Vention Mini HDMI Splitter Sonoff Shell

Specs:

• 2mm diameter for screw holes the sonoff goes in
• Made for Sonoff 5V Relay Module
• Included gcode is for Ender 3 (ready to print)

Todo 3D-Part before Print:

• Lay flat on bed in Cura
• Rotate body, so the inner lines are parallel to bed edges (See in print-ready [Ender 3] gcode i included in the files)
• Infill 40% is recommended

Todo Sonoff before Assembly:

• Modify/configure your Sonoff SV to operate in so called "isolated mode", picture shown in its wiki page: https://www.itead.cc/wiki/Sonoff_SV
• The picture doesnt describe all you have to do tough, so look for at least one more youtube video on how to configure isolated mode.

To sum it up, you have to

1. Remove the 2 Resistors shown in the last wiki-picture
2. Solder or however connect the input + and - poles
3. connect your 5v + and - you will use to power your sonoff to the breakout pins right next to input holes you soldered/connected together

Additional Steps in Vention to get it all working
4. Drill some holes, so your cables will fit trough them to make a bridge for the cables between vention PCB and Sonoff PCB (like in the picture in "Post Printing") and get the cables trough
5. Solder your Vention input (the pins in Vention splitter, which are connected to the power source) to your sonoff input (remember, breakout pins) and dont forget the polarity
6. short-circuit the button-pins in the middle of the vention pcb to see which 2 solder-points of the button connected to each other will simulate a button press with e.g. metallic tweezers
7. having found a combination that leads to a button press, solder these to points each to the sonoff output cables (polarity doesnt matter here)
8. screw the vention splitter together and place it onto the case, done.
