RISC-V emulator for 8051. Such a beautiful hack. https://GitHub.com/cyrozap/rv51

Refusing to communicate with your coparent is a terrible parenting strategy.

Firmly into negative spoons territory tonight.

Situation: cozy

Ugh. I used fiancée and had to deal with the awkward exchange frequently. Even now when I mention my spouse, everyone wants to assume wife. 😡

Not going to finish with this tree today

I'm at that point in my career where people buying computers from their formative years are buying machines I worked on.

Played Tony Hawk Pro Skater all evening like a proper adult

Really need to figure out a better chute for Big Chippin'. Filled the truck bed but dumped 6" of chips on the ground, roof, hood, ...

Perfect new arrival for a rainy October day

Checked alignment on microscope today. It's so far off that the normal adjustments can't compensate. Guess it's as good a time as any to open it up and do a thorough cleaning.

How to assess a secure MCU:
1. Beg for a datasheet
2. Sign NDA
3. Buy an eval board
4. Load program to dump ROM
5. RE ROM
6. Find undocumented registers and devices
7. Disbelief
8. Pick another device, repeat

Security through hiding rows in Excel 😬

Bought a preheater. Reworking TQFP-100 with an exposed pad is a breeze now.

Totally normal walk to the mailbox.

I use this quite a bit to modify binaries in shell script or makefiles when I'm prototyping. Decent example: https://github.com/SymbiFlow/prjxray/blob/6b7af3b1686b82773c9b09e0f2692196896b4dc1/minitests/partial_reconfig_flow/Makefile

Today's trebuchet progress: frame mostly built. Need to work out pouch design and quick release.

Planning a trebuchet build with my kids. Started with some drawings and calculations.

"hidden coprocessor" is exactly what I want in a security-focused microcontroller: https://www.nxp.com/docs/en/application-note/AN12868.pdf
