sub mini fridge

I just got some soldering paste and I need to keep it cool. The temperature has to be above freezing, but still cool. Currently I'm keeping it in my fridge, but I don't want to keep it there once I break the seal (for safety reasons). I can't do that one mod using the 12 volt camper cooler, I don't have a camper cooler. I can't afford a mini-fridge. Just seeing if anyone here has any ideas. If nobody has any then I'm going to buy this USB micro fridge wwhich will keep it cool for $15.

Sub vs Carpet

So i have these, and I just thought, that since the sub's driver (is that the right term?) is on the bottom, facing the ground, and I have carpet...does the carpet impair the sub? ...Since carpet absorbs sound...Just a thought. Should I put it on top of a piece of plexi glass or something?

Best sub $800 netbook?

I'm looking to purchase a netbook, with a maximum budget of $800, I just wanted to put it out to you guys... what do you think is the best. I already own a laptop, so no suggestions there, thanks. I'm strictly looking for something small and easy to carry around and use on the plane. I'm not concerned about OS, but want something capable of at least running ubuntu, preferably XP, but I don't really want to pay extra, as I'd prefer to install it myself. I want the biggest hard drive possible, and a long battery life. I want something capable of watching video from the hard disk. I don't really care about added extras such as a webcam or card reader. With size, I want something bigger than an eee pc, but not so big that I might as well use a full sizzed notebook, something slightly bigger than a portable DVD player would be good. Anyone have any suggestions? Thanks in advance.

Source for sturdy tubes + clear stuffs

I'm going to be dropping a submersible (on a rope for now, no motors yet...) about 600 meters into open ocean. This 'Sub' will need a clear viewing window for a camera, and be sturdy enough to withstand about 700 PSI, according to WikiAnswers (apparently, one vertical meter- 1.09 PSI, right? I'm missing something, aren't I.) So, how thick/ what type of tube will I need, and where can I get it? The project is secret for now, don't ask why I'm doing it.

New car sub, does this work?

My cousin was nice enough to give me this nice little 200 watt 12 inch sub. It just needs some minor repair, theres a little puncture hole in the dust cap, simple fix. I tried hooking it up directly to my stereo and using the eq to filter out all the freq and still wasn't too happy. I took the amp out of my mirage sub and wired it all up to this one, the amp is only 75 watt rated, well I could be wrong, all I know was that the sub was 75 watt. But it works great, tell me if this is a good idea guys, lookin for opinions. Also too, is it normal that the heat sinks on the amp should be "energized"??? I picked it up by the heat sinks while it was plugged in before I had the sub and dropped it rather quickly, althought it seems to have loosened the joints up in my hand. Also too, does anyone know what brand of sub it is? All it says on the front and magnet is VR with a 12 in between (12 inch). I wanna find some specs for it as I'm not sure if the box it's in is tuned for it and I'm thinking about porting it or would that make it overdrive if it was ment to be in a sealed box?

Laser Mouse Sub-Rev Tach

I would like to use a laser mouse as a sub-revolution tachometer. I know that a laser mouse can discern 1 part in 1,000. Some can discern 1 part in 2,000. If you print a ribbon with vertical lines and attach it around a disk you could expose the laser to the lines and create a data stream. I have already found a way to increase the USB polling rate in XP from 125 MHZ to as much as 1,000 MHZ. Though I have tried to find information on how to proceed with my idea, I have thus far found little to help me move forward. Is there anyone on this list with ideas that mght help make this project a reality? This could be data acquisition on the cheap. Really cheap. :)

Too big enclosure for sub woofer?

Last year had a lot of bad luck making my bike sound system. I made some boxes, fried some electronics, etc. The boxes were too big for easy handling, so I'll make another attempt, since spring is coming. I noticed the speaker (driver) did not like higher volumes; very large excursions in the lower Hz range , probably hitting the end of its moving range. It is a closed enclosure, no port. The RMS output of the amp is probably many times lower than the RMS rating of the speaker (driver); logitech 2.1 computer amp with consumer grade sub speaker (6"). Same problem occurs with my home 10" 60 W RMS driver in a closed ca. 70 l - ca.15 Gallon barrel, with a modest 25W RMS amp: I cannot even turn it halfway up:  it is mounted horizontally, and shoots peas 40 cm (16") up! Would it be more helpful to make the box / barrel less square? Like halve the size by putting a diagonal separator in the box? Or is geometry irrelevant and does only volume matter? Perhaps there even might be a formula????

Logitech X 620 sub pinout?

Found a powered subwoofer ( Dumpster!!!) of a 6.1 computer sound system. Not the  6 smaller speakers. The front right speaker would have had the inputs and controls in it . A cable with a VGA connector had to be plugged into the amp in the back. No pinout info was found I have a similar 2.1 system (Logitech Z3), which is all I need for casual use (My real system is unusable due to neighborhood pressure...) The amp contains 2 TDA 7377 chips,and many more components than prescribed by the data sheet (some of it is the power supply)- ( Does more complicated mean better here?). 2 Options: 1) rip the TDA chips out and use one to make a 2.1 or a stereo amp with components according to the datasheet. The other one a stereo or quad for a different project. 2) find out the pinout and use the amp 'as is' (which would mean putting both all R and all L channels together (parallel?) to make a 2.1. A lot less work. (Since I am not going to use the 6.1 configuration, will the sophistication of the design still deliver?)? If anyone knows the pinout I would of course first try working with the existing circuit...

How do I power these amps??

I've got these two car amps (see pictures below) that I was given along with the sub that some people already know I have. I was thinking it would probably be better to use one of these amps instead of the one I'm using now but I can't figure out how to power it. I know it's 12v obviously but I'm not sure what to use nor do I know how to get it on in the first place, as there is a remote wire on both amps so that it isn't on draining your battery (in a car of course) while the car is off, is there somewhere I would short this lead? Again, see my pictures below.

My new monitor will work with my computer, but not my laptop, help!!?

Hi, When i say new, i mean new-hardly used, i used it a bit before moving and its been locked away a few years up till now. I got my Asus VW192T monitor out, spent an hour looking for the D-Sub cable which for reasons unknown were packed in a different box, and hooked it up. Immediately my laptop gets acknowledgement of the monitor, and the display mode changes, it now has a second monitor in the screen resolution options, and acording to my laptop, the monitor is working, however, through all of this, the monitor has remained in sleep mode, when i turn it on, it just says no signal. i spent hours changing settings, and fiddling around in the nVidia control pannel to change my laptop resulotion as well as the asus monitor resolution, restarting the computer each time, but nothing. I then go get the old packard bell computer, which now is over 14 years old, hooked it up and immediately the monitor is working, so theres nothing wrong there. In the past ive been able to connect my laptop to a mates computer via d-sub port, as it only has d-sub and i havent got a hdmi, it worked fine. Clueless, i searched for a driver which i perhaps did not have, but as it turns out, no drivers exist for this monitor, so now i am clueless. Additionally, i cant access any boot menue options in regards to the monitor, like booting in safe mode or anything, because my own laptop monitor goes black until windows has loaded, when the monitor is connected. can someone please help me out? why wont my monitor work with my laptop? the laptop is a toshiba qosmio x500, the graphics card is Nvidia GeForce360M, the old packard bell computer has no graphics card.

I just found 4 speakers and want to make a speaker box. Can anyone help me?

 I found 4 speakers (2 subs about 5 inches diameter each and 2 tweets about 2 in diameter) in a TV that was left on the side of the road.  I would like to make a speaker box for them, or a mini-amp for my electric cello.  In either case, I have very little technical knowledge in this area, and will need some very clear instructions as to what I need. I took from the TV: 4 speakers (see above) Each speaker has a red and a black wire coming out the back of it (power cables presumably). The smaller speakers are connected to the larger ones by similar cables.  There are also two more cables similar to the others, but one is white and black, the other green and black.  These connected the larger subs to the main power of the TV I think. I also took the power chord from the TV.  It has a connector that was joined to a plug inside the TV. The speakers say on the back: ZM   YD150-B1-20W-8*     for the larger speakers and ZM   YDG70-A1-10W-8*    for the smaller speakers * means the sign for ohms (my rather dusty chemistry knowledge from high school tells me this, I could be wrong, it's the omega sign from the Greek alphabet anyway) That's all I think.  I would like to know what I will need to make these speakers work, and if it is worth my while and not too expensive, and whether or not I will kill myself in the process.  I have never done this kind of project, but have always fancied the notion.  If anyone can help out, or even start me in the right direction, I would greatly appreciate it.  Is there anything else I should take from the TV while it is there still? Like the line-in plugs etc?

car audio installation

So I have recently purchased an 8 inch subwoofer from a garage sale, wich was already mounted in the box. It has 2 inputs, a red and a black. I currently have it hooked up in replacement of the stock passenger side rear speaker in my 1999 ford ranger XLT, and it works well, but is not very loud. My question is 2-fold. 1: how would I go about wireing the speaker so that it could be used in addition to both the stock rear speakers without decreasing sound quality or volume, and 2: How could I increase the volume of just the subwoofer without affecting the other speakers? I have heard that there are "bass amplifiers" that i could hook in line but have not seen where I could purchase/ build one. Schematics and links would be very helpfull! Thanks, Iloveairsoftstuff
