Spacecontrol/Baikonur

The big space control

Goals

• Lights can be switched using a web interface and regular light switches.
• Roofs can be opened and closed.
• Redundant: if the Arduino fails, the light switches remain working.

Hardware

What we have available

• A little under 100 industrial relays (Piet)
• Industrial electricity cabinet (Piet)
• Diodes and NPN heavy-duty switching transistors. (Koen)
• Cover for the big electrical cabinet (jaroslav)

Thanks to all who have contributed hardware!

What we need

• More electrical cable

Wiring color codes

Lesson learned: adding new colors on the fly will result in chaos:

Color	Function	Notes
Brow	220VAC L1
Grey	220VAC L1	switched for outputs
White	220VAC N
Blue	+24VDC	except immediately at main 220VAC input
Red	+5VDC	for Arduino inputs
Black	Ground	light switches switch ground
UTP cable	I/O for Arduino

INPUT UTP cable

It's the one with the YELLOW tape!
This cable feeds signals from the Arduino to the relays .1

Pin #	Color	Function	Notes
1	Green	Relay 01 input
2	Green / White	Relay 11 input
3	Orange	Relay 21 input
4	Orange / White	Relay 31 input
5	Blue	Relay 41 input
6	Blue / White	Relay 51 input
7	Brown	Relay 61 input
8	Brown / White	Relay 71 input

OUTPUT UTP cable

It's the one with the RED tape!
This cable gives the Arduino feedback about the state of the relays .0

Pin #	Color	Function	Notes
1	Green	Relay 00 output
2	Green / White	Relay 10 output
3	Orange	Relay 20 output
4	Orange / White	none	Will be connected to R30 input with resistor
5	Blue	Relay 40 output
6	Blue / White	Relay 50 output
7	Brown	Relay 60 output
8	Brown / White	Relay 70 output

Power UTP cable

Pin #	Color	Function	Notes
1	Green	Ground
2	Green / White	Ground
3	Orange	Ground
4	Orange / White	Ground
5	Blue	Ground
6	Blue / White	Ground
7	Brown	+5VDC
8	Brown / White	+5VDC

Software

The software is identical to the one in the small Spacecontrol.
