Camping Light with 220V Recharger Circuit is a Rabbit Hole of Scary Questions
What seems like a nifty and novel device poses some big – and potentially shocking! – risks. With a full circuit diagram walkthrough from Big Clive:
This is a rather exciting camping and hiking light with some unusual features. Mainly the mains voltage referenced USB charging port and the equally mains referenced chrome ring round the flashlight button. This is definitely one for my electrical deathtrap collection.
If you have one of these then I would strongly recommend you either dispose of it or take extreme care when charging it from wall power as it does pose a high shock risk.
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.
