Anyone who follows Turbo's Aquatics on Facebook might have already seen this... Update! I just got word that my new Metal-Core PCBs (LED boards and custom driver boards) should be done next week, then they're off to Steve's LEDs for component mounting. I've been out of these for over a month now and the waiting list is piling up, but the wait will soon be over...at least for those at the top of the list! The new LED board uses Hyper-Violets instead of Royal Blues, and no more pin-jumpers, this board can run run several different ways: 1) You can use a stock dimmable or non-dimmable driver (like a Meanwell LPC or ELN, etc) 2) You can use my new custom 3-channel driver developed in conjunction with Steve's LEDs, either stand-alone, or in conjunction with a controller with PWM ouput (like the Typhoon, which I will be carrying) The driver board is another big jump for the world of Algae Scrubbers. I put a lot of time and thought into designing this board so that it truly has the capability to maximize algae growth throughout all stages of growth. This is also one of the reasons why I haven't had any scrubbers available for a while...it took longer than expected to work out all the details, but that also means that this board is designed to be highly flexible. The custom driver allow you to control 2 red channels and one violet channel on 2 LED boards. The driver has on-board SMD (surface mounted device) potentiometers, a port for an external potentiometer (dimming knob) and ports for PWM dimming input. Both the external dimmer and the controller are powered from the driver board, so you only need one power connection. The way I designed the driver board, you can do things like this: - set the SMD to be the "high" current limit, then the manual knob will dim through the range from zero to the SMD setting. - set the SMD and forget it (essentially the same as using a stock dimmable driver) - connect a Typhoon Controller (or another Arduino-based controller) and dim each channel separately on as many cycles as your driver can perform (hourly, daily, weekly, growth cycle, etc) - use Steve's Aquarium Controller Interface harness board to connect to your Apex or another device that has a 0-10V dimming output Having the ability to control the light cycle like this opens the door to many possibilities - most of them unexplored. This is just the first major announcement of the year. I'm working on a few more improvements that might just propel Algae Scrubbers to a whole new level. My eye is on making Algae Scrubbers easy for everyone to install, use and maintain. I've received some great feedback from some loyal customers, and I am a digital pac-rat, so I won't forget any of you that made suggestions that I end up incorporating.
