Chris decided to enter another project into the Open 7400 Logic Competition. The beeping down counter, as it’s name suggests, is a pre-settable timer which beeps and uses a display to show the seconds left on the timer.
The goal of this project is to duplicate the down counting circuit used by the character Ivan Vanko in Iron Man 2 to aid his escape from prison in Manaco. There are three key components that go into this design:
- A Down Counter With Dual 7 Segment LEDs
- A Push Button To Initiate The Down Counting
- A Quick ‘Beep’ Sound With Each Down Count
Via the contact form.
He also filmed a video of his project which is shown below.
