Good price. Check out door stops at hardware store.

 

[Zen Mod]

local hardware store - door stoppers ?

(that thing you screw in floor , to prevent door slams in the wall behind)

edit : I don't have F5 on my kybrd

 

[buzzforb]

You tell me what is different from whats listed above.

Never thought of kybrd before.

 

[Zen Mod]

I don't have F5 , to refresh page and see that buzz already buzzed reply

 

[buzzforb]

Ah! Saying same thing. I don't use computer keys. Mouse generation. Kids walk up and touch screen and expect something to happen. Relative knowledge.

Pass is using PCad , drawing pcbs ditto from paper , without PCad sch file

go figure - keyboard is everything

My best days with a word processor type of thing was Aldus PageMaker, in college, and it was all keyboard macros. You only need 5 to be useful, 10 to be fast, and 20 macros in your fingers will make you a wizard. heck, there are 5 I regularly use on my Macs...

whatever I do with my kybrd , they're doing better

You cut your hair

 

[schultzsch]

ok...so I had to choose between silicone pads for isolator which were factory made and teflon isolators which I have on a role and I had to do another hand work
guess what I choose

 

[buzzforb]

What is the thermal performance of the teflon?

 

[schultzsch]

sincerely...I don`t know but from what I know it is better than silicone pads, also thinner and you don`t need to use thermal grease, hope I am right

 

[Zen Mod]

teflon

put goo , just in case

 

[schultzsch]

both sides or one only?

really don`t like very much grease just `cause you get dirty each time you get you hand near...you just can`t miss it

 

[Zen Mod]

well - I put kapton today under few of them , but with goo

getting grease on fingers - just matter of mileage

I'm using wooden stick for applying goo (meat spits)

 

[schultzsch]

didn`t had on hand kapton, I know it is the best but...maybe in the future if the teflon wouldn`t work fine and the temperature difference between sink and to247 capsule will be too high.what should be the maximum value of this difference?

 

[Zen Mod]

say that 10C is in highish part of ballpark

there are few threads - search for mica and goop and for Keratherm

 

[PKI]

Hm... quick search gives: Therm. cond. for kapton = 0.37 W/(m*K), Dupont web page, and for example for Alum. Oxide = 60 W/(m*K)(Wiki), so it is two orders. Why not just buy Al2O3 based pads?
