- Ben is putting the finishing touches on the Mini Pinball Kit. The new PCBs from Oshpark have arrived. The board includes everything but the Arduino or the Teensy. It’s got the audio amplifier, the lights, the switches, four MOSFETs, four servos, power regulation, and a bodged in LED light for power. Visit the Ben Heck Page: bit.ly/2G963wU

In this episode, Ben takes a look at the board, makes sure that it works when installed in the pinball case, and works out some finishing touches on the prototype game. Ben hooks up an LED to a socket so he could plug it in and test it. He’s changed the code so that it will turn on the LED that is relative to the switch, 16 switches, and 16 LEDs. Ben goes through each one to make sure everything works, tests the coils, and the servos so that he can write some code and put together a test game.
The team had trouble selecting which servo library to use. They went with the pwmservo library, which is older but doesn’t conflict with the Arduino library. Ben commences with his tests on the servos. He got two of the switches attached to sound events. They’re going to need to add some debounce to the switches. What this basically means is that, as the switch opens and closes, there can be very small fluctuations in the state, it doesn’t fully open and close each time. Switch debouncing can be achieved through hardware or software. You can’t really tell without the help of a microcontroller, but it’s there. Ben adjusts the switch library, to create an array, so that each switch has its own debounce setting, depending on what kind of switch it is, because they might have different mechanical properties.
Ben adjusts the angle of the flippers, puts in larger solenoids, and adjusted the length of the rods throw. He’ll change the layout of some of the feature mounts. Ben fires up Autodesk Fusion 360 so he can make some final adjustments. He makes some progress on the modular wall system as the mini pinball moves closer to a finished build.

The theme should be "The Ben Heck Show". Seems a great tribute as the show comes to an end.
That would be lots of fun, actually.
Have you thought about using an odd number of detents in the pegs to hold walls it should give you more possible angles. With the even number the possible angles are repeated each 180 degrees. It also makes smaller holes possible in the base.
The holes can all be open, and you put a thin piece of plastic or cardboard on top. You can the ship it with a few pre-made sheets with printed graphics for different themes and pre made holes in the right places for layout. In addition, a tool to make the holes in cardboard or plastic sheets yourself for custom designs and layouts. The support from the board underneath should be enough, even with all the holes open.
How about creating a removable "plug" that can be reinserted into the popped out pieces? It would allow the user to test various setups without worrying about a floor full of holes. I understand this would, however, create a higher cost value as those pieces would most likely have to be 3D printed. Although, with a limited number of them, it would encourage the user to plan out first before popping out all the pieces. Measure twice, cut once right?
If the demand is high enough they could (i guess!) go for injection molding for said plugs...
The playfield would probably still need to be covered with something to have a smoother surface, I think. But if that's flexible and/or easy to cut, then it would be fine for anybody to do that at home with just a utility knife...
Exactly what I was thinking... they could keep the pieces they popped out and tape (or use a semi-permanent glue... definitely not wood glue) them back in as needed? And/or include a bunch of flush fitting plugs...
Mid Evil Madness Mini! If Ben ever sells these as a fully realized kit, I would buy one for sure, my kids love pinball!
Just us plugs for the holes?
Very awesome! Can't wait for next week!
how long ago was this project started?
if you make it from the top down you can make it so that the holes are filled with blank stars then swap them out for the clamps but the blanks would still be flush with minimal cracks also maybe a small amount of wood filler to fully level/ flush the holes kids do like arts and crafts plus would teach kids how to Spackle in a rough sense
I was thinking of the same kind of concept .. I was thinking if you made the holders for the walls push in from the top .. .you can make all the holes have "plugs" coming from the bottom to keep the play field "solid" .. you can have a plate underneath to make sure all the "plugs" stay "flush" with the surface. Then you could remove the plugs that you want .. and if you want to change it .. then "fill" in the used holes with the plugs and start over .. or I suppose that it all can come from underneath and have a "retaining" plate to hold all the plugs and wall brackets in place and flush with the surface plate
If you wanted to get real complex ... have the "retaining plate" have the same pattern as the surface plate but not fully through the plate so you could set it all up on the retaining plate (without the walls of course) and then just pop it in to the "surface plate" lol but that may be a bit of over engineering :D
why don't you have the playfield on a hinge so you can lift it up and access the underside and plug up any holes you don't want to use
You can make the plastic wall holders reversible, one side has the wall holder and the other side sits flush on the playing surface, you just need to cut a small lip around the hole border at the top of the surface to compensate for the holder part that prevents to go all the way. Just my two cents. Love this project!
you could use that funky foam stuff so that you can put the pop outs back in place and be level and hole to the weight of the ball
no that dont make sense i will rethink
Loved the nod to Jonathan Coulton's "Ikea" song!
'3D printing is not magic' Finally someone else says it.
And here i was just sitting wondering where the new episode was..
Why don’t you have timeline on in fusion you can go back to any operation and edit or change the order of operation that’s one of its big advantages
gower1973 exactly what I was thinking
My Mini Pinball game will be based on a computergame. I am really looking forward to getting one of this kits in my hand.
Some ideas-Portable GameCube, Portable famicon/NES and a 3ds or DS as a console not a hand-held, I think u should do some of these if u want, love the vids have a good day
Hey Ben love you work just wondering if you could build a camera that takes pictures automatically and sends the via email every 10 minuets the idea is so I can turn it on and point it at my 3d printer so that when I’m out I can look at the photos and see if the print is ok and make sure nothings gone wrong thanks.
Not quite what you asked but Octoprint running on a Raspberry Pi makes a great system for looking after your printer remotely. As for your idea you would need a webcam and a server of some kind (raspberry pi would do) to take pictures and allow you to view them remotely. Octoprint has this functionality built in as well as being able to monitor the printer directly
Peter Barnes thanks
Instead of large holes just make small round holes like 1/8" and make the wall pegs star shaped so they will bite into the holes and not turn. Then the holes won't affect the play field much and can just be covered with the printed cardboard overlay. When the overlay gets too many holes toss it and get a new one.
Hi. I like the idea of the customisable playfield, but i dont like the fact that when you pop a part, your stuck with that, and after all a big part of the fun is to change the playfield whenever you want (special for kids). How about making a closing cap that would stay beneath the playfield. You could print it just in plastic, and have it avaialbe for sale, in case of some break. You could make it that when you rotate it to one side it would close the gap, to the other one it would open it. Maybe is not the best example but the lipstick mechanics come to mind.
Terminator 2. All the motorcycles. All the arcade. All the explosion.
There is a small x86 based micro computer together with it's coprocessor which would make DSP processing possible.
SWBF2 without lootboxes theme!
What's going on with the titling? Title says final analysis but thumbnail says refining the playfield?
And I just noticed since episode 9 you stopped using LOTR puns :(
I would love to buy the kit for this machine. For the theme I would suggest a jungle treasure hunt :)
Theme Idea: Legumes! (On Ice)
Plese do an update on arduino basic computet
Do a Port Washington theme! Fight Depression! Win relationship!
Why does Ben use Illustrator for 2d drawings? I've always heard that Illustrator is terrible for cad-like work, like he's doing.
Illustrator isn't the most intuitive program, but it is quite versatile for creating 2D vector drawings for use with 2D CNC machines. We use it all the time for the laser cutters and I use it to prep files for my vinyl cutter. More expensive, but more powerful than Inkscape.
My pinball would have Dragons!
Then you may enjoy the draft of our first concept. ;)
Where are my Dragons!
Fallout pinball hands down.
1950's sci fi space theme
Spaaaaaaaaaaace!!!!! Theme
Ben's fake excitement...
Scooby Doo theme?
Felix's face in the opening scene looks like he just ripped a heinous fart just as "action" was called and is waiting for Ben to catch a whiff.
Ben wouldn't the game be for married men whose wife doesn't want a full size pinball machine in the house?
World Cup 2018 is a great theme for the pinball
