Enquiries We receive a large number of enquiries. Please note the following before writing: Readers who are having problems with one of our published projects will get priority attention, but, because we are busy people, you may experience a considerable wait. We cannot guarantee a reply to any letter, although letters in the above category will not normally go unanswered. If you want a personal reply, please include a stamped, self-addressed envelope, or, if writing from outside the UK, please send one ( Europe) or two (elsewhere) International Reply Coupons (obtainable from post offices). Overseas stamps are not acceptable to the post office for reply mail. Letters without return postage will not normally receive a personal reply. Letters may be published with their replies on our letters page, whether or not a personal reply is sent. Any letter will be deemed eligible for possible publication unless non-publication is specifically requested. Obviously, an enquiry of general interest which is eligible for publication is going to be processed that much faster if we want to print it. When enquiring about problems with projects, please keep your letters as brief and precise as possible, and include as much information about tests, measurements, specific anomalies and observations, overheated components, etc. for our assistance. Without such information it is impossible for us to advise. Please do not write before carrying out all relevant checks. Many project problems are caused by simple factors like solder bridges, dirty component leads and contacts, etc. We cannot normally advise on modifications to circuits, or on circuits which have been modified, used beyond their published specifications, or had components substituted. You can of course try your luck, but don't expect to get lucky too often! We cannot design circuits, even simple ones, for readers. We cannot deal with technical queries over the phone except in the case of direst emergency. We cannot normally reply to enquiries about any subject except as specifically covered in the magazine, or matters of general electronic interest. If you are combining an enquiry with an order for a back issue, subscription, etc., PLEASE WRITE THEM ON SEPARATE PIECES OF PAPER otherwise one or the other may not reach its correct destination. Yes, we do like to receive comments, suggestions and criticism from readers, about any relevant subject. As space is limited, letters may be condensed or altered for publication, subject to not mis representing the writer's intentions. Back-numbers Back-numbers are held for one year only from the date of issue. The current cost of backnumbers is £ (x 1.4 USD) 1.50 each. Back-numbers for any particular month may go out of print before twelve months has elapsed. The back-numbers page which appears regularly will attempt to keep abreast of availability. but this is not always possible. As an alternative, photocopies of articles from all backnumbers of EM and Hobby Electronics are available from the Photocopy Service. Electronics Monthly, No. 1 Golden Square, London W1R 3AB. Price £ (x 1.4 USD) 1.50 per article (two part articles count as two articles). Please give the title of the article, title of the magazine, month and year of publication. Checks and money orders payable to ASP Ltd. Some Good Advice These are a few points to bear in mind to help you get the best from the information EM offers: 1) Many readers of electronics magazines observe the wise custom, especially with large, complex projects, of deferring their construction for one or two issues to see if any misprints or errors are discovered. This is less significant on simple projects, but is still prudent if you are not confident in your ability to sort out simple errors by yourself. 2) Please do not respond to advertisements in issues older than six months without first contacting the suppliers by phone to see if their stock and prices are still current. Special offers especially often run out after this period. 3) If planning to build a project which contains an expensive or specialized component or components (this will usually be indicated in the Shop Box), make sure you have obtained this piece before investing in the rest. If there is a shortage of the component at the time, you will not have to sit on a pile of expensive hardware waiting for it to become available. This applies doubly to projects in issues older than six months. Some components become obsolete, or change their specifications, over a period of time, and may be completely non-available. Check these first. Also see: |
