Tidying my office a few days ago, I came across some car reversing monitors that I used to use as cheap Pi displays for use in the chase car, to show the distance and direction to the payload; these days I use the official Pi touchscreen as it’s a lot better for that application. One of the monitors is a flip-up model, and I wondered how much space there was inside. I use the Pi Zero a lot for balloon trackers, as it’s small and light compared to other Pi models, but perhaps one could fit one inside the base to make a smart dashcam – one that can stream my balloon chases to Youtube as well as record to SD.
About the same time, Michael Horne (author of the excellent Pi Pod blog), posted a picture of a similar-looking model on Twitter, asking how to power it from 5V. That’s the opposite of what I wanted to do (power the Pi Zero from the 5V rail inside the monitor) but I felt I might be able to help so I opened up my unit to find where the 5V could be tapped. As it turned out, Michael’s unit had a very different PCB to mine, but the seed was sewn so I decided to start building my dashcam.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
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.
