# 2026-05-04 — Memory Flush (Pre-Compaction)
|
||
|
||
## Session Start — Swerve Hardware Specs (00:52 UTC)
|
||
|
||
Chris messaged at 00:52 UTC with three hardware links:
|
||
1. SDS MK4i swerve modules — https://www.swervedrivespecialties.com/products/mk4i-swerve-module
|
||
2. NEO Vortex motors — https://www.revrobotics.com/rev-21-1652/
|
||
3. SPARK Flex motor controllers — https://www.revrobotics.com/rev-11-2159/
|
||
|
||
Chris noted: each page has PDF drawings, parts lists, assembly guides, and getting started guides that will be useful.

|
||

## Full Swerve Stack — Team 2890
|
||
|
||
**MK4i + NEO Vortex + SPARK Flex + YAGSL** — the full swerve stack used by Team 2890.
|
||
|
||
Chris noted this is the drivetrain core. Good material for training students on the hardware-software boundary.
|
||

|
||
|
||
## Git Push — Auth Issue
|
||
|
||
Tried to push wiki updates to remote (Gitea). Push failed with authentication error. Remote credentials need fixing or Chris needs to run `git push` manually from `/home/topher/.openclaw/wiki/main/`.
|
||
|
||
**Action needed:** Chris to run `git push` manually or fix remote auth.
|
||

|
||
|
||
## PSB Gemma Test — In Progress
|
||
|
||
Chris said he dropped a beer recipe to Gemma and will ask her about it in a few days. This tests whether the always-refresh rule (added to psb-gemma AGENTS.md in prior session) helps Gemma retain context across sessions.
|
||
|
||
**Test criteria:**
|
||
- Ask: "What's the beer recipe I gave you?"
|
||
- If she knows → rule working
|
||
- If she doesn't → still broken
|
||
|
||
**Day 7 check:** ~May 10, ask Chris how it went.
|
||
|
||

|
||
|
||
## End of Session — 00:58 UTC
|
||
|
||
Chris went to sleep after messaging. Fabric continuing to run in heartbeat mode during off-hours.
|
||
|
||
**Today's additions to wiki:**
|
||
- 3 hardware spec files (MK4i, NEO Vortex, SPARK Flex)
|
||
- Full swerve stack documented for training use
|
||
|
||
**Still open:**
|
||
- Git push auth failure (manual fix needed)
|
||
- PSB Gemma recipe test pending (check in ~7 days)
|
||
- PSB memory problem — always-refresh rule applied, awaiting test results
|
||
- Privacy model — Chris still stewing
|
||
|
||
*Memory flush complete. Heartbeat continues.*

## Session — Canjectors Hardware Documentation (01:30–01:54 UTC)
|
||
|
||
Chris shared his custom CAN bus interconnect system: **Canjectors**. Full documentation session.
|
||
|
||
### Design Basis
|
||
- **SWYFT CANnect** as inspiration — CAN bus + 12V power over Ethernet, Wago connectors, built-in redundancy
|
||
- Chris experienced critical CAN bus failures at competition → designed his own answer
|
||
|
||
### Five Variants Documented (names printed on PCBs)
|
||
| PCB Name | CAN ports | 12V outs | Role |
|
||
|---------|-----------|----------|------|
|
||
| **Endz** | 1 | 1 | Origin — first device in chain, PDH side |
|
||
| **Minor** | 3 | 1 | Mid-chain — single wheel (CANcoder + 2 motors per MK4i) |
|
||
| **Major** | 6 | 2 | Heavy distribution — end of main runs |
|
||
|
||
**Endz also serves as first/last item in chain.** Minor was designed with single wheel module in mind: 1 CANcoder + 2 motors. Major has 6 CAN ports, 2 12V outputs.
|
||
|
||
### All variants feature
|
||
- Shunt-activatable 120Ω termination (any board can terminate the bus)
|
||
- RJ45 connectors
|
||
- Power LED indicator
|
||
- WAGO 2601 terminal blocks
|
||
- EasyEDA design (schematics dated 2026-04-09)
|
||
|
||
### Files received and stored
|
||
- `canjector-schematic.png` — Minor variant schematic
|
||
- `canjector-start-pcb.png` — Endz PCB layout
|
||
- `canjector-minor-render.png` — Minor 3D render
|
||
- `canjector-major-render.png` — Major 3D render
|
||
- `canjector-endz-render.png` — Endz 3D render
|
||
- `canjector-major-gerbers.zip` — 13 Gerber files + drills
|
||
- `canjector-minor-gerbers.zip` — 13 Gerber files + drills
|
||
- `canjector-endz-gerbers.zip` — 13 Gerber files + drills
|
||
|
||
### Wiki file created
|
||
`sources/2890/canjectors.md` — full system documentation
|
||
|
||
### Key insight for training
|
||
Chris's story: critical failure → study existing solutions → custom design → build → test → deploy. Full engineering cycle. Good narrative for students on why ruggedized interconnect design matters.
|
||
|
||
### Endz has design problems
|
||
Endz is a USB-to-CAN diagnostic interface (USB Type-B at top, CAN+12V at bottom). Chris had design issues — no working units yet. If Chris wants to debug, ask about schematic or what's failing.

|
||
|
||
**Still open:**
|
||
- Git push auth failure (needs manual fix or Chris running `git push`)
