Period: 3 days 1 day This is an ADSR envelope generator synth module. Layout and panel are Kosmo format. * [Schematic](Docs/precadsr.pdf) * PCB layout: [front](Docs/precadsr_layout_front.pdf), [back](Docs/precadsr_layout_back.pdf) * [BOM](Docs/precadsr_bom.md) * [Build notes](Docs/build.md ``` git clone git@gitlab.com:rsholmes/precadsr.git git submodule init git submodule update Find and replace last few thin traces, fix teardrops and gnd fill Embiggen traces, add teardrops Embiggen traces, add teardrops 46614f2341 Add 55k-ish resistor to coarse knob (doublecheck this placement). Actual value unclear (see below).
Argument for a 1uF capacitor. 1uF may be brought only in 1000+ for these. Latest commits for file Datasheets/tl074.pdf Add tl074 datasheet/pinout Add tl074 datasheet/pinout Samba Reggae 1 is probably the most common samba reggae rhythm; it's a classic samba clave with rock/reggae rhythms on the mid surdos.
