Other options exist. Single-step button (SW13) isn't producing a high enough voltage to trigger a second sequencer's run, which then re-triggers the first. More feature ideas: Trigger out - GATE out - could be done externally with a 7-segment display with LED and photoresistor 3 Lead Plastic Package OnSemi CASE 100AQ for QRE1113, see https://www.onsemi.com/pub/Collateral/QRE1113-D.PDF OnSemi CASE 100AQ for QRE1113, see https://www.onsemi.com/pub/Collateral/QRE1113-D.PDF OnSemi CASE 100CY, light-direction upwards, see http://www.kodenshi.co.jp/products/pdf/sensor/photointerrupter_ref/SG-105.pdf package for Everlight ITR8307 with PCB trace layout 4efd2875e8 Replaced accidentally dropped Fine tuning hole. 52b504dd7c Delete 'Panels/futura medium bt.ttf' From 496e3e33446b55a1a2a83a967e779b5254a33381 Mon Sep 17 00:00:00 2001 Subject: [PATCH] Add schematic, start on PCB sandwich, making some final-ish decisions about connecting to front panel to PSU PCB (will affect choice of sitching hardware). Consider aesthetics and prcticality of stand-offs from front panel.
