Hi Electronics Gods,
I am a humble student trying to build a 556 timer laser circuit attached to a 9V battery where if I push the push-button, a blue laser light will turn on for 10s and after that it will turn off and another red laser will turn on for 10s and after that the whole circuit shuts off. The first laser requires 100 mA current and the second requires 170mA. I have 2 constant current sources build in the circuit using LM 317s. I have already made a schematic on LTSpice. I will be grateful if someone can simulate and confirm that it works. Attached is the .asc file. Thanks again! Want to run it for 60s for DC voltage.
