I’ve got Synology’s cheapest two-bay NAS at home, and man, do I love it. But…

The fantastic STM32 Discovery boards from ST Micro all come with an embedded ST-Link/V2 debugger onboard, including some jumpers to disconnect it from the target device for use as a standalone SWD debugger. Presumably, this is to allow for easy use debugging a custom end-product PCB, but it’s also useful if you have any other STM32 evaluation boards hanging around with no built-in debugger, but don’t happen to have a proper JTAG dongle handy. Here’s how to make an adapter.
In case you missed some of the subtler points of the Aeropress system, these pictures may help.
I just installed a UPS the other day (an older Back-UPS XS1300, pictured) and noticed on the back it’s an “approximate sine wave” output. After reading the bottom closer, it’s specified that the device, under 25% load, has a THD of 55% and a maximum harmonic amplitude of 43% of the fundamental’s amplitude. Sounds pretty bad, but what does that really look like?
I love Powerline. Unfortunately, setting up just about any linux-centric software on windows is an everloving pain in the ass. Powerline is no different, and there don’t seem to be any start-to-finish this-is-what-worked Windows guides. Here’s mine.
This will be effectively a copy of my previous post, but targeted at OS X. The gist is, get a toolchain, debug connector, and open-source firmware library set up to use the STM32F4DISCOVERY dev board from ST as quickly as possible on OS X. Unfortunately, it’s not QUITE as easy as on Ubuntu. Fortunately, it’s not a lot worse.
This tutorial follows the same basic outline as this post on cu.rious.org but some things have changed since that was written such that it no longer works unmodified, and the various similar tutorials leave some bits out. My goal here is to get some custom code on the STM32F4DISCOVERY board as quickly as possible, hopefully paving the way in the near future for a full eclipse-based IDE setup.
