Object: Create a safe box for home made appliances.
Requirement 1: a fireproof box that will alarm if there is a fire inside
Requirement 2: Soundproof a nosey appliance
e.g. a safe place to keep a mains power, china box I don't trust.
Requirement 3: monitor materials, e.g. keep an eye on spool size, or measure as it leaves, or by weight,
Requirement 4: trending of data with intelligent alerts
This is over kill. Just to be clear.
Design Solution:
A fireproof box that will warn when there is a fire,
Box is also sound proof,
Box will monitor key components of appliance in box,
Solution:
RPi & Arduino:
Camera
Smoke detector
Temperature & Humidity (?)
3D printer monitor; interface via octoprint:
Thermocouple (TC) on power terminals; single point of failure
TC on motors (~5)
TC on Bed
TC on extruder
Monitor Filament status (small spring on a flap attached to a resistor)
Monitoring:
1: Emergency (smoke or hot power terminal)
Alarm & Email & SMS & Kill Power
2: Error (print stop, filament out,
Beep & Email & SMS
3: Warning (Filament low, power surge, print finished,
Beep & Email & SMS
4: Information (status,
Data:
Temp & humidity
Spool status
Temp of motors, extruder, power terminals,
Elec data, volts, amp, watt,
Technically the camera should know what the elevation of a print will be at a given point in time therefore Opencv should be able to say if a print is going to plan or not.
Box:
A box, ideally metal something like a filing cabinet (saw that somewhere can't find it now)
Fiberglass insulation (fire and sound proof ish)
Vent, not sure about this,
3D printer sitting on slides
All elec on control box on top of box, not part of printer
Single power supply, split between control box and appliance, control box can kill power to
Separate box for filament or
android tablet for interface, via web interface, allow remote monitoring
