Where can I get cheap LEDs?

I need to get some cheap LEDs. I want to get 3-5mm bright white LEDs, I want the bright ones that are used in flashlights. I also want long wires so I think I need to get them from a component seller and not try to salvage them from a flashlight. I have found some places online that sell them cheap but the shipping is gonna kill me. Is there anywhere that I can get them that has free shipping? Does anyone know any companies that will offer free samples of LEDs? I fon't have a company or company email adress. Any help will be apreciated. Thanks.

How do I make a cheap automated drawer?

I want to build a simple headboard for my bed and have a vertical drawer pop out from both left and right. How do I build an automated pop-out drawer, especially on a (relative) budget? I was thinking of having basic springs attached to the back of the drawers to push them out constantly, only to be kept closed by some locking mechanism that opens the drawer when stimulated by a switch.

Cheap sources of stuff to build/modify.

In this thread, share your tips for getting the materials, supplies and tools you use to make and modify stuff as inexpensivly as possible.A trick I use:The local grocery store "Hardware" section is full of cheap tools and supplies. Last week I picked up a 105 piece screw/nut set in a nice divided plastic clamshell case for $1.00, two days later I saw a similar, but empty, plastic case selling for $3.99 at the craft store. The screws at the local Big-Box home improvement center would be about 6 cents a piece + the gas and agravation of driving to the store in the middle of a project because I need a couple 6 cent screws. 6 cents x 105 pieces = $6.30 worth of screws.

Cheap High Speed Camera

I've had this idea about a cheap high speed camera using say 10 of those small action cams, like this: http://www.ebay.com/itm/New-Worlds-smallest-Video-Record-Helmet-Camera-DV-DVR-black-free-shipping-/180766403888?pt=Camcorders_Professional_Video_Cameras&hash;=item2a16846d30#ht_4895wt_952 What you would do is hack the Start/Stop switch and hook it up to some sort of controller that starts each one of these 10 cameras about  3.3 milliseconds before the next one, thus having each frame from all the cameras to be 3.3 milliseconds apart from each other, which is 300FPS at 720p for $158. The cheapest HD 300fps camera....   EVER, not that i can make it. The cheapest equivalent is around 2K.

Cheap but powerful option for a go-cart motor? Answered

I'm pretty keen to build a motorized go-cart with my friend, but we both have run out of chores to do for money, too young to get a job and are on a pretty low budget. We've already got a go-cart that doesn't have a motor, but is well-built (welded frame) and has a proper steering mechanism (not just rope attached to the front axle). Two questions: Would it be easier to make an entirely new go-cart or to adapt the go cart we've got now to suit the engine we get? And What's a cheap option for a motor that has some torque and can go around 40-50km/h? I'm talking cheap like under $100NZ (around 70$US I think?) EDIT: PLEASE DON'T SAY BUY A LAWNMOWER ENGINE UNLESS YOU CAN GIVE ME A DETAILED DESCRIPTION OF HOW TO USE A LAWNMOWER ENGINE ON A GO-CART - Lawnmower engines have vertical driveshafts, and you can't just tip them sideways. A V-belt is not ideal.

Cheap Island Building possibilities

Hello! Ive been doing all kinds of research and planning on making man-made islands for a few years now, and I had a thought on one method inspired by Thinkenstein's Instructable on Trash Rocks. He has been able to make floating rocks using plastic bottles filled with air, nylon fishnet bags, and covering the combination in cement. Tadaa, Floating Rocks. But after seeing his instructable about this, would anyone think it to be possible to make a large floating land mass using plastic bottles of 16oz and above, nylon fishnet bags, and cement? I think it sounds doable, but that's just whats been put on paper.

Sensor to measure weight.

Hi everyone, I am stuck. I am trying to find a method or sensor to do what I want. Basically, I am trying to make a cheap flat weigh scale- light weight , flexible and portable (carried in a brief case or lap top case); thinner than using load cell sensors. I was hoping for a flat compression fabric , foam or piezo resistive pressure sensor, but have not found what I was looking for. It needs to be able to measure 50 to 250 lbs & fit on a counter. Does something like this even exist? Any suggestions would be most welcome. Thank you Appl314
