R48 Battery Life Improved

After looking through the firmware very closely, I figured out a way to reduce power consumption of R48 via firmware tweaking. (Aggressive use of CPU “idle” mode while waiting for PWM pulse to output, etc.)

I managed to reduce the power consumption up to 43%. In my tests the batteries are lasting 50% or more longer!

All R48 will be shipped with the new, improved firmware as of today. If you already have R48, please send in for free upgrade.

Aurora 9×18 and 18×18 Firmware Update

I discovered a bug that prevents start up at the power on. The condition is relatively rare, but if your Aurora 9×18 mk2 or Aurora 18×18 is suffering from occasional lookup at the power up, please reprogram the PIC with the updated firmware.

This firmware (version 1.4) is also revised to keep the speed change setting in the EEPROM (note: speed adjustment is only possible via IR remote), so that your set speed will be restored after power off/on.

Please let me know if there are any issues with this updated version.

- Aurora 9xx18 mk2 firmware: aurora9x18mk2-1.4.hex

- Aurora 18×18 firmware: aurora18x18-rev2d-v1.4.hex

Firmware Updates to the New Auroras

Aurora 9×18 mk2 and Aurora 18×18 firmware has been revised to detect the Audio Interface connection at the start up. The Aurora’s will check to see if the Audio Interface is connected to them, and disable the color organ modes (there are two). Which means you don’t have to go through two empty program modes when pushing the button to change modes without the Audio Interface connected.
