Sean Irby discusses building 8 Ball Beyond, a reliable homebrew pinball machine using modern frameworks and off-the-shelf components.
8 Ball Beyond has been running reliably on location at Adaball arcade in Seattle for extended periods (summer, then after Expo through ongoing operation), requiring only standard maintenance
high confidence · Alan and Sean discussing 8 Ball Beyond's location deployment
8 Ball Beyond experienced one audio system crash per day due to a potential code bug, but otherwise remained stable on location with minimal intervention required
high confidence · Sean directly describing the audio issue and operational reliability
Building a single homebrew pinball machine costs comparable to or exceeds the cost of a new Stern Pro machine
high confidence · Sean noting he couldn't track costs after 5 months, Alan estimating Stern Pro ballpark, reference to Led Zeppelin homebrew presenter saying it costs more than Stern Pro
Mission Pinball Framework allows game rules to be written in configuration files rather than line-by-line code, with complex features like multiball requiring only six lines of configuration
high confidence · Sean explaining MPF's approach to game logic
Sean's custom-molded resin ball targets have held up well on location but yellowed after 6 months due to UV exposure from window light
high confidence · Sean discussing durability of his resin cast components
Modern boutique pinball manufacturers experience higher reliability issues than Stern due to scale differences, software problems, and bill-of-materials cost-cutting not present in single homebrew builds
medium confidence · Alan's theory about software load management and manufacturing at scale; Sean's commentary on hardware quality
Sean's electrical engineering background provided confidence but minimal practical help for woodworking and mechanical design aspects of the project
high confidence · Sean explaining his background and lack of shop class experience
8 Ball Beyond uses Multimorphic P3 Rock boards and runs on Mission Pinball Framework, not Fast boards
“The whole concept with it was to make a new 8-ball game that paid homage to all the three prior ones that Bally made in the 70s and 80s. So it includes a shot that is similar to one of each of those games.”
Sean Irby @ early in episode — Explains 8 Ball Beyond's core design philosophy and connection to classic pinball heritage
“I didn't think about the theme at all. I just thought I would make a cool play field and then bolt the theme onto it later. And that was a bad way to start, not having a plan, basically.”
Sean Irby @ mid-episode — Reflects on his first failed homebrew attempt and lesson learned about starting with a strong concept
“I definitely wanted it to be code complete before I let anyone play it... Once I saw that and started thinking about ways that I could include some more features that took up that back part of the play field, I started running with all these different ideas.”
Sean Irby @ mid-episode — Shows his commitment to completeness and iterative design refinement based on physical cabinet space
“Having played quite a few homebrews at shows now... to learn that like this thing's actually just been living like I said in the wild like a pinball machine should, it's very impressive.”
Alex the Waterboy @ late-mid episode — Highlights how unusual and noteworthy 8 Ball Beyond's reliability is compared to other homebrews
“You can count on that. [about the audio crash happening once a day]... If it crashes, they just go reset it kind of thing? Yeah. Yeah. It's the only thing different is you got to wait about about like 20 seconds after you turn it off to wait for the laptop to shut down gracefully.”
Sean Irby @ mid-late episode — Demonstrates the minimal operational impact of the known software issue and practical workaround
“Most fun part? Anything having to do with modeling... I spent about a month or two kind of spending a few hours every day learning Fusion 360... it was almost like my own kind of like making my own like project management tool while doing it.”
Sean Irby @ late episode — Reveals the most rewarding aspect of the build and unexpected creative benefit of CAD modeling
design_innovation: 8 Ball Beyond demonstrates exceptional reliability for a homebrew machine through deliberate component selection (high-quality off-the-shelf boards, professional-grade parts from Fast/Multimorphic/M-Ball Life/Marco), conservative mechanical design (single-level layout, no complex ramps), and thorough testing cycles (3 years of personal play before location deployment).
high · Sean's deployment at Adaball for extended periods with minimal failures; comparison to boutique manufacturer games with higher failure rates; specific mention of sourcing production-grade parts
manufacturing_signal: Single-unit homebrew builds achieve higher reliability than multi-unit commercial productions because they use premium components without cost-cutting and receive extensive personal testing. Mass production forces bill-of-materials optimization that reduces reliability.
high · Alan and Sean's discussion of making one vs. thousands; George Gomez quote about difficulty of mass production; Sean noting all hardware in 8BB is 'as nice as this shit gets' vs. cost-cutting in commercial production
community_signal: Homebrew pinball scene has expanded significantly in last 5-10 years due to two key enablers: (1) off-the-shelf board sets from Multimorphic, Fast, Bimball eliminating custom electronics engineering, and (2) Mission Pinball Framework allowing non-programmers to develop game logic through configuration files rather than code.
high · Sean explaining MPF's accessibility; discussion of how board availability removed major barrier to entry; emphasis that these frameworks are 'as approachable as programming could be'
design_philosophy: 8 Ball Beyond's success stems from deliberately embracing design constraints (single-level layout, no ramps, classic theme with no attached licensing expectations) rather than being overly ambitious. This contrasts with failed first project that attempted 3 upper flippers and lacked theme planning.

high confidence · Sean confirming board choice in response to Alex's question
“It's hanging on, forcing yourself to do something every day if you can and to think about or to try and plan out some events or milestone in the future that you can look forward to. You just have to endure it.”
Sean Irby @ late episode — Candid reflection on managing motivation through multi-year projects, applicable beyond pinball
“Games have to work... my criticism is reliability... these people are passionate about pinball getting themes they're getting cool art they're doing all the right things and i think when the games play there's an audience there but i'm just concerned about reliability of handmade games.”
Alan @ mid-late episode — Operator perspective on the core tension between passion projects and commercial viability in boutique pinball
“It helps that not only are the board sets that are available, like, really high quality. I mean, the case of Fast and Multimorphic, they're both used in production games. But also the parts that are now available on, like, M-Pinball Life and Marco, like, they're super high quality, too.”
Sean Irby @ late episode — Key insight into why 8 Ball Beyond could be reliable: access to high-quality off-the-shelf components designed for production
“I'm completely out of motivation to do anything else on it. Once you said you've been playing it every day in your living room for three years, I was like, yeah, I think I would be probably ready for the next project regardless.”
Sean Irby / Alan response @ late episode — Acknowledges burnout from extended development cycle and the natural endpoint of a long creative project
high · Sean's explicit discussion of abandoning first project and starting over with clear constraints; Alan noting success comes from 'not trying to nail a theme that people are really passionate about' and avoiding complex molded plastic ramps
operational_signal: 8 Ball Beyond represents rare successful deployment of homebrew machine on unattended location (Adaball arcade) requiring minimal operator intervention. Daily audio crash has negligible impact with 20-second graceful shutdown. Standard pinball maintenance (rubber replacement, micro-switches) sufficient for operation.
high · Sean confirming months-long operation at Adaball with only normal maintenance needs; known audio crash with minimal operational impact; contrast with other homebrews requiring constant owner presence at shows
product_strategy: Building a single homebrew pinball machine now costs equivalent to or exceeds purchasing a new Stern Pro machine ($7,000-$11,000), not including tools acquired during the process. This challenges the notion that homebrew represents cost savings.
high · Sean unable to track final costs after 5 months; Alan's estimation of Stern Pro ballpark; Led Zeppelin homebrew presenter stating costs exceed Stern Pro; Sean's mention of tool acquisition costs
design_innovation: Sean's use of Fusion 360 CAD (industry-standard comparable to SolidWorks) to model 8 Ball Beyond to nuts-and-bolts detail served triple purpose: visualization, project management, and reproducibility documentation. This represents a novel homebrew design methodology.
medium · Sean describing Fusion 360 learning as most fun part of project; explanation that modeling helped with project planning and mechanical visualization; emphasis on reproducibility motivation
community_signal: Public exhibition of homebrews at shows provides critical real-world stress testing that home development cannot replicate. Hundreds of players with varied play styles expose bugs (multiplayer issues, edge cases) that single-developer testing in living room misses.
high · Sean noting multiplayer bugs emerged at shows despite 3 years of single-player testing; discussion of how strangers find unexpected behavior patterns; Alex's comparison of show stress-testing vs. owned-game testing
operational_signal: Commercial pinball operators (Alan, roadsy) now avoid purchasing boutique games despite appreciation for design and art, prioritizing Stern due to superior reliability and proven cost-of-ownership. Higher boutique prices combined with lower reliability create unfavorable ROI.
high · Alan explicitly stating 'we just won't buy a boutique game like it's just not worth it because the prices are more expensive than a stern and they've proven to be less reliable'; examples of specific unreliability (Spooky's Ultraman, generic boutique failures)
design_philosophy: Multi-year homebrew projects face critical motivation plateau after 6-12 months when initial excitement fades and project lacks obvious external milestones. Overcoming requires deliberate daily effort, future milestone planning, and acceptance of obligation-driven work phases.
high · Sean's detailed explanation of motivation transformation; discussion of multi-month stretches with no visible progress; statement 'You just have to endure it'; emphasis on forced consistency and future milestone planning
content_signal: Sean's transparent documentation of 8 Ball Beyond build process on Pinside thread demonstrates emerging pattern of homebrew builders sharing methodology with community, contrasting with proprietary manufacturer development.
medium · Alan referencing Sean's documented build thread on Pinside as community resource; podcast framing of Sean as expert precisely because of public documentation
market_signal: Emerging pattern of competitive tournament players (Sean Irby) transitioning into homebrew design, suggesting skills transfer from competitive play to creative development and suggesting tournament expertise informs homebrew design philosophy.
medium · Sean identified as 'tournament player up in Seattle' who started designing homebrew; his design philosophy emphasizing playability and flow suggests competitive play background
