If you’re working with a CGA, EGA, or RGB gaming system this inexpensive board does a great job of converting the signal to VGA so that you can play using a modern display. But what if you have a SCART connector as an output? That’s the situation in which [EverestX] found himself so he hacked [...]

[Jordan] writes in to show us a project he has been working on called MbedConsole. Living up its name [Jordan] has managed to run a 640×480 VGA output, PS/2 port and console all from the mbed itself. We really mean from an mbed only; no extra hardware is required aside from a few resistors and [...]

[Quinn Dunki] just moved to a new work space and had to pack up her homebrew computer project — called Veronica — in the process. She just unboxed it again and decided now was a good time to fortify the VGA display hardware. It wasn’t in the greatest of shape, since everything for the initial [...]

It’s fairly easy to create VGA with an FPGA using a simple R/2R DAC. As [Mike] points out, this requires a lot of IO pins, and many development boards only support 8 bit VGA. Analog VGA is being replaced with DVI-D and HDMI on many devices nowadays, so it would be nice to port projects from [...]

[Achu Wilson's] latest creation is a VGA message board which is written to via SMS text messages. This doesn’t sound too interesting at first, until you find out he’s doing this with a microcontroller rather than a PC. All of the complexity is in the code that drives the VGA. He managed to do it [...]

[Alessandro] sent us a link to his post about a PRU software VGA rasterizer. It’s not the easiest read, but we think it’s worth your time. The gist of his background information is that back when his company was developing for an ARM9 processor he wanted to test his mettle with the coprocessor chips. The first [...]

[sspence] found himself in need of a way to push the data from his digital micrometer to a VGA panel for easy display. His micrometer had a data port, so he figured he could plug it into a micro controller and have that push data to a VGA. The micrometer spits out a 52 character [...]

[Fernando] is working on creating a game at home, with live scoring displayed on a large LCD TV. He’s keeping mum as to what the game entails, but he was more than happy to spill the details on how he planned to use the television as a wireless scoreboard. The writeup is the first part [...]

[Nathan] got his hands on a chipKIT Uno32 development board and wrote a Pong sketch that you can play with a VGA monitor. We love the hardware that makes this feel very much like the classic. It uses a collection of resistor-based digital to analog converters to generate the color signals for the VGA protocol. [...]

[devb] has been playing around with XESS FPGA boards for ages, and as long as he can remember, they have had built-in VGA interfaces. His newest acquisition, a XuLA FPGA board, doesn’t have any external parts or ports aside from a USB connector. He needed to get video output from the board, so he decided [...]

The team at Leaf Labs just released a new library to demonstrate the VGA capabilities of their Maple dev board. Although it’s only a 16 by 18 pixel image, it shows a lot of development over past video implementations on the Maple. The Maple is a great little Ardunio-compatible board with a strangely familiar IDE. [...]

Recently on our Hack A Day forums a member asked about getting some VGA testers made in our “Request and Commissions” forum for a charity called the World Computer Exchange, who take old office PC’s and freshens them up to be used by children in developing countries for their education. I sort of wanted to [...]

If you’ve got some favorite electronic device that includes an SD card slot but doesn’t have a video out port you may be able to push VGA signals through the card reader conductors. That’s exactly what’s going on above with the Ben NanoNote, a sub-$100 Linux device which we’ve seen using its SD card slot as [...]

It seems like all the cool kids are leaving the 8-bit hobby microcontrollers in the parts bin and playing with more advanced parts like Complex Programmable Logic Devices. [Chris] is no exception to the trend, and set out to generate his own VGA signal using one of the beefy semiconductors. It seems that he’s using [...]

[ViDAR] was looking for a project to keep him occupied and settled on creating a VGA converter for his Game Boy. He had some difficulty finding pinouts for the LCD and CPU but working with what was known, and an oscilloscope, he found the necessary signal. Tap into just a few lines using those thin [...]

[Lucidscience] is back again, this time showing us how to push data to a VGA monitor from your AVR project.  It turns out that it is pretty simple, requiring only n open port and a few resistors and diodes. Well, it is that simple for the most basic version which gives you 56×60 pixels. Of [...]
