I recently assembled the final Outmoded Sequencer PCB and documented the soldering in a short video. I accidentally cut a bottom trace and repaired it with a jumper wire; the magnet matrix now secures the steel balls. I'll finish tone tuning and add four resistors — please watch the video and read on for details.

I received beautiful violet PCBs for my Outmoded Sequencer project and I’m using them to experiment with different matrix approaches. Ordered from OSH Park to keep costs down, these boards make hands-on testing easier. If you’re interested in the build or my findings, please read the full post.

I started the Outmoded Sequencer Project to build a playful, minimal 8×8 music machine using only basic, inexpensive parts and no microcontroller. It loops simple melodies you can edit live. If you're curious about the design and how to build it, read the full project page for details.

I published a minimal data logger that stores sensor readings in the microcontroller's EEPROM, so no external memory is needed. I walk through parts, hardware assembly, and software — plus a deep-dive on the code and usage. If you're curious, please read the full documentation and share feedback or questions.

I'm concerned my archived documents could absorb moisture in a root cellar with 75–90% humidity, so I built a DIY data logger to monitor conditions inside sealed boxes. I walk through parts, breadboard-to-stripboard assembly, tests and a wiring diagram — please read the full post for the complete build.

I built a small device that detects movement on protected surfaces and plays recorded phrases in your voice to deter the cat. I documented schematics and software details, including SD access, so you can replicate or adapt it. Read the full project notes to learn how it works and ask questions.
