USB Powered DSO138 Oscilloscope Case

thingiverse

This is a custom-made version of the DSO138 oscilloscope case, engineered to eliminate the 9V power port and utilize USB power instead. This modification transforms the oscilloscope into an ultra-portable device that can be powered by a USB power bank. To achieve this feat, I acquired a MT3608 voltage step-up circuit board to elevate the 5V power from the USB to 9V, then soldered the input and output cables to their designated pins on the DSO138 oscilloscope (see picture for the USB power connection). The 9V socket and white 2-pin socket were removed from the DSO138 circuit board to accommodate the MT3608. Since the MT3608 protrudes slightly from the top edge, a bit higher than the LCD screen of the DSO138 board, I designed the case specifically to make room for it. It's worth noting that I discovered the new version of the MT3608 is not as tall as the older model but significantly longer. Consequently, I made a small adjustment to my original design for the front cover, although I have yet to test this modification. You can download the appropriate STL file tailored to your requirements. Furthermore, I applied masking tape under the MT3608 to serve as an insulator and separate the two circuit boards. The case features three clamps that securely hold the top and bottom together. This design allows me to swiftly remove the clips, open the case, and gain access to the oscilloscope's internal components. Additionally, if you're not satisfied with the stands I created, you can always craft ones that suit your needs. The dimensions are clearly illustrated in the picture, and the case thickness is 0.92 inches (all measurements are in inches).
