Making a general-purpose PDF editing tool capable of inserting hyperlinks, notes, images, or drawings isn’t exactly a weekend project. The main thing standing in the way of creating such a tool is that the PDF format is a complex and twisty thing. Being an enterprising hacker, set out to fill that gap, and the way it works under the hood is delightfully hacky, indeed. On Windows and Mac machines, it’s not too troublesome to add text or drawings (such as signatures) to PDF files, but found that on Linux machines, there didn’t seem to be a satisfying way or a simple tool. Otherwise, it’s possible that you will find a Wrencher board lying around at Supercon! Now, I’d like to tell you how KiCad 6 made it super easy to design this PCB – after all, there’s never enough SAOs, and it’s quite likely you’ll want to design your own special SAO, too.Ĭontinue reading “Jolly Wrencher SAO, And How KiCad 6 Made It Easy” → Posted in Art, Featured, how-to, Interest, Slider Tagged inkscape, jolly wrencher, KiCAD 6.0, sao, svg This design is open with gerber files available for download, so if you thought of making a quick PCB order, I’m giving you one more. For bonus points, the eyes are transparent, with LED footprints behind them – it’s my first time designing a PCB where the LED shines through the FR4, and I hope that the aesthetics work out! Given the Supercon badge specifics, the SAO-standard SDA and SCL pins have RX and TX labels as well. Those pads are diagonally interspersed with ground-fill-connected pads – if you want to bodge something on the spot, you don’t need to pull separate GND wires. This board gives you an SMD prototyping space, with 1.27mm (0.05″ pitch) pads, suitable for many passive components, ICs and even modules like the ESP32 WROOM. There’s myriads of SAOs to choose from, and if you ever felt like your choice paralysis wasn’t intense enough, now you have the option of getting a Jolly Wrencher SAO board! If you plan to attend Supercon or some other hacker conference, know that you’re going to get a badge with a SAO (Simple Add-On) connector, a 4-pin or 6-pin connector that you can plug an addon board onto.
