Cheap LEDs in Bulk?

I use Light Emitting Diodes for nearly every project I make. I have been looking as my receipts for the last six months at Radioshack, and found that I've purchased over 400 LEDs, and I have none remaining. I obviously go through them quite quick. Therefore, I am looking for a reliable website that sells LEDs in bulk for cheap. It is, quite obviously, expensive to buy 20 packs of LEDs from Radioshack (I've spent nearly $100), so I'd like to buy in bulk (which usually results in lower prices). Thanks in advance!

Homework Excuses thet will be the Talk of the Teachers Lounge

When you forget your homework, it's nice to add some humor to the situation and make the teacher laugh (hopefully).  Here are some excuses I came up with: "It fell into the Twilight Zone!" "My Chicken was in my room while I was doing it, and his diaper fell off.  I figured you didn't want it in the classroom, so I saved everyone the drama and chucked it in the chicken coup for them to enjoy.  Your welcome, by the way." "Well, just as I was finishing, I heard a 'er-er-reh-ah', and my paper turned into o paper figure.  Then there was a 'er-er-er-ee', and it transformed into a paper airplane and flew out the window!  The last thing I saw was a Decepticon insignia on the back.  I'd watch out.  It's a new era of Decepticons!" "My cat ate it, horked it up, and told me to clean it up.  I've got it in a plastic baggy, if you still want it." "Four penguins came into my room, took it, and told me they needed it for a top secret mission.  The leader told me 'You didn't see anything!'.  I assure you, it's being put to good use." "I was doing this outside, when this little green block-thing came up, looked at me, screamed, then blew up.  It's all ash now, so it's useless, so, I drew a picture of a creeper instead!" "Homework doesn't exist in my dimension." "Megatron stole it!  I'm telling you, I wasn't going to NOT give it to him!  He had a blaster in my face and everything!  I spent the rest of the night trying to figure out what happened, so I absolutely had NO time left for re-doing it." "I lost it in a mine.  If you want to find it, the world name is 'Procrastination'." "The neighborhood dog chased me, took the homework in his jaws, and told me 'This ain't over!'  I cannot tell you why he said that, because that is my bussiness." "I ate it.  It was bland until I added barbeque sauce." "Harry Potter turned it into a toad!  I yelled at him to turn it back, but he turned it into $1 million, and I am NOT giving it to you now!" "The TV hypnotized me into thinking it was a rabid squirrel, so I ended up smacking it into oblivion." "Function error; please define 'homework', or reboot." Please check out TheOneAndOnlyMissingNo.'s instructable on fake Windows XP error messages: https://www.instructables.com/id/How-to-Make-a-Windows-XP-Error-Message/ Its a lot of fun to make, and printing them and giving them to your teacher would be funny as well. NOTE: Realizing now that it might insult the teacher (Thanks, Kiteman), if you DO use one of these, just come clean at the end, smile, and Say "Yes, I forgot to do it.  It won't happen again."

Brushless Motor from Photocopier, what to do with them?

Hello! I salvaged these motors from one old Photocopier and i honestly dont know how to use them. Actually, my knowleadge about motors (and electronics in general) is really limited, my last achivement was building my own 3d printer from scrap materials and by doing that I learned a lot about arduino, NEMA stepper motors and associated drivers, all thanks to the awesome people who shares knoledge in this and other websites, but i am still struggling with electronics in general. So now, my question is... what can i do with these motors? Is there a way to control them with Arduino? Any kind of imput would be appreciated. I found the datasheets online but i really dont know what to do with a datasheet... Thanks in advance and sorry if my english is a bit weird, it's not my native languaje!

Control bulb with inductive proximity sensor

Please see attached diagrams in my other message below. I am using an NPN NC inductive proximity sensor (specs attached) to control a light bulb. The bulb is normally on and goes off when metal is detected. It is a 12v/21w bulb, powered by 12VDC. I have placed a heat sinked TIP120 NPN High Power Darlington Transistor 60V 5A TO-220 , a 2.2K 0.25W resistor and a 560R 0.25W resistor as shown in the circuit diagram on the right. Please ignore the left diagram for the LED. voltage readings for sensor with no metal detected: Between brown and black: 12.06/07V & -12.03/04V. Between blue and black: 0.0033V & -0.0032V (3.3mV & -3.2mV)  with metal detected: brown/black: -0.6/7mV & 0.7mV  Blue/Black: 11.96/97V & -11.93V Although the sensor is powered and detects metal ok, the bulb stays on. The polarity of tIP120 is correct and gives out heat ok. I can't figure out what I'm doing wrong so could you please see an obvious error?? thank you

Oil Central Heating - minimum amount Kerosene needed for testing it works

We have moved into a house with oil central heating that has not been used in at least 5 years and with no oil (Kerosene)at all in the tank.  We want to test if the boiler/oil burner actually works. Therefore we do not want to buy gallons of oil at the moment as we just want to test it to see if it works at all and then we can buy oil in the winter to save the expense now as it will not be in use now. A lot of companies have minimum orders however we were told we would just need a drum of oil in this instance to test it  - we are not sure if that would be enough. Is a drum of Kerosene enough? Where would we buy a drum of Keronsene?

Knex Safe (TGKTR2 Entry)

Alright! This is my safe. And a safe safe it is too! Me and a few other people noticed the irony of a knex safe, because you could just take it apart. Not so with this one! I made it with stupidly thick and Hard-to-take-apart walls, so as you would really need to work to get it open. The only piece you could break off are the pistons coming out the side, but then you've ruined the mech, and it wont work at all. However, there is a snag. The actual pin that goes into the door could not be finished on time. Everything else is here though, and I hope to get it finished up very soon. Sorry about that! The deadline sneaked up on me... So thats prettymuch it! Hope you like it. I have a video of the mechanism, but its not uploading. I should have one up tomorrow. EDIT: For all you folks bugging me to post (you know who you are...), let me give you the scoop. I am currently building a new safe. It should be stronger than the last, smaller, and cleaner. Please be patient, I will post when I can, bugging me about it wont make the time go any quicker. Thank you.

It is difficult for me to finding formulae to calculate torque and power.I want to make it process automated so that bot automatically move in rectangular area and if in between it’s battery gets down it should automatically go to charging point and come back to place where it stopped cutting when battery was down. For this which coding as well as interruption required is also a doubt for me.For all these operation which battery will be useful? And its capacity Also it will be helpful if all the components required for this project will be available from any single platform.

Advice for newbie - rotational art?

Hi there, A few years ago I picked up a lovely ornament - a crystal ball contained within a conical spiral wire thing.  When suspended you could manually spin the wire to create the illusion of the crystal ball falling (very poor explanation but hopefully you get it?). Anyway - I've always wanted to automate this, so that you can hang it up in the conservatory and enjoy a nice cup of tea whilst this thing continues to spin. My simple idea was to have the ornament hung on a basic motor (solar powered / using a solar powered battery would be even better). And that's where my idea stops.  I've searched online and remain baffled by the plethora of motors and accessories that I might need. In very simple terms can anyone advise what: electric motor I need (the ornament is probably around 1kg, I'd like it to spin at around 60 rpm?) whether I can power it via solar (ideally to charge a battery so that I can have it working at night when there is no sun!) Any other helpful tips? First time on this place - looks incredibly interesting and fun. Thanks in advance, Jamie

PC USB steering wheel 180 degrees 1080?

I've got a GEMBIRD STR-SHOCKFORCE-M Multi Interface steering wheel which I bought new about a month ago. It is pretty much "you get what you pay for" as far as it goes, and its not nearly as good (nor did I expect it to be) as, lets say a G27. Now, I have never used a G27 but I saw some videos, and it seems that it can do a full turn, while this one only does 90 degrees to each side - 180 in total. I'd like to modify it somehow so it can be rotated 1080 degrees like in a real car, or atleast somewhat more than 180. I found it useful in some racing games where turning needed to be quick and sharp, but in some simulation games it just jerked the ingame steering wheel like it were out of cardboard and ultimately I end up parked inside a wall or on top of a tree.(adjusting the steering wheel AND ingame sensitivity setting to lowest didn't help) If anyone needs pictures I'll post them later today.

How to make a double electric circuit?

First things first, I don't think the title is accurate for this question but anyways, We have frequent power cuts in the place where i live and this is pretty irritating as my modem wont work and i cant use the internet. So I have this backup generator and I got an extension from that to power my modem (The backup generator only powers specific lights). But, the problem i face is that every time the electricity goes, i have to manually remove the plug from the mains and plug it into the generator and vice versa when the electricity returns.  So, in a nutshell, i want to make a device which can accept both the mains and generator inputs but output only one of them at any time to the modem. Problems: If the generator switched on as soon as the mains went, it would be fine. But thats not the case. 1) As soon as the power goes, the generator takes about 2 minutes to switch on and then my modem takes about 3 minutes to reboot. 2) When the power returns, the generator stays on for about 2 minutes as well. So if I were to make the device I mentioned earlier, For 5 minutes I would have no internet (generator+modem starting times) and for 2 minutes I would get 440 volts instead of 220 which would practically kill my modem. Finally the device should have, (I think) 2 inputs. 1 output. A small battery or a capacitor(For the 2 min generator lag) A switch to automatically switch form generator to mains. So can anybody give me some ideas? If you didn't understand what i am trying to say, i can gladly rephrase. I thought of using a ups or something like that but i don't know how to provide two inputs and not kill the ups itself. Thanks!!

Help with mobile makerspace

We walk them through the process and at the end they have something cool and have learned something. In time I hope to get a sort of mobile makerspace started, but that is further off. I was thinking that I could get community sponsors to donate surplus materials or funds. The students at our school could help in the creation of these kits. We could have kids putting together birdhouses that have been cut and predrilled, or created a simple flashlight with an led, some batteries and a roll of duct tape.

How many strands of 17 gauge wire twisted equal a 12 gauge wire (approx)

Hi,  I need a 12 gauge wire for the positive side of a small perimeter electric fence. However the only size aluminum wire they sell locally and I bought was 17 gauge wire. My thought is to twist the entire length of two or more strands of the 17 gauge wire together to equal the 12 gauge wire (approx)  How many strands of 17 gauge will it take to do so? One more related question while I'm at it. Does the twist have to be a tight twist or can it be a loose twist? Tight meaning a lot of twists per foot, loose meaning something like 4-6 twists per foot. tia - chase -

I had spray starch in the kitchen and the weather changed here, its humid and suddenly there are flies in the house.  i dont like to swat them and leave that to clean up;  by chance i used the starch, it took some effort to target them but it worked.  i did this last nite, today the 2 i sprayed apparently shook it off were not hurt, so anyone who wouldnt want to hurt a fly could spray them with starch, put them out and there is no  mess to clean and nature can do what nature does.

Recycle Heaven

I would like to propose a new Contest category, if it doesn't already exist. I would love to see a contest where EVERY LAST PART of your project must be made from used recycled old junk. Anything can qualify, just as long as it came out of something that was previously used and must be at least 10 years old. Items could be grouped into sub-categories, electronics, papercrafts, automobiles, etc, etc. Maybe such a contest already exists, but it would be nice to see people using a little more of the old stuff. I'm seeing projects from 3D printers and arduino powered robots, and that is super cool, and I want to try those projects, but that kind of thing caters to only the techno-geek with half a life time of tools and knowledge. Most of the people who come to this site aren't that tech savy, and likely don't have a Raspberry Pi, or other Arduino mini-comp to program those super-cool projects. Lets Dumb it down a bit for the rest of us. I'd like to see more posts that can be done without having to go out for anything, unless it's to go to the tool shed or Garage for that old blender you were meaning to fix 20 years ago! This site rocks! I come here every day, and it inspires me even though I don`t have some of the knowledge. But if a project posted on here costs more than a retail version of it does, then I think the point of this site has been missed entirely.
