Safe >200mW burner UPDATED now with BR & red

Those of you who can remember my fist build ever (http://www.laserpointerforums.com/forums/YaBB.pl?num=1205258796/0) remember how I tried to make a nice child proof burner....

For those that forgot in order to use either laser you need to turn key switch which turns on an LED and a buzzer, flipping up the arm switch switches on red LED and deactivates buzzer. The pressing red button activates red laser and black activates BR- both CAN be used together!!

well I though to update the original with the following updates:

boosted red power to >100mW
rewired insides- dual on-board power supply allows 9V supply to last ages even at large currents
separate 6V on-board power supply allows the switches, leds and and reed relays to work
added 105mW module, boosted power to >115mW to bring it into new year!!

Pics to follow:

added second focusable module- this one is BR! >115mW

Can someone how me how to overexpose as this is so visible in real life:

Looks good.

I too use a key lock to stop my kids using my BR burner.
