LIke a motion activated flood light, I want to activate a light/lamp by switch closure and have the light/lamp remain lit when the switch is open. I want a timer in line to turn the light/lamp off at some set time (1min, 5min, etc). The circuit must be powered by say a 9v battery, and utilize a LED as the light. I would like to use a fabric switch where temporary contact completes the circuit powering the light.

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

I'm interested in making vinyl wall decals myself for my apt. I saw one instructable to cut the design on contact paper and stick it on the wall. But what if I have my own design (image) on my computer and wanted to print that on the contact paper. Can I do it using my inkjet printer or do I need any other special paper? Basically I wanted to print my design on any vinyl paper and transfer that onto the wall. Thank you...

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!

As reported in Science Magazine online today: A group of citizen scientists has commandeered a NASA spacecraft that was launched in 1978 and had gone unused since 1997. Today the group made first contact with the International Sun-Earth Explorer-3 (ISEE-3) when the spacecraft acknowledged receiving a signal from the Arecibo radio telescope in Puerto Rico, says Keith Cowing, co-director of the ISEE-3 Reboot Project, a group of about 20 volunteer space buffs. “We knew we could do this—it’s a vindication,” he says. “It’s sort of like reaching back in time to grab something that otherwise would have been lost.” Making contact isn't all the group plans to do. Next month, they plan to instigate a burn with the remaining fuel and move the spacecraft into a new orbit. The group is doing this with no direct funding from NASA: they raised nearly $160k needed for for software development, access to NASA archives, and Arecibo and other telescope time via the RocketHub crowdfunding site.

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.

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.

Can anyone offer ideas as to how I could make a good electrical connection to those black pads on the LCD screen? I don't even know what they are made of (...graphite...?).

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?

Hi! I have a project that needs to sense whether water is flowing through a pipe. I bought a water flow sensor on Amazon (https://www.amazon.com/gp/product/B01LVWHJP0/) thinking I could use it as a basic switch, however, it's got a hall effect sensor and I don't understand how to deal with the voltage output. Measuring from the pulse signal to ground, the sensor swaps the polarity each time it's triggered: With water running, I see a positive voltage. Turn the water off and back on, voltage goes negative. My control system can't deal with this. What I need is a simple circuit to turn the sensor's pulse output into a contact closure. Can anyone help? Thank you!

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!

My idea is to attach a contact microphone to the wrist to listen to finger-taps and determine which fingers produce the taps. Assumptions: - The tap sound propagates along the bones like in tubes, - Each finger produces a characteristic sound signal. - Pattern recognition of sound signals identifies the sound and the finger that produces it. Any help? Thanks

Okay, so I've been working on a prop for a Team Fortress 2 Medic costume, and I've run into a fairly major problem with the wiring of the Medigun. I have everything figured out, except the triggering mechanism for most of the LEDs. In-game, the "trigger" is a pivoting handle, such as one that operates a valve on a firehose. The problem is that I have no idea how to find/install a switch that will activate when the lever (indicated below) is pushed forward. I'm still trying to decide how to install the switch, but as long as the switch is active through a given angle, the installation shouldn't be too difficult to negotiate. Another problem is finding appropriate switches with low actuation forces, but that's an entirely different issue. So, where could I buy that sort of switch, or barring that, how can I make one that will hold up decently well? Thanks in advance!

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

Hello instructacles, I'm trying to build a simple contact-based set of sensors embedded in card board, paper or thin plastic sheets. I want to make a simple game for my kids that could detect/react to the presence/absence of some random items positionned on such a board? (empty glass bottle of coke, cereal box, shampoo bootle, you name it) Ideally i would use something like those books for kids where they have metallic threads "printed" on think plastic sheets and when you press them, it triggers a music. But i dont know how to print metal basically. don't really know how to get started. I was thinking of sewing conductive thread but i'm not really sure it would work. I have seen many attempts with aluminium foil (ex: https://www.instructables.com/id/Interactive-Art-With-Scratch-and-Makey-Makey/) but those are based on the fact that a human finger touches them (basically it uses the conductivity of skin), whereas in my game i was to use the weight of random objects from the house (in the 50g to 500g range typically) Any idea how i should get started ? thanks fourchu

I'm looking for a specific type of switch... I believe that it must exist, but I have never seen it... I need a rotary switch, where each clockwise "click" (partial turn) makes one circuit momentarily, and each counter-clockwise turn makes a different momentary conection... example with two light bulbs ( L1 and L2 ) connected to each direction of travel, respectively: If you rotate the knob one "click" (say 15 degrees) clockwise, L1 flashes for a moment, as the knob is in motion. if you continue clockwise, L1 will flash at each "click". If you rotate the knob one "click" counter-clockwise, L2 flashes for a moment. if you continue counter-clockwise, L2 will flash at each "click". There is no center-point, so any clockwise travel corresponds to L1, and any counter-clockwise travel corresponds to L2. does anyone know where I could get a couple of these??
