 Hello  All!
 
 LEDs!...  The  hype  is  so  much  nowadays  that  every  planted  aquarium  keeper  must  have  thought  atleast  once  to  take  the  plunge  and  try  them.  So  did  I   Very Happy  
 
 I  had  always  wanted  to  keep  a  small  planted  bowl  in  my  bedroom.  Since  the  light  requirements  for  a  bowl  would  be  minimal,  I  decided  to  try  out  LEDs.  My  main  planted  tank  is  still  running  on  PLLs  without  issues.  So  this  was  an  opportunity  to  learn  about  this  elusive  chip   Thumb Up  
 
 After  weeks  of  reading  and  loads  of  patience  I  was  finally  able  to  complete  this  project.
 
 The  parts  used:
 1.  CREE  XTE  5w  LEDs  x  2  Nos
 2.  Heat  sink  from  old  Processor
 3.  Salvaged  old  laptop  charger  -20V  DC  as  main  power  source  for  both  LEDs  and  Adruino
 4.  Arduino  Nano  -  for  PWM  dimming  and  timer
 5.  LM2596  DC  Buck  converter  for  reducing  20V  to  5V  for  powering  Arduino
 6.  Meanwell  LDD  1000H  -  LED  Driver  
 7.  TM1637  Seven  Segment  Display  -  for  showing  current  brightness  setting
 8.  DS3231  Clock  for  ON  /  OFF  timer  scheduling  of  lights
 9.  10K  Potentiometer  for  sending  brightness  input  to  Arduino
 10.  Single  core  wires  of  23  SWG
 11.  2.1mm  Male  &  Female  power  jacks  x  2
 12.  3mm  Acrylic  sheets  for  laser  cut  case
 
 The  display  comes  ON  only  while  setting  the  brightness  via  knob  and  stays  for  5  seconds.  The  controller  also  has  clock  feature  which  is  scheduled  to  switch  ON  lights  in  Morning  and  in  Evening.  However  if  I  need  to  switch  ON  lights  at  any  other  time,  I  have  included  an  over  ride  ON/OFF  button  :)
 
 The  raw  case  layout  was  made  online  at  http://www.makercase.com  .  The  downloaded  file  was  edited  in  corel  draw  for  adding  holes  for  display  and  buttons,  then  laser  cutting  was  done  at  local  acrylic  shop
 
 Pics
 
 
 
 
 
 
 
 
 
 
 
 Exploded  View  (DS3231  is  missing  from  its  place  on  top  left,  since  its  wired  up  for  another  project,  getting  a  spare  one  soon)
 
 
 Shabby  solder  work   Chuckle  
 
 
 
 
 
 
 
 
 
 
 
 
 Next  i'll  have  to  add  some  60  degree  lens  to  constrict  light  spread.  Also  LEDs  are  blinding  bright  at  full  capacity,  I  think  30%  to  50%  must  be  optimal  brightness  for  a  bowl..
 
 Thanks

 Where  did  you  get  the  5  watt  Cree  LEDs?  What  about  of  the  cost  of  each  LED?
