3D printed battery cover for Hewlett-Packard 100LX/200LX
One of the most typical hardware failure of HP 100lx/200lx is a broken battery cover latch. That’s why a spare 3D printed battery cover would be a good option even if your current battery cover is intact. A free 3D model of the battery cover is available on Thingiverse. However, I was not satisfied with the quality of this model, therefore I’m glad to present you a custom (improved) version.
You can download this model for 3D printing here: HP 100LX battery cover.stl.
Testing the plotting function of HP 100lx
Plotting the function f(x)=1/sin(1/x) is a very difficult task. Few graph plotters are able to draw the function correctly.
Unfortunately, the built-in graph drawing program in the HP 100lx also does not quite cope with this task. Obviously, the specified function never takes values in the range (-1; 1).

This Hewlett-Packard HP 100LX is still used on a daily basis
I met the owner of this device few days ago. The guy told me that he repaired this device by himself, and now uses it for programming microcontrollers. He writes programs in C and Pascal. The main advantages he mentioned were small size and extremely long battery life.
