Better range for LivingColors shield.

Some LivingColors shield users have reported that they would like to have a longer range. In the past I have been looking at hardware solutions for this without much success.

One of my customers has found a much simpler solution : adjust the power settings in the CC2500 configuration.

In the file LivingColors.cpp

The lines :

De value 0xA9 can be changed to 0xBB (-2 dB output power), 0xFE (0 dB output power) or 0xFF (+1 dB output power)

The registers of the CC2500 are described in the datasheet page 47, table 31.

The updated library can be found here :


Alpha Clock Five

In return for helping out at Makerfaire Eindhoven, Pieter from gave me a Alpha Clock Five kit from Evil Mad Scientist.

The kit is very well documented (schematic and sourcecode), uses only though hole components and is easy to assemble.

Aside from the Atmel and Chronodot stuff it uses two interesting IC’s : Macroblock MBI5027 and Macroblock MBI5168

Another nice thing about the Alpha Clock Five is the Serial protocol that allow you to control all aspects of the clock.

The software is really polished, no flickering display, nice gradient while dimming, user definable characters. The only thing missing you could possibly want is different intensities per segment.
