DS0138 Digital Oscilloscope Case

thingiverse

This is a casement I designed specifically for the DS0138 digital oscilloscope. It's a budget-friendly one channel O-Scope that comes with just a circuit board and leads, leaving out all other accessories. This case gives it a sleek appearance while providing some level of protection. The original board features an exposed LCD screen, with buttons and switches mounted on the main board, resulting in them being recessed from the front face. I opted for a flat case design, so there are caps printed out that slide on top of the buttons/switches. A fair warning: they can be challenging to install. To make it easier, I used petroleum jelly (I actually employed Burt's Bees hand cream, but you can use anything with some tackiness to hold the buttons and switches in place for a bit as you put the top case on.) Then, using a small screwdriver, I moved the switches and buttons into position from the top face of the case. Once the board is seated inside the top case, the buttons and switches function well and don't rattle around. On my current setup, I didn't secure the bottom portion in place. It's more like an interference fit for now. However, I designed it to be glued together, so if you prefer using super glue, the case should fit snugly and never come apart. There are two top cases available - one with a slot for the DC barrel plug and another with the DC barrel plug hole plus an additional hole next to it to allow wires to be plugged onto the power inlet of the board. The types of wires this design accommodates are colorful jumper wires featuring rectangular black ends (similar to: https://www.kitronik.co.uk/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/c/4/c4128_large_jumper_wires_20cm_m-f_pack_10.jpg). You can, however, use any wire you prefer. This feature allows for the use of an external power supply that doesn't come with a barrel connector. In the future, I might revisit and edit the bottom part to include a stand, enabling easy viewing while measuring stuff. Alternatively, it could be designed to mount two cases in tandem, creating "two-channels". Here's a little video showcasing the casement and how it looks: (Note: The back of the case isn't secured properly, so I accidentally flexed the case and was holding down a button. When the back is securely attached, the case doesn't flex and this issue resolves itself): https://www.youtube.com/watch?v=ggS3I4GBoy0
