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.

Timer to flip light switch?

I need a timer that will mechanically operate a wall switch for a light. I've seen a device years ago for sale in the various "gadget" catalogs that did exactly this. It attached to the trim plate around the light switch using the 2 trim plate screws. A battery powered digital timer operated a mechanical slide to operate the wall switch. I can't find this device anywhere now. I know there are many electronic timers that replace the wall switch and have timer capability, most do not work with compact flourescent lights. I'd really like to find a timer for sale or get some ideas on a simple way to make such a device. Thanks for any help. Scott

How to fix the switch on a neon sign?

Hi everyone! I have one of those nice Heineken neon sign that i've found in a antique shop. I payed only 10$. The thing is, the guy told me there's a little problem with the switch... I was thinking that I could fix that. When I opened the plastic box and saw the switch I thought to myself '' how am I gonna fix that'' I bought a switch that you install directly on the wire, looks like the one we have on the wall to open the light in a room. (You know the same kind of switch that has a little 'wheel' that you turn to put on or off). I need your help dear Instructable comunity, what should I do, and how? Thanks a million times in advance!! Nick

Help Replace Discontinued Range Hood Vent Fan Switch

The variable speed fan control on my Thermador HT48HQS hood vent does not work and the replacement switch is no longer available.  I'm looking for some help in making a new switch.  The Thermador VTR1000Q motor is mounted on the roof and controlled at the hood with a variable speed control knob. The motor is rated at 115V 60Mz 7.8 Amps. Photos of the switch assembly are attached. From what I understand, the speed control knob is a potentiometer that regulates the speed by proving a range of amps from 2.5 to 8? If I could make a variable speed control that would be great.  But I'd be more than happy to have create an on/off toggle switch or a toggle for low on/off high.  Can anyone help me?

How does one wire a motor so that it reverses automatically?

I'm looking for a relatively simple, mechanical way (by that I mean not using a micro-controller) to wire a motor so that it will reverse direction without being switched manually. The interval is unimportant, and the purpose is to have two spools connected by a loop of string (think reel-to-reel), one of which is controlled by the motor. A low-tech solution would be awesome.

Power supply switch for boombox project...

Could someone help me with some simple wiring questions? I've built a little boombox using a Lepai amp and some speakers. At the moment the back is off the box that houses the amp, so I can plug in a mains power adapter, but I've got a housing for 10 x rechargeable NiMH AA batteries making a 12v battery pack with maybe 20 amphours of life in it. I've only just ordered the batteries so I'll see. However, I was thinking that I'd still like to have a socket that I can plug the mains adapter into. So I was thinking about mounting a DC socket on the back plate, and some sort of switch to select the power source. 1. Does the switch need to be a 3 position one? There's an on/off switch on the front of the amp, so maybe a 2-way switch would be OK? 2. Does the switch need to be some sort of special one because it's switching power. Would something like this one do? 3. The switch has 3 terminals. How do I connect it up? I'll have +ve and -ve from the battery pack, a +ve, -ve, and earth from the DC socket, and a +ve, -ve and earth going to the amp. ...or maybe there's an easier way of doing it? Thanks.

How to add 2 LEDs to my footswitch so I can see if either channel is on or off.

I have a 2-channel Marshall footswitch that I want to mod to mimic their PED802 model with on/off LEDs on it. Scoured many forums for schematics or diagrams or photos, but nothing so straightforward out there. I believe it does not require a battery to power them as it mimics the light on the amp front, but my electronics knowledge isn't so good. Anyone have a photograph of something similar? I think I need two LEDs, two resistors and a couple bits of wire, but that's all I can glean. Thanks.

What switch to use for LED Light project

I have  seen a few build on here recently with installing LED lights on stairs.  I am liking that idea and overall have an idea of what I will do with the lights, but I can't seem to find the switch I want to use. I would like to set this up with 2 lasers or beams.  The idea is that one would be at the top of the stair and the other at the bottom.  They would be in  the wall so you can't really see them.  I only have easy access to one side of my stairwell so I am hoping the set up is something like a beam going to a reflector.  Once a beam is broken, the lights come on and remain on for a short period of time (30 seconds or so) and then they turn off.   The problem I am having is I either find thing like garage door beams that are big and hard to hide and require access to both side of the wall, or beams that only travel a foot and a half at the most.  The stairs are the standard three feet or so.

Replace 3-way light swtichs

  Hi Folks,   I have a small laundry room with two 3-way light switches and no outlets. I would like to replace both switches using one of these options: Replace "master" switch with combo switch/outlet (like Pass & Seymour TM838. Replace slave switch with an Occupancy Sensor Switch. -OR- Same has above but use a regular outlet instead of combo. If I have to I would be happy with disabling one of the switches and just have the Occupancy switch.

Earthwise 50218 corded mower - control switch lever broken

We have an Earthwise 50218 corded mower that we've been very happy with. The only problem is that the control switch lever that is used to start the thing is plastic and broke. We were able to manage with it for a while but then it broke even closer to the base and cannot be used at all. Without this lever, the entire mower cannot start. It appears that the manufacturer doesn't sell a replacement part for this. The only official option was to buy an entire control assembly at $40. Has anyone else run into this problem? Any ideas on a cheaper solution for this simple, stupid problem? (The manual for this thing is here: https://www.powerequipmentdirect.com/manuals/earthwise-50118-50120-owners-manual.pdf)  Thanks!

Speaker switch box (2 x 2 or 4) with automatic ohm balance / adjustment, has anyone got a design for it please?

Hi, I have a cheap speaker switch box connected to my stereo amplifier as it only had one set of speaker outputs. When the smaller higher power demanding speakers are switched the box causes the more efficient floor standing units to shadow the sound which is annoying. The reverse does not happen, but when all 4 speakers are switched on the sound quality drops noticeably, as it would since the ohm matching is not right. I could buy an expensive Niles box but I don't exactly know the ohms for the smaller speakers since they have had the main drivers replaced (the original foam cone supports hardened and cracked in the dry heat of a few Australian summers). I suspect one set on, and one set off is a simple enough device even I as a novice could design it, yes i can, but would just building a better switch box using higher quality switches solve the shadow effect? and I have no idea about the 2 sets on so any ideas - a internet search didn't help much but maybe you call these things differently in the USA?
