Working on my Logic Analyzer project, I wanted to setup a combined target structure in XCode, to have the complete E2E scenario built, from μC firmware to the cocoa libraries and application code. This means adding custom targets for μC build and upload. Well, as a short reminder, for now I am using a simple Arduino […]
Logic Analyzer!
…and not only software (maybe). OK, to keep things short, I got tired by limitations of my Saleae logic analyzer, especially on the software side so I decided to build one. This is my new project: a DIY logic analyzer that I will hopefully use to better extent in my other projects. First results promising. […]
Analog Devices – Currents Monthly, May 2012 issue
I love organizations that know how to share their know-how. Analog Devices is one of them.
Understanding Power MOSFET data sheet parameters
Fabulous piece of literature from NXP (here’s the link to a cool pdf). Nothing beats a well written material. So it seems that I have some very interesting thing to do this evening: printing this and have a good read. This comes on perfect timing for my MOSFET dummy load project ! Quoting from NXP’s material: […]
NSOutlineView — Inside Out
This is the first part of a series I intend to maintain on NSOutlineView. Some NSOutlineView basics and a very simple example.
Going Low Level
Some time ago I have on boarded on a very ambitious project that I though could be overkill, nevertheless I have persevered in my ambition to prove it is doable. However, as I needed to dig a bit into Assembly language, I have gathered some resources I thought it might be useful to share here.
Dummy Load Prototype – 2
Next steps for my dummy load prototype based on IRF830 N-Channel MOSFET, and a LM328 plus a multi turn pot.
OS X Lion, Safari, Activity Window and downloads
Previous versions of OSX had a very handy shortcut for downloading an item from activity window. How to do it in Lion ?

Multisim Circuit Explorer
Today’s goodie is an iPad app. A cool iPad app, designed for iPad not “iPad compatible”. It is from National Instruments: Multisim Circuit Explorer.
Weller WD 1000M Review
There are good tools and poor tools. Weller WD 1000 M is a state-of-art quality instrument that looks good, feels good, has a plethora of gimmicks and is a pleasure to work with. Let’s find out some more about my new soldering station.
MAX17058, MAX17059: 1-Cell/2-Cell Li+ ModelGauge ICs
The MAX17058/MAX17059 ICs are tiny fuel gauges for lithium-ion (Li+) batteries in handheld and portable equipment. The MAX17058 operates with a single Li+ cell and the MAX17059 with two Li+ cells in series…
Step by Step Measurement Handbook for Power MOSFET
A customized Application Test Library is created for testing the specifications introduced in this measurement handbook. They can be downloaded from the Agilent web site.
RFM12B Command Calculator for Mac
Inspired by this project for RFMB12 and needing a similar one for my Mac, I started to build one myself: Next – a version for iPad. Stay tuned. 😉
Agilent InfiniiVision 2000 X-Series Oscilloscopes Programmer’s Guide
Keysight’sAgilent’s InfiniiVision 2000 X-Series Oscilloscopes Programmer’s Guide is highly recommended for anyone interested in remotely controlling KeysightAgilent InfiniiVision 2000 X-Series Oscilloscopes. Via back USB slot. For example: Unfortunately, the [remote] control is limited only to Win PCs. AFAIK. Have to write a review soon about the cool KeysightAgilent Connection Expert, the client app installed together with the KeysightAgilent […]
Breakout board for RFM12B prototypes
Today I started to complete the design of the RF12B Breakout Board for various prototyping.
OpAmps for Everyone
A very thorough and useful reference produced by Ron Mancini at Texas Instruments. A must read for anyone takes OpAmps seriously: “OpAmps for Everyone”
FTP in Mac OS X Lion
With the release of their latest OS, Lion, Apple dropped support for FTP activation via System Preferences → Sharing. As all my wordpress developments are tested locally on a MacBook Pro, I needed to have a way to use FTP for remote plugin installation or system upgrades. It seems that even if FTP activation is […]
Finally arrived !
I just got it few days ago, a superb brand new Agilent 2002A Digital Storage Oscilloscope. Needless to say that I am absolutely thrilled by this 2G/s 70Mhz baby. It is a perfect addition for my electronics projects. Now I am playing with it, much to discover in the documentation. It comes with a CD […]
Keyboard shortcuts in XCode 4
First things first. Let’s present the navigator shortcuts. The Workspace Window has the following for areas: Opened with all areas active: Pressing cmd + 0 hides Project Navigator (left area): Pressing opt + cmd + 0 hides Utilities Area (right area): Pressing shift + cmd + Y hides Debug Area (bottom area). Always useful to […]
How to convert a mutable array to an immutable array
Really, how do you do this quickly ? Find here.
How to convert an immutable array to a mutable array
Part II of the mutable transformation “saga”. Find here how to quickly convert from immutable to mutable arrays.
How to create Arduino brush for Syntax Highlighter
For my Arduino lessons I needed to add WordPress support for Arduino syntax highlighting. A custom brush for SyntaxHighlighter plugin that would format and color my Arduino syntax similar to the application (see here an example). This is what I did.
Globals and Singletons
My preferred approach to creation and maintaing global variables/ constants is by singletons and singleton instance[s]. Not only is an elegant method that adds compliance to a very important Cocoa design pattern, but also provides you a lot of flexibility.
Code for Weather Station prototype
I took some steps in learning the capabilities of Arduino Platforms. Below is the code of my Bluetooth-enabled temperature reader with OS X integration.
