Re: Finding a suitable screen - and powering it

If you've got any old/dead laptops sitting around, you could find a driver board for the screen on ebay. Most boards run on 12v or less and have 5v power on the board which you can use to power your Pi. I used a Zero Wireless with a 10 inch screen from a netbook and a RPi3 with a 15 inch screen from...

Re: Powerboost vs USB problem

Sorry to tell you but using breadboard jumper wires is a bad idea. Most of them use like 30 AWG and soldering to the tips just makes things messy and unreliable. I also see quite a bit exposed on some of those tips which is just plain dangerous! You need some proper wire in there, dude! As mentioned...

Re: I need feedback on my wiring diagram please.

As rodocop said you will need to add it between the Pi and both devices. Think of it as a splitter, although it's more complex than just splitting the connections. For a hub I used this one: www.gearbest.com/cables-adapter/pp_213074.html?wid=1433363 Board inside is only about 25cm square, very nice ...

Re: LCD flickering and blurry.

Flickering could be a low voltage/amperage thing. Had that problem when testing with a 500mA USB charger sans battery. Also it's recommended to ground to a contact on the Pi close to the video output to prevent interference, keep them as short as possible.

Re: Do I have the right parts?

Hey man thanks for the reply! I'll switch the grounds. I'll also look into the battery polarity since you mentioned it . Got me paranoid now lol Hey no problem! Didn't mean to make you paranoid but Lipo batteries are no joke! I did connect mine in reverse for about 2 minutes on my build first time ...

Re: I need feedback on my wiring diagram please.

Not bad but I would change a few things to make it a little easier. :) 1. No need for a seperate power strip. Wire from power boost to Tinkerboy, Tinkerboy to Pi(vice versa would work, too). From there you will have enough left over to power and ground all of your remaining components with 5v and gr...

Re: Do I have the right parts?

Well after being gone for a while I'm back :) I heard so many mixed things about the pi zero w. People saying it does not run mame or neo geo well. So I went out and bought one to see for my self. I am very impressed this little board kicks ass! It exceeding my expectations and re affirmed I want t...

Re: Prize Parts - New GBZ - Need help too...

With that screen bracket, you will end up needing to hot glue or make something else to hold everything in proper locations. I used a piece of thin clear poly-carbonate sheeting in my build(Makralon 1mm/.040"). Drilled and tapped, held M2 thread securely. Alternatively you could print a new bracket:...

Re: White GBZ First Build

That's the same AIO board that I have in my first build, how did you setup your wiring for the buttons (XYAB Start, Select.... etc). what is the diagram? Here is a diagram on Tinkerboy's website: http://www.tinkerboy.xyz/how-to-wire-the-micro-usb-4-wire-data-cable/ Really all you need is a micro US...

Charging/USB over 4 pin 3.5mm Audio Jack

I have an MP3 player that uses a 4 pin stereo headphone jack for both audio output and USB charging/data. Uses a cable that looks like this:

Anyone ever used this in a project before? Seems like it would be handy for small handhelds.
