Anybody Be Interested In One Of These?

[gumflapper]

a few weeks ago a mate of mine at work told me his parents house got broken into and asked if i could make something (like an alarm) to let you know when someone had entered the property. i said yeh i might be able to and i did some research on the internet and came across this...

Protect your home with lasers -

i did some prototyping and testing and a few weeks later i eventually built this...

this board is slightly different then the 1 produced by kipkay as i desgined it for a 12VDC power supply to operate. it also uses a different transistor to operate a 12V relay (or 12V siren depending on whats required) and has a circuit to power the laser and a few leds to let the user know what is going on. the basic idea is shown in this crappy diagram i just drew

power can be provided by a car battery or a 240VAC/12VDC adapter.

now that i have a working prototype i was wondering if there would be any interest in having these professionally made. thru work i am able to get proper PCB's made (all with proper solder masking/silk screening etc.) only thing is to do it "cost effectively" i'll need more then a 2 people at work who want 1. there seems to be quite a few people on the net (various sites like instructables) who have had trouble making something like this and i would offer these boards as either a DIY kit (people buy the board and parts and assemble the kit themselves) or as 1 complete assembled tested unit. pricing would depend on the quantity of people who would want 1 of these and the more people that wanted them, the less it would cost. eventually if this ever took off sell them on ebay...

so i am asking, is there any interest here for these? would anybody be interested in purchasing 1 when/if i get them built?

thanks

don't mean to be negative or putting you down but a standard household alarm would work better. just setup specific zones, the companies who build these alarm would have thought of this idea and implemented it, if it was more successful then a convectional alarm.

unless you can make these lasers powerfull enough to cut through flesh and bone

in which case, put me down for 7

well i could get hold of a few that would singe ur pubes provided you walked past them in the nude...

but yeh, this idea is not to replace a conventional alarm as such, mearly as a cheaper option for people who do not want to spend hundreds/thousands of dollars on professional alarms... this obviously can be used infront of walkways/doors at night time (or day). just turn it on and go to bed and in the morning turn it off again.

anymore thoughts/suggestions would be appreciated

thanks
