Weather Station Needs Almost No Batteries

While the ESP8266 has made its way into virtually every situation where a low-cost WiFi solution is needed, it’s not known as being a low-power solution due to the amount of energy it takes to run WiFi. [Alex] took this design constraint as more of a challenge though, and with the help of an ATtiny microcontroller was able to develop a weather station using an ESP8266 that only needs new batteries every 2-4 years.

While the ESP8266 module consumes a bit of power, the ATtiny excels in low-power mode. To take advantage of this, [Alex] designed the weather station using …read more

False Claims On Kickstarter: What’s New?

Kickstarter and its ilk seem like the Wild West when it comes to claims of being “The world’s most (Insert feature here) device!” It does add something special when you can truly say you have the world record for a device though, and [MellBell Electronics] are currently running a Kickstarter claiming the worlds smallest Arduino compatible board called Pico.

We don’t want to knock them too much, they seem like a legit Kickstarter campaign who have at time of writing doubled their goal, but after watching their promo video, checking out their Kickstarter, and around a couple of minutes research, …read more

TORLO is a Beautiful 3D Printed Clock

What if you could build a clock that displays time in the usual analog format, but with the hands moving around the outside of the dial instead of rotating from a central point? This is the idea behind TORLO, a beautiful clock built from 3D printed parts.

The clock is the work of [ekaggrat singh kalsi], who wanted to build a clock using a self-oscillating motor. Initial experiments had some success, however [ekaggrat] encountered problems with the motors holding consistent time, and contacts wearing out. This is common in many electromechanical systems — mechanics who had to work with points …read more
