Did you hear about the Rabbi who didn’t charge for circumcisions?

He only took tips!

I don’t charge friends for repairing their electronics, which I’m always glad to do and genuinely enjoy.  But I’ll happily accept a bottle of wine as a token of appreciation.  Sometimes people are really happy to get their stuff fixed.

Look at the pile of swag that my overly generous friend laid on me for putting a new LCD screen in her MacBook Pro!!!

Booty!

That’s two bottles of (very good) wine, a trivet from Williamsburg, a rotary cheese grater and a bag of tasty nuts.  Youza!

A month of many Macs

iMac glass panel

The 500 GB hard disk in my friend’s circa 2008 24″ iMac started making ominous clicking noises last week.  Anticipating its near future death, we took a full backup and ordered a bigger 1 TB drive from Amazon.

Apple never ceases to amaze me with the variety of ways they find to hide fasteners (and make upgrades and repairs to their equipment nightmarishly difficult).  In the case of this iMac, one needs to remove a glass panel held on with magnets to gain access to the internals.  The panel can be removed with a couple of these fancy suction cup tools but I prefer to do it ghetto style with a couple of sink plungers.

After pulling off the glass panel, removing around three dozen screws of at least eight varieties, and unplugging several needlessly fragile connectors, the display panel can be removed and the iMac’s guts are exposed.

The actual hard disk swap is a walk in the park.  Reassembly brings one extra reward.  The combined effect of the glossy LCD display behind the glossy glass cover is a fingerprint magnifier that exceeds the capabilities of the world’s finest CSI labs.  It took six [expletive deleted] install/test/remove/clean cycles to get a smudge free display.  Thanks Apple.

 

Six hacks from 5 grams of Sugru

If you’re not familiar with Sugru, you should be.  It’s a moldable rubber compound that can be formed into any shape and cures at room temperature.  Sugru is amazing stuff.

Sugru comes in little 5 gram pouches in various colors (which can be blended together to create new colors).  The contents of each pouch needs to be used pretty much immediately after opening so I always try to batch my hacks/repairs to utilize a full pouch.  This might be my personal best–six objects improved with one pouch of Sugru!

This otherwise lovely set of fish plates had rough, scratchy bottoms.

A few rubber feet later, problem solved!  Tip:  after forming each rubber foot, place the object right side up on a piece of waxed paper and press lightly to flatten and level the feet.  The waxed paper will peel off easily after the Sugru cures (around 24 hours).

Same problem and same solution for this nice Spanish platter.

Now what to do about about an otherwise perfect place to keep a bedroom clock radio?  (The problem is that it isn’t possible to see the “alarm off” button without getting out of bed and kneeling down.)

Well, let’s just add a nub of Sugru to the Off button and feel it instead!!

There you go.  Six objects improved for an investment of a few minutes time and under a gram of Sugru each.

Blowing a pull string through conduit

I learned a nifty trick the other day.  If you need to run a pull string through a length of electrical conduit, there’s a faster, easier way than pushing the string through with a fish tape (the way I’d been doing it for a very long time).  Use a shop vac to blow the string through.  One advantage of this technique is that you can quickly get the string through very long sections of conduit.

You’ll need duct tape, a couple of baggies and some pull string (you can get the fancy pull string if you like but any lightweight poly cord also works fine). 

Cut a hole in big enough for the shop vac hose in the closed end of the baggie and tape it around the hose. 

Cut another hole just slightly larger than your pull string and insert one end of the string in the baggie and pull it out the open end. 

Now make a “kite” to help the air carry the pull string though and attach it to the string.  For small diamater conduit those disposable foam air plugs work great.  For larger conduit, you can use a pingpong ball if you have one handy or a little parachute made from another baggie. 

Insert your “kite” into the conduit and tape the end of the baggie around it.  Insert the shop vac hose into the blower fitting and turn the vac on.  The baggie should form a relatively airtight seal around the conduit and the string will carry through the conduit as you feed it into the baggie.  If the string doesn’t travel all the way through the conduit, pull it out and adjust the size/material of your kite.

When you’re ready to pull cable through the conduit, don’t forget to pull another length of pull string at the same time so you’re ready for future pulls!
