It supports multiple virtual systems - FTP/SFTP, SMB, NFS, HTTP, Amazon S3, Hadoop HDFS, Bonjour and can browse, create and uncompress ZIP, RAR, 7z, TAR, GZip, BZip2, ISO/NRG, AR/Deb and LST archives. Also trolCommander can wirk with Android devices filesystems.

trolCommander requires Java Runtime 8 (or highter).

Last version: 0.9.9

The best free file manager for Mac OS and not only


When you use your Mac, file browsing options are important. The default file browser for Mac OS is Finder. However, many Mac users find it to be lacking in a few essential features like dual window mode. Fortunately, there are many alternatives - paid and free. Among the free file managers can be noted Moroshka, Midnight commander and muCommander.

Bresenham's line algorithm for power control

Bresenham algoritm

When creating a microcontroller devices periodically there is a problem of regulation of some of the analog value, such as voltage at the IC pin, LED brightness, power, etc. In order to form an analog signal with a given amplitude at the pin of chip commonly used method of pulse-width modulation - PWM. The basis of the PWM output is on pin IC pulses with varying duty cycle.

Calculation of the tabular functions for microcontrollers

Calculation of the tabular functions for microcontrollers

When programming microcontrollers sometimes there is a problem of calculation of math functions. And despite the fact that the standard AVR GCC library includes support for float numbers and basic math calculations, in practice is not always possible to use these routines.

Two microcontroller regulators for fans

Two microcontroller regulators for fans

This device allows to reduce the noise from cooling fan. It turn off the fan or reduces the rotation speed depending on the temperature of the radiator. Also the device beeps when temperature exceeds a threshold. There are two variants of device for fans of different power.

The first variant is designed to control 12-volt computer fan, and has been fully implemented on the SMD-elements:

Mood Lamp on ATTiny13

Moodlamp on ATTINY13

Mood lamp is a LED RGB lamp that changes the color of light at random. There are a lot of mood lamps projects in the Internet and usually they use relatively "big" microcontrollers. I wanted to make a lamp based on simply ATTiny13 microcontroller.

The circuit of the device is very primitive and shown in the figure below:
