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

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	...
Find	  the	  bu@on	  you	  were	  able	  to	  read	  with	  the	  IR	  receiver.	  Follow	  the	  path	  of	  that	  bu@on...
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	...

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.

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.	  solde...
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.

Transcript of "Ir guns building instructions"

  1. 1. IR  guns  Building  instruc/ons  
  2. 2. To  make  an  IR  gun  we  need  a  remote  control  and  a  toy  gun  
  3. 3. On  the  other  hand  we  need  a  IR  receiver  and  a  Arduino  breadboard  
  4. 4. 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).  
  5. 5. Remove  the  ba@eries  of  the  remote  control  and  open  it.  
  6. 6. Now  we  can  see  the  breadboard.  On  one  side  we  can  see  al  the  bu@ons.  
  7. 7. On  the  other  side  we  see  some  electronic  components.  The  most  important  one  is  the  IR  LED  which  sends  the  signal.    
  8. 8. 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.  
  9. 9. Cut  the  housing  of  the  remote  control  trough  par/ally  just  under  the  bu@ons.  
  10. 10. Now  we  can  break  the  housing  in  2  pieces.  
  11. 11. Put  the  breadboard  back  in  the  housing.  
  12. 12. Put  the  ba@eries  back  in  the  remote  control  
  13. 13. Turn  the  remote  control  around  
  14. 14. Connect  the  2  points  you  found  with  a  wire  and  look  if  you  receive  the  signal  with  your  IR  receiver.  
  15. 15. If  you  receive  the  signal,  solder  a  wire  to  each  point.  You  can  be@er  do  this  with  a  precision  solder  tool.  
  16. 16. Make  sure  the  cable  is  long  enough  and  tape  it  to  the  remote  control  so  the  point  doesn’t  get  loose.  
  17. 17. Repeat  this  for  the  second  point.  
  18. 18. Desolder  the  IR  LED.  Mind  the  polarity!  Write  it  down  or  mark  one  of  the  legs  of  the  IR  LED  so  you  know  it.  
  19. 19. Solder  2  wires  to  the  connec/on  points  of  the  IR  LED  on  the  breadboard.  
  20. 20. Here  you  can  see  the  2  wires  soldered  to  the  connec/on  points.  
  21. 21. Now  take  the  toy  gun  and  unscrew  al  screws.    
  22. 22. Open  the  gun  and  take  the  part  with  the  electronic  components  in  it.  
  23. 23. Make  a  small  cut  in  the  material  so  we  have  a  gap  to  place  the  wires  in.  
  24. 24. Here  we  can  see  the  2  gaps  for  the  wires  
  25. 25. Loosen  the  motor  that  is  posi/oned  in  the  barrel  of  the  gun.  
  26. 26. Make  a  gap  on  the  side  of  the  barrel  to  place  the  wires  of  the  IR  LED.    
  27. 27. Look  where  you  are  going  to  place  the  breadboard  of  the  remote  control.  
  28. 28. 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.  
  29. 29. Place  the  cable  for  the  IR  LED  in  the  gap.  Mind  that  the  motor  can  spin  without  touching  the  wires  
  30. 30. Place  the  cable  of  the  IR  LED  in  the  gap  between  the  barrel  and  the  body  of  the  gun.  
  31. 31. Cut  the  cables  to  the  appropriate  length.  
  32. 32. Glue  2  small  switches  together.  
  33. 33. Take  the  trigger  out.  
  34. 34. Mark  the  points  where  we  need  to  drill  a  hole  for  moun/ng  the  switches.  
  35. 35. Take  drill  of  1mm  diameter.  
  36. 36. Drill  the  2  holes  you  marked  earlier.  
  37. 37. Put  a  small  amount  of  glue  on  the  back  side  of  the  switches  and  put  them  in  place.    
  38. 38. Solder  the  2  wires  from  the  remote  (bu@on)  to  the  first  switch.  
  39. 39. Cut  the  wire  that  comes  from  the  +  pole  and  go’s  to  the  breadboard  inside  the  gun.  solder  the  cables  to  the  other  switch.  
  40. 40. Solder  the  switch  that  was  already  in  the  gun.  
  41. 41. Fire  the  gun  and  see  if  everything  works  
  42. 42. Measure  on  which    2  connec/ons  we  have  3V  because  the  remote  control  needs  3V.  
  43. 43. Connect  these  2  points  with  correct  poles  of  the  remote  control.  
  44. 44. Solder  the  IR  LED  to  the  cables.  
  45. 45. Place  the  second  half  of  the  gun  on  top  of  the  other  half.  
  46. 46. Put  all  screws  in  place  and    /ghten  the  screws.  
  47. 47. Repeat  this  for  the  second  weapon  
  48. 48. Mark  1  of  the  guns  so  you  know  which  weapon  has  which  code.
