I would add that the 7 segment display has to be a common anode display and current limiting resistors need to be connected between the segment outputs of the 7447 and the segments of the the display. The value of the resistors depends on the Vf of the individual segments and the brightness of the displays.

Get a 5V+ first. Run an A-Stanle through a NE555 timer, then connect it up to the 74LS90, then to 74LS47, then finally to the 7 Segment. You will need to ov downloaded the datasheets for each IC to see the pinouts, etc. Requires minimum IC Logic Knowledge.
