content: 14pin DIP broken out into what? I mean, you can already put a 14pin dip IC into a breadboard, so breaking it out into 0.1" headers seems pointless to me. Unless I'm missing something.Maybe you meanta DIP proto board?

content: You can find them pretty cheap on Amazon, AliExpress, etc. Unless you really want the PCB etching/manufacturing experience, I'd just buy one already made like the ones I linked above.

content: Quote from: p.larner on March 11, 2024, 12:38:43 amThere ya go. That's about as close as you're likely to get unless you actually use some mouth words to precisely define what you want. (or just draw it with a sharpie, which would likely be faster)

content: i want something where the track from the 14 ic pins allign on one side in a row with big pad to solder too,or 2 rows of 7 pads next to eachother in a line with say a 10mm gab between the 2 rows of paralell pads,its hard to explaine .

content: You mean something like this? Do you really want 10mm between pads? With 4mm pads, that would make the PCB 88mm long.

content: EasyEDAis a good tool for these. It runs in your browser (and requires an internet connection), but is easy to use, free, and integrates very easily with JLCPCB.

content: Guerilla breakout boards out of single-side veroboard:The idea is to cut the veroboard pads in half, such that each newly created copper half-pad will match the SOIC footprint.Pics fromhttps://hackaday.io/project/7574-the-devil-is-in-the-details/log/26074-diy-breadboard-friendly-soic-breakout-boardsLooks easy, but it's way more time consuming than soldering chips on proper breakout boards. Either way, it is preferably to use round pins if you intend to insert the breakout board in a breadboard. Square pins are cheaper and easier to source, and they still fit in a breadboard, but they are much too thick for breadboards.

content: Thanks kim,thats ok,but any idea how to make the tracks black on a white background,i cant see how to do that,if i print in greyscale it is no good for toner transfer,regards Paul.

content: 10 mm between pads may be hard to do, and most important, it is not very practical for breadboards set to 0.1" spacing as is your DIP. Clue: 1/2 of 2.54 is a prime number.If you only want to increase the spacing by 2, 3, 4... x0.1 inch increments, then look into a solderable breadboard as provided by SparkFun and others. I prefer SparkFun versus the much cheaper alternatives, because the connections between holes is only on one side. That seems pellucidly obvious to me for signals, but apparently didn't meet some other criterion for the vendors of those cheaper boards. In any event, use short jumpers to expand the 0.1" to any reasonable decimal inch spacing you want, and cut with a Dremel, spherical spur bit the connections that are a problem.

content: A good tool for drawing such artwork isInkscape, which is free and available for all OSes.For example,PDIP-14 0.4" wide; 1.6mm pins at 0.1" spacing 0.4" wide, 0.7mm traces, 7.62mm×5.08mm pads:It is not "just" the artwork, it also contains a useful Inkscape template for working in millimeters but with a 0.1" = 2.54mm grid. The pins and pads are all clones, so changing the top left one changes all of them. Similarly, the top left four traces are cloned for the other three quadrants, symmetrically. In theFile>Document Propertieswindow,Metadatatab shows you its title and author (me), andLicensetab shows it is dedicated to public domain via CC0-1.0 license. As it is SVG format, it is vector graphics; and if you open it in a text editor, or in a browser andView Source, you'll see everything it contains because SVG files are plain text (an XML format, this one usingSVG 1.1 specification).SVG is simple enough to generate from your own script. For example, you could just generate the pins and pads, and then use Inkscape and the Pen tool (below the spiral) to draw nice old-timey curvy traces.

content: Quote from: p.larner on March 11, 2024, 12:38:43 amDo you by any chance have a GPS plugged into your computer? There is a known problem where Windows confuses the GPS data stream for mouse data.Alternatively, are you operating your transceiver without sufficient RF suppression? Prior to fitting an FT240-31 ferrite in my transceiver USB lead, I would often get random mouse jumps when transmitting 50W FT8.
