My son's car (2016 Peugeot 208) quite suddenly threw up some alarming-looking warnings recently about ABS, ESP and tyre-pressure monitoring not working.

This turned out to be more annoying problem than I expected.

This wasted several hours on me.

Consider this bit of code:- def foo(): print("Called foo()") try: print("In the 'try' block") 10 / 0 except Exception as e: print("Got an exception: ", str(e)) finally: print("In the 'finally' block") print("About to return from foo() at the bottom") foo()

This is a follow-up to my earlier earlier post: if you haven't already done so, I suggest reading that one first.

If you are using the millis() function to measure time on an Arduino, you might be tempted to do something like this:- unsigned long timer_expires_at = millis() + SOME_DURATION; while (millis() < timer_expires_at) { [do other stuff while waiting for the t…

Let me state from the outset that my knowledge of RF and antenna design is very rudimentary.

These are wonderful little things.

This was a pain-in-the-ass to troubleshoot, so I'm sharing the story here in the hope that it will help someone else.

A weird Windows 10 problem this morning.

The 30/40dB pad from my previous post works fantastically well.

I had a requirement to connect the (line-level) output from a small mixing desk into the microphone input on my camera (mic-level, obviously).

Modern smartphones have a wealth of sensors that provide all sorts of avenues for amusement for modern geeks.

Something I have always found a little confusing was the idea of signal mixing.

I have been studying the classic and venerable 555 Timer IC recently and have created an animation showing the various signals on it as it moves from state to state. http://bogpeople.com/555/ Also a video...

I ran into an interesting problem in work today.

Like lots of electronics hobbyists, I have an old ATX power supply salvaged from a PC that I use as a bench power supply.

For a project I'm working on, I have a requirement to butt-join some power cables together.

I am not connected with politics or constitutional law in any way.

This is my second post about the plague of knock-off ICs.

Spot the Chinese knock-off.

They say that a picture tells a thousand words.

My trusty little LED Lenser flashlight stopped working rather suddenly.

I have just finished reading "The Great Crash, 1929" by John Kenneth Galbraith.
