker maybe) so that I could plug these into a computer and record the song off of the board in a digital format. (Again not very practical but sounds like fun.)Anyway, this is my first post here and I'm sorry if it's a bit jumbled but I don't have a very organized mind and sometimes it's hard to put my ideas down in a succinct manner. I tend to just ramble on incessantly in a train of thought sort of manner until I think that I've said what I think I wanted to say. In closing, I like this site and plan to be around for a while and learn as much as I can. If somebody would like to help me with these ideas/projects I would be happy to provide pictures of the circuit board and pieces that I have if it's necessary.Thanks.~JoshI'm using two AA batteries. I have a wire between the positive side of B1 and the negative side of B2 and wires coming off the open ends. I tried connecting the batteries from the spot where the negative side of the button cell was to the silver rectangle thinking that that would complete the circuit and make music. That didn't work. Then I noticed that the positive connection for the circuit was actually where the clip that secured the battery was before I removed it and that the positive and negative sides of the battery were going through a capacitor before touching the final contact. so I tried placing the positive wire up on the positive contact and then placing a wire from the positive contact to the final contact but that also didn't work. I don't have any solder and have been using electrical tape to secure the wires. The wires are a fairly thin (I don't know the gauge) stranded copper. I'm not sure if the wires aren't making good contact or if I'm just doing something wrong.

Repeating Musical Greeting Card?

Hello all,  I have purchased an inexpensive musical greeting card that plays a song for 20 seconds and then stops. What I am trying to figure out is if there is a way to put a 555 timer on this thing that will send a pulse to repeat the song at 15 seconds. Basically, make it so that the card will repeat the song forever at 15 seconds so that you don't hear the fade out of the song for the last 5 seconds.  Can this be done and if so how? Many thanks!!!

What video card to buy? Answered

My old graphics cards died (two 8600 GT's in SLI), so now I need a replacement.  I've narrowed it down to either a GTX 260 or a Radeon 5000 series card, basically I can't decide whether Direct X 11 is worth it or not.  I've always been a fan of nVidia and I'd prefer to stick to their cards, but if I can get the same performance for the same amount of money with an ATI card w/ DX11 then I'd probably go with ATI.  My (original) price limit was $150, but since there isn't jack for that much, I've bumped it to $200.  I'd prefer not to go over that.  So how does the Radeon 5000 series compare to the GTX 200 series (within my price range)? Also, is DX11 worth it? My PC's specs: OCZ 550 Watt PSU (50 amps total on the 12v rails, 2 X 25A) Core 2 Duo E6850 Asus P5N-E SLI mobo 2 GiB DDR2 800 Mhz RAM 3 7200 RPM SATA drives The usual DVD drive A fairly crappy 16" CRT (1280x1024) Vielen Dank!

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?
