"Standard" Crystals? Answered

So, I was browsing the electronic goldmine today, and I came across these. What do they do and how are they used? Do you apply voltage to the leads and it emits rf in all directions or what?

Standardized Electronic Components?

Hello all, I was just wondering about finding electronic components. Some parts, like resistors and capacitors, seem pretty easy to sort out as long as you aren't looking for something out of the ordinary, just find the values you need rated for the wattage, etc. However, in the case of transistors and things like that, I am always seeing many different numbers (people say "a such-and-such transistor, like a {serial number}". Is there some general standardization for these parts? Or at least, some nearly universal sourcing that is considered a "standard"? I only wonder because trying to find components can be a real pain. I have a transistor, I know it's an NPN Darlington transistor, but that's about it. Others that I have salvaged I don't even know that much about. Any explanation or links to sites that explain these things would be much appreciated. Thanks in advance for any help!

Instructables: Quality Standards

I was thinking..... as I do. Quite a few of instructables, on.... instructables, havn't meet the quality standards of a good instructable, let alone get featured. Why do people bother make instructables 2 steps long? Wouldn't they like to be in the newsletter and get nice feedback? If you put all you effort in to an instructable you will get repaid with nice comments (normally). I wouldn't like to see instructables as a website with few featured instructables lots of quick put to gether nonsense. I would like to see quality, and a archive of fun things to do and make for all the family. A while back a published an instructable called 'professional water rocket guide'. I spend along time on it and was pleased with my self when it got featured, and it was in the newsletter. This it was gives me motivation to do good instructables. What do you think about poor informative an qualitive instructables? Thanks

LED wiring standards?

Making a wooden rangehood for my wife for our annivesary, and I want to use LEDs  for the light source. I wan to use 3 banks of 30 lights in each 4X8" oval space, and from what I have read it would seem to better to wire each set in parallel. My question is, do I need to put a resistor on each LED to adjust the voltage to the proper amount, or (since it is wired parallel) will one work for all?

Knex Firepower Standard

Hello everyone I (like alot of my freinds) get tired of... oh why dont you just search "Knex gun" and look at the mini descriptions and read them all, or maybe most and think what alot have us geting tired of, Go ahead! see you in maybe a min or 2? just click back or whatever to return here! and continue from where you last read.Welcome back! Do you see what what I'm talking about? well there are two things and if you did not notice these things feel free to look again!And what is Sypran talking about? (drumroll) the Quotes "It's very powerful" "easy yet powerful knex gun" "gun shoots about 60-70 feet" "this is a very small gun but will fire about 50 feet" "A deadly knex gun" and that is just the first page! i could go on for hours (ok maybe a long time) of coppy and pasteing these quotes!honestly i see to much "easy yet powerfuls" i cant realy tell what is powerful! so what do we do? well we take out time building maybe some and it turns to be not that great or it is great!, or we rush to see if KILLERK, Mepain, Extreme builder, Trainman2000 (i will always call him that >=D)You (aka mykhailo),Perfect duck,loosewire,Dsman19(i cant rember numbers) Oodalumps, am i forgeting anyone? (tell me if i am) has any new ideas/guns.so what do we need to do? WE NEED A FIREPOWER STANDARD something simple like 1-20 and how to mesure it, in earth science they clasify rocks hardnes by what they scratch (nail 2.5 glass 5.5 and so on) we need it something like paper peice, but not that for some guns have alot of power but cant peice due to low velocity and or dull non sharpened bullets.also if you know anything about real guns the bigger the bullet, the more powerful =D but the smaller the bullet the higher peirce rateing (a 0mm would be the best peirce but little damage) so in other words the biger the bullet (45 cal example) the more stoping power it will have but less muzzle velocity (pierceing ability) wile the smaller (7mm) the knocking over/stoping power is anything to be desired, but it will have high muzzle velocity so peirce through more materials. yet with (if it was at all posible) a 0mm (or basicly nothingness) in theory could peirce through ANYTHING but would not stop the person or thing in any way so the same pricable stands for knex notice the shotguns that shoot conectors (or killerks magnum with his amo) create a biger bang sound, they do more damage, but need more force to get all that mass through a paper wile the ones that shoot sharpened (like gorkem's) or greens can peirce paper with ease. so not only will we need a firepower test but a peirce test. peirce is easy enough its velocity and ammo size and a variable if it is sharpend and we have an instructable on how to determin bullet speed. power is bullet size+ extentions (killerk's magnum ammo like) also a little velocitybut the system needs a ruberband standard to keep in mind no putting on more then the systems amount of ruber bands or size of ruber bands (i know people will do this anyway)so what am i basicly saying in this topic? easy please people we need records of bullets speeds for sertain bullets with your guns it is easy since most of you seem to have digital cameras and there is an instructable about it. also we need to know a standard RB cause i dont know whats standard in the rest of the world besides USA and even then i dont know if its standard in the other states (they say americans like everything bigger and sadly sometimes it's true)i have tested some guns out and lets say that stong yet easys from the first page so far are low... so maybe we need a test for difrent kinds of guns! i have seen rifles that fire like a medium pistol (for they are exept they have a longer barrel, bipod, stock, and scope) should these even be given a 6 out of 10 in every catagory? or should it be 2 outa 10 for rifles. if lets say we got a standard of ruberbands to be 2 (not including trigger ruberbands) that where (makeing this up) a circumfrance of 3 inches, end of barrel being 2 feet away from camerathe adverage gun (all makeing up still) 25 feet with white shooting 1 foot per sec, does not dent an empty can. bullet speed of 5 feet per second with a max range of 40 feet (acurate ranges ppl use mesuring tape) with a white bullet that dents and peirce through an empty can we can conclude that the gun has high peirce rate but beter then normal power rateing. so a 7/10 for peirce if best was a max of 60 ft bullet speed of 10 ft per sec and white rods then it could have scored higher.one day when i search "knex gun" i want to see "my first Sniper!, it scored a 7/10 firepower and 8/10 pierce with 100ft range" cause then i can say that is a good gun I'm going to build!

Knex Gun Force Standard

The problem is that almost no one has enough room inside to shoot a knex gun unless it's a total peice of ....you get the point. But, by going outside there are many other vaiables that effect how far a gun can shoot (eg. Wind direction/ speed, trees and other obstruction, etc.) Also power as in "can shoot through can" or "through 3 sheets of hard cardboard" can also be misconstrude in the way that range from the can is a main factor, point blank range is not always the most powerful range, often 1-3 inches away has exponentially higher power. What needs to happen is a tool be built (out of K'nex, what else?) that is not only easy to use but impossible to mess up, it should be able to give 100% accurate reading for all types of guns from the weakest to the most powerful. Also in terms of different types of ammo, rod size shouldn't matter( thats what she said) the only thing that should matter in terms of ammo is whether it is deer slug, rod, sligshot/ catapult rod(a rod with something the can grab the elastic), or other and specify what that is.Range is all to often streched beyond reality by saying it can shoot 200 yards, when really it might be able to shoot 50 yards tops when pointed strait but 200 yards if it is pointed strait at the sky. We need to bulid a target that you shoot from maybe 5 feet away and something mesures force, be it cardboard, or cans, or plywood, maybe even something that leaves a dent in it and you can mesure the depth of the dent to tell you how much force (eg. 1/2"=1, 1"=2, 1 1/2"=3, etc.)Also one last idea if you would prefer to stick to range outside, is that you divide the range in feet, by the number of cardboard sheets(or other medium)the gun can shoot trough at point blank range (say it shoots 63 feet, and through 4 sheets of thick, corrugated cardboard the equation would be F= 63/4= 15.75, so your force rating would be 15.75)These are only some ideas to get all of you thinking about a standard in K'nex gun power.-TheXenk

Standards for being featured dropped?

This is anecdotal, since obviously I don't review every single featured Instructable. I just happened to notice two recently that have some nice photos but otherwise seem kind of "incomplete". Absolutely no offense meant to the authors, I'm sure they put a lot of effort into these projects, but the documentation seems lacking and not up to the standards of "someone should be able to reproduce the work": https://www.instructables.com/id/Colorful-LED-Christmas-tree-automaticlly-flashing/ https://www.instructables.com/id/Functional-Nintendo-Controller-Coffee-Table/ The latter especially has nice photos of what is obviously a really nice build, but totally lacks a materials list, wiring diagram, cut instructions for the wood - all information that's essential to actually do the build. There are a couple (nice) comments pointing this out. Just wanted to point this out - not sure if there's someone new on the community team who might be featuring things just because they have nice photos, without checking the text, or if there's been a change in the standards for featuring that I'm unaware of.

If i had an guitar, could i change the first 4 strings to bass stings and take off the last 2 to make an bass? Answered

I recently picked up a full sized acoustic guitar from some place that was by the road. So i fixed it up and put all six new guitar strings on it. But i figure since i have an acoustic guitar, as well as an electric guitar, already, i might as well make the junker into a acoustic bass guitar. Would it be as simple as taking off the last two strings and putting on four bass strings instead of guitar strings? What is the standard tuning for bass? And one more question, if i sanded down all the frets so they were flush with the fretboard and then refinished the fret board, would it then become a fretless with the lines so i could tell where the frets were if i needed them?

Creating a New Standard for Rating Project Difficulty

Hey guys. I've worked on many projects based off of instructions given by another person, and I've seen many different ways of ranking the difficulty of a project. What I've found is that many of these difficulty systems are hard to understand or don't provide enough information. I think that Instructables could really be improved by a standardized difficulty ranking system to help users quickly decide if they have the appropriate skills and tools for a project based upon a search criterion or "arrange by" feature. The system that I have come up with is based upon two factors: tools and individual skills. Tools would be the main focus with the skill level based upon the viewers' ability to use them. I won't go into too much detail now. I want you guys to give your honest opinion on how the system should work before I try to finalize my ideas. Keep in mind I want it to be simple, but descriptive enough to help us decide if a project is feasible. It doesn't have to be too accurate, so don't make it more complicated than it needs to be. I think that it should be voted on by the community as well as the author. Thanks guys. I look forward to your input. If we get something good, maybe the Instructables staff can incorporate it into the website's features.

What could go wrong in a standard garage door opener?

Hello there, I have been asked to try to repair a malfunctioning garage door opener. The man who handed them to me said all of the modules work for a few weeks, then suddenly stop working. I opened them, looking for any burnt component, dry solder joints, tested relays in search of a stuck one, but could find nothing. I tested them at home, and they all reliably clicked their relay on and off, as expected. So the question is, what would cause ordinary garage door openers to fail? I thought about a bad powerline (circuits are 50's era in his building, and have never been redone), but have no means to check it. In the same direction, I was looking for a different model garage door opener, and only found two alternatives: one is the run-of-the-mill SkyLink stuff, expensive, reasonably secure, the other is the dirt cheap Chinese-made remotes with no hint about security. Since this is Instructables, I looked for garage door opener projects, but most are so-called "smart" and need a reliable Internet access, both on the smartphone and on the receiver module. Since this is a multi-tenant building and my country is known to be among the most expensive for internet access 1. there's no easily accessible Internet in the garage 2. drivers can't be assumed to have a smartphone and even if they do, 3. Internet access on a cell phone is extremely expensive. The other question would then be: have any of the community members here saw a garage door opener that would: 1- only need easy-to-make RF remotes? 2- be at least as secure as the original SkyLink? 3- require no Internet access?
