This is basically a Self-Driving Car powered by Arduino R-3 Development Board and a L293D Motor Shield.It uses the data given by the HC-SR04 Ultrasonic Sensor which is connected to analog pins of the arduino board. As an additional feature, I have added a Micro 90g servo which the ultrasonic sensor is fixed to. Basically […]

Consumer electronics aimed at young children tend to be quite janky and cheap-looking, and they often have to be to survive the extreme stress-testing normal use in this situation. You could buy a higher quality item intended for normal use, but this carries the risk of burning a hole in the pockets of the parents.

Meet Temper, a compact, low power temperature sensor based on ESP8266 and SHT30 with a large 13×7 pixel led display. It accesses WiFi periodically to display temperature and humidity data as well as battery percentage via the MQTT protocol. The device’s display uses three 74HC595 + 7 n-fets, TP4054 to handle battery charging through a USB and MCP1700T LDO to power the ESP. For WiFi setup, Temper

A number of smartphone manufacturers have, for a while, been experimenting with E-paper displays with phones like the Hisense A2 and Yota’s Yotaphone 1 and 2 implementing an e-paper based display as a secondary screen. While the use of e-paper displays brought advantages like extended battery life, and reduced pressure on the eyes in bright lights, for phones like

It’s becoming quite obvious that traditional batteries are limiting the progress of IoT devices. They are expensive, they contain harmful chemicals and most importantly All-Batteries-Will-Die. Vemund Kval Bakken chief technology officer and co-founder at ONiO say the real problem with the battery approach to IoT comes when you actually consider the battery shelf life as well as the environmental
