svnpropertylog v1.1.29 screenshot

svnpropertylog – A script which finds all revisions where a specific subversion property has changed

Purpose

The subversion application does not offer native support for identifying changes to subversion properties as easily as changes to files.

The purpose of this script is to allows a subversion user to find all revisions where a change to a specific property occurred. In other words, it’s a “show log for subversion properties“.

How to multiplex RC Transmitter switches into a single channel

How to multiplex RC Transmitter switches into a single channel

Introduction

In a personal project, I wanted to add 2 new devices to an existing quadcopter. The quadcopter was equipped with a 6-channel receiver meaning I only had 1 spare channel to control the 2 devices:
CH 1 : Throttle
CH 2 : Rudder
CH 3 : Ailerons
CH 4 : Elevator
CH 5 : Flight mode
CH 6 : ???
The following article explains how I manage to solve the issue: How can I control more than one device using a single channel.

Arduino RcReceiverSignal library

RcReceiverSignal: an arduino library for retrieving the RC Transmitter value from an RC Receiver pulse

Introduction

The following arduino library was written to use the findings found during the Mapping RC Transmitter PWM signal to actual transmitter values article. All results were wrapped into a library for ease of use.

The RcReceiverSignal is an arduino library that allows one to read a signal sent from a Remote Controlled (RC) receiver.

Arduino BitReader library

BitReader – An arduino library for reading & writing data as chunks of bits

Introduction

Here is another arduino library that I have written.

As a desktop developer, I am not used to have memory (or even CPU) requirements as most developers will not look at memory consumption as an arduino developer would. Memory & CPU is cheap. If your application is struggling to run on today’s computer, it will run smoothly in 1-2 years.

As most arduino developers have faced, the amount of memory available on embedded devices is pretty limited. Having a way to save bits or our precious memory is interesting.

BitReader is an arduino library that allows one to read or write data as chunks of bits.
