Here is a older development picture of the system. This is a PinHeck REV7 with a custom RPI3 CM carrier board I developed grafted onto it.
Quoted from rubberducks:
Would it potentially be possible, if enabled as an option in software, to do a USB audio out if there's an unused USB port?
No it wont be possible without major code changes. The PCM5122 is probably much higher quality then any USB DAC you are going to use. 24bit 44kHz Audio.
SMT placement done on the prototypes. PTH should be done by tomorrow then preliminary testing.
Quoted from SpookyCharlie:
3 games made here use the same exact board... only AMH and AC will be different. All a part of it, and no different than Stern using SAM, Spike, Spike 2, etc.
REV 1 was a board that had a PIC32MEGA devboard socketed on it. edit: I remember. Ben still runs this board for testing code changes.
REV 2 and REV 3 we added and removed features trying to figure out what we needed in a board set. It had a 16-segment display connector on it!
REV 4 First board set AMH ran on. A couple really early AMH run on this board set. The game shown at Chicago 2013 (i think?) had this board revision in it. It was pretty hacked up.
REV 5 Is the production AMH board. I think we had a couple improvements over the run of AMH.
REV 6 Never even made a prototype. Had some pretty radical ideas but we ended up not going this route.
REV 7 Majority of Spooky's games run on this board set. Current revision is REV7D. Lots of changes to make manufacturing of the board set easier over the life of the board set.
REV 8 New board set! Probably the most radical change of them all. As noted before we are considering this revision the End Of The Line. The board set has seen many changes and additions since we started it (2012? maybe 2011) that I would personally like to start from a clean slate after this.
Quoted from toyotaboy:
Also don't forget it's not like Ben is just sending the boards off to some prototype house, and then getting them stuffed at some no-name contract manufacturer.. Longhorn engineer (correct me if I'm wrong) has his own machine to wave solder boards so costs are kept low, even with revisions.
Correct, We have a a low volume high mix electronics assembly line here in Houston. Specialize in this kind of stuff
Quoted from toyotaboy:
However if you're going to optimize cost it's probably better to design your own board.
Quoted from Claires-dad:
Ability to remanufacture them, going forward?
Totally. The best thing about our operations here in Houston it is easy to make more REV5s (or REV7) as needed. These board sets are also very easy to repair since currently all the parts are being manufactured (no EOL) and there are no custom ASICs.
We have been talking about pushing the platform out to hobbyists to enable more people to develop on the platform. Currently the only thing stopping this from happening is documentation of the software to make it easier for someone to pick up and use. We also would need to figure out how to protect the software IP Spooky has created around the platform to prevent another incident.
Quoted from gstellenberg:
If anybody else is planning to start a pinball manufacturing business (it seems to be the thing to do these days), please contact me.
It is one thing to comment on R&D and manufacturing but trying to push your own product in another manufactures thread is tacky.
Quoted from jwilson:
You’re right, they’re not 5 cents, they’re only a penny.
Yes lets base part of our supply chain on a none authorized source of parts! What can go wrong. Surely not counterfeit parts or exploding parts!
Quoted from jwilson:
Why continue to expand and redesign a control system with limited capabilities, going as far as to leverage a completely separate computer for display purposes, when a mature, proven and well-supported system has existed for years? That was the question. It was never actually answered, I was just downvoted into oblivion because "reasons".
Cost reasons. I won't say what the difference between PinHeck + R&D verse buying PROC out right but the PinHeck + R&D time is cheaper.
Quoted from NeilMcRae:
going to be at TPF looking forward to playing ACNC - one thing that would be cool in your building of machines, perhaps too late for this model, would be to include HDMI out (even better with sound too) and/or 3.5mm headphone jack - more and more live streamed events and streamers.
REV8 won't be able to do HDMI out but you can split the audio with a 3.5MM headphone splitter. In the future I would like to have HDMI as a kind of backup on the board. Then you can easily split that to another screen or use any kind of screen that you want to. Maybe we can get OLEDs that are 15"
Audio DAC boards arrived. This will be embedded on the Pinheck REV8 but I made a separate breakout to try several different iterations of component selection and layout ideas quickly.
