I have salvaged so many old lap-top batteries ( 18650 ) to reuse them in my solar projects.It is very difficult to identify the good cells in battery pack.Earlier in one of my Power Bank Instructable I have told, how to identify good cells by measuring their voltages, but this method is not at all […]

FOVEA is a wearable embedded analyzer — a multimeter targeted at embedded electronics with wrist-worn convenience. FOVEA, their wearable embedded analyzer does a few primary things to make embedded work easier: (a) It moves the multimeter display to a location that’s much closer to where the probes are being held, and also with almost the

Sound is produced by the PiezoListen piezoelectric speaker over a broader frequency range and with a greater output in the low range than any existing piezoelectric speakers, claims TDK. The speaker has an operating frequency range of 400 to 20,000Hz and achieves a high sound pressure of 80dB, even at low voltages of 24V peak to peak, or below. The PiezoListen

New modulation method increases operational lifetime of switching power units through digital, highly dynamic control and the use of film capacitors. Switching power units are used for the power supply of many electrical devices, e.g. computers, LED lights or laser welding equipment. They convert alternating current from the mains into the direct current required by
