I regret to announce that we are now a two hurdy gurdy household

This was a lovely Kaiser-Fraiser that passed me yesterday. #unusualcarsmastodon

First try at brazing using the gas torch and flux rather than the tig.
It's so slow. Like 1/10 the speed of tig brazing. I have better control of where the brazing fillet goes with gas.
People online are all painting flux on the joint but this says heat the rod and dip it in the flux and that seemed to work. I'll try dissolving some of this in alcohol and putting it on the joint the way I do with silver solder, next.

And I have a little lightbulb go on over my head. Wait, what if the output of the power supply I'm using to drive the pin isn't really linear? The two other engineers working with me both make O faces, and I stick a multimeter on the pin, and yeah, we're all chasing a DAC error on the supply, not an offset on our chip. Sigh. (2/2)

I'm trying to characterize a new IC that can act as a voltage controlled current amplifier: it supplies a constant current as a function of the voltage applied to one pin. We want to know how linear its response is, if there's an offset, blahblah. And there's a periodic linearity error. I change the input voltage step size, and the periodicity changes. People stare over my shoulder. Tooth hisses. What did we do wrong in this design? (1/2)

There's a whole flock (tribe? Murder? Convocation?) of cattle egrets up the street. Usually these are solitary and in shallow water, but there are ~20 of them in a baseball field near my house. These are almost waist high when they stretch their necks all the way up.

And it works pretty well! Now I have to swap out the other two because one is bending.

Maybe someone supplies double set screw slotted repair collars for a 50 year old machine. But I have a lathe and a mill.

Many of the front panel knobs go back to a panel in the back that handles the CRT hardware, and they chose to do this by using long aluminum rods that use shaft collars that attach to the potentiometers using a flex coupling. The shaft collars have two set screws and are slotted for driving the plastic flex coupling. The slot is flat bottomed with sharp corners at the base of the slot, which is a good way to make something that cracks.

We have this 50 year old curve tracer which could easily kill you by accident, so nobody used it, and finally someone asked me to make it safer. I did, and now everyone uses it, and last month it broke from overuse and I just got around to fixing it.
