Implemented a generic SPI driver for +FreeBSD -- got my MCP3008 10-bit 8-channel ADC up and running, successfully reading out the 5v and 3v3 voltage lines on the +Raspberry Pi 2 itself, compared against a fixed 5v linear regulator as the voltage reference using an external 12v lead-acid battery.

Next stop: implement the BCM2835 pulse-width modulation modes.  It has two hardware PWM channels each configurable to attach to a number of different GPIO pins.  Also, now that I've managed to breadboard up a digital voltmeter, I need to make an ohmmeter.

Finally got +FreeBSD going on my +Raspberry Pi 2.  The July snapshot is okay but the August snapshot root account is locked out, very frustrating having to use an old build but hey, it's good to see buildworld again!

That's too cute

Since it refuses it grow, I'm starting to think I have a House Mouse rescue instead of a Black Rat.  Pretty damn hard to tell them apart!

My LG OS-5040A oscilloscope off eBay seems to be in great working order. Hooked up to my left speaker channel currently.

Got my 2ch 40MHz LG analog oscilloscope today!  Windows 10 is in the house, too!

Pixels was sick. Great use of 3D for once, too.

I can't resist it, will not fight it any longer.
