Perovskite solar cells hit 21.1% efficiency and record reproduciblity

17.03.16 – EPFL scientists achieve the highest yet reproducibility for perovskite solar cells combined with a boundary-pushing 21.1% efficiency at normal operating conditions. Perovskite solar cells hold much promise for cost-effective solar energy. However, heat stability is an issue, and can significantly limit the solar cell’s long-term efficiency. A team of scientists led by Michael […]

Imagination lets MIPS take academic plunge

Imagination Technologies’ decision to reveal the inner-most secrets of the MIPS microprocessor architecture to academics could dramatically improve the teaching of electronics in universities. The MIPS architecture started off as an academic exercise by John Hennessy at Stanford University, and is the subject of a standard educational book by Hennessy and David Patterson. Imagination University

BooSTick – small AA voltage booster

Everything has now been ordered and paid for – the BooSTicks and the add-ons from Backerkit are all in process or on their way now. There were a few unexpected minor delays in the process of getting surveys set up and returned, accounts set up and linked and so on, so we don’t expect to

5V to 12V Step Up DC-DC Converter

Step up DC-DC converter is based on LM2577-ADJ IC, this project provides 12V output using 5V input, maximum output load 800mA. The LM2577 are monolithic integrated circuits that provide all of the power and control functions for step-up (boost), fly back, and forward converter switching regulators. The device is available in three different output voltage

Automatic monitor brightness controller

This is an automatic “monitor brightness controller” based on environmental light conditions. This system use USB port base sensor unit to measure the light level and control monitor brightness accordingly. We design this system to reduce the eye stress by matching the monitor brightness with environmental lighting. The sensor unit of this system is build

Wearable sensors analyze your sweat

Sodium. Potassium. Glucose. Lactate. Engineers at the University of California, Berkeley are focusing on measuring these components of sweat in an attempt to open an additional window into an individual’s health and well-being. A new device is able to calibrate the data based on skin temperature and transmit the information wirelessly in real time to

Building a Better RTL-SDR TCXO

Its hard to beat the cost and versatility of the ubiquitous RTL-SDR dongles, but the temperature stability of their reference oscillators isn’t sufficient for some applications. While the internal 28.8MHz quartz crystal in these units can be replaced by a high quality temperature compensated oscillator, these tend to be relatively expensive and/or difficult to source.

EnSilica adds DSP to RISC cores

EnSilica has added a 64-bit precision, fully-pipelined MAC unit to its RISC core to deliver the eSi-3260 for audio, sensor hub, motion control and touch screen applications. In addition to 32-bit data, the MAC unit supports dual 16-bit SIMD (single instruction multiple data) multiply and MAC operations. Uniquely, full complex multiplication is also supported, performing
