I don't believe these are made like the strips where you can cut them off.... You would need to buy 3 - 8x8

This is exactly what I did: one 32x8 and three 8x8. It works well and fits nicely into a standard widebody cabinet.

 

Now to get everything into a proper cabinet. This is my CNC design for the LED panel. It includes large holes for the connectors between the LED panels and smaller holes for the additional power. The sequencing of holes makes it clear where I plan to put the 8x32 versus the 8x8, There is a depression to hold all the LED panels and I plan to cover them with some plastic. The top part of the panel is to hold the bottom part of the rear plastic for the playfield glass.

@Outthere What gauge wires did you use to run from the leds to the power supply?  Thx!!

See 71. Wire

I used 18 AWG for the 5V and ground power cables. The green signal wire can be 24 or even 26.

Hi, 

it has been a while, but still I am looking for the firmware for emulating the teensy with an exp8266. Is there a github repo, do you have some details?

 

 

 

Had some time to 'play' with the matrix LEDs last night.  WORKS!!! 

 

I used an esp8266/(wemos d1) as the ledstrip driver (got the info from 'another' pinball board about using the esp8266 emulating the teensy strip controller).

 

Tried a few VPX/DOF games on my desktop and the matrix works.  It is really bright (have to tone down the brightness level)!

 

If you need any help let me know....btw heres the cabinet.xml section that works for my matrix.  (btw:  I have no idea what fadingcurvename does)

<LedStrip>
<Name>PF Back</Name>
<Width>32</Width>
<Height>8</Height>
<LedStripArrangement>BottomUpAlternateRightLeft</LedStripArrangement>
<ColorOrder>GRB</ColorOrder>
<FirstLedNumber>1</FirstLedNumber>
<FadingCurveName>Linear0To224</FadingCurveName>
<OutputControllerName>TeensyStripController</OutputControllerName>
</LedStrip>

I think you will find that the ESP8266 is not fast enough. It doesn't have DMA instructions like the Teensy MCU.

That’s not correct, wemos D1 works as teensystripcontroller unit. See changelog on Mjrs GitHub for DOF from beginning of this year..
Here’s the link so you don’t have to do research yourself…

There’s also a modified teensystripcontroller sketch for Wemos. It has been widely accepted by the French pincab community.
