Since there is still a little bit of time to submit another entry to the 7400 competition over at dangerous prototypes, I thought it would be interesting to give some insight on how to build the circuit from a signature movie prop in the film Iron Man 2 - a beeping down counter.
(My Version Uses Play-Dough!)
Purpose & Overview of this project
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
There are two unique challenges present in building this device. The first is that I have no idea what the authentic device would look like-only what I saw in Iron Man 2, so I'm building a unique design for how I would make the movie prop circuit with logic devices. The second is that I want the entire project to fit on a single breadboard, which limits how much functionality I can pack into the project.
