ARM-based desktop computer ? (Hybrid computers ?: Low + High performance ;)) No, AMD believes competition is good. AMD wants to secure discreete GPUs market by allowing nVIDIA to do its own APUs.

Cleaning Battery Contacts Hi, Some of the batteries in a lamp leaked and made a mess of the contacts. The contacts are springs that aren't very accessible so abrading off the residue isn't feasible. Is there a solvent or other means of removing the residue? Thanks, Gary ... 24 Jul 2010 02:41
Super Diodes and detectors Hi, This post was prompted by the recent discussion about Diode-Connected Transistors. The Crystal Set nutters are always seeking the holy grail of a perfect diode detector (it must be passive of course). The problem is that existing diodes are lousy rectifiers at low currents (three steps forward and t... 22 Jul 2010 04:52
Manufacturing of the decibel meter ? Hello, When was the decibel meter manufactured for the first time for mass consumption/law enforcement ? Especially in the Netherlands ? Bye, Skybuck. ... 24 Jul 2010 15:34
Larkinisms >>If you use wall-warts or they may saturate and not be as effective but by paralleling them you'll reduce the current and hence the total flux through each individual core. Paralleling the primaries does not reduce flux density. Reducing excitation voltage, or increasing frequency, does. A... 22 Jul 2010 20:14
Profibus VP power supply (+5V) Hi All, I'm designing a Profibus interface. I'm a little confused with the +5V termination power supply (Voltage Plus, or VP). My understanding is that VP is supplied by something on a segment that is used to actively terminate all the receivers, and usually these resistors are in the Profibus connectors the... 25 Jul 2010 16:12
Magic capacitors! Suppose you have two capacitors connected as --*-- | | C1 C2 | | ----- where * is a switch. What is the total energy before and after the switch is closed(in general). If you want to make it easier assume C2 is initially discharged. Is the energy before and after the same? If not explain why and... 11 Aug 2010 14:45
Low volume PCB fabrication in the Netherlands Hello, I need to find PCB manufacturer for my simple FR4 double-sided PCB prototypes. i dont find much offer on the Web. Anyone can help me ? Thanks a lot. Cheers, Rafael ... 29 Jul 2010 11:53
Driving capacitive loads with an H bridge Hi All, I need to drive capacitor with a triangle wave with no DC across the capacitor (i.e. a symmetrical bipolar drive but triangular) but it has to be efficient, i.e some kind of energy retrieval. Is it possible to use standard H bridge circuits to do this? Does anyone have any links or app notes? Tha... 26 Jul 2010 16:03
