Arduino Digital Caliper Readout with Bluetooth Case for PCB

This is a housing for the LimiDIY board, with which a digital readout can be set up with an Arduino Pro Mini. This also has a Bluetooth function. Digital calipers, e.g. from China, are used as measuring rulers, which send a 24-bit signal.

The required PCBs can be produced very inexpensively in China (http://www.jlcpcb.com/ ... very good products and fast processing !!).

This thing is just the case I designed for it.

You have to print: - 1 x Front 1 - 1 x Front 2 - 1 x Back - 2 x Hinge - 1 x Hinge_2 - 4 x Spacer_12mm

Screws for case needed:

... x DIN912 M3 x ... Screws (will be added) ... x DIN912 M3 x ... Screws (will be added) 8 x ISO 7380 4-40x3/8" for the D-Sub connectors

At this point, thanks again to LimiDIY for the great project! Works great and was fun to build.

If you are interested, I will be happy to provide you with a component list, also for the entire project online if you wish.

Do not hesitate to contact me if you have any questions.

I am not connected to LimiDIY or to jlcpcb.com these are just positive experiences with which I was able to realize this project.

The current project is for a conventional lathe (axes X, Z2 and Z). I am happy to upload a housing for a milling machine (X, Y, Z) on request.
