Its really nice to have the pinball cab already in place, I will be painting over those tutles soon, even though I feel like im sinning! But what a better way to bring an old pinball to life than reincarnating it into a homemade pinball!!

The artwork changed a bit, here is the actual print!

I really wanted this pinball to stand out among the rest. This is why I not only have a pinball DMD (well kinda) display, but thought an old school point counter system would be retro and cool! So my mission was to include a basketball scoreboard into the back glass artwork, and I must say it came out better than I expected. I built the whole thing out of LEDs and Shift Registers basically. As you can see in the pictures below, there are a few different “modules”. They all connect together over ribbon cable, which includes the latch, clock and data for the shift registers, plus a couple of grounds, +5v and +12v. The Arduino Mega is what is controlling all of these along with sending signals for the other arduinos that take care of the other functions, like audio and the DMD (check out my other posts for details on those).

Alot of mess, but it does all make sense. These are for the scoring system of the scoreboard. These are essentially 7-segment LED Displays made out of 10mm orange LEDs.  Its hard to see, but each board has a 10-pin IN and OUT ribbon cable connection to run the shift registers, ground and power. I then needed to create the Period, Possession, Overtime and shotclock LEDs. Which is below.

Again, the shotclock is basically 7 segment LEDs, but this one out of 5mm Red LEDs. Then the est are more 10mm Orange LEDs, the 4 shift registers power all of these. Some may say you could get away using less shift registers since there are unused pins (especially on the third digit of the player scores) but they are cheap enough, that using them like this made it much easier to program and looks cleaner. This board again has the 10-pin IN and OUT on the back to link with the player scores.

Next I needed to recreate the backlight wood door. I like using actual bulbs instead of a fluorescent light or LEDs becuase it gives it a more retro, real pinball feel.

These lights are controlled by a lighting board, that uses shift registers and mosfets. This board gets its commands over I2C so it can work while the other things are going on. You can see this board in the pictures of the inside, and it will be upgraded with much more MOSFETs and transistors soon. So after installing this, and getting all of the LEDs aligned with the artwork, it looked like this.

Looks great to me! To really see it in action, check out the video at the top of the page!

Here is also a glance at the inside. After I finish getting it all organized and finished, I will do another post, with more details.
