I have decided to update all the files on HackaDay to reflect the changes I have made recently to the Tiny Joypad Megazoid Variant. There have been minor changes to the PCBs and case design which mainly iron out small flaws in the design. I will also be uploading the EasyEDA files. I consider the PCB designs and case designs open source, and wave any and all "implied" rights to the design. There may be however some copyrighted material (images/code?) within the project.

PCB changes include an on/off button that pokes out of the case a bit more, a slightly more centralised screen, SMD placement alterations and some cosmetic changes.

The case changes accommodate the new PCB design and have the addition of neodymium magnet mounting holes.

There is nothing worse than investing time and money in someone else's project only to find there are flaws in the design. In the interest of full disclosure for a prospective builder, here are the issues I am aware of :

Issues:

1. The power switch doesn't really protrude from the case. I manage with the side of my nail, or you could use a cocktail stick / match etc.

2. The screen is 1 mm off central when in the portrait aspect. You might not have noticed... you will now.

3. The sound is quiet. It's a tiny speaker with no amp, so it isn't much of a surprise. It is what it is :)

Problems that might come up:

1. It wont turn on.

• Have you checked there is a programmed and working game cartridge inserted?  It wont come on without one. Also check the battery is installed correctly. Positive down. Then start thinking about looking at your soldering.

2. The joystick falls off.

• It wont really hold on there without a small amount of superglue, however only do this after you are 100% sure you no longer want to take the case apart.

3. The screen case and joystick case are misaligned

• We did test the case designs on a couple of printers and with different materials, and are satisfied it will go together without issue. Slight variations could be caused by a badly aligned 3d print bed, but another cause could be that your joysticks female connecting pin is not level. You could risk just bending it a fraction.

Adding a fabrication video which I had to split into 3 parts. It's 30 minutes of your life you'll never get back, but perhaps if are going to make a Tiny Joypad it might prove somewhat useful.

I added some 3 x 1 mm neodymium magnets as a test. They do add a little extra grab, but are perhaps too much work for most people. I'm going to leave this off the design, and people can play around with the idea should they wish. Melted the holes using a heated drill bit and superglued them in by the way. 

I made some pin-out boards for programming the cartridges. They got progressively less hideous, but are still an insult to the eyes. You don't actually need these, but they are useful to me who is going to make a few Tiny Joypads. I did cremate one ATtiny85 by getting the connections wrong. It was not a happy moment.
