I am designing a system that will allow me to take measurements of ultrasonic sound waves with an Onda hydrophone in an underwater environment. The ultrasonic transducer will be inside a water meter. The hydrophone will be mounted to a 3D gantry system allowing me to move it precisely around...
The circuit I wish to improve upon is located here:

I am trying to read data from an open collector output. That's why I have the pull up.
The transorb is clamping at 5.6V This is higher than the 4.1V max voltage on a pin. Also...
I've got a circuit I'm trying to design and have a few questions. I'm interfacing a microcontroller to a device with an open collector output. I'm trying to design transient voltage suppression circuitry. I'm looking into using transorbs but I couldn't find any that clamp at a voltage level...
I have a short video of a magnetic levitator I built and am trying to explain a curious effect.

Notice the washer oscillating side to side without touching anything? Can someone please explain what this can be attributed to?

Regarding specialization ... I don't forsee any work on FPGAs, DSP, ASIC, i.e. cutting edge tech where I work now. I'm not sure I want to work for the company for three to five more years and only be able to say I programmed MSP430 micros.
On another note (loosely connected),
The company I...
I have been lurking in the forums for some time now, and I am really impressed by the breadth and depth of the engineering knowledge the posts reflect. I graduated in 2003 with EE and 2005 with MSEE. I have been professionally employed as a electrical design engineer for nearly two years at...
