As the electronics hobbyist one of knowledge that we have to be familiar with is how to make our own printed circuit board (PCB). Making our own simple single side PCB actually is not require a sophisticated technique and technology as you might think, instead most of the required materials is already available at your home. I’ve started make my first single side through-hole PCB for a simple two transistors astable multivibrator project using just a water proof marker and draw the PCB layout directly on the PCB copper surface.

Homemade QFP50 dangerous proto board test CNC precision:

I’m using the QFP50 dangerous proto board as a reference design to test the precision of a proxxon mf-70 retrofitted micro CNC. I’m quite happy with the results!

Panelizing PCB & Assembly: prepping the boards… If you want to send out PCBs for manufacture you can save a lot of money by tiling them, here’s a nice walkthru of using the open source gerbmerge tool to tile your PCBs.. [via]

MickM built flat cable to header converter adapters : [via]

I was using some character LCD displays and realised that the cables were impossible to plug into the displays that I actually had. My PCB was single row of 16, the LCD was 2×7, no backlight. So I made an adapter for it.

erdabyz has been experimenting with soldermask on homemade PCB’s: [via]

I found it like a year ago, and I thought I had to give it a try. Bought a syringe and… my life has changed since then. Once you know how to use this stuff properly, your homemade PCB’s will never look the same.

Todbot of Los Angeles hackerspace CRASH Space figured out how to import vector shapes from Illustrator into Eagle. [via]

Eagle is a great cross-platform, free-for-non-commercial-use tool for many of us designing own own circuit boards. But it has a pretty glaring omission: the ability to import vector artwork to use as board outlines, logos, etc. You can import bitmaps via the finicky “import_bmp.ulp” ULP add-on, but bitmaps can’t work for board outlines. So we struggle with Eagle’s rudimentary vector drawing tools or have boring rectangular or circular boards. I think I’ve found a way to robustly transfer vector artwork from Illustrator to Eagle.

I make a lot of breakout boards that I usually use in my hobby projects. Most are input/output devices but some are microcontroller breakout boards.

I’ve been etching my own prototype boards for many years in a glass tray, using a griddle to heat the solution. The large horizontal area of the solution resulted in lots of fumes that were hard to avoid breathing. The boards etched unevenly (due to hotspots of the griddle) and required a lot of hand agitation (and breathing the awful acid fumes).

One of the most useful types of PCB’s in the world of electronics is the breakout board. Breakout boards offer prototypers easy access to all pins on an IC that normally has tiny leads in SOP/TSSOP/QFN/BGA type packages. If you’re trying to prototype on a breadboard a breakout board will be your savior, especially if paired with standard 0.1″ SIPs.
