Analyzing The Code From The Terminator’s HUD

April 15, 2024 by 38 Comments

The T-800, also known as the Terminator, was like some kind of non-giving up robot guy. The robot assassin viewed the world through a tinted view with lines of code scrolling by all the while. It was cinematic shorthand to tell the audience they were looking through the eyes of a machine. Now, a YouTuber called [Open Source] has analyzed that code.

The video highlights one interesting finds, concerning graphics seen in the T-800’s vision. They appear to match the output of various code listings and articles in Nibble Magazine, specifically its September 1984 issue. One example spotted was a compass rose, spawned from an Apple Basic listing. it was a basic quiz to help teach children to understand the compass. Another graphic appears to be cribbed from the same issue in the MacPaint Patterns section.

The weird thing is that the original film came out in October 1984 — just a month after that article would have hit the news stands. It suggests perhaps someone involved with the movie was also involved or had access to an early copy of Nibble Magazine — or that the examples in the magazine were just rehashed from some other earlier source.

Code that regularly flickers in the left of the T-800s vision is just 6502 machine code. It’s apparently just a random hexdump from an Apple II’s memory. At other times, there’s also 6502 assembly code on screen which includes various programmer comments still intact. There’s even some code cribbed from the Apple II DOS 3.3 RAM Disk driver.

It’s neat to see someone actually track down the background of these classic graphics. Hacking and computers are usually portrayed in a fairly unrealistic way in movies, and it’s no different in The Terminator (1984). Still, that doesn’t mean the movies aren’t fun!

NVIDIA Jetson Powers Real-Time Iron Man HUD

May 4, 2023 by 15 Comments

If you could recreate any of the capabilities of Tony Stark’s Iron Man suit in real life, it would probably be the ability to fly, the super strength, or maybe even the palm-mounted lasers that can cut through whatever obstacle is in your path. But let’s be real, all that stuff is way too hard to try and pull off. Plus you’ll probably just end up accidentally killing yourself in the backyard.

But judging by the videos he’s been posting, [Kris Kersey] is doing one hell of a job creating a functional heads-up display (HUD) similar to the one Tony uses in the films. He’s even building it into a 3D printed Iron Man helmet, with the NVIDIA Jetson board that’s powering the show inside a chest-mounted “Arc Reactor”. He goes into a bit more detail about the project and his goals in an interview recently published on NVIDIA’s own blog. Continue reading “NVIDIA Jetson Powers Real-Time Iron Man HUD” →

HUD-Like Clock Is A Transparent Time Display

December 14, 2022 by 13 Comments

While we have all types of displays these days, there’s something special about those that appear to float in the air. This HUD clock from [Kiwi Bushwalker] is one such example.

The build relies on four 8×8 LED matrixes to display the four digits that make up the time, run by the MAX7219 driver chip. However, the LEDs aren’t viewed directly — that would be too simple. Instead, the matrixes shoot their light up at an angle towards a tilted piece of clear acrylic. This creates a “heads-up display” look where the numbers appear to float in the air.  The clock gets accurate time from an NTP time server over WiFi, thanks to the ESP32 microcontroller that runs the show.

It’s a straightforward clock build in many ways, but we particularly like the use of the heads-up display technique. It’s almost surprising we don’t see these projects more often, for things like car dashboard displays or targeting womp rats in a T-16 landspeeder. If you’ve been whipping up your own HUD projects, don’t hesitate to notify the tipsline!

Garmin HUD Got Discontinued, But Not Trashed

October 30, 2022 by 8 Comments

The Garmin HUD+ was a small Bluetooth device intended for the dashboard of a car, meant to be used as a GPS heads-up display for data from Garmin smartphone apps. It used a bright VFD (vacuum fluorescent display) which was viewed through a clear reflector, and displayed GPS information and directions. It was discontinued in 2015, but [Doz] was fond of his and used it happily until a phone upgrade meant it no longer worked. Was it destined for a landfill? Not if he had anything to say about it!

The first thing [Doz] tried was using an alternate Android app, but since it also didn’t work, it was time to sit back and reflect on the scope of the issue. In [Doz]’s case, he really only wanted some basic meaningful data displayed, and decided he could do away with the phone altogether if he had the right hardware.

Arduino Car HUD Does The Job

June 3, 2020 by 17 Comments

Many cars these days come with a basic Heads Up Display, or HUD. Typically, these display speed, though some also throw in a tachometer or navigational graphics too. Of course, if your car doesn’t have one of these stock, hacking in your own is always an option.

[PowerBroker2] developed this HUD in a somewhat circuitous way, but it’s effective nonetheless. An ELM327 Bluetooth OBD-II reader is hooked up to the car, collecting data on speed and RPM. This data is passed to an ESP-32 and Teensy 3.5. From reading the code, it appears the Teensy is responsible for logging data from the CAN bus on an SD card, and running a small OLED display. The ESP32 is then charged with running the LED display that actually forms the HUD. It’s then combined with a 3D-printed housing, some plexiglass, and reflective windshield film to complete the effect.

It’s a build that probably packs in more hardware than is strictly needed to get the job done, but it does indeed get the job done. Other builds we’ve seen use LED strips as a quick and tidy way to get the job done. Video after the break. Continue reading “Arduino Car HUD Does The Job” →

Iron Man Mask With A HUD!

March 25, 2018 by 12 Comments

At some point, a child will inevitably dream of being a superhero. Not all children get the chance to see that dream made manifest, but a few take that destiny into their own hands. Redditor [Lord_of_Bone] — seizing at that goal — has built himself an Iron Man mask with an integrated HUD!

Relying on a conceptually similar project he’d previously built, much of the code was rehashed for this ‘Mark II’ version. Pieces of a smartphone holo pyramid act as projection surfaces — using a lens to focus the image to be viewed at such close distances — and a pair of OLED screens displaying the information. It’s a happy bonus that the lack of backlight results in only the text showing in the user’s field of view.

Instead of speaking with J.A.R.V.I.S., [Lord_of_Bone] is using a Raspberry Pi Zero W as the mask’s brain. Working past some I2C troubles between the OLED screens and an Enviro pHat required a whipped-up veroboard and a bit of hardware hacking. Cramming everything into the mask was no easy task — using Blutack and Sugru to bind them in the limited space — but the pHat had to be surface-mounted in the open anyways for atmospheric and light data.

Hackaday Prize Entry: Visioneer Sensor HUD

September 28, 2017 by 4 Comments

Only about two percent of the blind or visually impaired work with guide animals and assistive canes have their own limitations. There are wearable devices out there that take sensor data and turn the world into something a visually impaired person can understand, but these are expensive. The Visioneer is a wearable device that was intended as a sensor package for the benefit of visually impaired persons. The key feature: it’s really inexpensive.

The Visioneer consists of a pair of sunglasses, two cameras, sensors, a Pi Zero, and bone conduction transducers for audio and vibration feedback. The Pi listens to a 3-axis accelerometer and gyroscope, a laser proximity sensor for obstacle detection within 6.5ft, and a pair of NOIR cameras. This data is processed by neural nets and OpenCV, giving the wearer motion detection and object recognition. A 2200mA battery powers it all.

When the accelerometer determines that the person is walking, the software switches into obstacle avoidance mode. However, if the wearer is standing still, the Visioneer assumes you’re looking to interact with nearby objects, leveraging object recognition software and haptic/audio cues to relay the information. It’s a great device, and unlike most commercial versions of ‘glasses-based object detection’ devices, the BOM cost on this project is only about $100. Even if you double or triple that (as you should), that’s still almost an order of magnitude of cost reduction.
