Hey, old geezers. It's been few years since I've been away, mostly due to illness.
Just passed by to say "hi". 8-)

My girlfriend just got a x250 and I was quite disappointed about the keyboard on it. It commits the cardinal sin of squishing keys up: the punctuation just to left of the enter is not full width. The US (ANSI) versions of X240/X250/X260 are alright and don't have key irregularities. Biggest gripe i...

So, there's one other person in the world who uses Nano … Heh. It is a bit of a paradox. I am stuck to the basic toy "nano" because of inertia and laziness, yet I miss the power of the editors I was so productive and comfortable with before that. And as noted, the similarity of nano/*pine is anothe...

Clink? The cooler? On ice? The can? The pen? The chokey? The pound? The tollbooth?
"pen" is more of an abbreviation than slang, right?
The rest are all new to me.

The "fence" is close in visual meaning.

Couple of decades ago, a friend jokingly called the '#' symbol "a prison", because of the bars. Otherwise it was the musical "sharp" for us.

Once I knocked an opened bottle of acetone over the bottom case of my then main (and only) keyboard G84-4100. Not very pretty to look at, but not noticeable in normal position.

Just my nostalgia, and why I feel so at home with DCS and thin SP keycaps. Owning real MX, or any other kind of microswitch board, here in the 90s was prohibitively expensive.
I also paid more for my Silitek for not having Cyrillic legends.

This one is around 1992. Weird number of diodes - about 18-19 of them. I am laughing more at the MX compatible sliders. No wonder the first SP DCS keycap set I got looked strangely soothing to me. Maybe I will clean this beast a little. Any good way to clean the domes and the graphite spot on them? ...

Right, slider over rubber dome with graphite center, shorting PCB pads. i8049 for the brains. The usual for that time AT/XT switch. A different colored dome for the spacebar. Silicone grease still present on the spacebar stabs. Somebody resoldered few diodes, quite unskillfully. The copper side of t...

matt3o, they look good now. Maybe include the dimension (A) after the numbers for future reference?

HHKB turns into the 0.6 W (600 mW) range, which matches my rough ballpark.

If you calculate power by P = V x I, for example HHKB results in 6 W. Also PS2 is rated at max 275 mA. all keyboards are USB. the cherry ML draws 100mA at 5V (which is exactly how much cherry says) HHKB should draw less than 200 mA, if I am not mistaken. Also, USB devices cannot draw more than 500 ...

No, not missing it. :) I said already that "MCU will dissipate less".
The point is that the linear regulator will still dissipate comparable energy to the rest of the circuit (ratio roughly about 2/3). About 66% efficiency for 5V -> 3.3V conversion.

Not connected to the Teensy specifically.

Optimizing the firmware is not that hard and ATmega can also have low consumption. Going to 3.3V or even lower will incur some loss in the regulator or impose complex DC/DC solution. it's actually pretty simple https://www.pjrc.com/teensy/3volt.html That's the trap - this is a linear regulator.

Nice work, Halvar. With LEDs in the 30-50 mW range, they must be putting cheap LEDs at about 8-10 mA current. I like the G80-3000 consumption, that's quite reasonable. I suppose the G84-4100 should be similar (it's not even NKRO), but all mine are PS2 and I don't have PS2 anymore. Optimizing the fir...

Nah. HHKB was my travel keyboard because of size/features, otherwise I wouldn't touch Topre domes.
That's really not the end of the world, though.

If somebody else has done measurements - please share. Mine are too imprecise to be worth documenting in Wiki, so take them with a very big spoon of salt.

Yes and no. This one particular laptop keeps below 5W at idle (and I could shave few more percents). Most of the time I just stare at the screen, and I specifically bought extra battery to have over 20 hours of being brick-free. Having the keyboard drain roughly 1/7th of the power at idle is meh .
