5x 555s, 4x 4017s, 6x 4066s, and 4 Servos = SiniScore 555

Each servo is driven by a 555 circuit, but with a twist. Instead of a POT controlling the servo position, I have 5 resisters that position the servo appropriately. The resisters are "selected" via a 4066 and 4017 circuit. The 4017 outputs drive the 4066 switches to feed power through one of the resisters going into the 555 circuit.
Each 4017 is setup to reset itself on the 5th count, that count also clocks the next 4017. The first 4017's clock is driven from a series of 74HC32 (quad or gates) which has all the switches feeding them.

The 5th 555 circuit is setup as a simple monostable circuit that when triggered goes through a 4066 to reset all of the 4017s. This allows me to reset the score at the start of a new game or at power up.

If I have time this will all go onto a proto board PCB (or maybe a couple). Hopefully, it's okay if some of my circuits are still on breadboards for the 555 contest.

Flippers & Slingshots

Shooter Lane Test

I made a little progress on the play field. There's a shooter lane now, and an arch at the top/back, plus side walls to the play area.

Here's a video of the shooter lane test.

And we have flippers!

 I have started mounting parts to my pinball play field. Below you can see that I have the flippers on there and the in-lane guides. There's also a view of the bottom showing the flipper solenoids and such. Next, I'll be putting the outside walls and the shooter lane wall on, and then the slingshots and ball trough. 

I also have been working on my scoring circuit. This is only 1 stage of it plus the beginning of the second stage. The first small chip is a 555, the next two are 4017s (decade counters), and the last one is a 74HC32 (quad or gate). The switch inputs from the play field will go through the or gates and trigger the clock line of one of the 4017s. Then the output of the 4017 is going through some "glue" then into the 555 which will control a display element. I'll have a 555 and 4017 for each display stage, and as many 74HC32s as I need to get all play field switches connected. Once I have this working as intended, I'll post the schematic.
