This is why I open all power supplies before using them if at all possible.
Mounting this supply would have put the housing at mains voltage. That’s also why you should never forget the protective earth connection.
Jscut is an open source browser based GCODE generator that uses SVG as an input.
Jscut seems to be the predecessor of LaserWeb by the same developer and several other contributors that is focused on controlling lasercutters but does basically the same with a more polished interface.
UV4L was originally conceived as a modular collection of Video4Linux2-compliant, cross-platform, user space drivers for real or virtual video input and output devices (with absolutely no external difference from kernel drivers), and other pluggable back-ends or front-ends.
It has evolved over the years and now includes a full-featured Streaming Server component with a customisable web UI providing a set of standard, modern and unique solutions for encrypted live bidirectional data, audio and video streaming, mirroring or conferencing over the web and for the IoT . Since recent releases UV4L has also been providing a RESTful API for the developers who want to implement their custom applications.
The Video4Linux2 uv4l-raspicam driver for Raspberry Pi has been extended to support the TC358743HDMI to MIPI converter chip. This chipset is often found in the B101 capture boards made by Auvidea.
This projects uses a interesting DIY approach to broadcast video via wifi. Video transmitter and receiver are never directly associated. The receiver is put into monitor mode. This results in a transmission that behaves more like a analog solution. With a weaker signal there is not an immediate disruption of the transmission but a degradation because of packet loss.
First, if you haven’t already, activate the camera in raspi-config. Login via SSH type “sudo raspi-config” select “Interfacing Options” and enable the camera.
Configuring the camera
Now edit “sudo nano /boot/octopi.txt” uncomment the camera=”auto” line and change it to camera=”raspi”. Uncomment camera_raspi_options=”-fps 10″. These settings configure the camera to provide and image in the format 640×480@10fps. If you would like to change that check the available options at: https://github.com/foosel/OctoPrint/wiki/MJPG-Streamer-configuration
Enabling the camera in the octoprint browser interface
In the browser click on the little wrench in the top bar to open the settings dialog. Select “Webcam & Timelapse”. Set the “Stream URL” parameter to “http://octopi.local:8080/?action=stream”. Obviously change the hostname if you have configured it to something different.
Finally restart octoprint for the changes to take effect.
