Treadwell Overlook

Overlooking things since 1984
I thought it might only snow in the morning, but it is starting to stick!  WTF, I’ve already dusted off my bike.

We’ve had a couple weeks of sun, but now it back to the same old, same old

I’ve wanted to to try a standing desk, but I didn’t want to buy anything or spend a lot of money.  After all, I might not like it.

My first thought was to use milk crates, but I’ve used my crates for enough other things that I only have one free one, and I’d need at least three.  I thought about 2x4 and Simpson Strong Ties, but that would be sort of excessively ugly for the office.

Inspiration struck while I was staring at my tetrahedral kite frame - why not make a space frame?

I pillaged my design from radio tower masts and am testing it out with ten pounds of grain, before I risk my monitor.  So far, so good.

I might talk a bit about making connectors and tuning strut lengths to make the structure plumb and level.  Twist is something of an issue with this technique, because the vinyl tube has some inherent twist and 3/16 dowels are not the straightest material, either.  The pre-load from imprecise cuts and connectors also likely adds some (ok, the lion’s share) twist.

the mail showed up, so it’s also new helmet day!
I tried to capture exactly how bright this thing is with the contrast, but it is understated on the screen compared with reality.

Bicycle Season

Spring has arrived and the weather has been nice enough that I am calling it bicycle season.

I ordered a whole passel of parts in anticipation and have spent some time fixing up my bike.  The difference is night and day.  I put a new set of front sprockets on, a new bottom bracket and a new chain.  Cleaned the old derailleurs, adjusted everything and

wow

It is like riding a whole new bike.  Silent pedaling.  Smooth pedaling. Easy shifting.

I wonder why I didn’t do it sooner?

Of course, there are some hazards that go along with early season biking.  I hopped a curb and landed on a fist size chunk of ice and dirty snow that skittered a couple yards out of the way.  My first low side of the year.  Fortunately, it didn’t take too much skin with it, because I was bundled up for the cold.

Finished off my new workbench.  I added the pegboard and overhanging light.  Looks good now, if I do say so myself

In case you happen to be orienting a Porsche 944’s brake caliper pistons, a triangle with a 20 degree angle is helpful.  I used Wolfram Alpha to make one, since I was too lazy to find either a ruler or a protractor.
The cutout should face into the rotor’s rotation.  That means, for the front brakes, it should face to floor.  The consequences for screwing it up are slightly faster wearing pads.

I’m not sure what this big blue fellow is.  It had four leads coming out of the base and claimed that its case was negative.  Big cap?  Vacuum tube?  It is between the part that I think is an amp and the part that steps down and converts the AC to DC.
The transformers above the blue fellow are the parts that weathered time the worst.  The rest of it was in pretty spotless condition.  Must not have been in a smoking office, which is a little hard to believe if it is as old as I think.

I am pretty sure the little three legged fellow is a transistor.  It is, as far as I could see, the only one in the whole unit.
Another interesting thing about these intercoms is that they don’t have separate microphones.  Pressing the switch just changes the circuit the speaker is on, which allows it to work as a microphone.
