Pi in a Burger King Gameboy Color Build - WIP

obsidianspider

I'm going to try experimenting with ABS cement to join the back of the case to the hinged piece. I bought some jars of baby food as they were the least expensive small glass jars that I could find at 63¢ each. The question now is, do I try the baby food?

@obsidianspider babies seem to enjoy it, the biggest problem, what happens if you love it?

I haven't tried it but from my understanding, they don't use any seasonings and probably tasted pretty bland. I suppose if someone had a lot of food allergies, they would probably like baby food. Well I think they add a little bit of sugar to it for "taste" lol. If you like it you could save a lot of money on meals!

One time when I was very sick and was extremely dehydrated, my doctor told me to drink Gatorade and/or Pedialyte so, since I'd never tried Pedialyte and I thought it would have less sugar than Gatorade, why not give it a try! Well I can't remember which flavor I got (grape maybe?) but it literally tasted like vomit to me. It was one of the worst things I'd ever tried but I've seen small kids and babies drink that stuff like it was Coke/Pepsi or Dr. Pepper. I even saw an interview with Kid Rock saying he drinks it after a night of heavy drinking!

Curiosity got to me and I tried them.

"apple, pear & banana" - just tasted like apple sauce, but was really runny
"apple & blueberry" - more runny apple sauce, but purple, and a bit tart
"banana & strawberry" - the consistency of yogurt, but a weird aftertaste

Important information for anyone building a RetroPie project. Haha.

@obsidianspider gotta try them all!!!

Man, I have never heard of this Burger King Game Boy Color until now. Sounds pretty interesting, although I might not have been alive at that time (don't trust my profile).
So can anyone give me some background info on this thing?

My chemistry experiment leads me to believe these little Burger King toys are not made from ABS. Or at least a polymer that doesn't dissolve in acetone.

In the jar on the left you'll see the red plastic melted in a solid hunk at the bottom of the jar with the acetone floating above it. In the jar on the right you'll see the whitish substance which is acetone and plastic dissolved in it from the Gameboy Advance case I'm working on.

Given that, I'm not sure what adhesive I'll be using to join the back of the red Burger King toy together. I could just use hot glue for now, but I'd like something more permanent. I've read Loctite 401 is really good, but it's also quite expensive.

moosepr

@obsidianspider does the red plastic actually mix with the acetone and then separate out after? maybe if you get it all mixed then you could dollop it on and use it before it separates again?

obsidianspider

@moosepr Its the consistency of chewing gum. I think I'll try bonding two pieces of the blue toy (which has become my test bed) together to see how that works before doing it on the red one. That Loctite 401 isn't carried at any local stores and seems to be selling for $30 for a 20mL bottle. Um. No.

Using a toothpick I globbed some of the red "cement" on to the blue toy to see how things go. It was pliable, but seemed to "dry" quickly.

Using a separate toothpick I put some of the white "cement" on the Gameboy Advance shell to secure the battery door in place. I used Scotch tape to keep the door in place. After taking the photo I saw that the door was slightly away from the case, so I used a few dabs of hot glue to keep the door in place while things set up. In my research I saw that adding too much ABS cement can cause things to warp, so I only put it in four corners of the battery door. I'd rather not wreck the case if I can help it.

I've read that you should let ABS cement dry for a few days to a week before attempting to sand it or put any load on it, so I'll let things go in the garage for a while and check back.

obsidianspider

After waiting a day, the results are good. The non-ABS cement seems fairly sturdy, though I'm not sure how strong it will end up being.

I'm going to hold off on gluing the "hump" on the back of the red toy because I still need to find a source for tiny screws to hold the front and back of the case together, and I know it will be easier to drill the holes without the hump.

moosepr

@obsidianspider would be superawesome if you could do it without the hump!! thats the only thing that lets those toys down in my opinion (i also dont like the GB pocket becasue of its humps)

obsidianspider

@moosepr Too bad I chopped a GIANT hole in the back in the middle to make it work. I'd have to look into cutting out the screen and then dissecting things that way. I don't know of another way to get inside. I am also out of toys to take apart aside from the green one which I'm keeping to show how things started off.

That said, I do have a saved search on eBay for these toys, but the water variants don't come up often.

moosepr

@obsidianspider maybe grind up all the excess plastic you have , then turn it into acetone soup, and 'cast' it inside the hole at the back? you could build it up in layers (but then the hours of working after)

@aloedrink ummm

I am also beginning this project and brought a pink version of the BK gameboy
Now this particular model Im buying has the bulge at the back but isn't hinged like your red and blue versions
Is this still an acceptable case to modify?
