USB IR Toy prototype testing
Testing a USB IR Toy update, the infrared light is visible to the camera.
This design uses three LEDs. Two 50degree wide-angle LEDs on the side, and a 25 degree narrow beam LED in the center.
Total current is 100mA, could be pushed to 200mA. Using 3 LEDs let us use a smaller current limiting resistor.
What do you want? One LED or three? Vote in the poll.

If you use a current source to drive the LED you can use small resistors. The most simple current source is a NPNBJT with a couple of diodes (in the base), a resistor in the emitter and the LED in the collector. If you need more info I can help but design equations are very simple.
wow! this is nice! :D
is it possible to use this thingy standalone us a universal remote like some very old casio watches?
Hi m3,
It could be, but it does not currently support that. It could be added to the firmware with some coding.
