As we can see, oscilloscope has a rarely high accuracy, which is unlike multimeter, but allowing us to see the processes in the dynamics. Earlier oscilloscopes consisted of vacuum-tube which then replaced by the transistor, but the result is still displayed on the CRT screen. Eventually, they were replaced by the digital counterparts, smaller, lighter and more convenient. However, have you ever tried to develop a homemade oscilloscope by yourselves?
The collecting is certainly easy and even a schoolboy can done it on his own hands. The most important thing you have to do is choosing a decent DIY Digital Oscilloscope Kit. In this article, I would like to recommend the JYE Tech DS0150, of which features are as following.
- DSO Shell has similar bandwidth as DSO138 though it contains significant improvements in structure, mechanical, and operation.
- Display and MCU are now mounted on the same board (mainboard), avoiding using inter-board pin-headers. Users’ feedback from DSO138 has shown that soldering on the pin-headers is often problematic for many beginners. Analog channel is placed on a separated board which contains most user install parts. This brings in better separation between analog and digital circuits. Without the analog portion the mainboard is actually a general purpose control board that can be used in many other applications. The mainboard is fully installed (except a few through-hold components) and factory tested before packing.
- This DIY Digital Oscilloscope Kit comes with full enclosure. The front panel and top/bottom brackets are flexible for easy user modification.
- Rotary encoder has been added. It makes parameter adjustment much quicker and easier.
- The sensitivity of DSO Shell has been extended in both directions and is higher and wider than DSO138. It reaches 5mV/div — 20V/div while DSO138 is only 10mV/div — 5V/div.
- DSO Shell runs on 9V power supply. Users need to prepare their own power supply since it is not included in the kits. The power jack on the mainboard is 5.5mm/2.1mm DC plug. Alternative 2-pin connector (0.1″ pitch) is also provided for convenience to connect to different power sources.
