I'm getting really crazy with these Altoids.

I have been working on this for weeks and finally it is playable. The small speaker is quieter than expected and the USB hub does not work yet but I'am close. Don't let anyone tell you something is impossible, and if they do just smile and say "it's not impossible I just haven't done it yet". Let me know what you guys think and a possible solution to my USB hub problem. It seems that the pi zero can't handle 2 usb inputs at the same time. From the hub and the Teensy. When it starts with both wired up the teensy doesnt not work. Any suggestions ?

Pretty nice build if I have to say so myself...
(I like how in the first part of the video you went full on HowToBasic on that sucker!)

I love it!

thedudester80

@RetroPieNerd Yeah I got bored and I'm kind of a dorky guy lol. Anything you want to know about this project just ask. I'm having trouble with the USB hub and I got the speaker working, its much louder now lol. Anyway thanks =]

I like that the Start and Select buttons are on the bottom! For the speakers maybe you can cut out a vent for the sound to travel out. I'm not sure where your speakers are so that might not work.

@thedudester80 pretty cool and fun project/video! Nice job dude!

@backstander I have a hole in the top right corner and I just got them functioning correctly. The start and select button placement works great for me. I came up with them being on the side on my last Altoid project. Thanks =]

thedudester80

@meleu Thank you.

@thedudester80 Nice work dude, your getting good at squeezing stuff in those little tins!

How many things are you using USB for? I would be tempted to try and scrap the hub and connect your buttons to the gpio, that way you save on bits to squeeze in, and you gain some battery life too. Have a look here

And the next page is the software setup.

It does mean the pi is doing a little more work, but I don't think you will notice any difference

@moosepr I don't know why gpio didn't even cross my mind? You sir are a huge help. Ill get to working on it later today and let you know how it goes. =] Thanks for the idea.

Ok, that video made me LOL.
Cool project!

celly

Love it! Great build.

thedudester80

@Zigurana Yeah I like to make people laugh. Glad you enjoyed it and thank you for the compliment on my project =]

thedudester80

@celly Thank you. It was quiet a challenge. =]

thedudester80

@moosepr I'am having the worst time getting gpio buttons to work.

moosepr

@thedudester80 oh no! :-( How far have you got?

thedudester80

@moosepr I got everything but my select button and Y button working. Heres how they are mapped on my gpio.

Start=4
up=17
select=11 Gpio 8 is already used for I2S amp so I could not use that.
down=27
left=22
right=23
A=24
B=10
X=9
Y=25
Ground is pin 6 for ground on my permaproto.

The wiring is fine and the button works. I'm guessing its a programming issue. Any thoughts on what I did wrong? lol

moosepr

@thedudester80 the only thing I can think is to check the config on the pi, make sure you don't have spi enabled, pin 11 is listed as the clock signal for spi so that could be conflicting

thedudester80

@moosepr Thats a good idea Ill do that and let you know how it went. Thank you.

@moosepr said in I'm getting really crazy with these Altoids.:

make sure you don't have spi enabled

Don't you need SPI to drive the screen? Maybe I'm missing something, but my GPIO-connected TFT needed SPI enabled.
