This is a brief review of the capabilities and ease of use of three of the most interesting, innovative and downright disruptive web-based EDA tools:

Autodesk 123D Circuits (formerly Circuits.io)

The same simple astable multivibrator circuit is entered into each tool and the design process followed through simulation (where offered), to PCB layout and Gerber download.

This is a quick post about EAGLE parts list generation script which I was written to replace existing “part2html.ulp”. This script generates more organized and detailed BOM HTML file and it can directly replace “part2html.ulp”.

This script is tested with EAGLE 6.6.0, but it can also work with older versions of EAGLE software.
This script is available to download at github with usage details.

This is a description of how I designed and built my UV exposure box. After experimenting a bit with dry-laminate photo-resist and liquid UV hardened solder mask I decided to stop trying to improve my toner transfer technique and rather build a proper UV radiation unit for making printed circuit boards.

I wanted it to be powerful and compact so I decided to use UV LEDs as the UV source. The preferred wavelength for the LEDs would probably be 365nm, but those LEDs turned out to be hard to find, and very expensive. The 395nm-405nm LEDs on the other hand are very inexpensive. And best of all, can be bough as high-density LED-strip’s on 5-meter rolls. So I bought two “5M Ultraviolet 395nm 3528 SMD LED” rolls that have 120 LEDs per meter for a total of 600 LEDs per roll. From what I could tell from a bit of googling the wavelength should work even though it is not ideal. Initial tests proved that the 395nm LEDs worked very well.

What do PCB production and fake fingernails have in common? They both use UV light sources of high intensity and, as luck would have it, those light sources have exactly the same wavelength. Only the ones for PCB production are usually quite costly and the ones for fake fingernails are a bit more competitively priced.

This instructable is about how to use such a device to build a low cost light source, suitable for exposing the various UV sensitive materials encountered in printed circuit board production, like dry film photoresist and UV curable soldermask.

Altium have decided to release their PCB design tool CircuitMaker as open beta. It will be available worldwide to all interested electronics designers, electronic makers and the hobbyist community as a free software offering. Anyone interested in participating in the open beta can register now at the CircuitMaker website.

The open beta testing program allows anyone to download and begin using CircuitMaker today and become part of a growing electronics design community where designs can be shared and collaborated on. The company anticipates that this open beta process will also provide feedback and input to help refine CircuitMaker and make it a useful design tool for designers in the maker community.

In the last ten years, the technology for manufacturing lightweight, flexible PCBs has made huge progress. Lightweight flex circuits are usually associated with materials like Kapton. The use of those materials is typically limited to high-value applications due to price. Fast forward to 2015, and the landscape has changed dramatically.

Printed electronics makes the news on a regular basis. We hear about breakthroughs in printing semi-conductors, organic photocells, or triboelectric fabric. What often goes unnoticed is that the underlying circuits – manufactured on low-cost flexible substrates with copper traces – have quietly moved from the lab to the production floor. Printed copper flexible circuits are now routinely manufactured by the kilometre in a reel-to-reel process. As production volumes go up, costs come down.

In this instructable I am going to show you how to make your own printed circuit board business card. I feel that these business cards will really help you stand out from the crowd and make a great impression. It might even add one more skill to your resume. Everyone that I have given these cards out to has been really impressed and thought it was a great idea. I have regular business cards as well and I only selectively give out my circuit board cards. You can take it to the next level by soldering different circuits on the cards. I made one of my cards into a standalone Arduino.
