A few years ago (4-5?) I bought a ZOPAN KZ1405 frequency generator, and after a few weeks of using it I noticed that the lack of digital readout is a real pain in the ass. Besides, , it is a really old piece of equipment and to get into spec it needs about 45 minutes to get “warm”, and stabilize itself. So I sat down and started drawing a draft of a small frequency counter. The idea was to create something relatively simple, just to orientate oneself in the real frequency on f-gen output.

I have a few ftdi serial devices in which the manufacturer has changed the standard ftdi chips product and vendor numbers to some custom values (you can check those values using the lsusb command, vendor and product ID are two numbers separated by a colon). Until recently this was not a big deal, because there was a way to pass the vendor and product id params to fdti_sio module during the loading with the use of modproble command, but since 3.12 kernel everything changes…

Today I want to show you my quick project (about 2h of work): it’s a desk lamp with a touch sensor as toggle (on/off) switch. Wherever you touch the lamp, it will toggle on/off. Take a look at my video below, and you will see what I’m talking about. ;)

Some time ago I wrote an article about using a rotary shaft encoder (Budujemy cyfrowy zasilacz – enkoder obrotowy w praktyce – sorry only polish version), but it was a very specific situation, in other words it wasn’t a very correct way there. So I decided to write, once again, about encoders and try to explain how to connect and handle it, in a correct way, with avr mcu (in the examples I am using ATmega8A-PU, but it should work on any other eg. ATmega32 or arduino compatible ATmega168/328).

In ubuntu 13.10 the ia32-libs package has been removed, and because of that installing any 32 bit app on 64 bit is not as simple as it was before. Below I will show you how I have handled this problem and how to install the adobe air runtime enviroment.
