PROC can handle 24v, yes. You only need to worry about the maximum current, and 24 will be lower, so.

I just hooked some plain Leds up to some shift registers and drove them fine. You could also just always use the rgb as white and it'd look okay if not quite as good.

Team Pinball uses a Raspberry Pi in the Mafia game, I believe. It's not like you need a great deal of horsepower and a simple plug-and-play option should work best.

Whatever you are planning for a timeframe, triple that estimate and you'll be in the ball park.

Pure white isn't a 'natural' looking light colour for an EM. If you want to keep the period feel, I suggest using RGB LEDs and setting the colour to a slight yellow/orange tint to give more of a warm incandescent light effect.

Here’s my post about my EM conversion:

Very cool, Ryan. We'll all be excited to see your progress. Let us know if you need anything during your build.

Some responses inline:

With no displays and no large sound file, the R-Pi will be more than powerful enough. The P-ROC offloads all of the low level processing; so all that's left for the CPU is the O/S and the game rules, and it doesn't take much processing power to run pinball game rules/logic.

Technically RGB is a super-set of white (you can make RGBs look white by turning on all 3 channels and possibly tuning each channel value in software to deal with unbalanced LEDs), but finding white ones would save you a bunch of control channels.

Our PD-16 boards are the ones that control power to the high current devices (eg. coils, magnets, motors). PD-16s can gate any DC power from 5V to 80V without issue.

If you wanted the same power then that sort of comparison would hold, but with the resistance of the coils held constant halving the voltage will just lower the amperage (and power). Make sure you buy mechs/coils designed for 24v systems (and not 50v) so your mechs have the right power still.

Looks like you got some good answers here, the only thing I would add is that computer wise use whatever you are comfortable with while you are building (in my case windows on an old htpc I had lying around), the software can be moved to other systems relatively easily later when you have it all working.

What are you going with software/framework wise? skeletongame and mpf are the 2 big players as this point

I look forward to following along.

Pinball makers site has a pretty good overview http://pinballmakers.com/wiki/index.php/Programming

I'm using MPF for mine, because it seemed to be easier for me not being a programmer. If you know python and are comfortable using it skeletongame/pyprocgame might be a better choice, some choices may come down to what hardware you are all using (see chart on page linked above), but from the sounds of it you could do either. Either way there are good communities of support.

+1 for MPF. It's what I am using in Spaceballs and Rick & Morty.

Hi Ryan,

I personally would recommend you to use a more powerful PC during development. RPi will work for your finished game but it will be a pita during development. See: http://docs.missionpinball.org/en/dev/hardware/computer/index.html.

Do you have a layout design you can show us?

As a further response to the lighting issue, check out the SlingSpot thread and consider utilising a few of those.

Most are now using an ATX 5/12v computer supply or an arcade 5/12v supply for logic and switches (5 and 12 volts) and a 500 or 600W Meanwell 48v supply for coil/magnet power.

How’s this going?

Nice: the first Harry Potter pinball

Seems Quidditch-related, in particular!

cool, following

Impressive! The art style choices go very well with the theme.

Should've gone with Viktor Krum's Pro Quiddich. The students would love that!

Hey Ryan
Sweet pin. Bravo Zulu.

Keep in mind that the dense magic in the air at Hogwarts causes a lot of electrical interference that causes most devices to malfunction. If you plan on routing the game in the wizarding world, you're going to need better grounding.

If it's still not working correctly after that, have a word with Flitwick and see if there's an appropriate variant of a Shield Charm to keep the interference away from your electronics.

Got any more pics of that whitewood playfield assembled? Hope you can get this thing to TPF!
