- I'd like to get some info CO2-lasers... I read the following on a BBS..
- If anyone has a sequel on this, please email it to me..

- LASER WEAPONRY / PART 1 / LASER SIGHTS
-
- by The Deceptor and Flip
-
- WELCOME!.....To part 1 of LASER WEAPONRY - to be included in each issue
- of ELEKTRIX. This first tutorial deals with building your own laser sights
- as seen in films such as 'THE TERMINATOR' and actually used by US military
- and UK M.O.D. for such weapons as ANTI-TANK GUNS, APRLs and other high-
- power military weapons. The type of sights mentioned here can be strapped
- onto the barrel/tube and provide perfect targetting - also phreaks people
- out if you walk down the street pointing the beam at people.
-
- NOTES:
-
- 1) The laser used is a helium-neon one which emits a bright red beam.
- 2) Pointing it in someone's eyes will probably blind them so be careful
- with where you point it - unless ofcourse you intend to do damage (?!)
- 3) It can't burn skin or paper or anything - it's only really useful in
- this case as laser sights - although in future issues I others will
- explain how you can use it for Data Snooping.
- 4) Total project cost is about 40 quid.
-
- WHAT YOU NEED:
-
- 1) A Helium-Neon laser tube.
- 2) A portable power supply (easily transformed into a backpack).
-
- A fairly decent tube can be obtained from BULL ELECTRICAL for about 25 quid
-
- J&N BULL ELECTRICAL
- 250 PORTLAND ROAD
- HOVE, BRIGHTON
- SUSSEX BN3 5QT
-
- The specs. of the JN BULL tube are as follows:
-
- Maker: Philips (holland) - could buy cheaper direct I guess.
- makers ref.no: LHN-VLP/04
- type: Helium-Neon
- Size: approx 260mm x 40mm
- Striking voltage: 6-8KV
- Running voltage: 1.2-1.5KV
- Output: 1.6mW (not bad at ALL! - usual MAX is around 2mW!!!)
- Running current: 5mA
- Polarity: white lead = negative
- black lead = positive
- Estimated life: 5000 hours
- Warm-up time: 1 second
- Wave length .63+0.01um (62.8nm roughly - red part of spectrum)
-
- Although the light emitted is actually red you'll only see the actual beam
- if the air is misty or dusty...though the spot at the end of the beam is
- perfect - the invisible beam is an advantage though if you don't want to
- be detected.
-
- I've included that info in case you pickup the beam as surplus stock some-
- where without the info. The tube isn't too fragile either - I dropped mine
- from two foot once - nothing.
-
- As you're going to need a power supply that's portable then you'll be hard
- pressed to find a company that does one....so here's the docs.

-
- I hope people understand those schematics - TXT files make life so hard!...
-
- If you can't understand something then contacts us at Palm Beach and we'll
- send u a photocopy of our own docs if you like (fax optional).
-
- Use:
- ~~~~
- Strap the tube (maybe put it in a protective casing too) to the barrel/tube
- and then FIRE AWAY!!!!
-
- If you point it at someones eyes or your own then you/they can say goodbye
- to them for good.
-
-
- Phun with your tube:
- ~~~~~~~~~~~~~~~~~~~~
- As well as being GR8 for sights you can use it for other things:
-
- ~ Shine it at a neighbours window while they're sleeping and the room will
- fill with a eerie red light!! haha - gr8....and this can be done from a
- few hundred feet with excellant results.....
-
- ~ Another good use is to point it just in front of someones feet while they
- are walking....The red dot on the ground will make them REAL paranoid!
-
- ~ Picking up conversations in buildings by bouncing the beam off a window
- and via modulation of the beam and conversion at the opposite end you can
- hear very high quality conversations without being seen or heard - this
- is a bit more tricky though....details in the next ELEKTRIX issue.
-
- ~ PLAIN TERROR! YERRRRR! PHUCK this is the bit I love.....walk down the road
- real casual or through a town centre....carrying your nice laser....aiming
- the beam at people as they go by....This really phreaks them out...best if
- you and a m8 piss about and make out he's gone blind. People will run fer
- their lives - you need to add a nice buzz noise to it - that really makes
- it seem quite an awesome device!
-
- That's it for this LASER WEAPONRY issue.....a great addition for any launcher
- ,tube, rifle, or just about any direct beam weapon......It could also be a
- fantastic sight for a carbon dioxide laser (needed since CO2 lasers are not
- at all visible - phun).....YUP! CO2 laser is in Part 2 of LASER WEAPONRY...
- fully portable and with over 200W output we are talking *** SERIOUS POWER ***
