Toy guns are an excellent medium to practice your cyberpunking skills. Already in generally the right shape, cheap, and often equipped with lights and sounds, toy guns offer many bonuses a scratch built gun doesn't. Amongst them is ease (customize and slap some paint on), and effects (lights are easy, but sounds aren't). In this Instructable I'll document the transformation of my gun from a child's toy to a rebel's best friend in the future struggle for freedom. Also handy for time travelers, bounty hunters, vampire slayers, costume and prop makers, or anyone needing something with a little more... kick
Step 1: Selecting a Gun, Materials
Righto, the best toy guns for improvement are ones worth improving. Lights, sounds, screws, minimum/no glue or heat welds, good shape, fairly sturdy, are all signs that the toy needs to be reborn as a tool. Avoid ones that are difficult or impossible to disassemble. Cheap squirt guns are another option, they cant be taken apart, but many greatly resemble real guns, and make good cheap props.
As far as customizing goes, a big bin of random bits of junk is great. I used:
a dish soap bottle nozzle
a piece of what I think was a extension cord roll holder
an odd electrical fitting left by the telephone man and discovered when I ran it over with a lawn mower
lots of bits from a cd player
for the heads-up display, I used some copper wire, a antennae coil, a coil from a mechanical pencil, laser diode and scan lens from a broken cd player (non functional), the lid from a flash drive i took apart, and of course a pair of shooting glasses
As far as paint, spray paint is king. It may be wise to apply a spray on plastic primer, as some plastics just don't like spray paint. For superfine detail work, model paint. I went for a gray/blue/black color scheme.
For gluing together, I used E-6000. It's cheap, gloopy and it holds. Epoxy and JB Weld also work.
If your mucking about with the electronic effects, a soldering iron, solder, wire, and whatever else you need will be needed.
You'll also need a screwdriver of the appropriate type, hacksaw, and a razor blade / exacto knife
