Using a recycled switch -- Question about voltage

I'm building a simple solder fume extractor using a 12v fan from an old appliance. I will wire in a 12v power supply. The switch I want to use is rated 125v AC at 13 amps. Is there any reason I couldn't use this switch? Or do I need to match the switch's voltage with the fan's?

custom dead-man switch with buzzer

So I am in need of something handheld with a "dead-man switch" that activates a buzzer or some type of alert if you let go. The buzzer would be silent as long as you hold the switch and go off when you release it. Probably build the whole thing into a small piece of PCV so its hand held. I don't know where to start with the "dead-man switch", any suggestions?

Looking for a rotary switch to fix my fan

Greetings.  I'm looking for a 3-way rotary switch to replace the broken one in my Patton fan.  Here are pictures of the original. The company that made the switch does not sell parts retail so I can't do that.  It seems to be a very simple switch.  It's 4 click.  Off, High, Medium, Low. I'd hate to throw this fan out.  The actual motor is in perfect shape.

Fun uses for Reed Switches?

Reed switches are electro-mechanical devices that opens or closes a circuit when a megnetic field is present. They come in normally open and normally closed designs and range from the size of a grain of rice all the way up to several inches long. A relay, another electro-mechanical device, is comprised of a reed switch and an electromagnet trigger built into one housing. Common uses for reed switches (not counting relays which are used in virtually all electronic devices) include the 'pick ups' on bicycle computers and the sensors on window and door alarms. I just ordered a bunch of reed switches and I need your help in coming up with ideas for what to do with them. Post up your ideas for some things that could be made or modified to be triggered by a magnet coming in close proximity to a reed switch. Remember- the magnet does not have to touch the switch, just get close enough that the magnetic force trips the switch. The stranger and sillier your ideas are the better. Note: this is not a contest and there are no prizes. by posting an idea you are giving your consent for anyone who reads it to use your idea. Posts about integrating reed switches into knex firearms will be ignored (no offence, it's just not my cup of tea).

Switching the input to my speakers with a flick of a switch?

I have my 360 hooked up to my computer LCD as I don't have a regular HD TV and this is the next best thing. With my speaker system I normally have my speakers hooked into my PC sound card. What I think is getting a jack extender. Like it has a jack that plugs into my sound card and then I can plug a cord from my speakers into that so I could easily switch between my xbox and PC by just swapping cables. But I would like to make a little switch box so I can keep both of the plugged in and just hit a little switch and change them.

help understanding this switch

Hi im trying to salvage a dvd drive for a project im working on but i dont seem to be able to replicate how the switch works i can get the drive to open an by applying 5v to the + and - and then reversing the polarity to close the dive but the motor will continuously run until the power is disconnected  so i guess this is where the switch comes in, excuse the picture! i assume that when the momentary button is pressed the switch moves to stage 3 and  allows power to the motor until the switch reaches the next stage where power is then cut off, when the momentary button is pressed again the switch moves back to stage 3  which swaps the polarity and again allows power through, and that cycle carries on each time the momentary button is pressed. stage 1 the dvd drive is closed the swith stays in this position stage 2 the dvd drive is open the swith stays in this position stage 3 the dvd drive is either opening or closing the switch moves to this position when the motor is in use  i have a 5v power supply how would  i wire it up to get it to work properly? it seems like it should be easy enough but either im missing something or im just not getting my head around it properly,

Simple wireless on/off switch, possibly using BTE/ANT+ or sth lower tech?

Hi all, I'd like to get your expert opinions on the following: I'm trying to build a simple device. In one circuit, a switch closes. This sends a signal wirelessly to a nearby circuit (~1m away), which receives the signal and turns on an LED. When the first circuit breaks, the LED turns off. Sounds simple. The circuit containing the switch has to be very small/lightweight, and power conservative. I'd like to have more than one of these switches around and by closing either switch the LED would turn on. But these switches must be paired with the LED, so that another separate LED nearby will not be turned on. This led me to think about using something like Bluetooth Low Energy or ANT+, because the modules are really small and can be powered by a button cell battery for months. I can't use IR because there's no direct line of sight. Are there any alternatives besides these two options? If I choose BTE, what do I need apart from the module to get the circuit working? I mean stuff like PC-module connection, battery connection or IC or other stuff like controllers? Thanks :)

An illuminated light switch that will work on 120/240V AC.

I have a fluorescent light fixture that my dad gave me, it was about 9 feet, so I cut it in half and re-did the wiring so it would fit on my workbench. It uses a plug to turn on and off. I know the wall switches they sell at home depot are rated for 120/240v but they are cheesy looking and hard to locate in the middle of the night in my garage. When I come home from work on my motorcycle, I need an immediate source of light. Is it possible to use an illuminated switch, say from, Oreilly's or Advanced Auto parts and add some form of surge protection so it won't blow or pop a breaker? I want to use the same concept as a surge protector, it uses an illuminated switch, but only cause its components are protected by the surge. Is it possible to make my own involving soldering components on PCB?

Ignition switch for an electric bike in the UK.

Hi folks. Does anyone in the UK know a dealer who could supply an ignition switch/battery lock for a Thompson Classic electric bike? I've had a look around the interweb & ebay & cannot find a suitable replacement switch anywhere, there are plenty that would fit but none of them seem to be the correct one as they only have one "On" position the one I need has two, one is for pedal assisted & the second for fully powered. The switch also locks the battery box onto the frame it looks similar to the larger of these two on ebay. I have called the importers & their quote for a replacement carries an outrageous price compared to the third party ones I have seen at over eight times the price plus postage & although I expect to pay a bit more for a slightly more complex part I certainly don't expect it to be THAT MUCH more. I'm sure there must be other bikes that use similar switches but haven't as yet been able to find a dealer who can help. Any suggestions would be gratefully received. Thanks in advance for your help. N.G.

Simple time switch "Help"

I live in a narrow road with high walls each side.   Getting my car out of the gateway is therefore a problem because I have to stick the bonnet out into the road before I can see that it is clear.  So I bought a 12 volt LED flashing beacon to put on the top of the wall at my gate.   Now I need a device which will run the beacon for about 20/30 seconds after I push a button, giving me time to get into my car and edge out.  I could, of course, stop and block the road while I go back and turn the beacon off but a time switch would be a help to good relations with other drivers.   Can anyone please tell me of a suitable switch or circuit?   John C

7.1 DIY audio switch, please help

Dear Instructables community,I stumbled on to this site while looking for a DIY solution to a problem where no commercial alternative seems available. The problem? I need a dual input/output switch for my 7.1 audio system.What I found on this site was:'m "OK" with a soldering iron, but I've never really built anything before, and I'm not familiar with some of the terminology. Really, the only things I have done in the past have been soldering plugs on the ends of wires and re-soldering loose connections. Even so, I'd like to build something similar but for 7.1 with dual inputs and outputs.I'm hoping you can help me make the right choices building this.My original plan was going to be just like the 5.1 version with a few most switches, but instead of the input 3.5mm jack as the source for the switch, I would just connect another switch and then connect it to two 3.5mm jacks.(See attached image)Will this work without taking a hit in audio quality?Is there an easier or more efficient way of doing this?Here's the hardware I selected initially:Switches:;=10001&catalogId;=10001&productId;=76260&3.5mm jacks: don't understand most of the terminology on these parts, but they look like they should work.Please let me know what you think, I'm open to advice.Thanks!

Hacking a 1-sec accurate timer

Hey all, For my digital SLR camera, I've hacked together a cable relase using a three-way switch. This works a treat, and now it's time to graduate to full automation to help with night time navigation. For this I need to build a timer that keeps a switch in the 'on' position for a certain number of seconds. The timer needs to be accurate to the nearest second, so nothing fancy. Ideally it would be a number pad I can type into the number of seconds. So any ideas? I'm putting together a short instructable to make the cable release. Cheers, Pierre

Sound activated switch

Hey, my friend is a drummer and he's trying to install LEDs inside each one of his toms that would come on when he hits the tom. He doesn't know anything about electronics so he asked me and I don't know much either so I'm asking all you awesome people at Instructables. What I want is a simple sircuit that will not cost me above £5 that will allow me to do what I mentioned above. I have a soldering iron and can solder stuff easily so I just need the parts and (preferably a stripboard) layout. He will be using a max of 16 red 2v 20mA LEDs in each tom so the circuit will have to be able to supply either approx. 32v 20mA if in series, or 2v 320mA if in pararell. So, any recommendations?

Wiring help

Hi guys I am need of some advice and help if possible, I will try and explain as clear as I can. I have a lockup which I have modified to use locking bolts on a motor and I have a swipe card reader and pcb which when swiped it fires the output to power the motor (6v) which works perfect for 6 seconds of the locking bolts going in and out. I am looking for a way so when the locking bolts go to the locked position it hits some kind of limit switch and stops there (which I have done in the past) but then I want to be able to swipe my card to open the bolts and when it gets to he open position it hits another limit switch and stays open until I want to swipe and close the locking bolts. I don't want this to be timed I need this to stop on open and closed position but able to operate when either is pressed, Can this be done in anyway?

Wireless switch , need help on how to make

OK , I am a tattoo artist. I want to make a wireless foot pedal to control my tattoo gun. This is how it works now. It has a foot pedal with a 1/4" phono mono jack that plugs into the power unit. When my foot is pressed down it simply closes the connection and tells the power unit to apply voltage to my gun which has a separate cord coming from the power unit. I would like to make a wireless for this. Maybe a simple remote control toy can give me all the conponets needed. I want it to be small , maybe a 9 volt battery supply. I can have my foot pedal  wire just 10" long going to the a sending unit with an antenna. Then alls it has to do is maybe close a relay that I can wire to a phono jack to just close the swicth to tell the power unit to turn on my tattoo gun. I know this is going to be very simple but for some reason im having trouble thinking of how to do this cheap. Thanks for the input. Jeff

Help for first Arduino project

Greetings all! I just received my Arduino board in the mail on Saturday, and trying to learn how to write code for it. I have figured out how to make a button press trigger a pattern of LED's.  When button1 is pressed, pattern 1 is played.  When button 2 is pressed, it will run pattern 2 (once the first pattern has run twice). I would like to learn how to: 1.  Keep a pattern running continuously (unless the other pattern is initiated). 2.  Press the same button a second time, to turn the pattern off. Here is my code (forgive the sloppiness...I'm new at this): int pinled1 = 1; int pinled2 = 2; int pinled3 = 3; int pinled4 = 4; int button1 = 5; int button2 = 6; int buttonstate1 = 0; int buttonstate2 = 0; void setup() {   pinMode(pinled1, OUTPUT);   pinMode(pinled2, OUTPUT);   pinMode(pinled3, OUTPUT);   pinMode(pinled4, OUTPUT);   pinMode(button1, INPUT);   pinMode(button2, INPUT);   pinMode(8,OUTPUT); } void loop() {   digitalWrite(8,HIGH);   buttonstate1 = digitalRead(button1);   buttonstate2 = digitalRead(button2); if (buttonstate1 == HIGH){ {   buttonstate1 = digitalRead(button1);   buttonstate2 = digitalRead(button2);     digitalWrite(pinled1,HIGH);     digitalWrite(pinled2,HIGH);     delay(500);     digitalWrite(pinled1,LOW);     digitalWrite(pinled2,LOW);     digitalWrite(pinled3,HIGH);     digitalWrite(pinled4,HIGH);     delay(500);     digitalWrite(pinled3,LOW);     digitalWrite(pinled4,LOW);     }} else if (buttonstate2 == HIGH){ {   buttonstate1 = digitalRead(button1);   buttonstate2 = digitalRead(button2);     digitalWrite(pinled2,LOW);     digitalWrite(pinled1,HIGH);     delay(500);     digitalWrite(pinled1,LOW);     digitalWrite(pinled2,HIGH);     delay(500);     digitalWrite(pinled2,LOW);     digitalWrite(pinled3,HIGH);     delay(500);     digitalWrite(pinled3,LOW);     digitalWrite(pinled4,HIGH);     delay(500);     digitalWrite(pinled4,LOW);     digitalWrite(pinled3,HIGH);     delay(500);     digitalWrite(pinled3,LOW);     digitalWrite(pinled2,HIGH);     delay(500);     digitalWrite(pinled2,LOW); }} {   buttonstate1 = digitalRead(button1);   buttonstate2 = digitalRead(button2); }} Thank you to anyone who can pass on some knowledge!
