 New technology has built popular oscilloscopes from a kit. It is a very inexpensive way to get a good gauge, but the low price way up to high proficiency. A small Chinese kit has attracted attention among the world's electronics enthusiasts. For 300 crowns and a couple of evenings work gives it a fully functional digital oscilloscope. It is not a simple construction, but given that a fickoscilloskop for professionals can cost 15 000 SEK and up, seem few hours of soldering as a good compromise. The target audience is hemmapysslare and students. Oscilloscope has been rather modest specifications, and focuses on digital electronics: robots, programmable logic and the like. For analog circuits, such as hi-fi construction, it can be a complement to a regular millimeter, but not enough in all situations. The construction is not suitable for beginners. Some components, such as processor and crystal circuit, are forlodda. The rest builder assembles self. It's about soldering surface mounted circuits, in some cases the resistance down to a millimeter in length. Soldering iron with controllable temperature and narrow tip, magnifying glass and sharp forceps is necessary. The documentation is adequate, but economical. It needed a high attention and some of his reflection in order not to confuse it. Many wonder what to secure with an oscilloscope to, and why, if so, will build a self? These are both useful and fun. This kit costs a quarter of the cheapest machines in stores. By measuring enough yet for hobby use, That this particular specimen is small enough to go into the pocket is another advantage. My Tektronix 2235 on the workbench weighs 6.2 kilograms. Jyetech-construction weighs just 70 grams. Yet I admit willingly that the rational arguments are not sufficient. The main reward is the warm feeling when the unit starts for the first time, and an elegant waveform is emerging on the LCD screen. |
