![]() Language: C++ GUI: KDE UI Platforms: Linux License: GPL Development is not very active, and documentation is poor. It has a very nice UI, unfortunately only for Linux. It does not support PCB design, but features microcontroller simulation. Platforms: Linux, Mac OS X, Windows, License: GPLĪnother circuit design tool, specifically targeted at microcontroller circuits. However, it does not seem to be widely used and is hardly documented. The website looks out-dated, but the information is actually up-to-date and some of the tools are under active development. OCD is another suite of loosely connected EDA tools. Language: C++ GUI: wxWidgets Platforms: Linux, Mac OS X, Windows License: GPL It is actively developed, has a well-designed code base. The UI is very nice, and also has 3D view of the PCB. It's much younger that gEDA, but nevertheless seems to cover the whole tool chain. KiCad is also a suite of tools, but more tightly integrated. Interesting: gspiceui is an alternative UI for the SPICE package - maybe we can follow its model. We need to find out how we could program our own GUI on top of their EDA libraries since we do not want to go with their GTK/C. Language: C GUI: GTK+ Platforms: Linux, Mac OS X License: GPL Very good and up-to-date documentation and active community. The GUI however is quite cumbersome and outdated. It has quite a long history and is extensively developed. GEDA is a suite of several tools (some of them independent) around EDA tasks. These services are often offered as separate modules wrapped in a software suite. The main services that EDA packages offer are schematic capturing, PCB layouting (sometimes with auto-routing), preparation for manufacturing and simulation. We are looking into these to see whether we can build our efforts on top of them, and whether they can provide us with inspiration on how to do things. More or less comprehensive listings can be found at Wikipedia, Step 10 - Add backing, quilt as desired, and bind.There is an enormous number of software packages out there for doing Step 9 -Press sashing seams inward toward the white sashing. You will have 9 rows of charm squares and 10 rows of sashing. Step 8 -Continue adding a charm square row followed by a white sashing row until you have used all the rows and sashing. Step 7 -Lay 2.5in long white sashing on RST on the top raw edge of the row. Step 6 -Press seams outward towards the white fabric strips. Step 5 -Continue adding a white strip and then a charm square to row until you have 7 charm squares across and a total of 9 white strips across. ![]() Step 4 - Lay charm square RST over the white strip on the right side of the charm square and sew 1/4inch seam down the long side. Step 3 - Lay the white fabric RST (Right Sides Together) over the charm square on the left side of the charm square. ![]() I cut 2.5inch wide by the width of the fabric and added a 2.5inch x 3.5inch piece to make sure it was long enough. Step 2 - You will also need to cut 10 2.5inch wide by 43.5 inch long pieces of white fabric for sashing. Step 1 - Cut white charm squares in half so you will have a 2.5inch wide by 5 inch tall piece.
