venam wroteI think that I hate my scissor switches, they are too crunchie.
Where did you get this keyboard?
Did you command it from abroad?
I would love to get a HHKB from Japan.
I'll buy one if they ship to Lebanon.
Well, me and friends got 3 Ducky Shine 2 from Mechanical Keyboards Inc. in USA.
Blue switch, White LED
Blue switch, White LED Tenkeyless (mine)
Blue switch, Blue LED

Yes, I recommend them since they share the high build quality of the Filcos and such, and have per key LED backlight. I've gone to real battle with it a few times already, the sheer weight of this thing is a knockout ;)

Oh yes, saw these rubber o-rings. Planning to get some to silence mine; however, I'm ordering a small sampler kit first to see for myself how each ring feels.
yasamoka wroteThank you for the reply! Do you think they would work well for such sensitive things as keyboard switches?
Yes, because it worked perfectly for the MRI keyboard and the keypad of the 4D ultrasound and both are known to be extremely sensitive.

That's AWESOME!

@xterm: got a huge laugh. Thanks!
Bought used contact cleaner from Radioshack in Lebanon 2 years ago :P

They don't supply anymore...

Bumping this thread again. Does Anyone know where to buy an electronics contact cleaner ?

Karout Mall had them last time I checked as well as Katranji. We got a can a month ago at work
Am not sure why you don't use 95%+ preferably 99% alcohol most contact cleaners are mainly alcohol with an aerosol.

I used to use 99% alcohol, however, the extra cleaning solutions they have in the cans really help when fixing small things like a scroll for a gaming mouse or a button. the solution coming in an aerosol allows the solution to get in the nooks and crannies and helps gets the dirt out of places it shouldn't be in.

I personally have a $50 Logitech M535 Bluetooth mouse that has a problem with the horizontal clicks as well as the scroll wheel, I tried to fix it with alcohol and it did nothing, then I grabbed the contact cleaner spray from work and it worked like magic!
alcohol soaks pretty well actually, i guess you are right some contact cleaners does contain both polar and non polar solvents and may help fix things when alcohol doesn't work. speaking of scroll wheels i had a logitech with a bad scroll wheel nothing helped, i ended up taking it apart and manually bending the contacts which appeared to have worn slighty from use

My mouse was 2 days old when it started to cause problems, I couldn't return it since I got it on sale for a fraction of the price. I guess it was a tiny bit of corrosion or dust of some sort, either way, a tiny bit of spray worked like magic
Btw, in some cases you need to avoid alcohol based contact cleaners, as it is conductive.
most alcohols you find in Lebanon are ethanol which is weaker than isopropyl alcohol found in contact cleaners.

alcohol isn't conductive? i dip entire pcbs in 99% alcohol

99% alcohol hygroscopic.
And even alcohol get evaporated easily, water part in it happily mixes with dirt and other contaminants under SMD chips, especially QFN/BGA/etc, and might remain longer and cause troubles. Sure if you dry them in hot air properly (and carefully, not not overheat anything), it will be fine, but if not...
So on my opinion - it is very handy, but should be used with reasonable precautions related to this matters.
P.S. Usually in non-food-grade concentrated alcohol they should add special chemicals, so people wont drink it or dont use to manufacture alcoholic drinks. No idea if it is done in Lebanon. And these chemicals might not be good for electronics.

It won't happen what you are saying may theoretically be correct but practically it is not even close to being an issue the 1% water evaporates with the alcohol as water mixed in alcohol will evaporate faster you can even use 95% with no issues
look the reason i dip pcbs in alcohol is that you can use water to clean pcbs yes pure water but water evaporates very slowly thus causing issues you mention so dipping pcbs that has water in alcohol basically replaces water with alcohol and u stick them in an oven or blow some heat and it will evaporate in no time and your pcb is as good as new after being worked on with flux or had corrosion

Edit: Denatured alcohol is very safe with electronics additives are usually other solvents
If its denatured with denatonium benzoate(bitrex), that will leave behind conductive residue.
Ethanol generally fine with normal electronics, but as soon as it gets on high speed or high voltage part, it becomes a problem. For high voltage, creepage and clearance is not built for conductive surface (i mean bitrex issue). I am designing such devices, and this is big issue for anything outdoor, if there is no conformal coating. And by the way if there is any, any solvent might become big problem itself, as it might remove or weaken it (depends on type).
If you are cleaning some pads for low speed with cleaning swab - it is ok, i do it too, but if you are dipping whole board or splashing ethanol on everything - it is bad. Because when it gets under smd chip like this, it wont dry out fast naturally, you need to heat up board, preferably approx slightly over 100C.
Anyway, you might get away with random ethanol bottle, or might get like me 2 weeks wasted for nothing, because some water after cleaning stuck under DDR chip, didnt dried even after 1 day, conducted when i turned it on, corroded and caused random memory errors.
