I've never heard of this game before, so this is pretty interesting. I wish you could have shared the whole code of the game though!I am wondering why didn't you multiplex the button inputs and the LED matrix? You could probably then use just a regular Arduino and the wiring would be simpler. I am sure the code is small enough to fit...

The circuit playground does have a small speaker, though its not very loud. I didn't get it in the video but it does beep annoyingly as it counts down, and it attempts to make an explosion sound when you lose.

I'm planning on anonymously placing it on my brothers desk at work. I'm sure he will "pay it forward" around the office...

The LED strip lights up the sides of the cube. Originally I thought I could bring the light from the Circuit Playground to the sides using bent pieces of acrylic as light pipes, but this got to be too complex. Instead I am using the on board lights to show what game mode its in. I'll find other uses for them probably.I stuck with the Circuit Playground because it just can't be beat when you count the cost of the speaker, the microphone and the accelerometer (unless of course you got discrete components and etched your own PCB and such).

I'll update the parts list with the approximate cost (and fix the links, I see they are not working), but here's an estimate:Circuit Playground: $20 (both in a store like Fry's or Microcenter and online from Adafruit).NeoPixel strip: I got one from Microcenter for about $7.HM-10 module: ~$2 from various chinese companies, around $4 or so on ebay.Cardstock: $5 for like 100 sheets at Target. I only used two sheets so technically only a few cents worth..Reflectix tape at Lowes: $3.50. Same here, I only used a tiny bit of the roll.Acrylic sheet: $3.38 at LowesBattery holder: $1Other miscelaneous stuff I had on hand like glue and such.

Thanks! I will be creating an indiegogo campaign after I've built a few more and play-tested it.

Well thank you for that! Yeah I thought it would get more traction but you never know whats going to get people's attention. I thought I had a good chance of winning the contests (I did get runner up though). It didn't come out as nice as I had hoped. But I have some other projects that are much more interesting that I am working on. I'll probably eventually do a 2.0 of this one as well.

No you just tip it over to get them out.We had thought about cutting a slot on the side and then having another piece of cardboard inside at an angle so the balls would roll over to the slot but we were trying to keep it simple... :) But this would be easy enough to do.
