While learning with my low budget hobby kit i would like to expand using a blue diode next to the green and red.
I am looking for a cost sensitive (want to buy full rgb later on but this is to get some hands on so cheap one for small rooms will be fine) blue laser diode to connect to my pt-itrust controller which supports modulation/blanking/ttl. Do i need a digro too??? i have one for red and for green so if i want to bundle the beams will a mirror for the blue be sufficcient and then send it throug red and green?
