RGB led lighting module

Hello

I’ve started a new project: a RGB led lighting module, that can be controlled from a central communication node.

I’ll be using some SMD rgb leds, in 5050 case, that i  got from e-bay.

The Imax is specified to 40mA, but i’ll be running them at 30mA max, to keep the heat down.

The design features are :

  • 50x50mm per module
  • cheap controller, JTAG interface, enough cpu power for high resolution/ speed PWM
  • the ability to run stand-alone, following a pre-programmed sequence
  • RS485 line drivers
  • wide input voltage range

Ceas cu afisaj VFD

Ca o prima postare am ales un proiect mai “aratos”: un ceas cu afisaj VFD

Pentru afisaj am folosit un tub IV-18:

IV-18 tube

IV-18 tube

Caracteristicile tubului sunt:

  • 9 digiti, 8 cu 7 segmente si virgula, 1 cu simboluri speciale.
  • tensiune de filament : 5V la 85mA
  • tensiune anodica: 20-30V
  • curent de grila: 11mA per digit
  • curent anodic: 8mA per digit, cu toti anozii aprinsi
