Where is a rainbow? Answered

As you may be aware, your reflection in a mirror appears to be behind the mirror. But, where is a rainbow? The Sun is over your shoulder, the cloud of raindrops is in front of you, but what is the apparent location of the rainbow? Is it between the observer and the water droplets, in the same location as the water droplets, or behind the water droplets (from the POV of the observer)? Or is it at some indefinably infinite location? I should know this... (a sketched-out ray diagram would be greatly appreciated)

Midnight Rainbows

MIDNIGHT RAINBOW: It could only happen around the summer solstice. "I recently witnessed a 'midnight rainbow,'" reports M-P Markkanen of Kuusamo, Finland. "It towered high in the sky and lasted from 10 pm until 3am local time on June 12th." He captured the moment using a Nikon D80: A rainbow at midnight. How can this be? Simple. Kuusamo is on the verge of the Arctic Circle, and at this time of year the sun never completely sets. Hanging low in the midnight sky, it shines up on distant rainclouds, creating a remarkably tall rainbow. "I guess you couldn't see a rainbow much taller than that," says Markkanen. "It was a clear sign of the coming solstice!"  So who here from Finland had a chance to see this amazing sight?

Rainbow vac for dremmeling?

Is this a good idea or no? I'm sure a few people on here know what a rainbow vac is, and it has the suction to work (although I try to use the low-speed mode if I can because it's a loud vacuum). I emptied it today however and there was metallic crap EVERYWHERE on the inside of the bowl. It wasn't that bad actually and washed out with water. But I was wondering, should I maybe use something like some dryer vent and make a plate to fit into my window?

Rainbow Play Systems - Tube Slide Instuctions/Help Needed!

Hi all, I recently acquired a used 360 corkscrew tube slide that was a part of a Rainbow Play Systems playset. I'm planning on building a fort/play/swingset for the kids, and attaching this slide, but would like to find the original instructions so I know the proper deck height for the installation. Also, it seems like each of the slides 6 sections have the bolt holes labeled (A, B, C, D, etc.), and I assume that they should all be aligned (A with A, etc.), but this isn't the case for each section. Perhaps the previous owner put it together wrong, or perhaps there are different alignment configurations based on the deck height where the slide will be installed and/or how extreme the drop in the slide should be. If someone has one of these sets and slides, and can either share the instructions, or even just look at your slide to see how the letters are aligned, it would be greatly appreciated. Thanks! PS - Here's a link to the slide: Option 19F - 360 Tube Slide http://www.rainbowplay.com/options/

I saw this yesterday and thought it was pretty COOL...

I went out to the car yesterday at around mid-day and saw what I THOUGHT was the light of the sun refracting off the trunk lid of my car......I WAS WRONG.     I looked up into the nearly cloudless (except in one area) sunny sky, and saw two large clouds "near" each other; with a HUGE bright rainbow in between them. This is the first time I have EVER seen a rainbow in a sunny, rainless, snowless day. Below is a Close up and a normal sized picture of the bow.     In the second picture, there is a speck up there,  that is a crow, IIRC.

So.. I got Married on Saturday. [update]

  Update My Wife and I, would like to say thank you for all your kind messages. The sun is shining over the mountains, we have an amazing cottage with crazy wobbly oak floors, and we are both very happy. I am hoping to get some pictures blogged up on here, both for you all to enjoy, but also to link to my family. Most of you already know, but tomorrow I am getting married. It certainly has come around alot quicker than I expected, but I did expect it to do that. The ceremony is at 11.30 in the morning. Then we head off on our honeymoon to the Lake District. I am really excited, and can not wait. I have just finished packing all my gadgets,  now I need to start packing boring things like clothes and such. We are taking the internet with us, but mainly so we can do a little geocaching, and keep a keen eye on the weather. So, wish me all the best, no doubt I will need it. Having said that, I am not one bit nervous. I intend to get ready early enough to squeeze a Left4Dead game in before the ceremony. The downside is that you will see little of me, the upside is, we are hoping to do a 'How to get married' Instructable, after that, I intend to use my new found space and freedom to beat Kitemans 100 Instructables In less than 6 months.

I want to make an RGB LED microlight that has multiple modes for which it flashes with PWM. rainbow fade, slow/fastblink

Http://www.youtube.com/watch?v=Sqq0doh7Dto I want to make my own version of this. I'm willing to do whatever it takes. Can someone point me in the right direction? Its has to be a small portable flashlight and run off of small batteries. It has to have multiple modes: one of which is a rainbow fade, another of which is a super fast blinking mode). I understand Pulse Width Modulation achieves this, but I've only seen LARGE circuits that achieve this in comparison with the size of a microlight. I don't think a 555 timer circuit would work for me since it would be too large and I would need 3 to controller the RGB. I understand that microcontrollers are needed to control the modes, what type of microcontroller could i use that is that small? If filmed under time lapse, I want to achieve the effect in the picture for a mode: http://lightzombies.com/store/images/Blending%20Rainbow%20-%20White%20Blue%20Green%20(1).JPG Any help is very very welcome.

A "Drawing Board"

I came up with an idea! There should be a place on the site called the "drawing board" in which you could sketch out ideas using your mouse and save them as a JPG. You could incorporate this into drawing plans and designs for your instructable! It could be a cool feature for everyone, but for pro membership you could have extra things (e.g. rainbow colors, a ruler, paint brush mode). I think this would be a cool addition to the website.
