I got a microscope at auction a few weeks ago for a great price, only issue is the lights are super dim.
I decided to make some supplementary lighting for it, this was my first little proof-of-concept, to show myself that all the formulas I learned back in physics really work and that I can put together simple stuff without destroying any components, and while understanding what I'm doing.
Next will be to rerun the numbers with 5V from a wall wart, then maybe start working on a housing for everything. It's been years since I tinkered with electronics and I forgot how much fun it is, I'm having a blast!
That's about all really, I'm super excited about baby's first breadboard and I'm just happy to be here!
Also, if anyone sees something that is a safety hazard, please let me know
Also also: Technically these aren't the correct resistors, they're allowing ~26 milliamps across the LEDs, when they're rated for 20, but I'm here for a good time not a long time
I remember for my intro to circuits final I did something similar to this but with a bunch of capacitors and called it the "explosion machine"
I love it
