I can never think of anything to put here.

This machine sucks, with the finest of precision.

I'm blaming this one mostly on Curtis from CEE, and Igor Negoda. Must have watched too many of their videos I think.

Why are these called "toolmaker's"?

An idea that just would not get out of my head. A lot of improvement still required.

Investigating whether OpenMV H7 is viable as a flyby camera for pick and place, the answer is yes :)

I clamped the X rails to the bench temporarily to try some cuts. It's going well so far, but seriously needs tramming. Not sure if I can be bothered :)

I just turned the camera on and what the hell hey. It was actually only $32. Battery was at 3.8V afterward, so looks like you can just fly it without worrying about damaging the battery.

Can do up to 128 lights at 50Hz

Looks like about 145km/h top speed with this configuration (4S, 1300kv, 8x6)

Quite bouncy in pitch during these flights. Being not too familiar with puller-prop configuration, it only occurred to me after editing the video that the increase in stability at speed is not just from the faster airflow, it's also because it's being pulled from the front rather than pushed from the back.
