This will allow the use of 2 vending machines to dispense your Ingot and Ore needs to your manufacturing area. I highly suggest stacking your Ores and Ingots in your sorting facility to stacks of 50 for each type.
You will simply turn a dial, see your selection, and press a button to get it delivered from your vending machines. No more searching. As long as you have it in your vending machine, it will come.
You will need the following for this complete IC collection Build.
2 x Vending Machines ( 1 for ores, 1 for ingot)
1 x flashing light
2 x Dials ( 1 for ingot selection, 1 for Ore selection)
1 x Console
1 x Circuit Board Hash Display for the console
2 x Diode Slides
7 x Signs The signs will be as follows:
Ore Dial Setting:
0=Nothing, 1=Coal, 2=Copper, 3=Gold, 4=Iron, 5=Lead, 6=Nickel, 7=Silicon, 8=Silver
Ingot Dial Setting:
0=Nothing, 1=Constantan, 2=Copper, 3=Electrum, 4=Gold, 5=Invar, 6=Iron, 7=Lead, 8=Nickel, 9=Silicon, 10=Silver, 11=Solder, 12=Steel

Now if you happen to forget and 2 dials selected, thats what the flashing light is for to warn you of having 2 dials selected at the same time.

This build does require that you have some kind of sorting or your ores and ingots, and stacking. I use a full fledged sorting facility.
