In this Instructable we are making a slightly larger version of the Tiny Mac. There are a couple of reasons you might want to make this version.
Supply change issues (it is almost impossible get a Raspberry Pi Zero)
A larger screen
This version uses a 3.5 inch display. This version’s is about 25% bigger than the Tiny Mac and about 40% of the size of original Mac. I’ve also included a version of the case of the Pi Zero if you have one. Look at the Tiny Mac for Pi Zero specific instructions. Follow these instructions for the screen drivers.
I will refer to the original Instructable for much of the process. This Instructable will only cover the significant differences.
Let’s assemble what we need.
For The Raspberry Pi:
- Raspberry Pi 3A’s or Pi 3B’s (the case won’t accommodate the 4)
- A 40 Pin Header
- A Micro SC card at least 16GB
- A compatible power supply (one with an integrated On/Off switch is a nice to have)
- A keyboard. The keyboard is only really needed for setup… unless the applications you will be running need keyboard input. Not sure I’d write a novel on this ;-). You can borrow a keyboard from your desktop.
- A mouse, wireless is a nice to have.
- Waveshare 3.5inch LCD For Raspberry Pi, 640×480
- A SHORT GPIO 40 pin Male to Female ribbon cable. An 8″ (20cm) should fit. Anything much longer would be difficult to squeeze into the case.
- Bluetooth speaker (optional). There are plenty of cheap options out there.
For The Case
- 3 – M3 X 12mm Hex Socket Head Cap Screws. Here is a nice assortment.
- 3 – M3 Hex nuts
- Beige PLA Filament
- Blue Painter’s Tape for Raspberry Pi 3 version of the case
- 2.5mm Ball Allen wrench. Here’s a full set of both Metric and US wrenches.
- 220 grit sandpaper
