After witnessing the image of a mosquito in a laser beam outside, I decided to investigate the phenomenon further. I started by locating scuzzy water. Ponds lacking, I decided to take water out of the bowl of my 6 year old spider plant. I then filled a syringe and hung it above a laser so that a drop of water, almost ready to fall, was in the beam path. Below is the incredibly complex apparatus involving a book, sticky-tac, a random bottle, a 250mW laser, and a syringe. Here is the thread discussing this on LPF if you’re interested.
The cat seems to like the bug-filled water 🙂
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
