CD4001 LED flasher circuit help

[Jimitrader]

Hello i am experimenting with Cd4001 quad nor gate (fancy LED flasher) from my radio shack digital projects workbook 2.

1. Is it possible to use the other side of the 4001? as i am only using 1-7 and pin 14 for power?
2. why would the leds blink once while turning pot when power is off? is there a way to stop that from happening? I am going to add a ping file showing the design.

Draw a pencil sketch circuit diagram and include any power supply you are using.
These "fritzing type" displays are next to useless.

Agreed. For one thing, not all breadboards have the same internal connections, e.g. contact grouping for the supply rails.

Is it possible to use the other side of the 4001?

Definitely.
What's more: If you don't use the other gates, tie the open inputs to GND or V_CC. It doesn't matter which one. Open CMOS inputs (also called floating inputs) can cause the gates to oscillate or do other weird stuff, drawing high currents and may in turn possibly lead to the destruction of the gates or the whole chip.

why would the leds blink once while turning pot when power is off?

Obviously power is not completely off. At least the LED strips must have power, else no blinking can occur. For a more detailed analysis a true schematic is needed, see the preceding posts.
