Li-Ion battery manufacturers provide protection circuits, which are often built into their batteries.
These are based on special purpose integrated circuits which control one or two MOSFETs to isolate the battery if the terminal voltage is over or under certain specified voltages. The circuit...
This relates to my 50KHz ultrasonics problem, but presumeably relates to all acoustics.
1. A transducer can convert electrical energy to acoustic energy.
2. Another transducer converts acoustic energy to electrical energy.
I can build a driver with a flat frequency response for the first...
This is hardly a technical question, but someone in your group might know the answer.
I am located in the UK.
I need to pipe light over multiple paths which vary from 1 to 5 metres.
The exit aperture for the light needs to be about 2mm.
The budget is a bit limited.
Where can I source a reel of...
I have on my bench a stainless steel plate with a piezo ceramic transducer (50mm diam 5mm thick) bonded to it.
I need to build an efficient driver to pump power at 50KHz into the device. The end product will deliver ultrasonic energy into a glass container to excite particles suspended in a...
