Where do they connect auto immobilizer? Ignition wire is simply, but too simple and obviously easy to by-pass. For my old Ford, i disable it with the crankshaft sensor, since it would not start without it. I am using Intel Edison or Raspberry Pi to control an relay. Both can do the job. Edison is better because of the small size and embedded flash; However, it is also worse

Is an STM32F437VGT7 an exact plug-compatible superset of STM32F417VGT6?

Sorry to ask this rather obscure Q but ST "engineering" is not really contactable via any normal means... It looks like a superset in every way, comparing the data sheets. They even made the 2MB of flash in the 437 as two 1MB banks, which rather defeats the point of having 2MB unless you can generate "large model" code like one used to do with the old Z80 etc if wanting to have > 64k of

A friend of mine is trying to learn about simple CPU architecture, and was asking for recommendations for microcontroller development kits. I've done a lot of design on that level, but it's been years. I assume there are some cool new toys now. Here's what I thought was appropriate: Inexpensive microcontroller/microprocessor board with flash ram and some ports with LED's etc. Maybe AD/DA...

I want to concoct a trigger to fire my camera when there's lightning in the area of where the camera is pointed. I do not want one of the RF burst detectors, as I don't care about lightning that's not in front of the camera itself. I'm thinking about some sort of photodiode mounted in a housing peeping through the viewfinder for actual flash detection. Past that, I'm not too sure of wha...

I'm not formally trained in this stuff, so I have some serious knowledge gaps that get me in trouble sometimes. This situation involves using a USB- to-serial adapter to flash firmware to a microprocessor in-circuit, and whether the adapter can, or should, provide 3.3V power to the MPU during this process. So if the adapter provides power, and the regular power is switched off, it wou...

This is an idea for an experiment I may or may not do. The background: There have been reported seasonal variations in radioactive decay in the past.

I have a need to take a square pulse of 0V/+5V and about 5-10ms duration, and stretch it out long enough to flash a LED brightly enough to be visible indoors under "ordinary" lighting conditions. I currently only have op-amps on the board and would rather not add any logic ICs to do this. So using low-speed op amps and discretes would be fine. The pulse source into the stretcher would...

I used to know DOS pretty well. I am copying a lot of files to a flash drive for backup and need to verify what has been transferred by comparing directories. A simple count is sufficient. Trouble is I'm getting incomplete data. I'm using a DIR command to a file, then examining the files to see how many files are missing. My text editor can do a diff if the counts don't match.
