Blog

All articles that do not qualify as “projects” were moved here. Blog should be a section that will contain only a sequence of articles similar to a diary: musings on various subjects not related to a specific “mainstream” project but mostly a collection of day to day topics that cross my mind or things that I do.

Scavenging for electronic parts

Not very often I have the occasion to salvage some good parts from throw–away devices. Two days ago I found an empty TV set carcass lying on the sidewalk with some pieces left. The rest was — probably — savagely ripped off for copper and some other metals. It’s a bit of shame to see […]

Spam stupidity

Cleaned my spam list in the blog today. I am constantly amazed by the stupidity of these bots. Just a rant. Have a great day.

Plans for 2013

Another year started. Been so busy in the past month that I was unable to articulate some thoughts on my plans for 2013. This helps bringing some structured approach and — having a tendency to do many things at a time — should provide some prioritization. First, I would deepen my knowledge. In programming, in electronics and […]

How to use XCode 4 Exception Breakpoints

I will probably write a longer article on exception handling in XCode, for now just a quickie: how to use XCode 4 exception breakpoints, use the breakpoint customization features and get useful information for debugging. Usually when the app is crashing, a lot of cryptical mumbo-jumbo is displayed in the console. You have to dig the […]

Stuff to read

Foam board drawer

More than a year ago I posted this. It was the beginning of this blog and the beginning of my personal space for hobbies and small DIY projects, a very crammed and tiny space that I have in my apartment. I cannot imagine how quickly time passed and how less and less available time I have for […]

JFET Circuit Analysis – great tutorials on YouTube

Looking for some detailed information about JFET circuit analysis, I ran today into three excellent videos posted by Bournemouth University. Already subscribed to them. The videos are part of Linear and Switching Circuits Series and target the following topics: Performing the DC JFET circuit analysis of a simple JFET self-bias amplifier (to find the circuit […]

Toshiba Satellite, L855

Several years ago I completely switch to Apple starting with an iPod and culminating, some months later, with an iMac, a 13″ MacBook and, finally, with a QuadCore i7 MacBook Pro. Still very happy with may MBP, and things got better and better with each OSX release. Now, with Mountain Lion cannot be more satisfied. […]

Redesigning the blog

I decided a need a new theme for this blog. Rolled my sleeves and started to work.

Custom-made drawer and shelf

A tiny workspace

Haven’t been online and active for some time. I was very busy accommodating a small workspace in the living room. I have some IKEA pieces of furniture that I did not want to modify extensively, but to adapt somehow for my small projects. I built a shelf and a custom drawer, now being almost done […]
