Introducing CERN's Open Hardware Repository
Javier D. Garcia-Lasheras 6/17/2013 15 comments
The Open Hardware Repository (OHR) has proven the feasibility of its open-but-commercial vision. More than 100 projects are hosted by the OHR, which is promoted by eleven research institutes and sixteen commercial companies.
Ask Max: How Do Mirrors Work?
Max Maxfield 6/15/2013 17 comments
If you ask most people if they can explain how mirrors work, their knee-jerk reaction will be, "Yes, of course!" After reading this blog they may change their minds...
Ask Max: High-Speed Serial Interconnect
Max Maxfield 6/13/2013 9 comments
One alternative to parallel interconnect in the form of busses is to use a serial interconnect setup. This typically involves a special transceiver block inside the device.
Implementing a PWM on the Opal Kelly Board
Tom Burke 6/11/2013 20 comments
Pulse-width modulation (PWM) is used for all sorts of things, including servo motor control, DC motor control, AC induction motor control, and the voltage output control on switching voltage regulators.

Using Verilog to Interface to a GUI
Tom Burke 6/4/2013 6 comments
In this column, Tom revisits his original schematic projects and recreates them in pure Verilog code, thereby proving that sometimes old dawgs can be taught new tricks.
A Chess-Playing FPGA: The First Testbench!
Warren Miller 5/30/2013 14 comments
Is the low-level module testbench described here sufficient, or is there a better approach? Should a self-test testbench be used? How important are concepts like portability, ease of understanding, and ability to make modifications?
Discovering FPGAs: Robot + ZedBoard + Linux, Part 2
Duane Benson 5/27/2013 7 comments
Duane Benson has decided the FPGA fabric in the Zynq All Programmable SoC will handle the short-term obstacle avoidance navigation in real-time. The Linux OS will handle longer-scope activities like point-to-point navigation.
What Does an AND Gate Taste Like?
Max Maxfield 5/27/2013 49 comments
I know someone who perceives different colors when looking at black-and-white gate-level schematic diagrams. Now I'm looking for someone who perceives logic gates as having "taste."
Ask Max: Primary Colors, Part 2
Max Maxfield 5/24/2013 24 comments
We consider complementary versus analogous colors and the meaning of terms like shade, tint, and hue. We also introduce the concept of psychological primary colors.
The Microprocessor (R)evolution
Sven Andersson 5/24/2013 21 comments
This "retrospective" blog describes how I became involved in testing microprocessors in 1976, and how microprocessors have influenced my professional work for many years...
Ask Max: Primary Colors, Part 1
Max Maxfield 5/23/2013 23 comments
The appellation "primary colors" refers to a small collection of colors that can be combined to form a range of additional colors, but which "small collection of colors" should we use as our primaries?
FPGAs — What's Left to Integrate?
William Murray 5/23/2013 21 comments
Today's FPGAs already integrate a substantial amount of "stuff" (MCU cores, programmable fabric, on-chip memory, etc.), so what's left to integrate and why is this being left for the future?
A Word to the Wise
Max Maxfield 5/17/2013 32 comments
Would you class these as adages, aphorisms, axioms, dictums, epigrams, maxims, precepts, saws, truisms, or... well, what?
Adam Powers Up His Zynq ZedBoard, Part 7
Adam Taylor 5/17/2013 14 comments
Here we discover how to use the XADC (Xilinx Analog-to-Digital Convertor) in the Zynq All Programmable SoC to read the chip's internal temperature and voltage parameters and output them over an RS-232 link.

Here's an image of the week and a joke of the week. Also, this week's live online chat takes place Thursday, June 20, at 1:00 p.m. ET (10:00 a.m. PT).
Duane is now poised to use his I2C interface to send commands to the driver boards controlling his robot avatar's motors.
The Open Hardware Repository (OHR) has proven the feasibility of its open-but-commercial vision. More than 100 projects are hosted by the OHR, which is promoted by eleven research institutes and sixteen commercial companies.

In this blog we consider the attack logic for a single square; this can then be replicated to create the entire 64-square chess board.
