Bulbs Vs LEDs Which is Best? YOU decide!

I talk a lot about LEDs and their pros/cons (mostly pros in my book) but obviously this is a heated discussion among enthusiasts. I decided to try an experiment and do different configurations of stock incandescent bulbs, along with a warm white and cool white LEDs and even a mixture. Can you tell the difference? What do you think looks best?

Before I show you a video of the process, here are random pictures of the backglass of Paragon with different lighting configurations. If you don’t want to know which is which, don’t scroll down too far…

Ok, below is the same experiment done on video.. and if you scroll down farther, you will see the lighting configurations revealed… NOTE that the order of the light configuration in the video is not in the same sequence as the A, B, C pictures. I mixed them up for the pictures so people could try and guess first without knowing.

What do YOU think? You can also leave comments on Youtube here: https://youtu.be/Rjl4fi7t8I4

How to properly clean battery damage off a MPU board

This is the next video in my series of work on Paragon. After the first look (http://pinballhelp.com/first-look-bally-paragon-pinball/) I discovered there were still issues with the MPU board that were the result of continued corrosion even after the battery was removed and the board was supposedly cleaned. Whoever did the previous work didn’t clean the board enough and corrosion continued. I’m going to do my best to salvage the board.

Quick demo of fully-modded Stern “Trident” pinball with new rules and sound

After getting my Trident operational, I installed the BSOS system and have been working on fine-tuning the custom code and sounds. Here’s a short demo of what the new Arduino-based controller does to a standard Bally 18/35/Stern early solid state game.

Resources (courtesy Dick Hamill):

The code is all available on GitHub. It’s broken down into a base library and then machine-specific implementations. Rewriting other games requires a moderate knowledge of C/C++.

Here’s a suggested parts list. If you bought all these things, you could create 6 of these boards. If you don’t need that many boards, you might find cheaper ways to source smaller quantities. I haven’t done any work to figure out if this is the cheapest way to source any of this stuff.

Cheap Arduino knockoff x6 ($20.99) – needs CH340 driver for programming / has to be ATmega328P

0.1″ 40-pin connector (40 pieces for $7.99)

32-pin Prototype PCB (2 pack for $9.99) – this won’t work for Alltek or MPU-200 because they have a 34-pin connector

Wire ($7.99) – tons of wire

Boot switch – x2 ($8.99) this switch will work for activating the Arduino board and toggling the speaker (see the writeup here to find out why: https://ballysternos.github.io/install.html)

How to make a test bench rig for Bally-18/35 MPU boards using a PC power supply

I found this old video the other day and realized I didn’t have a post on my main site showcasing this video so I wanted to add it (also, this was before I learned the proper pronunciation of “Bally” LOL…. bah-lee).

How to add a switched power outlet to your pinball machine

These days modding games is all the rage: adding fancy toppers, custom lighting, subwoofers and powered speakers and more. But many pinball machines don’t have a facility for you to plug in extra stuff in your game. Many games do have a “service outlet” inside the game, but this is what’s called “un-switched” meaning it’s on all the time – mainly so technicians can use a soldering iron on the game with the power off. In this video I go over the process to tap into the switched power lines of the game to add your own extra outlet(s) that come on when you turn the game on.

Fixing / Rebuilding Stuck Pinball Flippers on Early Ball/Stern Solid State Games

This is a short video going over the steps to repair/rebuilt/refurbish early solid state pinball flipper assemblies, such as those on Stern and Bally games (but this also basically applies to most pinball machines). I go over the process specifically on a Stern Trident and show the specific style of plunger and assembly they’re using, but most games use similar parts. You can use these techniques to rebuild/refurbish pinball flippers on most games.

Also, there’s another thing I don’t cover on the video that may also be a cause for stuck/sticky flippers, and that’s crud around the flipper button. Sometimes the flipper button assembly can be dirty and the button may stick – that can also cause the flippers to not behave properly, so be sure to check and clean the flipper button regularly too!
