Pachinko machines are common gambling games which are played in Japan, and are still in use today! Before bringing the Pachinko machine into the modern era, Ben and Karen need to figure out how the machine works and give it a cleaning. For example, the launch arm doesn’t work unless enough balls are loaded into the Jackpot hopper. Their plan involves using switches to detect different states in the game such as success or failure.
Ben uses a low force micro switch attached to 3D printed parts to allow sound effects to be added and to detect every possible state of the machine. The machine will have lights as well as sounds. Ben grabs an Atari jaguar power supply, a single board audio amplifier, a “Prop Dev Stick” microcontroller that can do audio and has an SD card built into the board. Ben adds external circuitry to the microcontroller by wiring up a bank of transistors so that they can control higher power lights using the lower power microcontroller.
Ben uses a bunch of 2N4401 NPN transistors and does a test to see if he can pump 12 volts into the lights and control it with a 3.3 volt microcontroller. He uses bayonet style 44-42 bulbs rated at 6.3 Volts and duty cycles them so that they are only on half the time. This will allow them to work properly without being burnt out. Ben hooks up six transistors and six ports to the PCB to allow lots of options. He also uses a regulator to step down from 12 volts down to 3.3.
The 12 volt input is the same thing that goes to the audio amplifier. There is a capacitor for filtering that. There are transistor controls for six lights. The transistors are hooked up to the microcontroller. The 5 volt regulator takes a 12 volt max and knocks it down to 5 Volts before going to the microcontroller board. The audio output jack also goes to the audio amplifier. There are also four switches hooked up to the PCB: ball load good switch, good launch switch, jackpot switch, and drain switch. Ben mounts the PCB to the plastic on the machine. He then wires up the lights and the switches.
The Panchinko machine will include a system on light, a ready light, and jackpot lights. Once the lights are set and the rest of the logic is working, a selector is added for different sound effects.

sure wish you would offer this as a kit for existing pachinko machine owners!
A childhood friend's dad brought one just like this from his tour in the Navy. We were told it was "broken" (i.e. missing the metal balls). But we later discovered that some glass marbles were just the right size. We had such fun playing with it after that. As an adult, I often wondered what it would have taken to refurbish it. So, thanks for some closure on that.
11:57 _"there are four lights!"_ Ha, that ST:TNG Reference! Really good episode that one.
I live in Japan and have been in the pachinko parlors here. I have never seen one of the older machines. Man are they different. The newer machines don't have a launch switch like the one in the video. The newer ones have forced air that propel the balls into the machine. You have a knob that you can use to try and control the airflow rate. So basically game play goes a lot faster. Seeing the older machine was very interesting.
I know this is an old comment but thank you for it, I did t know new ones use compressed air!
Ben, you are very inspiring. I plan on redoing an old pinball and this video gave me really good ideas. Thanks for explaining the electronic wiring.
Keep those awesome videos coming.
Omg this board is amazing, I just bought a machine for 20$ that’s working but needs electronics in it, what id give to visit you guys and work on mine together, great work!
Fixing up an old Sankyo like this rn. Thought about adding something like this, but way too much. Just going to do the lights up and keep it old school. I think the playtime would be mire relaxing without sounds effects.
Great video as always Ben!
Cool finally some really outstanding fancy hardware
I love this show, watched every episode and now re watching them over :)
Great video as always! The best start for the weekend :)
That was pretty neat to see a pachinko machine getting a bit of fixing up, even though those ones are mechanical and don't even need the sound effects.
great job, I love the rebuild videos.
I really enjoyed this episode, good to have some good old fashioned teaching us about transistors. Although I feel a diagram could have come in handy showing *how* his test setup was wired, as the wide shot wasn't quite enough.
@The Ben Heck Show : I wonder if you could do something similar with table soccer? A switch on each of the players feet could activate commentary, the sound of the crowd could get louder the closer to the goal. Obviously goal switches (and the crowd goes wild). It would be funny to give the players silly names too, with a set of random comments between kicks etc... What do you think?
Way to go! Now I got to know something new again.
Is there an already assembled 'Prop Dev Stick" for sale anywhere? I could not find it (only the schematics).
I wouldn't say it's priceless now, but it sure could be sold for about farty thousand dollars!
I love these videos... great stuff!
excellent episode
Hey guys, cool episode! Ignoring all the ridiculous comments, this was a funny and interesting video. Thanks for making your friend a part of the show, Karen!
To note: the outro audio was really low.
THE episode ben heck almost died of laughter xD
best ep yet!
LOL... "There are FOUR lights".... Doesn't get much better than that.
The number of balls in this video is TOO DAMN HIGH!
Nice to see the Xbox in the intro being used to play games awesome work love the channel keep it up
Now that was a fun ep
Wow this is nice!
I have one of these. Thank you for this video I may want to fix it and keep it.
Just picked up my 4th pachinko machine in about 6 months today. Was not trying to collect them, but they keep falling into my lap.
Might have 2 more coming soon as my friend looks through his stuff.
Oh God, Konami got to Ben Heck! It's all Pachinko from here! :V
They really need to update their intro.
The fart sound thingy needs to be in there!
Beeeeaaaauuuuty! Love the Dave Jones reference.
When I was a kid there was a parlor down the street for me and I used to play this. Ones just like this from the 70s. You would pay a few dollars
I haven't watched any of your videos for a while. This was a really great one though.
and thumbs up on the beard. engineers and beards belong together
Im assuming you only put a resistor on the base of the transistor?
Does that resistor value have to be calculated, or do you just use some standard value?
That's awesome! I can't say i have seen one in Australia ever.
HIT THE LEVER!!! i bet konami loves this episode >:)
I just got 2 old pachinko machines both need work. This was so cool to watch. I don't know electric stuff or connections. Do you or anyone convert these machines over like in this video? I would love to get more info on this if possible. Thank you :)
Very interesting mod to the system. Great job you guys. :D
Ben, I think you should check into some Teensy 3.2's or 3.5's since they are Arduino compatible and also their digital inputs are 5V tolerant. The Teensy 3.2 has one analog output and the Teensy 3.5 has 2 analog outputs. Plus the Teensy 3.5 has a microSD card slot so you could easily store some audio files on it for more interesting mods. :D
"There are four lights!" lol Nice TNG reference, Ben!
Best single episode project so far, topping just barely the EEV Dave See'nSay.
That's quite an upgrade and improvement. People sell a lot of those on eBay and antique stores that don't work and need restoration and are sold at very cheap prices. He'd have to purchase them but if they don't work, they're cheap. But just think of the prices he could sell them for if he gave them upgrades like that! Vintage pachinko machines that are modern at the same time!
Once again, "oh this ben heck video looks interesting.... oh hey it's FRIDAY!!!!"
Happy to be a pleasant reminder for you.
Enjoyed! I think I can figure this out, but a circuit diagram would be helpful, not sure if you dropped a diode in there and not sure how you are doing the 2 wire to the transistor. Also what control code did you generate as I'm not sure how to signal the LED as a "duty" cycle. If you are going to publish these, a link to the code (assuming you want to share), circuit diagram (back of a napkin or white board is fine), and .STL would be wicked, cool, awesome. Think I can figure out the BOM from the video. Thanks!
Ben, next laptop you make (or revisit) you should put a "keymander" in it so you can use a keyboard and mouse
Love the rebuild & idea of sound effects. My problem now is that fill ball tray light switch which can't be fixed. Where does one get a micro switch? The win switch is ok accept I will have to cut the plastic weld over one contact arm for the weld/solder just fell off.
that was fun!
Most I've ever laughed during a TBHS episode!
Fart mode is epic! Now I'm hungry! xD
Do you eat farts?
Stranger I fart my eats
I eats my farts
Comment reported for "Sexual Content"... :)
Very funny. :) Great build.
Mattel Football with crowds, narration, tackles, kickoff, etc... good luck.
I'm gonna hear Felix saying "Please load balls" in my head for the next month at least
Awesome project as always! :)
Do you think it would be possible to make a playstation 1 that would run games from a solid state hard drive using all the original hardware except the disc drive? I know emulation is easily available but I'm interested to know if it'd be feasible.
love the subtle Next Gen reference.
i envy electrical engineers who can play around with circuits like its a walk in the park
Nice! Now I know what to do with my pachinko machine! LOL
Good video.
Hi,
I don't know what's wrong with my game.
Do you have a website I could send you pictures of the back? Thank you.
Using a ULN2803 would reduce your soldering work quite a bit. It's my favourite component!
Love the Star Trek reference "There are FOUR lights!"
holy crap, you guys got the same pachinko machine that I found!
what's going on with the audio mixing on the credits
Said it before and I'll say it again, I'm diggin' the beard.
At the start of the video, if you wait a bit then skip ahead, you'll hear "The Ben Heck Shom"
Also what exactly is this driver board, I don't see a name stamped on it. I've used SparkFun WAV Trigger (robertsonics) but I like the smaller profile of this one?
Ben used the prop dev stick that is mentioned in the screen text. Ben got it from his friend at Macrofab. You can check out his github that has details about it. github.com/LonghornEngineer.
Dang it Ben!
What did I just say about those side burns?
Whoops, the Element 14 outro is very quiet. Anyway, loved the episode!
Was Ben stood in the parking lot while doing the voice over for the element 14 bit right at the very end?
This is the exact same model of pachinko machine my grandfather brought back from Japan.
Awwww this is so entertaining......keep up the wonderful work
you beautiful beautiful people
Just an FYI the sun off snow will burn you like crazy. Sunscreen when you are skiing is VERY important. Also was it snow, or white sand desert?
So which episode IS that line "I want to live in a world with Star Wars again!" from?
Neat. My uncle has a copy of that same machine.
Why is not one of the sound options Konami Mode?
Could someone post a picture of the diagram with this circuit he made? I want to build one, but would hate to waste time trying to figure out what I'm doing wrong with such a limited knowledge base.
I need a "Balls Ready" and "Jackpot" switch of my own.
11:57 StarTrek TNG reference "There are 4 lights!" I laughed... No one else did.
I love the nod to EEVBlog at 6:54
Can you post a circuit diagram and program?
My father in law has been asking me to try to repair one of these. Might have to do something like this myself.
that was cool
"He got it for free" lol I know the feeling I had 2 Pachinko machines from that era, I couldn't even give them away. Most people have no clue what they are here in the States, much less want 2.
Where did the music and sound effects come from?
I believe I found some of them on newgrounds.com. I don't remember the other site I used, but it was all CC.
Do a "Tomy Turbo Dasboard" hack / rebuild / upgrade?
"We can 3d print the parts that are missing!"
OH MY GOD THIS ERA WE LIVE IN! I NEEEED A 3D PRINTER :3
When the manufacture doesn't make parts anymore for this machine.
Omg can I have this!!!!!?????!!!!! Great job!!!
Whoa the music started blasting at 16:07!
it would have killed the headphone users.
This is all so appropriate considering the name of the pachinko maker "NISHIJIN" could be translated to "West People" depending on the Chinese characters intended. It is in romaji though, which is alphabet letters, but the most common Japanese words were the basis for my translation.
8-bit mode really suits it well
I have one of those machines and there is another problem it would be good for you to solve. Could you devise a system to move the balls from the bottom collection container back up to the top input container? I would like to mount my machine in a cabinet and it would be nice to automate this process. Thanks.
Another fan suggested that last spring, but we didn't have a machine at the time. Maybe we'll try it this year now that we have one.
You woke up at a friends place!? Explain...
Without previously noticing the pachinko machine . . . .
Anybody smell a bit of...."spirit" in the air?
Mickel she banged a guy for his pachinko machine
I know, childish of me, but I laughed every time "balls loaded" came up! :b
Hello, Ben, I'd like to suggest a project. A wireless HD. Modify an HD by placing a wireless module so that you can transfer files. What do you think?
BD131 would have been the way to go especially if you use a heatsink and mount the BD131s onto the heatsink use 3 pin connectors to connect the BD131s to the PCB which also holds the micro-controller.
loads of balls jokes waiting to be made!
Does anyone know the name of those white 2 pin connectors he uses?
2 pin molex connectors
The e14 outro title card audio is very quiet, just so you know
Any time Ben Heck could show us how to build a Commodore 128 power supply? Maybe make one that works on rechargeable batteries? 😍😍😍
You should make a bomb game like that game where one person decodes the bomb moduals and the other has to follow the directions
