Question by R.A.T.M | last reply
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.

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?

I had the idea to put a sub in my car. i bought everything (sub+amp). But first I tried to wired it in my car, my friend told me to look at my alternator to see if he could take the load. My amp and subs are 600W rms. So I,ve look at the specification of my car....my alternator is an 80 amp. Its the only thing about alternator I saw in a lot of diffent specs.\ So. 80 amp alternator 600W rms amp 600W rms sub Could my alternator could take the load???? thanks!

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.

I'm looking for or to make a 100 watt amp, I can't seem to find any. If you know where i can find one online or a schematic to build one please let me know! Also is it possible to resist or lower the amps from an amplifier or will I have to specifically get a 30 watt amp for the mid range speaker. I am attempting an "led music box on steroids" project hahaha.... basically what I am going to do is make a clear plastic box and put leds and speakers and a 6" sub in it. Kinda bored and looking for a fun project and this came to mind. I'm open to any suggestions to make it better or ideas on how to power the speakers. Thank you in advance! The sub woofer I'm looking to power http://www.electronix.com/100-watt-woofer-speaker-ohm-p-13521.html and the mid range speaker http://www.electronix.com/30-watt-midrange-speaker-p-13507.html Might think about putting a tweeter in too

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?

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. :)

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????

Well, I recently built this mag loaded SMG, but it is technically just a short version of Blue Mullet's RGMP. Tell me what you think... Pros: 40 ft. range Comfortable Cool looking Making an extended mag would be easy Fore-gripis included Is a fantastic gun for a push trigger (a gun where the FP pushes the bullet against the trigger) True trigger Cons: Handle is only comfortable when the mag is inserted Bullets only work well when a broken rod tip is inserted Could use a stock

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...

Question by unbottled19208306 | last reply
I want to add a sub woofer to my stereo system. The sub woofer is one made from spare parts. It consists of a twelve inch speaker wired directly to binding posts. My problem is that my amplifier only has four binding posts, these are a positive and negative for the left speakers and a positive and negative for the right speakers. I am not sure where to patch in my sub woofer. Thanks for any help
Question by nurdee1 | last reply
I have a Phillips SW 900 powered sub-woofer. The internal amplifier board has broken and I need to get a new board or an equivalent amplifier. The internal subwoofer is a 6 inch 4 ohm 40w driver.I don't want to spend any more than around 50 US dollars. The only connection that I need is one RCA jack for audio input. Thanks.
Question by nurdee1 | last reply
I have a powered sub-woofer that had a blown speaker and being that I spent the money to get a better one I thought that converting the old sub woofer amp to use for my guitar would be a good idea. I already have something to practice with but making something that can be used for gigs would be great. However, I'm not an avid or experienced electronic wizard and will need the help to complete this project. Here is the info I have on the amp itself; OUTPUT POWER 50W (4 ohms,DIN) THD 10% @ 55Hz Reproduction Freq. Response 45Hz - 150Hz Phase Switch 0, 180 degrees Input Sensitivity (Sub In) 460 mVrms AC Power 120V/60Hz Power Consumption 70W (at 1/8 rated power) Standby Power Consumption <6W What I do know that I need is a 1/4" mono plug jack and being that the input for the woofer is mono putting that in shouldn't be a problem. I'm mostly concerned about the frequencies that the amp will handle for playing a guitar and speaker recommendations. Plus any other opinions will be appreciated. I am expecting this to be a clean sounding amp and as it sits will only provide volume. An EQ is planned to be used after this amp is put together and then eventually an overdrive. I'm planning on connecting 2 50W speakers and wondering if I should hook them up in serial or parallel. With the help of my fellow instructabl-ians I will be able to post my 1st submission.

Question by joef07 | last reply
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.

Question by slimguy379 | last reply
I`m making a dac+amp with usb input and headphone out. I`m powering it from USB. The USB controller and the DAC uses 5v and 3.3V, but the opamp(LM4562) uses +-5v. How could I get this differential voltage form the 5V of the USB, even if i get less current. If you can give me a good IC, it would be great, but if you can give me even a schematic (+IC) would be awesome.

Question by praveenpal
Well this is a little something I put together mainly for show, but also for my grandfather who wanted a full auto tommy gun! Ever since knex war 2013 he thought the Mepain's shotgun turret was a tommy gun and he thought if he got it working correctly it would be full auto and mow everyone down! Little did he know, even due to my best attempts at explaining what it is, how it works, what knex guns are actually capable of doing as of this year, he still full out believed that the tommy gun would destroy everyone. Well now his grandson has built a full auto M1A1 Thompson for show and tell this year, and even though it's very war pratical or strategic at any war scenario, it does show how far we really are from full auto weapons. Although we're an innovative a we will figure it out... eventually. So let's keep up the good work and keep innovating! Now, let me quickly tell you how it works. It's priamarily based of King Louis XIV's full auto mechanism, which is also used in KILLERK's current project DAM. So my version is more closely related to DAM because it's trap based mechanism, you pull the trigger and a little arm pushes a gray connector out of the way, the hatch opens and gray connectors come flying out at a range of about 20 feet. So nothing new or super innovative, just another spray and pray weapon. Special thanks to Zombiekiller for making the ible for the body, without it I wouldn't have been able to pull of such a good looking Thompson, mainly because I am not a replica maker. Zombiekiller makes a lot of great replicas just waiting to be made into shooting knex guns so I highly recommend checking out his ibles if you haven't already. Alright thanks for checking out this forum! feel free to leave your thoughts and opinions in the comments below! JonnyBGood

Looking for some headphones to replace my Skullcandy buds that broke... I want something with great bass- something that really punches. Preferably with inline volume control- I am using an ipod touch (really love the volume control). I have a pretty small budget, around $20 is my goal, but as I am not an audiophile, they don't need to be perfect :) Just in ear headphones with great bass.
Question by astroboy907 | last reply
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.
