Marty McGuire of the Baltimore Node Hackerspace shared this neat coin-operated Chumby hack. Interfacing a Chumby to a coin slot is pretty cool all by itself, but the Super Mario coin sound takes it to the next level. Well done, Baltimore Node!
If you’ve been following me on Twitter or Google+ today, you’ll notice I’ve been pushing this thing called #hackfriday. It’s sort a counter-movement to Black Friday. Personally, I think the idea of camping out in a parking lot just to be granted the “privilege” of spending your own money is a little silly. While I have nothing against shopping or commerce, I find the compulsive herd mentality that develops around the Friday after Thanksgiving to be demoralizing. I much prefer to stay at home and make something or work on a project — I suspect many other people feel the same way. So, if you’ve spent the day working on something cool, I encourage you to post it up in the next few days on Twitter or Google+ with the tag #hackfriday.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
