This is strange. Looking at the page now, they seem to have slipped another decimal place!  Now 0.47c each for 10, down to 0.3c each for 5000.

Shirley shome mishtake?

Seems to be fixed now

Yup. I should have bought some :-)

Maybe you need a very specific kind of LED driver (not available COTS), to drive a few $0.01 LEDs each, let's say an RGB LED. Then you need a matrix of 1000 such LEDs.
Why not use a LED with built in communication like they do in the LED tapes?
Example: WorldSemi WS2812B
You should never go down on equipment!

Maybe you need a specific LED for reasons like wavelength or emission pattern, and addressable LEDs don't have suitable properties.

Are there any good free/cheap 8051 compilers ?
Are there any good paid for 8051 compilers, after Microchip bought up and closed down Hitech?
I though Keil were always the go-to people for 8051, or were they just the first?


IAR was first, EW8051 ramped up when Keil was bought by ARM.  Those cheap and novel 8051 based micros need compiler support and some manufactures were not willing to talk to an ARM related company.. Silabs, Winbond, megawin, teridian, ASIX, some niche RF chips etc

Did anyone manage to build an asm project with the Padauk tools?
