Lego Technic of the Past Eliminates Apple ][ with Arduino and Touchscreen

[JAC_101], the Director of Legal Evil Emeritus for LVL1 Hackerspace (don’t ask me, it’s their title system), was challenged to a hacking duel. It all started years ago. The person who is now president of LVL1, visited the space for the first time and brought with her a discarded Apple II controller for Lego bricks which had previously belonged to her father. Excited to test it, the space found that, unfortunately, LVL1’s Apple II wouldn’t boot. An argument ensued, probably some trash talking, and [JAC_101] left with the challenge: Could he build an Arduino interface for the Apple II Lego controller quicker than the hackerspace could fix its Apple II?”

Other things that belonged to people’s fathers.

In the end, a concentrated force by one hacker over two years overcame the collective ADHD of many. He began by opening the interface to look inside, a completely unnecessary step since he found it was already thoroughly documented. Next he forgot about the project for a year. Then he remembered it, and built an interface for an Arduino Uno to hook to the controller and wrote a library for the interface. Realizing that sending serial commands was not in line with the original friendly intention of the device, he added a graphical display to the project; which allowed the user to control the panel with touch. In the end he won the challenge and LVL1 still doesn’t have a working Apple II. We assume some gloating occurred. Some videos of it in action after the break.

Strapping an Apple II to Your Body

Now that the Apple wristwatch is on its way, some people are clamoring with excitement and anticipation. Rather than wait around for the commercial product, Instructables user [Aleator777] decided to build his own wearable Apple watch. His is a bit different though. Rather than look sleek with all kinds of modern features, he decided to build a watch based on the 37-year-old Apple II.

The most obvious thing you’ll notice about this creation is the case. It really does look like something that would have been created in the 70’s or 80’s. The rectangular shape combined with the faded beige plastic case really sells the vintage electronic look. It’s only missing wood paneling. The case also includes the old rainbow-colored Apple logo and a huge (by today’s standards) control knob on the side. The case was designed on a computer and 3D printed. The .stl files are available in the Instructable.

This watch runs on a Teensy 3.1, so it’s a bit faster than its 1977 counterpart. The screen is a 1.8″ TFT LCD display that appears to only be using the color green. This gives the vintage monochromatic look and really sells the 70’s vibe. There is also a SOMO II sound module and speaker to allow audio feedback. The watch does tell time but unfortunately does not run BASIC. The project is open source though, so if you’re up to the challenge then by all means add some more functionality.

As silly as this project is, it really helps to show how far technology has come since the Apple II. In 1977 a wristwatch like this one would have been the stuff of science fiction. In 2015 a single person can build this at their kitchen table using parts ordered from the Internet and a 3D printer. We can’t wait to see what kinds of things people will be making in another 35 years.

Pocket Serial Host acts as an Apple II disk drive

[Osgeld] is showing off what he calls a sanity check. It’s the first non-breadboard version of his Pocket Serial Host. He’s been working on the project as a way to simplify getting programs onto the Apple II he has on his “retro bench”. When plugged in, the computer sees it as a disk drive.

The storage is provided by an SD card which is hidden on the underside of that protoboard. This makes it dead simple to hack away at your programs using a modern computer, then transfer them over to the retro hardware. The components used (starting at the far side of the board) are a DB9 serial connector next to a level converter to make it talk to the ATmega328 chip being pointed at with a tool. The chip below that is a level converter to get the microcontroller talking to the RTC chip seen to the right. The battery keeps that clock running when there’s no power from the 5V and 3.3V regulators mounted in the upper right.

The video after the break shows off this prototype, the breadboard circuit, and a demonstration with the Apple II.
