Miscellaneous Electronics circuits
Beach40 kicad is an open-source printed circuit board by digideskio, from the digideskio/electronics repository on GitHub. It is a 2-layer board of 200 × 100 mm with 81 parts on 48 nets, routed with 194 tracks and 2 vias.
It is built around the LM386, BC548 and BD139. Its parts include 33 capacitors, 22 resistors, 7 inductors, 5 transistors and 4 diodes.
Teaching myself KiCad, schematic generation, footprints and PCB layout by designing a board for Peter Parker's Beach40 transceiver. More info on the design at http://vk3ye.com/
To get this up and running, you'll need to do a
git submodule init
git submodule updateto pull in the relevant FreeTronics KiCad libraries.
Simple Voice Activated Switch circuit
My version of Pete Juliano's (N6QW) "Let's Build Something" SSB transceiver. Design details at http://jessystems.com/LBS_Detail.html
The only differnce so far is the audio output stages. I had an LM386 on hand, and used that instead, with a 2n3904 audio pre-amp.

It measures 200 × 100 mm and has 2 copper layers, 1.6 mm thick.
81 parts, built around the LM386, BC548 and BD139. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the digideskio/electronics repository on GitHub, at the commit this page was made from: the board is Beach40_kicad/beach40_kicad.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask digideskio before reusing the design.
