Pin 4 (reset) is connected incorrectly. Take a look at this page for how to connect it correctly: http://forums.xisto.com/no_longer_exists/

Through my incredible levels of awesomeness Or that moderators don't appear to be subject to the filter...

The reset (pin 4) is normally connected to the input power supply by a 10k resistor, and then connected to ground when you want to activate the "reset" part of a bistable circuit (between pin 3 and ground). Make sure you've connected every other pin of the 555 timer correctly, and that there are no shorts. If that doesn't help, post your circuit diagram and we'll take a look.

That's a blue *BLEEP* (cyanistes caeruleus) isn't it? Have you not seen them in Slough before mrdee?

Hi. To make a thread you just need to create an account on the forums. After that, choose a section and start a new topic about anything you like - simple as that! There are a few sections that require a moderator to check your posts first, so bear that in mind if your topic doesn't appear instantly.

Set up a secure wireless network (secured using WPA-PSK2), ensuring the signal can be reached from the waiting room, obviously. Set the security password to something unique (companyname-public) and either give the password to customers, or put posters on the wall revealing the password. This prevents random people on the street using you for free WiFi. Alternatively, if you're happy for anyone (not just your customers) to use your Internet connection, create an unsecured wireless network and anyone will be able to connect.The exact steps to do this depend on the make and model of router you have. Check the manual or online documentation for further help, or post the make and model here and we shall find out how to do it.

Any compact digital camera is, unfortunately, going to take a while to start up as the lens has to extend from the body. The speed at which continuous shooting can be performed is often down to the memory card you use in the camera, rather than the camera itself. Remember that larger pictures will take longer to save - so the higher the quality you shoot at, the lower continuous shooting speed you'll have. Batteries are also something you will have a problem with with any camera using AAs. If you can, find a camera that uses its own rechargeable battery - you'll find it lasts a lot longer than AAs you buy from the supermarket. Alternatively, buy higher-power batteries such as 2500mAh rechargeable AAs. This should keep the camera going longer, plus being rechargeable means you won't be paying out for new batteries all the time! So far I have been a fan of Kodak compact cameras and Nikon for both compact and SLR cameras. I would recommend either brand, but prefer Nikon wherever possible. The Nikon L120 for example seems to do everything you want: http://www.europe-nikon.com/en_GB/error404.page I would also strongly recommend going to a camera shop to try the cameras out. You'll get a sense of how long they take to switch on, how hard they are to use, etc. You can still go and buy the camera somewhere else if you want. Alternatively, if you can get it cheaper online, tell the staff in the store - they are usually happy to strike a deal!

Having had a bit of time and some nice weather recently, I've been out and about with my camera. This is probably the best shot I came back with. Any comments, critique, improvements, etc. would be most welcome - I'm still learning, like we all are! Sunset at Pitstone Windmill by Rob Valkass, on Flickr

Datasheets do tend to be a bit confusing to start with, but they can be very useful Each version of the voltage regulator has a table outlining its electrical characteristics. Each one lists the output voltage as valid over a range of output currents: 5mA to 1A. As long as you keep the output current draw within that range, you can expect the voltage regulator to hold the voltage steady.

If you've got the datasheet for the regulator, that should tell you. If you could post a link here, or upload it, that would be great.If you're just powering an LED, however, the current shouldn't go anywhere close to 1A, so there should be no need to worry.

The circuits in your house do not normally connect to earth, but to live and neutral. The earth connection is only used to discharge current in an emergency (such as the live connection touching a metal part of a case). This also normally causes the trip switch to trip, cutting power. The earth is actually a pretty poor conductor - it simply acts as a safe low-impedance route to send dangerous currents out of your home wiring and devices.Having said that, it is possible to run a circuit through earth. All you need to do is overcome its resistivity with a strong enough voltage and current.

That's not something we have any control over unfortunately. OpaQue is the only one who seems to have control over the myCENTs system. If you're worried submit a support ticket and someone should look into it. Again, we have no access to the code, so there's nothing we can do. However, it does seem that the problem exists on other forums, suggesting it is a bug with either Invision Board or a common modification to it. The errors don't seem to be affecting the functionality massively either. The same thing happens to me occasionally. The forum also likes to ignore the time I last visited the forums, so the list of new topics is often wrong for me. I just keep signing in - so far I haven't found a cause or workaround. Yup. Pages take an age to load, and you're often left with a blank white page when the page has finally finished loading. Nothing we can do - just keep reloading the page and hoping for the best. I had that problem on an older version of the forums. I believe it was a problem with Invision Board that was eventually fixed, but I could be wrong. Try different browsers, disabling extensions, etc. to see if any of those are causing issues.

The datasheet for that device explains how it expects to receive and transmit data. You would need to create a circuit to transmit that data over a serial port. I remember a friend of mine made a serial port digital thermometer very simply, and then used a serial-port-to-USB converter to actually connect it to a PC. If you're comfortable programming communications over USB, I would use that approach if you could, as the hardware is much easier to create for a serial port than a parallel port or USB connection.

The first error involves the function krsort(). This is a function that sorts an array in reverse order by the key elements (key reverse sort). It obviously expects to be passed an array to sort, but in this error message it has been passed absolutely nothing to sort. Not being familiar with the latest code for Invision Board, I'm not sure exactly which bit of the code is causing this error. The other two errors are caused by the first error. The Invision forums contain a bit more information: https://www.google.co.uk I haven't spotted that. For me the favicon is blank until the forum's specific favicon is loaded.

I bought my first DSLR a while ago, and opted for the Nikon D90. I spent a while in shops handling both Nikon and Canon's offerings, and I felt that the Nikon layout, shape, etc. just fitted me better. I think right now that will be the main factor in choosing which brand to opt for. The cameras pretty much have all the same features (but with different names) across the two brands, and perform just as well, so you won't regret either choice. A key point to note is that the video recording on any DSLR suffers a fundamental flaw - horizontal tearing. Due to the way video is recorded from the sensor of a DSLR, horizontal tearing is a massive problem when panning any shot horizontally. This can make motion look very wavey, or in the worst case cause a clear divide across the middle of a shot. If you are mainly focussing on video you would be better off getting a dedicated digital HD video camera.

The two equations are equivalent. You just need to remember the key difference between velocity and angular velocity. The magnitude of each of them can be related by the following equation: |v| = r * |w| Or, if you're happy with vectors: v = w x r where x denotes the vector cross product, and r is the vector from the centre of rotation to the body's centre of mass.

The equation for centripetal force in this instance is: F = mr|w|2 Where F is the force, m is the mass, r the radius and w the angular velocity. Your data give us this (converted to SI units): m = 0.55kg r = 16.8cm = 0.168m w = 88.2RPM = (2*PI/60)*88.2 rad s-1 Plug all those in to the equation: F = 0.55kg * 0.168m * ( 2 * PI * 88.2 rad s-1 / 60 )2 F = 7.8 N (to 2sf, the greatest accuracy given)

Of course steps can be taken to speed the forum up. I've just run YSlow on the forum to see exactly why it runs so slowly. Remarkably it scores a C overall, but with quite a few components scoring F. The forum currently makes 26 HTTP requests per page load, which is a huge number and could be cut down to two quite easily by combining all external Javascript into one file and all CSS background images into one file. Stunningly, each page uses 87 external elements - a vast amount! That could also be cut down to improve page load times. The mistake has been made that 84 of those do not have "expires" headers, so they have to be loaded every single time you load a page. Adding the headers would let your browser cache the files so you'd only need to download them once in a blue moon. ETags are also not correctly set up, meaning the browser has no way to verify if its cached version of a file is still good, so it has to fetch a new version on every single page load. Content is also not sent with gzip compression, increasing the amount of data that must be transferred. This mainly affects the Javascript and CSS components of the pages. The Javascript and CSS could also be "minified" to further reduce the page load times by reducing file sizes. Good old fashioned streamlining can also be applied. Each page load requires downloading 2 170kb Javascript files, which should probably be cut down. If all that doesn't help, the problem could possibly be due to a lack of sufficient hardware. If the site is really that popular that the server can't cope with the requests, then more hardware may be required, either in the form of more servers, or a wider Internet connection for the server. This is something we can't really speculate on without server load statistics. Xisto owns KS, yet still calls it Xisto on their homepage: http://forums.xisto.com/no_longer_exists/OpaQue owns Xisto, so he's pretty closely related with the forum and the business. Definitely. I have recommended Xisto/Xisto - Web Hosting/Xisto/Qupis to many people in the past, many of whom trust my recommendation and signed up. Now, I don't recommend Xisto/etc. They have therefore lost business. I imagine other members do the same. There used to be five pages of new posts waiting for me each morning. That was great - there was loads to read, and always something to talk about. Now, there are about five posts each morning. That's a shocking decrease. Recently it's picked up again, but 95% of the posts are spam Unfortunately, due to the nature of some of the spam, I now cannot moderate the forum in any public place or on any unsecure Internet connection. That has cut down the time I have available to moderate the forum, and I apologise for that. If the admins have abandoned the forum there is nothing we can do, as there is no way for anyone to get into the admin controls to change anything. All we can do is hope they come back and sort things out. You could also try the more direct approach of writing to Xisto to ask questions. The address, according to the Xisto website, is: Xisto Corporation 218,Shiv Center, Sector -17, Vashi Navi Mumbai-400703,India It's only £0.67 for an airmail stamp so give it a go Part of me wants to leave the spam to see if OpaQue/Buffalo actually notice. I'm sure it would affect revenue eventually. I just can't bring myself to do that when there are people still here using the forum.

Thanks for the reports. I'm doing my best to delete every spam topic I come across, but there are a few I miss which your reports direct me towards. I thought the registration process did include a CAPTCHA? Most of the spam before this recent flurry was from humans manually creating accounts and then copy-and-pasting spam into posts. Now, it seems to be entirely automated. Either the registration process has been changed making it easier for computers to register accounts, or they've managed to crack the existing safeguards. In either case, the registration process needs to be changed to make sure computers can't automatically create accounts. I'm in the UK, so it will appear to you in the US that I'm logging in at weird times to deal with the spam. I am doing everything I can to delete every spam topic I come across. However, it currently takes anything from 30 seconds to 2 minutes for a page to load. Deleting a topic takes 6 page loads (three to open the list of reports, open an individual report, mark it complete, and another three to load the topic, mark it for deletion, and confirm deletion) so can take anything up to 12 minutes!!! With the current volume of spam it can take hours to wade through it and delete it all. I am trying my best though, honestly.

Firstly, how do you accidentally pull a processor out? Depending on the socket that may well have caused some permanent damage to your processor and the motherboard (if you didn't intend to pull the processor out). When you say it shows a black screen, do you mean the screen is on and the computer is outputting every pixel as black, or that the screen never comes on (implying the computer isn't sending any output)? Do fans spin up? Are there any lights on the motherboard? Is there a power button on the motherboard that you could try rather than the power button on the case? Answering these questions should help us diagnose the problem.

Nope, once the myCENTs are in your billing account there's no way to get them out. All you can do is spend them on hosting and domains at the moment.

You've only actually got one error there - the first one. That error is causing the others to appear. Have you had a look at line 754 of the file /home/prismwar/public_html/admin/sources/classes/useragents/userAgentFunctions.php to see if it is missing a right parenthesis as suggested by the error? Do you remember editing that file? Can you compare the version that you have uploaded to your web space to a copy of the file from a backup that you know works?

Sorry, that comment had me laughing my head off! Euro NCAP is a standard devised by the UK Department for Transport (the name stands for European New Car Assessment Programme) for measuring the safety of new cars in collisions. The safety of both the occupants and pedestrians that may get hit by the car are measured. Each car is then scored on a "star" system (ie. given a score out of 5). Higher ratings mean the car is safer. So, for example, a car may score four stars for passenger safety and three stars for pedestrian safety, implying the car is above average for the safety of the occupants, and below average for the safety of pedestrians who might get hit by the car. More information can be obtained from the Euro NCAP website: http://www.euroncap.com/en
