I loved amusement arcades when I was a kid, so it made sense that when I started my apprenticeship and had money to buy components I built a small slot machine. It was based on CMOS logic chips and had proper payout functionality.
I can remember building this at the family table, which was not ideal since I kept having to move all the stuff at meal times.
Please excuse the less than ideal visual and audio. I'm filming where I can at the moment.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.

Man just watching the video makes me want to take a trip to the nearest Indian Casino (124 miles north east of here) and throw away fifty bucks so the Indians can perhaps buy a can of beans from what they get from the mob that runs those places. The sound and feel of those slots make my heart race as I dream of seeing the 777 come up.
Of all your videos, I find this one particularly fascinating. I've always seen you as very clean and methodical which contrasts with your resourcefulness and flourishes of chaos in an earlier iteration of you. It's very cool to see where you started and where you ended up. It's a poignant example of what dedication will net you.
That is excellent.
Lets see you build a new one!
Dafuck? This video appeared twice for me on the video page of Clive
"focus you f**k" (aVe) lol
Interesting. Too bad there's no good way to analyze the circuit. Using 4017s for the spinners would seem overkill, since they can count to ten, but perhaps those were more available than e.g. divide-by-eight chips? It would be interesting to know what chips were available to work with. Otherwise, I would guess in addition to the 4017 for the lights, there was probably a another used for game sequencing, which stopped each "wheel" and then hit the solenoid as needed for the winning combinations [e.g. on steps 5 and 6, hit the solenoid if any winning combo is showing].
Do you remember your thought process about winning combinations and probabilities? The special six-coin payout for yellow seems curious. Was that intended to show that you could do such a thing? I remember doing some "slot machine" computer programs around that time, and biased the wheels toward certain outcomes so as to allow more frequent low-value payoffs. Yours, though, had the added interest of a coin-dispensing solenoid.
That's fab! It's nearly as dodgy as my Doctor Who-themed fortune teller machine.
Your beard was talking
My first thought was "Oh that's such a simple job with an Arduino". Then I realized which era it's from. Shame. SHAME! Please forgive me…
Dont know what is most impressive, that you could build that as a kid or the shape it is in (working, no dust, no rust, no yellowing of the connector etc… )
I would love to see you build a 2.0 version now days 🙂
How are the odd's controlled?
I think you should make a new project like this one 🙂
I would build a visible "slowdown and stop" into a future machine though…
They would go so well in chip shops or any space where there's a short wait to receive a order and it can be made to take any spare coins players have to use I'd be building some out of small safe boxes an seeing how they go
