From what we’ve seen we’d say [Jianyi Liu] is really good at etching PCBs at home. Now you can learn from his experience. He just published a mammoth guide to fabricating your own PCBs at home. That link goes to his index page which leads to all eight parts of the guide. He starts off by [...]

Some PCB production houses – Seeed Studio and itead studio, especially – allow you to upload a gerber file and receive a printed circuit board very inexpensively. The pricing structure for these board houses is based on predesignated board sizes – 5cm square or 5×10 cm – and sometimes a project is just too small [...]

The folks at SC-3000 survivors have been working on a cartridge capable of storing dozens of games for the ancient Sega SC-3000 computer. The PCB works beautifully, but making a case for their cartridge left them with few options. They could use a 3D printer or simply collect a whole bunch of used cartridge cases, but making [...]

This slmwtch lives up to its name. When the LCD screen is folded back onto the PCB the entire thing comes in at just 2.35mm. That’s including a coin-cell battery not shown above. Wow! Part of what makes this possible is the specialized PCB design. [Anders] didn’t want to add more thickness than the screen [...]

A few days ago, we mentioned the new ARM-powered Teensy 3.0 project on Kickstarter. The creator, [Paul Stoffregen], decided to share the trials of building a test fixture along with a shocking comparison of the accuracy of different PCB manufacturers in an update to his Kickstarter. Because [Paul]‘s Teensy 3.0 has more IO pins than should [...]

Here’s an IC logic project that displays 24-hour time. Planning was the name of the game for this project. [Mattosx] took the time to layout his design as a PCB in order to avoid the wiring nightmare when build with point-to-point connections. Much of the complexity is caused by the display itself. Each of the [...]

[Hao] from Noisebridge showed me their CNC mill being used to etch PCBs. Using copper clad board, this MAXNC 10 mill routes the PCB with decent accuracy. This makes for very rapid prototyping of single sided PCBs. [Hao] designed the PCB using the open source KiCad EDA tool. This was used to draw the schematic, layout [...]

Chaos Communication Congress 27th (27C3) 2010 Abstract: Are you ready to wake up from the cult of Arduino? Tired of plugging together black-box pre-built modules like a mindless drone, copying and pasting in code you found on Hackaday? You've soldered together your TV-Be-Gone, built your fifth Minty Boost, and your bench is awash with discarded Adafruit packaging and Make magazines. It's time to stop this passive consumption. It's time to create something that is truly yours. It's time, my friend, to design your first circuit board. And you'll need a machine to print it. Outsourcing printed circuit board (PCB) manufacture can be expensive and slow. You want your board now, for free. And designing PCB's is hard. You'll make mistakes, and some boards will be wasted. You can etch your own PCB's at home but the process is fiddly, and notoriously difficult to perfect. What if you had a printer that could make PCB's? A rapid prototyping machine for circuit boards. In this talk I will present my progress towards an inexpensive PCB printer by reverse engineering Epson inkjet technology. And I'm not talking about the crappy print-and-bake method you might have seen on the internet. Come and learn about the miracle of microfluidics within the modern consumer inkjet printer, and how to push it to do new, exciting things. I'll be describing some reverse engineering techniques, a bit of electronics circuit design and the potential for 3D microfabrication with inkjet technology. A PCB will be printed and etched live, on stage, at 27C3!
