Case for DSO138 digital oscilloscope

thingiverse

Note: It appears there might be a new edition of the PCB before attempting this design, please also look at this modified version: http://www.thingiverse.com/thing:1202909 This is a case for the DSO138 digital oscilloscope. The single-channel 200kHz bandwidth 1Ms/s oscilloscope is very straightforward, and its primary intention is as a learning tool. However, I think it may be useful in various applications due to its simplicity, making it suitable even as a portable field oscilloscope. I have created this case for enabling fully portable, battery-powered usage that the original design did not support. The battery version necessitates an SPDT toggle switch and a 9V battery clip; wiring should follow the provided diagram. A hoop safeguards the switch from being turned on inadvertently. A variant of the case without batteries is also available. The oscilloscope is offered as a kit at http://www.jyetech.com/Products/LcdScope/e138.php, as well as at Banggood http://www.banggood.com/DIY-Digital-Oscilloscope-Kit-Electronic-Learning-Kit-p-969762.html. To assemble the oscilloscope case, you'll need three button1 units and two slider1 components, one button2 unit, and another slider2 (upper position). Slider buttons may require internal cleaning; refrain from applying force when placing them over the PCB switch slider arms. Consider adding labels to the switches, but it might not be necessary as the display reflects the settings. For an optimal effect, the LED should be mounted so that its height matches the LCD (see picture). Printing Guidelines: The case should print without support and with minimal cleanup. If warping becomes a concern, consider applying a brim to your design. The top section must be printed upside-down.
