I've only heard an airing cupboard being referred to as a hot press in Ireland. I didn't know that term is also used in Manchester.

I find that storing each of my basses in their case / bag when not in use makes the strings last much longer than when an instrument is left on a stand in the open air.

I agree that it's a bad idea to re-use IDC connectors - I'm sure that you really don't want to take the whole thing apart again when they become unreliable.

voltage across c105 : volmeter dc 5.81v This looks a bit lower than I'd expect. What DC voltages do you measure across D40 (or C103, they should be the same thing) R235 R236 (R2 in your diagram) You say that you replaced Q42, what type of transistor did you replace it with? Did you replace Q41? If ...

That's because there is yet another standard that uses USB-C connectors namely DisplayPort 2.0 and upwards. This transports DisplayPort video data via USB-C cables - this is what your Steam Deck provides. This differs from Thunderbolt in that only either DisplayPort or USB are transported and not PC...

When I bought a hub for my Steam Deck I was told that USB-C and Thunderbolt are the same thing. I'll admit I was confused, but the hub he sold me works, so... Recent Thunderbolt devices use USB-C connector but Thunderbolt is not USB, although, confusingly it's likely to be compatible. Yes that's wh...

The Core i7 name was first used for the higher end of the Nehalem range of 45nm processors released at the end of 2008.

They're both RAM. An SD card is static RAM -- it keeps the data when the power is off, and RAM for a PC or Mac is dynamic RAM, or DRAM, which loses the data when the power is off. DRAM might be better called 'forgettory' than memory, as it needs refreshed constantly to remember the data. It is, tho...

Yes, a remote handset is a digital device and modern types are almost certain to contain a microcontroller running some software, but it doesn't necessarily follow that a remote is likely to fail. It is possible for such systems to be reliable and a remote handset being a very simple system helps wi...

I'm not familiar with remote handsets for smart plugs, but the ubiquitous TV remote is, in effect, listening at all times. When no remote button is pressed, the remote's microcontroller will be in a very low power "sleep" mode where it is waiting for an interrupt from a button to wake it u...

Perhaps, but your remote control handset is most definitely a digital system - it will probably contain a low power microcontroller of some description.

Anyway, what would be your thought regarding the whole CPU usage/DMA thing please? It's a topic thats really outside my area of competency I'm afraid. Hopefully someone who really knows this stuff can advise. USB host controllers (the part that is in the PC, Mac or whatever) have used DMA since the...
