Brooklyn, NY, March 25 — Patrick and I went to the Gowanus Canal to observe the testing of prototype water monitoring devices created at the weekend Water Hackathon. The Gowanus is one of Brooklyn’s more notorious Superfund sites.
We were excited to see that the device being developed by Leif Percifield and the citizen sensor group Don’t Flush Me is based on the water conductivity gadget we devised for Environmental Monitoring With Arduino.
We designed our gadget to test water samples in a controlled setting, such as sitting at your desk with the samples in flasks. They’ve adapted our water probe with little spade terminals, to be more durable in the field. Brilliant!
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.
