DSO112A Chassis to hold 18650 Batteries

Last crawled date: 4 years, 3 months ago

The long awaited chassis for the DSO112a pocket oscilloscope with kickstand and battery holder.
The scope originally comes with a 1120mAh battery, but I got tired of it running out of battery so this chassis holds TWO 18650 batteries.
Yes it is bulkier but its designed to be held in two hands and sit with a slight incline on your desk. Also sits up-right. Also has a kick-stand which kind of sucks at this point but it works. Be weary of support material on that though.
It comes with an internal spring plate which sits over the mount holes, such that when you push on the screen the force is delivered evenly through the back of the chassis. You got no idea how hard it was to get this right.
Use 0.05mm resolution on the stand-offs if you can - at least where they interface with each other.
Use 0.05mm resolution on the roof (the sloping back) if possible to remove stair-step effect.
Use 0.05mm resolution on the button. The tolerance here is important.
UPDATE:
New version keeps display tight, fixes tolerances of kickstand and button.
PARTS NEEDED:
Requires four square M3 size nuts, and some M3 screws. At least 8mm screws needed, but it has tolerance for longer.
Requires 18650 battery clips and that can be found on aliexpress.

A good set of M3 screws & nuts (use the 8mm guys):https://www.aliexpress.com/item/32802231194.html
I recommend putting the battery springs up the top as to keep the center of gravity lower.
