Brian's GBZ Ver.2 (w/Custom boards!)

Update 2016.6.14

Finished the drawing for the cartridge reader:


Now I can start placing components on my backboard!

So this is going to allow us to use the sd card and oem gameboy cart?

This allows us to install the cartridge reader from the dmg onto my custom board

The boards have been shipped!
Will get them in about a week.
Here are some images:



I kinda messed up the front side a bit, the jumpers at the top I forgot to add the rectangle surrounding it, but it really doesn't matter since the only thing you can see after you install the board is the backside

Also made a stencil for it:

The boards I've arrived today!



Some side by side comparison with the old boards I made:



Still waiting for other components to come so I can assemble them and test them out

Looking good Brian! Let us know how the buttons work on the Pi etc!

As an update to your question in my thread about the 555 timer for backlight stuff, I put the schematic (that I linked) into a circuit simulator and it performs as expected! Using a 10nF capacitor worked out to 1KHz. I've made a board using this so waiting for that to arrive and can tell you if it works in reality too then

Cool, thanks! The only thing I'm confused about the circuit is, in the post he gave us the equation for frequency 'Frequency = 1.44 / (R1 * C1)'. But, R1 is a potentiometer, so the value will change which means the frequency will change as well? That's a 100k pot so the frequency should change rapidly according to the equation..

Update 2016.6.24

I solder on the usb connectors and realize som problems:


The right side is what I originally planned to do, solder the usb connector vertically so I can give more space to the battery. But, sadly I found out that it will be too tall when any usb device plugs in...
So I went for soldering the connector horizontally, but this way it will kind of get into the batteries way, I won't be able to lay the batteries flat among the board, they will now be hovering on the usb connectors. But this isn't really a problem I still got enough space to fit in 2 batteries. The only downside is that I have to lift up the batteries to review the usb ports. (Not a big problem as well, wont be touching the ports after I plug in Bluetooth and wifi adapter )
