Using used capacitors? Answered

I have a Bose amp to fix (car), which in this case means changing out the electrolytic capacitors, as bose used a bunch of not quite sealed ones way back when. So the question is: can I just use the ones I can salvage from all the various boards I've collected, or do they need to be the same brand/grade whatever? I know about polarity and rating (i can reed!?) and can solder/desolder pretty well. I know that there may be other prob's, though the capacitor issue was well known & documented on the web. Thanks to all who help out.

Useful tools

Cheap, cordless drills are amazing tools. Take one apart and attach a speed controller, you got a motor for a robot. Also, they have good high torque motors that can be used for all sorts of things. A $50 RC transmitter and a receiver make good remote uses, such as remote detonation. More useful tools are pneumatic cannons. I've used them from pressure testing to damage testing. WHat are your useful, unconventional tools?

Electronics! What type of circuits, are needed to design a remote control flashlight.

I would like to turn on a small battery powered light by remote control. Is there a web site that sells the parts needed? Someone suggested a remote control relay would be needed. By circuits I mean a general group like PLC's.

Moving to the US? Answered

Hey there.  After I have *hopefully* gone to uni and came out the other side with a degree I am considering moving out to the USA, probably to or at least to somewhere near San Diego. Nothing is set in stone for now so any suggestions on other places would also be helpful. But my main problem is that I have started to grow some plants back in Britain and don't particularly like the thought of just leaving them, so what are the laws on bringing plants with me? I know they are just plants but it's all the time I've put into them and to be honest, they're the first few plants I haven't killed. Any tips or stories of emigrating to the US would be great. As I said, this is just a thought, but I need to know more about how to go about moving there and what happens before I can truly decide. Thanks for your help :) Tom

Moving to the US? Answered

Hey everyone. I'm rather young, but I'm trying to plan myself a future. I've though about being a programmer(I'm VERY good with both software and hardware, better than anyone else I know at my age) but I've decided wasting my entire life sitting in front of a monitor isn't for me. I want something more active, something that won't get be bored. I'm into parkour recently, and I've always loved martial arts and knives. I thought if it's possible for me to develop a military career. I live in Israel but I really hate this place(the law is very tight and sensitive about whatever can cause harm. Knives are illegal to carry, even tear gas and pepper spray draw police attention) so I want to move to the US. My English is very good, but I heard it's hard to get there. Other than that I though about developing a military career at the US army. I might change my mind, but I just wanna know how much of my plan is possible for now. Once I turn 18 I have to serve at the military for 3 years, then once I'm 21 I wanna move to the US. Once I get there I wanna sign up to the army immediately. I'm not even sure I need a house as the army provides all I need, so I can basically live there. I would like to serve at rather high-risk force(snipers, green berets, etc) for as long as I can and then still work for the army at a more passive job, such as engineering, or research and development. I know it might sound weird and stuff, but I really wanna be a soldier. Please tell me if my plan is possible, comment or correct it. Thanks, Mike.

Where to get basic materials

Anyone know a site that lists what household item contain useful materials to use in various instructables? I'm not explaining it too well but I live in a small town and can't get many of the materials needed to make things like the LED cubes, so I was hoping there was a site that tells where I can find things like LEDs, 100 ohm resistors or momentary button switches in everyday objects. like NiChrome wire in toasters or 330volt capacitors in disposable cameras.

Email newsletter relevancy

Recently the email newsletters are becoming less and less relevant. When I first agreed to start receiving them, they seemed great. I saw great instructables and a lot of good stuff. Now the featured 'ibles are all above my crafting skills and are expensive to boot, requiring 3D printers, expensive materials, and machinery that I don't have. While they're great instructables, they make me sigh and check the delete button on the email instead of clicking through to the site to view something I could actually do. I like the featured 'ibles usually, and this might just be me whining because I don't have the resources many on this site do have, but lately I've wanted to unsubscribe from newsletters - which would mean I would only venture to this site when I actually needed to do a diy project. No more neat ideas to be in awe of for their awesomeness - just complicated ones that are beyond me.  Maybe the newsletters could have more varied 'ibles? More simple ones and less "3D/wood/metal/arduino" ones? A balance would be nice.

Must have capacitors, resistors, transistors

I am wanting to know the best values/ most used values in electronics projects for resistors, capacitors, and transistors. Suggestions? Also when purchasing capacitors, ceramic vs. electrolyte? Are ceramic mostly for lower capacitance values? And lastly what is the difference between a 10k resistor and a 10 Ohm resistor. What I have figured out is that the 10k is a higher resistance value.  Thanks, diamondmine

I have a few gallons of leftover ammonium hydroxide at work. What should I do with it? Would anyone want it? Answered

I work at an engineering company and we use ammonium hydroxide for making blueprints. After a while we have to change out the bottles. I'm assuming the leftover bottles are not pure ammonium hydroxide anymore, but it is still very strong. We have about 8-10 jugs of it sitting around that we would like to get rid of. I'm not sure if it could be useful to anyone. I'm also not sure how to properly dispose of it if nobody wants it.

Best Use of Autotune

By now everyone that listens to music has probably heard (or heard of) autotune. It's been used for years to polish up pitchy vocals. Now it's more recognizable for being used on a totally different level. Autotune is the effect that T-Pain, Hellogoodbye (and by now, way to many others) use. At this point most people agree that it's way over used and just plain annoying. I have a poll to take. What song do you think actually uses it well? What's your vote for the Best Use of Autotune in a song?Mine is Woods, by Bon Iver.
