I've received a lot of questions about my various open source projects, status of them, etc.
Made a public google doc with everything:

- Just got this absolutely beautiful piece of PCBA artwork done by Usanekorin from @collateralds. Cutest possible way to assemble a board?
- Replying to @azonenbergThe polarizer, though... Here it is in two orientations, 90 deg apart. I'm sold.
- Replying to @KelseyFarishMy wife and I used to keep disposable earplugs in our pockets when our little one was a month or two old and in her intense crying phase. According to NIOSH safe exposure time at this level is about 1.5 minutes per day.
- Everyone needs more custom printed heatshrink in their life 😍
- I've had an HP LaserJet all-in-one printer in my home office for a couple of years now. I finally ran out of black toner and had to swap the cartridge out. The box had this cool anti-counterfeiting seal on it, which changes appearance as you tilt it. Let's take a closer look!
- For all of the C++ hating C programmers out there looking to ruin someone's day... "class" and "template", among other things, are legal function/variable/struct names in C. Sprinkle these around and your API can't be called from C++ code!
- A week or so ago, @femtoduino asked me to help out with troubleshooting and reworking a prototype of the BOMU, a tiny USB-connected microcontroller dev board. It's a super dense six-layer board with multiple levels of blind vias. Here's a bare board after removal of back mask.
- Signs you're having a fun day... No, I did not do this on purpose.
- Open source signal analysis and protocol decode software. Open hardware 5 GHz probe. Now all we need is an open hardware scope that has enough B/W to keep up... Full res screenshot at antikernel.net/temp/pcie-fun.….
- For those of you who complained about the schoolgirl outfits in the previous draft of this picture, I agree! Had the artist redraw them in more reasonable construction PPE.
- This board is a lot of firsts for me so really hoping it works! * First 8 layer design * First 10GbE FPGA design * First SATA design * First DDR3 design * Largest design by area I've done 10GbE on devkits, and built a SFP+ to SMA test fixture. But never to an FPGA on my own PCBReplying to @azonenbergAnd here we are with RAM and optic installed. That's it for tonight, the rest of bringup will have to wait until I have time to write some actual firmware.
- The refactoring I'm working on should have come with one of these placards...
