How to search

sten gun
pages with both words
"sten gun"
the words together, as a phrase
sten OR sterling
either one (| works too)
sten -replica
leave out pages that mention “replica”

Without quotes, the last word also matches longer words that start with it (sten finds Stenophylla), and close word forms count (rifle finds rifles). Tick Exact words to match whole words only.

Whole deep dives are listed first, then the pages inside them.

    Volumes

    1. Vol 1 Overview & Decision Tree What a scope clock is, the six ways to get one, and which path fits
    2. Vol 2 How a CRT Vector Display Works The electron gun, electrostatic deflection, phosphor persistence, and why a clock is drawn as strokes
    3. Vol 3 The High-Voltage Power Supply The rails an electrostatic CRT needs, the two ways to make them, and how to tame the ripple without dying
    4. Vol 4 Deflection & Video (Z) Amplifiers Turning a 3.3 V DAC output into push-pull plate drive and a fast cathode blanking signal
    5. Vol 5 Timebase & Vector-Drawing Firmware The MCU, the DACs, and how the face is actually drawn — keeping time, steering the beam, and beating flicker
    6. Vol 6 CRT Selection & Sourcing Reading a tube's spec, the TubeTime compatibility list, the DG7-32 and 6Lo1i pinouts, and where the glass actually comes from
    7. Vol 7 Build A — Dutchtronix AVR Scope Clock (owned) The classic ATmega scope clock: board, document set, firmware, and living with it
    8. Vol 8 Build B — OSC4.4 (owned) The owned OSC4.4 scope clock, built stage by stage: HV supply, low-voltage and wave-shaper, deflection and logic, CRT wiring, bring-up, and the Wi-Fi/GPS modules
    9. Vol 9 Buy a Kit or Finished Unit The low-effort end of the decision tree — Oscilloclock, AliExpress controller boards, the Altoids build, and the kit landscape
    10. Vol 10 Build From Scratch (open-source crt-driver) The TubeTime board set, supplying your own vector source, and rolling your own design
    11. Vol 11 Enclosure, Finishing & the Steampunk Treatment Mounting the tube, taming the high voltage inside the box, and dressing it in brass
    12. Vol 12 Safety, Calibration, Troubleshooting & Cheatsheet The mandatory high-voltage safety brief, the bring-up and adjustment procedure, a fault-finding guide, and a laminate-ready reference card
