RS Components has released PCB Converter for SketchUp, a software tool that converts CAD files in Intermediate Data Format (IDF) to Collada format for use in SketchUp. This enables designers to use SketchUp as a 3D CAD back-end for to PCB design and brings SketchUp into the electronic product design realm. [via]

I am using a positive photo-lithographic process to transfer the artwork to a photosensitized, copper cladded PCB laminate. Positive means, that during the development step the protective coating on the copper is removed in those places that were previously exposed to UV light. So the artwork has to block UV light where you want the traces on the board.

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.
