I may be stretching the idea of "Misc." for this particular forum but I thought it would be fun to share this project as it was done using what I have learned from scale modeling.
The project in question was to take an old Sega Game Gear (portable video game system from the 90s) that I had refurbished and gotten working again and give it a custom paint job. This system is intended as a surprise gift for my son.
The inspiration of the paint scheme is from the Halo video game series. I tried to grab colors from the palette used for the main character, Master Chief (a space marine. No, not the Warharmmer kind 
).
The system comes as a pretty basic black on black color scheme.
Masked it and applied the base army soldier green in preparation of applying a little silly putty to create a camo effect.
Initial application of silly putty required some refinement. ;)
Did a tiger stripe like pattern.
The Master Chief's helmet has a gold colored visor as part of the faceplate so I thought it would be cool to frame the screen in gold. I enjoy the subtlety of the camo pattern.
Final product with a satin clear coat. I printed the decals using images found online, screen captures, and scans from game materials. The buttons and front glass were replaced with aftermarket products.
Apologies as I couldn't get the white balance corrected so the colors are slightly off.
Was an uber fun project to do and rewarding to be able to use the knowledge gained from scale modeling to create this project.
This project was made in possible in part with help from everyone on the forums and the tips and tricks they post. Thank you!
