while looking for cached pages for something unrelated to Audis for once I decided to see what was on there from this forum before I was done searching.

wow -- flashback to my midnight mod'ing days of swaping K03 turbos and going stage 3.

I never said I had any problems with it....

Mr. Head

On my senior design project...

My first thought was an LED matrix, but it seems there are either too many wires or too many components there. Plus, that seems a little easy for a senior project.

I'm going to bring that up to audi junkie and the family on turkey day. lol

Mr. Head

It was a project for a defense contractor. They use a little device called a bridgehead to ignite shock tube to initiate an explosive device (detinator). It helps to separate the detinator from the initiator.

Here is what they had, that no longer was functional.

This tester was used to repeatedly ignite the bridgeheads upwards of 100 times. Their quality department determined that if the Bridgeheads fired 100 times without a failure, then they will always fire.

Their production required them to test the bridgeheads one at a time. It was to the point that they had 15 employees testing these bridgeheads every day along with trying to do normal work...

We had to design the Arm/charge/fire circuitry, a way to read the test result (pass/fail), program the microprocessor to control the Arm/charge/fire/result. We also created a GUI to recieve the result data and populate an excel file to match the result of the test to a specific serial number for their quality department to track the pass/fail data.

The front of the tester consited of power posts and led's to display the pass/fail of each tester circuit. On the left there was also a Key Lock out switch, on/off switch, and control buttons.

All of the circuit boards were produced through Orcad layout editor, sent out to be spun up, and consited of all surface mount components that we soldered by hand. We were able to prove out the functionality of the boards within 2 revisions. Each board consited of 4 Arm/charge/fire circuits with 7 boards total. We also designed the microcontroller board, and I programmed the processor.

All-in-all, this was one of the most professional and functional Senior Design projects completed in the last 10 years of our college. And the company actually uses it for production.

This was the final product:
