Input mux
About the Input mux PCB
Input mux is an open source PCB design by HacklabJKL, published on GitHub. It is a 2-layer board measuring 89 × 45 mm, with 45 components from 9 distinct parts.
Other key parts include the 74HCT151D. By type, the board carries 34 resistors, 4 capacitors, 3 ICs, 3 connectors and 1 diode.
It belongs with the robotics & motion designs in this gallery.
From the project
Second version of Hacklab's custom built CNC machine
Sergei 2 CNC machine project ============================
This repository contains design files for Hacklab Jyväskylä's CNC machine project. The machine is built out of existing linear assemblies that have been donated to us, and as such it is not readily reproducible. But some of the modules may be useful and in any case this repository contains information for future maintenance of the machine.
