Electronic components sources

I often need to buy some electronic components.

Where to look for components, tools, information ?

Teirmilab - final building

Ok, time to close the project.
This article will be updated to track the progress.

tRPOf with Trinket - updated

This article is about a RPOf circuit for the Raspberry Pi using a Trinket, thus the name  tRPOf.
The main difference from previous ones, is that this project uses a standard Adafruit Trinket as microcontroller instead the MSP430 in order to use "off the shelf" components with less effort of programming and a LiPo charger/USB DC/DC converter..

Texas Instrument TI Programmer

Often during the week ends we love to visit antique malls and similar places, looking for something to adapt to other uses or just strange things.
Sometimes instead I found things that .. well, something I can not just leave there.

DIY fume extractor

A quick DIY fume extractor.
Breathing fumes when soldering is not exactly an healthy activity.
You can buy a fume extractor but often they are quite expensive.

Repairing a GoldStar microwave

My old microwave started to have a problem lately.

Sometime when turning ON the oven, only the light works, the blower and the magnetron remains turned OFF.

VPN - generate a new user key

This is just a quick way to remember how to generate a user key for openvpn.

Controlling a WS2812B LED

Just some brief notes about LED strips based on the WS2812B (for example this one).
The same LED is also used in the Adafruit circular ring LED (here a datasheet from Adafruit)

Technology changes

The market for embedded development is more and more complex and fast these days.
Every day there is some new platform popping up.
Is quite difficult to stay updated unless you have to do that for work.

A toroid tale

I'm a software developer, mainly in firmware for many years and still today I really love working on small board in C or assembly. I consider that a "real" programmer job.
Going down on the memory lane (pun intended :) ) it can explains maybe why.
