A word of warning! Lasers are not toys and need to be used with care, lasers should always be used with safety goggles designed for the wavelength being used. Always be aware of others around you when using a laser, eyes are not replaceable!
The laser diode used here was the best available when 007 was a boy, much more powerful ones are available now so do your own research to find what you need..... This setup will light stuff easily enough but is weak by modern standards.
Step 1: General arrangement
This build, though not complex is very fiddly to do as there is not much room to fit everything in, but if you want to have a go here is the information you will need.
This is the General arrangement that I worked from.
List of parts:
Flip-top lighter of your choice (I used a Star lighter from ebay).
Blu-ray laser diode (PHR 803T)
Aixiz module (front end and lens only, Outside diameter turned down to 10mm).
Small block of aluminium (heatsink/optics holder).
Driver (I used the low range Rkcstr driver, google is your friend).
Push button (I took one from a broken DX green laser)
Batteries (GP 10A [9v 38ma/hr]).
Small pieces of scrap brass sheet, for contacts and springs.
Small piece of plastic for mounting driver and insulating battery contacts.
Various colour insulated single strand copper wire.
