The new network LED Dimmer from Opto 22 uses pulse width modulation technology (PWM) to control brightness from 0-100 percent for 9-30 to control VDC constant voltage LED lighting assemblies such as lamps, bulbs, strips, ropes and bars. It can also be used for other resistive-type loads. (Source: Opto 22)
Cabe, Very surprising that serial communications wouldn't be a topic that everyone would be exposed to. But I guess it is simple enough that young engineers can get up-to-speed on their own if they need to
In a lot of vehicles today, the interior lights dim as you prepare to drive, or when leave the vehicle and close the door. I do wonder if LEDs have been able to do that up tp now. This technology would be important for those applications, I would think.
Al, this is an interesting approach, and as you point out it is flexible and extensible. One thing it does bring to light (pun intended) is that controlling LEDs is much more complex than the systems they replace. On the other hand, with the electronics we have available now, it is not a problem to develop and integrate systems such as this.
MIT students modified a 3D printer to enable it to print more than one object and print on top of existing printed objects. All of this was made possible by modifying a Solidoodle with a height measuring laser.
