Who is in Denial of their Color Blindness?

So apparently, I was never actually tested for this as child.... It's only recently that I've discovered this too o.0 Test for Color BlindnessPersonally, I have issues with reds. Show me two shades of red, right next to each other... And I won't be able to tell the difference.... On the "5" plate closer to the bottom of the page, I first saw an "S" :/If you didn't read it --- if you're a male, you're more likely to be color blind than your female counterpart....

new blinds flapping in wind

I purchased a horizontal blind for my (single) sliding glass door (SGD) which was a mistake. I should've bought a vertical blind since whenever I open the SGD a bit the wind catches the blind like a sail and it makes a racket when it smacks against the frame. Obviously a vertical blind could've been opened a bit more than the SGD so the wind would not catch it. Any thoughts on how to remedy my problem would be appreciated! Dan

Window Blinds

I have an airconditioner unit (old style) that sticks out about 5 inches (12cm.) further than the frame. Into the kitchen. I currently have curtains but want to have blinds of some kind for a more modern look. How can I have blinds if the place for attachment is not the same across the window. Any help will be usefull, I'm stuck.

Motorized/electric vertical blinds?

I have some vertical blinds in my living room that are manually driven via a cord to tilt the blinds and another cord to open or close the blinds. I wonder is there a conversion kit to open/close and tilt them electronically via a remote control? I have found some kits from hundreds of dollars to thousands, but know I could find one or build one for way less. Any thoughts or ideas?

Solar Power Blinds

Im just posting this as a thought,cause I thought it would be cool if you had some blinds on say the south side of your house and you glue or attached strips of solar panels to the out side facing panles and you would turn them to the sun I know its possible and you could even lift them up

Any ways to make a motorized Blind?

Any ways to make a motorized Blind? Saw someone on instructable made one, but without instructions. I read somewhere, someone mentioned to go SOMFY SYSTEMS INC and read about motor and cord take-up system that fits into the existing blind headrail. But SOMFY SYSTEMS INC mentioned the specs and not on how to do it. Now i am kind of lost. As a beginner, i am only at this stage. This is what i found.   www.distel.co.uk/DC_MOT_CON1.htm  I need to know what kind of DC motors with what voltage and power, can roll up a blind. Wonder will a 12V DC motor with 30rpm do the trick? Thanks!!!

Automatic Blind Opener Advice

Hi, I am thinking of putting together something that will able to automatically open and close my blinds as the darkness outside dictates. Ideally, I am hoping to attach the opening/closing pole to a DC Motor, which would be controlled by a light sensor. I was also toying with the idea of powering the system with a rechargeable 9V battery that could be topped up with a small solar panel attached to the window. Is this idea doable and, if so, any advice on parts and putting it together would be very much appreciated.

Faux Window

I'm looking for ideas to make a fake window for my cubicle at work. Ideally, it would be lightweight and provide something other than the flourescent lights above. I really like the look of Bright Blinds (see attached photo). I'm thinking a DIY version of that with maybe a poster with a view behind the blinds? I'd love some input on how to go about this project! Thanks!

Whippy Light: For Greens Who Like to Blind Themselves

This clever light fixture takes the shape of the CFL and manages to incorporate it very well. Of course, the problem is that this only looks good when it's not lit. Turning ti on to, say, light the room will quickly turn this from a conversation piece into a bright nuisance.Nice idea, tho. Link

DIY data transver alarm for a blind friend.

Hello! A good friend of me, who happens to be blind, posted an interesting question on facebook earlyer today, and it got me thinking. He wondered if it would be possible to get alarm feedback from a usb key when a file is done saving. So I was thinking, could I somehow do something with a transistor or a relay on a usb cable, to sound an alarm for 1.5 seconds when the voltage turns to absolute zer0. I know how to solder and i did projects before, but never something like this, with this kind of tech. so tips and feedback could be welcome.

DIY Blackout Blinds?

Does anyone have any ideas on how to create a super cheap, super easy way to create some blackout shades for my bedroom without buying expensive custom-sized blackout blinds? I fact, I already have custom-sized blackout blinds -- except they're roller blinds, and when they're deployed, although their size is exactly the same as my windows (about 70" wide by 20" tall) when they're rolled down, and the sun is shining on them, the light literally blasts through on all sides, rendering them almost useless. What  I need is a light barrier that makes the room pitch dark even if the sun is blasting directly on the windows. I looked at this site: http://www.blackoutez.com -- but after ordering, and even if they do ship to Canada, it's liable to be prohibitively expensive. What I need is something cheap, easily mountable, easily unmountable and able to be stowed in a closet every day, then brought out every night for the next day. I thought of using those dollar store poster boards, maybe taped together with duct tape. Black ones would probably do a good job of blocking the light and they're pretty big -- maybe 48" x 36" -- but there is still the problem of how to attach them to the tops of the windows. So again, here are the criteria: Cheap, maybe less than $50 all together Block ALL light completely Easily mounted, easily unmounted Able to be stowed quickly and easily Durable, able to be used every day for months Able to recite the Gettysburg Address with no cue cards (Okay, I'm willing to forego the last one!) Turn your inner geniuses loose! Thanks in advance Nickster

Would shades, or sunglasses protect you from flashbangs?

Let's say you are in a situation where every second counts. Do wearing shades or sunglasses protect your eyes from temporary blindness as a result of a military grade flashbang? If not, what are some ways to protect yourself from the bright, instant flash of a flashbang? What are some ways I could imitate the blinding flash of a flash bang, without having to use actual flash bangs for an experiment? I'd appreciate your ideas.

Help- My Printer is BLIND!

So here is the story- my grandma moved out of our house, and I got an older Windows 2000 computer. I also got a working (at the time) printer (jetprinter...HP...I think) and hooked it up in my room about a month later. The ink was low, so we spent ~30 dollars on new cartriges. So, even then, I hooked it up... hit print, and buzz click whirr...just like it should...and bloop: load paper is displayed on the screen. But wait...it had paper..a bunch! So I took it out, restartyed the computer, turned off (and then on) the printer seperately, and tried to print agian. No worky. Supposedly the printer is still out of paper, even though it is sitting right there! Is it blind?!?!?!Any help would be appreciated. It is a good printer (or was), and the ink in it alone is new and worth $30!

Proximity Sensor 1' - 25'; Bat Ears for a Blind Woman

First of all, I'm a noob in electronics, so please explain your jargon as you would to a 3 year old. I am smart & learn quickly. So, I really want to make my blind 80 year-old grandmother a pair of bat ears. I bought her one of those sonic distance measureres from home-depot because of the barely audible tic they send out to bounce off wall/etc and record the time it takes the signal to return. You can hear the tic, and with your eyes closed.. you can kinda tell how far things are away from you just by listening. She loves it, and it just barely.. kinda works. What I"m shooting for is a single over-ear headphone (xbox-live communicator style) with some type of proximity sensor attached, sending a constant signal to the headphone... low for long distances, gradually higher for gradually closer distances. Any reasonable suggestions would be greatly appreciated.

Tarantula Defends Territory Against Owner; Owner Almost Blinded

Got a pet tarantula? Better protect your eyes ----------------------- WASHINGTON Fri Jan 1, 2010 10:53am EST WASHINGTON (Reuters) - Here's some advice stemming from the unusual case of a man who had spider hairs stuck in his cornea: Be sure to cover your eyes when hanging around with your pet tarantula. Ophthalmologists at St. James's University Hospital in Leeds, England, used high magnification lenses to find out what made the man's eye red, watery and light-sensitive, according to a study reported in the British medical journal The Lancet on Thursday. They discovered hair-like projections stuck in the man's cornea. It was a light bulb moment for the patient, who remembered that three weeks earlier he had been cleaning a stubborn stain on the glass tank of his pet, a Chilean Rose tarantula. "He sensed movement in the terrarium. He turned his head and found that the tarantula, which was in close proximity, had released 'a mist of hairs' which hit his eyes and face," the doctors wrote. They said the man's condition was rare. The authors noted that the Chilean Rose tarantula releases the barbed hair on the back of its body to defend against predators. "We suggest that tarantula keepers be advised to routinely wear eye protection when handling these animals," the doctors said.   ----------------------- Ok, so he might not have been blinded, but in theory, he could have developed a horrible infection that could have blinded him.  I'm listing tarantulas next to porcupines as pets to not own.

Safety or lack thereof

Hi, Does Instructibles have a duty of care with regard to the safety on the ibles that are presented on the site? In the past, people would put "please don't try this at home, please be instructed on soldering/HV/lasers/...." now I am seeing some 'ibles that are carelessly dangerous. Some examples are: - connecting a microwave magnetron to a high gain waveguide antenna output - circuits and places to purchase lasers that are not eye-safe, even likely to blind and burn (1W diode lasers) - HV circuits that have no protection / current limiting, creepage and clearance considerations etc. Maybe I am a grumpy old man, but it does worry me! I would hate to see kids blinded just because they read an ible without understanding the dangers, build something up and become blinded.  Would you like it if that was your kid and they saw it on ibles? For the budding inventors out there, to get the product to market they will have to consider safety in the designs.  Why not start now as part of the product concept? Not trying to be a scaremonger, just trying to understand where people are coming from and provide some suggestions on how to improve things: - provide check boxes or an icon that people can tick (eg skull and crossbones for chemicals, laser safety icon etc.) - provide standard warnings - refuse to publish or ask for rework of 'ibles that are recklessly dangerous - sponsorship for a 'safety first' ible competition? - ..... Is this something that 'ibles would be interested in? Regards Steve

Or maybe this is already implemented and I'm horribly blind!  hehe Anyway, thanks for listening :)

Tech Deck Skate Park (WIP)

I've recently started to build a tech deck skate park. The base is mdf (solid stuff, very heavy), and all the features will be made from wood with metal coping. The base is 36"x16" to fit on my desk. You can track my progress here: chrismccann.wordpress.com Let me know what you think, what you might change, and what you like/don't like. Also if you need any closeups of anything, I've got it saved in CAD and can post any screenshots you guys want. Also, here are a few questions I have for you guys: -The flat rails were easy because they were handles, but how could I make the rail on the stair set? -How should I cut the profiles (out of 1/2" plywood) that will be the shape of the quarter pipe? I need to accurately cut that radius, but I only have a crappy band saw, 1" belt sander, drill press, dremel, and various hand tools.

The Dangers of Disney

I was trying to find out who was currently leading the US presidential polls, when I got distracted by an item on Freedom of Information. That led me to this article. Isn't the internet wonderful?Inhaling helium to produce an amusing squeaky voice (a favourite game for children in the United States and Europe) may not be the innocuous party trick it seems, according to emergency medicine physicians at the Wesley Center for Hyperbaric Medicine in Brisbane, Australia (Annals of Emergency Medicine 2000;35:300-3).Simon Mitchell and colleagues report the case of a previously healthy 27 year old man who inhaled helium and subsequently developed a stroke with transient blindness and radio-graphic evidence of cortical infarction. However, the man had inhaled the gas direct from a pressurised canister, whereas most children who perform the trick - to imitate the voice of Mickey Mouse - inhale the gas from helium filled balloons.The patient developed rigidity and lost consciousness within moments of inhaling the helium. On arrival at the emergency room 15 minutes later, he regained consciousness but was found to have complete visual loss and evidence of cortical infarction.PubMed ArticleI still haven't found out who's leading, though...

I know Kipkay did it first, but this is still awesomely awesomeful :-)  I saw this on MAKE's blog; the original posting is from Jay at Hack'N'Mod.  Using a 12x Blu-ray laser (405nm) running at 465 mW, this has enough power to blind you without eye protection.  It's got a front focus with a properly styled ST:TOS nosecone, and two different selectable sound effects.  Jay's writeup is a complete tutorial for building your own.

What would you do with a Deuterium Lamp?

I was going through a box of junk a University Lab wanted to get rid of and I pulled out a Deuterium Lamp. This small thing produces a steady blue-green light as powerful as a camera flash, but most of the light these things create is in the UV Spectrum. I Feel like I must make something with this. My First thought is to block the UV so I don't blind anyone and turn it into a bike light, but I already have an epic 300 LED bike light. Can anyone think of a good application for a powerful source of UV Radiation?

Semi-adhesive materials

Hi, I'm looking for some suggestions of what I'll call (out of ignorance) "semi-adhesive materials". I am looking for a large sheet that can be folded, or preferably tightly rolled (think a window blind) and a variety of shapes that can be stuck on and repositioned. I've had a look at display felt for use with hook and loop stickers. The felt is quite thick and expensive. I'm just wondering if anyone else has experimented with this kind of project. Flexible magnetic material, or some kind of static attraction or something? Cheaper the better really, but durability is a big concern too. Any pointers in directions to look would be greatly appreciated.
