Making Tiny Apple Pi: Mini VMac for Raspberry Pi Zero
Introduction: Making Tiny Apple Pi: Mini VMac for Raspberry Pi Zero
First of all.
I do not speak English. I use translation tools to create this page, including this sentence.
Please let me know if there is something wrong with the expression, not just in English.
Well, I recently learned about the existence of Tiny Mac. (It's late)
I was inspired by cgenco and <PERSON>'s web pages. Thank you for creating such a Tiny Mac.
Yes, I started wanting a Tiny Mac. So, I got Raspberry Pi immediately and started preparations. I changed my approach a bit and decided to go with the CLI instead of the GUI. Basically, I installed a minimal Xwindow related environment on Raspberry Pi Lite so that Mini vMac starts when I log in.
At this time I thought about the project again.
Since I am going to produce something a little different from them, I want to have a name for it...hmmm, Tiny Mac exists, Apple Pi exists...well, how about "Tiny Apple Pi"? You like Pi(e), don't you?
Excuse me, back on topic...
Next, prepare GPIO display and GPIO sound card.Both were selected to be connectable with GPIO, and we aimed to fit them compactly in the housing.
However, a problem occurred at this timing. (If I had the knowledge, I could have prevented it)
It turns out that these GPIO-based displays and sound cards cannot be used at the same time due to conflicting pin header signals. (I contacted the manufacturer and understood)
So I changed the plan. I decided to discard the GPIO sound card and use the USB sound card.
There was a problem with the GPIO display, so I contacted the manufacturer again, but it was a simple problem, so I solved it immediately.
Now the basic elements are in place. Of course, we prepared various cables one by one. Oh yeah. 1003
I also decided to build in a speaker. (I'll explain later, it's a 5 watt LR speaker.)
And the housing.
I wanted to have a built-in USB sound card and LR speakers, so I decided to design it from the beginning. This is my first time to use a CAD application. (Although I have used 3DCG applications in my previous job)
It took some time to get used to it, but I managed to complete the basic form.
"What should I do with the output of the housing?"
I thought about using a print service, but I wanted to make it myself, so I checked the 3D printer again. Recent 3D printers are cheap, aren't they? Therefore, I chose the minimum size 3D printer (120x120x115mm) required for this plan. It's less than $ 100 !? The manufacturer's direct sales were sold out, so I bought it at Amazon.co.jp.However, the time comes when this choice becomes a problem.
Now print out.
Yes, the trial and error you all know continues. To minimize plastic surgery. Also, the dimensions are just barely enough, and I have to go back to the CAD application again.
Even so, I made too many details. It seems that I will be troubled by the shaping work after this.
Therefore, wise people should think carefully about this process and start planning.
After shaping and painting, it's finally time to assemble.
Well, I've been doing a lot of trial and error, so the assembly was easier than I expected.
* CLI settings rely on old memories, so please point out if you make a mistake.
** Since GPIO display is used, HDMI cannot be used. In this setting.
Supplies
This is the place of purchase that I used. It is an overseas site including Japan.
Also, processing may be required depending on the shape and size of the cable terminal.
* Raspberry Pi Zero WH: 1pcs (Raspberry Pi 2 Zero if you like. GPIO interface is required)
* WAVESHARE 2.8inch Capacitive Touch Screen LCD for Raspberry Pi: 1pcs
* WAVESHARE USB Sound Card: 1pcs
* 3-port USB hub: 1pcs (This shape and size is important!)
* Portable Audio Speaker Box: 2pcs (This shape and size is also important! 485
