Not at all - but I am keeping mine with the screen facing down so the heat can escape.
If they are set down face up (which is the most intuitive thing to do...) the heat just pools under the LCD.
I am considering drilling holes in the front cover to help let heat out as I suspect most people will set them face up even if we tell them to set it face down.
Still working on ideas over here.
I sure would like to just populate the empty space on the PCB and then improve the efficiency of the cooling design. Even just a moth flapping its wings would make all the difference here....
Awesome would = 250mA - 500mA diode to send the power away in the form of photons
Awesome would = tiny surface mount pager motor with a counterweight that could work the energy away mechanically
Awesome would = 2W fan on every channel - self cooling power dissipation
Awesome would = tiny DC-DC that would take the 4.2V from one channel and funnel it back as 25.2V to the pack
Maybe Poly fuses can play a role here... resistors are linear but the poly fuses would allow more current to flow with better cooling
Maybe we could utilize the duty cycle with tiny little transformers
Ok - back to finding a clean way to dump power the good ol'fashioned american way
