This is my DIY Fish cam and sonar, which is comparable to the functionality you would find in some of the more expensive units like the Marcum LX9, which cost upwards of $1300 or more, whereas I was able to built this for about 1/3rd that cost at around $300
It works absolutely amazing, and my uncle who has the Marcum LX9 was actually quite impressed at the picture quality of this camera, as well as the fact that it has 150 feet of cable, versus the 75 feet of cable that he was limited to which effectively makes the camera in those more expensive units useless for deeper water fishing.
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.
