    Ir guns building instructions Ir guns building instructions Presentation Transcript

    • IR  guns  Building  instruc/ons  
    • To  make  an  IR  gun  we  need  a  remote  control  and  a  toy  gun  
    • On  the  other  hand  we  need  a  IR  receiver  and  a  Arduino  breadboard  
    • A=er  installing  the  IR  library  for  arduino  and  making  the  IR  receiver  work  we  push  a  bu@on  on  the  remote  control  and  look  which  bu@on  we  can  receive.  And  we  write  down  the  code  we  receive  (A81  in  our  case).  
    • Remove  the  ba@eries  of  the  remote  control  and  open  it.  
    • Now  we  can  see  the  breadboard.  On  one  side  we  can  see  al  the  bu@ons.  
    • On  the  other  side  we  see  some  electronic  components.  The  most  important  one  is  the  IR  LED  which  sends  the  signal.    
    • Find  the  bu@on  you  were  able  to  read  with  the  IR  receiver.  Follow  the  path  of  that  bu@on  and  find  2  points  that  are  easy  to  solder.  
    • Cut  the  housing  of  the  remote  control  trough  par/ally  just  under  the  bu@ons.  
    • Now  we  can  break  the  housing  in  2  pieces.  
    • Put  the  breadboard  back  in  the  housing.  
    • Put  the  ba@eries  back  in  the  remote  control  
    • Turn  the  remote  control  around  
    • Connect  the  2  points  you  found  with  a  wire  and  look  if  you  receive  the  signal  with  your  IR  receiver.  
    • If  you  receive  the  signal,  solder  a  wire  to  each  point.  You  can  be@er  do  this  with  a  precision  solder  tool.  
    • Make  sure  the  cable  is  long  enough  and  tape  it  to  the  remote  control  so  the  point  doesn’t  get  loose.  
    • Repeat  this  for  the  second  point.  
    • Desolder  the  IR  LED.  Mind  the  polarity!  Write  it  down  or  mark  one  of  the  legs  of  the  IR  LED  so  you  know  it.  
    • Solder  2  wires  to  the  connec/on  points  of  the  IR  LED  on  the  breadboard.  
    • Here  you  can  see  the  2  wires  soldered  to  the  connec/on  points.  
    • Now  take  the  toy  gun  and  unscrew  al  screws.    
    • Open  the  gun  and  take  the  part  with  the  electronic  components  in  it.  
    • Make  a  small  cut  in  the  material  so  we  have  a  gap  to  place  the  wires  in.  
    • Here  we  can  see  the  2  gaps  for  the  wires  
    • Loosen  the  motor  that  is  posi/oned  in  the  barrel  of  the  gun.  
    • Make  a  gap  on  the  side  of  the  barrel  to  place  the  wires  of  the  IR  LED.    
    • Look  where  you  are  going  to  place  the  breadboard  of  the  remote  control.  
    • Remove  enough  material  so  it  is  possible  to  place  the  breadboard  of  the  remote  control  inside  the  gun.  And  mount  the  breadboard  inside  the  gun.  
    • Place  the  cable  for  the  IR  LED  in  the  gap.  Mind  that  the  motor  can  spin  without  touching  the  wires  
    • Place  the  cable  of  the  IR  LED  in  the  gap  between  the  barrel  and  the  body  of  the  gun.  
    • Cut  the  cables  to  the  appropriate  length.  
    • Glue  2  small  switches  together.  
    • Take  the  trigger  out.  
    • Mark  the  points  where  we  need  to  drill  a  hole  for  moun/ng  the  switches.  
    • Take  drill  of  1mm  diameter.  
    • Drill  the  2  holes  you  marked  earlier.  
    • Put  a  small  amount  of  glue  on  the  back  side  of  the  switches  and  put  them  in  place.    
    • Solder  the  2  wires  from  the  remote  (bu@on)  to  the  first  switch.  
    • Cut  the  wire  that  comes  from  the  +  pole  and  go’s  to  the  breadboard  inside  the  gun.  solder  the  cables  to  the  other  switch.  
    • Solder  the  switch  that  was  already  in  the  gun.  
    • Fire  the  gun  and  see  if  everything  works  
    • Measure  on  which    2  connec/ons  we  have  3V  because  the  remote  control  needs  3V.  
    • Connect  these  2  points  with  correct  poles  of  the  remote  control.  
    • Solder  the  IR  LED  to  the  cables.  
    • Place  the  second  half  of  the  gun  on  top  of  the  other  half.  
    • Put  all  screws  in  place  and    /ghten  the  screws.  
    • Repeat  this  for  the  second  weapon  
    • Mark  1  of  the  guns  so  you  know  which  weapon  has  which  code.
