  • Generic Tech Device Section For HomeBrew Pinball.

    This area is for good ideas, devices and general help for the creation of HomeBrew pinball and is not machine specific.

    It is a collection of ideas and devices that have come up in HomeBrew posts that could be an aid to future HomeBrew makers.

    Feel free to add to this list if you think you have an idea or device that you think could aid other HomeBrew pinball makers.

    To start this list off here is a PC program for making .WAV sound effects that allows you to vary the sounds to your liking and capture it for use on the sound effects boards that use .WAV files as there playable folders.

    If you have a .mp3 sound player simply convert the finished .WAV you created into a .mp3 for your use.

    I bought some of these addressable LEDs to play with.
    (Ebay item number 262793423326) It was mentioned elsewhere that they might fit under playfield posts but unfortunately they don't. They have a string of three addressable LEDs on each board. They might be good for pop bumpers though.

      It would be good if you could bring over the sound player to this thread Kev and anything else you think would be best suited here.

      I have asked a mod to paste this thread so it should become a pasted thread soon.

        255 sound wav board on Ebay (item number 222180828182)
        It has 8 input lines that can be used in any combination to play all the sounds that are stored on an SD card. It doesn't have serial input but uses a binary input to access each sound.
        For example. Inputs 2 and 5 would play sound 34.

          I bought some of these addressable RGB LEDs for my Thomas The Tank Engine pinball project and they seem to work well. No item number as there are so many types to chose from. I had a string of 21 and an Arduino Leonardo micro all running off the USB port on my laptop with no issues. While they're cheap and easy to use they are fiddly to wire up being about 10mm diameter. They use the sk6812 chip onboard which is compatible with the ws2812 and associated Adafruit NeoPixel library for the Arduino.

            That's a great link, I was shocked to read the first line:
            "Bfxr is an elaboration of the glorious Sfxr, the program of choice for many people looking to make sound effects for computer games. "
            I've been using sfxr for almost 10 years, so great to see someone has expanded it, will definitely look at using bfxr now
            And yes that statement is 100% correct, it is the #1 go to program for indie game developers looking to make basic sound effects.

              Switch bounce is a major problem with electronics.

              While the switch on the playfield may look like it only works once, in actual fact, the switch may make and break the input signal multiple times resulting in something like a pinball switch multiple scoring or worse case, fire a solenoid multiple times. Both cases we do not want.

              Hitting something like a spinner without a de-bounce circuit could result in a spinner scoring multiple times each spin and a spinner required to score once per revolution could end up with the electronics recording a hundred score pulses instead of 20-30.

              That is a problem created with electronics. It sees everything, input wise and is super fast so it presumes are pulses are valid.

              This is where a de-bounce circuit comes in to play.

              It "cleans" the switch closure to result in just one input that the electronics sees.

              There are many ways to "fix" this problem but what is useful for your application depends on what electronics you are driving.

              If you elect to go the software solution, here are a couple of software solutions depending on the controller system you are using...

                      Digital HD Video Player 5 triggerable inputs.. Bit pricey though...

                        Ideally, it would be a RPi using a GPIO pin to trigger each video for me but I can't find any such project someone has made yet.

                          When you do, post it here ! It would be handy, and easier to use if you cant do a serial link to it. The other trick is if you can do the serial link code to it, use the IO on the Pi as the discrete input to serial encoder ! simplz

                            I was planning on using this on the Aussie Arcade pinball.
