Awww... on my part. My overkill battery will in fact kill my altimeter.

"The largest lithium polymer battery that should be used with the Raven is 1S, 300 mAhrs, because larger lipo batteries can produce currents well in excess of the 22 Amp rating of the deployment channels in the event of an output short circuit, which can permanently damage the altimeter."

Better to find out now, but that's back to the drawing board on my sled.

The battery is a 7.4V 1200mAH quadcopter battery, which is definitely overkill, but my motto appears to be "anything worth doing is worth overdoing" and I'm leaning into it.

It's getting a new sled (which itself took 5 or 6 iterations to get right) and a new altimeter, the brand new Featherweight BlueRaven. I'm waiting on some wiring connectors which should arrive today. Also has my new favorite switch, the Lab Rat Rocketry pull-pin switch.

My current project, since I've decided to stop feeling guilty about jumping around between projects, and just do what makes me happy at the moment. I'm refurbishing an old (~7 years old) rocket, Black Widow. This is my favorite kind of rocket to fly, 54mm motor in a 75mm tube. But it's had some usability issues that required some more iteration.

This should be good enough. They only have to stay on for a few seconds.

Just a reminder, since I have seen this constantly for the 20+ years I've been working in IT:

When confronted with a problem, try the simplest solutions first. For whatever reason, people usually go right for the complicated stuff.

People in a hybrid meeting this morning could barely hear the person Zoomed in. They spent 20 minutes messing with the A/V in the room, and the A/V settings in Zoom, before calling me.

I turned up the volume on the laptop.

Problem solved.
