ambadran/PCB-Manufacturer
A CNC machine with a kinematic mounting mechanism and customized GRBL Firmware to allow automated end-effector change; Allowing access to all the tools needed to create a PCB without human intervention.

This Project is a real-life simulation of a traffic camera monitoring for speed, traffic light passing and other violations. Incorporating IOT with a Web App hosting to monitor and control everything.
Traffic simulator is an open-source printed circuit board by ambadran, from the ambadran/traffic-simulator repository on GitHub. It is a 2-layer board of 64.5 × 50.3 mm with 23 parts on 25 nets, routed with 162 tracks and 0 vias.
It is built around the L7805 and S8050. Its parts include 10 resistors, 3 diodes, 1 capacitor, 1 IC and 1 transistor. It belongs with the home automation and IoT boards of this library.

It measures 64.5 × 50.3 mm and has 2 copper layers, 1.6 mm thick.
23 parts, built around the L7805 and S8050. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the ambadran/traffic-simulator repository on GitHub, at the commit this page was made from: the board is Circuit/Circuit.kicad_pcb and its schematic Circuit/Circuit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask ambadran before reusing the design.
