From 362e1fa968dcc4547699ca84eccfef3a013768ab Mon Sep 17 00:00:00 2001 From: Me Here Date: Thu, 28 May 2026 08:00:00 -0500 Subject: [PATCH] USB-C power for all devices (no batteries); separate Micro end caps; landing Philosophy MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Power: standardise the whole family on a single USB-C input — drop the Micro's 2×AA and the Stage's 9V DC pedal jack (+ buck/reverse-polarity). Bring a power bank; nothing internal to wear out. BOMs updated (Micro ≈$35, Stage ≈$56) and all copy/cards/READMEs follow. Micro form: detach the two end caps from the body with a gap (set-back, darker end faces) so the TRS/USB-C jacks read as being on the ENDS of the bar, not the front panel. Landing: add a Philosophy section — "program on the web, play on any device" (author once → load the program string into whichever form factor fits) and "USB-C power everywhere — no batteries" (future-proofing rationale).

🛠️ Program on the web, play on any device

+

The website is the workbench. Design your grooves in the PE‑1 editor — + stack meters, set per‑step accents, build set lists — and every pattern saves to a compact + program string (a whole set list to a single code). That same string loads into whichever + form factor fits the moment: the Stage on a pedalboard, the + Micro inline at the practice desk, or an embedded + widget in someone else's app. One engine, one language — you author once and run it anywhere, + choosing the device by the use scenario rather than re‑learning a new box each time.

🔌 USB‑C power everywhere — no batteries

+

Every device in the family is powered over a single USB‑C port — no internal battery to + swell, leak or wear out, and nothing proprietary to replace. Plug into a wall adapter for a + permanent install, or carry a power bank exactly the way you already do for your phone. Standardising + on one connector across the whole range keeps the builds simple and future‑proofs the + project as USB‑C becomes universal.
