Рет қаралды 5,437
5 жыл бұрынInexpensive projector with a small, but extremely limiting issue. Not entirely sure what the actual model number of this projector is supposed to be, but UC46 seems to fit our findings.

Now, that's a bull of a cliffhanger! If I've ever seen one! *rofl* I mean, please, get that *darn* opto, quick! :-D I barely can stand it.. especially as I got a bunch of'em on my desk. Why can't we just beam one over, I wonder. Scotty, come on!

Hello, thanks for your greats videos! I have a problem with my UC40, the screen is fliped. The screen menu is grey, I can't reverse my screen.. Do you have the must recent fireware for this? Thanks a lot!

Can you explain what an "opto-coupler" does? Thanks Great videos!!

Opto-coupler comprises of an infrared led shining light onto a transistor. Shining light onto the transistor die has the same function as feeding a current into the base pin of said transistor. Often only the Collector and Emitter is brought out (like in this case of the 4 pin optocoupler) - The reason to use optocoupler is usually isolation - these can make an "electrical contact" in a circuit that is otherwise at a potential of several thousand of volts apart.
