Some tips:
1. Since making blocks uses 3 ores, you can reduce this number by compounding. You can compound Tin Ore + Tin Ore to get Tin Material, Tin Block or Tin Sand. Same goes to Copper and Aluminum Ores.
2. To save Aluminum Ores for making Hard Aluminum Plate you can compound Aluminum Ore + Granite. This way you can also get Aluminum Block, Plate or Sand.
3. Getting Crude Oil is very easy if you have Centrifuge. Combine 2 Coconuts in the centrifuge to get Coconut Oil then keep recycling whatever you get till you get Crude Oil.
4. You can also get Electronic Wire, Capacitance and Resistance from Universal Island for 30g.  To go to Universal Island take Boat to Oslya from the very top of the North Island. Then go to Universal and try to leave Oslya from the West beach. And if you face monsters which you can't battle just log out then back in and you'll escape the fight.

P.S. Numbers means how many pieces you must have, not how many times you need to click (example Firewood).


II. Ok, I got it, how is works?

The Desktop Computer does not manufacture 5 items at same time, it only manufacture 5 items one by one without pressing any buttons. Also, you can only make one item of the same group (example just one Charcoal) and you must have all needed items in your inventory.
How to start:
1. Start manufacture item, as it is started press somewhere on the ground and press Confirm.
