At work we have a computer hooked up to a fluorescent microscope and when we are analyzing something on the scope we need the room to be completely dark, which includes turning off the LCD monitor on the computer. But then we need to turn the monitor on again to capture images on the computer, so we are constantly turning the monitor on and off and it is starting to cause some wear on the on/off switch. So my question is: is there a way to turn off the monitor from the keyboard?I have tried setting the screen saver to blank and turn on after one minute, but I hate waiting a minute for it to come on and the mouse is often nudged so the screen saver goes off. And sometimes we use the keyboard to move between microscope filters.This being a work computer, they don't want any software downloaded on to the computer. They don't even want us to change the wallpaper (god forbid). So can this be done with out the use of a program.The computer is running XP.Thanks!

I have equipment that runs off a 12v deep cycle battery, but only one at a time, in parallel it causes noise in the system. We have to switch batteries halfway through the day because the electronics don't work at certain voltages. We currently have to hop in the back of our rtv, unscrew the wing nuts and switch the power cable (positive and negative ring terminals) to a new battery. Id rather make this easier for my crew and found an on/off/on rocker switch that seconds as a volt gauge for whatever battery it is toggled too. Could someone help me out with the wiring configuration using this rocker switch?

I'd like to give up the silicon valley and move on my own land somewhere that is suitable for an off the grid cabin/year round home. Ideal land would be suitable for small family sized garden, be near fresh water and not be a total snow pile like in klamath falls in the winter. 2000 feet above sea level or lower would also be ideal for what I'm looking for. But I'm sure others might like to know how other people have gone off the grid without having to save money for 20 years just to get there.

We currently have a gasoline generator and this provides all the electricity but would like to use renewable resources. We have built an elevated water tank and use gravity but this is only accessible during the summers, we live in Iowa. We haul the water in and bring drinking water we bring (only there on weekends currently). In our county they said we need to have a septic tank. We have an outhouse but no grey water disposal. In our county we cannot allow anything which touches the body to touch the ground so throwing it out on the ground isn't a long term option. Any options we are aware of are OK with the county but we would still have to run it through a septic tank first. This defeats our low budget project. We want to live simply and I have a hard time understanding why it is OK for the cattle lot just up the creek from us to run off from the lot into the creek but our bodies would contaminate our land. (I think the cattle lot already does this as it is sewage washed down to us) We do not currently use any of this creek water. Our cabin is about 1/4 mile away from the creek. Any new ideas?

Ok I'm not really electronic savvy but I can solder and follow a diagram. This is what I want to do: I have a toy four wheeler for my kids. Has one battery and a push button that makes it go. When you release the button it stops. I want to add another battery and push button so when you push the original button the batteries run in parallel. The speed will run the same as with the one battery but twice the run time. (please correct me here if I'm wrong) When you push the the new added button at the same time as the original button it will switch to running the batteries in series so it will be faster running on twice the volts. So i'm figuring I need some sort of on/off/on 6 pin switch and a push button switch but not sure how to wire it exactly. Found this which gets me close but I want to add in the push button switch to make it work instead of the toggle switch. https://www.instructables.com/id/SIMPLE-ParallelSeries-Select-Switch/ The original button is on the handle and you push it with your thumb. I will add the new switch on the other handle. Something like this https://www.ebay.com/itm/5x-Red-Square-Pre-Wired-Momentary-Push-Button-Switch-Reset-1-2-AC-250V-Car-12V/182680718419?epid=11005923516&hash=item2a889e8c53:g:YoMAAOSwr9VZwoA7 Any thoughts on this would be awesome!

We have a lot of LCD projectors at school.As you may, or may not, know, they work by splitting the light from a bulb into three beams, shinging them through three different-coloured LCD filters and them re-combining the beams to form a full-colour image on the screen.One of our projectors developed an odd blotch in the image, and a few minutes' furtle by our IT technician found that one of the LCD filters had packed up - the layers had delaminated slightly.Cost of a brand-new projector - 465GBP.Care to guess the price of a replacement LCD unit?

Hey everybody! I put the clap off bra on Kickstarter to try to raise some funds to have it manufactured. The way Kickstarter works is that I only get the funds pledged if my funding goal is met. This is a good way to see if the clap off bra is actually a viable product. I am excited to see what happens.

Just a question..... In Australia we have a few new changes in laws regarding work hours.... One of which is that an employer can MAKE you work up to 48 hrs in the week... This would be fine if you were paid for them but.... with these changes employers only have to pay you for 38 of those hrs and can give you "time in lou" > Time off for the other 10.... So basically I am forced to work extra hrs so I can have that same time off at their discretion....?? Does this seem a bit weird to the rest of the world or are you seeing similar changes too?

The exact setup I have is a little difficult to explain, but basically I'm designing an extremely simple heat engine, based on boiling ethanol, and need to be able to mechanically alternate the flow of vapour. I have a little boiler, sealed except for a pipe out of which the vapour escapes. This lifts the column of ethanol in the pipe, pouring it into a water wheel which turns. The ethanol then runs back through a second pipe into the system to be pumped up again. It works, and fairly well since I'm not looking to get a lot of power or efficiency, but only if I pinch the tube on and off. This allows the bubbles to collapse, which sucks in more ethanol to replace them. When I release the tube the bubbles rush out, lifting the eths, and repeat. I have two valves to keep the system one directional. So now I'm looking for a way to automate the opening and closing of the gas feed. I've been trying a few things but nothing seems to work well enough yet. The other consideration is that; due to the nature of the larger project, whatever I use has to be extremely simple to construct, preferably from reclaimable materials. 1 second on, 1 second off seems to work best. Any ideas? cheers, Daniel.

I saw part of a show about how to build a wooden shelter using no nails from logs. It didn't look like a log cabin. The sides were split logs held in an upright brace also made of logs. It was simple to make but very hard work as much of it was done with hand tools. But I think modern tools could be used now. ( This was sometime in the 1960's.) Anyone know anything about it? It would be a good thing for off-girders.

Hi People of Instructables! I hope I am posting in the right place. I am looking for a switch that when you walk pass a point it shuts off and when you walk the other way past that point goes back on. For example... I have a flash-light in my hand, when I walk through a doorway into a house the light turns off. I go through the doorway the other way (to the outside) the light turns on. Conditions: It has to be able to do this through cloth as the flashlight could be in my pocket. It can only work when you walk through the doorway but not when standing near the doorway Does anything like this exist? if yes what is it called? I have been searching the 'net and not been successful as I don't have a clue what I am looking for. Any help would be greatly appreciated. Thanks for reading my post! TheLastPrincess

Two years ago I spent my fall semester in Vietnam. While shopping in the markets I often heard the phrase "Same Same...but Different". This usually referred the knock-off North Face bags (mine fell apart after a month) and designer sunglasses that were, according to the vendors, just as good as the real thing, but a little different. Although knock-off often has a bad connotation associated with it, it really just means same same but different. What types of things have you encountered in your everyday life that you've thought, "hey this is just like this other thing I tried"? examples... - the perfume I wear smells just like this designer perfume that is 3x more expensive - this bands has a similar sound to this band; they're a little less known but their music is just as awesome! - the city I live is a smaller/larger version than this other city I visited you got the idea

I am looking to use my computer to turn on and off usb devices (like a LED light) via a computer program. I know that USB devices have a constant five volts of power to their ports, and that the normal way to turn on or off a device is using a microcontroller board. I've looked into buying such a board, but they are prohibitively expensive for my project (over $30) and require high level programming skills. I know a little Visual Basic programming and that is about it. With usb devices so numerous and cheap, i am sure there must be a very cheap usb device that can be hacked. Ideally, I'd like to be able to have the computer run timed on-off events and remotely control these over the web. Any help would be great.

Trying to build a sequential fade on when power is applied and fade off when power is removed LED circuit. I have problems with power loss by the end of the LED string. The current layout has 4 LEDs that will fade on one at a time until all 4 LEDs are lit and then the fade off in reverse order. My original idea came from osgeld's No CPU / MCU led pulse-fade circuit. Any ideas on how to keep the power to the LEDs consistent from the first to the last? The idea is not needing to program any chips. Once I/we have figured out how to complete this circuit as desired, I will post it as my first Instructable.

It came with no instructions. I've looked at a couple similar boards and thought I knew how to wire it up, but I am not having any luck. I can't figure out how to wire up the power and the led light strip I have to get the IR remote to turn on and off. I thought it was a gate sort of thing where you put the positive and ground on either end for the power and then wire up the ground of the LEDs to the same ground as the power but the positive to the center post. But using my multimeter I can't see it turning anything on and off. I used my phone camera to see if the remote is working and it is at least IR blasting, I can see the light. So does anybody know how to properly wire one of these up? EDIT: Ok, the two pin terminal by the LED receiver is the power in. The connector I was using before was bad. But still trying to figure out how to turn on/off the strip now. The gate is working as expected with the left and right always having power but the center and ground only have power when the unit is on. But it's only getting about 1 volt out when on. My power source is putting out 12v, 2 amps. Is that my problem? I have to say I'm not very good at this yet, and I can't really tell what the numbers on it are telling me. I thought it could do 12 volts out though.

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.

Hi I am working on an Image 15.0 R Treadmill. As soon as you start it , it shuts down as if the circuit has been interrupted. I unhooked the drive belt so that there was no resistance to it and it does the same still. The speed sensor seems to be working okay so I pulled the controller (board) and tried re-flowing it. as I flip the treadmills switch on not starting the treadmill-just turning the power on the motor runs for about 3 seconds. Because the cover is off while I am working on it I can see that during that 3 second window the motor has a spark (bolt) from one of the bolts to the post (I think stater) the one that if the motor were disassembled the part spinning inside the copper wind. I don't remember what it's called (armature?) Anyway this arching does not re-occur unless I completely unhook the board once more and re-assemble. After re-flow the motor still just begins to load (start) bumps about 1/2 a rotation and stops. I read an article here that Iceng had commented about bringing his P.M. D.C. Motor model # c335483304 back to life......it is the exact motor....my girlfriend has been on me about fixing her treadmill so here I am. Anything would be of great interest and help to me. Thanks a million in advance. Troy
