Nine Digit Problem Solved In 2.2 ms The FPGA Way
Here’s the problem: The folks over at Programmable Gatorade wanted to take this classic math problem and put their Altera Cyclone IV FPGA board to use in solving it. The design uses the board’s 50MHz clock and finds the solution in approximately 2.2ms. There are three main components to the design: a module to calculate…

DIY “Via Press” An Elegant Solution To An Irritating Problem
When designing double-sided PCBs, Retromaster kept running into the same annoying problem: how in the world do I set my vias without them sticking out too much? A via must protrude from the board only very little, otherwise it cannot be placed under an IC. So placing copper wire in the via hole and soldering both ends is…

HDMI Hacking – Great Information About Tapping Into HDMI
We recently got word of an intriguing hack that lets you bust into an HDMI cable to sniff out the HDMI protocols for interesting data such as control information and the HDCP security keys. Adam over at Aperture Labs put out a great article at his blog showing exactly how to do this. First of all, you’ll need…

VHDL SD Card Writer v1.0 For Papilio
Forum user Matt Ownby has put together some code to be able to write data at full speed (50 MHz) to an SD card, and was kind enough to share it with us! This is VHDL code for the Papillio One FPGA board that shows how to write to an SD card in a high-speed mode. Here’s the…

High Speed Data Transfer Between Two Papilios
Mike Field (hamster) of Hamsterworks has written a new tutorial on how to achieve a high-speed data transfer between two Papilio One 250k boards. The goal of the project was to achieve data transfer at 400 mbps, and Mike wound up exceeding the target by a pretty good margin. From Mike’s project description, The aim…

Sneak Peek – Build Arduino-Compatible SOCs With New Schematic Editor
Today we wanted to give you a sneak peek at a new SOC (System On Chip) schematic editor for Papilio that we are working on. The editor is a drag and drop system that makes it easy (even for beginners) to draw schematics even without necessarily having VHDL experience. Jack says, What we need is…

Genetic Algorithm AI Writes Self-Modifying/ Improving Programs
Kory Becker from Primary Objects has been experimenting with AIs capable of writing their own computer programs. The AIs Kory is using are called genetic algorithms. They function much the same as biological evolution, in that the programs they write get better and better with each generation. In other words, genetic algorithms are programmatic implementations…
