Toys In The Attic

FIRST Contortions

I’m a manufacturing/electronics/design/theory mentor on a FIRST Robotics team. The last six weeks have literally been a blur. This post is a sleep-deprived ramble.

You’ve been warned.

Turkey and Solder –or– Busy Busy!

After a whirlwind of activity, a lot of which I need to document here, I’m back online!

First of all, I wish you a Merry New Year and for those that took time off this season. Hopefully you’re back with renewed vigor to tackle that project you’ve had on your mind, or an old project that’s on your workbench.

Me? I couldn’t stop working away. Time off feels is nice; I put my toys aside while working on projects at work, and having time off gives me the time to work on my personal projects. I can only describe it as a runner’s high.

A Mystery!

My HP oscilloscope has a curve tracer function… ?!

This is a ‘built for Amdahl’ HP 1725A oscilloscope.

I bought this ‘scope maybe six+ years ago but just last year I noticed that there’s a curve tracer function tied to the intensity knob. The back states it’s an option ‘H01,’ which does not exist in any HP literature, and I couldn’t get any info from HP / Agilent. As far as I can tell there are no curve tracer specific inputs (option 101 includes the 1607A logic-state analyzer inputs), but if you look at the first photo, this was a unit built for amdahl.
