A few months ago I wrote about the Sonoff SC sensor hub by Itead Studio. It's a device with a Sharp GP2Y1010AU0F [Aliexpress] dust sensor, a DHT11 humidity and temperature sensor, an LDR as light sensor and a mic. The sensors are driven by an ATMega328P microcontroller but there is also an ESP8266 on board for WiFi communication, a pretty standard set up when you have several sensors and the ESP8266 GPIOs are just not enough....
Tindie is a great place to find uncommon electronic components or weird/interesting boards. I use to stroll around it's products to basically see what's new. It's like Kickstarted but for real. One such uncommon and new electronic components is the Panasonic's Grid_EYE AMG88 [datasheet, pdf] infrared sensor. And I first learn about it through Peasky Products breakout board at Tindie. And if you have been reading me lately you might know I'm going through my own LED fever....
There are so many ways to tell the time. DIYers have been doing clocks since the Ancient Egypt (obelisks lacked portability, thou). Every modern maker has a clock amongst her first projects. I have done some myself, including a fibonacci clock, a wordclock with a fancy green matrix effect and an unreleased project that hopefully will see the light someday soon. But recently I came back to the idea behind the wordclock before, to extend it in different ways:...
