Easiest 3D Viewer for EAGLE PCB boards we’ve ever seen!

Alvie pointed us to this amazing new website that lets you drag and drop an EAGLE board file and view it in 3D. While there are other sites that have been around for a while do the same thing, this is the first site that lets you edit the components on the board with ease. We were able to make a fully populated 3D view in a matter of minutes with this tool! It usually takes over half an hour to do the same thing with the other tools we use. This is great if you want to show off your board or make a very clear view of your board for your board manufacturer’s.

Thanks for the great tip Alvie!

Remember Playing Cowboys With A “Hand” Gun? Now It´s a Video Game

shooter game

Thanks to the work developed by a group of students at Cornell University, all you would need to do is to paint the tip of your finger in Red. This is not to fake that you are shooting that much that your finger is burning. This is because their project is based on this color. Feel free to adapt it to you likes as it is all open source.

This article presents a thorough description of their work. Read it to learn how you can use the power of an FPGA´s parallel processing to build your own shooters game.

All you need is a video camera to capture the movement of your hand and then output the NTSC signal that is processed by the FPGA board (like a Papilio). Finally, the VGA controller will output the signal to the VGA monitor. Otherwise you wouldn´t know where to shoot!

Oh! And of course, you need to read this and thank the Cornell guys for their great work!

Sayonara baby!

Here is How The Dark Side Got Started With Their Robot Army!

Nowadays, you may be fed up of Star Wars jokes, baits and so on. I am sorry, I could not resist the temptation.

Anyway, this time, at least, was not a joke nor a lie. Today´s article brings the real truth to you. If you want to build your own robot, as simple as you want it to be, the first step should be to learn about controlling a DC motor! Now it does not sound as funny as watching the results achieved by the Dark Side´s Army. You may be wrong because this tutorial is everything but boring.

Very easy to read, this step-by-step article presents all you need to learn to properly understand how to control a DC motor just with your FPGA (yes you can use your Papilio). All you need is outlined and well explained (the code needed is given…). There are also some easy to understand physics explanations so you will get to understand the real ins of this project.

Do not miss this tutorial and be ready to get hired by The Dark Side!

Ever dreamt of playing Tetris on a wall of your room? Now it´s possible!

Remember all those days looking at a small screen following the tiny cubes falling down quicker and quicker…? Never again! Those days are gone and for good. We are not saying that you no longer have to play Tetris, just that you don´t have to do it on a small screen.

Today´s tutorial will teach you how to build your own Giant Tetris. You read it right, giant. The one used in the article is 6 ft tall, but you can adapt it to your needs…or just to the height of your ceiling.

All you need is a grid of RGB LEDs and a Papilio FPGA board, follow each step of this thorough tutorial and build your own Giant Tetris!

Flying high with Zynq

Open source enthusiast? Drone enthusiast as well? FPGA fan? Rejoice! The first Unmanned Air Vehicule combining all those technologies has recently been announced. It’s powered by a Xilinx Zynq processor running ArduPilot, and its source code is planned to be released. The team behind the project used a DJI F550 airframe and plans to test on more hardware. One of team founders says that using the FPGA part of the Zynq allows an easier real time processing, especially computationally intensive tasks. Before we see a video of the flight, we’re happy to learn that the Zynq board runs on Linux!

Fitting 3D prints on Eagle boards


Using a electronic design to mesh your mechanical design can be quite a difficult task. 3D printers come to the rescue to facilitate this process, especially when using an Eagle to design a PCB.

In the following post, the designer used several LEDs to build a clock which worked fine but there was a slight light leakage around his custom made 7 segment numbers. More information on this project in the link below.

Spit out VGA with non-programmable logic chips

Bitbanging a VGA can be a tough task due to the timing requirements. Nevertheless Sven gave it a go and not only he bitbanged a VGA on an arduino, but he managed to configured an array of 7400 logic chips to output a VGA signal.

Consisting of two parts, his project first consisted in outputting a VGA signal on a monitor then talking about adding circuitry to take care of frame counting, geometry and color.

A simulator was first used to plan out the graphics, then a 7400 chip configuration was designed for the display.
