Thanks! The source code provided has a few bugs in it. We only spent
a week on it. Since that was published I implimented multiple balls,
coin credits, high score record, and various other features.

Same as the control board - we simply knew what it should do. ;) The
embedded systems background paid off, I do similar work at the day job.
That's ... amazing! You must be really pleased with it!
Very nice, something I would love to try one day. Nuggy on this
newsgroup is working on a homer right now, google under coconut island
for contact details.
Cheers.
Very impressive ! Congratulations !

The shots aren't layed out very well, I didn't have time before the
CircuitCellar contest entry to do a whitewood and a final.
I'll likely be taking the machine to the 2007 Colorado Rocky Mountain
Pinball Showdown in April - swing by to check it out if you get a
chance! http://www.pinballshowdown.com
I think I'd get some of those shorty pinball legs for it myself, but
that's so minor... No matter what it looks like alot of fun for the
younger pin-head, and i bet building it was a blast too!

Big congrats to you! Enjoy your handiwork to the fullest!

PS Was that the Shoney's bear I saw in a couple of pictures... man I
miss that buffet....
Anyway, sounds like the machine and I will be at the Chicago 2006
Pinball Expo as well. I'll likely be presenting at one of the
seminars. I will expect no complaints about the new legs ;)

The shortest commonly-available legs are 27 inches, for Gottlieb
games from the late 70's on. New ones available too at PBR.
Some bingo and EM arcade games used 25 inch legs, but those
won't be found new and may be harder to find used. Perhaps a
post like" WTB: 25 inch Bingo machine legs" might help.
But with the Gottlieb legs and mounting holes for them in the
cabinet that are higher than usual, you may be able to use
27 inchers. The upper limitation is probably where the top
of the leg would hit whatever lockdown bar setup you have.

27" is the shortest??!? I have those on my Gottlieb Black Hole(s) -
and they don't seem very short to me. I need legs that are more like
21". I don't want it to come up more than 4 inches or so from the
bottom of the cabinet, as you would see on a typically sized pinball.
I hate the way Mushroom world looks in the low position (where the leg
comes up to the top of the machine).
Are you the GSound guy? Could have used your help on the sound board -
I'm still pfutzing around with sound on this machine.

Nice work!
How does the bear head work during play?
Excellent job!
I've been dabbling with replacing the hardware and software on
otherwise "dead" pins using PLC hardware and programming. I've done a
couple so far. Your solution has some attractions over and above mine.
A couple of questions comes to mind:
1) Did you multiplex the switches and lamps or just do them direct?
2) What did you use for an interface for any coils? Clearly, they draw
more current than any micro board can deliver.

Pin resurrections! I like it.

The machine differs a bit from the "real ones" (I have anyway).
Although, I do like to think it still falls in line with Pinball
tradition and natural evolution.
There is no matrix on the playfield. The 6.3v AC power tap on one of
the transformers snake routes to all the lamps. Ground is also snake
routed through all the switches. Each lamp and switch also has a long
run back to the control board. My machine only has about 600ft of wire
(big modern machines have nearly 5x that). Clearly not in need of
reducing the long hauls just yet.
I used this technique on the solenoids as well. The control board
sinks all its outputs (connects ground for active). 38V DC is snake
routed to all the solenoids (knocker, bell, flippers, pop bumps).
There aren't any relays anywhere on this machine either (I have a
feeling you're wondering).

Micros can only sink/source on the order of tens of milliamps (about
one LED). I'm using modern, logic-level, high current, low resistance
(RDSon) MOSFETs. They can draw about 20 Amps without even breaking a
sweat. Not cheap though. In high volume designs we wouldn't see
people using logic-level, it's cheaper to make more complex staged
current designs.
The software performs PWM on each output to "tune" their strength.
This allows me a "don't care" on the windings - which is great since I
hate mucking about with arbitrary coil windings.
If you're curious check out the schematics, software and board layouts
on the webpage. It was all part of my entry into the 2006 Atmel
Circuit Cellar embedded design contest.
As for a DVD. We'll I guess for now you'll have to see my chats at Pin
Expo (assuming the Stern bus gets back in time) and Rocky Mountain
Showdown (assuming www.pinballshowdown.com reappears?).
