So I am designing another driver for high power blue LD. PCB etching is always a nightmare to me. I ended up picking up my hand drill and engrave the board myself. To be honest. It save me up to 500% time to make the board this way. Oh yeah it doesn't look good but who care? The last picture does loo like a sim card to me :D. Will solder the components will I have spare time. Thanks for watching.
