Any chance of an extension for the Dead Computer Contest?

The reason I ask, and perhaps I'm being selfish, is that I'm waiting for some PCBs to arrive from a board house in China.  Normally they would have arrived by now, but the Chinese New Year delayed all of the shipping times! No problem if it can't be done, and I wouldn't expect an extension just for me, but I thought I'd ask anyway.  I *might* be able to finish by the deadline anyway...

Replacing switch and extending them.

I have this extension cord from panther, Now, I am planning to replace its rocker switches to toggle switches and extend it because of a wooden table project. This wooden table will have its power control panel mounted on its front and the power outlet will be hidden inside the table. My idea is just to copy its wiring for the new switches once I acquire the materials needed . Here is its inside btw.  My problems are I don't know if this idea of mine will work or if it will, what kinds or specifications of toggle switches and wires I'm gonna need. Once I thought that I could just make an ordinary multiple outlet/extension cord with individual switches but I need the panther's features. So that I wouldn't have problems in breaking the appliances connected to it due to some electrical problems. I have almost 0 knowledge when it comes to electronics.

Instructables Lookup Firefox Extension

Does anyone here have experience with Firefox extensions? I think this would be useful.When a word is highlighted and right-clicked, on the context menu, there would be an option of "Lookup in Instructables." When clicked, it would open a new tab for Instructables, and run a search for the highlighted word. It would be similar to Wikipedia Lookup, but for iBles, not Wikipedia. Is anyone up for trying this? I know nothing about how to do it.

Hello, I'm having trouble finding a list of permitted file types for attachment to articles. I understand there are some which work, like .svg, .pdf, and the image extensions. The reason I ask is that I wish to attach Autodesk 123D Design .123dx files, but it doesn't appear to like it. Thanks Greg

Light Socket Extension help

Can you help me find a safe way to build a cheaper version of this:   Here's my situation: I want to convert double-lamped can lights into adjustable spotlights without making any permanent changes other than unscrewing a lightbulb and replacing it with something else.  It needs to be able to go back to a lightbulb very easily.  The cans stick out from the wall and each socket is oriented vertically, so one points up and one points down, effectively washing the wall up and down with light.  The wall of 8 or so are wired so the tops are all on one circuit and the bottoms are all on another circuit. The item from Lowe's works OK, but is $17 and more flexible than I need.  Here's what I started to put together:   At the top is a 100W Par38 spot light, screwed into a single outdoor metal lampholder.  That is attached to a 1/2" pipe (PVC or metal), about 12" long.  Now, at the bottom of the pipe, it needs to screw in to the socket to get power.  I either need to get an E27 lamp base onto that pipe, or use a two-blade outlet adapter that screws in, and get a two-blade plug that is rigidly fixed to the pipe.   Is there anyway to do this that the NEC would smile at?  Absent of that, a way that is still safe and secure, and safely removeable without changing the existing light socket arrangement?

360 Wireless Adapter and USB extension cable

Hi everyone on instructables, I having a xbox 360 problem and was wondering if anyone has some advice. ( I posted on the xbox forums but I'd also like some advice from members on instructables since many of you have knowledge in electronics. ) Anyways so here is my problem... I recently just bought a 360 Wireless Adapter so I can play on Xbox Live, but the signal strength is weak because the unit is in the basement and the router is on the second level of the house. Can I attach a USB extension cable (a male and female end) of 15ft to the console onto the adapter so I can relocate the wireless adapter to a different location in my basement where the signal strength is stronger. Can this cause the unit to overheat or cause any other damage because im making the console work harder adding the 15ft usb cable?

All about Extension Cords: Building & Wiring

I just want to make sure of the right way to wire an extension cord. I already searched on the internet and there were no concrete answers or tutorials to the type of extension cord I'm building. Note: I live in East Asia and we use a type A outlet (220V). I also hope you guys will use this thread to post other diagrams of extension cord types in different regions of the world to help other viewers too. Thanks.

Cable extension parts

I am working on a project involving a Presario V5000 laptop (well mainly its innards) and would love to find extension cables for some of the components.  For example, the keyboard attaches to the motherboard via a 24 pin flat ribbon-like cable (see example image).  It would be great if I could get a simple extension piece (male to female) to give me any additional length, but I cant seem to find anyone that makes this, or what the techincal name is for that type of cable. (is it even a cable?  Is it a flexible circuitboard?) Anyone aware of a good vendor for hard to find laptop accessories like this??

Flat Wall Plug Adapter? (for DIY extension Cords)

There is an extension cord (3 wire) which has a flat wall connector - great for tight spaces.  I've bought some over the years (about $12 each at Amazon) - but want a supply of the plugs so I can make my own custom/length cords.  I looked at a few electric parts places but no luck.  Any ideas/sources for a less expensive flat plug adapter? One option  is to replacc the wall outlet with a recessed outlet - but that does not work for me. thanks

Please help me about my thesis.

Hello. I'm currently taking an Electronics course. I have a thesis. So here's my thesis idea.The purpose of my thesis is for children's safety. A child will have to wear a watch wherein it will send off signals continuously and when the receiver which is inside an extension receives the signals emitted from the child's watch it will trigger the outlet to switch off then the appliances plugged in that extension will be off. As for the extension I'm gonna put a relay circuit inside an extension wherein any appliances could be plugged in. My problem is what transmitter and receiver am I gonna use to trigger the circuit to switch off? Should I use Bluetooth? But it doesn't auto-connect as far as I know. Can I use Zigbee shield? Does it have transmitter and receiver? What microcontroller should I use? Please help me. :( Thanks in advance!

electric house windows

If windows could be closed and opened automatically, it could extensively help regulate inside air temperature- a big boon to those of us with no AC. Coupled into a remote-control house, it might reduce electrical consumption and/or increase comfort extensively. I am imagining an add-on to the type of windows that slide up and down; seems the type that opens with a crank would be very easy to retrofit, but they aren't very common, and not very insulating, in my experience.

More Extensive Profile Customization

I think it would be fun to be able to personalize our public profile pages. Uploading custom images to use as backgrounds adds so much personality to a profile. Changing the "color theme" lets users put out clear messages like "I'm professional", "I'm cool", or "I love colors so much omg". All of those are valid messages. Thoughts? Might this be possible? UPDATE: Kiteman has pointed out that choosing which six projects show up on our overview pages would be awesome.

The Electronic Goldmine  has a rare to find component. "Tiny audio optocoupler is about the size of a pencil eraser and has 4 leads. These are used extensively in audio compressors, audio level controls, audio limiters, expanders/noise gates, guitar tremolo effects, guitar amplifiers and music effect boxes. Inside the black epoxy case is a 2 lead photocell (not a photodiode or photo-transistor) and a 2 lead LED. This is why the device finds extensive use in audio applications (photocell instead of photodiode). The LED requires about 10-16mA current and the resistance of the photocell varies from 150K up to megohms when the LED is off to under 400ohms when the LED is on." A

Fun (Techie) Question(s)...(will be continued if there is interest) This is #1:

Engineering problem: The problem is to take an extension cord (you will have to figure the gauge at some point), and wire in 2 more "sockets" (for plugs) in series or in parallel, plus 3 neon bulbs in such a way that they only light when something is...#1: plugged into the corresponding socket &#2: the something (appliance, light, etc) is turned on, in other words, when that portion of the circuit is closed. The cord will be for very light rated appliances or bulbs. Nothing beyond a kilowatt althogether. Specify extension cord wire gauge and anything else needed for the project and it's necessary rating / part number. And most of all, have fun....and don't over think the problem ;-) OK, I blew it.....I knew I had created a similar cord to the one I described, and finally found it....only it doesn't do what I said it does. I merely had Neons that come on when the cord is plugged in.......this is what happens to your memory as you get older LOL.

Hardwire IR Extension to amplifier

Hello Instructables. This is my first post and would like to begin by saluting the work you all do, I love receiving the email at work showing the weeks projects. My problem, that I hope somebody has a solution to is this... I am building a false wall to house my fish tank and TV, ps3 etc however my amplifier is too large and does not fit into my project. The only way round this is to house my amplifier in the loft. In the wall I want to place the IR remote control Sensor. I don't really want to pay out for those 'eye's' you can buy online (nor do i think they would be compatible with my model of amplifier) so was wondering if i could just use some ordinary electrical cable to extend the sensor? I was worried cable might not allow this as it would probably add extra resistance to the circuit. Does anybody have a solution or suggestion that involves spending little or no money please? Thank you very much! Frankie
