ISSN 1030 -2 6 6 2 * Recommended and maximum Australian price only . 2 SILICON CHIP PUBLISHER'S U'l-l'ER Editorial content: juggling the mix isn't easy At a particular time in the production cycle of SILICON CHIP, we have to make critical decisions on the editorial content of the issue. As time goes on, we are finding these decisions quite difficult. Do we leave out a feature article so a project article will fit? Do we run a project article in one big slab rather than in several episodes? Can we afford to run more readers' letters and so on. Questions like these are difficult because we are trying to cater for such a wide range of reader interests. Each month we try to include a good range of articles but we are not sure just how they will be received by you, the reader. What we think is great may not necessarily appeal to you. We'd like to hear more reactions from you. Take for example the Passive Loop Antenna project. Superficially, this is a very simple device and you would be justified in thinking that it wouldn't do much. We reacted exactly the same way at first. I mean, it's just too simple, isn't it? But if you have an AM broadcast radio with its own loopstick antenna and you're having trouble picking up a weak station, this device works like magic. The increase in signal when the Loop is placed near the radio and tuned for maximum pickup is amazing. It's just the thing if you are staying in a caravan. Anyway, I'll not say anymore; you can read about it for yourself. The second project that we are very pleased with is the Touch-Lamp Dimmer. It uses just a single new IC from Siemens and a Triac to provide a dimmer which can be turned on and off or dimmed at a touch. It can also be programmed to provide either a "soft start" switch on or to store the selected brightness of the lamp so that when you switch on next time the lamp will be set to the same level. This is pretty fancy stuff and makes the ordinary knob type dimmer look pretty passe. Well what do you think of projects like these? We know that some readers do not buy an issue unless there is something in it that is of specific interest at the time. Later on they often regret not buying the issue because they have missed out on an article which is now vital. If you don't buy SILICON CHIP every month, we'd like to know why and what we have to do to make you a convert. Why not drop us a line? Leo Simpson
