This saves the hassle of trying to manually mess about with knobs and instead will move the telescope to precise positions at the press of a button. It has a set of motors that, when requested by a hand controller, will ‘slew’ to any object in the sky. This telescope, in particular, is a GoTo model.
This project started a couple of months back when we found a cheap telescope on Gumtree (for our overseas readers, an Australian website for second-hand goods) for a modest $200. Reverse engineering, tinkering, hacking, whatever you want to call it – the process of modifying something that isn’t exactly how you want it is one of the benefits of learning electronics! While designing and assembling projects from scratch is usually what we do at DIYODE, some find it more fun to improve existing products. In the age where DIY electronic parts are cheaper than ever, it’s no surprise that makers are finding more creative ways to add more features and convenience to their favourite household gadgets.
