Electronics
A workbench corner of the site: notes from the bench on the boxes that talk, route, and search, soldering iron warming up.
Bench Power On
Trace the signal, follow the net.
Notes from the workbench: standing up the boxes that route packets, answer calls, and search vectors. Power rail up, ground solid, signal flowing.
PWR ON · 3V3 / 5V rails nominal · GND tied · NET continuity OK · scope on CH1
Power rails up · grounds bonded · continuity checked across the board · probe on channel 1. More builds get soldered as they happen, not before.
Bench / Lab log
- 001 Building a VoIP PBX Standing up a phone exchange on Asterisk and FreePBX in Docker, with MariaDB and Fail2Ban guarding the line.
- 002 Firewalls How a firewall guards a network: filtering traffic at the edge while still letting the outside world reach in.
- 003 Milvus An open-source engine that searches by vector similarity: the data plumbing behind image, audio, and recommendation systems.
Thin shelf for now, more soldering in progress. The pure hardware builds get posted here once they actually work on the bench.

VoIP PBX answered its first call
Stood up a phone exchange on Asterisk and FreePBX in Docker, with MariaDB behind it and Fail2Ban guarding the SIP line. Dial tone at last: the first build logged on the electronics bench.
