Hey guys dumb question from down under. There's been a couple of collisions lately, how can a navy ship collide with another vessel? I would have thought that there would be multiple radars being watched by automated control and warning systems as well as by people. Surely a dozen alarms are sounding several kilometers before a pending collision? Cheers.

Hi all, I am currently working on a range-switched photodiode design for use in our laboratory [1]. It took me a while, but I've arrived at a design I'm fairly happy with (in no small part thanks to Phil Hobbs' helpful writings on the topic): My current draft uses a simple BF862 source follower at the summing node of a ADA4817-based 2 M?/2 k? transimpedance amplifier to bootstrap t

Looks like NXP are phasing out the BF862: http://www.nxp.com/pages/n-channel-fet:BF86X?tab=Package_Quality_Tab Any alternatives in mind for simple low-noise transimpedance frontends and bootstraps? Having just started to design things using the BF862, I quite liked the fact that you can get reasonable noise performance without having to deal with (bootstrap/?) huge amounts of drain ca

Ugliest Apple iPad interior ever: Volt has a console that looks like something you'd want to drive, and not a smartphone. Guess GM engineers never told them that one of the biggest complaints about the 1st generation Volt was the no-tactile-feedback capacitive "buttons" on the control panel, customers complained so much that th

I have a 12 foot long frame that cantilevers in a pickup bed which is 8 foot with the tail gate down. The frame supports a weight that has a center of gravity about 9 foot from the supported end or about a foot past the end of the support. Of course the supported end is held down securely. I wish to make the frame transportable by splitting it in two so each piece fits in the bed. A ...
