Earlier this year, Target released a handheld “portable” version of the old game, The Oregon Trail. Designed to look like an old Apple II computer, this handheld emulates the 1985 (Apple II) edition of the game.
Now while it's a wonderful display piece and does a fair job of emulating the original game, the controls are a little iffy; the action buttons are ok, but the D-Pad consists of 8 individual buttons arranged loosely in a circle, which makes the hunting mini-game cumbersome, not to mention it’s not the most portable of handhelds.
This is my take on modifying and compacting it into a much smaller shell. My final design’s specs are as follows:
- Measurements: 119x54x17mm (4.7×2.1×0.7in) – originally 92x150x45mm (3.6×5.9×1.8in)
- Weight: 3.8oz (107g) – originally 8.9oz (255g)
- Battery: Built-in 2500mAh rechargeable (3.7V) LiPo battery, with micro-USB charging port and red/green status LED – originally 3x disposable AA cells (4.5V)
- Audio: Front-facing mono speaker with added switching 3.5mm headphone jack
- Improved single-piece 8-way D-pad

I printed the shell/LCD trim at 0.12mm layer height with a 0.3mm nozzle, and I printed the buttons/D-Pad at a 0.08mm layer height with a 0.2mm nozzle.
