Unlike most old consoles, the Vectrex is unique for having a vector-based display. This gives it a very different look to most of its contemporaries, and necessitated a built-in display, as regular televisions aren’t built to take vector signals. Not one to be limited to the stock screen size, [Arcade Jason] decided the Vectrex needed a projection upgrade, and built exactly that.
The build relies on a lens that [Jason] salvaged from an old rear-projection TV. These units used CRTs with big lenses which projected the image onto a screen. That’s precisely what is happening here, with a vector display …read more
The only question we have about [mitxela]’s DIY vector graphics game console is: Why did he wait five years to tell the world about it?
Judging by the projects we’ve seen before, from his tiny LED earrings to cramming a MIDI synthesizer into both a DIN plug and later a USB plug, [mitxela] likes a challenge. And while those projects were underway, the game console you’ll see in the video below was sitting on the shelf, hidden away from the world. That’s a shame, because this is quite a build.
Using a CRT oscilloscope in X-Y mode as a vector …read more
Asteroids is one of the classic games of the early arcade era. Launched in 1979 by Atari, it relied upon using an XY vector monitor to deliver crisp graphics for its space-based gameplay. One of the limitations of the original arcade games was that the game was only rendered in a single colour, white. Over 30 years later, [Arcade Jason] decided to see what it would take to build a color Asteroids machine.
The hack relies on the fact that the original game used a four-bit resistor ladder DAC to draw vectors in different intensity levels. Through some ingeniously simple …read more
We’ve all had the heartbreak of ordering something online, only to have it arrive in less than mint condition. Such are the risks of plying the global marketplace, only more so for used gear, which seems to be a special target for the wrath of sadistic custom agents and package handlers all along the supply chain.
This cruel fate befell a vintage Vectrex game console ordered by [Senile Data Systems]; the case was cracked and the CRT was an imploded mass of shards. Disappointing, to say the least, but not fatal, as he was able to make a working console …read more
There is a huge variety of hardware out there with a font of some form or other baked into the ROM. If it’s got a display it needs a font, and invariably that font is stored as a raster. Finding these fonts is trivial – dump the ROM, render it as a bitmap, and voilà – there’s your font. However, what if you’re trying to dump the font from a vintage Apple 410 Color Plotter? It’s stored in a vector format, and your job just got a whole lot harder.
The problem with a vector font is that the letters …read more
[bitluni] got a brand new scope, and he couldn’t be happier. No, really — check the video below; he’s really happy. And to celebrate, he turned his scope into a vector display using an ESP32.
Using a scope in X-Y mode is nothing new, of course. The technique is used to display everything from Lissajous patterns from an SDR to bouncing balls from an analog computer. Taken on as more of an exercise to learn how to use his new tool than a practical project, [bitluni]’s project starts by using two DACs on an ESP32 to create simple Lissajous patterns …read more
The Vectrex is in no way the most popular console of all time, but it is one of the more unique. Eschewing typical raster-based rendering, it instead relies on a vector-based display. Since the average home television of the era would be completely unable to display such signals, the Vectrex had its screen built in. This got [Arcade Jason] wondering – would it be possible to hook the Vectrex up to a bigger screen?
First, a suitable monitor had to be found. The 19V2000 turned out to be a good candidate – much larger at 19 inches, and found in …read more
Part lightshow, part art piece, part exploratory technology, Light Barrier (third edition) by South Korean duo [Kimchi and Chips] crafts a visual and aural experience of ephemeral light structures using projectors, mirrors, and a light fog.
Presently installed at the ACT Center of Asia Culture Complex in Gwangju, South Korea, Light Barrier co-ordinates eight projectors, directing their light onto a concave cluster of 630 mirrors. As a result, an astounding 16 million ‘pixel beams’ of refocused light simulate shapes above the array. The array itself was designed in simulation using an algorithm which — with subtle adjustments to each mirror …read more
