VoIP Telephone Teardown – with Serpentine Traces & Other Features
Inside every plastic-chassis device there’s a wealth of exploration and sometimes head-scratching awe awaiting you. Now what’s really crazy about this VoIP telephone is that it’s only from 2011…yet seems so ancient. I mean the iPhone 4 was already out by then, which really dates this tech. Nevertheless you get what you pay for and I always open up old electronics to not only inspect them but possibly to harvest them! I save pushbuttons and toroid core inductors – and a phone like this contain both! And then you sometimes stumble upon unique design choices like the serpentine traces surrounding the Samsung SDRAM in the image below – possibly to make the length of all the traces uniform or within a specified range? Weird! Always fun finding things like that in teardowns!
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.
