Rewire the laptop power button.

Hi, I have a desk and I've put  shelf on it that is 4 inches high from desk. On this shelf lie two 23 inch monitors. Below the shelf, tucked away, is my laptop (with the lid closed). The problem is that I need to be able to turn the laptop on without opening the lid. (The power button is right above the keyboard). My motherboard does not support Wake on LAN but it does support USB Wake. This is a bit useless to me, however, because it doesn't allow me to fully shut down the computer, but rather put in stand-by. So i wanted to know if there is a way to attach an external button (maybe a push switch) that can power the laptop? If so, can anybody help me out how to do it? I'd assume it would be in parallel to the regular switch.  I have an Dell Inspiron 1521 (which I think is a fail to being with :P ) Thanks! AK

Wiring Staples Button to Xbox 360 power button

I have an old white xbox with a broken disc drive which if I fix I will give to one of my friends. The plan though was that before giving it to him I'd spray paint it red and stencil in the yellow the hammer and sickle onto the top. My second idea was then to use the steps found in this guide: https://www.instructables.com/edit/new?type=forumTopic&categoryGroup=forums&category=burning_questions to record the Russian national anthem onto the board, and then wire it to the power button so that it would play whenever he turns it on. Do any of you have an idea on how to go about wiring this to the xbox's power button?

Arcade Single button power everything?

So here's my issue, I have a really nice button for powering on my MAME arcade. The button has 4 wires 2 for LED and 2 for the switch. I currently have that button wired to a USB cable and the soft start of the computer so that when I press the momentary switch it turns the computer on and then it also lights up the power LED of the button. I have the -ve of the switch and the LED wired together so i have 3 wires vs. 4, and then i have that wired to the -ve of the usb. The other 2 wires are +ve of the usb and to the +ve of the cpu power switch. Now I was wondering if anyone has an idea of how to wire up the Monitor to power on. It has a soft momentary switch for turning it on. I attached a headphone cable to the terminals of the button so I can easily unplug it when needed. I tried wiring this in parallel to the power button but that causes weird issues with the computer power. SO my question is, is there a solution to get this to work?

Is it possible to modify a soft-power button?

I'm not sure if this is the correct place to post this (apologies if its not).... I have a small stereo receiver (Lepai S-60) that I use to power speakers in my kitchen and it works well, but the stereo requires that I press the power button on it or the remote every time I want to turn it on.  I was hoping to hook it up to a WeMo switch so that I could turn it on/off via Google Home, but the fact that its a soft power button means that even if the switch turns on or off, the radio doesn't remember what state it was in last. Is there a way to modify the circuit board so that the receiver is always on and thus, I could control it via the WeMo switch? Thanks in advance, Tim

Arduino Powered Motor Controlled by Push Button

I am very new to Arduino, but have a project in mind that I would love help with. On Friday I will have the Arduino Mega 2560 Rev3 and many extra parts like servos, motors, etc. I have also read through Intro to Arduino V2 and Arduino cookbook, so I'm trying to learn but I'd appreciate any help I could get with this project. I would like to control a stepper motor with a push button to lower what will basically be a drawbridge. I will need the motor to stop at a certain point and then be able to push the same button or another to raise the bridge. I may also want to incorporate a Scrolling LED on the box housing the button(s). I'm still a noob but the code looks like something I would be able to work out (but I'll take any and all advice), I'm going to need a lot of help with designing the circuit and being sure I know how to connect an outside power source so I do not short the board in anyway. Any and all help would be greatly appreciated and I will gladly list you as a source when this project is completed. Thanks! -Will

Carbon Button Lamp

The Nikola Tesla group forum is asking for new projects, so I'm posting this as a suggestion. I would love to build it myself, but I lack the tools and money. This is my first contribution to Instructables, so please comment constructively. Nikola Tesla invented the Carbon Button lamp as a kind of incandescent light, because Thomas Edison banned him from using his incandescent filament bulbs. Nikola later discovered that versions of it could also be used in wireless, trans-Atlantic telegraphy, and to investigate what we now call x rays. In fact, he even used the lamp (or something similar to it) to take x-ray photographs, 8 years before Wilhelm Rotgen discovered them.For this reason, I must warn you: this device may possibly generate x rays. I am not responsible for any harm of any kind that may or may not result from re-creating this interesting device. There are phosphors that you can buy that will absorb x rays and re-emit them as visible light. I recommend that you coat the bulb with it until you know for sure that the x rays aren't strong enough to hurt you, or if makes x rays at all. Mixing it with a phosphor made for uv light wouldn't hurt either. Theory of Operation:The bulb is powered by a Tesla Coil, or other source of high voltage, high frequency current, such as a driver for a plasma globe (actually, the modern plasma globe is descended from this kind of technology!)When the power is turned on, electricity bombards the carbon button. Because carbon isn't the best conductor, this causes the button to heat and release electrons into the bulb's vacuum (the technical name for this is "thermionic emission," or the "Edison effect") . These electrons, in turn, excite the remaining air molecules and cause them to create visible light. This is strikingly similar to how fluorescent lamps work!Supposedly, the bulb should shine 10 times brighter than an incandescent bulb.(Note that the excitation of the air molecules, not the incandescence of the button, is actually the main source of light from the bulb.)If anyone decides to build it, please post an instructable showing the steps and finished product. I suggest you get started by reading the patent, number 514,170. You may also want to read part of Tesla's lecture, "Experiments with Alternate Currents of High Potential and High Frequency."To anyone who will attempt this, I wish you good luck!

When powered off, it will trigger the switch again. I'm thinking of using this for my home made coin operated PC. There are various options for the coin operated PCs from shutting off the monitor or keyboard & mouse to software triggered. But I'm thinking of using the stand-by or sleep option of the motherboard. My current setup is a coin slot that is connected to a timer circuit. When coin is inserted the timer is activated and a relay will turn on. I want to put the circuit to this relay output and connected to the pwr button of the PC. Hoping for your assistance,

But verses most MP3 players, I would want this to pause when it does not get power, not stop and then restart. I know I need a power source to the MP3 player to keep it's spot in the song when it's paused, but it's critical it has a play/pause function that is dealt with through a power source going to/through it.

Which wire goes where (emergency stop button)? Answered

I'm trying to wire up an emergency stop button. Australian power outlets have 3 prongs, active, neutral and earth. My switch has 2 connections, one Normally Open one Normally Closed.  I think I need to have the active line connected to NC (so connected when the switch is in the ON position) and the neutral connected to NO, and the earth remaining connected regardless. This should mean that when it's on the Active line is connected to ground and this the power is on past the switch. When the switch is OFF the neutral is connected to earth and it is safely off (any remaining power in devices connected to it can drain to earth). Am I right in thinking this? or is there something I've overlooked? I am also aware that mains power (240V AC in Australia) is deadly, and not a good idea to play with unless you are a qualified expert. I do intend to have this checked before use, however I would like to have a proper understanding before I go any further. The emergency stop button I have is rated for sufficient volts and amps to use on Australian mains power, and is suitable for the intended use (before a corded drill or circular saw).

Is there a way to power this led?

So I bought this torchlight (Supwildfire 50000lm) it says is a Cree XML T6 LED with a total of 15 LED (not sure cause no Cree branding but from what it looks like it is indeed XML LED). So the funny thing is I burnt an unknown controller on the LED driver by inserting the wrong power adapter. But the torchlight still works by twisting the head to on/off, just cant on/off, brightness control using the button and battery monitor. Now I was wondering is there a way I can buy a led driver or what to look for that supports this many LEDs and still have the functionality of brightness control etc? as i saw there are LED drivers design for DIY Cree LED torchlight (Example: See pic with blue title bar) but I wasn't sure will it be enough to power this many LEDs or will the driver die because of overcurrent.From what I know the unknown controller is supposed to control LED brightness, on/off, and monitor battery level and the display. From what I measure using my multimeter the LED is getting 2.6V if the LED is on, if it is not connected to the board, the board is outputting 3.6V. Also using diode mode I'm getting 2.320V on the LED. As for Amps, I think it is not outputting right as I only measure 0.44A (440mA), or maybe it could be that it is on low brightness.Battery: x4 18650 3.7v li-ion in parallelThere's only 1 9926a mosfet on the negative side x4 R100 SMD resistor in parallel on the positive side

Automotive Power Loss Annunciator

The photo shows what I'm dealing with: a sound module ($2.50 including shipping from China) and an automotive auxiliary power cord (cigarette lighter.) The sound module has a "play" button at the end of the yellow wires. The "black box" has two tasks:                 - detect loss of power on the 12V cord                 - momentarily connect the two yellow wires (as if the button switch had been pressed.) So far I’ve been told that some sort of relay and a timer could be involved, but since I’m not a Electrical Engineer, I don’t know the specifics. I know that in the automotive world, there are big, bulky relays, but I'm wondering if there are relays in the integrated circuit world? I really need specifics like part numbers and circuit diagrams. Thanking you in advance for your help.

Timer gadget to press a button (on a dishwasher)?

Back in the days when appliances had real dials and switches on them, you could set the program and then put it on a timer switch so that it would run on off-peak electric. Now that they're all software controlled with soft switches you can't do that unless you either pay a premium for one with a timer or if they have memory to resume the program from a power cut. What I'm looking for is a simple little thing with a timer on it that you stick over the top of the soft power button, and it will press it (unless you can trigger a soft switch like a capacitive switch by sticking a voltage in front of it?) when the timer runs down. Is there a little gadget to do this? or does anyone have plans to build something? I know I could hack a timer into it fairly easily but that would mean voiding the warranty. Any help would be greatly appreciated, thanks.

Supplying power to the PIC12F508 through a transistor.

I'm trying to supply power to a PIC12F508 via a transistor, so it can turn itself off once it has finished working to save power. The Idea is for the push button to supply power to the chip, which sets GPIO5 high on power up, so turns on the transistor, allowing power to continue flowing to the chip after the button is released. The PIC turns on correctly when the button is pressed, but will not remain on, despite power being supplied to the transistor from GPIO5. Another possible issue is that while the chip works properly, it continues to put a high on GPIO4, lighting the LED while VSS is disconnected. I have checked that the code functions correctly, and have tested this without the additional lines from the programmer. Any suggestions would be appreciated.

Power supply problems for my project

Hi everyone. I'm stuck with power supply problems in my project. My project is a drink dispenser (cocktail machine) with water level indicators. I was thinking of putting 4 water pumps connected to relay modules, controlled by Arduino or microcontroller (something like attiny). The microcontroller would receive a command with 2 push buttons (tasters) and depending on the button pressed, it would combine 2 liquids from 2 tanks into one glass. Now, the code isn't a problem. I need to add a liquid level indicator to the circuit (4 indicator circuits for 4 liquid tanks). Now, the pump I was thinking of buying is rated 5V and the current draw is about 150-250 mA. Attiny2313 operates on 2.7V-5.5V. I found the water level indicator circuit also rated 5V ("https://www.electronicshub.org/water-level-alarm-using-555-timer/" but I was thinking about the one without 555 timer). Now, my question is, what is the best way to power all these components. I was thinking about getting a 220V to 5V 2A PSU adapter ("https://www.ebay.com/itm/AC-110V-220V-TO-DC-5V-12V-24V-Switch-Power-Supply-Driver-Adapter-LED-Strip-Light/152134115704?hash=item236be66178:m:mnohYz4NZlT_Dq5l5lWNUMg:rk:1:pf:0").

I would like to create an led powered by batteries that can change from Green to Yellow to Red and off.  I can use either one RGB led or 3 different leds (Reg, green and  yellow obviously) If having a yellow light makes this more challenging, then I can change the yellow to blue.  Do I need a controller? Can I just use wires and resisters? I would like to keep this as simple as possible to start out.  The whole idea is to have someone be able to either turn a 4-position knob, or push a button to change the color of the LED.  I saw another question on Instructables about this topic, but I could not find any solid answers.  Thank you for any help you can provide. If you need me to provide more information just ask. Thanks again.

Pololu pushbutton power switch module control issue

Hello all: I'm using the low-voltage version of the Pololu pushbutton power switch module to power up/down an Arduino Mini project.  You can see it here: http://www.pololu.com/catalog/product/751/resources It works great, with an exception; if someone presses the single Pololu power switch while the Arduino is ON, it powers it off again. This may be normally what you want, but it isn't in my case.  I'd like the circuit to act like this: 1- wait for button press 2- push button 3- Pololu applies power to Arduino 4- Arduino boots up, loops until 30 seconds has passed.  After 30 seconds, send POWER OFF signal to Pololu. 5- Pololu powers Arduino down. 6- goto 1 It works like that, BUT if someone presses the button again during that 30 seconds, the Pololu powers the unit off right away.  I'd like to somehow disallow that, electronically. Anyone have any ideas? Thanks, Jim

Im looking for a simple circuit that shorts an mp3 players play button briefly

For a Halloween project, barking dog head need a circuit that when powers on "presses play" (will solder wires onto play button switch just needs to be a short pulse to get the unit to play the circuit will need to be triggered by a 6v dc motor starting...and can use the same power as the motor to power itself... pretty straightforward  motor comes on - powers circuit - circuit shorts play button for a quick pulse - mp3 player plays sound clip - people jump and scream thanks in advance

Star Trek Phaser, power bar LED sequencer circuit?

Hello to all,  I am currently re-building a Star Trek type 2 phaser, if that means anything to anyone. I would like to know how to create a circuit that does the following: There are 16 LEDs in two rows of 8. I would like to cycle through them one after another with 2 button switches. ie press a button on the left and the first LED comes on. Press it again and the next LED comes on. Press it a third time and the third LED comes on. and so on. At his point there should be 3 LEDs on. Then, press the right button and that third LED goes off. Press again and the second goes off and so on.  Hope this isn't to long winded. Below is the link to a vid of what I am trying, not very well, to describe. http://www.youtube.com/watch?v=BLYiVdC7Iv4  I would be grateful if anyone could help me out on this. I have searched the web with no luck so I thought I would sign up to my favourite electronics website and ask.    Thanks,

"nuke switch" to power up laptop?

I have been searching the web for so long trying to find a way to do a potentially awesome mod. I have a Toshiba Satellite® L755D-S5204 laptop, and I was wondering if I could (and HOW to) use a "nuke toggle switch"  to power it up or shut it down, and hopefully from USB, as I loathe taking apart computers. The reason is that sometimes I end up crashing my pc from running too many things at once, so I figure if all I have to do is flip a switch, it would be easier than holding the power button for 5 seconds to shut down and another 5 or 6 to power it up. Plus, I think it would look cool. Any suggestions appreciated, thanks
