CD4060 oscillator, max resistor value

Aug 03, 2007 84 Replies

I do clean them, but I do it at least a dozen at a time. I use the air compressor to get the loose stuff out, then stand them almost vertical, (On the long end) and spray a fine mist of ammonia, followed by water to rinse the sticky crap out. Let them air dry for a few days, and keep the ones that work again.

At worst I vacuum with a little specialty vacuum I have for PC's.

Spills are considered death and I toss.

I try to keep my wine on the writing desk, not the PC desk ;-)

Or the keys won't go down all the way because of all the hair you've been pulling out.

I like better keyboards than the free ones.

No stash of spares here. I'm married ....

They would have to be from the shepherd mix. Mine's already all pulled out ;-)

No basement, eh?

Here's a calc for my keyboard repair:

Drive to store: 25 min. Time to find keyboard there: 5 min. Wait in cashier's line: 5 min. Drive back to office: 25 min. Grand Total ---> 60 min.

in contast to

Get Philips screwdriver from lab: 1 min. Take it all apart: 2 min. Step outside and shake coarse stuff out: 2 min. (make sure wife doesn't see that...) Hose it all off, scrub a bit where it's nasty: 10 min. Put it all back together: 10 min. Grand Total ---> 25 min.

Ok, method 2 doesn't include a few hours of drying time but my services are not needed for that, it all just sits there in the toasty garage while I work, walk the dogs, whatever.

Ain't nothing like an ice cold cerveza while doing Gerber checks :-)

Open closet. Pick one off the top of the stack. Plug in.

I'm not, and I have a 1200 Sq Ft. garage for a workshop, along with three spare bedrooms in the house. I also have a 12' * 28' storage building, and two 12' * 12' out buildings.

I guess N. is more tolerant with respect to "packratism" than M. I would not get away with such a stack.

Nope. Houses in California rarely have basements. They also do not have attics, at least none where electrolytic capacitors inside keyboards would survive more than one summer.

There you go. I have two rooms (one big, one huge) that are 100% that way. They have doors, if anyone doesn't like the way they look. ;-)

M.'s point of view: OUR closet, OUR office :-)

The upside is that she cleans the office and the lab. I probably wouldn't do such a good job of it. Also, sometimes I have clients here so it can't be too messy or cluttered anyhow.

Ditto my garage. I have things stored out there that I just realized are probably permanently disabled! I know it can hit 130 in there...

It's not so bad. If the gear is of significant value it can often be restored by a blanket-swap of all electrolytics if it turns out that some have dried up. But that won't be economical for a keyboard that retails at $20.

My take is that if equipment cannot stand such exposure it wasn't good in the first place.
