One Guy’s Endeavor Into Grading Microamps & Milliamps At A 3 MHz Bandwidth
Recently I needed to actually “see” a current waveform in the 100 uA to 5 mA range with at least a couple MHz bandwidth. This extremely expensive probe would have been perfect, but instead I built something similar for about $30 using the amazing Analog Devices AD8428 amplifier. Rather than buying an extremely costly o-scope…

BeagleBone Black Gaming Cape Project
We had a chance to meet and greet with the guys responsible for manufacturing the BeagleBone Linux platform back in May at Design West 2013. Turns out, the platform is continuing to pick up steam, and is one of the boards that Texas Instruments’ 2013 Design Challenge is supporting and accepting design entries on. We’re…

64-bit ISE Navigator Not Working On Windows 8? Here’s A Fix!
Hamster recently tipped us to a working fix for file dialog crashes in Xilinx ISE x64 on Windows 8. This issue has really been a thorn in the side for a lot of users, so it’s great to have this info! Rename libPortability.dll to libPortability.dll.orig, and copy libPortabilityNOSH.dll to libPortability.dll. Do this in: C:\Xilinx\14.5\ISE_DS\ISE\lib\nt64 C:\Xilinx\14.5\ISE_DS\common\lib\nt64…

Bitcoin Mining Rig With R-Pi & DE0-Nano FPGA
Here’s an interesting Bitcoin mining rig consisting of both a Raspberry Pi and an Altera DE0-Nano FPGA board. The guys over at Design Spark decided to give this Bitcoin mining thing a try, and their project page details their efforts. You’ll find the links below for those who would be interested to give it a…

FPGA Platformer Game Written Entirely In VHDL
FPGA enthusiast and nostalgic gamer Ben created a 1980s-style side-scrolling platformer game (think Super Mario Bros.) entirely in VHDL. Hence there is no microprocessor present. Ben’s game was originally written to run on an Altera dev board, and some other hardware. The hardware consists of: •A single FPGA •Power and clock circuitry •A controller, which…

Mains Hum Filter Using Papilio/ Logic Start
Hamster has a new project up over at his Hamsterworks site, and he’s got code running both for the Papilio/ Logic Start combination, and for the Arduino. In this project, he has created a filter that can filter out commonly encountered “mains hum” frequencies up to the Nyquist limit of half the sample rate for…
