Blockchain is also backing a new mode of mapping. Crypto-cartographers hope to use it for spatial verification—confirming that things are where they say they are, when they claim to be there. How might this be useful? Well, you could know precisely when an Amazon delivery drone drops a package on your doorstep, at which point the charge would post to your account. No more unscrupulous delivery drivers, and no more contested charges for packages lost in transit. Or when opening a new bank account, you could virtually confirm your permanent address by physically being there during a particular verification period, rather than providing copies of your utility bills. You could also submit a photo of your flooded basement or smashed windshield to your insurance company, supplementing your claim with time- and location-verified documentation. Or, as you pass by your local family-owned coffee shop, the owner could “airdrop” some Bitcoin coupons to your phone, and you could stop by to cash in before the offer expires a half hour later.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
