SunDuino – Run your C application using solar power

Leave a Comment / Electronics News Updates /

SunDuino is a Single Board Computer with integrated Battery Charger, Voltage Regulators, I2C, Digital and Analog IO. It’s main benefit is that it can run a compiled C app for years on a small battery or forever using built in solar charger. A background RTOS provides SLEEP functions for reducing operating current to 100ua while providing 125ms periodic wakeups.

One step closer to the ‘ultimate battery’

Leave a Comment / Electronics News Updates /

With a theoretical energy density that is being compared to gasoline, Li-air batteries are expected to have 10× the energy density of a Li-ion battery. With the ability to be recharged more than 2,000×, this battery is 90% more efficient. The future goal? To use lithium-air batteries for electric vehicles. Some challenges still need to

LiTiny- A Tiny LiIon charger for most things battery

Leave a Comment / Electronics News Updates /

Lithium Batteries are indispensable. I have a few project like my own DIY Badge [Post Soon] or a Light Wand for Light Photography and an in-progress Mobile Rejuvenator which use lithium batteries ,usually those re-purposed ones that are sold in Local markets for Solar Lanterns with a capacity of 1100mAh. The lazy me used to

Buck-Boost Converters Help Extend Battery Life for Motion Detection

Leave a Comment / Electronics News Updates /

Contributed by Publitek European Editors 4/9/2013 Many security and motion detector systems rely on small, semi-autonomous nodes that are easy and simple to install. This implies the use of a battery-based power source and low-power operation in order to minimize the number of battery changes during the lifetime of the product. Over its lifetime, the
