DIY BlackLight Contacts?

I know you can use Tonic water to make Blacklight reactive ice, But can you use this same method on soft contacts? I have no idea on weather tonic water is bad for your eyes, even less whether soft contacts are saluble enough for this trick to work. I figure a mix of 2/3 contact solution, to 1/3 tonic water soaked overnight might be enough to give your contacts a soft glow under blacklight. But I just dont know!Anyone willing to try this with some "overused" contacts?Glow Ice, How-to

push button contacts fail

Hi, i disassembled my full-automated coffeemachine as the push buttons for programs failed. The buttons are a line of rubber and the contacts on the platine are toothed while each rubber contact got tiny plates that bridge the contacts on the platine. I guess that the contact plates lack of conductivity - any suggestions what i can do to improve the conductivity? I thought bout buying contact foil and glue it over the rubber contacts, but i don't know, if this is the best solution.

My eyes are dim, I cannot see...

You may not know, but I wear contacts. They're monthly disposables - I can leave them in 24/7 for most of a month, as long as I go without for a coupld of day in between. Unfortunately, I seem to have lost my spectacles. Since last I wore them, I have been to Cornwall (other side of the country) and on cub camp (in a field). I fear my spectacles are lost somewhere between. Being massively short-sighted, I am consequently having trouble seeing things. I have "Ctrl+ed", but I still have my nose just a hand-span from the screen and key-board. So, if I accidentally post gibberish tonight, and the next night or two, blame it on the mole-eyes. UPDATE: I have a headache, g'night all.

What is this component called?

I don't suppose anyone would happen to know the technical name for this type of switch? I'll be using one in an Instructable I am currently making, but am unable to find this kind of switches name (if indeed it does meet the specifications of a 'switch'). Thank you.

Making a plate which detects contact with metal

Hello, I'm trying to make a 6" x 6" plate which can detect when a needle comes into contact with it.  The plate can be made out of whatever ( preferably an easy to obtain material like a metal sheet) and have any electrical components necessary attached to it but the needle can't have any attached wires etc.  Any thoughts?

PVC-Free contact paper alternative?

I recently learned about Con-Tact brand chalkboard contact paper, which I think it really cool! You can cover a surface in it and write with chalk. I thought it would be cool to use a laser cutter to cut the paper into shapes, letters, etc. and put it on the walls. Alas, after contacting the manufacturer, it turns out to be made of PVC (vinyl). Laser cutting PVC produces chlorine gas, which besides being toxic, is also highly corrosive and bad for the laser cutter. Anyone know of an alternative that's not made of vinyl or PVC? It doesn't need to be big like contact paper, and it doesn't need to be chalkboard-like either (for chalkboard stuff there's paint), but I'm most interested in some kind of material I can cut into shapes and stick onto walls and other things. Thanks for any ideas!

Help with a momentary contact switch

Hi everyone. I'm currently working on a new Instructable, and I've hit a small wall. What I'm looking for is a momentary contact switch that closes for a second, then opens again on its own independently of the actuator -- and I can't quite figure out how to do it. To clarify, here's the operation: You lift the receiver (or handset, or whatever you like to call it) on an old telephone, and the buttons -- normally held down by the receiver -- lift up to create the contact so the telephone knows you've answered and the call connects. Well, this phone isn't going to be connected to the telephone network any more, but what I want is for a contact to be closed momentarily when you lift the receiver, and then opens again automatically on its own even if you haven't put the receiver back down. I also want the same contact to be made when you eventually do put the receiver back down -- so you replace the receiver, a contact is made momentarily, and then opens again on its own, even though the receiver buttons remain down. I hope that makes sense, and that someone has a bit of advice on how to achieve this. Thanks in advance! EDIT: Been continuing my research, and found the following: http://www.simprojects.nl/toggle_to_momentary.htm Can anyone confirm if this will achieve what I'm looking for? Thanks again.

Support contact problems

Hi, Is anyone else experiencing problems contacting the Instructables support team via email? I have tried to email them via different channels three times now but it comes back as non-existent email address.... ironically the reason I'm trying to email support in the first place is because despite changing my contact to a new email address in my personal settings, emails are still being sent to my old email address. If anyone knows how to get through to support or if they are having the same issue maybe we can join forces to resolve it..? Cheers!

How to make sterile saline for contact lens storage

It would be amazing to learn how to make sterile saline solution for simple contact lens solution. Most commercially available contact lens solutions have harsh detergents (granted, to keep bacteria at bay), and they are expensive and irritating. I've been using plain sterile saline for years without issue but it's just salt and water - can't somebody tell us how to make it for free?NOTE: Nevermind. I just saw this crazy letter. http://www.craig.copperleife.com/health/saline.htm. I will stick with store-bought.

Why can't I contact you people??????

This is madness!, You send emails around with all the new stuff, great, I like that! BUT: ALL THE LINKS FROM EDITORS CHOICE DON'T WORK!!! If you had a normal email addres I would have been able to contact you some time ago, but you don't seem to think this is important! The links used to work, now they don't anymore, my time is to valuable to go through the whole of your site to find what I'm looking for, so soon I will unsubscribe. The fact I went through all the trouble to contact you, although you try to avoid that, means I want to stay with you. Please fix this, or won't be bothered anymore. Best regards, D.R. Reijgwart

Simple Circuit Question LED light/ Metal contact

I have two pieces of metal, pretty heavy stuff, probably stainless steel, and was toying of the idea of being able to wire them up so that if they were touched together it would light an LED. See attached illustration for a general idea of what I am talking about. I am not sure if this is even possible. I think I may need to have some pad-style contacts wired to the very edges, so I'm limiting the surface area that is making contact... otherwise it seems like it may need an awful lot of voltage/current to get through all that metal, probably drain batteries fast too...? Another thought is if the metal were left like it is in the diagram, separated, and if you could bridge the gap with a finger and have it light, that would also be very cool.. just don't know if it's possible. Thoughts?

Home to get layers of old plastic contact paper off of sheet metal?

Hi! I bought this old sink at a salvage yard.  It has a sheet metal bottom with some drawers and cabinets. They are lined on the inside with this plastic contact paper that's been stuck on for 50 years. I have tried getting it off by applying extreme elbow grease and a metal paint scraper, after soaking the surfaces for a while in this stuff: http://www.wmbarr.com/product.aspx?catid=36&prodid;=155 ("Cirtistrip Low V.O.C. Adhesive Remover") but its still pretty much not coming off. Anyone have a better idea about how to get this stuff off? A greener, not-so-toxic method would be great... but I'm not sure if there is such a thing? (FWIW: The sheet metal is not bare, it has a white paint/enamel-type coating.  Which is pretty scratched up in places.  I intend to sand & repaint it, once I get the contact pager off.)

Simple CNC

Does anyone have any information about the three programs, Simple CNC, Simple Art and Simple Engrave. I went to the website, and there is an order page, but the contacts and support buttons are dead.  There is no way to get in contact with them. Before I checked this I actually ordered Simple Engrave and was told I would receive an invitation to the CNC forum.  But I have not received the invitation and have no way to contact.  And of course, no program since it has to be downloaded from the forum. Should I just start a grievance with Paypal?

How do watch glow backlights work???

I recently took apart a digital watch that had a green glow type of backlight. Looks like there was a backplate, behind the LCD screen, with what seems two contacts on opposite ends. No matter how I hook up these contacts to a 1.5V battery, I can't get it to glow. Any ideas????

Convert sound signal to dry contact signal?

This might be a bit of a strange question, so will try and word it so someone can follow along. I posted a thread previous about getting my doorbell chime to work with SmartThings.  What I now have is a sensor with external input.  The keep it simple, there inputs are GRND and IN.  When the 2 inputs are joined, the device reads CLOSED and when they are apart, the device reads OPEN...perfect. I've been trying to find a point on my Chimes circuit board that would create a dry contact between 2 points to trigger the sensor, but I'm not having a great deal of joy. There are however, 2 wires running from the board to a speaker in the unit.  Is there anyway I can get convert the signal to the speakers into a signal which would connect the 2 wires? I know a speaker is an electromagnet that responds to electric signals, but wasn't sure if there was something preventing the contact being made between the 2 sensor wires

If I'm viewing an instructable and click Add Comment, the login box pops up, I enter valid login details, and it just goes back to the instructable page without my being logged in.  If I try to do the same again, the cycle keeps repeating.

Smoke bombs that explode on contact - version II

Smoke bombs that explode on contactmy idea is as followshave an outer layerinside that you have small glass capsules which will break and ignite the negative-Xthen another very very thin shellthen the inner core of a regular sugar & potassium nitrate smoke bombthe way it works is the bomb will hit the ground causing the the glass around the water to breake causing the negative-X to react then that ignites the smoke bomb which will make smoke billow out a designated holeps. if you want to know how to make these things go tohttp://www.unitednuclear.com/negx.htm for Negative-Xhttps://www.instructables.com/id/E6F4H9Z605EP2867LO/?ALLSTEPSfor the smoke bomb

The body...and electricity

So a few years back, my teacher had this toy chick, that had two contacts on the bottom. When you touched both, it chirped. Whn you touched one, and you touched a friend who touched the other, it chirped. So if electricity can run through you like that, why cant the same thing work with a battery and something that takes that battery? (leave the +side in, touching the - side, and then touching the contact for the - side)

How can i be of help? Barry ********** Hi Barry, Thanks for getting back to me. I was wondering if you’re still active on Instructables? I’m working with a retailer where we’re looking to link up with an Instructable to provide them with kit to create their next maker project. Would this be of interest at all? Best, Kev It seems a bit suspect to me (but i could just be being paranoid) the site looks legit enough and google brings up nothing untoward about them. Thoughts?

Help with Arduino programming for LED display

What I want to do is keep score with my coin soccer game. I will have 2 metal contacts in the goals that when a coin goes through it will break contact and send a signal to the Arduino having the contacts allways HIGH and then when its LOW, it changes an 7 segment LED. I am very new to programming and the C language. I think I can write the whole IF and ELSE statements but I don't know how to make the LED display change. I need the LED display to change after getting the signal from my Arduino by going up one number. It is a single 7 segment display. Can someone help me with the code for that? Thanks in advance.
