Hi there, I need some help in making a very basic unit, which consists of 3 x AA battery holder 4.5v, Toggle switch, L.E.D light, 1 meter cable with opposing crocodile clips + & - (red and Black) this needs to be set in an White ABS Plastic waterproof box. I need 50 units built once the design and sample box has been inspected. any upgrades are welcome like use of different on/off switch f...

I have an opamp with a 10 volt positive supply and need the output to swing to about 16 volts. I was thinking I could add a paralleled 6.8 volt zener, a cap, and a floating power supply at the opamp output. The power supply could be a PV optocoupler like this: https://www.digikey.com/en/products/detail/toshiba-semiconductor-and-storage/TLP3905-TPR-E/78098 04 My load is obviously light, a

This is a DAC-programmed power supply, 48v in and 0-36 out maybe. I want to use the TI switcher, but I don't know how to wedge it into LT Spice. One of my guys can run the TI simulator, so I'll let him tune it with the TI part. We might do programmable current limiting in an FPGA, based on the current shunt measurement.

Dear forum members, My promised book on semiconductor devices has been published by Springer and is available at: https://link.springer.com/book/10.1007/978-3-031-45750-0 If purchased from the Springer site, the book is available chapter wise - one can buy chapters of one's choice. The traditional paper copies(hard|soft cover) would I think be available in a few weeks from

Two styles of electrostatic treatment vessels, one is a circuitous snake route. Each trough has 11" square plates 1" apart. Easy to calculate plate area vs volume. Now, also looking at a coaxial pipe within a pipe. 4" inner pipe with an 8" outer pipe. I can't get my head around the treatment area vs volume on coaxial pipes. The electrostatic voltage will have to higher because of mor

In the May 22 to June 4, 2023) issue of Aviation Week, on page 5, there was a very interesting long letter from Greg A Lloyd of Pullman, Washington, to the editor on the practicalities of the Hydrogen Economy, in particular as it applies to aircraft propulsion. Basically, it's not even close to practical, and he lays it out point by point. The URL is
