I am currently working on the initial preparations for a somewhat larger project. For this I need LEDs that shine a little brighter.<\/p>\n\n\n\n

At the same time, I didn't want to do without the convenience of the familiar WS2812 aka Neopixel LEDs. <\/p>\n\n\n\n

For those who have not yet heard of them: These have the great advantage that they can be connected to each other like a kind of shift register. This means that only one GPIO of the microcontroller used is required to control up to 512 LEDs. Nevertheless, the brightness\/color of each individual LED can be set individually.<\/p>\n\n\n\n

Unfortunately, the WS2812 LEDs are currently only available as a 5050 SMD version. They can be supplied with a maximum of 20mA per color. The brightness is not bad. But for lighting in direct daylight, it could be a little tight.<\/p>\n\n\n\n

That's why I designed the nanoPxl mentioned here. I got the original idea from kd_technology <\/a><\/em><\/strong>and then modified it a little. <\/p>\n\n\n\n

The 5730 LEDs used have a forward current of 180mA. They are therefore correspondingly brighter \ud83d\ude42 <\/p>\n\n\n\n

Here are a few impressions of the assembled nanoPxl and the instructions for rebuilding it. <\/p>\n\n\n\n
