Greetings friends,
I have a cool problem I'd like your help with (pun intended) - I have a fan that I want to be able to accurately point and I would like to add a laser module to it to do so. I want to be able to push a button to activate the pointing laser such that after about 20-30 seconds it goes off on its own. The module is a standard 3-5V 650nm variety. I do not want to use a relay for space reasons. I plan to use an old USB plug's innards to generate the power for the circuit and wire it in the fan housing using a 3D printed mount to keep the laser module in place. Is this a life-changing application of electronics? No. Will it give me a fun project through which I can learn more about circuits? I sure hope so.
Thanks for your help.
P.S. I do have quite an assortment of transistors, MOSFETs, resistors, capacitors, inductors, etc. to work with.
