Re: Another K'Nex 'Slot' Machine

I posted some constructions in this forum on 1st March 2019 ('Some K'Nex Slot Machines'). I have a large collection of old penny slots. I still have my binary calculating machine, Bonanza machine, Penny Pusher and my latest Ping Pong Ball fruit machine. Oh, and my grandfather clock. I only last week...

Re: Another K'Nex 'Slot' Machine

Thank you for your kind comments.

I started it in March and finished it last week. I had many problems to solve on the way, but I like to give my brain a good workout!

Another K'Nex 'Slot' Machine

Welcome to the K'Nex Bouncing-Ball Amusement Machine! Well, what else was I supposed to do during Lockdown? This machine is very loosely based on Bryan's Bullion. Whereas that machine has a spinning pointer, this machine has a bouncing ball, but the concept is the same. Enjoy! https://youtu.be/TqeJI...

Some K'Nex 'Slot' Machines

In 2010 I was at a car boot sale (here in the UK) when I spotted a box of interesting pieces which a boy was selling for £10. It was the construction toy K'Nex, which I'd never heard of. I did some Googling and found out all I could about it. It was apparently the second most popular construction to...

Re: Günter Wulff Astra - Insides

Ah ha! I've figured it out!

Each pulse pushes down the rod which turns the toothed wheel which is part of the randomiser - once every revolution it pushes two contacts together to extend the duration of the spin of the pointer.

I'll be making the missing bit today!

Re: Günter Wulff Astra - Insides

Hi slotsoffun! You have shown a picture of the inside of the Astra. At the top on the right is a solenoid which pulses at the same time as the dice dots are added up. There is a rod attached to this which is missing on my machine. Could you provide a close-up photo of this, together with an explanat...

It all works fine except for the following problem: Inside the machine, at the centre, near the bottom, there is a relay which, when on, activates all the lights. In my machine, the relay never comes o...
