Linux Gizmos

morreale Saturday 19 of July, 2014
LinuxGizmos.com provides news and information on Linux in embedded and mobile applications. The site shows a whole bunch of neat SBC and devices that run Linux or are Linux compatible. I have a Linksys WRT54G router and it turns out that there is a openWRT project for a number of SBC like the ALS Atheros Module and Arduino.

morreale Monday 09 of June, 2014
NGSPICE has released CUSPCIE for the CUDA platform and requires video cards with the Fermi or newer architecture. CUSPICE is expected to speed model evaluation by a factor of three and is based Berkeley's SPICE3F5.

Component Modeling and measurement short course

morreale Thursday 03 of April, 2014
Agilent Technologies now Keysight Technologies hosted a short course covering
  • Component modeling and measurement,
  • Circuit design and analysis, and
  • System modeling
on April 2, 2014. The course was taught by
  • Venkatesh Balasubramanian from Maury Microwave Corp
  • Roberto Tiniti from Agilent Technologies
  • Murthy Upmaka from Agilent Technologies
  • Richard Hoft from Agilent Technologies
and covered five topics including
  • Pulsed IV/RF Measurements for compact model extraction
  • Amplifier Design Flow
  • VNA and NVNA Load Pull for Model Validation
  • Amplifier Design in ADA
  • Innovation in Nonlinear Measurements and Simulation using X-Parameters
This was a great short course. The instructors lead you trough the process of amplifier design with model extraction, test, verification using a PNA, PNA-X, and augmented PNAs for nonlinear model extraction. The introduction to x-parameters was well done and is a powerful extension to s-parameters.

A simple Forth development board

morreale Wednesday 16 of October, 2013
Hack a Day has posted an article on A simple Forth development board. Leon Nathaniel Maurer created the board and a floating point extension to Forth. The board is available for purchase and the components cost under $15. Forth is an interpreted threaded linked list language and really great for debugging hardware as you can build words in real time to test hardware.
