Here at Infomania.co.uk we’re dedicated to digging out those bits of information that you’ve always wanted to know. One of the things that is really difficult to find out is how much energy domestic appliances actually use. You can usually find out the power rating easily enough – if only by reading the label on [...] Here’s a hairdryer that got to the end of it’s useful life. As you can see they are really pretty simple. Basically all you’ve got is a heating element (behind the front grille) and a fan to blow air around it. Of course there’s always an on/off power switch. This one has a couple [...] Oops, I dropped my hard drive! Well to be truthful it had packed up so it wasn’t much of a loss. And it was only a 1Gb drive in the first place. As you can see below once the lid is off all the major mechanical components are exposed. You may have seen elsewhere that [...] Here’s another in our line of technology autopsies – a GSM cellphone. This one came from a car boot sale but had no subscriber identity module (SIM) card so it wouldn’t work. The SIM card slotted into the back of the case, between the battery and the main printed circuit board (PCB). As you can [...] Let’s take the example of a single-band UHF antenna. This looks a bit like a fish skeleton. The “bones” are arranged in pairs on opposite sides of a central “spine”. The bones near the front are shorter than those near the back. The critical difference of course is that an antenna is made of metal. [...] MP3 compressed sound files are finally becoming popular with online music stores, now that DRM is on the way out. Although MP3 compression is not quite as efficient as AAC and WMA it is good enough. The files are much smaller than WAV files and audio CD data files - around one tenth of the size, depending [...] The Philips DRT1500 set-top box is a great Freeview receiver but suffers one problem. It is only possible to add new channels to the channel lineup, not change those already tuned in. As channel names and numbers change the channel list can get quite out of date. It is possible to reset the Philips receiver [...] A wide range of sensor sizes are used in cameras today. The size of the sensors is not related to their resolution (measured in megapixels). The smallest, 1/3.6″, has a tiny light-sensitive surface of only 4mm x 3mm. That is just 1/72 of the area of a 35mm frame. Needless to say there are some [...] Welcome to Infomania The website was previously running on a CMS (content management system) which proved to time consuming to manage. Hopefully the new platform will allow us to concentrate on postings, hints and tips on a more frequent basis. We’ll transfer some of Infomania’s original articles onto this website soon, so some of the more valuable [...] |

Photo fading – CDs, DVDs and prints
You might be surprised to know that you can’t even be sure the CDs you burned of this year’s digital photographs will last five years, let alone the inkjet prints you made. [...]
