I’ve been prototyping load-sensing barbell collars that give a silent haptic buzz if plates drift or the sleeve starts to walk — 1.8 mm displacement threshold, coin cell lasts about 8 weeks — and I’m debating keeping it collar-based vs. moving the sensing to a low-profile rack clip. For those running high-rep sets or mixed plates, would this improve session flow or just add noise to the gym experience?
I keep a $5 flexible tape in my pocket and do waist-to-height during cardiac lifestyle visits; in a “limited timeframe” it gives me a concrete number to anchor the conversation and a simple trend to revisit. Small caveat: it’s not great for very muscular or pregnant patients, so I’ll lean on their home scale app trends in those cases.
@OP I’d use this on high-rep EMOMs with mixed bumpers — on cycling cleans, a subtle buzz at “1.8 mm” is enough to make me nudge a plate and keep rhythm. The one thing that made a similar collar prototype work for me was a quick long-press mute between sets so it doesn’t nag during resets; if not, a low-profile rack clip felt more reliable on split jerks where collars tend to rotate a touch.
Quick win: run a rolling 30-day vendor+requester window and flag bursts of ‘just under a $10k approval limit’ paired with PO edits within an hour or weekend approvals. The 2–4 line-item pad to land at $9,950 is a dead tell. Caveat: milestone contracts can look similar, so whitelist SOW-backed schedules and make approvers cite the SOW ID.
On multi‑ticket PNRs, I append the original ticket to the price call — FXQ/TIN-1251234567890 — so it skips the select prompt that, , slows things down; that nets another about 15–20s on top of your 30–45, @OP. Tiny caveat: it needs TWD present for that ticket; quick ref: Amadeus Service Hub - Amadeus Service Hub.
Tried a similar collar on high‑rep touch‑and‑go deads; the “1.8 mm” cue worked, but I got fewer false buzzes after adding a 2–3s debounce and a second, stronger pulse only if drift continues. @OP I’d keep it collar‑based for mixed plates, but add a quick toggle to tighten to about 1.0 mm for comp plates; rack clips near uprights vibrated and buzzed like a phone on a metal desk. Bonus wish: auto‑sleep after 30–60s of no motion so the coin cell hits 8 weeks.
I’d keep it collar‑based; on high‑rep bench/tempo squats the sleeve shift is the signal, and keeping your “1.8 mm” but auto‑zeroing about 1s after unrack cut my false buzzes — felt like a seatbelt tug when it mattered. The rack clip read j‑hook/rack vibrations for me, so I’d reserve it for warm‑ups; any chance of a first‑rep auto‑zero toggle, @miaS75?
Quick example: our MA sends a pre-visit text that asks, “what’s the one heart-health habit you’ll try this month?” and it prints on the facesheet so I can set a single goal in 2–3 minutes — saves me from turning into a human clipboard, @mbrockman56. Caveat: it’s clunky for walk-ins, so I keep a postcard prompt at the desk.
