100 wonderful, amazing people have joined the Flickr Printed Circuit Boards Group since I launched it in July of last year!
The pool features over 400 pictures of printed circuit boards, many of them CC licensed. There’s a little bit of everything, from homebrew board fab to PCB jewelry and even miniatature cityscapes.
If you have some cool PCB images of your own, add them to the pool!
One of my favorites: Car Park or Printed Circuit Board?

The shanzhai of China are a tech trend to keep an eye on. Typically dismissed by popular press as simply the “copycat barons from China”, I think they may have something in common with Hewlett and Packard or Jobs and Wozniak back when they were working out of garages. I’ve heard quite a few stories about the shanzhai while on my most recent trip to China, some of which I will share here.

Big news – the AVR HV Rescue Shield PCBs arrived yesterday! I’m currently testing them and will post information about kits for sale as soon as I verify that everything is working properly.
This is actually the second spin of the PCB but the first to bear the ‘Rescue Shield’ name. The first spin was a one-off prototype to check a couple things out, mostly related to the 5V to 12V step up converter. That design allowed me to fix a couple bugs before doing a production run with the improved design, show below.
So far all I can say is that the step up converter works perfectly. (Yipee!)
More details to come!
Steve Chamberlin created an 8-bit computer from discrete logic and called his project the Big Mess o’ Wires.
The BMOW runs at 2MHz and has 512K RAM and 16K ROM. It is constructed with primarily 7400 series logic and over 1048 wirewrap connections.
The feature list is very impressive:
Here’s a video of a music test from his site:
I am completely blown away by this project. Has someone invited Steve to the Maker Faire?? I want to see this thing in person!
Check out his site and prepare to spend at least an hour looking at all of his plans and construction photos.
Totally amazing.
