Hello Two – hacking into the 2014 Hello Orb #ReverseEngineering
In 2014 a startup called Hello launched their first product on Kickstarter the “Sense”. This little orb of intricate injection moulded plastic was easily the most fully featured sleep tracking device available to consumers. The business model was solely based around sales with no ongoing service fees. This made the business very unsustainable. After attracting quite a lot of success and breaking into mainstream retail sales Hello folded in 2017.
Dev with Alex set about reverse engineering the Hello with the goal of reusing the the Sharp GP2Y10 dust sensor with an inexpensive modern microcontroller, the NodeMCU.
See how the sensor board was harvested, reverse engineered, and connected to the NodeMCU for use in the blog post here. To see the original being manufactured years ago, see this YouTube video.
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.
