How many steps does it take to make an LED 'Party In A Bottle'? 1. Obtain bottle - by gift, by visiting Bombay Sapphire gin distillery, or by drinking contents. 2. Transport bottle home and into garden shed 3. Wait for a dry day and run extension lead from kitchen to shed. Connect drill to extension lead. 4. Check spoil hole is clear in 5mm diamond tipped drill bit & fit to drill in vertical bench press 5. Fill 5ml hypodermic syringe with water & fit blunt needle 6. Adjust bench press bed for round or square bottle 7. Adjust height of drill at rest to suit size of bottle (1cm clearance) 8. Set drill running at appropriate speed 9. Place bottle on drill bed and adjust position to match required cable entry point on back of bottle 10. Hold in place and drill dry for 10 seconds 11. Let drill up from bottle and apply 2 or 3 drops of water from syringe 12. Drill for another 10 seconds, or until water turns to slurry 13. Repeat from step 11 until extra noise or vibration occurs (near break-through) 14. Reduce downward pressure on drill to prevent glass breaking prematurely 15. Continue to drill lightly and lubricate until drill breaks through 16. Turn off drill 17. Remove bottle from drill bed and wipe exterior with kitchen paper towel to remove slurry 18. Take bottle into kitchen, rinse thoroughly to remove slurry & glass fragments (use sieve to catch glass shards) 19. Place bottle upside down to drain off & dry out in hot air cupboard for 24 hours 20. Select battery box (transparent, switched & enclosed, 2AA size) & solder in LED flasher IC with 2" output lead 21. Cut leads on battery box to required length, strip and tin ends with solder 22. Test outputs from battery box and mark negative leads (purple for flashing cct, black for static) 23. Secure battery box to bottle with transparent silicon mastic, leave to set for 12 hours or more 24. Select string of white LEDs and another string of coloured LEDs (or colours requested by end user) 25. Cut down LED strings to 5 LEDs each, trim leads to correct length, strip & tin ends with solder 26. Test LED strings and mark negative lead on each (purple for flashing cct, black for static) 27. Temporarily solder leads on each 5 LED string together (ready to hook to draw wire) 28. Insert draw wire into 5mm hole on bottle & feed through until it emerges from neck of bottle 29. Hook the 2 LED strings (where soldered together) onto draw wire 30. Pull draw wire and feed LEDs into bottle until ends emerge from 5mm hole 31. Remove draw wire and attach clothes peg to prevent wires slipping back 32. Unsolder temporary joints on LED strings 33. Secure 2 positive leads on LED strings together with short length of 3.2mm transparent heat-shrink sleeving (THSS) 34. Twist & solder those 2 positive leads together 35. Cut 15mm of 3.2mm THSS and fit over positive lead from battery box 35. Solder joined LED positive leads to positive lead from battery box (lap joint) 36. Locate THSS over soldered joint and shrink to fit snugly (with clean soldering iron) 37. Cut 2 pieces of 2.4mm THSS and fit over each of the 2 negative output leads from battery box 38. Solder purple LED lead to purple battery box lead (lap joint) 39. Locate THSS over soldered joint and shrink to fit snugly (with clean soldering iron) 40. Solder black LED lead to black battery box lead (lap joint) 41. Locate THSS over soldered joint and shrink to fit snugly (with clean soldering iron) 42. Gently pull LED strings at neck of bottle, and push sleeved joints back into bottle 43. With hot glue gun, seal wires into 5mm hole in bottle 44. With hot glue gun, seal wires inside battery box and tack flasher IC to prevent any movement 45. Test LEDs and determine mid point to suspend inside top of bottle 46. Attach 15cm length of thin line (or strong thread) securely to mid pointof both LED strings (tied together) 47. Feed all LEDs into neck of bottle, keeping hold of end of thin line/thread 48. With long prod, arrange LEDs evenly around interior of bottle 49. Secure thin line/thread with clothes peg in approximate final position 50. Mark off 25cm length on roll of iridescent florists cellophane (50 cm wide) - or 36cm if using 1 litre bottle 51. Cut approx 25 strips of cellophane (1cm wide or less) up to mark on roll - or 36 strips is using 1 litre bottle 52. Using special "stuffer" tool, distribute cellophane evenly around interior of bottle 53. Look at bottle from all sides, with LEDs turned on, and adjust for optimum effect 54. Adjust thin line/thread to final position and lock in place with original lid/cork 55. Before screwing/pushing lid/cork into final position, take 3 turns of line/thread around the neck of the bottle 56. Push or screw cork/lid fully home (aligned with neck collar label if there is one) trapping those 3 turns 57. Cut off excess thin line/thread and ensure end is tucked neatly out of sight 58. Take 1 metre of purple waxed cotton string and apply extra beeswax 59. Form a clove hitch around the appropriate part of the neck of the bottle. 60. Apply neat purple string collar using 'whipping' technique, with knot at back of bottle neck. 61. Trim final reef knot neatly and apply dab of adhesive. 62. Cut length of purple metallic tape long enough to go round neck of bottle & wide enough (say 5mm) to cover broken seal 63. Carefully apply adhesive around line of broken seal (UHU applied with tip of cocktail stick) 64. Carefully apply metallic tape onto glue with overlap at back of bottle neck 65. Leave to set for 1 hour 66. Check end of metallic tape is glued down, apply tiny amount of more glue if needed 67. Check bottle labels and neck seal to see if any parts unsecured - apply tiny amount of glue if required 68. Polish exteriot of bottle with dry cloth to remove finger marks and traces of beeswax by the neck whipping. 69. Check batteries and replace with alkaline AA cells if not fully charged. 70. Find somebody who likes what you did and is prepared to give it house room. 71. Invite lucky recipient to make a donation to fund purchase of more LEDs and toys for children's hospice. 72. Make a cup of tea. 73. Return to step no. 1 If you have the time, tools, materials & requisite skills to do all that, then you must be a retired Grumpy Old Git!
