 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

This is the latest pico-vga version with 47 Ohm resistor on Vsync and Hsync. I added two powerleds, one for USB-power and one for external power. The audio output is on the opposite side.  Greetings, Nick de pe1goo |

Nick, The PCB looks very good indeed and has all components except a few coils, connectors and the PCB. There is also interest in the pcb if you still have one or two left and can I take them over at cost price and shipping costs or do you live near The Hague or the Westland? In response to a question at my local computer club, I also worked with the same ws2812b module for the first time last week and achieved some results. They can all be controlled with different colors and brightness and if you want them off RGB(0,0,0). With this test example consumption is 3mA for an 8x ws2812b strip. Dim b%(7)=(RGB(0,0,10),RGB(0,10,0),RGB(0,10,10),RGB(10,0,0),RGB(10,0, 10),RGB(10,10,0),RGB(10,5,0),RGB(0,2,0)) SetPin GP21, Dout Bitbang WS2812 B, GP21, 8, b%() To come back to the question. This person wants a little more than a few leds. For a project he wants to control a strip of 5 meters with 500 ws2812b LEDs with Arduino software. I said possible with MMBasic but run into the limitation of 256 LEDs. And the ws2812b 100/meter are also hard to find but luckily found a seller on AliExpress. Jan |

250 WS2812s is still potentially 15A at 5V. That should be more than enough for anyone. :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |
