  • Build your own Mandelbrot Fractal Generator with FPGA

    Greetings FPGA lovers! Today’s post takes you into yet another interdisciplinary project that links pure mathematics, FPGA and VHDL to build something beautiful! The Mandelbrot set is a series of complex numbers that tend to infinity when operated upon by a special operator. These numbers when grouped together create a beautiful image sequence which might…

  • How To Control What You See On A Screen in Two Hours and For Less Than $25!

    Imagine how cool it would be to control what appears on your screen and at a bargain price, just using your FPGA (yes! Your Papilio!) and some other easy-to-get components. All you need is read today´s article (and buy the tiny things of course). This how-to post is one of those which are written thinking…

  • Controlling the output of a Papilio Pro with the wheel of a mouse

    https://youtu.be/N8pwx4Y7E30 There are tons of ways of creating a home-made microcontroller. Today we present a very detailed tutorial on how to achieve this using the rotary encoder from the scroll button of a mouse. This is part 5 of a series. The goal here is to achieve a constant frequency signal at the output of…

  • Cool QR Code Clock On Graphical LCD

    Sometimes its good to see what other people are up to on their projects. It can serve to spark an idea for your own designs, and this one here is just plain cool. This QR code clock is displayed on a graphical LCD screen, and is totally indecipherable just to look at. You have to…

  • New Update For Hamster’s I3C2 Programmable I2C Controller

    Mike Field/Hamster has got an important update to the last article we posted (Intelligent I2C Controller Project) that we thought we’d share. You can view the full rundown in two parts over at All Programmable Planet, and there are also project resources via Hamsterworks and on the Gadget Factory forums. Check out what’s new since…

  • Intelligent I2C Controller Project

    The Hamster man, Mike Field has a new project up that is an intelligent I2C controller. It is a small programmable controller that makes it quick and easy to talk to I2C devices. The controller has a single I2C bus, 16 binary inputs, 16 binary outputs and writes I2C data to 32 8-bit registers. The…
