First pic don't work, but yes ofcourse you should stick to the components in schematics. There's a big difference in normal and electrolytic caps.

I think you need to use the eletrolytic cap.

At first I used a normal ceramic cap and had some problems (the display worked tho). I then replaced the cap with a small smd cap (not electrolytic) from a junk pc motherboard and now it works just fine.
