I ordered twenty bare boards from JLCPCB on the seventh of July. They landed a week later, about three weeks earlier than I had planned for. The first bare one is what got me. I made that. Up to that point it had only ever been a render on a screen, and here it was as an actual object with the Bit Haven logo printed on the front of it.https://blog.wolftech0110.com/posts/building-a-hackerspace-badge---part-4---ordering-the-boards/Sun, 02 Aug 2026 00:00:00 +0000https://blog.wolftech0110.com/posts/building-a-hackerspace-badge---part-4---ordering-the-boards/Part 4 of 4 — Building a HackerSpace Badge · Previous: Designing the Badge in KiCad This was my first time ever ordering a real PCB, so getting the badge from my screen to a factory was its own small adventure. Exporting the Gerber files, the manufacturing files a board house actually needs, was the fiddliest part of the whole thing. Once I had those sorted, uploading them to JLCPCB was smooth.https://blog.wolftech0110.com/posts/building-a-hackerspace-badge---part-3---designing-the-badge-in-kicad/Wed, 29 Jul 2026 00:00:00 +0000https://blog.wolftech0110.com/posts/building-a-hackerspace-badge---part-3---designing-the-badge-in-kicad/Part 3 of 4 — Building a HackerSpace Badge · Previous: Building on the Breadboard · Next: Ordering the Boards A working breadboard is a promise, not a product. To actually get a badge, I needed to turn that circuit into a PCB, and that meant laying out a board in KiCad. I had already drawn the schematics in KiCad, but I had never laid out a board, so I leaned on YouTube tutorials to find my footing.https://blog.wolftech0110.com/posts/building-a-hackerspace-badge---part-2---building-on-the-breadboard/Sun, 26 Jul 2026 00:00:00 +0000https://blog.wolftech0110.com/posts/building-a-hackerspace-badge---part-2---building-on-the-breadboard/Part 2 of 4 — Building a HackerSpace Badge · Previous: Finding the Circuit · Next: Designing the Badge in KiCad I built the 555 flasher circuit on a breadboard, and getting there took a bit more work than I expected. I had to knock the rust off the 555’s pinout, and I was working off someone else’s schematic. Even with it in front of me I made mistakes on the breadboard and had to track them down before it finally ran.https://blog.wolftech0110.com/posts/building-a-hackerspace-badge---part-1---finding-the-circuit/Mon, 20 Jul 2026 00:00:00 +0000https://blog.wolftech0110.com/posts/building-a-hackerspace-badge---part-1---finding-the-circuit/Part 1 of 4 — Building a HackerSpace Badge · Next: Building on the Breadboard One night at Bit Haven, one of the founders mentioned wanting a custom badge for the space. They weren’t sure exactly what they wanted, but I let them know I had a degree in Electronics Engineering and could probably make one. That conversation kicked off my journey toward building the badge. For anyone who hasn’t been to one, a hackerspace is a community workshop where people share tools, benches, and knowledge to build things such as electronics, software, hardware, cybersecurity, whatever you’re into.
