Identifying ICs

Hey everybody, I have a bunch of ICs lying around, about 50 of them, and I have no clue what any of them do. I've googled a few of them, without great results... What I'm wondering is: Does a website exist that has just a bunch of datasheets on ICs? AND, when I search for them, what item number do I use? Most have a 2 different strings, one with 5 characters and the other with more... Thanks!

what are these ic's? Answered

I have puled two components out of an old radio/amp/ cd player etc. and i want to know what they are and if i can use them to make an audio amplifier. one says BC Power Module  SVI 3101 D on the front and 424  1w2  on the back and has 14 legs (it can be seen here, this is actually the exact one i have from the same appliance :  http://farm2.static.flickr.com/1042/4733036801_a2d72f1df9.jpg ) . The other looks kind of like an op amp, it has 12 pins and the part no 5a3920, and below that 218 130a (as you can tell i am not a good at desoldering and not having a solder suck doesn't help).

I was thinking that what will happen if we arrange inlet & exhaust valves on the piston (spark plug remaining on cylinder head)? i think that may be by using metal foam on the cylinder head the knocking of the engine might decrease. please assume that somehow i use proper mechanisms for valve timing & they dont have any appreciable effect on the piston. just consider that the weight of the valves is added to the piston. i was wondering that this might increase the efficiency of the engine because suction will take place more slowly (so it will near a reversible process, so efficiency will increase) & force of the explosion will be better. please you ppl; if anybody can give me satisfactorily explanatory answers, do reply! :)

Ice Alaska Venue

The World Ice Art Championships are held in the Ice Park in Fairbanks, Alaska. In 2009 the venue may move to North Pole, Alaska. Each team is provided with a site on a looping trail through the park. The sites are surrounded by small black spruce are double as R.V. parking in the summer. In 1999 I rented chainsaws from the blue bus for the competition.

Solar Ice Maker

Tried hunting through the 'ables, and also hunted for it elsewhere. Has anyone done an Instructable on making a Solar Ice Maker? And if not, will anyone do it? I've got some ideas for trying to use it as part of a home cooling unit, but I don't know how to make it yet. Thus, modifying it seems kind of out of the question. Thanks for any help in advance.

Ice Alaska: Ice

Ice for the competition is collected form gravel pits around Fairbanks. In the summer gravel is mined from old river channels. The resulting ponds contain little organic material. Additionally during nine month winter, temperatures range from +40 to -60F (+5 to -50C). These factors combine to create exceptionally thick clear ice. The following are pictures of an iced over gravel pit.

Ice Rink Leveling?

Looking for anyone's practical experience here. I have made backyard rink last 3-4 yr, now upgrade to Nice Rink liner. Holding water never a problem, many in Northeast last yr had limited time due to warm winter. My rink is triangle shape with legs 20x30. Slope on one side  goes from 1" to 7" or so, average ice thickness is 3-4". Part of rink over brick patio block. Use wood 2x6-2x10 borders. Was thinking of putting hay/straw under liner in the deep sections to reduce volume/depth so I can freeze solid and not have water layer under the ice. Or do you think the trapped air (under liner) will warm and work against this. I would think enough straw would not fully compress and help reduce water level, but then interface between liner and actual ground will have a lot of air space. Got a few months to think on this, my season is late Dec-mid Feb.

The Ice King's Crown

It's my take on the Ice King's crown. For the "gold" part, I first tried gluing plastic paint buckets together, but they were too thin. I ended up covering the outside of one bucket in Bondo and then cutting in the peaks with a jeweler's saw. For the jewels, I cut a positive mold for each one out of a scrap of cutting board, then pressed them into clay to make a negative mold. Then I mixed up some casting resin and red dye and cast the jewels. They were epoxied onto the crown before I locked them in with Bondo bezels. If I were to do it again, I would use a more acute conic shape and make the peaks taller. I might also use fiberglass-reinforced Bondo and try a different gold paint. If I'm real adventurous I'll cast the thing out of scrap aluminum.

Current in IC chip

Hello, It's a bit stupid to ask (I think), but essential to me. From all schematic I readed over intructables I never saw anything or anybody that cared for that. If a IC have a maximum and minimum current to respect ie: 6mA to 10mA, do we even care? Do I need to limit the current somehow? As I said, every schematic I readed never added any resistor or talked about anything relate to limiting the current on the VCC for the integrated circuit. I'm currently building a device that use one 555 timer IC in astable and a few others IC and they are all connected in parralel to the power suply. Thanks

Amplifying speakers and IC's

I have come to the instructables forum today in search for knowledge. So I have been working on a simple speaker system for my ipod shuffle, the speaker I used is quite old, but was the only one I found laying around. When I plug my ipod into the circuit everything works fine the only problem is that it is barely audible. Is there a way to amplify the sound so I can actually hear it without having to stick my ear right next to it? Pictures of my work so far will be provided. Oh also identifying the IC's included in the gallery would be of utmost help. Thanks in advance.
