My Chrysler 300M has lights that won't turn off. I like to look at the stars at night with the radio playing and with my door open, but the lights don't go out. I have designed an electric switch controller that I want to insert into the battery cable. Has another electronics designer provided a legal alternative? In my design, the microprocessor power bus is intercepted at 17 point

..almost every place and their pet goldfish wants to shove their "DriverUpdater" malware down your throat; as a side issue they all ASSume Win7 and/or Win10. There was one place (presumably IBM) that had specific drivers for Win3.1 up to Win7 (the IBM 5152 which is supposed to be compatible) each OS nicely listed, but ALL of the links were bad. The Epsom LX-1050 is also supposed ...

Not sure how I missed this one for two months. I see there is already some serious contention with Atmel employees. http://www.eetimes.com/document.asp?doc_id=1329412 I wonder what it will be like for the sales force to be selling PICs, AVRs and ARMs all into much of the same market space? I wonder if the PIC32 will finally bite the dust with ARMs all around it crowding it out of t...

I'm designing a benchtop gadget that will uses a 7020 ZINQ SOC chip, which is an FPGA with two ARM cores on-chip. I want to save a user's last setup when power fails, and restore it at powerup. The 7020 has on-chip batter-backed ram, but apparently only to store some encryption key, not for general use. So I need an external ram and a battery. Digikey offers exactly 4000 choices when I...

Hi, all:- Just prototyping a board with some SMT 0603 LEDs (L296 series) and I noticed the OSRAM LEDs were supplied on the usual 8mm tape, but with double density (two LEDs for every linear sprocket hole). Is this going to cause problems with older SMT equipment? http://pages.interlog.com/~speff/ledtape.png --sp -- Best regards, Spehro Pefhany Amazon link for AoE 3rd E...

Hi all The LT1302 is used for the minti boost, because it can deliver 600mA, while other LT1301 can deliver only 200mA but also at 3.3V. LT1306 seems like a good choice for me, except that I cannot buy it here. MAX757 has the power options, but still only at 600mA Is there a version that can provice 500+ mA and at 5V and 3.3V wbr Sonnich

I have a small collection of the tall halogen pole lamps with the dish shaped reflector which lights the ceiling. I'm actually fond of them and like the indirect light they provide. I don't like burning 500 watts of power though. So I thought I would try replacing it with LEDs. A direct replacement for the halogen bulb gives of a fraction of the light, so I found some modules which a...
